PURPOSE: A combination mobile telephone and microphone for recognizing sound by computer is provided to use two functions of a telephone and a microphone by adapting the digital communication method of 900MHz. CONSTITUTION: In a standby mode, an audio signal from the speaker jack of a computer(10) is outputted via the speaker(14) of a base-set(12). If a call is received, the standby mode is switched to a call mode, so that a signal is transmitted to a mobile handset(16). Then the handset(16) is used as a telephone. In the other hand, by using a mike button(22), the sound inputted from the mike(19) of a headset(17) is converted into a digital signal, modulated and transmitted to the base-set(12) via an antenna(24). The received signal is demodulated and converted into an audio signal, and inputted in the computer(10) via a mike jack.
