Abstract
An audio system for a vehicle includes: a hard disk drive for storing an audio data; an output element for converting the audio data to an electric signal and for outputting the electric signal to a reproducer; a memory; a position determination element for determining whether the vehicle is disposed in a predetermined area; an output data specification element for specifying the audio data outputting from the output element when the vehicle is disposed in the predetermined area; and a memorizing data control element for storing the specified audio data as a transfer data in the memory. The output element converts the transfer data and outputs the converted transfer data to the reproducer.
Claims10
An audio system for a vehicle comprising:
- a hard disk drive for storing an audio data;
- an output element for converting the audio data to an electric signal and for outputting the electric signal to a reproducer;
- a memory for storing a data;
- a position determination element for determining whether the vehicle is disposed in a predetermined area;
- an output data specification element for specifying the audio data outputting from the output element to the reproducer when the position determination element determines that the vehicle is disposed in the predetermined area;
- and
- a memorizing data control element for storing the specified audio data as a transfer data in the memory,
- wherein the output element converts the transfer data and outputs the converted transfer data to the reproducer when the position determination element determines that the vehicle is disposed in the predetermined area,
- wherein the output element switches from outputting of the electric signal to outputting of the converted transfer data when the position determination element determines that the vehicle is disposed in the predetermined area, and
- wherein the output element automatically without user intervention performs mute control for reducing noise when the output element switches from the outputting of the electric signal to the outputting of the converted transfer data.
A navigation device for a vehicle comprising:
- a hard disk drive for storing an audio data;
- a speaker for reproducing the audio data;
- a controller for converting the audio data to an electric signal and for outputting the electric signal to the speaker;
- a volatile memory;
- and
- a position detector for detecting a current position of the vehicle,
- wherein the controller determines whether the vehicle is disposed in a predetermined area based on the current position of the vehicle,
- wherein the predetermined area has an altitude equal to or higher than a predetermined altitude,
- wherein the controller specifies the audio data outputting from the controller to the speaker when the controller determines that the vehicle is disposed in the predetermined area,
- wherein the controller stores the specified audio data as a transfer data in the volatile memory,
- wherein the controller converts the transfer data and outputs the converted transfer data to the speaker when the controller determines that the vehicle is disposed in the predetermined area,
- wherein the controller stops operating the hard disk drive when the controller determines that the vehicle is disposed in the predetermined area,
- wherein the controller switches from outputting of the electric signal to outputting of the converted transfer data when the controller determines that the vehicle is disposed in the predetermined area, and
- wherein the controller automatically without user intervention performs mute control for reducing noise when the controller switches from the outputting of the electric signal to the outputting of the converted transfer data.
