First Claim
Patent Images
1. A method of operating an accessory, the method comprising:
- communicating, by the accessory to a mobile communication device, capabilities of the accessory, the capabilities including an option to provide an input audio signal to the mobile communication device through an audio input path concurrently with receiving an output audio signal from the mobile communication device through an audio output path;
in response to receiving a notification from the mobile communication device to enter duplex audio mode;
enabling the audio input path by the accessory;
receiving an input audio signal by the accessory from an input audio source; and
delivering the input audio signal on the audio input path by the accessory while concurrently receiving the output audio signal through the audio output path; and
in response to receiving a termination notification to exit duplex audio mode from the mobile communication device, disabling the audio input path by the accessory.

Abstract
Duplex audio is provided for a mobile communication device and an accessory. In some embodiments, the accessory can selectably operate in a duplex audio mode, concurrently sending audio to and receiving audio from the mobile communication device, or in another audio mode. In duplex audio mode, the accessory can enable its internal audio processing operations (e.g., echo cancellation) while the mobile communication device disables its corresponding internal operations or vice versa. The mobile communication device can control when the accessory transitions into and/or out of duplex audio mode.

14. An accessory for use with a mobile communication device, the accessory comprising:
-
a controller configured to communicate capability information for the accessory to the mobile communication device, the capability information indicating that the accessory is operable to provide an input audio signal to the mobile communication device through an audio input path concurrently with receiving an output audio signal from the mobile communication device through an audio output path; an input/output (I/O) interface configured to communicate with the mobile communication device, the I/O interface including the audio input path to send the input audio signal, the audio output path to receive the output audio signal, and a control signal path to communicate initiation and termination notifications for duplex audio mode between the accessory and the mobile communication device; and an audio processing section coupled to the I/O interface and configured to receive the output audio signal from the mobile communication device on the audio output path and to send the input audio signal to the mobile communication device on the audio input path, wherein the audio processing section is further configured to concurrently enable the audio input and audio output paths in response to receiving an initiation notification and to disable the audio input path in response to receiving a termination notification. - View Dependent Claims (15, 16, 17)
