<p>A mobile device has an acoustic shock prevention circuit and prevents an acoustic shock unexpectedly occurring when receiver signals and speaker signals are output through a receiver-integrated speaker. The acoustic shock prevention circuit is preferably disposed between the receiver-integrated speaker and an audio processing unit is enabled in a receiver mode and disabled in a speaker mode. When the audio processing unit outputs audio signals partly exceeding a given output range, the enabled acoustic shock prevention circuit removes the exceeded parts of the audio signals.</p> |
