Appeal No. 2006-1777
Application No. 10/206,704
BACKGROUND
The invention relates to electrical impedance based audio compensation in
electrical devices that are subject to variable acoustic impedance (e.g., wireless
communication devices). Representative claim 1 is reproduced below.
1. A method in an electronics device having an ear-mounted sound
transducer, comprising:
determining a change in an electrical parameter that changes with
changes in an acoustic impedance of the sound transducer;
determining audio signal compensation based upon the change in
the electrical parameter;
dynamically compensating an audio signal sent to the sound transducer
based upon the audio signal compensation.
