| titleOfInvention | Ultrasonic radiator and manufacturing method of radiating plate for the ultrasonic radiator |
| abstract | The ultrasonic radiator includes a transducer, a mechanical amplifier, and a radiating plate. The transducer is coupled with the piezoelectric element and converts the input electrical signal into a mechanical vibration signal of the piezoelectric element. The mechanical amplifier amplifies the vibration of the piezoelectric element. The radiating plate includes a metal plate and a plurality of convex parts positioned on the radiating surface of the metal plate, and radiates ultrasonic waves into the air by receiving the amplified vibration signal from the mechanical amplifying unit. The plurality of convex portions include a polymer material, have a thickness greater than that of the metal plate, and satisfy a Young's modulus and density condition such that an error rate between the natural frequency of the metal plate and the natural frequency of the radiating plate is 5% or less. |
