<p><P>PROBLEM TO BE SOLVED: To provide an audio apparatus capable of preventing occurrence of noise in opening/closing. <P>SOLUTION: An audio apparatus includes a control unit which receives an operation voltage output from a power source unit and outputs an audio signal, and an amplifier which processes the audio signal received and transmits it to a speaker to reproduce sound. The audio apparatus further includes a first detection unit and a signal generation unit connected to the power source unit. When the power source unit is turned on, on the basis of a detection signal output from the first detection unit and a voltage output from the power source unit, the signal generation unit transmits a mute signal to the amplifier, and the amplifier stops output on the basis of the mute signal to stop reproducing the sound from the speaker. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
