Abstract

A mobile electronic device is provided. The mobile electronic device includes a housing having an ear-facing surface. Also, the mobile electronic device includes an audio transducer disposed within the housing. Further, the mobile electronic device includes an acoustic channel coupled between the audio transducer and the ear-facing surface for transmitting sound waves produced by the audio transducer to external of the ear-facing surface, wherein the audio-transducer having an audio-transmitting plane disposed at an angle other than parallel relative to the ear-facing surface.

Claims

1. A mobile electronic device comprising:

a housing having an ear-facing surface;

an audio transducer disposed within said housing; and

an acoustic channel coupled between said audio transducer and said ear-facing surface for transmitting sound waves produced by said audio transducer to external of said ear-facing surface, wherein said audio-transducer having an audio-transmitting plane disposed at an angle other than parallel relative to said ear-facing surface.

2. The mobile electronic device of claim 1 wherein said mobile electronic device is a mobile telephone.

3. The mobile electronic device of claim 1 wherein said mobile electronic device is a personal digital assistant.

4. The mobile electronic device of claim 1 wherein said mobile electronic device is an internet tablet.

5. The mobile electronic device of claim 1 wherein said audio-transmitting plane of said audio transducer is at a less-than ninety degree angle relative to said ear-facing surface of said mobile electronic device.

6. The mobile electronic device of claim 1 wherein said audio-transmitting plane of said audio transducer is at a forty-five degree angle relative to said ear-facing surface of said mobile electronic device.

7. The mobile electronic device of claim 1 wherein said audio-transmitting plane of said audio transducer is perpendicular to said ear-facing surface of said mobile electronic device.

8. The mobile electronic device of claim 1 wherein a magnetic field produced by said audio transducer is shaped using a magnetic-field shaping component to guide said magnetic field toward said ear-facing surface.

9. A method for creating a mobile electronic device, comprising:

providing a housing having at least an ear-facing surface and an acoustic channel;

providing an audio transducer; and

arranging said audio transducer at a position in which an audio-transmitting plane of said audio transducer is at an angle other than parallel relative to said ear-facing surface, wherein said audio transducer is disposed within said housing and said acoustic channel is positioned between said audio transducer and said ear-facing surface for transmitting sound waves produced by said audio transducer to external of said ear-facing surface.

10. The method of claim 9 wherein said mobile electronic device is a mobile telephone.

11. The method of claim 9 wherein said audio-transmitting plane of said audio transducer is at a less-than ninety degree angle relative to said ear-facing surface of said mobile electronic device.

12. The method of claim 9 wherein said audio-transmitting plane of said audio transducer is at a forty-five degree angle relative to said ear-facing surface of said mobile electronic device.

13. The method of claim 9 wherein said audio-transmitting plane of said audio transducer is perpendicular to said ear-facing surface of said mobile electronic device.

14. The method of claim 9 further including shaping a magnetic field produced by said audio transducer using a magnetic-field shaping component to guide said magnetic field toward said ear-facing surface.

15. A mobile electronic device, comprising:

housing means;

means for producing sound; and

means for transmitting sound from said means for producing sound to external of an ear-facing surface of said housing means, wherein an audio-transmitting plane of said means for producing sound is at an angle other than parallel relative to said ear-facing surface of said housing means.

16. The mobile electronic device of claim 15 wherein said means for producing sound is an audio transducer.

17. The mobile electronic device of claim 15 wherein said means for transmitting sound is an acoustic channel.

18. The mobile electronic device of claim 15 wherein said audio-transmitting plane of said means for producing sound is at a forty-five degree angle relative to said ear-facing surface of said mobile electronic device.

19. The mobile electronic device of claim 15 wherein said audio-transmitting plane of said means for producing sound is perpendicular to said ear-facing surface of said mobile electronic device.

20. The mobile electronic device of claim 15 further including means for shaping a magnetic field generated by said means for producing sound.
