Microphone for detecting moving sound sources includes waveguide and camera with circular field of view for tracking moving source

摘要

The sound receiver includes a microphone (5) for receiving ambient sounds. A camera (6) with a circular field of view may be operated by a switch (7) may be used to follow the source of sound dynamically. A laser device (8) generates an envelope which encloses a waveguide (9) in order to protect the sound wave to which the microphone responds. The sound receiver includes a box (1) with an operating switch (2) and power source (3). An electronic chip (4) controls the device which includes a microphone (5) for receiving ambient sounds or a loudspeaker for producing sound. A camera (6) with a circular field of view may be operated by a switch (7) may be used to follow the source of sound dynamically. A further component comprises a laser device (8) which generates an envelope which encloses a waveguide (9) in order to protect the sound wave to which the microphone responds. The sound waves are thus protected against perturbations arising from the ambient environment.
