Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a musical tone control device that controls musical tones according to the bending of a finger.

[Prior art 1] Conventional musical tone control devices are equipped with vias that can be inserted into electronic organs.
As represented by guitars, wind instruments, etc. The generation of musical sounds was controlled by hitting the keys on the keyboard, plucking the strings, and blowing air into the tubes. [Problems to be Solved by the Invention] However, with the above-mentioned peer-equipped electronic organ, the device itself is large and cannot be carried, so there are significant restrictions on the position and posture of playing the instrument. I can't hope to move my body freely. Also, for guitars, wind instruments, etc. Since it is portable, there are no restrictions on the performance position, but since it is necessary to hold the instrument in the hand, it is difficult to expect freedom of movement of the body during performance. Focusing on these points, the applicant filed a patent application in 1986-12.
No. 1486, the title of the invention is "Musical sound control device", in which the lower end of a resin elongated member that is worn along the fingers of the hand is fixed to the upper end of a flat base member that is worn on the palm of the hand. By providing a slit in the middle of the elongated member, it is possible to bend the same, and by providing a rotation detector in the middle position, the bending is detected, and the bending is detected according to the detection result. We have proposed a musical tone control device that controls musical tones according to finger bending by outputting musical tone control signals. According to this proposed device, it is possible to control the musical tones by simply wearing the device on the hand and bending the fingers, so it is expected that the body can move freely, and it is possible to enjoy the generation of musical tones along with the movement of the body. can. However, in the above proposed device,
Although it is possible to bend the fingers, it is not possible to open and close the fingers from side to side, which restricts the free movement of the fingers, resulting in unnatural finger movements and the inability to move the hands freely. was there. The present invention has been made to solve the above problems, and its purpose is to realize natural finger movements and free hand movement in the proposed device, which allows you to enjoy the generation of musical sounds as your body moves. The present invention aims to provide a musical tone control device that enables the following. (Means for solving the problem) In order to achieve the above object, the first invention (the invention according to claim 1) has a structural feature that is attached to the hand and detects the bending of the finger. A musical tone control device that outputs a musical tone control signal for controlling musical tones includes a plate-shaped base member that is attached to the back of one hand, and a lower portion that rotates around an axis substantially parallel to the base member at the upper end of the base member. a first rotating member that is rotatably connected to the first rotating member; The present invention includes a second rotary member having a lattice shape, and a detection means for detecting rotation of the first rotary member about an axis substantially parallel to the base member and outputting a musical tone control signal in accordance with the detection result. Further, a structural feature of a second invention (invention according to claim 2) is that, in the first invention, the detection means is assembled at a connecting position between the base member and the tj11 rotating member. [Operations and Effects of the Invention 1] In the first invention implanted as described above, the first rotating member is rotatable with respect to the base member around an axis substantially parallel to the base member, In addition, since the m22 rotary member is rotatable relative to the first rotary member around an axis substantially perpendicular to the base member, when the musical tone control device is worn on the hand, the second rotary member is able to move forward and backward of the finger. It rotates in the front-rear direction and the left-right direction in response to the bending operation and the opening/closing operation to the left and right.In addition, in such a case, the detection means detects the rotation about the axis substantially parallel to the base member of the first rotating member and detects the rotation. Since a musical sound control signal is output according to the detection result, the musical sound is controlled according to the bending motion of the finger in the front-back direction.As described above, according to the first invention, the musical sound is controlled according to the bending motion of the finger in the front-back direction. The proposed device allows you to enjoy the generation of musical sounds while freely moving your body, as the musical sounds are controlled according to the bending motion, and the fingers can be bent in the front-rear direction and opened/closed in the left-right direction. In addition to the same effect as above, the fingers can move freely, realizing natural finger movements and allowing free movement of the hand.Furthermore, according to the second invention, the fingers can be moved in the front-back direction. The detection means for detecting the bending of the finger is assembled at a connecting position between the base member and the first rotating member, and the connecting position is attached to the 11th rotating member and the second rotating member that enable the finger to open and close in the left and right direction. Since it is located below the connection position with the detection means, that is, on the side of the base member, the wire material such as the lead wire that outputs the detection result from the detection means to the outside can be used to bend the finger in the front-rear direction and open and close it in the left-right direction. The wire is not bent in response to movement, and the durability of the wire is improved. [Example] An example of the present invention will be described below with reference to the drawings. Figure i2 each shows a musical tone control device according to the present invention. This musical tone control device has gloves 10 with a double structure on the lower side of the hand.
It is housed inside the double structure and has a base 20 that is worn along the palm of the hand. baseffl! As shown in FIGS. 1 to 3 UgJ, the gloves 20 are integrally molded with a thin synthetic resin or the like and are curved to fit the shape of the palm of the hand, so that the gloves 10 fit well into the palm of the hand when worn on the hand. It has become. Five connections @30f 30... corresponding to each phase are provided on the upper end side of the base 20, and the connection parts 30, 30... correspond to each phase and also have connections for bending in the same phase. The lower ends of five elongated rotating parts 40, 40, etc., which rotate back and forth accordingly, are connected to each other. Each connecting portion 30 enables the rotation of the rotating portion 40, and connects the fixed member 31 connected to the base 20 side and each rotating portion 40.
It consists of a rotating member 32 connected to the side. Fixed member 31
is fixed to the base 20 by a stop pin 21 at the lower side, and has a pair of annular parts 31a and 31b integrally formed at the middle of the upper end, as shown in FIGS. 1 and 4. A shaft 33 rotatably passes through the annular portions 31a and 31b. The rotating member 32 also has a pair of sparse portions 32a integrally formed on both sides of the lower end. 3.2b, and the annular portions 32a, 32b pass through the shaft 33 and are fixed to the same shaft 33. In such a case, with the glove 10 on the hand, the annular portion 31
a, 3 l b, 32 a, 32 b and the shaft 33 are located opposite the joint of the finger furthest from the fingertip (second joint for the thumb, third joint for fingers other than the LT finger) The rotating member 32 of the connecting portion 30 and the rotating portion 40 rotate according to the bending of the finger around the joint.
The entire body rotates in the front-rear direction with respect to the base 20. Further, a cylindrical case 34 is fixed to the shaft 33, and a disc-shaped slider 35 made of a conductive leaf spring is fixed to the side surface of the annular part 31b of the fixing member 31. It is fixed so as to face the printed board 36 of. On the printed circuit board 36, as shown in FIG. 5, a conductor #36a is formed in a circular shape with both ends slightly separated from each other. A resistor M36b is provided slightly apart from the conductor 19136a and the resistor W36.
Both legs 35a and 35b of the slider 35 are in contact with b. The slider 35, the conductor layer 36a, and the resistor/9136b constitute a rotation detector RD. The ends of lead wires 37a, 37b, and 37c soldered to the back surface of the printed circuit board 36 are electrically connected to one end of the four electric conductor layers 36a and to both ends of the resistor W36b, respectively. The same lead wire 37
a, 37 b, and 37 c are pulled out onto the base 20 from the holes formed in the annular portion 3xb of the fixing member 31, and are fixed at appropriate locations on the base 20 by the fasteners 22, 22, etc. so as to be pushed downward. It has been extended to Each rotating portion 40 is constituted by a metal rod member 41 having an axial length that differs depending on the length of each phase, and a cylindrical member 42 integrally molded from synthetic resin. The lower end of the rod-shaped member 41 is rounded into a circular shape, and the one-rotation member 32
It is rotatably wound around the outer periphery of a pin 38 that is integrally formed or fixed to. The pin 38 has a disk-shaped head 38a that is integrally formed or fixed, and the lower end of the rod-shaped member 41 is prevented from being pulled out by the head 38a. The pins 38 are arranged at opposing positions slightly below the base of the fingers when the musical tone 111m device is worn, and the rotating portion 40 responds to the opening and closing movements of the fingers in the left and right directions.
Rotation in the left-right direction with respect to the base 20 and the connecting portion 3o is permitted. The upper end of the rod-shaped member 41 enters into the cylindrical member 42 from its lower surface so as to be able to move forward and backward, and a stopper member 43 fixed to the tip of the rod-shaped member 41 prevents the cylindrical member 42 from coming off from the lower surface. 4 A finger rest part 44 is formed integrally with the cylindrical member 42 at the upper part of the cylindrical member 42 or is attached to the same member 42, and the finger rest part 44 is curved in the shape of a fingertip. The glove 10 is made thin so that the finger rest 44 fits the fingertip when the glove 10 is worn on the hand. Next, a musical tone generating device whose generation is controlled by the musical tone controlling device having such a configuration will be explained. As shown in FIG. 7, this musical tone generating device is connected to lead wires 37a to 37c led from a rotation detector RD and carried on a part of the body, and is connected to a musical tone control signal forming circuit 51. A musical tone signal forming circuit 52 and a sound system 53 are housed therein. The other ends of the lead wires 37b and 37C connected to both ends of the resistor #36b constituting the rotation detector RD are connected to the It source +V and grounded, and are connected to the conductor N36a. A voltage corresponding to the position of the slider 35, that is, the rotational position of the rotating part 40 in the front-rear direction is taken out from the other end of the lead wire 37a. The other end of the lead wire 37a is connected to the musical tone control signal forming circuit 51.
The A/D converter 51a converts the input analog voltage into a digital signal, and converts the digital signal into a touch response signal TR to the musical tone signal forming circuit 52. and one input of the comparator 51b. The other input of the comparator 51b receives a reference level signal L representing a predetermined reference level.
V. When the touch response signal TR exceeds the reference level signal Lvr,t, the comparator 51b supplies a key-on signal KON to the tone signal forming circuit 52. The musical tone signal forming circuit 52 forms musical tone signals with pitches assigned to each phase in response to the input of the key-on signal KOH, and also changes musical tone elements such as the volume and timbre of the formed musical tone signal in response to the touch response signal TR. The controlled musical tone signal of the musical tone element is supplied to the sound system 53. The sound system 53 includes an amplifier, a speaker, etc., and produces musical tones corresponding to the supplied musical tone signals. Next, the operation of the embodiment configured as described above will be explained. First, the performer (the person who controls the generation of musical tones) starts from the musical tone control signal forming circuit 51. A musical tone generating device containing a musical tone signal forming circuit 52 and a sound system 53 is worn on a part of the body, for example, the waist, and a glove 10 containing the musical tone controlling device is worn on the hand. In such a case, gloves 10 of various sizes are prepared in advance depending on the size of the player's hands, and the player selects gloves 10 as appropriate. With this selection, when the glove 10 is worn on the hand, the musical tone control device consisting of the base 20, the connecting part 30, and the rotating part 40 will correspond to the size of the hand, and at the same time, the base 20 will be adapted to the shape of the palm. Since the finger rest part 44 is also molded to match the shape of the fingertip, the base part 20 fits well in the palm of the hand, and the finger rest part 44 fits well in the fingertip, making it difficult for the musical tone control device to move. In addition, in this state, as shown in FIG. 8, the shaft 33 of each connecting portion 30 comes to be at the lower position P1 of the third joint of each phase except the thumb, and the pin 38 of the connecting portion 30 The base of the finger comes to be at a position P2 slightly below the root, making it easier to bend the finger at the third joint and open and close the finger in the left-right direction. Regarding the thumb,
The third joint corresponds to the second joint. Furthermore, even if you bend your fingers back and forth and open and close them in the left and right directions as described above, the center of the bending back and forth is #h.
33 is located below the bin 38 which is the center of opening and closing in the left and right direction, and the lead wires 37a to 37c connected to the rotation detector RD which detects the front and back bending are connected to the annular part of the fixing member 31 at their tips. Since the leads M 37 a to 37 c are fixed to the printed circuit board 36 fixed to the rotary part 31 b and are drawn out through the open annular part 31 b, there is no possibility that the leads M 37 a to 37 c will be disconnected due to the rotation of the rotary part 40 . In this state, when a desired finger other than the thumb is bent at the third joint (in the case of the thumb, it is bent at the second joint), the rotating part 40 rotates around the axis 33 of the connecting part 30, as shown in Figure fJ9. rotate forward relative to the palm of the hand. When bending the fingers, the first and second joints also bend slightly as the third joint bends.
The entire finger is slightly rounded inward (the joints are also slightly curved), and the length from the base to the tip of the finger changes depending on the rounding, but in this case, the cylindrical member 42 is displaced downward. As a result, the tip of the rod-like member 41 penetrates deeply into the cylindrical member 42 as shown in the figure and changes the total axial length of the rotating portion 40, so that bending of the finger is not hindered. As described above, when the finger is bent, the rotating member 32 of the connecting portion 30 rotates forward with respect to the palm, and as the rotation occurs, the shaft 33 fixed to the annular portions 32 a and 32 b rotates around the fixed member 31 . It rotates on the inner periphery of the annular parts 31a and 31b. As the shaft 33 rotates, the slider 35 fixed to the case 34 rotates on the conductor N 36 a and the resistor # 36 b of the printed circuit board 36, and an analog signal corresponding to the bending of the finger is output from the lead wire 37 a. Voltage is extracted. This analog voltage is supplied to the musical tone control signal forming circuit 51, where an A/D converter 51a in the same forming circuit 51 forms a touch response signal TR. A key-on signal KON is generated. These touch response signal TR and key-on signal KO
N is supplied to the musical tone signal forming circuit 52;
is the corresponding Ryokango TR. Based on the KON, a musical tone signal having a pitch corresponding to one finger bent and with musical tone elements such as timbre and volume controlled according to the amount of bending is generated, and the musical tone signal is supplied to a sound system 53. Since the sound system 53 generates a musical tone corresponding to the supplied musical tone signal, the system 53 generates a musical tone corresponding to the bending of the finger. In this way, according to the musical tone control device described above, the glove 10 is simply put on the hand, and the generation of musical tones is controlled according to the bending of each phase, so that the performer is free from restrictions on performance position and body movement. Musical instruments can be enjoyed while being accompanied by free body movements, and those who listen to the music can also enjoy the music by adding visual elements to the movements. In addition, in controlling musical sounds according to the bending of the fingers, the joint of the finger furthest from the fingertip (fi
The second joint for the R finger, and the third joint for fingers other than the thumb.
Since the musical tone is controlled according to the bending of each phase with the joints as the axis, it becomes easier to bend each phase independently, and the musical tone can be accurately controlled according to the performer's will. Furthermore, according to the above embodiment, the bending motion of the finger in the front-back direction is performed by the connecting portion 3.
0 annular portion 31a, 3lb, 32a,
32b and the shaft 33, and the opening and closing movements of the fingers in the left and right directions are made possible by the bottle 38 of the connecting part 30 and the lower end of the rod-shaped member 41, so each phase of movement is free, and as a result, Your hands can move freely. In addition, in the above embodiment, the musical tone control device and the glove 1
Although only one hand is shown as 0, musical tone i corresponds to 1 and both hands.
#A control device and gloves 10 may be provided to control the musical tone according to each phase of movement of both hands. Furthermore, in the above embodiment, the musical tones are controlled in accordance with the bending of all the fingers, but the musical tones may be controlled in accordance with the movement of only one or more fingers. Further, in the above embodiment, the musical tone control signal forming circuit 5
1. Musical sound signal forming surface IJ&52 and sound system 5
3 is attached to a part of the body, but a rotation detector R is installed in the glove 10 of the above embodiment.
A wireless transmitter for transmitting the detection result by D is built-in, and the transmission signal from the wireless transmitter is received in a musical tone generating device that is worn only on the glove 10 and configured similarly to the above embodiment. In addition to having a built-in receiver, the musical tone generating device may also be placed near the performer, which allows the performer to move his or her body even more freely. Further, in the above embodiment, the detection results by the rotation detector RD, that is, the generation of musical tones with pitches assigned to each phase according to the finger movements, and the timbre of the same musical tones. Although musical tone elements such as tone ii are controlled, the octave of the generated musical tone, the application of effects, the degree of the effects, etc. may also be controlled in accordance with finger movements. Further, in the above embodiment, the rotation of the rotating part 40 in response to the bending of the finger is detected as a continuous amount by the rotation detector RD provided in the connecting part 30, but the rotation detector RD
It may be configured with a switch that is turned off (or turned on) until the rotation part 40 rotates by a predetermined angle or more, and turned on (or turned off) when the rotation angle of the rotation part 40 reaches a predetermined angle or more. In this case, it is preferable to control whether or not a musical tone is generated, whether or not an effect is applied, etc. in accordance with the rotation of the rotating section 40. Furthermore, in the above embodiment, only the forward and backward rotation of the finger is detected and the musical tone is controlled according to the detection result, but the horizontal rotation of the finger is also detected and the musical tone is controlled according to the detection result. Control of the musical tone may be added. In such a case, the rotation of the rod-shaped member 41 around the pin 38 may be detected by a rotation detector, and the musical tone may be controlled in accordance with the detection result.
