product description

The piezoelectric buzzer is made of lead zirconate titanate or lead niobium magnesium magnesium piezoelectric ceramic material. Silver electrodes are plated on both sides of the ceramic sheet, and after being polarized and aged, they are then bonded to a brass or stainless steel sheet. A piezoelectric ceramic piece is an electronic sounding element. A piezoelectric ceramic dielectric material is placed between two copper circular electrodes. When an AC audio signal is connected to the two electrodes, the piezoelectric piece occurs according to the frequency of the signal. Vibration produces a corresponding sound. Because of its simple structure and low cost, piezoelectric ceramics are widely used in electronic appliances such as toys, sounding electronic watches, electronic instruments, electronic clocks, timers and so on. Ultrasonic motors are made using related properties.
Classification of buzzer buzzer:
1. According to the principle of its driving mode, it can be divided into: active buzzer (including driving circuit, also called self-excited buzzer) and passive buzzer (external drive, also called other excited buzzer) Sounder); 2. According to the different construction methods, it can be divided into: electromagnetic buzzer and piezoelectric buzzer; 3. According to the different packages, it can be divided into: DIP BUZZER (Pin Buzzer) and SMD BUZZER (SMD Buzzer); 4. According to the difference of current, it can be divided into: DC buzzer and AC buzzer. Among them, DC is the most common piezoelectric buzzer, which uses piezoelectric material, that is, when the external force causes the piezoelectric material to occur Piezoelectric materials generate electrical charges during deformation. Similarly, piezoelectric materials deform when energized. The electromagnetic buzzer mainly uses the characteristics of the conductive conductor to generate a magnetic field, and uses a fixed permanent magnet and the conductive conductor to generate magnetic force to push the tympanic membrane fixed on the coil. Due to the different sounding principles of the two buzzers, the piezoelectric structure is simple and durable but has a single tone and color difference. It is suitable for devices such as alarms. The electromagnetic type is mostly used for voice, music and other equipment because of its good timbre.
