SLIM TYPE SPEAKER CAPABLE OF ACQUIRING DESIRED ACOUSTIC CHARACTERISTIC BY PREVENTING TWIST GENERATION ALONG THE MAJOR AXIS DIRECTION OF A VIBRATION PLATE PART DURING VIBRATIONS

摘要

PURPOSE: A slim type speaker is provided to use a long elliptic shaped voice coil by fixing an intermediate supporting member on a vibration plate part.;CONSTITUTION: A slim type speaker comprises a vibration plate part(10), a first main body part(20), an intermediate supporting member(30), a voice coil(40), a magnetic circuit part(50), and a second body part. The slim type speaker includes a spring damper(70) and a lid part(80) in addition. The vibration plate part generates sound pressure through vibrations. The vibration plate part is generally mode of a polymer compound. The vibration plate part includes a coupling part(12) formed in the middle with a long length along the longitudinal direction of the vibration plate part. The coupling part is corresponding to a part combining with the intermediate supporting member.;COPYRIGHT KIPO 2012
