ACTIVE NOISE REDUCTION MODULE OF ACOUSTOELECTRIC SENSOR AND SOUND MONITOR

WIPO Patent Application WO/2022/047905

A1

Disclosed are an active noise reduction module of an acoustoelectric sensor and a sound monitor. The active noise reduction module of the acoustoelectric sensor comprises an acoustoelectric sensor assembly used for picking up target sound, a plurality of external sound receiving devices provided outside the acoustoelectric sensor assembly and used for picking up external noise, at least one internal sound receiving device provided in the acoustoelectric sensor assembly and used for picking up sound transmitted into the acoustoelectric sensor assembly, and a noise reduction assembly at least partially provided in the acoustoelectric sensor assembly and used for reducing noise picked up by the acoustoelectric sensor assembly; the noise reduction assembly is respectively electrically connected to the external sound receiving devices and the internal sound receiving device. The sound monitor comprises a probe in which the active noise reduction module of the acoustoelectric sensor is mounted. According to the active noise reduction module of the acoustoelectric sensor and the sound monitor disclosed in the present invention, the effect of external noise on pickup of target sound is eliminated by means of an active noise reduction technology, so that monitoring quality of the target sound is improved.
