摘要
PURPOSE: A bone conductive speaker is provided to reduce the size and weight of a bone conductive speaker by locating a permanent inside a voice coil.;CONSTITUTION: A voice coil(40) is installed inside a yoke(20) which comprises the structure of a bone conductive speaker. The inner part of the voice coil is formed into an empty space instead of installing a central magnetic pole. A permanent magnet(90) is attached inside the iron plate(60) of a vibration plate(70). The permanent magnet is vibrated according to a voice signal inside the voice coil. A gap between the central magnetic pole and the iron plate of the vibration plate is accurately controlled. The calibration width of a vibration property is increased according to the magnitude change of the voice coil and the permanent magnet.;COPYRIGHT KIPO 2011
