Patent ID: 7548625

Claim:
A method of testing audio performance, the method comprising: providing a two-way mobile voice-enabled communications device, the device comprising a microprocessor, a microphone connected to the microprocessor, a speaker connected to the microprocessor, an auxiliary input/output device connected to the microprocessor, a memory connected to the microprocessor, and a software module stored in the memory which configures the microprocessor to route signals from the microphone to the auxiliary input/output device; producing a microphone electric audio test signal on an audio generator external to the two-way mobile voice-enabled communications device; providing the microphone electric audio test signal of the audio generator as input to an external speaker; outputting a microphone acoustic audio test signal from the external speaker corresponding to the microphone electric audio test signal; receiving the microphone acoustic audio test signal output from the external speaker as an input to the microphone of the two-way mobile voice-enabled communications device; outputting a microphone electric audio output signal from the microphone of the two-way mobile voice-enabled communications device corresponding to the microphone acoustic audio test signal; directly routing the microphone electric audio output signal from the microphone to the auxiliary input/output device using the microprocessor; outputting the microphone electric audio output signal from the auxiliary input/output device to an external test system; and analyzing the microphone electric audio output signal output from the auxiliary input/output device on the external test system.
