The present invention provides a piezoelectric speaker, which is formed in a relatively simple structure in such a manner that the speaker is miniaturized and thinly made to be applied to flat displays that are getting the spotlight in recent years and to various application products such as embedded speakers for a vehicle or the like. Particularly, said piezoelectric speaker shows the similar acoustic features to the existing magnetic circuit or voice coil-type speaker by effectively improving low-sound area properties. |
