Abstract:

Disclosed are a bone conduction speaker and compound vibration device thereof, the compound vibration device comprising a vibration conducting sheet and a vibration plate; the vibration conducting sheet is configured to be a first circular ring body, and at least two first support rods are converged to the center of the first circular ring body; the vibration plate is configured to be a second circular ring body, and at least two support rods are converged to the center of the second circular ring body; the vibration conducting sheet and the vibration plate are secured together; the first circular ring body is fixed on a magnetic system; and the second circular ring body is fixedly provided with a voice coil affected by the action of the magnetic system. The bone conduction speaker and compound vibration device of the present invention employ a fixedly connected vibration conducting sheet and a vibration plate, thus having a simple process and low cost; and the two components of the compound vibration device can adjust to both low frequency and high frequency, thus the obtained frequency response is flatter and the sound is wider.
