内部通信装置头戴式耳机的连接与断开

Intercom headset connection and disconnection

Abstract

一种头戴式耳机,能够经由线缆耦合到内部通信系统,能够经由头戴式耳机的无线收发器无线地耦合到无线设备,以及能够经由另一线缆连接到有线设备。头戴式耳机的控制器单独地监视通过其头戴式耳机可以耦合到内部通信系统的麦克风导体和音频导体,以检测该头戴式耳机的通信麦克风和声学驱动器之一或者两者是否耦合到内部通信系统,并且监视无线收发器的操作状态,以检测无线收发器是活跃的、在待机中还是使用中;以及响应于通过该监视观测到的内容,而选择性地将系统接地导体耦合到一个麦克风导体,选择性地提供本地侧音,和/或选择性地提供本地麦克风偏置电压。
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.
