Streophonic apparatus having multiple switching function and an apparatus for controlling sound signal
First Claim
1. A stereophonic apparatus having multiple switching function, comprising;
- an audio signal generating unit for generating an audio signal;
a sound signal controlling unit for outputting a sound signal to a sound signal input terminal of an external sound apparatus and controlling path of a sound signal output from a sound signal output terminal of said external sound apparatus;
a mixing unit for generating a mixed sound signal by mixing an audio signal input from said audio signal generating unit and a sound signal input through said sound signal controlling unit;
an audio amplifying unit for amplifying a mixed sound signal input from said mixing unit; and
an output unit for outputting a mixed sound signal amplified by said audio amplifying unit.

17. An apparatus for controlling sound signal, coupled to a stereophonic apparatus and a mobile phone, comprising;
-
a microphone unit, having one end connected to a sound signal input terminal of said mobile phone and other end grounded, which converts a voice signal into a sound signal and transmits it said sound signal input terminal of said mobile phone;
a calling mode conversion switch, having one end connected to said sound signal input terminal of said mobile phone and other end grounded, which switches an operating condition of said mobile phone to a calling mode or a call waiting mode; and
a secret call switch for switching a sound signal input from said sound signal output terminal of the mobile phone to a mixing unit of said stereophonic apparatus or a secret call output unit. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
