Abstract
An ear piece transducer having a housing incorporating therein an electroacoustic transducer element, the housing being inserted into a concave portion of an auricle, and a ring member having resiliency sufficient to enable it to be attached to the outer peripheral portion of the housing, the ring member being formed so as to be thickest in one radial direction.

An ear piece transducer comprising:
- (a) a housing incorporating therein an electroacoustic transducer element, said housing being formed such that it is inserted into a concave portion of an auricle;
- and
- (b) an annular ring member attached to the outer peripheral portion of said housing, said annular ring member being formed of varying annular width thickness such that it is widest in one radial direction from the center of said housing, whereby at least a portion of said annular ring member is made of a resilient material.
An ear piece transducer for use in a human auricle having tragus and antitragus side, comprising:
- (a) a housing incorporating therein an electroacoustic transducer element, said housing being formed such that it is inserted into a concave portion of an auricle and having a back surface shaped so that upon such insertion at least two points of said back surface are supported by said tragus and antitragus sides of said auricle respectively;
- (b) a protecting plate mounted on said housing on the side of said housing which faces said concave portion of said auricle;
- and
- (c) an annular ring member attached to the outer peripheral portion of said housing being formed of varying annular width thickness such that it is widest in one radial direction from the center of said housing, whereby at least a portion of said annular ring member is made of a resilient material.
