| titleOfInvention | A Microcomputer Piezoelectric Ultrasonic Transducer with V-shaped Spring |
| abstract | The utility model discloses a microcomputer piezoelectric electric ultrasonic transducer with a V-shaped spring. The transducer is provided with a base, a structural layer, a bottom electrode, a piezoelectric layer and an upper electrode. The working principle of the transducer is to use the forward and reverse piezoelectric effects to realize the conversion of mechanical energy to electrical energy or electrical energy to mechanical energy. The utility model is designed to connect two regions with opposite stress signs of the diaphragm through a V-shaped spring on the structural layer, and utilizes the multi-stage stiffness characteristics of the V-shaped spring to realize a large bandwidth. At the same time, the V-shaped spring is beneficial to reduce the initial deformation of the diaphragm under the action of residual stress, thereby improving the sensitivity of the transducer. |
