Abstract: A user device determines whether a device connected to its headset jack is an audio accessory device. If the device connected to the headset jack is an audio accessory, the user device connects one or more pins of the headset jack to an audio codec. If the device plugged into the headset jack is not an audio accessory device, the user device connects one or more pins of the headset jack to alternate circuitry. The user device then determines, through the alternate circuitry, an electrical operating parameter requirement of the accessory device, and provides, from the alternate circuitry, the required operating parameter to the accessory device through the headset jack. The alternate circuitry may include an adjustable voltage regulator and/or an adjustable current regulator and the required operating parameter may be one or more of a voltage supply and a current supply.

Abstract translation: 用户设备确定连接到其耳机插孔的设备是否是音频附件设备。 如果连接到耳机插孔的设备是音频附件，则用户设备将耳机插孔的一个或多个引脚连接到音频编解码器。 如果插入耳机插孔的设备不是音频附件设备，则用户设备将耳机插孔的一个或多个引脚连接到备用电路。 用户设备然后通过备用电路确定附件设备的电操作参数要求，并通过耳机插孔从备用电路提供所需的操作参数到附件设备。 替代电路可以包括可调电压调节器和/或可调电流调节器，并且所需的操作参数可以是电压源和电流源中的一个或多个。
