What is ultrasonic transducer

Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies and convert electrical signals into mechanical vibrations by the piezoelectric effect of the material. When the transducer is used as a transmitter, the electrical oscillating signal sent from the excitation source will cause a change in the electric or magnetic field in the electrical energy storage element of the transducer, which changes the mechanical vibration system of the transducer through some effect. A driving force is generated to cause it to vibrate, thereby propelling the medium in contact with the mechanical vibration system of the transducer to vibrate and radiate sound waves into the medium.

ultrasonic transducer is an energy conversion device whose performance description and evaluation requires many parameters. The characteristics of the transducer include resonance frequency, frequency bandwidth, electromechanical coupling coefficient, electroacoustic efficiency, mechanical quality factor, impedance characteristics, frequency characteristics, Directivity, transmit and receive sensitivity, etc. Transducers for different applications have different performance parameters. For example, for an emissive transducer, the transducer is required to have large output power and high energy conversion efficiency; Receiver-type transducers require a wide frequency band and high sensitivity and resolution. Therefore, in the specific design process of the transducer, the relevant parameters of the transducer must be rationally designed according to the specific application.

In order to determine the operating state of the transducer, the state equation of the mechanical vibration system and the equation of state of the circuit must be obtained. The equation of state of the mechanical system of the transducer (referred to as the mechanical vibration equation) is when the transducer is in operation. Describe the relationship between the force of the mechanical vibration system and the vibration velocity, and the equation of state of the circuit system (referred to as the circuit state equation) describes the vibration characteristics of the circuit system. Since the mechanical system and the circuit system of the transducer are coupled to each other Therefore, the vibration of the mechanical system will affect the balance of the circuit, and the change of the circuit will also affect the vibration of the mechanical system. Therefore, we always use these equations to analyze and discuss the working characteristics of the transducer.
