Method and device for setting output volume of audio signal to prevent acoustic shock in mobile terminal
First Claim
1. A method for setting an output volume of an audio signal in a mobile terminal to prevent acoustic shock, comprising the steps of:
- detecting an incoming call as being a video call;
outputting an audio signal received in relation to the video call in a safe speaker mode limiting a volume level when the call is connected; and
changing the current safe speaker mode to an original speaker mode when a user inputs a request for adjusting an output volume of the audio signal.

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.

8. A method for setting an output volume of an audio signal in a mobile terminal to prevent acoustic shock, comprising the steps of:
-
detecting an incoming call as being a voice call;
outputting an audio signal received in relation to the voice call in a receiver mode at a volume level not higher than a predetermined level when the call is connected; and
changing the current receiver mode to a speaker mode when a user inputs a request for adjusting an output volume of the audio signal. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A mobile terminal capable of setting an output volume of an audio signal to prevent acoustic shock, comprising:
-
an RF unit for detecting an incoming call;
a control unit for connecting a call when a user inputs a request for call connection corresponding to the incoming call, for outputting an audio signal received with the call connection at a reference volume level preset to limit an output volume, and for canceling the limiting of the volume level when the user inputs a request for adjusting an output volume of the audio signal; and
a voiceband signal processor for outputting the audio signal at the reference volume level when the call is connected under the control of the control unit, and for outputting the audio signal at an original volume level when the limiting of the volume level is cancelled. - View Dependent Claims (16, 17, 18, 19)
