METHOD AND APPARATUS FOR ACOUSTICS TESTING OF A PERSONAL MOBILE DEVICE
First Claim
1. A system for audio testing a portable media device, comprising:
- a portable handheld test fixture having an acoustic port selected from the group consisting of a speaker port, a microphone port, and an earpiece port, wherein said port becomes acoustically coupled via the test fixture to a respective acoustic aperture of the media device, which is associated with a speaker, a microphone, or an earpiece of the device, once the device has been installed onto the test fixture; and
a sound test tool selected from the group consisting of a reference sound source and a sound pressure level, SPL, meter, the sound test tool having an input or output sound port that is to be removably coupled to said acoustic port of the test fixture.

Abstract
A portable handheld test fixture has an acoustic port, e.g. a speaker port, a microphone, and/or an earpiece/receiver port. Once the media device has been installed onto the test fixture, the port becomes acoustically coupled to a respective acoustic aperture of the media device that is associated with a speaker, a microphone, or an earpiece/receiver as the case may be. A sound test tool, e.g. a reference sound source and/or a sound pressure level, SPL, meter, has an input or output sound port that can be removably coupled to the acoustic port of the test fixture. Other embodiments are also described and claimed.

9. An apparatus comprising:
-
a portable media device having communications circuitry, a display, a speaker, and a microphone, wherein the media device implements a digital media player function that plays music through the speaker and/or video through the display, and wherein the media device is to a) emit a first audio test signal by the speaker and simultaneously show a spectral and/or sound level characteristic of the first audio test signal on the display, and b) measure a second audio test signal being detected by the microphone and simultaneously show a spectral and/or sound level characteristic of the measured signal on the display. - View Dependent Claims (10)

11. An apparatus comprising:
-
a cellular telephone handset having communications circuitry, a display, an earpiece, and a microphone, wherein the handset implements a wireless telephony function that allows a user to hear a telephone call through the earpiece, and wherein the handset is to a) emit an audio test signal by the earpiece and simultaneously show a spectral and/or sound level characteristic of the audio test signal on the display, and b) measure another audio test signal being detected by the microphone and simultaneously show a spectral and/or sound level characteristic of the measured signal on the display.
