A first microphone is used as a main part micro for the input of the acoustic signal. A second microphone is used as a sub microphone for the input of the acoustic signal. The acoustic signal is input through the first and second microphones and the voice and noises processing unit(20) removes interference. A service selecting unit(50) converts the route of the signal inputted from the voice and noises processing unit. A voice record function processing unit(60) encodes the signal transmitted through the service selecting unit. |
