摘要： A cylindrical frame is mounted in a cabinet and a magnetic circuit is provided at an end of the frame. A diaphragm having a peripheral free edge is connected to a coil bobbin and a cylindrical ring is secured to the free end edge and disposed in a cylindrical supporting portion of the frame. An annular sealing member is secured to the cylindrical ring so that an outside peripheral wall thereof is slidably contacted with an inside wall of the cylindrical supporting portion of the frame.
