Noise-reduction strong-sound electronic buzzer and control system thereof

Abstract

The invention discloses a noise-reduction strong-sound electronic buzzer which comprises a functional buckling disc, a clamping cover is inserted into the top of the functional buckling disc, a main shell is arranged at the bottom of the functional buckling disc, a main control core body is arranged in the main shell, and a bottom buckling disc is fixedly connected to the bottom of the main control core body. A plurality of silencing pipes are arranged at the top of the bottom buckling disc at equal intervals, the main shell is cylindrical, a plurality of cavity grooves capable of containing the silencing pipes are formed in the bottom of the main shell, transmission protruding columns are arranged at the top ends of the interiors of the cavity grooves, movable rods are arranged at the bottoms of the transmission protruding columns, and the outer ends of the movable rods are connected with metal sheets; and sound absorption cotton is attached to the inner wall of the silencing pipes. Aplurality of long-strip-shaped column rods are arranged at the bottom of the functional buckling disc at equal intervals, and a strip-shaped hole is formed in the middle of each column rod. The wholedevice can be rapidly assembled and disassembled, internal parts are convenient to replace and install, maintenance and repair are easy, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of buzzer equipment, in particular to a noise-reducing strong-pitch electronic buzzer and a control system thereof. 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. . Buzzers are mainly divided into two types: piezoelectric buzzers and electromagnetic buzzers. The packaging of the buzzer is an in-line piezoelectric buzzer, which is mainly composed of a multivibrator, a piezoelectric buzzer, an impedance matcher, and a resonance box. Light emitting diodes are also mounted on the piezo buzzer housing. Since the self-excited buzzer is driven by DC voltage, it does not need to be driven by an AC signal. It only needs to output the drive level to the drive ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a noise-reducing strong-pitched electronic buzzer and its control system, which solves the problem that most of the existing buzzers adopt a closed and integrated design during use, which is inconvenient to carry out Maintenance and repair, lack of noise reduction structure at the same time, the noise generated is too large, which affects the use effect, and the overall system is too single and the degree of intelligence is low
