Abstract

A wireless detachable conference telephone and particularly a conference telephone that has a plurality of wireless microphone seats detachable from a conference telephone main body. The conference telephone main body and the wireless microphone seats may be communicated through radio signals so that users can detach the microphone seats from the conference telephone main body and move the microphone seats closely to input audio voice so that poor conversation quality resulting from distant conference telephone may be prevented from happening.

Claims

1. A wireless detachable conference telephone, comprising:

a conference telephone main body having at least one housing chamber formed on the peripheral rim thereof and a first radio unit located therein; and

at least one microphone seat movably housed in the housing chamber having a second radio unit to communicate with the first radio unit for transmitting and receiving radio signals therebetween.

2. The wireless detachable conference telephone of claim 1, wherein the first radio unit includes a first antenna, a first transmitter and receiver unit, a first modulating/demodulating unit, and an audio output processing unit;

the first antenna being for the first transmitter and receiver unit to transmit or receive the radio signals;

the first transmitter and receiver unit transferring signals to radio waves for emitting through the first antenna or receiving selected radio signals through the first antenna;

the first modulating/demodulating unit modulating or demodulating the signals and forwarding the signals to the rear end first transmitter and receiver unit or the audio output processing unit for use; and

the audio output processing unit having an output linking to a speaker and telephone circuits for processing the modulated audio signals, and outputting through the speaker and the telephone circuits.

3. The wireless detachable conference telephone of claim 1, wherein second radio unit includes a second antenna, a second transmitter and receiver unit, a second modulating/demodulating unit, and an audio input processing unit;

the second antenna being for the second transmitter and receiver unit to transmit or receive the radio signals;

the second transmitter and receiver unit transferring signals to radio waves for emitting through the second antenna or receiving selected radio signals through the second antenna;

the second modulating/demodulating unit modulating or demodulating signals and forwarding the signals to the second transmitter and receiver unit for use; and

the audio input processing unit having an input linking to a microphone for modulating audio signals input by users and forwarding to the rear end second modulating/demodulating unit for use.
