    摘要: A mobile device includes at least one speaker and an audio subsystem for providing an audio signal to the at least one speaker for playback by the at least one speaker. The audio subsystem operates by detecting a distance to a user of the mobile device using a proximity sensor and controlling volume output of the at least one speaker based on the distance to the user of the mobile device and the operational status of the proximity sensor. If it is determined that the proximity sensor is functional, the audio subsystem applies a gain factor to the audio signal that varies based on the distance to the user or limits the maximum allowable speaker output based on the distance. A high or low gain setting may be applied for when the user is far away or in close proximity to the mobile device. If it is determined that the proximity sensor is non-functional, the audio subsystem applies a fixed gain factor to the audio signal independently of the distance to the user.

    摘要: An audio system including a first audio unit and a second audio unit coupled to the first audio unit through an audio bus. A first processor is coupled to the first audio unit. The first processor is configured to transmit bits comprising audio content to the second audio unit over the audio bus. The first processor is further configured to receive a control command selected from a plurality of control commands, and in response, interrupt the bits comprising audio content and send a preamble and a control message on the audio bus, wherein the control message corresponds to the control command. A second processor is coupled to the second audio unit. The second processor is configured to monitor the audio bus for a preamble, and if a preamble is detected, then process the control message and execute the corresponding control command.

    摘要: The present disclosure provides a method of determining microphone polarity in a headset. By being able to detect the polarity of the microphone within the headset, a portable electronic device may be compatible with any headset and is not limited to use with a specific headset. By applying a detection signal over one of lines within a headset cable, a return signal may be sensed on one of the other lines to determine which of the lines is the ground line and which line is the microphone line.
