Abstract
The invention provides an interphone with a FM emission function and an implementing method thereof. A communication connection is established between an interphone and a vehicle-mounted background server in order that the interphone acquires an audio signal from the vehicle-mounted background server via a communication network, converts the acquired audio signal into a FM frequency-modulated signal, and then emits the frequency-modulated signal so as to provide the interphone with the FM emission function. The interphone and the implementing method thereof provide a network music function for a driver, convert voice talkback information into a FM audio signal and emit the FM audio signal. A vehicle-mounted radio plays the voice talkback information and real-time road condition information received from the vehicle-mounted background server. As a result, the intellectuality of the interphone is improved and driving convenience is provided for the driver.
