Abstract

A vehicle multimedia navigation apparatus with dual audio output has two sets of audio output channels or more. At least one set of the audio output channels is connected to an independent speaker set and one set or more is connected to an audio input device of a vehicle stereo which amplifies and broadcast through the vehicle stereo speaker set. Users can get navigation instructions from the independent speaker set or select the vehicle stereo to execute navigation or simultaneously broadcast multimedia audio.

Claims

1. A vehicle multimedia navigation apparatus having dual audio output comprising two sets of audio output channels or more under a_navigation system architecture, wherein:

at least one set of the audio output channels is connected to an independent speaker set and another one set or more of the audio output channels is connected to a vehicle stereo which amplifies and broadcast through a vehicle stereo speaker set such that users are allowed to select the independent speaker set to broadcast navigation speech information or select the vehicle stereo to execute navigation or simultaneously broadcast multimedia audio.

2. The vehicle multimedia navigation apparatus of claim 1, wherein the another one set or more of the audio output channels is connected to an audio input device of the vehicle stereo to broadcast music through the vehicle stereo speaker set and output multimedia audio programs corresponding to the navigation system.

3. The vehicle multimedia navigation apparatus of claim 1, wherein the another one set of the audio output channels is connected to an audio input device through an extension line.

4. The vehicle multimedia navigation apparatus of claim 2, wherein the audio input device of the vehicle stereo is an audio input terminal.

5. The vehicle multimedia navigation apparatus of claim 1, wherein the audio output channels are connected to a radio emission device to modulate audio signals transferred from the audio output channels.

6. The vehicle multimedia navigation apparatus of claim 5, wherein the radio emission device modulates and emits frequency modulation (FM) signals.

7. The vehicle multimedia navigation apparatus of claim 5, wherein the radio emission device modulates and emits amplitude modulation (AM) signals.

8. The vehicle multimedia navigation apparatus of claim 5, wherein the radio emission device modulates and emits infrared signals.

9. The vehicle multimedia navigation apparatus of claim 5, wherein the radio emission device modulates and emits Bluetooth radio signals.

10. The vehicle multimedia navigation apparatus of claim 1, wherein the control unit controls output sound of the audio output channels at a reduced volume or to stop broadcasting temporarily.

11. The vehicle multimedia navigation apparatus of claim 1, wherein the control unit controls the multimedia audio and the navigation speech information to output through a same audio output channel.

12. The vehicle multimedia navigation apparatus of claim 1, wherein the navigation system architecture further includes an audio processor and a plurality of audio processing devices that have output ends connecting respectively to the audio output channels in an one-on-one fashion.

13. The vehicle multimedia navigation apparatus of claim 12, wherein the audio processing devices are connected to an audio switching device to switch control of the audio output channels.
