Mechanical buzzer:
Mechanical buzzer is a special subcategory of electromagnetic buzzer, which is composed of oscillator, electromagnetic coil, magnet, and housing. Unlike the ordinary electromagnetic buzzer, the vibration plate of the mechanical buzzer is inlaid on the housing, and his frequency is generally lower at about 0.5KHZ, while the frequency of the general electromagnetic buzzer is about 2KHZ. After the power supply is turned on (as small as 1.2VDC/1.5VDC/3.0VDC, as large as 110VAC,220VAC), the audio signal current generated by the oscillator passes through the electromagnetic coil, causing the electromagnetic coil to generate a magnetic field. Under the interaction of the electromagnetic coil and the magnet, the diaphragm on the housing is periodically knocked to make a sound.
Mechanical buzzer is mainly suitable for electrical products (egg boil, soybean milk machine, etc.) electronic products warning sound use; It is also used for the main components on the mouse repeller, because it not only emits a frequency of 0.5KHZ at the same time the whole buzzer has a vibration, which can be transmitted to the mouse through the underground, so as to achieve the role of repelling mice. Today's mechanical buzzers are generally active. Active mechanical buzzer contains audio oscillation circuit, connected to the DC power supply can send "da, da, da ----" sound at the same time there is an obvious vibration.
