Abstract

A portable music player includes an audio circuit for processing input audio signals to generate output audio signals and a set of speakers connected to said audio circuit for converting output audio signals into audible signals. A headset interface provides means for connecting a headset to said audio circuit for playback of audio signals through said headset. Audio profiles for said speakers and said headset are stored in memory. A control circuit selects an audio profile depending on whether a headset is connected with said headset interface, and configures said audio circuit based on the selected profile.

Claims

1. A portable music player comprising:

memory for storing respective audio profiles for two or more listening modes; and

a control circuit to select an audio profile depending on a selected listening mode, and to configure an audio circuit based on the selected profile.

2. The portable music player of claim 1 wherein one of said listening modes comprises a speaker mode wherein audio is output to internal speakers and one of said listening modes is a headset mode wherein audio is output to a headset.

3. The portable music player of claim 2 further comprising a detection circuit connected to the control circuit to detect the connection of said headset, said control circuit responsive to a signal output by said detection circuit to switch between said speaker mode and said headset mode.

4. The portable music player of claim 1 wherein said audio profiles store one or more audio settings for configuring said audio circuit.

5. The portable music player of claim 4 wherein said audio settings include a setting for at least one audio enhancement effect.

6. The portable music player of claim 5 wherein said audio enhancement effect includes at least one of stereo widening, bass enhancement, and audio equalization.

7. The portable music player of claim 4 wherein said audio settings include a call setting controlling audio playback responsive to an incoming call.

8. The portable music player of claim 7 wherein options for said call setting include a fade option for gradually muting and resuming audio playback at the beginning and end of a call, respectively.

9. The portable music player of claim 7 wherein options for said call setting include a background option for reducing volume of said audio playback during said call.

10. A method of configuring an audio circuit for a portable audio device, said method comprising:

storing audio profiles in memory for two or more listening modes;

selecting an audio profile for a selected listening mode; and

configuring said audio circuit based on the selected audio profile.

11. The method of claim 10 further comprising processing input audio signals with said audio circuit to generate output audio signals.

12. The method of claim 10 wherein one of said listening modes comprises a speaker mode wherein audio is output to internal speakers and one of said listening modes is a headset mode wherein audio is output to a headset.

13. The method of claim 12 wherein selecting an audio profile for a selected listening mode comprises selecting a speaker profile when said speaker mode is enabled and selecting said headset profile when said headset mode is enabled.

14. The method of claim 13 further comprising:

determining whether said headset is connected; and

selecting said speaker mode or said headset mode depending on whether said headset is connected.

15. The method of claim 10 wherein said audio profiles store one or more audio settings for configuring said audio circuit.

16. The method of claim 15 wherein said audio settings include a setting for at least one audio enhancement function.

17. The method of claim 16 wherein said audio enhancement function includes one of stereo widening, bass enhancement, and audio equalization.

18. The method of claim 15 wherein said audio settings include a call setting controlling audio playback responsive to an incoming call.

19. The method of claim 18 wherein options for said call setting include a fade option for gradually muting and resuming audio playback at the beginning and end of a call, respectively.

20. The method of claim 18 wherein options for said call setting include a background option for reducing volume of said audio playback during said call.

21. A portable music player comprising:

an audio circuit for processing input audio signals to generate output audio signals;

a speaker connected to said audio circuit for converting output audio signals into audible signals;

a headset interface for connecting a headset to said audio circuit;

memory for storing respective audio profiles for said speaker and said headset; and

a control circuit to select an audio profile depending on whether a headset is connected with said headset interface, and to configure said audio circuit based on the selected audio profile.

22. The portable music player of claim 21 further comprising a detection circuit to detect the connection of said headset with said headset interface and to generate a status signal for input to said control circuit.

23. A portable music player comprising:

a detection circuit configured to detect the connection of a headset to the portable music player; and

a control circuit connected to the detection circuit, wherein said control circuit configures an audio circuit in the portable music player based on an output signal by the detection circuit.

24. The portable music player of claim 23 wherein the control circuit configures the audio circuit to implement an audio enhancement effect.

25. The portable music player of claim 24 wherein the audio enhancement effect includes at least one of a stereo widening, bass enhancement, and audio equalization.

26. A method of configuring an audio circuit for a portable audio device, said method comprising:

detecting the connection of a headset to the portable audio device; and

configuring an audio circuit in the portable audio device depending on whether the headset is connected.

27. The method of claim 26 wherein configuring the audio circuit comprises configuring the audio circuit to implement an audio enhancement effect.

28. The method of claim 27 wherein the audio enhancement effect includes at least one of a stereo widening, bass enhancement, and audio equalization.
