Background

The buzzer is an electronic buzzer with an integrated structure, adopts direct current voltage for power supply, and is widely applied to electronic products such as computers, printers, copiers, alarms, electronic toys, automobile electronic equipment, telephones, timers and the like as a sounding device. The buzzer is mainly divided into two types, namely a piezoelectric buzzer and an electromagnetic buzzer. The piezoelectric buzzer mainly comprises a multivibrator, a piezoelectric buzzer, an impedance matcher, a resonator, a shell and the like. Some piezoelectric buzzer shells are also provided with light emitting diodes. Multivibrators are formed by transistors or integrated circuits. After the power supply is switched on (1.5-15V direct current working voltage), the multivibrator starts to vibrate and outputs 1.5-2.5 kHZ audio signals, and the impedance matcher pushes the piezoelectric buzzer to sound. The piezoelectric buzzer is made of lead zirconate titanate or lead magnesium niobate piezoelectric ceramic materials. Plating silver electrodes on both sides of the ceramic sheet, polarizing and aging, and adhering to brass sheet or stainless steel sheet. The electromagnetic buzzer comprises an oscillator, an electromagnetic coil, a magnet, a vibrating diaphragm, a shell and the like. After the power supply is switched on, the audio signal current generated by the oscillator passes through the electromagnetic coil, so that the electromagnetic coil generates a magnetic field. The vibrating diaphragm periodically vibrates to produce sound under the interaction of the electromagnetic coil and the magnet. The electric buzzer drives the metal sheet to vibrate and sound by the piezoelectric effect of the piezoelectric ceramics; the electromagnetic buzzer is driven by square waves by using an electromagnetic principle, the metal vibrating membrane is sucked down when the electromagnetic buzzer is powered on, and the metal vibrating membrane rebounds according to the elastic force of the vibrating membrane when the electromagnetic buzzer is not powered on, so that the piezoelectric buzzer is driven by the square waves, the electromagnetic buzzer is driven by 1/2 square waves, the piezoelectric buzzer needs higher voltage to have enough sound pressure, and the sound pressure is generally recommended to be more than 9V. Some specifications of piezoelectricity can reach more than 120dB, and larger size can easily reach 100 dB. Electromagnetic buzzer: the sound pressure of more than 85dB can be emitted by 1.5V, only the consumed current is greatly higher than that of a piezoelectric buzzer, and the response frequency of the electromagnetic buzzer can be lower when the size is the same; electromagnetic buzzers typically have sound pressures up to 90db mechanical buzzers are a small category of electromagnetic buzzers. The buzzer is composed of a vibration device and a resonance device, and the buzzer is divided into a passive separately excited type and an active self-excited type. The working sound production principle of the passive separately excited buzzer is as follows: the square wave signal is input into the resonance device and converted into a sound signal to be output. The working sound production principle of the active self-excitation buzzer is as follows: the DC power input is passed through the amplification sampling circuit of oscillation system and under the action of resonance device the sound signal can be produced.
