The present invention relates to a control apparatus and method for a wireless headset that receives a voice signal output from various voice output devices such as a compact disc (CD) player and a cassette tape player and the like through short-range communication and outputs the same to a speaker.

With the development of communication technology, various near field communication technologies have been developed to perform wireless communication in the near field. One of the short range communication technologies is known as Bluetooth. The Bluetooth continues to evolve since version 1.0 was released as an official standard in July 1999. Bluetooth has a maximum data rate of 1Mbps (the effective transmission rate considering packet headers is 433.9kbps in both directions, 723.2kbps in one direction, and 57.6kbps in the other). The transmission distance is within 10m when the transmission power is 1㎽, and the maximum transmission power is specified as 100㎽.

In addition, Bluetooth sets 79 channels with 1MHz bandwidth in 2.4000∼2.4835㎓ ISM (Industrial Scientific Medical) band that user can use unlicensed, and uses frequency hopping spread spectrum in 1600 seconds The data is transmitted by changing the channel about once.

As Bluetooth uses a frequency hopping method, data can be transmitted accurately even in a noisy wireless environment, and frequency interference is avoided by transmitting and receiving a predetermined packet and hoping at a frequency of a new channel.

Therefore, Bluetooth communication hops faster than other systems operating in the same frequency band and can transmit data more stably using shorter packets.

In addition to the above-mentioned Bluetooth, various short-range communication technologies are known, including Zigbee, Ultra Wide Band (UWB), and wireless local area network (LAN).

As the near field communication technology is mounted on the headset, the headset receives the voice signal output by the voice output device through short range communication and outputs the speaker to the speaker without a wired connection to the voice output device outputting the voice signal.

Meanwhile, as a user demands various functions for a headset, a detachable headset has recently emerged. The detachable headset includes first and second speaker bodies having built-in speakers for outputting audio signals of L and R channels, respectively, and a connecting member detachably connecting the first and second speaker bodies.

In addition, the connection member may be put on the head, and the first and second speaker bodies may be positioned at the ear part, so that the voice signal output from the voice output device may be heard.

Users requiring simplicity separate the first and second speaker bodies from the connection member of the detachable headset. The separated first and second speaker bodies are located at the left and right ears of the user, respectively, and listen to the audio signals of the L and R channels output from the voice output device. In addition, two people using the separated first and second speaker bodies may listen to a voice signal output from the voice output device.
