USING ACCELEROMETERS FOR LEFT RIGHT DETECTION OF HEADSET EARPIECES
First Claim
1. An earplug, comprisinga housing positionable with respect to the ear of a user,a speaker positioned with respect to the housing to provide sounds to the ear of a user,an accelerometer positioned with respect to the housing and configured to sense a predetermined direction,the housing configured to facilitate the tendency for a user to position the housing with respect to an ear with a portion of the housing facing a predetermined direction,whereby the relation of the downward direction to the predetermined direction with respect to an ear is indicative of the left or right ear with respect to which the housing is positioned.

Abstract
An earplug to provide sounds to a user'"'"'s ear includes a housing, a speaker in the housing, a reference location or direction indicator associated with the housing to identify a preferential orientation of the housing in a user'"'"'s ear, and an accelerometer configured to provide an output signal to distinguish and/or to identify in which ear respective earplugs are located. A method to distinguish and/or to identify in which ear respective earplugs are located includes orienting the earplugs in respective ears based on a reference, and using accelerometers to provide output signals distinguishing the left and right positioning of the respective earplugs.

1. An earplug, comprising
a housing positionable with respect to the ear of a user, a speaker positioned with respect to the housing to provide sounds to the ear of a user, an accelerometer positioned with respect to the housing and configured to sense a predetermined direction, the housing configured to facilitate the tendency for a user to position the housing with respect to an ear with a portion of the housing facing a predetermined direction, whereby the relation of the downward direction to the predetermined direction with respect to an ear is indicative of the left or right ear with respect to which the housing is positioned.

2. An earplug, comprising
a housing positionable with respect to the ear of a user, a speaker positioned with respect to the housing to provide sounds to the ear of a user, an accelerometer positioned with respect to the housing and configured to sense a predetermined direction, an electrical cable exiting the housing and configured to facilitate the tendency for a user to position the housing with respect to an ear with the electrical cable facing a predetermined direction, whereby the relation of the downward direction to the predetermined direction with respect to an ear is indicative of the left or right ear with respect to which the housing is positioned.
-
8. A method of determining which of two earplugs is positioned at which respective ear of a user, comprising,
positioning each of the earplugs at an ear such that at least a prescribed part of the earplug or a wire attached to the earplug faces a predetermined direction, determining whether for at least one of the earplugs the direction of a downward direction is relatively to the right or to the left of the predetermined direction with the earplug in use position at an ear as a representation of whether the earplug is in the left ear or the right ear.

11. An earplug apparatus for an audio headset, comprising a housing, a speaker, an accelerometer, and a reference identifier to indicate a preferred orientation of the housing with respect to an ear, and wherein the accelerometer and the reference identifier are cooperative when the earplug is in position to provide sounds to an ear to identify at which ear the earplug apparatus is located.
- 12. An earplug of a headset, including a housing positionable with respect to the ear of a user, a speaker positioned with respect to the housing to provide sounds to the ear of a user, an accelerometer positioned with respect to the housing and configured to sense a predetermined direction, the housing configured to facilitate the tendency for a user to position the housing with respect to an ear with a portion of the housing facing a preferential direction to distinguish from the predetermined direction, whereby the relation to the predetermined direction to the preferential direction with respect to an ear is indicative of the left or right ear with respect to which the housing is positioned in comparison to a similar earplug similarly in position with respect to the other ear of the user.
-
20. A sound recording method including placing each of a pair of earpieces of a headset in a respective left or right ear, automatically detecting which earpiece is in which ear, each earpiece including a microphone, the sounds recorded by respective microphones being identified with the respective left or right ear at which the sounds are received.
-
21. A sound recording system including a pair of earpieces positionable in or at respective ears of a user, an indicator indicating automatically in or at which of the ears the earpieces are located, a microphone in each earpiece to receive sounds, and circuitry configured to identify respective ears at which the respective sounds are received.
-
22. A self contained earplug, comprising
a housing, operating circuitry, a speaker, a control configured to control operation of the operating circuitry to provide signals to cause the speaker to produce output sounds, the housing including a device to retain the earplug with respect to an ear of a user, and a connection to a source of signals to produce such output sounds.
