Description

This creation is to provide a micro piezoelectric sensing device, especially a micro piezoelectric sensing device that can enhance the signal transmission of the micro piezoelectric sensor and improve the accuracy of signal transmission.

In a general micro piezoelectric sensor device, the micro piezoelectric sensor is usually arranged between an upper shell and a lower shell, and the upper shell and the lower shell are combined with each other in a screw, tenon or tight fitting manner; The upper shell or the lower shell drives the micro piezoelectric sensor through the limited micro-deformation of the upper shell or the lower shell, which is used for various signal transmission.

However, as far as the current structural design is concerned, the upper shell and the lower shell are combined with each other by screws, tenons or tight fitting, although the upper shell and the lower shell can be tightly combined to achieve the reliability of the shell locking. However, this method will leave no more surplus space between the upper shell and the lower shell, leading to insufficient deformation of the upper or lower shell, and unable to drive the micro piezoelectric sensor, resulting in vibration signal sensing of the micro piezoelectric sensor The ability to reduce and attenuate.
