In the Bible, Psalm 150 tells the faithful to praise the Lord with trumpet, harp, tambourine, stringed instrument and cymbal. In the United House of Prayer for All People, it's all about the trombones. No one knows exactly how trombones ended up in church, but it's an intensely vocal sound.

Description FIELD OF THE INVENTION This invention relates to a stringed musical instrument and, more particularly, to an electric stringed musical instrument with a frame. DESCRIPTION OF THE RELATED ART A violin, viola, cello and double-bass are members of the violin family, and the violin family is essential musical instruments of an orchestra. A standard cello is of the order of 120 centimeters, and is twice longer than a standard violin. The standard cello is four times wider than the standard violin. The double-bass is of the order of 2 meters long, and is almost twice as long as the cello. The compass of a stringed musical instrument is dependent on the length of the string, the specific gravity of the string and the tension exerted on the string. The longer the string is, the lower the pitched part is. For this reason, the compass of the cello is lower than that of the violin, and is higher than that of the double-bass. The string player puts the body of the violin between the chin and the shoulder, and holds the neck with the left hand. The string player takes the bow with the right hand, and plays the violin. The string player plays the viola in a similar manner. However, the string players stand the cello and the double-bass on a floor. The string player sits on a chair, and puts the cello between the knees. The cello inclines toward the string player, and the body and/ or the neck are put on the chest and/ or shoulder, and bows the strings. The double-bass is usually played by a string player standing on a floor. The body is an essential component part of the bowed stringed musical instrument of the violin family, and a resonator is formed in the body. A neck projects from the body, and strings are stretched over the neck and the body. When a player bows the strings, the strings vibrate, and the vibrations are propagated to the body. The body also vibrates for generating tones, and the resonator makes the tones loud. Thus, the bowed stringed musical instrument generates the loud tones through the resonator. Lower pitched tones require a large resonator. For this reason, the double-bass has the largest body in the violin family. A stringed musical instrument with a resonator is hereinbelow referred to as "acoustic stringed musical instrument." The violin, the viola, the cello and the double-bass described hereinbefore are categorized in the acoustic stringed musical instrument. The acoustic bowed stringed musical instruments are prominently used in an orchestra. Although other orchestra members generate tones through other musical instruments in a symphony, the other tones do not drown the tones from the acoustic bowed stringed musical instruments, and the audience can discriminate the tones of the acoustic bowed stringed musical instruments from the other tones in a concert hall. Thus, the string player appreciates the resonator for the loudness. However, the loud tones are often a nuisance to the neighborhood. The string players feel it difficult to seek a practice room. Although the loudness is reduced to some degree with muted strings, it is impossible to keep the acoustic stringed musical instruments silent during the practice. If the resonator were removed from the acoustic stringed musical instrument, the string player would practice the acoustic stringed musical instrument anytime anywhere. However, the resonator or the body is a delicate component part of the acoustic stringed musical instrument. For this reason, the acoustic stringed musical instrument is indecomposable. In this situation, manufacturers for musical instruments offer electric stringed musical instruments such as an electric cello and an electric double-bass. Any acoustic resonator is not incorporated in the electric stringed musical instruments. While a string player is playing a tune on the electric stringed musical instrument, the vibrations of the strings are converted to an electric signal by means of a pick-up, and an electronic circuit imparts an appropriate envelope to the electric signal so as to give the tones the timbre close to that of the acoustic double-bass. The electric signal is supplied to a sound system, and the unique tones are produced in the sound system. The loudness is easily changeable. In fact, the loudness is drastically reduced to a tenth, and the acoustic energy is of the order of a hundredth. The four strings of a prior art electric stringed musical instrument are averaged at -20 dB. The drastically reduced loudness is as faint as whispers of human voice. Using the electric stringed musical instrument, the string player practices a tune at his or her home anytime. Figures 1 and 2 show the prior art electric bowed stringed musical instrument. The prior art electric bowed stringed musical instrument is corresponding to the acoustic double-bass, and is hereinbelow referred to as "electric double-bass". The prior art electric double-bass is designated in its entirety by reference numeral 1. The prior art electric double-bass 1 comprises a trunk 2, four strings 3 and a framework 4. The width of the trunk 2 is increased from the lower end to an intermediate portion, and is decreased from the intermediately portion toward the upper end. In other words, the trunk 2 slightly bulges. The trunk 2 is broken down into a relatively thick base, a relatively thin neck and a fingerboard 2a. The relatively thick base portion is integral with the neck. The fingerboard 2a is laminated on the relatively thin neck, and extends over the relatively thick base. A peg box 4 is formed in the relatively thin neck of the trunk 2, and is provided with a scroll 5. Four pegs 7 are rotatably supported by the peg box 4. The four pegs 7 are associated with the four strings 3, respectively. The peg box 4, the scroll 5 and the pegs 7 are similar to those of the acoustic double-bass. A tail piece 8 is anchored to the lower end of the trunk 2, and is gradually spaced from the other end portion of the trunk 2 toward the fingerboard 2a. A nut 9a is embedded into the upper end of the fingerboard 2a, and another bridge 9b is upright to the trunk 2. The four strings 3 extend between the pegs 7 and the tail piece 8. The four strings 3 are anchored to the tail piece 8, and are wound on the associated pegs 7. The nut 9a and the bridge 9b give tension to the strings 3. Thus, the four strings 3 are stretched over the fingerboard 2a and the trunk 2. The framework 4 is broken down into a yoke 4a and a shaping board 4b. The yoke 4a is fixed to the trunk 2, and projects from a side surface of the trunk 2. The yoke 4a is shaped like a part of the side board of the acoustic double-bass defining the resonator together with the soundboard. The shaping board 4b is fixed to the other side surface of the trunk 2, and sideward projects from the trunk 2. The shaping board 4b is curved like the outline of a half of the body forming a part of the acoustic double-bass. The shaping board 4b is connected at both ends thereof to the side surface of the trunk 2, and is spaced from the trunk 2 between the connected portions. Any soundboard is not put over the space between the trunk 2 and the shaping board 4b. For this reason, any resonator is not formed in the prior art electric double-bass. While a string player is bowing for playing the prior art electric double-bass, the shaping board 4b and the yoke 4a are held in contact with player's body for keeping the attitude of the prior art electric double- bass. For this reason, the shaping board 4b and the yoke 4a are shaped like the body of an acoustic double- bass. An end- pin 10 projects from the lower end of the trunk 2. The end- pin 10 is retractable into the trunk 2. The end pin 10 is pressed against a floor so that the prior art double-bass is maintained over the floor by the string player. Though not shown in the figures, a pick- up unit is provided on the trunk 2, and vibrations of the strings 3 are converted to an electric signal. The pickup unit is connected to an electronic circuit (not shown), and the electric signal is supplied from the pick- up unit to the electronic circuit. The electronic circuit shapes the electric signal into an audio signal representative of the tones close to those of the acoustic double-bass. The audio signal is supplied to a sound system (not shown), and tones are produced from the audio signal through the sound system. The sound system includes a headphone, and the string player hears the tones through the headphone. Since the prior art electric double-bass does not have any resonator, the strings 3 merely generate faint tones, and the faint tones are not a nuisance to the neighborhood. Although the prior art electric double-bass is narrower than the acoustic double-bass, the prior art electric double-bass is so large that the string player feels the prior art electric double-bass bulky. In other words, a problem is encountered in the prior art electric double-bass in the portability. The manufacturer makes an electric double-bass on an experimental basis. The manufacturer eliminates the shaping board 4b from the prior art electric double-bass. However, the electric double bass made on the experimental basis is unstable. While a string player is bowing, the trunk is liable to turn around the end pin. Thus, there is a trade-off between the prior art electric double-bass and the electric double-bass made on the experimental basis. SUMMARY OF THE INVENTION It is therefore an important object of the present invention to provide an electric stringed musical instrument, which is improved in portability without sacrifice of the stability. To accomplish the object, the present invention proposes to make a framework detachable. In accordance with one aspect of the present invention, there is provided a stringed musical instrument comprising a body without a resonator and separable into plural parts, a neck projecting from the body, strings stretched over the body and the neck and an electric sound generating system associated with the strings for generating electric tones on the basis of vibrations produced in the strings. In accordance with another aspect of the present invention, there is provided a stringed musical instrument comprising a trunk, a detachable framework sideward projecting from the trunk, at least one coupling unit connecting the detachable framework to the trunk without forming a resonator, strings stretched over the trunk and independently producing vibrations by a player and an electric sound generating system associated with the strings for producing electric tones on the basis of the vibrations. In accordance with yet another aspect of the present invention, there is provided a stringed musical instrument comprising a trunk elongated in a first direction, a detachable framework projecting from the trunk in a second direction perpendicular to the first direction, coupling units for connecting the detachable framework to the trunk without forming a resonator, a peg box formed in one end portion of the trunk, pegs supported by the peg box and independently rotatable with respect to the peg box, a fingerboard attached to one end portion of the trunk, a tail piece connected to the other end portion of the trunk, strings stretched over the fingerboard between the pegs and the tail piece and independently producing vibrations by a player, a nut and a bridge respectively attached to the fingerboard and the trunk so as to pass the strings thereover and an electric sound generating system having a pickup unit supported by the trunk for converting the vibrations to electric detecting signals, an electric circuit connected to the pickup unit for producing an audio signal through a signal processing and a sound system connected to the electric circuit for generating electric tones from the audio signal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment Referring to figures 3 and 4 of the drawings, an electric bowed stringed musical instrument embodying the present invention is designated in its entirety by reference numeral 20. The electric bowed stringed musical instrument 20 is designed to be bowed in the similar manner to a standard acoustic double-bass. For this reason, the electric double-bass 20 is as long as the standard acoustic double-bass, and is hereinbelow referred to as "electric double-bass". The electric double-bass 20 according to the present invention comprises a trunk 21, a detachable framework 22 and coupling units 23, 24 and 25 for connecting the detachable framework 22 to the trunk 21. The trunk 21 is similar to the trunk 2 of the prior art electric double-bass 1, and no further description is hereinbelow incorporated for the sake of simplicity. The framework 22 is detachably connected to the thick portion of the trunk 21. The framework 22 includes a shaping frame 22a, a yoke 22b and a connecting plate 22c. However, any resonator is formed in the framework 22. The shaping frame 22a is connected at both ends thereof to the rear surface of the trunk 21 by means of the coupling units 23 and 25. The shaping frame 22a sideward project from the trunk 21, and the yoke 22b projects from the other side surface of the trunk 21 in the opposite direction. The connecting plate 22c is curved, and is connected at one end thereof to the shaping frame 22a by means of a pin 26 and at the other end thereof to the rear surface of the trunk 21 by means of the coupling unit 24. The connecting plate 22c prevents the shaping frame 22a from undesirable deformation. The pin 26 permits the connecting plate 22c to rotate therearound. The shaping frame 22a has a contour similar to the outline of a half of the body of an acoustic double-bass, and recalls the acoustic double-bass to player's mind. The shaping frame 22a is broken down into a plate 22d and pads 22e and 22f. The shaping frame 22a is shaped like the Arabic numeral "3", and the pads 22e and 22f are attached to the plate 22d. The pads 22e and 22f are located at the position where string players are held in contact. In this instance, the plate 22d is formed of metal or alloy, and the pads 22e and 22f are formed of wood or synthetic resin. The yoke 22b is a short bar, and is symmetry with a corresponding portion of the shaping frame 22a. The yoke 22b is gently curved, and has the contour similar to a shoulder portion of the body of the acoustic double-bass. As will be described hereinbelow, the yoke 22b is turnably connected to the shaping frame 4b, and, accordingly is foldable toward the shaping frame 4b. In this instance, the yoke 22b is formed of wood or synthetic resin. The connecting plate 22c is gently curved, and is connected at one end thereof to an intermediate portion of the plate 22d by means of the pin 26. The other end of the connecting plate 22c is connected to the trunk 21 by means of the coupling unit 24. The connecting plate 22c makes the span between the connecting portions between the trunk 21 and the shaping frame 22a. For this reason, even if external force is exerted to the shaping frame 22a toward the trunk 21, the connecting plate 22c keeps the contour of the shaping frame 22a unchanged. When the coupling unit 24 releases the connecting plate 22c from the trunk 21, the connecting plate 22c turns around the pin 26, and changes the position in such a manner as to be close to the lower portion of the shaping frame 22a. A rigid plate 23b (see figure 7), a bolt, a knob 23a and a cover plate 23c form in combination the coupling unit 23. The rigid plate 23b is fixed to the trunk 21, and a threaded hole 23d is formed in a central portion of the rigid plate 23b. The bolt projects from the knob 23a. The bolt passes through a hole formed in the cover plate 23c, and is rotatably supported by the cover plate 23c. The cover plate 23c is fixed to the shaping frame 22a. A string player aligns the bolt with the threaded hole 23d, and rotates the knob 23a in a certain direction. The bolt is screwed into the threaded hole 23d, and the cover plate 23c is pressed against the rigid plate 23b. As a result, the shaping frame 22a and the yoke 22b are connected to the trunk 21. If the knob 23a is rotated in the opposite direction, the bolt is taken off, and the cover plate 23c is unfastened from the rigid plate 23b. Accordingly, the shaping frame 22a and the yoke 22b are separated from the trunk 21. The coupling unit 24 is similar to the coupling unit 23, and includes a rigid plate 24a fixed to the trunk 21, a bolt 24b projecting from a knob and a cover plate rotatably supporting the bolt 24b. The cover plate 24c is fixed to the connecting plate 22c. A threaded hole 24d is also formed in the rigid plate 24a, and the bolt 24b is screwed into and out of the threaded hole 24d. Thus, the connecting plate 22c is fastened to and unfastened from the trunk 21 by means of the coupling unit 24. Turning to figures 5A and 5B, the coupling unit 25 includes a plate 25a, a bolt 25b, a knob 25c and a bottom portion 25d. The plate 25a is connected to the frame 22d, and a hole 25e is formed in the plate 25a. The hole 25e is slightly wider than the bolt 25b. The bolt 25b projects from the knob 25c. The trunk 21 has the bottom portion 25d, and a threaded hole 25f is formed in the bottom portion 25d. Alternatively, the threaded hole 25f may be formed in a plate, which is attached to the bottom portion 25d. The bolt 25b is screwed into and out of the threaded hole 25f. When the string player assembles the shaping frame 22a with the trunk 21, the string player pushes the plate 25a toward the bolt 25b so as to place the bolt 25b into the hole 25e. Then, the plate 25a is laminated on the bottom portion 25d. The string player turns the knob 25c, and fastens the plate 25a to the bottom portion 25d. When the string player separates the shaping frame 22a from the trunk 21, the string player loosens the bolt 25b with the knob 25c, and removes the plate 25a from the bottom portion 25d. The bolts 25b remains partially screwed into the bottom portion 25d. Thus, the shaping frame 22a is connected to and separated from the trunk 21 by means of the coupling unit 25. Turning back to figures 3 and 4, the electric double-bass 20 further comprises a peg box 27, four pegs 28, a scroll 29, a fingerboard 30 and a nut 31. In this instance, the peg box 27 is integral with the trunk 21, and the scroll 29 is inserted into the peg box 27. The pegs 28 are rotatably supported by the peg box 27, and each of the pegs 28 has a shaft, a worm gear, a knob and a worm wheel. The shaft laterally extends over the gap formed in the peg box 27, and the worm wheel is attached to the shaft. The knob is rotatably supported on the side surface of the peg box 27, and the worm gear is connected to the knob. The worm gear is meshed with the worm wheel. The knob is driven for rotation by a string player so as to rotate the shaft. Thus, the pegs 28 are identical in function with those of the acoustic double-bass. The fingerboard 30 is attached to the front surface of the trunk 21, and the nut 31 is embedded into the fingerboard in the proximity with the peg box 27. Thus, the peg box 27, the pegs 28, the scroll 29, the fingerboard 30 and the nut 31 imitate the appearance of the acoustic double-bass. The electric double-bass 20 further comprises a tail piece 32, four strings 33, a bridge 34, an end pin EP and a knob KN. The tail piece 32 is attached to the trunk 21, and is spaced from the fingerboard 30. The bridge 34 is provided on the front surface of the trunk 21, and is upright to the front surface of the trunk 21 between the fingerboard 30 and the tail piece 32. The four strings 33 are anchored to the tail piece 32, and are wound on the pegs 28. Thus, the four strings 33 are stretched substantially in parallel to one another over the fingerboard 30 and the exposed front surface of the trunk 21 between the associated pegs 28 and the tail piece 32. The nut 31 and bridge 34 give tension to the four strings 33. The strings for the acoustic double-bass are available for the electric double-bass 20. The strings 33 are less expandable. For this reason, the pegs 28 are driven for rotation by means of the worm gear and the worm wheel. The end pin EP downwardly projects from the trunk 21. The end pin EP is retractable into the trunk 21, and is positioned at an arbitrary position by means of the knob KN. The end pin EP keeps the trunk 21 over a floor. The electric double-bass 20 further comprises an electric sound generating system 35. The electric sound generating system 35 converts the vibrations of the strings 33 to an analog audio signal and, thereafter, generates electric tones on the basis of the analog audio signal. In this instance, the electric sound generating system 35 includes a pickup unit 35a and an electric circuit (not shown). The electric circuit is built in the trunk 21, and is connected to a sound system 35c. The pickup unit 35a is provided under the bridge 34, and is sandwiched between the bridge 34 and the trunk 21. The pickup unit 35a has two piezoelectric elements. Only one or more than two piezoelectric elements may be incorporated in the pickup unit 35a. The piezoelectric elements convert the vibrations of the strings 33 to analog detecting signals. The pick-up unit 35a is connected to the electric circuit, and the analog detecting signals are supplied from the pickup unit 35a to the electric circuit. The electric circuit carries out an equalization in the analog detecting signals so as to produce an audio signal. The audio signal represents a timbre close to that of the acoustic double-bass. The electric circuit is connected to the sound system 35c. A speaker unit 35d and a headphone 35e are incorporated in the sound system 35c. Although the electric circuit directly supplies the analog audio signal to the headphone 35e, the analog audio signal is firstly supplied to an appropriate amplifier 35f, and, thereafter, is supplied from the amplifier 35f to the speaker unit 35d. The electric tones are radiated from the speaker unit 35d and/ or the headphone 35e. Thus, the electric sound generating system 35 generates the audio signal from the vibrations of the strings 33, and the sound system 35c generates the electric tones like those of the acoustic double-bass. The electric double-bass 20 is disassembled as follows. First, the string player rotates the knob and, accordingly, the bolt 24b, and takes off. Then, the cover plate 24c is unfastened from the rigid plate 24a. The string player turns the connecting plate 22c around the pin 26, and folds the connecting plate 22c on the inner surface of the shaping frame 22a as shown in figure 6. Subsequently, the string player turns the knobs 23a and 25c, and loosens the bolts. The cover plates 23c are unfastened from the associated rigid plate 23b, and the plate 25a is separated from the bottom portion 25d. Thus, the framework 22 is released from the trunk 21. Finally, the yoke 22b is folded as shown in figure 7. The folded yoke 22b is desirable, because the string player accommodates the trunk 21 and the framework 22 in a narrow case. As will be understood, the framework 22 is detachable from the trunk 21, and the electric double-bass 20 is improved in the portability by virtue of the detachable framework 22. When the string player assembles the framework 22 and the trunk 21 together, the string player takes the above-described order backward, and connects the electric circuit to the sound system 35c. Then, the string player gets ready for playing the electric double-bass 20. While the string player is bowing, the strings 33 selectively vibrate, and the vibrations are converted to the analog detecting signals by means of the pickup unit 35a. The electric circuit regulates the volume balance, and makes the timbre like that of the acoustic tones. The electric circuit supplies the analog audio signal to the sound system 35c, and the sound system 35c generates the electric tones from the analog audio signal. If the string player wants to practice the electric double-bass 20 silently, the string player instructs the electric circuit to supply the analog audio signal only to the headphone 35e, and starts the bowing. Although the strings 33 are vibrating, the strings 33 faintly generate the acoustic tones. The string player can hear the electric tones through the headphone 35e without any disturbance to the neighborhood. When another analog audio signal is supplied to the electric circuit from the outside, the string player can practice ensemble together with another silent musical instrument and/ or a CD (Compact Disk) player. As will be appreciated from the foregoing description, the framework 22 is detachable from the trunk 21, and enhances the portability of the electric double-bass 20 according to the present invention. Second Embodiment An electric cello embodying the present invention largely comprises a trunk, a detachable framework, coupling units, strings, accessory parts and a sound generating system. A standard acoustic cello is smaller in size than the standard acoustic double-bass. Although the electric cello is different in dimensions from the electric double-bass, the electric cello is similar in structure to the electric double-bass. In this instance, the electric cello is as long as the acoustic cello, and the strings are shared between the electric cello and the acoustic cello. For this reason, the electric cello is not shown in the drawings. However, there are several differences between the electric cello and the electric double-bass 20. The standard acoustic cello is usually bowed by a string player who sits on a chair. This means that the electric cello is held in contact with the string player at different positions from those of the electric double-bass during the performance. For this reason, the framework of the electric cello has pads differently attached to a plate. The detachable frameworks according to the present invention are appreciated for the large-sized bowed stringed musical instruments of the violin family. However, the detachable framework is available for other members of the electric violin family such as an electric violin and an electric viola. The detachable framework permits a string player to carry the electric violin or the electric viola in a small case. Thus, the detachable framework is desirable for the other members of the electric violin family. In the above- described embodiments, the relatively thick base of the trunk 21, the framework 22 and the coupling units 23, 24 and 25 as a whole constitute a body without any resonator, and the relatively thin neck of the trunk 21 serves as a neck. The thick portion is corresponding to a stem. Although particular embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention. For example, the pickup unit 35a may be directly provided on or in the trunk 21, the bridge 34 or the fingerboard 30. The trunk 21 may be separable into more than one piece. The electric circuit may have an equalizer for producing the analog audio signal. The harmonics may be controlled for producing the analog audio signal. The coupling units 23, 24 and 25 are used for assembling the trunk and the framework together. In the above- described embodiments, the framework is connected to the trunk through the threaded engagement between the male screws and the female screws. The male screws and the female screws never set any limit on the present invention. A nipple and a socket may be used as another example of the coupling. Another example of the coupling is a wedge and a stopper. Wedges are formed at both end portions of the shaping frame 22a and at one end portion of the connecting plate 22c, and holes are formed in the trunk 21. Stoppers are provided in the holes, and are linked with appropriate buttons. Springs urge the wedges at all times. When the wedge is inserted into the hole, the wedge pushes the stopper along the oblique surface thereof against the spring, and the stopper is engaged with the back surface of the wedge. The stopper does not allow the wedge to move backward. When the string player pushes the button, the button evacuates the stopper from the back surface of the wedge, and the string player moves the wedge out of the hole. Another example of the coupling unit is a toggle joint. An electromagnetic clutch may be used as yet another example of the coupling unit. The pickup unit 35a electromagnetically produces the analog detecting signal from the vibrations of the strings 23. Another pickup unit may be implemented by a photo-couplers for producing the analog detecting signals representative of the vibrations of the strings 23. Yet another pickup unit may include coils so as to produce the analog detecting signals through the electromagnetic induction. The present invention may appertain to another kind of stringed musical instrument performed by a player through plucking. The sound system may be built in the trunk 21.
