Abstract
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.
Claims7
A speaker device comprising:
- an acoustic-vibration member;
- an actuator that is driven based on a sound signal and that includes a displacement-output unit that can obtain a displacement corresponding to the sound signal;
- and
- a displacement-output-transfer member configured to connect the displacement-output unit to a predetermined point on a face of the acoustic-vibration member,
- wherein 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.
A speaker-excitation method comprising the step of transferring a displacement corresponding to a sound signal to a predetermined point on a face of an acoustic-vibration member via a displacement-output-transfer member connected to the predetermined point by using an actuator so that the acoustic-vibration member is excited in a face direction from the predetermined point.
