Abstract

A system and method of testing the audio performance of an acoustic device is provided. To test a device microphone, an audio signal is generated, provided to an external speaker, outputted to the device microphone, and routed to an auxiliary input/output device where it is outputted and analyzed. To test a device speaker, an audio signal is generated, inputted to an auxiliary input/output device, routed to the device speaker, outputted to an external microphone, and outputted to an audio analyzer.

Claims (13)

1, A method of testing the audio performance of an acoustic device (25,500), the acoustic device comprising a microprocessor (538), and a device microphone (10, 536), a speaker (534) and an auxiliary output device (15, 528) each coupled to the microprocessor, the method comprising steps of:
(a) producing an electric audio signal;
(b) providing the electric audio signal as an input to an external speaker (20) and outputting an acoustic audio signal representation thereof;
(c) providing the acoustic audio signal outputted from the external speaker (20) as an input to the device microphone (10, 536) and outputting a further electric audio signal representation thereof;
(d) causing the microprocessor (538) to route the further electric audio signal from the device microphone (10, 536) to the auxiliary output device (15, 528) and outputting it therefrom; and (e) analyzing the further electric audio signal outputted from the auxiliary output device (15, 528).
2. The method of claim 1 wherein the auxiliary output device (15, 528) is an electrical connector, step (d) including outputting the further electrical signal through the electrical connector.
3. The method of claim 1 or claim 2 including connecting the external speaker (20) to the device microphone (10, 536) with a seal prior to step (c).
4. The method of claim 2 or 3 wherein the electrical connector is a headset plug through which the further electric audio signal is outputted in step (d)
5. The method of claim 2 or 3 wherein the electrical connector is a serial port through which the further electric audio signal is outputted in step (d).
6. The method of any one of claims 1 -5 Wherein in step (a) the electric audio signal is produced externally to the acoustic device (25, 500) and in step (e) the further electric audio signal is analyzed externally to the acoustic device.
7. The method of any one of claims 1-7 wherein the acoustic device is a hand-held voice-enabled wireless communications device having an RF transceiver (511) coupled to the microprocessor.
8. The method of claim 7 wherein the acoustic device is enabled for two-way wireless data communications.
9. The method of any one of claims 1 -8 wherein the auxiliary output device (15, 528) is an auxiliary input/output device that is coupled to provide electric signals to the device speaker (50,534), the method comprising further steps of:
(f) producing a speaker test electric audio signal;
(g) receiving the speaker test electric audit signal at the auxiliary input/output device (15, 528);
(h) causing the microprocessor (538) to route the speaker test electric audio signal from the auxiliary input/output device (15, 528) to the device speaker (50, 534) and outputting therefrom a device speaker acoustic audio signal representation of the speaker test electric audio signal;
(i) providing the device speaker acoustic audio signal outputted from the device speaker as an input to an external microphone (55) and outputting a device speaker electric audio signal representation thereof; and (j) analyzing the device speaker electric audio signal outputted from the external microphone.
10. A method of testing the audio performance of an acoustic device (25, 500), wherein the acoustic device comprises a microphone (536), a device speaker (50, 534) and an auxiliary input device (15, 528) coupled to a microprocessor (538), the method comprising steps of:
(a) producing a speaker test electric audio signal;
(b) providing the speaker test electric audio signal as an input to the auxiliary input device (15, 528);
(c) causing the microprocessor (538) to route the speaker test electric audio signal from the auxiliary input device (15, 528) to the device speaker (50, 534); , (d) outputting from.the device speaker (50, 534)a device speaker acoustic audio signal representation of the speaker test electric audio signal;
(e) providing the device speaker acoustic audio signal outputted from the device speaker as an input to an external microphone (55) and outputting a device speaker electric audio signal representation thereof; and (f) analyzing the device speaker electric audio signal outputted from the external microphone.
11. The method of claim 10 wherein the auxiliary input device is an electrical connector to which the speaker test electrical audio signal is provided in step (b).
12. The method of claim 11 wherein the electrical connector is a headset plug to which the speaker test electrical audio signal is provided in step (b).
13. The method of claim 14 wherein the electrical connector is a serial port to which the speaker test electrical audio signal is provided in step (b).
