    • This is directed to systems and methods for detecting the insertion of a plug in a device port without physically contacting the plug. For example, systems and methods are provided for detecting the insertion of an audio plug into an audio jack without using physical contacts placed in the periphery of the audio jack. In some embodiments, an electrically conductive element (e.g., a circuit board trace) can be provided on a surface of the port or within the port wall. When a metallic or conductive plug is inserted into the port, the plug can interact with the conductive element and cause a change in capacitance or induction detected by appropriate circuitry coupled to the conductive element. In some embodiments, an optical sensor can be used to detect a plug placed in a port. In some embodiments, the electronic device can detect distinguishable attributes associated with the contact between the electrical contact of plug and port contacts using an appropriate sensor (e.g., a microphone or an accelerometer).
    • 这涉及用于检测插头插入设备端口而不物理接触插头的系统和方法。 例如,提供了用于检测音频插头插入到音频插孔中而不使用放置在音频插孔周边的物理触点的系统和方法。 在一些实施例中,导电元件(例如,电路板迹线)可以设置在端口的表面或端口壁内。 当金属或导电插头插入端口时,插头可以与导电元件相互作用,并引起电容变化或通过耦合到导电元件的适当电路检测到的感应。 在一些实施例中,可以使用光学传感器来检测放置在端口中的插头。 在一些实施例中,电子设备可以使用适当的传感器(例如,麦克风或加速度计)来检测与插头和端口触点的电触点之间的接触相关联的可区分属性。
