Abstract
A mobile terminal with a function for setting an output volume of an audio signal to prevent acoustic shock is disclosed. In the mobile terminal, a receiver is integrated into a speaker. The speaker limits the initial output volume of an audio signal to a predetermined level. The mobile terminal provides a menu for setting an output volume of an audio signal. The menu enables a user to select either to maintain the currently limited volume level or to change to a volume level set for a speaker mode. Since an audio signal received with the connection of an incoming call is output at a predetermined reference volume level, acoustic shock caused by unexpectedly high-level of sound volume can be prevented.
