Abstract

An anti-corrosion buzzer disclosed by the present invention comprises a pedestal, a set of pins is arranged at the bottom of the pedestal, and a buzzer main body is fixed on the surface of the top endof the pedestal. The two sides of the buzzer main body are respectively equipped with a set of fastening grooves, the fastening buckles installed at the bottom of a shell at the upper ends of the fastening grooves cooperate with the fastening grooves, and a shielding layer, a waterproof layer, an anti-corrosion layer and a fireproof plate are arranged in the shell orderly from the inside to outside. A circuit board is fixed at the central position of the bottom end in the buzzer main body, the coils are arranged at the two sides of the circuit board and are fixed on the surface of a magnet, and an oscillator is installed at the top position of the circuit board via a support. A vibrating diaphragm is arranged between the side walls in the buzzer main body above the oscillator, and a speaking terminal arranged at the top of the buzzer main body cooperates with the vibrating diaphragm. By arranging the speaking terminal, the shielding layer, the fireproof plate, the waterproof layer, the fastening buckles and the fastening grooves, the anti-corrosion buzzer of the present invention has the advantages of being convenient to install and disassemble, and being good in security measureseffect.

Description

technical field [0001] The invention belongs to the technical field of buzzers, in particular to an anti-corrosion buzzer. Background technique [0002] The buzzer is an electronic sounder with an integrated structure. It is powered by DC voltage and is widely used as a sounding device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, and timers. , The buzzer is mainly divided into two types: piezoelectric buzzer and electromagnetic buzzer. The buzzer is represented by the letter "H" or "HA" in the circuit (the old standard uses "FM", "ZZG", "LB", "JD", etc.), piezoelectric buzzer: piezoelectric buzzer The device is mainly composed of a multivibrator, a piezoelectric buzzer, an impedance matcher, a resonance box, and a shell. Some piezoelectric buzzers are also equipped with light-emitting diodes on the shell; electromagnetic buzzers: electromagnetic buzzers The buzzer is composed of an oscill...
