According to the present invention, a dynamic speaker with a piezo speaker comprises: a frame including an expanded installation part; a vibration plate including a permanent magnet and a voice coil arranged on an inner side of an accommodation part and installed in the installation part; a gasket fixing the vibration plate to the installation part; and a PCB coupled to an outer side of the frame and applying electricity to the voice coil. The dynamic speaker adds a suspension structure to a metal plate to increase a vibration amplitude in case of vibration of a piezoelectric element, thereby providing a unit for increasing a high volume. |
