摘要:
A speaker device includes an acoustic-vibration member, an actuator that is driven on the basis of a sound signal and that includes a displacement-output unit that can obtain the displacement corresponding to the sound signal, and a displacement-output-transfer member configured to connect the displacement-output unit to a point predetermined on a face of the acoustic-vibration member. A displacement output of the actuator is transferred to the predetermined point via the displacement-output-transfer member, and the acoustic-vibration member is excited in a face direction from the predetermined point according to the displacement output.
