Title:
PIEZOELECTRIC INDUCTION APPARATUS, USING METHOD THEREOF, AND INTELLIGENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/008132
Kind Code:
A1
Abstract:
The present application relates to the acoustoelectric field, and particularly relates to technologies responsible for collecting various sounds in mobile application scenarios, such as a hearing aid, a mobile phone and an intelligent loudspeaker. The present application describes a piezoelectric induction apparatus and a using method thereof. The piezoelectric induction apparatus has easily implemented process and high signal-to-noise ratio. In addition, the piezoelectric induction apparatus has high energy utilization rate and is not prone to air leakage during air conduction, thereby achieving a better sound pressure effect and generating a more stable output signal. The apparatus consists of a plurality of cantilevers, a piezoelectric induction unit and a base. The apparatus is mainly used to the acoustoelectric technical field, such as microphones, and can also be used in the field of audio devices and multimedia devices.
