Embodiment Construction

[0022] What is disclosed and claimed herein is intended to be applicable to earphones that are configured to be worn by a user in a manner in which at least one acoustic driver is located near the ear and where a microphone is located near the user's mouth to enable two-way audio communication. devices on or around your head. It should be noted that although specific embodiments of earphones incorporating a pair of acoustic drivers (one for each ear of the user) are presented with a certain level of detail, such presentation of specific embodiments is intended to facilitate understanding by way of example, and It should not be read as limiting the scope of the disclosure or what the claims cover.

[0023] It is intended that what is disclosed and claimed herein applies to headphones that also provide active noise reduction (ANR), passive noise reduction (PNR), or a combination of both. It is intended that what is disclosed and claimed herein applies to a headset configured to...

Abstract

A headset is able to be coupled via a cable to an intercom system, is able to be wirelessly coupled to a wireless device via a wireless transceiver of the headset, and is able to be connected to a wired device via another cable. A controller of the headset separately monitors the microphone conductors and audio conductors by which the headset may be coupled to the intercom system to detect whether or not one or both of a communications microphone and an acoustic driver of the headset are coupled to the intercom system, and monitors the operating state of the wireless transceiver to detect whether or not the wireless transceiver is inactive, on standby or in use; ; and selectively couples a system ground conductor to one of the microphone conductors, selectively provides a local sidetone, and/or selectively provides a local microphone bias voltage in response to what is observed through such monitoring.

Description

technical field [0001] The present disclosure relates to monitoring the connection between a headset and an intercom system or radio, possible responses to the status of the intercom or radio to which it is connected, and conserving headset power. Background technique [0002] Two-way communication headsets are often used in many types of vehicles, and in the case of various large machines, especially vehicles and machines that create a high noise environment during operation, making it possible to communicate with the driver, operator Necessary two-way communications for the crew or pilot would be impaired. Examples of such noisy environments include airports, cabs in commercial trucks and tractors, operator compartments in cranes and tunnel excavators, and crew compartments in tanks or other military vehicles. It is common for such vehicles or machines to incorporate an intercom system that provides one or more connection points to which such headsets are coupled. Such i...
