<p>The present invention relates to a wireless hands-free system of cellular phone, more particularly to a wireless hands-free system of cellular phone, capable of being connected to any cellular phone easily, being used qualitatively without directly handling the body of a cellular phone, and lengthening the life span of its battery by reducing power consumption greatly due to a design of low power operated according to a transmitting-receiving condition. The system includes: a phone body with an earphone/microphone terminal; a main-device operated by a battery incorporated in itself, connected to said earphone/microphone terminal of said phone body, and adapted to input/output sound signals, and receive/transmit the sound signals thus input/output by wireless; and sub-device operated by a battery incorporated in itself, connected to said main-device by wireless, and adapted to receive/transmit sound signals, and input/output the sound signals thus received/transmitted to/from an earphone/microphone through users. <IMAGE></p> |
