MICRO SPEAKER DIAPHRAGM, A METHOD THEREOF AND A MICRO SPEAKER COMPRISING THE SAME DIAPHRAGM, HAVING HUMIDITY RESISTANCE AND CHEMICAL RESISTANCE BY SEALING A RIGID MEMBER AT THE CENTER OF A HIGHLY POLYMERIZED COMPOUND FORMING A VIBRATION PLATE

摘要

PURPOSE: A micro speaker diaphragm, a method thereof and a micro speaker comprising the same diaphragm are provided to simplify a manufacturing process by removing a deformation, a blanking, and an adhesion process.;CONSTITUTION: A first vibration member(111) is comprised of an edge part(111a) and a central part(111b). A rigid member(121) is attached to the central part of the first vibration member. The rigid member is formed with a rigid material having lower specific gravity than that of the first vibration member. A second vibration member(122) is attached to the upper part of the first vibration member including the rigid member. The second vibration member seals the rigid member, and the first vibration member is formed as a polymer film-type.;COPYRIGHT KIPO 2010
