A speaker has an acoustic diaphragm, and an actuator that is driven based on an 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 actuator vibrates with the acoustic diaphragm by at least its component of the vibration along a plane of the acoustic diagram.
