Description
technical field [0001] This design relates to sensors, especially the field of a miniature piezoelectric acceleration sensor. Background technique [0002] Due to the complex internal structure of the current existing piezoelectric acceleration sensors, the traditional piezoelectric acceleration sensors have mass blocks inside. Due to the quality of the mass blocks, there are disadvantages such as large mass and large volume, which are very unsuitable for light sensor quality requirements. , Small-scale model tests and special tests with small volume requirements. Existing piezoelectric acceleration sensors with small size and light weight mainly rely on foreign imports, such as the KS94B series and KS95B series ultra-miniature piezoelectric acceleration sensors manufactured by MMF Company in Germany. Contents of the invention [0003] This design is a miniature piezoelectric acceleration sensor provided to solve the problems of large mass and large volume in the existing...
