According to the drawings, the helmet equipped with the hands-free transceiver of the present invention is largely composed of a hands-free means 2 and an adapter 3.

The hands-free means (2) is mounted inside the helmet (1) worn by the motorcycle driver to allow the user to make a phone call without directly holding the mobile phone (4), the first RF (Radio frequency) module 21, a switch 23, a first signal processor 22, a first pulse code modulation (PCM) unit 24, a speaker 25, a microphone 26, a battery 27 and the like.

The first RF module 21 communicates the digital signal with the adapter 3 connected to the cellular phone 4, and receives the wireless transmission signal transmitted from the adapter 3 to receive the first signal processor 22 at the rear end. And a signal output from the first signal processor 22, for example, a voice signal of a user, is wirelessly transmitted to the adapter 3 through an antenna.

The switch 23 is installed on the outside of the helmet 1 to enable the user's operation. The switch 23 is turned on and off according to the user's operation so that the hands free means 2 is turned on and off. It is preferable to install so as to be exposed to the outside of the side portion of the helmet 1 so that it can be freely manipulated while driving.

The first signal processor 22 processes the digital signals transmitted and received through the first RF module 21 and supplies them to the required components.

That is, the digital signal received through the first RF module 21 is demodulated to the original signal and output through the speaker 25, and the user's voice signal supplied from the first PCM unit 24 is output to the first RF module. Supply to (21), and drives the circuit in accordance with the on / off state of the switch (23).
