Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sound generator, particularly to a sound generator which has a large amplitude and volume of a vibrating reed, is used in a general sash area, and is often used instead of castanets.

[0002]

[Prior art]

 As shown in FIG. 1, basically, a conventional sound generator includes a shell 1 and a resonator element 2. The resonator element 2 is divided into two parts, a convex plate 21 and a conical surface 22. The circumference of the conical surface 22 is joined to a convex ring above the shell 1. A resonance chamber 11 is provided inside the shell 1 and a sound outlet 12 is provided at a lower end. When the upper side of the above-mentioned convex plate portion 21 is subjected to the external force of the finger as the main subject of pressing, the vibrating reed 2 is depressed and deformed to generate sound. When the external force is reduced or completely eliminated, the sound is generated by vibration while automatically recovering to the normal state. When the frequency of the sound is the same as the natural frequency of the resonance room 11, a larger sound comes out.

[0003]

[Problems to be solved by the invention]

 However, in the conventional generator, since the finger as the main pressing member directly presses the protruding surface of the vibrating reed 2, the amplitude of the vibrating reed 2 is always reduced by suppressing the finger as the main pressing member, that is, the sound volume is reduced. In addition, the conventional generator has a low vibration speed, a small amplitude and a relatively small sound while deformed. Therefore, the volume is increased in the resonance chamber 11 of the shell 1, but the effect is limited.

In order to solve the above-described problem, it is necessary to intervene an intermediate substance between a finger as a pressing subject and the resonator element 2 first. The intermediate material must be not rigid but elastic. Therefore, the amplitude that comes out while deforming or vibrating can be fully utilized, and is not reduced by suppressing the finger as a pressing subject.

The main point of increasing the sound volume is how to increase the speed of vibration rapidly when the resonator element 2 is dented and deformed. Another point is to release the finger as the main pusher in addition to improving the resilience of the resonator element 2. Accordingly, an object of the present invention is to provide a sound generator in which the amplitude of the vibrating reed is not reduced by suppressing the finger as the main subject of pressing, and the speed of vibration is large and the volume is large.

[0006]

[Means for Solving the Problems]

 The present invention for solving the above-mentioned problems employs the means described in claim 1. According to this means, the main structure includes the resonator element and the shell. The vibrating reed can generate sound while the shell is concave and deforming, or while recovering while automatically projecting to normal. On the other hand, an indirect elastic pressing piece is attached to the surface where the vibrating piece protrudes. The indirect elastic push piece is made of an elastic material that can recover immediately after being compressed by the force. Due to the intervention of the indirect elastic pressing piece, there is indirect contact between the finger as the main pressing element and the vibrating piece, so that the vibration of the vibrating piece is prevented from being suppressed by the direct contact, and the external force is controlled by the indirect elastic pressing piece. The potential energy can be released instantaneously while absorbing this energy. Therefore, the vibrating reed vibrates rapidly to increase its amplitude when it is concavely deformed, or when it is automatically protruding and recovers to the normal state, because it applies a reverse acting force to the finger as the main subject of pushing. And increase the volume. The sound coming out has the obvious effect of having the same level of volume as the castanets shown in FIG. 2, is used in the general toy manufacturing sector, and is often applied instead of castanets.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. (First Embodiment) First, FIGS. 3 to 6 show a first embodiment of the present invention. The sound generator according to the present embodiment basically includes a shell 1, a vibrating piece 2 and an indirect elastic pressing piece 3. A resonance chamber 11 is provided inside the shell 1 and a sound outlet 12 is provided at a lower end. Sound is transmitted from the sound outlet 12 to the outside. The resonance chamber 11 increases the volume by resonance. The resonator element 2 is divided into two parts, a convex plate part 21 and a conical surface part 22. The circumference of the conical surface portion 22 is joined to the convex ring 13 above the shell 1. When the above-mentioned convex plate portion 21 receives an external force, the vibrating piece 2 is dented and deformed as shown in FIG. When the external force is reduced or completely eliminated, as shown in FIG. 3 and FIG. 4, the vibration is automatically restored to the normal state. Generates sound both when deforming and when recovering.

In this embodiment, the indirect elastic pressing piece 3 is mainly attached to the protruding surface of the vibrating piece 2. In addition, the indirect elastic pressing piece 3 is made of an elastic material that can recover immediately after being compressed by receiving a force. For example, manufactured from high density foam sponge or high elastic rubber. As a secondary effect of the indirect elastic pressing piece 3, the finger acting as the main pressing member and the vibrating piece are brought into indirect contact with each other by the intervention of the indirect elastic pressing piece 3. That is, in order to prevent the finger or the hard pressing subject from suppressing and reducing the amplitude, the amplitude of the resonator element can be maintained at the original level by using the elastic material described above. After all, if the indirect elastic pressing piece 3 is provided between the finger as the main pressing element and the vibrating piece, the volume of the conventional generator can be increased.

The main function of the above-described indirect elastic pressing piece 3 is to rapidly increase the vibration speed while the vibrating piece 2 is deformed or recovered, and to obtain a relatively larger amplitude and volume. . As shown in FIG. 5, the indirect elastic pressing piece 3 is first compressed to absorb the energy of the external force. At that time, the potential energy is reduced, so that the potential energy is stored. Next, as shown in FIG. 5 and FIG. 6, when the external force applied to the indirect elastic pressing piece 3 constantly increases and exceeds the critical load point of the indirect elastic pressing piece 3, the indirect elastic pressing piece 3 instantaneously accelerates rapidly. Releases energy to Further, the vibration speed of the vibrating reed 2 is increased by the continuously received external force, and a larger amplitude and a volume several times higher than the conventional one are generated.

As shown in FIG. 4 and FIG. 6, when a finger as a pushing main body moves downward and pushes above the indirect elastic pressing piece 3 which is concave and deformed, energy is released by the action of inertia. The indirect elastic pressing piece 3 is compressed again. At this time, the indirect elastic pressing piece 3 applies a reverse acting force to the finger as the main subject of pressing, so that the recovery force of the vibrating piece 2 is increased. In addition, the recovery vibration speed of the resonator element 2 is relatively increased, that is, the amplitude and the sound volume are improved. Of course, the amount of the recovery cycle corresponds to the amount of the concave cycle.

(Second Embodiment) FIGS. 7 and 8 show a second embodiment of the present invention. In the second embodiment, a frog toy 4 is attached above the shell 1 of the sound generator, and a gripping tube 6 for grasping by hand is inserted below the shell 1. Then, when the handle 5 is pressed with a finger, a sound comes out. In this embodiment, a sound outlet 14 is provided below the shell 1 in order to transmit sound well.

As another example, as shown in FIGS. 9 and 10, an elliptical toy can generate sound. Also, a generator as shown in FIG. 11 can be used instead of the castanets of FIG.
