Abstract
A wireless mobile telephone capable of remitting picking up of an earphone in use-but combining with car hi-fi speakers, which mobile telephone applies an infrared transmission principle or a radio transmission principle to transmit its received and emitting signals to a car hi-fi set. Therefore, the car speakers can broadcast the sound of the other side of the mobile phone call in remitting picking up of the earphone. In this way, the mobile telephone not only has the advantage of remitting picking up of the earphone, but also can be extremely convenient in use by having no connecting wire between the mobile telephone and the car hi-fi set.
