Summary:A loudspeaker (21) comprises a diaphragm (22) having a vibrating portion (215) and an annular conductive portion (28), a current feeding coil (23) facing the conductive portion (28) with a predetermined magnetic gap, and a magnetic circuit (24, 25, 26, 211) comprising a top plate (24), a magnet (25) and a yoke plate (26) to which the current feeding coil (23) is attached. A capacitor which forms a high-pass filter together with the internal resistance of the current feeding coil (23) is connected serially with the current feeding coil (23).
