Abstract
A gong striking mechanism is provided, which comprises a driving electric motor mounted on a frame within a gong, and conversion means rotationally connected directly or indirectly to the motor shaft for converting continuous rotational motion of the motor shaft to reciprocal gong striking motion. In a preferred embodiment of the invention the conversion means comprises an eccentric cylinder fixed to the motor shaft, and a hammer made of hollow cylinder in spaced internal arrangement with the eccentric cylinder to absorb impact strength and improve sound volume.
Claims1
A gong striking mechanism comprising:
- an electric motor mounted on a frame within a gong, said motor having a shaft, said shaft rotatably engaging an eccentric collar, and a hollow hammer having an outer surface adjacent to said gong and an inner surface disposed around said eccentric collar and spaced apart from said collar to absorb impact force and produce improved gong volume when the motion of the shaft, eccentric collar and hammer causes the outer surface of said hammer to strike the gong.
