Abstract:
A device for testing the operability of an audio speaker includes a housing, a unidirectional microphone and a display. The underside of the housing comprises a recessed area. The unidirectional microphone is positioned and oriented in the recessed area such that the unidirectional microphone is recessed from the underside of the housing. The display is positioned on the housing such that the display is visible when the testing device is placed proximate an audio speaker with the underside of the housing facing the audio speaker. The display may include at least one visual indicator operatively coupled to the unidirectional microphone such that, when the unidirectional microphone is receiving an acoustic signal, the at least one visual indicator is illuminated.
