Volume control of aural guidance of vehicle route guidance apparatus
First Claim
1. A vehicle route guidance apparatus which selectively outputs route guidance aurally through one loudspeaker, comprising:
- a voice generation section which selectively generates a guidance voice signal for route guidance through only one of a plurality of loudspeakers of an audio apparatus whenever selective route guidance is needed;
volume setting means being responsive to external operation, for setting a predetermined guidance voice signal level;
guidance voice adjustment means responsive to said volume setting means for adjusting a level of said guidance voice signal to said predetermined guidance voice signal level and for outputting an adjusted guidance voice signal;
test voice means for selectively outputting a test guidance voice signal through said guidance voice adjustment means to said only one loudspeaker when a predetermined period of time has passed after said predetermined guidance voice signal level is set by said volume setting means;
a circuit change switch for switching an input to said only one loudspeaker between an output signal from said audio apparatus and either said adjusted guidance voice signal or the adjusted test guidance voice signal; and
a control section which controls the switching of said circuit change switch, said control section controlling said guidance voice adjustment means independently from a volume control means controlling a level of said output signal from said audio apparatus.

Abstract
An apparatus to facilitate volume control for route aural guidance. When supplying a guidance voice to a loudspeaker 34a, a voice control section 30 disconnects the loudspeaker 34a from audio and outputs the guidance voice through the loudspeaker. A volume control screen is displayed on a display section 28 where the user adjusts the volume by touching the screen. When the voice control section 30 switches a signal to the loudspeaker 34a, a mute circuit 40a is operated to mute the voice output before the voice is output through the loudspeaker 34a. When the user terminates volume adjustment, the voice control section 30 outputs a voice for volume confirmation or check at the adjusted volume through the loudspeaker 34a. The user can check the adjusted volume at this time.

10. A vehicle route guidance apparatus which selectively outputs route guidance aurally through a loudspeaker, comprising:
-
a voice generation section which selectively generates a guidance voice signal for route guidance through only one of a plurality of loudspeakers of an audio apparatus whenever selective route guidance is needed; volume setting means being responsive to external operation, for setting a predetermined guidance voice signal level, said volume setting means including voice-stopping means for setting said predetermined guidance voice signal level at an inaudible level when an OFF key is operated; guidance voice adjustment means responsive to said volume setting means for adjusting a level of said guidance voice signal to said predetermined guidance voice signal level and for outputting an adjusted guidance voice signal; test voice means for selectively outputting a test guidance voice signal through said guidance voice adjustment means to said only one loudspeaker when a predetermined period of time has passed after setting said predetermined guidance voice signal level by said volume setting means; a circuit change switch for switching an input to said loudspeaker between an output signal from said audio apparatus and either said adjusted guidance voice signal or the adjusted test guidance voice signal; and control means for switching said circuit change switch to input either said adjusted guidance voice signal or said adjusted test guidance voice signal to said loudspeaker when said respective guidance voice signal or said test guidance voice signal is to be output through said loudspeaker, and for switching said circuit change switch to input said output signal from said audio apparatus when said guidance voice and said test guidance voice are not to be output through said loudspeaker, said control means independently controlling said guidance voice adjustment means separate from a volume control for a level of said output signal from said audio apparatus.

11. A vehicle route guidance apparatus which selectively outputs route guidance aurally through a loudspeaker, comprising:
-
a voice generation section which selectively generates a guidance voice signal for route guidance whenever selective route guidance is needed; volume control key means responsive to external operation, for setting a predetermined guidance voice signal level; guidance voice adjustment means responsive to said volume control key means for adjusting a level of said guidance voice signal to said predetermined guidance voice signal level and for outputting an adjusted guidance voice signal; a circuit change switch for switching an input to said loudspeaker between an output signal from an audio apparatus and said adjusted guidance voice signal; control means for switching said circuit change switch to input said adjusted guidance voice signal to said loudspeaker when said guidance voice signal is to be output through said loudspeaker, and for switching said circuit change switch to input said output signal from said audio apparatus when said guidance voice is not to be output through said loudspeaker, said control means independently controlling said guidance voice adjustment means separate from a volume control for a level of said output signal from said audio apparatus; test voice means for selectively outputting a predetermined test guidance voice signal through said guidance voice adjustment means to said loudspeaker when a predetermined period of time has passed subsequent to setting said predetermined guidance voice signal level by said volume control key means. - View Dependent Claims (12)
