摘要

A Bluetooth headset assembly for a mobile phone is disclosed. The assembly includes a headset in which a Bluetooth block is embedded in a circuit board. The Bluetooth block includes: a radio frequency transceiver receiving a signal from a mobile phone via the Bluetooth antenna; a digital signal processor processing the received signal; a controller controlling the digital signal processor; and an audio interface, such that the Bluetooth block transmits a reproduced audio signal from the audio interface to right/left earphones. The Bluetooth headset assembly includes: a selection unit for receiving an output signal from the earphone or an audio signal from an external audio device via a bypass path, and using the received signal as an input signal; and an FM transmitter block including a second audio interface, an FM converter, and an RF transmitter, such that the bypassed output signal is transmitted to an FM receiver.
