Abstract

Aspects of a method and system for an audio speaker with proximity sensing are presented. Aspects of a system for audio signal processing may include a proximity detector that enables adjustment of audio volume of a speaker in a wireless communication system based on detection of a location of at least one object in relation to the speaker.

Claims

adjusting audio volume of a speaker in a wireless communication system based on detection of a location of at least one object in relation to said speaker.

2. The method according to claim 1, further comprising generating at least one of:

a voltage signal and a current signal, based on said location of said at least one object.

3. The method according to claim 2, further comprising generating said at least one of:

said voltage signal and said current signal, by emitting light and detecting a level of reflected said generated light.

4. The method according to claim 2, further comprising generating said at least one of:

said voltage signal and said current signal, by transmitting an electromagnetic signal and detecting a level of reflection of said transmitted electromagnetic signal.
