⭐ Introduction of Buzzer
       Buzzer is a kind of articulating device that can transform audio signal into sound signal, which is commonly used in home appliances, electronic toys and game machines. Buzzer is mainly used for prompting or alarming, according to the appearance and use of different, can produce music, siren, alarm, sound bell and other different sounds. The buzzer used in washing machines emits a buzzer to prompt the user to operate the process.
        The buzzer used in gas appliances emits an alarm sound to warn the user that the gas appliance is burning. As a doorbell application of the buzzer is mostly issued by the "ding-dong" sound or music, prompting a guest to visit. The buzzer installed in the home alarm area mostly sends out an alarm sound. In factories, the application of buzzer, more electric bell, according to the different types of buzzer, its power supply is also different, some connected to DC, such as the car with an electric horn, some connected to AC, some need to be connected to a specific electronic circuit.
⭐ The Composition Of The Buzzer: buzzer by the wrong lead titanate or lead magnesium piezoelectric ceramic material. On both sides of the ceramic sheet plated with silver electrodes, after polarisation and aging treatment, and then with brass or stainless steel sheet glued together.
⭐ The Principle Of The Buzzer: the buzzer is the use of piezoelectric effect principle of work, when the alternating voltage is applied to it, it will produce mechanical vibration; Conversely, it will also produce voltage signals when mechanical force is applied to it. Therefore, the piezoelectric ceramic buzzer can be adapted as a vibration sensor. Piezoelectric ceramic buzzer by the mechanical force generated when the voltage signal is very weak, as a vibration sensor should be connected to the general use of voltage amplifiers.
