ADJUSTING ACOUSTIC SPEAKER OUTPUT BASED ON AN ESTIMATED DEGREE OF SEAL OF AN EAR ABOUT A SPEAKER PORT
First Claim
1. A method of adjusting the acoustic output of a speaker, comprising:
- detecting touch contact between an ear and at least one touch sensor in fixed relation to a speaker port for the speaker;
based on said detecting, estimating a degree of seal of said ear about said speaker port; and
based on the estimated degree of seal, adjusting the acoustic output of the speaker,wherein said estimating estimates a degree of seal based upon a size, in relation to a threshold size, of an arc over which said touch contact is substantially continuous, the arc being of a notional circle that is concentric with the speaker port.

Abstract
A degree of seal of an ear about a speaker port may be estimated by detecting touch contact between the ear and at least one touch sensor in fixed relation to the speaker port. The degree of seal is estimated based on the detected touch contact. Based upon the estimated degree of seal, the acoustic output of the speaker may be adjusted. The adjustment may compensate for perceived changes to the quality of the acoustic output resulting from the degree of seal. The at least one touch sensor may be a plurality of touch sensors spaced around the speaker port. Each sensor may have a truncated wedge shape, with a narrow end closest to the speaker port. Upon receipt of user input indicative of a high degree of ear seal, a sample of the sensor(s) may be taken and stored for using during future estimation of the degree of seal.

6. An electronic device comprising:
-
a housing having a speaker port; a speaker within said housing for providing acoustic output through said speaker port; at least one touch sensor in fixed relation to said speaker port; and a processor operable to; receive data representing touch contact between an ear and said at least one touch sensor; based on the received data, estimate a degree of seal of said ear about said speaker port; and based on the estimated degree of seal, adjust the acoustic output of the speaker, wherein said estimating estimates a degree of seal based upon a size, in relation to a threshold size, of an arc over which said touch contact is substantially continuous, the arc being of a notional circle that is concentric with the speaker port. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. A non-transitory machine-readable medium storing instructions which, when executed by a processor of an electronic device having a speaker and at least one touch sensor in fixed relation to a speaker port for the speaker, causes said processor to:
-
receive data representing touch contact between an ear and said at least one touch sensor; based on the received data, estimate a degree of seal of said ear about said speaker port; and based on the estimated degree of seal, adjust the acoustic output of the speaker, wherein said estimating estimates a degree of seal based upon a size, in relation to a threshold size, of an arc over which said touch contact is substantially continuous, the arc being of a notional circle that is concentric with the speaker port. - View Dependent Claims (16, 17, 18)
