  • Patent number: 7529570
    Abstract: A folding cellular phone capable of adjusting the output or sensitivity of its microphone based on whether or not the cellular phone is folded. A detector outputs a detection signal indicating whether or not first and second housings are in their closed positions to a controller. When the detection signal output from the detector indicates that the first and second housings are in closed positions, the controller sets the gain of a variable amplifier, which amplifies the output of a microphone, higher than that when the detection signal output from the detector does not indicate that the first and second housings are in closed positions.
