The invention discloses a vibrating plate device of an electromagnetic vibrator; the vibrating plate device comprises at least one vibrating plate module with a substrate, a vibrating plate and an upper dangling edge; and the inner edge and the outer edge of the upper dangling edge are connected to the vibrating plate and the substrate respectively to form a whole; two vibrating plate modules are further fixedly connected in the opposite direction to form the vibrating plate device. According to the special structure of the vibrating plate device, when a voice coil drives the vibrating plate, due to the interaction of two dangling edges and two vibrating plates, the rolling caused by the voice coil driving the vibrating plate is offset, so that the voice coil drives the vibrating plate to realize a vertical stroke, thereby replacing a conventional elastic wave. |
