  Now, the use forms of the above-described resonance generators have been increasingly diversified in recent years, and in terms of performance, in order to ensure excellent resonance generation capability and appropriately stop generated resonances. Is also required. For example, when a melody is played by a plurality of devices, the reverberation of the resonance sound may get in the way.

  The resonance can be stopped by contacting the silencer with the resonance generator. Here, the muffler means a member that absorbs the vibration of the resonance generator. However, if a separate drive means for bringing the silencer into contact with the resonant sound generator is provided, there is a problem that the apparatus becomes complicated and large, and the control becomes complicated. In short, there is a need for a device for more easily achieving a configuration in which the generated resonance is stopped at a required timing. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a resonance sound generator configured more rationally.

The invention described in claim 1 of the present application comprises a resonance generator, a hammer for striking the resonance generator, and drive means for driving the hammer, and the hammer strikes the resonance generator. In the resonance sound generating device for generating resonance sound, a silencer that abuts on the resonance sound generator and stops the resonance, and a silencer contact means that abuts the silencer on the resonance sound generator The hammer swings about a shaft supported by a support and is urged toward a predetermined stop position, and is moved from the stop position by the driving means to move the resonance sound. The sound generator is struck, and the silencer is separated from the resonance sound generator by an impact caused by the impact, and the silencer contact means is interlocked with the hammer, Ar provided Comprising a part and a roller part which is supported on the tip of the arm portion, when the hammer is moved to the stop position, the resonance the roller portion the angle of the arm portion is changed is while pressing the silencer body It is a resonance generator which is configured to move toward the sound generator and abut the silencer against the resonance generator.

  According to the present invention, it is possible to obtain a resonance sound generator that is configured more rationally.

  Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 includes a resonance generator 100, a hammer 200 that strikes the resonance generator 100, and a drive unit 300 that drives the hammer 200. Strikes the resonant sound generator 100 to generate a resonant sound. The resonance generator 1 also includes a silencer 400 that abuts the resonance generator 100 and stops the resonance, and a silencer abutment means 500 that abuts the silencer 400 on the resonance generator 100. ing. Each component is supported by a wall body 600 and a support body 610 installed on the wall body 600.

  The resonant sound generator 100 is a metal or ceramic rod. It is partially fixed to the support 610 and is provided so that its major axis is in the vertical direction. Alternatively, it may be hung on the ceiling or the like.

  The hammer 200 is moved from a predetermined stop position by the driving means 300 and strikes the resonance generating body 100. The hammer swings around a shaft portion 201 supported by a support body 610, a metal striking portion 210 that abuts against the resonance generator 100 and strikes it, and a rod-like shape that supports the striking portion 210. The base part 230, the base end part 230 which was pivotally supported by the axial part 201 and fixed the rod-shaped part 220, and the collar part 240 provided in the base end part are provided. Note that the rod-shaped portion 220 is a flexible member. The driving means 300 is connected to the collar portion 240.

  Further, the hammer 200 is urged toward the stop position. Specifically, a coil spring 250 is provided between the flange portion 240 and the support body 610 to connect them, and the hammer 200 generates resonance sound due to its own weight and the force of the coil spring 250. It is urged | biased in the direction away from the body 100, and it has the structure which stops at a predetermined stop position (refer FIG.1 and FIG.2).

  The driving means 300 is formed by connecting the iron core 311 of the solenoid 310 to the flange portion 240 of the hammer 200 via the link 320. When the solenoid 310 is excited, the iron core 311 is pushed out and the hammer 200 is lifted vigorously. Then, the main point of the base end portion 230 of the hammer 200 collides with the convex portion 611 provided on the support body 610, the striking portion 210 strikes the resonance generating body 100 while the rod-shaped portion 220 is bent, and then the resonance sound is generated. Occurs (see FIG. 3).

  The muffler 400 is a cushion-like member that absorbs the vibration of the resonance generator 100. The moving direction of the silencer 400 is regulated by a guide portion 612 provided on the support 610. The illustrated guide portion 612 is a rail that penetrates the plate body 410 provided on the back surface of the muffler 400 and extends straight in the horizontal direction. The muffler 400 abuts on the resonance sound generator 100 from the direction opposite to the hammering direction of the hammer 200, and is separated from the resonance sound generator 100 by an impact caused by the impact. A white arrow in FIG. 3 indicates a direction in which the silencer 400 is separated from the resonance generator 100 due to an impact.

  After striking the resonance generator 100, the rod-shaped portion 220 is restored, the striking portion 210 is separated from the resonance generator 100, and the muffler 400 is separated from the resonance generator 100. If the solenoid 310 remains energized, the hammer 200 remains lifted (see FIG. 4). The resonance sound is continuously generated at this time.

  The silencer abutment means 500 is interlocked with the hammer 200, and the hammer 200 is brought to the stop position, and the silencer 400 is moved toward the resonance generator 100 to generate the resonance sound. It contacts the body 100. That is, as described above, when the excitation of the solenoid 310 is completed after the hammer 200 is lifted, the silencer 400 is moved in conjunction with the urged hammer 200, and the silencer 400 strikes the resonance generator 100. It is configured to stop when it comes into contact. The stop position of the hammer 200 is regulated by the silencer contact means 500.

  The silencer contact means 500 of this example includes an arm portion 510 fixed to the base end portion 230 of the hammer 200 and a roller portion 520 supported at the tip of the arm portion 510. When the excitation of the solenoid 310 is finished and the hammer 200 moves to the stop position, the angle of the arm unit 510 changes, and the roller unit 520 presses the plate body 410 provided on the back surface of the muffler 400 while resonating the sound generator. Move toward 100. When the muffler 400 abuts on the resonance generator 100, the resonance is stopped. The resonance sound generator 100 is subjected to the urging force of the hammer 200 via the silencer 400. When the hammer 200 strikes the resonance generating body 100, the roller portion 520 is detached from the plate body 410 of the silencer 400.

  According to such a configuration, a resonance sound is generated while the solenoid 310 is excited, and the resonance sound stops when the excitation of the solenoid 310 is finished. That is, it is possible to generate and stop the resonance sound only by controlling the solenoid 310.

  As described above, according to the resonance generator of this example, the generated resonance can be stopped at a required timing. The configuration for stopping the resonance sound is also simple, and the complexity and size of the apparatus can be avoided. Control is also easy. In addition, it is needless to say that the configuration of each part in the present example can be appropriately changed in design within the technical scope described in the claims, and is not limited to that illustrated in the drawings.

  The resonance generator of the present invention can be suitably used as a device for generating resonance. In particular, it is also possible to provide a melody by providing a plurality of resonance tone generators having different timbres. Moreover, it can be used suitably also as what improves the performance of a clockwork clock or a music box device.
