Description

[Technical field]

[0001] The present invention relates to a stringed instrument holding device and a method for arranging one or more stringed instruments, in particular to a stringed instrument holding device suitable for holding in space a stringed instrument equipped with a stringed instrument excitation device, and to a method for arranging one or more stringed instruments equipped with a stringed instrument excitation device. [Background technology]

[0002] Generally, a stringed instrument has a sound box made up of a top plate (body plate), a back plate, and side plates, and a sound hole is formed in the top plate. Also, in a stringed instrument, a plate-shaped bridge base member is fixed to the top plate with adhesive, and a bridge is attached to the bridge base member, extending in a direction perpendicular to the longitudinal direction of the strings to support the strings.

[0003] Various stringed instrument excitation devices have been developed that use such stringed instruments to transmit vibrations from a vibration generating device that vibrates in response to a sound source signal to each string of the stringed instrument for automatic performance. Conventional stringed instrument excitation devices include those described in Patent Documents 1 and 2 below.

[0004] By using such a stringed instrument excitation device, it becomes possible to drive one or more stringed instruments with a sound source signal to perform an automatic performance. For example, in a string quartet performance, two violins, one viola, and one cello are used. Among these four stringed instruments, the cello is placed on the floor with a part of it touching the floor, while the other three stringed instruments are held at a predetermined angle in space during normal performance. In addition, the cello is held at a predetermined angle while a part of it touches the floor.

[0005] When a stringed instrument or instruments are played by a specific performer, the generated sound is recorded by a device having a recording function connected to one or more microphones, and the recorded sound source signal or sound source data is used to drive a stringed instrument excitation device to automatically play back the sound on one or more stringed instruments. In this case, the holding angle of each of the stringed instruments can be set to the same as the holding angle at the time of recording, so that the same musical sound can be generated as when the stringed instruments were recorded. That is, when recording, a performer has a certain habit or habit when holding a stringed instrument, and the holding angle is different between one performer and another performer, even if the stringed instrument is the same type. In addition, each performer has a different height, and the height of the stringed instrument itself from the floor is different depending on the unique way that the performer holds the stringed instrument. Usually, the microphone or microphones used for recording are placed at a certain height from the floor, so the recorded sound is affected by the height of the stringed instrument at the time of recording, i.e., the relative height to the microphone height. In the case of string instruments, it has been reported that sound does not spread uniformly into space from the point of friction of the strings, but rather the direction and intensity of sound emission change depending on the frequency due to the vibration characteristics of the body (see the proceedings containing the presentation by Maki Masahiro of Aichi Shukutoku University titled "Measurement of spatial radiation characteristics of musical instrument performance sounds: player's skill level and characteristics of famous instruments" at the 60th Japan Federation of Automatic Control Associations Conference (November 10-12, 2017, Tokyo)).

[0006] In particular, when multiple stringed instruments are used for recording, such as a quartet performance, the spatial arrangement of each stringed instrument, the height of each stringed instrument from the floor, and the inclination angle of each stringed instrument are important. Here, the inclination angle refers to the inclination angle at which the stringed instrument rotates around at least one of the X, Y, and Z directions, where the X direction is the longitudinal direction of the stringed instrument or the direction in which the strings of the stringed instrument extend, the Y direction is the direction in which the multiple strings of the stringed instrument are lined up, and the Z direction is the direction perpendicular to the X and Y directions. FIG. 24 is a photograph showing a solo violinist playing the violin in a standing position as a reference example. FIG. 25 is a photograph showing four players of a string quartet playing their respective instruments in a seated position as a reference example. FIG. 26 is a photograph showing another example of four players of a string quartet playing their respective instruments in a seated position as a reference example. The positions of the cellist and the viola player are different between FIG. 25 and FIG. 26. Also, we can see that the height of the instrument from the floor is naturally different when playing standing and when playing sitting. Also, we can see that each player plays the same violin in a unique posture, that is, tilted at a certain angle around the X direction, Y direction, and Z direction.

[0007] In this way, when using a stringed instrument excitation device to drive a stringed instrument for automatic playback, it is important to reproduce the inclination angle of the stringed instrument when the sound source signal or sound source data to be supplied to the stringed instrument excitation device was recorded, and the height of the stringed instrument from the floor and its arrangement in space at the time of recording are also important. Furthermore, when using multiple stringed instruments for automatic playback, it is important to reproduce the inclination angle and height of each stringed instrument as well as their arrangement in space.

[0008] Therefore, one object of the present invention is to provide a stringed instrument holding device that allows at least one of the inclination angles of the stringed instrument rotating around at least one of the height, X-direction, Y-direction, and Z-direction in the space of the stringed instrument during automatic playback to be set in the same manner as during recording. Another object of the present invention is to provide a method for arranging a single or multiple stringed instruments that allows the arrangement of a single or multiple stringed instruments in the space during automatic playback to be set in the same manner as during recording. Note that the arrangement of the stringed instruments, the postures, and the mutual arrangement relationships in the case of multiple stringed instruments shown in Figures 24 to 26 are examples or typical examples, and each player does not always maintain these positions and postures during performance. Rather, the postures of each player may change dynamically during performance. Therefore, one object of the present invention is to set the inclination angle of the stringed instrument during playback by freely following the change even if the posture of the stringed instrument changes from the standard or typical posture during recording of the performance. [Prior art documents] [Non-patent literature]

[0009] [Patent Document 1] Patent No. 7098219 Figures 1 to 11 Figures 14 to 23 [Patent Document 2] JP 2022-61728 A Figure 3 Summary of the Invention [Problem to be solved by the invention]

[0010] Various methods have been proposed for configurations in which a vibrating device is vibrated by a sound source signal created by recording a performer playing a stringed instrument, and the vibrations are then transmitted to the stringed instrument to perform it automatically. However, no idea has been given of the height and tilt angle at which the performer held the stringed instrument during recording - in other words, the first challenge - to grasp the tilt angle at which the stringed instrument rotates around at least one of the X, Y, and Z directions, and then to set the height and tilt angle of the stringed instrument at the playback site to the same as during recording, and the need for a configuration to hold the stringed instrument at a specified height and tilt has not been recognized.

[0011] As a second problem, the idea or necessity of being able to set the spatial arrangement of a single or multiple string instruments during automatic playback in the same way as during recording was not recognized. [Means for solving the problem]

[0012] In order to solve the first problem mentioned above, the present invention uses a holder that holds the body of a stringed instrument in space and a stand that can be placed on the floor and has a pole portion that can be extended to any height, and has a tilt angle setting means, located between the stand and the holder or provided on the holder itself, that can arbitrarily set the tilt angle of the stringed instrument.

[0014] In addition, when the longitudinal direction of the stringed instrument or the extension direction of the strings of the stringed instrument is defined as the X direction, the direction in which the strings of the stringed instrument are arranged is defined as the Y direction, and the direction perpendicular to the X direction and the Y direction is defined as the Z direction, the inclination angle setting means is capable of setting an inclination angle at which the stringed instrument rotates around at least one of the X direction, the Y direction, and the Z direction, which is a preferred embodiment of the present invention that solves the first problem. Furthermore, in a preferred embodiment of the present invention that solves the first problem, the inclination angle setting means is a camera or other optical device pan head and has a means for preventing a sudden change in the inclination angle. Furthermore, in a preferred embodiment of the present invention that solves the first problem, the combination of the stand and the inclination angle setting means is a camera or other optical device tripod having a pan head. In a preferred embodiment of the present invention that solves the first problem, the holder has an arm assembly for holding the stringed instrument, a first holding part for connecting one end of the arm assembly to one end of the stringed instrument, and a second holding part for connecting the other end of the arm assembly to the other end of the stringed instrument. Furthermore, in a preferred embodiment of the present invention which solves the first problem, the arm assembly has a main arm which extends substantially linearly, or extends in a certain curved line, or has two or more parts which extend substantially linearly and a bent part provided between them, and the longitudinal direction of the stringed instrument or the extension direction of the strings of the stringed instrument is set as an X-direction, and as a means for setting a rotation angle of the stringed instrument centered on the X-direction, the arm has a means for setting an angle at which the main arm rotates about the longitudinal direction of at least a part of the main arm and fixing the angle at a desired angle. Furthermore, in a preferred embodiment of the present invention which solves the first problem, the means for setting an angle at which the main arm rotates and fixing the angle at a desired angle is a combination of a cylindrical part rotatably attached to the outer periphery of the main arm and a rotation angle fixing means for fixing the cylindrical part to the main arm.Further, in a preferred embodiment of the present invention that solves the first problem, the instrument has a sub-arm that engages with the main arm, extends parallel to the main arm, and has a portion that engages with the stand, and a connecting portion that connects the sub-arm and the stand has a means that can control the angle at which the stringed instrument rotates around a direction perpendicular to the X-direction and fix it at a desired angle. Further, in a preferred embodiment of the present invention that solves the first problem, the first holding portion has a portion that is connected to the arm assembly, two recesses that can respectively engage with at least two rod-shaped members attached to the stringed instrument, and an elastic member provided between the two recesses that can change the distance between the two recesses. Further, in a preferred embodiment of the present invention that solves the first problem, the second holding portion has a portion that is connected to the arm assembly, and an arc-shaped connecting arm that can engage with the neck of the stringed instrument. Further, in a preferred embodiment of the present invention that solves the first problem, the arc-shaped connecting arm can be opened and closed, and in a closed state, surrounds the neck with a closed loop. Further, in a preferred embodiment of the present invention that solves the first problem, the stand has a height adjustable portion. Furthermore, in a preferred embodiment of the present invention which solves the first problem, the stand is a camera stand, a microphone stand, or an improvement of either of these. Furthermore, in a preferred embodiment of the present invention which solves the first problem, the arm assembly is made of wood. Furthermore, in a preferred embodiment of the present invention which solves the first problem, the cylindrical portion is made of synthetic resin.

[0015] In addition, in order to solve the second problem described above, i.e., to enable the spatial arrangement of one or more string instruments during automatic playback to be set to the same as that at the time of recording, the present invention is configured so that when a string instrument excitation device uses the sound source signal / sound source data of the recorded musical sound to drive one or more string instruments at the playback site for playback, the single or multiple string instruments at the playback site are arranged in positions similar to the positions in three-dimensional space of the string instruments played by the performer at the time of recording.

[0016] In other words, according to the present invention which solves the second problem, there is provided a method for arranging one or more stringed instruments, which involves recording sound source signals / sound source data of musical sounds when one or more stringed instruments are played by a performer, and using the sound source signals / sound source data of the recorded musical sounds to drive one or more stringed instruments at the playback site using a stringed instrument excitation device to play them, and arranging the one or more stringed instruments at the playback site in positions similar to the positions in three-dimensional space of the stringed instruments played by the performer at the time of recording.

[0017] In a preferred embodiment of the present invention for solving the second problem, the position of the stringed instrument in three-dimensional space at the playback site is determined using coordinate information indicating the position of the stringed instrument or instruments at the time of recording. Furthermore, in a preferred embodiment of the present invention for solving the second problem, the height of the stringed instrument at the playback site and the tilt angle at which the stringed instrument rotates are set by the stringed instrument holding device of the present invention for solving the first problem. Effect of the Invention

[0018] According to the present invention, which solves the first problem, various stringed instruments can be held at any height and tilt angle, and when an automatic performance is performed by a stringed instrument excitation device, the stringed instrument can be held by reproducing the tilt angle of the stringed instrument at the time of recording. Also, according to the present invention, attachment and detachment are easy, and the attachment and detachment time is short, so that the stringed instrument can be easily held in a space and released from the held state. Furthermore, according to the present invention, the height and tilt angle of the stringed instrument at the time of playback are set to the same height and tilt angle of the stringed instrument at the time of recording, i.e., the way of holding the stringed instrument, and therefore, with the added audiovisual effect, the listener can be given a sense of realism of a live performance.

[0019] According to the present invention, which solves the second problem, the spatial arrangement of one or more stringed instruments during automatic playback can be set to the same as that during recording, so that when a stringed instrument excitation device uses the sound source signal / sound source data of a recorded musical tone to drive one or more stringed instruments at the playback site to play the musical tone, the one or more stringed instruments at the playback site can be arranged in the same three-dimensional space as the stringed instruments played by the performer at the time of recording. Furthermore, according to the present invention, the height and tilt angle of the stringed instruments at the time of playback, and in the case of multiple stringed instruments, their mutual arrangement relationship is set to the same as that of the stringed instruments at the time of recording, and therefore, with the added audiovisual effect, the listener can be given the sense of realism of a live performance.

[0021] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing a state in which a violin 10, which is a stringed instrument, is held substantially horizontally according to a first embodiment of the present invention. Here, a violin is shown as the stringed instrument 10, but it may be a viola or other similar stringed instruments. The violin 10 has a body 12, a neck 14, and a chin rest 16 attached to the body 12 by attachments 18A, 18B (see FIG. 22). In this specification and drawings, a view of the instrument seen from the neck side is referred to as a front view, a view seen from the tailpiece side is referred to as a back view, a view seen from the right side of the front view seen from the neck side is referred to as a right side view, and a view seen from the left side of the front view is referred to as a left side view.

[0022] The body 12 of the violin 10, which is a stringed instrument, is held by a holder 20. The holder 20 has an arm assembly 20A (see FIG. 4), a first holding portion 28, and a second holding portion 29. The arm assembly 20A has an arm 22, a cylindrical portion 26 rotatably attached to the arm 22 approximately in the center of the arm 22 in the longitudinal direction, and an attachment screw portion 27 fixed below the cylindrical portion 26. The first holding portion 28 is attached to the rear end of the arm 22, and the second holding portion 29 is attached to the front end of the arm 22.

[0023] The holder 20 is supported by a stand 30 placed on a floor or the like (not shown) and is positioned in space. The stand 30 is called a "straight stand", but in this specification, it is also simply called a "stand". The stand 30 has a base 32 placed on a floor or the like, a first pipe 34 fixed to the center of the base 32 and extending upward, a telescopic adjustment part 38 attached near the upper end of the first pipe 34, a second pipe 36 extending upward from the telescopic adjustment part 38, and a mounting screw part 36A attached to the upper end of the second pipe 36 (see FIG. 2A). An improved pan head 39A is attached to the upper end of the mounting screw part 36A. Note that if the size or standard of the mounting screw part 36A (male screw) of the stand 30 does not match the size or standard of the tripod fixing screw part (female screw) (not shown) provided at the bottom of the pan head 39 described later, a conversion screw part (not shown) can be used.

[0024] FIG. 2A is an exploded perspective view showing only a part of the arm assembly 20A and the stand 30 in the first embodiment shown in FIG. 1, and an improved pan head 39A provided between the arm assembly 20A and the stand 30. Here, the improved pan head 39A will be described. The pan head 39 itself has been sold and used for cameras, and what is used here is called a "ball-type free pan head" or a "microball pan head", but in this specification, it is simply called a "pan head". The shape of the pan head varies depending on the manufacturer, but here, one representative example will be described. As shown in FIG. 23, the pan head 39 has a base 39-1, a spherical part (microball) (not shown) that can rotate freely inside the base 39-1, a spherical part fixing screw 39-2 attached to the base 39-1, a knob part 39-3 of the spherical part fixing screw 39-2, a male screw part 39-4 attached to a part of the spherical part and extending upward, and a fixing ring part 39-5 attached to the male screw part 39-4. The sphere can freely rotate within a sphere holder (not shown) provided inside the base 39-1, but when an operator operates the knob 39-3 to rotate the sphere fixing screw 39-2 clockwise, the sphere holder fixes the sphere so that it cannot rotate. On the other hand, when the sphere fixing screw 39-2 is rotated counterclockwise, the sphere holder makes the sphere rotatable. The fixing ring 39-5 has a female screw (not shown) that screws into the male screw 39-4, and the male screw 39-4, which screws into the female screw of a camera or other optical device supported by the pan head 39, is pressed against the optical device by the rotation of the male screw 39-4, thereby fixing it.

[0025] In addition, a notch of a predetermined width is provided on the left side of the portion of the base 39-1 where the upper diameter is smaller than the lower diameter, and when the male screw portion 39-4 is operated so as to fall to the left side in the figure, the male screw portion 39-4 can be rotated 45 degrees to the left from the upward extension state shown in the figure. When the ball portion fixing screw 39-2 is rotated leftward to allow the ball portion to rotate freely, the male screw portion 39-4 can rotate 360 ​​degrees with respect to the base 39-1 and can be tilted freely. In other words, when the longitudinal direction of the stringed instrument 10 or the extension direction of the strings of the stringed instrument 10 is defined as the X direction, the direction in which the multiple strings of the stringed instrument 10 are arranged is defined as the Y direction, and the direction perpendicular to the X direction and the Y direction is defined as the Z direction, the tilt angle at which the stringed instrument 10 rotates around all of the X direction, Y direction, and Z direction can be set by the pan head 39. A female screw (not shown) is provided on the bottom of the base 39-1.

[0026] The conventional pan head 39 is improved and used as the improved pan head 39A. In the improved pan head 39A, the fixing ring portion 39-5 is not used and is removed in advance. In the improved pan head 39A of the present invention, as shown in FIG. 2A, an elastic cover portion 39A7 is provided to cover a portion of the upper portion of the base portion 39-1 whose aperture is smaller than that of the lower portion and a portion of the male screw portion 39-4 at the upper portion. In FIG. 2A, a portion of the improved pan head 39A is shown as a partial cross-sectional view to show the internal structure. In addition, a tube portion 39A6 is provided around a portion below the exposed portion of the male screw portion 39-4, and the elastic cover portion 39A7 is configured to cover the outer periphery of the tube portion 39A6. The elastic cover portion 39A7 functions as follows. In other words, when the spherical portion of improved pan head 39A is freely rotatable, holder 20 supported on the top and / or stringed instrument 10 held by holder 20 may rotate inadvertently and / or suddenly in either direction, and the force of the rotation may cause an impact to be applied to stringed instrument 10, or in the worst case, stringed instrument 10 may become detached from holder 20 and fall. Therefore, in order to prevent such inadvertent or sudden rotation, elastic cover portion 39A7 is provided which functions as a means for preventing abrupt changes in the tilt angle.

[0027] That is, the lower part of the elastic cover part 39A7 covers the part of the base part 39-1 with a smaller diameter and is fixed thereto with an adhesive, the upper part covers the outer periphery of the tube part 39A6 and is fixed thereto with an adhesive, and the inner periphery of the tube part 39A6 covers a part of the male screw part 39-4 and is fixed thereto, so that the elastic force of the elastic cover part 39A7 prevents the male screw part 39-4 from being inclined suddenly. The elastic cover part 39A7 is made of rubber or silicone rubber and has a thickness of about 1 mm. Furthermore, the elastic cover part 39A7 is cylindrical in shape so as to cover the outer periphery of the tube part 39A6 and the part of the upper part of the base part 39-1 with a smaller diameter than the lower part, and the size of the elastic cover part 39A7 is set so that the inner diameter of the elastic cover part 39A7 is the same as the outer shape of the tube part 39A6 or smaller than the outer shape of the tube part 39A6.

[0028] FIG. 2B is a perspective view showing another example 39B of the improved pan head 39A shown in FIG. 2A. The improved pan head 39B in FIG. 2B is different from the improved pan head 39A shown in FIG. 2A in the following points. That is, the improved pan head 39B uses the fixing ring part 39-5 of the conventional pan head 39 shown in FIG. 23, and uses an elastic cover part 39B7 that covers from the outer periphery of the fixing ring part 39-5 to the part with the small diameter of the base part 39-1 instead of the elastic cover part 39A7 shown in FIG. 2A. In the improved pan head 39B, since the elastic cover part 39B7 is fixed to the outer periphery of the fixing ring part 39-5, it is not necessary to use the tube part 39A6 as in the improved pan head 39A. The inner diameter of the elastic cover part 39B7 is designed to match the part with the smallest outer diameter among the parts covered by the elastic cover part 39B7. In the first embodiment, a modified spherical head is used, but other types of heads can be used, and various types of tripods with heads can be used in place of the modified head and stand combination of the first embodiment.

[0029] The holder 20, the whole of which is shown in Figs. 3 and 4 described later, is connected to the stand 30 as follows. That is, the screw receiving portion 27 of the arm assembly 20A (see Fig. 4) has a female screw (not shown) extending upward from its lower portion in the center inside, and is screwed into a male screw portion 39A-4 of the improved pan head 39A. The telescopic adjustment portion 38 attached near the upper end of the first pipe 34 is rotatable with respect to the first pipe 34 and the second pipe 36. By rotating in a certain direction, the second pipe 36 is in a loose state in which it can move up and down with respect to the first pipe 34, and by rotating in the opposite direction to the above-mentioned certain direction, the second pipe 36 is in a tightened state in which it cannot move up and down with respect to the first pipe 34 and is fixed. By operating this telescopic adjustment portion 38, the height of the mounting screw portion 27 of the holder 20 from the floor can be adjusted, and when the holder 20 supports the body 12 of the violin 10, which is a stringed instrument, the height of the violin 10 from the floor can be freely adjusted. That is, the combination of the first pipe 34, the second pipe 36 and the telescopic adjustment part 38 constitutes an extendable pole part.

[0030] In the first embodiment, a combination of the improved pan heads 39A, 39B and the stand 30 is used, but instead of this combination, a tripod with a pan head for a camera or other optical equipment can be used.

[0031] Here, the height of the violin 10 from the floor is the height of the upper surface of the chin rest 16 for convenience. Therefore, for example, if a player who is 178 cm tall stands on the floor and the height of the lower part of the player's chin from the floor is 160 cm, the height of the violin 10 from the floor is 160 cm. Since players have different heights and different heights of the lower part of their chins from the floor, it is useful to know in advance the height of the stringed instrument played by each player at the time of recording, that is, the height of the upper surface of the chin rest 16 in this case, in order to set the height of the stringed instrument 10 at the time of automatic playback later. It is considered that it is often difficult to actually measure the height of the stringed instrument played by each player at the time of recording. In such cases, information on the height of each player is obtained, or if there are photos or videos taken at the time of recording, they are used to estimate the height. As shown in the above-mentioned Figures 25 and 26, when a player plays while sitting, the height of the violin 10 from the floor is several tens of centimeters lower than when the player is standing, and is, for example, 110 cm. If recording information is difficult to obtain, a typical arrangement, for example for a string quartet, can be used.

[0032] Fig. 3 is a perspective view showing only the holder 20 in the first embodiment shown in Fig. 1, and Fig. 4 is an exploded perspective view showing only the holder 20 shown in Fig. 1 and Fig. 3. The arm 22 is slightly bent near the right end of the cylindrical portion 26 in Fig. 3 and Fig. 4, and generally extends linearly from the left end in the figures on the first holding portion 28 side to the right end of the cylindrical portion 26, and is bent so as to be slightly raised upward in the figures from the right end of the cylindrical portion 26 to the right end in the figures on the second holding portion 29 side. This bending occurs because the second holding portion 29 is not separated from the neck 14 of the stringed instrument 10 but is located near the neck 14.

[0033] Next, the first holding part 28 will be described. The first holding part 28 detachably connects and fixes one end of the arm 22 to the stringed instrument body 12 by utilizing the attachments 18A and 18B of the chin rest 16 shown in Figs. 1, 12 and 22. On the other hand, the second holding part 29 detachably connects and fixes one end of the arm 22 to the neck 14 shown in Fig. 1. Here, the structure and operation of the first holding part 28 will be described. Fig. 5 is a rear view of the first holding part 28, Fig. 6 is a top view of the first holding part 28, and Fig. 7 is a left side view showing the engagement between the first holding part 28 and the left end of the arm 22. The first holding part 28 has a main body part 28D connected and fixed to the left end of the arm 22, an elastic member part 28A connected to the upper end of the main body part 28D, and plate-shaped parts 28B1, 28B2, 28C1, and 28C2 connected to both left and right ends of the elastic member part 28A, and the plate-shaped parts 28B1 and 28B2 face each other, and the plate-shaped parts 28C1 and 28C2 also face each other. With this configuration, two recesses 28G1 and 28G2 formed by two opposing parts at the left and right ends of the elastic member part 28A are for engaging with the attachments 18A and 18B of the chin rest 16 shown in Fig. 22. The main body part 28D and the elastic member part 28A are connected to each other by two pins 28E1 and 28E2 shown by dotted lines in Fig. 5. That is, approximately one-quarter of the longitudinal length of the two pins 28E1, 28E2 is pre-embedded and fixed in the main body portion 28D, and the remaining approximately three-quarters exposed are inserted into the elastic member portion 28A when interconnected.

[0034] The main body 28D is located below the elastic member 28A, and as shown in FIG. 7, a hole 28D5 is provided below the main body 28D in the thickness direction, and a screw 28D4 passes through the main body 28D via the hole 28D5 and is screwed into the left end of the arm 22. That is, the main body 28D is fixed to the arm 22 by screwing the screw 28D4 into the female thread 22-2 provided at the left end of the arm 22. The screw head of the screw 28D4 is indicated by 28D1, and the screw 28D4 passes through the center hole of the fixed base 28D2 of the positioning pin 28D3. The positioning pin 28D3 extends to the right in FIG. 7 from the fixed base 28D2 of the positioning pin 28D3. The positioning pin 28D3 is inserted into the pin receiving hole 22-1 provided at the left end of the arm 22.

[0035] 8 and 9 are diagrams showing how to attach and detach the first holding part 28 to and from the attachments 18A and 18B of the chin rest 16. When an operator holds the left and right ends of the first holding part 28 with, for example, the thumb and index finger of the right hand and applies a compressive force, the first holding part 28 is bent in an "L" shape around the approximate center of the elastic member part 28A, and the distance between the left and right ends of the first holding part 28 becomes shorter. When this distance becomes sufficiently short, the recesses 28G1 and 28G2 formed by the plate-shaped parts 28B1, 28B2, 28C1 and 28C2 are brought to a position where they can engage with the attachments 18A and 18B of the chin rest 16, and when the compressive force is released here, the recesses 28G1 and 28G2 engage with the attachments 18A and 18B of the chin rest 16, and the first holding part 28 is held by the attachments 18A and 18B. When removing first holding portion 28 from attachments 18A, 18B of chin rest 16, the operator holds the left and right ends of first holding portion 28 with, for example, the thumb and index finger of the right hand in the same manner as above, and applies a compressive force, causing elastic member portion 28A to bend in an "L" shape around the approximate center, shortening the distance between the left and right ends of first holding portion 28. When this distance becomes sufficiently short, recesses 28G1, 28G2 are released from attachments 18A, 18B of chin rest 16.

[0036] As shown in Figs. 3 and 4, the second holding part 29 has a main body part 29A connected and fixed to the right end of the arm 22, and an arc-shaped connecting arm 29C extending from the upper left of the main body part 29A in the figure. Fig. 10 is a rear view of the second holding part 29, and Fig. 11 is a right side view showing the engagement state of the second holding part 29 and the arm 22. The main body part 29A is made of rubber or silicone rubber, and the arc-shaped connecting arm 29C is made of synthetic resin and is flexible, with a thin plate-like member extending in an arc shape. The right end of the arm 22 in the figure is fixed by fitting into a hole 29B provided in the main body part 29A. A permanent magnet piece 29D is fixed to the upper part of the right side surface of the main body part 29A in the figure, while a permanent magnet piece 29E is fixed to the inside near the tip of the arc-shaped connecting arm 29C.

[0037] Before the arm 22 is attached to the stringed instrument body 12, the permanent magnet piece 29E is separated from the permanent magnet piece 29D, and the arc-shaped connecting arm 29C is in an open state. When the right end of the arm 22 is attached to the neck 14 by the second holding part 29, the arc-shaped connecting arm 29C is arranged to go around the neck 14, and then the permanent magnet piece 29E is brought close to the permanent magnet piece 29D so that the two are connected by magnetic force. Conversely, when removing the arm 22, the permanent magnet piece 29E is operated with a finger or the like so as to be pulled away from the permanent magnet piece 29D. In this way, the arc-shaped connecting arm 29C can be in a closed state or an open state by attaching and detaching the permanent magnet pieces 29E and 29D to each other. That is, the arc-shaped connecting arm 29C can be opened and closed, and in the closed state, it surrounds the neck 14 with a closed loop.

[0038] Here, the materials of each part constituting the stringed instrument holding device of the present invention will be described. The arm 22 constituting the arm assembly 20A of the holding tool 20 is made of wood. The reason for using wood is to avoid damaging the delicate stringed instrument 10. If metal or hard synthetic resin is used, the surface of the arm 22 can be covered with soft cloth, leather, synthetic resin sheet, etc. The cylindrical part 26 arranged in the approximate center of the arm 22 is made of hard synthetic resin, but its surface can be covered with soft cloth, leather, synthetic resin sheet, etc. The plate-shaped parts 28B1, 28B2, 28C1, and 28C2 of the first holding part 28 are made of hard synthetic resin. The main body part 28D of the first holding part 28 can be made of an elastic material like the elastic member part 28A. The elastic member part 28A and the main body part 28D can be made of rubber or silicone rubber.

[0039] The first embodiment of the present invention is used as follows. The following description will be given by taking as an example a case where the stringed instrument holding device of the present invention as the first embodiment holds a violin. As shown in FIG. 1, a stand 30 is placed on the floor, and the holder 20 is supported on the upper part of the stand 30 via an improved pan head 39A. At this time, the knob 39-3 of the pan head 39A is operated so that the longitudinal direction of the male screw part 39-4 shown in FIG. 2A is fixed in a substantially vertical state, that is, in a state parallel to the longitudinal direction of the stand 30. In this state, the violin 10 is held in space by the first holding part 28 and the second holding part 29 of the holder 20.

[0040] In this state, the violin 10 is arranged in space, that is, positioned. If the violin 10 is the first violin at the left end in FIG. 25, the XYZ coordinates, which are the three-dimensional coordinate information of the position under the chin of the leftmost violinist shown in FIG. 25, are grasped in consideration of the arrangement relationship with the other instruments, and the chin rest 16 of the violin 10 is positioned in space using this information. Note that the three-dimensional coordinate information referred to here does not have to be absolute, and may be relative coordinate information to the extent that the relative positions of multiple stringed instruments are grasped. For this positioning, the position of the stand 30 on the floor is selected, and then the height of the upper part of the chin rest 16 is set using the height adjustment function of the stand 30. Note that the order of positioning the stand 30 on the floor and adjusting the height may be reversed. Next, the knob 39-3 of the improved pan head 39A is operated to adjust the tilt angle of the body 12 of the violin 10 to set it to the same as that during recording shown in FIG. 25. That is, by operating knob 39-3, the spherical portion of improved pan head 39A is made freely rotatable, and the tilt angle and rotation angle about the Z axis of body 12 of violin 10 are adjusted. The tilt angle and rotation angle about the Z axis of body 12 of violin 10 can also be set before positioning stand 30 on the floor and adjusting its height as described above.

[0041] Next, a second embodiment of the present invention will be described. Fig. 12 is a right side view showing the second embodiment. The same reference symbols are used for the common parts between the second embodiment and the first embodiment, and the description thereof will be omitted. In the second embodiment, a holder 21 is used as a part corresponding to the holder 20 in the first embodiment, and the holder 21 has an arm assembly 21A (see Fig. 14), a main arm 22 which is one of the components of the arm assembly 21A, and a first holder 28 and a second holder 29 attached to both ends thereof, respectively. The arm assembly 21A is held in space by a stand 30A.

[0042] FIG. 13 is a perspective view showing only the holder 21, and FIG. 14 is an exploded perspective view showing only the holder 21. The arm assembly 21A of the holder 21 has a main arm 22, a sub-arm 23 located below the main arm 22 and substantially parallel to a part of the main arm 22, a first cylindrical portion 26X constituting a joint for joining the main arm 22 and the sub-arm 23, a second cylindrical portion 25, and a connecting portion 27A interconnecting the first cylindrical portion 26X and the second cylindrical portion 25. The main arm 22 has the same configuration as the arm 22 in the first embodiment, but only the name has been changed. As described later, the first cylindrical portion 26X is rotatable with respect to the main arm 22 and is configured to be fixed at a predetermined rotation angle. The function of adjusting and fixing this rotation angle will be described later. The sub-arm 23 is supported by a stand 30A, the configuration of which will be described later. The first cylindrical portion 26X, the connecting portion 27A, and the second cylindrical portion 25 are connected and fixed to each other by an adhesive. Therefore, when the first cylindrical portion 26X rotates relative to the main arm 22, the second cylindrical portion 25 connected to the first cylindrical portion 26X via the connecting portion 27A also rotates. Since the inner circumference of the second cylindrical portion 25 is adhesively fixed to the outer circumference of the sub-arm 23, the rotation of the second cylindrical portion 25 causes the sub-arm 23 to rotate about the axis of the arm 22.

[0043] 15 is a partial perspective view showing a state before a part of the arm assembly 21A of the holder 21 in the second embodiment is engaged with the swing-type stand 30A. The swing-type stand 30A is referred to as the stand 30A for convenience. The sub-arm 23 of the arm assembly 21A is inserted into the through-hole 37A of the sub-arm holder 37 at the upper part of the stand 30A, as shown by the dotted line with an arrow in the figure. The sub-arm holder 37 has a fastening screw 37B, and when the fastening screw 37B is fastened with the sub-arm 23 inserted into the through-hole 37A, the sub-arm 23 is fixed to the through-hole 37A. The lower part of the sub-arm holder has two plate parts as a stand connection part 37E, and a plate part (not shown) at the upper part of the stand 30A is sandwiched in the space between them. The stand plate sandwiched between the two plates as the stand connection part 37E is fixed by tightening the fastening screw 37D shown in Fig. 12, and thus the sub-arm holder 37 is fixed to the stand 30A. In Fig. 15, the reference numeral 37C denotes a screw fastening part on the opposite side to the fastening screw 37D shown in Fig. 12.

[0044] The first cylindrical portion 26X is rotatable with respect to the main arm 22, but the inner circumference of the first cylindrical portion 26X engages with the outer circumference of the main arm 22 with a predetermined friction coefficient. In order to achieve such engagement with the friction coefficient, a thin tape such as a cloth tape (not shown) is interposed between the inner circumference of the first cylindrical portion 26X and the outer circumference of the main arm 22. The first cylindrical portion 26X rotates the main arm 22 about its longitudinal axis, thereby setting the left-right tilt angle of the stringed instrument 10, i.e., the rotation angle about the X-axis, and there are various methods for this.

[0045] 16 to 21 are diagrams showing three types of methods for setting the rotation angle. Three modes of the first cylindrical portion indicated by reference symbol 26X in FIG. 13 and FIG. 14 are indicated by reference symbols 26A, 26B, and 26C, respectively. FIG. 16 is a side view showing a part of the main arm 22 and the first cylindrical portion 26A attached thereto, and FIG. 17 is a cross-sectional view taken along line XVII-XVII in FIG. 16. In FIG. 18 and FIG. 20 described later, the internal structure may be indicated by dotted lines. The first cylindrical portion 26A is provided with a cutout portion 26A1 that can be adjusted in three stages, and the rotation angle can be set to any three stages (0 degrees, 30 degrees, and 45 degrees in the illustrated example). That is, as shown in FIG. 17, the tip of the pin 26A2 is adhesively fixed to the through hole 22A of the main arm 22, and when the approximate center of the pin 26A2 is inserted into the through hole of the cutout portion 26A1 at 0 degrees in the figure, the inclination angle is set to 0 degrees. From this state, for example, to change the inclination angle to 30 degrees, move the main arm 22 rightward in FIG. 16 relative to the fixed first cylindrical portion 26A so that the approximate center of the pin 26A2 is located at the portion of the notch 26A1 that extends in the vertical direction in FIG. 16, and then rotate the main arm 22 to the right end of the portion of the notch 26A1 that extends in the horizontal direction in FIG. 16 and is indicated as "30". Next, move the main arm 22 leftward in FIG. In this way, the desired inclination angle can be set by operating the main arm 22 leftward and rightward and rotating it relative to the fixed first cylindrical portion 26A.

[0046] FIG. 18 is a side view showing a part of the main arm 22 and the first cylindrical portion 26B attached thereto, and FIG. 19 is a cross-sectional view taken along line XIX-XIX in FIG. 18. The first cylindrical portion 26B is provided with one through hole 26B1, and three recesses 22B1, 22B2, and 22B3 that can be adjusted to three levels are provided near the outer periphery of the main arm 22, so that the rotation angle can be set to any three levels (0 degrees, 30 degrees, and 45 degrees in the illustrated example). That is, when the screw 26B3 is inserted into the recess 22B1 at 0 degrees in the figure through the through hole 26B1 of the main arm 22, it is set and fixed at the desired angle (0 degrees in this case). The screw head of the screw 26B3 is indicated by the symbol 26B2. Note that the through hole 26B1 and the recess 22B1 are shown overlapping in FIG. 18.

[0047] Fig. 20 is a side view showing a part of the main arm 22 and the first cylindrical part 26C attached thereto, and Fig. 21 is a cross-sectional view taken along line XXI-XXI in Fig. 20. The first cylindrical part 26C is provided with one through hole 26C1 that can be adjusted steplessly, and the rotation angle can be set arbitrarily. That is, when a screw 26C3 is inserted into a recess 22C3 provided on the outer periphery of the main arm 22 through the through hole 26C1 and screwed in, that is, when the screw 26C3 is tightened and its tip is pressed against the bottom of the recess 22C3 of the main arm 22, the desired angle is set and fixed. The screw head of the screw 26C3 is indicated by the symbol 26C2.

[0048] The second embodiment is used as follows. The parts common to the first embodiment are omitted, and the differences are mainly described. The stringed instrument 10 is supported by the arm assembly 21A of the holder 21, and the arm assembly 21A is supported by the stand 30A, and the base 32 of the stand 30A is positioned at an appropriate position (setting of XY coordinates). At this time, the left-right direction of the stringed instrument 10 and the inclination of the stringed instrument in the longitudinal direction relative to the left-right direction of the playback site are also adjusted. Next, the telescopic adjustment unit 38 of the stand 30 is operated to set the height of the chin rest 16 of the stringed instrument 10 (setting of Z coordinates). After that, the tightening screw 37D of the stand 30A is operated to control and set the inclination angle of the sub-arm holder 37 relative to the central axis of the stand 30A, that is, the front-rear inclination angle of the stringed instrument. After that, the first cylindrical portion 26X is appropriately rotated to control and set the left-right inclination angle. In this way, the direction, position, height, and inclination angle about the three types of axes of the stringed instrument 10 at the time of recording are controlled and set, and they are reproduced at the time of recording. When there are multiple instruments, the relative placement of the instruments is also taken into consideration.

[0049] In the above embodiments, a stand is used to support the holder, but a conventional microphone stand or the like can be used or improved to increase its strength, or a tripod for cameras and other optical instruments can be used instead of a stand. In order to hold an expensive stringed instrument safely in space, a tripod with sufficient strength can be used. [Industrial Applicability]

[0050] The string instrument holding device of the present invention can hold various string instruments in space at the same height and inclination angle as when they were recorded, when the string instrument is driven to play automatically by a device that vibrates the string instrument in response to a sound source signal, and can provide a playback environment similar to that of a live performance.Therefore, it is useful in various industries, including various music providing businesses that include performances using string instruments, movie screening businesses that use string instruments, theater, ballet, and other performance businesses that use string instruments, as well as sound source devices for playing music using string instruments, string instrument excitation devices, the vibration transmission units that are part of these, and the design, manufacturing, sales, and installation of string instrument excitation systems that include them.
