Disclosed is a dynamic speaker having a piezo speaker with an eccentrically disposed ceramic element. The dynamic speaker includes: a frame having an installation unit formed therein; a vibration plate installed in the installation unit; a gasket; a piezo speaker comprising a metal plate with low note discharge holes and a ceramic piezoelectric element coupled to an outside surface of the metal plate and installed in the gasket spaced from the oscillation plate at a certain interval; and a PCB for applying an electric signal for the generation of sound to a voice coil and the piezo speaker. According to one embodiment of the present invention, the low note discharge holes are formed to approach and face a nozzle hole, thereby enabling the discharge of a low note to be realized more easily. |
