Abstract
A hands-free device comprises a receiver having a speaker enclosed therein, a hose having one end coupled to the receiver, an enclosure at the other end of the hose and including a hole through the surface, a plug, and a first cord having one end coupled to the plug and the other end coupled to the speaker. Signals from an external communication device coupled to the plug is sent to the speaker through the first cord. The signals are then converted into voice in the speaker prior to transmitting to the enclosure through the hose. Finally, voice is outputted from the hole. Receiver is disposed away from the brain. Hence, the brain is not subject to electromagnetic wave generated by receiver while telephoning.
