Abstract: A wireless transceiving apparatus for audio signals comprises a bluetooth transceiver for transmitting and receiving digital signals, a bluetooth base-band unit electrically connected to the bluetooth transceiver, a processing unit electrically connected to the bluetooth base-band unit, and a codec unit electrically connected to the processing unit. The processing unit includes a first processing module for cell phone signals and a second processing module for stereo signals, and the processing priority of the first processing module is higher than the processing priority of the second processing module. The codec unit comprises an input port capable of being connected to a sound-to-voltage transducer such as a microphone, and an output port capable of being connected to a sound output device such as a headphone. The bluetooth transceiver can be coupled to an electrical device via a bluetooth transmitter.

Abstract: A wireless audio transmitter is capable of converting audio signals into wireless Bluetooth signals. The transmitter comprises an ADC converting input analog audio signals into digital signals. A CPU outputs original data complying with Bluetooth communication protocols. The original data are sequentially processed by a Bluetooth base band processor and a Bluetooth RF processor, and are converted into RF signals. Finally, the RF signals are transmitted in a wireless microwave manner by an antenna.
