CONE TYPE SPEAKER HAVING VIBRATION REDUCING METHOD

摘要

The present invention relates to a cone-type speaker including a vibration reducing means. A speaker unit includes a center pole, a voice coil, a magnet, a plate, a cone vibration plate, a voice coil bobbin, a frame, a damper, an edge, and a dust cap. The speaker unit is built and installed in a cabinet. A fixing bolt hole is formed in the center of the speaker unit in which the center pole is located to couple the speaker unit to the center of a support piece by using a bolt coupling method, thereby enabling the support piece to reduce the vibration of the speaker unit primarily. Coupling holes, which are formed on curved parts of both ends of the support piece, are used to fix the speaker unit to the cabinet by using the bolt coupling method while preventing the frame of the cone vibration unit from being supported by the cabinet. Accordingly, only the vibration waves not amplified through the voice coil are canceled through the support piece and the cabinet and minutely affect the amplified sound, thereby enabling an audience to listen to clear and correct pronunciation without including any vibration waves in the auditorium.
