    • The present invention includes apparatuses and methods comprising a means for detecting the presence of speakers and microphones coupled to a portable multi-function device (such as Apple's iPhone™). In response, a portable multi-function device can adapt its output depending on the nature of the coupled headset device. In particular, a portable multi-function device containing the present invention can, upon detecting only one speaker in a coupled headset accessory device, combine the multiple channels of a stereo audio signal into a single mono audio signal. Likewise, a portable multi-function device containing the present invention can alert users to the absence of a coupled microphone.
    • 本发明包括装置和方法,包括用于检测耦合到便携式多功能装置(例如Apple's iPhone TM)的扬声器和麦克风的存在的装置。 作为响应,便携式多功能设备可以根据耦合的耳机设备的性质来适应其输出。 特别地,包含本发明的便携式多功能设备可以在检测到耦合的耳机附件设备中仅一个扬声器时将立体声音频信号的多个通道组合成单个单声道音频信号。 同样,包含本发明的便携式多功能装置可以提醒用户不存在耦合麦克风。

    • 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).
    • 提供单个插脚,多信号导通插头和插头检测电路。 插头可以电耦合到包括麦克风的立体声耳机。 插头可以包括沿着插脚的长度以预定顺序布置的四个信号导通区域。 检测电路可以用于确定麦克风类型的插头(例如,包括麦克风区域和两个音频区域的四区域插头,或包括麦克风区域和仅一个音频区域的三区域插头)或非麦克风类型的 插头(例如,立体声插头)插入到电子设备(例如,移动电话)的插孔中。 检测电路还可以检测响应于耳机中包括的一个或多个开关的用户激活而执行的用户激活的功能。 例如,耳机可以包括用于执行关于麦克风的功能的单个开关(例如,终端呼叫功能)。

    • A mandrel assembly has a mandrel, a biasing member, and a outer member. The biasing member biasly maintains the outer member in a first position, which corresponds to a contoured portion of the mandrel, when the outer member is either on the access or the blind side of a workpiece. The biasing member is compressible to allow the outer member to move into a second position as the outer member is moved through an opening in the workpiece. In the first position, the outer member includes a maximum outer circumference that is larger than the opening of the structural workpiece. In the second position, the outer member includes a maximum outer circumference that fits within the opening of the structural workpiece.
    • 心轴组件具有心轴,偏置构件和外部构件。 当外部构件处于工件的进入或盲侧时,偏置构件偏置地将外部构件保持在第一位置,该第一位置对应于心轴的轮廓部分。 当外部构件移动通过工件中的开口时,偏置构件是可压缩的,以允许外部构件移动到第二位置。 在第一位置,外部构件包括大于结构工件的开口的最大外周。 在第二位置,外部构件包括装配在结构工件的开口内的最大外周。
