WIRELESS TRANSCEIVER APPARATUS
The present invention relates to a wireless transceiver apparatus, especially a wireless transceiver apparatus having a skin-touch microphone and a wireless earpiece.
Traditional mobile devices employ a microphone that picks up sounds waves transmitted through the air to receive a user's voice; therefore, background noise can and does seriously affect communication quality and efficiency. Furthermore, cellular phones on the market employ lo an earpiece and microphone to transmit signals. Most earpieces and microphones in the market rely on wired electrical circuit to transmit signals. The wired earpieces and microphones cause inconvenience to users. The present invention uses a cordless mechanism - a wireless transceiver apparatus with a skin-touch microphone and a wireless earpiece - to overcome the inconvenience.
An objective of the invention is to use a wireless transceiver apparatus to transmit background noise-free voice signals between a user and a communication unit. This wireless transceiver apparatus comprises: a wireless transceiver unit, a switch unit, a radio-receiving unit and a communication unit. The transceiver unit turns human voice into a first signal, and the communication unit is able to emit a second signal.
When the wireless transceiver apparatus is in a first state, the switch unit is able to receive the first signal in the form of a radio transmission from the transceiver unit and pass the received signal to the communication unit.
When the wireless transceiver apparatus is in a second state, the switch unit is able to receive the second signal from the communication unit and pass the received signal to the transceiver unit, which then finally passes them to the radio-receiving unit.
The invention will be further described by way of example with reference to the accompanying drawings, in which: Fig. 1 shows a wireless transceiver apparatus according to a first embodiment of the present invention.

Furthermore, the present invention also contemplates that the switch unit and the communication unit can be combined to achieve the convenience and smaller size required for a mobile device. For example, a "Bluetooth" wireless module can be built into a cellular phone. This will overcome the inconvenience of using a traditional hands-free headset that must be linked to a cellular phone by a cumbersome wire.
