An earphone, which is constructed of a housing (12), and a transducer (14) comprising a magnetic circuit (16) received in the housing and a diaphragm (18) magnetically coupled to the magnetic circuit. The diaphragm has a diameter substantially equal to the housing. A resilient support member (22) is attached in relation to the housing and aligned with the diaphragm. In use, the resilient member is compressed, inserted into the user's auditory meatus and allowed to re-expand so as to provide a high fidelity sonic connection between the diaphragm of the earphone and the user's eardrum. In one embodiment a protector plate is attached to the housing and covers the diaphragm. The support member is then affixed to the protector plate. The support member is generally cylindrical in shape, having a longitudinal axis oriented generally normal to the diaphragm. The support member includes an axial opening which runs substantially the length of the member. |
