PURPOSE: A speaker for decreasing the leakage magnetic flux is provided to increase the output sound pressure level and the efficiency of the speaker by increasing the efficiency of the magnetic circuit of the speaker. CONSTITUTION: A speaker for decreasing the leakage magnetic flux includes a magnet(20), a pole piece(30), a frame(40), a voice coil(50), a vibrational plate(60), a damper(70), a space(110), a connection protrusion(120), a supporting plate(130) and a yoke(100). The space(110) is formed on the bottom of the speaker. The connection protrusion(120) is formed on the top of the peripheral surface. The supporting plate(130) is formed on the bottom inside of the space(110). And, the yoke(100) is provided with a fixing groove having a size corresponding to the magnet, wherein the fixing groove is formed on the supporting plate(130).
