ABSTRACT:
A gong holder is secured to a resonance box. A first end of each of gong sticks is secured to the gong holder. Solenoid type hammer devices drive rod hammers that are movably disposed in a direction perpendicular to the gong sticks so that the rod hammers strike the gong sticks. Thus, real chime sound is accomplished. In addition, since the hammer devices do not associate with mechanical parts such as cams, the size of the hammer devices can be decreased and the degree of freedom of the installation thereof can be increased.
