Directional capability testing of audio devices
First Claim
1. A system, comprising:
- a controller configured to receive data from an audio device;
a first linear actuator that is responsive to the controller to move the audio device along a horizontal axis;
a rotary actuator that is responsive to the controller to rotate the audio device;
a sound source that is responsive to the controller to emit a test sound;
a second linear actuator that is responsive to the controller to move the sound source along a vertical axis that intersects the horizontal axis;
the controller being configured to perform actions comprising;
controlling the actuators to successively position the sound source and the audio device at multiple positions;
causing the sound source to emit the test sound at each of the positions; and
receiving data produced by the audio device in response to the test sound emitted at each of the positions.

Abstract
A test system for testing directional capabilities of an audio device includes a horizontal linear actuator and a vertical linear actuator. The horizontal linear actuator supports a rotary actuator upon which the audio device is placed. The vertical linear actuator supports a sound source. To test the device, the actuators are controlled to establish multiple relative positions of the audio device and the sound source. A test sound is emitted at each of the relative positions. The audio device is configured to provide data generated in response to the test sound at each of the relative positions. The test system receives and records the data along with coordinates indicating the relative positions to which the data corresponds.
