PURPOSE: An ear-phone device is provided to compressively support a damper by a second housing which is combined with a first housing of a receiver, thereby reducing costs by eliminating a separate part for supporting the damper. CONSTITUTION: A jack is connected to an acoustic-apparatus or a communications device. One side and the other side of a code(120) are respectively connected to the jack and a receiver. A microphone, which is a transmitter, is installed in the middle of the cord. A housing(210) comprises a first housing(211) and a second housing(215). A damper(230) is compressed by the second housing and supports a speaker. |
