FIG. 2 is a schematic cross-sectional view corresponding to FIG. 2, showing a state in which the adjustment disk is at the origin position. It is a schematic perspective view of the conventional vibration sounding type musical instrument invented by the inventor.

Hereinafter, embodiments of the vibration-sounding musical instrument according to the present invention will be described with reference to an embodiment shown in the accompanying drawings.

FIG. 1 shows a schematic perspective view of a vibration sounding musical instrument according to the present invention, and FIG. 2 shows a schematic cross-sectional view taken along the line AA in FIG.
As shown in the drawing, in this instrument, an elongated thin plate-shaped metal sounding rod 1 and one end of the sounding rod 1 are fixed to the outer peripheral surface, and the sounding rod 1 is wound and unwound on the outer peripheral surface by rotation. A length adjusting disk 2 that can be adjusted, a holding rod 3 that fixedly supports a free portion 1a of the sounding plate 1 that is not wound around the adjusting disk 2, and a sounding rod 1 when the sounding rod 1 vibrates. A claw member 4 arranged below the sounding rod 1 so that the back surface of the claw member 4 is in contact with the sounding rod 1 and a vibrating plate 5 to which the claw member 4 is fixed are housed inside the housing 6. In this embodiment, the housing 6 is composed of an upper housing 6a and a lower housing 6b, and the sounding rod 1, the adjusting disk 2, the pressing rod 3 and the claw member 4 are housed in the upper housing 6a, and the diaphragm 5 is held between the upper housing 6 and the lower housing 6b.
The length adjusting disk 2 includes a shaft 2a, and the shaft 2a is rotatably supported by the upper housing 6a. Further, the shaft 2a can be fixed so as not to rotate by tightening the fixing screws 2b provided on the side surface of the upper housing 6a. Further, the adjusting disk 2 is provided with an operating lever 2c, and the operating lever 2c projects to the outside of the upper housing 6a through a notch 6c provided from the upper rear portion to the rear surface of the upper housing 6a. ing. As a result, by rotating the adjusting disk 2 via the operating lever 2c, the metal sounding rod 1 can be wound or unwound on the outer peripheral surface of the adjusting disk 2.
The presser bar 3 is made of a cylindrical body, is provided with a notch (unsigned) capable of surface contact with the sounding bar 1, and fixedly supports the sounding bar 1 from below near the sounding bar 1 away from the adjusting disk 2. .. As a result, the frequency of the sounding rod 1 is determined by the distance from the position pressed by the pressing rod 3 on the sounding rod 1 to the tip. The presser bar 3 is pivotally supported by the upper housing 6a, and one end thereof projects from the upper housing 6a so that the rotation angle position of the presser bar 3 can be adjusted from the outside. Therefore, when the presser bar 3 is rotated, the angle of the sounding bar 1 can be changed, and as a result, the distance between the sounding bar 1 and the tip of the claw member 4 can be finely adjusted to an appropriate distance.
The claw member 4 is preferably arranged in the center of the diaphragm 5. The diaphragm 5 may be any material as long as it can amplify the vibration of the sounding rod 1, and may be made of, for example, a thin plastic plate.
The tip of the sounding rod 1 extends to the outside of the housing 6 through an opening 6d provided on the front surface of the upper housing 6a.
A resonance chamber 7 is provided below the lower housing 6b, that is, the diaphragm 5, and the chattering sound generated by the collision between the sounding rod 1 and the claw member 4 passes through the vibrating body 5 and the resonance chamber 7. It is enlarged and exits to the outside through the opening 7a provided in the resonance chamber 7.
Although not shown, preferably, a cover imitating the shape of a tongue is attached to a portion of the sounding rod 1 protruding from the housing 6. By drawing eyes and nose on the front surface of the housing 6, it looks as if a person or animal sticks out the tongue and moves the tongue up and down during use.

The operation of the vibrating sounding musical instrument configured as described above will be described. FIG. 3 is a diagram corresponding to FIG. 2 of a vibrating sounding type musical instrument in a state where the lever 2a is open. According to the vibration sounding instrument configured as described above, since the linear sounding rod 1 is wound around the outer circumference of the adjustment disk 2, when the lever 2a is released, the sounding rod 1 returns to its original shape. The rotation angle position of the adjustment disk 2 returns to the origin due to the spring force that is about to return.
In this state, as shown in FIG. 2, by operating the lever 2a to rotate the adjusting disk 2, the sounding rod 1 is wound around the outer circumference of the adjusting disk 2 and shortened. Therefore, the sounding rod 1 can be made to an arbitrary length by adjusting the operation of the lever 2a, and thereby the frequency, that is, the pitch can be adjusted.
In the state of FIG. 2 or 3, when the user flips the tip of the sounding rod 1 with a finger, the sounding rod 1 vibrates and continuously collides with the claw member 4 at high speed. A chattering sound is produced by continuous high-speed contact between the sounding rod 1 and the claw member 4. Since the frequency generated by the claw member 4 is lower than the frequency of the sounding rod 1 itself, the chattering sound becomes a low tone as a result. The chattering sound due to the vibration of the claw member 4 generated by the contact between the sounding rod 1 and the claw member 4 is amplified via the diaphragm 5 and the resonance chamber 7 and goes out to the outside.
The pitch can be changed by moving the lever 2a during the vibration of the sounding rod 1.
As described above, this vibrating sounding type musical instrument is different from the kalimba that sounds by the vibration of the sounding rod 1 itself in that the sound is produced by the continuous contact between the sounding rod 1 and the claw member 4. Therefore, the distance between the sounding rod 1 and the claw member 4 when the sounding rod 1 is not vibrating is set to the distance at which the sounding rod 1 effectively contacts the claw member 4 when the sounding rod 1 vibrates. There is a need to. This adjustment can be performed by rotating the presser bar 3.

In this embodiment, the housing 6 is formed by the upper housing 6a and the lower housing 6b, and the diaphragm 5 is sandwiched and held between the upper housing 6a and the lower housing 6b. Not limited to the example, for example, the housing 6 may be integrally configured so that the diaphragm 5 can be slid in and out from the side.
Further, in the present embodiment, the pressing rod 3 is provided with a notch so that the sounding rod 1 can be pressed by the notch, so that the angle of the sounding rod 1 can be adjusted by the rotation of the pressing rod 3. However, this configuration is not limited to this embodiment, and for example, the presser bar 3 itself may be configured to be movable upward and downward, and the presser bar 3 itself may be movable. May be fixed, and the diaphragm 5 including the claw member 4 may be configured to be movable up and down.
Furthermore, in this embodiment, a perfect circular disk is used as the adjustment disk 2, and the shaft 2a is provided at the center of the disk 2. However, this configuration is not limited to this embodiment. For example, the adjusting disk 2 may be an elliptical disk, or the shaft 2a may be provided at an eccentric position so that the linearity of the sounding body 1 can be ensured as much as possible.
In the above-described embodiment, an example in which a vibrating sounding instrument is used alone is described. For example, a plurality of vibrating sounding instruments are prepared, and the length of the sounding rod 1 is adjusted so that the pitches are different from each other. By fixing the adjusting disc 2 with the fixing screw 2c, it is possible to play a melody by playing a plurality of sounding rods 1 having different pitches with a finger like a kalimba. In this case, preferably, the housing 6 can be configured to be connectable to the adjacent housing 6.
