Detail
Piezoelectric transducer is an electronic audio component. The piezoelectric ceramic dielectric material is placed between two copper circular electrodes. When an AC audio signal is connected to two electrodes, the piezoelectric chip generates a frequency based on the size of the signal. Vibration occurs and corresponding sound is generated.
The working principle of a piezoelectric transducer: When a voltage is applied to a piezoelectric ceramic, it will undergo mechanical deformation with changes in voltage and frequency. On the other hand, when piezoelectric ceramics vibrate, they generate charges. Using this principle, when an electrical signal is applied to a vibrator composed of two piezoelectric transducers or piezoelectric ceramics and metal sheets (known as dual piezoelectric chip components), ultrasonic waves are emitted due to bending vibration. On the contrary, when ultrasonic vibration is applied to piezoelectric dual piezoelectric chip components, an electrical signal is generated. Based on the above effects, piezoelectric transducer can be used as an ultrasonic sensor.
Piezoelectric transducer
Piezoelectric transducer is an electronic audio component. The piezoelectric ceramic dielectric material is placed between two copper circular electrodes. When an AC audio signal is connected to two electrodes, the piezoelectric chip generates a frequency based on the size of the signal. When vibration occurs, a corresponding sound will be generated. Piezoelectric transducer is widely used in toys, voice Electric watch, electronic instruments, electronic clocks, timers and other electronic appliances because of its simple structure and low cost.
If a piezoelectric transducer is used to make a buzzer, there may be material mismatch or welding mismatch during the manufacturing process. Piezoelectric transducers are mostly calculated using capacitance, and capacitance is also calculated using the same method. The calculation adopts the calculation method of flat plate capacitance, so direct welding is required.
In transducers, the thickness or directional vibration and radial motion of piezoelectric energy transducers can be compared in many aspects, but from a professional perspective, the efficiency of thickness direction vibration will be higher, which means that if there are limitations, there may only be one radial vibration. Therefore, the vibration in the thickness direction of piezoelectric transducer components is very important. Special circumstances may not necessarily be the case.
