COMPACT SPEAKER, ESPECIALLY HAVING RIB TO DESIGNATE POSITION OF PCB BOARD

摘要

PURPOSE: A compact speaker is provided to perform various wire connections without regard to the position of a speaker connection port by arranging the port on a PCB board efficiently. CONSTITUTION: The compact speaker includes a frame(111) having an inner space, and a magnet(114) placed upward, and a top plate(115) forming a magnetic circuit by being formed on an upper plane of the magnet. A bottom plate(112) forms the magnetic circuit together with the magnet. A diaphragm(116) is assembled on the upper plane of the frame. A voice coil(117) vibrates the diaphragm as moving up and down straightly according to magnetic field. A PCB board(120) is bonded to the outside of the frame, and includes the first and the second and the fifth and the sixth port connecting a wire selectively in order to apply a driving supply power to the speaker. The PCB board also includes the third and the fourth port to connect a lead wire of the voice coil.
