Abstract: A single prong, multiple signal conducting plug and plug detection circuitry is provided. The plug may be electrically coupled to a stereo headset including a microphone. The plug may include four signal conducting regions arranged in a predetermined order along the length of the prong. Detection circuitry may be operative to determine whether a microphone type of plug (e.g., a four region plug including a microphone region and two audio regions, or a three region plug including microphone region and only one audio region) or a non-microphone type of plug (e.g., stereo plug) is inserted into the jack of an electronic device (e.g., mobile phone). Detection circuitry may also detect user activated functions performed in response to user activation of one or more switches included with the headset. For example, the headset may include a single switch for performing a function with respect to a microphone (e.g., end-call function).

Abstract: Electronic devices and accessories such as headsets for electronic devices are provided. A microphone may be included in an accessory to capture sound for an associated electronic device. Buttons and other user interfaces may be included in the accessories. An accessory may have an audio plug that connects to a mating audio jack in an electronic device, thereby establishing a wired communications link between the accessory and the electronic device. The electronic device may include power supply circuitry for applying bias voltages to the accessory. The bias voltages may bias a microphone and may adjust settings in the accessory such as settings related to operating modes. User input information may be conveyed between the accessory and the electronic device using ultrasonic tone transmission. The electronic device may also gather input from the accessory using a voltage detector coupled to lines in the communications path.

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.
