Abstract

This invention relates specifically to a stereo Bluetooth headset but potentially to any wireless headset or headphones. This invention involves mechanical, electrical and acoustical fields. Currently, wireless headsets and headphones cannot be used in-flight due to FAA regulations. Owners of wireless headsets and headphones are forced to carry corded versions to use when traveling by air. This invention involves the integration of a connector and electrical circuit into a wireless headset (or headphones) that allows the user to plug a cord into the headset, which is connected to an audio source, automatically disabling the wireless caabilities of the headset. By disabling wireless functions and providing for corded audio input, a device can be used in passenger aircraft. This feature is referred to as "flight mode." When implemented in a stereo wireless headset, an additional feature called “dual purpose mic" is proposed with this invention. In addition to disabling the wireless capabilities when a cord is connected to a stereo wireless headset, the headset microphone automatically switches from communication mode (assumed to capture voice) to noise-cancellation mode where it measures background noise for cancellation in the receive paths to provide an improved listening experience in noisy environments. In other words, the stereo wireless headset would automatically become noise canceling headphones when a cord is connected and" flight mode" is enabled. This invention consists of: (1) a connector for insertion of a cord from an audio source, typically terminating to a stereo mini plug; (2) a circuit that detects connection of the cord and disables the radio function of the wireless headset and routes the corded audio input to the receivers; and, (3) a dual-purpose microphone that accepts voice input in standard communication mode and switches to noise measurement when a cord is connected for stereo listening, The primary advantage of this solution is to offer the end user a single device that works in both a corded and cordless mode.

Flight mode for wireless headsets

Abstract

This invention relates specifically to a stereo Bluetooth headset but potentially to any

wireless headset or headphones.

This invention involves mechanical, electrical and acoustical fields.

Currently, wireless headsets and headphones cannot be used in-flight due to FAA

regulations. Owners of wireless headsets and headphones are forced to carry corded

versions to use when traveling by air.

This invention involves the integration of a connector and electrical circuit into a

wireless headset (or headphones) that allows the user to plug a cord into the headset,

which is connected to an audio source, automatically disabling the wireless capabilities

of the headset.  By disabling wireless functions and providing for corded audio input, a

device can be used in passenger aircraft. This feature is referred to as "flight mode."

When implemented in a stereo wireless headset, an additional feature called “dual

purpose mic" is proposed with this invention. In addition to disabling the wireless

capabilities when a cord is connected to a stereo wireless headset, the headset

microphone automatically switches from communication mode (assumed to capture

voice) to noise-cancellation mode where it measures background noise for cancellation

in the receive paths to provide an improved listening experience in noisy environments.
