<p>A device for electrically connecting a microphone mounted on a flit cover to an audio circuit of a telephone body. The flip cover is detachable from the telephone body when an excessive force is applied thereto. A hinge apparatus includes two hinge modules each including a hinge housing, a hinge shaft having a protrusion at an end and a shaft at another end, being assembled into the hinge housing; conductive means fixedly pressed into a through hole formed along an axis of the hinge shaft; a cam hinge having opposing protrusions and opposing indents formed alternately at one side, engaging with the hinge shaft, and a through hole formed along the axis of the hinge shaft; a hinge cover mounted so as to cover an end of the hinge housing, the hinge cover having a through hole formed along the axis of the hinge shaft; and a coil spring intervening between the cam hinge and the hinge cover to provide an elastic force. The flip cover includes a first connection terminal having a plane surface, a curved surface and a tension part, wherein the tension part maintains electrical contact with the conductive means; and a microphone mounted on the flip cover.</p> |
