Thin speaker and method of manufacturing the speaker |
摘要 |
A thin speaker having a magnetic circuit ( 2 ) disposed at the front of a cone-like diaphragm, wherein an internal magnetic type magnetic circuit ( 2 ) and a vibration system are supported by a sufficiently strong frame formed of two pieces having an outline of generally disk-shape and partly overlapped concentrically with each other, the acoustic characteristics are prevented from being deteriorated by preventing support bodies ( 7, 7 A) for the magnetic circuit ( 2 ) from covering the forward of the sound emitting face of the cone-like diaphragm ( 3 ), and speaker component parts are formed so as to be assembled by stacking on one jig ( 1 ) from one direction with a specified procedure, whereby an assemblability can be improved.
