OPTIMIZING AUDIO PROCESSING FUNCTIONS BY DYNAMICALLY COMPENSATING FOR VARIABLE DISTANCES BETWEEN SPEAKERS AND MICROPHONES IN AN ACCESSORY DEVICE

摘要

accessory device having a plurality of speakers and / or microphones are provided to perform a plurality of audio functions for use with the mobile device. Audio transducers (e. G., Microphone and / or speakers) may be housed in one or more expandable and / or rotatable in an adjustable arm. To compensate for the undesired feedback signal that is between the speaker and the microphone, to implement the acoustic echo canceller may determine the appropriate distance and relative position between the speaker and the microphone. Acoustic echo cancellation is to remove the echo from the voice communication, thereby improving the quality of the sound. The removal of unwanted signal that is captured by the microphone is characterizing the audio signal path to the microphone from the speakers, including the distance and the relative position between the speaker and microphone (the speaker-microphone distance path profile) by It may be achieved. Optimum distance and the relative position between the speaker and the microphone is provided to the user to optimize performance. ;
