A piezoelectric speaker converts an electric signal into a sound that a person can hear through the ears. The piezoelectric speaker comprises: a casing; a separation unit which is located in the casing and separates an internal space of the casing; a support base which is located in the casing wherein one end of the support base is fixed to the separation unit; a high-pitched tone speaker which is formed by a piezoelectric module and supported by the other end of the support base; and a dynamic low-pitched tone speaker which is installed in the casing and located on the other side facing the high-pitched tone speaker of the separation unit. |
