Vibrating body for acoustic transducer and speaker device

摘要

A vibrating body for an acoustic transducer is provided, in which the high resonance frequency associated with inverse resonance can be outside the audible range and which can improve the acoustic characteristic of a speaker device. The vibrating body 1 for an acoustic transducer includes: a diaphragm 2 including a first vibrating part 2a and a second vibrating part 2b formed in proximity of the outer circumferential edge of the first vibrating part 2a; and an edge portion 3 formed in proximity of the outer circumferential edge of the diaphragm 2. In the vibrating body 1 for an acoustic transducer, first reinforcing portions 6a and 6b are formed so as to extend from the second vibrating part 2b to the edge portion 3 in a radial direction.

主权项

1. A vibrating body for an acoustic transducer comprising:
a diaphragm including:
a first vibrating part,a second vibrating part in the outer side of said first vibrating body, andan edge portion in outer side of said second vibrating part; and a reinforcing portion extending from said second vibrating part to said edge portion in a radial direction, wherein: said second vibrating part includes a first region having a straight outer circumferential part and a second region having a curved outer circumferential part; and said reinforcing portion is formed in said second region of said second vibrating part.
