Abstract: Embodiments of the invention include methods, apparatus, systems and means for distinguishing between microphone line signals resulting from: actuation of a microphone button of a headset plugged into a telephone device jack, and removal of the headset plug form the jack. During a telephone call, a first signal can be detected on a microphone line of a headset jack to indicate whether a microphone button of the headset is actuated. Also, while the headset plug is being disconnected from the jack, a transition on the microphone line can be detected, from a second signal indicating that the microphone is being disconnected, to a third signal indicating that the microphone button is actuated. Consequently, to avoid erroneously hanging up a call, transitions to the third signal when removing the plug form the jack can be ignored and the call can be maintained. Other embodiments are also described and claimed.

Abstract translation: 本发明的实施例包括用于区分麦克风线路信号的方法，装置，系统和装置，所述麦克风线路信号是：插入到电话设备插孔中的头戴式耳机的麦克风按钮的致动以及从插座移除耳机插头。 在电话呼叫期间，可以在耳机插孔的麦克风线上检测第一信号，以指示耳机的麦克风按钮是否被致动。 此外，当耳机插头与插孔断开连接时，可以从指示麦克风被断开的第二信号检测到麦克风线上的转换到指示麦克风按钮被致动的第三信号。 因此，为了避免错误地挂断呼叫，可以忽略从插头拔出插头时转换到第三信号，并且可以保持呼叫。 还描述和要求保护其他实施例。
