Sony patents robotic arm to move microphones for better sound tests

Patent drawing
Patent drawing from the official filing.

Sony describes a device that uses two motors to rotate a microphone in both vertical and horizontal directions. This setup allows the microphone to move freely in space, keeping it away from the physical structure that holds it.

Why it mattersThis tool could help engineers test how speakers and headphones sound from different angles without the stand itself blocking or reflecting the sound.

In the filing’s own words

To change the position and orientation of a microphone with a high degree of freedom and to suppress the influence of a structure on acoustic measurement. The measurement device is a measurement device for performing acoustic measurement, and includes one or more microphones configured to acquire sound output from a sound source at a sound receiving point; a first support which directly or indirectly supports the one or more microphones such that the sound receiving point is located at a rotation center or in the air at a predetermined distance from the rotation center; a second support which supports the first support at a lower end of the first support; a first motor configured to rotate the first support in a vertical direction; and a second motor configured to rotate the second support in a horizontal direction.

What exactly they claim (claim 1)

1. A measurement device for performing an acoustic measurement, comprising: one or more microphones configured to acquire sound output from a sound source at a sound receiving point; a first support which directly or indirectly supports the one or more microphones in such a manner that the sound receiving point is located at a rotation center or in the air at a predetermined distance from the rotation center; a second support which supports the first support at a lower end of the first support; a first motor configured to rotate the first support in a vertical direction; and a second motor configured to rotate the second support in a horizontal direction.
