Abstract
A flat panel speaker according to an embodiment of the disclosure includes a flat panel and a plurality of vibrators that are disposed on a back surface of the flat panel. The plurality of vibrators are disposed to avoid a location that most easily vibrates in an entire range of audio frequencies when vibration is generated in the flat panel by the plurality of vibrators. A large stationary wave with respect to the flat panel therefore does not easily occur.
