摘要：
A speaker has an acoustic diaphragm, and an actuator that is driven based on a first acoustic signal. The actuator has a transmission portion that is directly or indirectly attached to the acoustic diaphragm and transmits a displacement output of the actuator to the acoustic diaphragm. The speaker also has a sounding body that is driven based on a second acoustic signal that is identical to or different from the first acoustic signal.
