Patent ID: 8792657

Claim:
A speaker device comprising: an acoustic diaphragm; a vibration transfer member disposed in contact with the acoustic diaphragm over a predetermined length of the acoustic diaphragm, a shape of the vibration transfer member being elongated in a longitudinal direction such that a central axis, which extends in the elongated longitudinal direction of the vibration transfer member, extends along a direction of a surface of the acoustic diaphragm, the vibration transfer member being longer in the longitudinal direction than in a width direction thereof, and the vibration transfer member being configured to transfer vibration to the acoustic diaphragm; and an actuator disposed at an end of the central axis of the vibration transfer member in the longitudinal direction, the actuator being configured to add vibration corresponding to an audio signal to be reproduced to the vibration transfer member to thereby transfer vibration to the acoustic diaphragm through the vibration transfer member and to generate sound.
