PURPOSE: A vibration speaker is provided to change only shape of a PCB and easily supply a power when the shape of a terminal is changed according to the request of a user. CONSTITUTION: A vibration plate(50) is installed at an upper surface of a case(10), and a grille is located at a lower surface of the case(10). Guide rails(100) are parallel and extendedly formed at one side of a front surface of the case(10) to be isolated each other at a certain interval, and a safety-receiving groove(110) is formed in an internal portion of the guide rail(100) and an asperity(120) is formed at an internal wall surface of the safety-receiving groove(110). A PCB(200) is inserted into the safety-receiving groove(110) of the guide rail(100) for supplying an external power to the case(10), and a concave groove is formed at an external surface of both sides to be bridged to the asperity(120).
