Types of ultrasonic transducers

There are many types of ultrasonic transducers & according to the mechanism of energy conversion And the transducer materials used can be divided into piezoelectric transducers and magnetostrictive transducers Transducer, electrostatic transducer (capacitive transducer), electromagnetic acoustic transducer, Mechanical ultrasonic transducer, etc. & According to the vibration mode of the transducer, it can be divided Longitudinal (thickness) vibration transducer, shear vibration transducer, torsion Vibration transducers, bending vibration transducers, longitudinal 3 torsional compound and longitudinal 3 Bending compound vibration mode transducer etc. & According to the working medium of the transducer, Can be divided into gas-mediated ultrasound transducer, liquid transducer and solid transducer According to the working state of the transducer, it can be divided into emission type ultrasonic transducer Transducer, receiving ultrasonic transducer and transceiving dual-purpose ultrasonic transducer& According to the input power and working signal of the transducer, it can be divided into power super Acoustic transducers, detection ultrasonic transducers, pulse signal transducers, modulation Signal transducers and continuous wave signal transducers etc. & according to the transducer The shape can be divided into rod transducer, disc transducer, cylindrical transducer Transducers, spherical transducers and composite ultrasonic transducers, etc. In addition, no The same application requires different forms of ultrasonic transducers, such as plane wave ultrasound Acoustic transducers, spherical wave ultrasonic transducers, cylindrical wave ultrasonic transducers, Focused ultrasound transducer and array ultrasound transducer, etc.
