Abstract

The invention discloses a buzzer structure with composite audio for easy installation, which includes a shell, a piezoelectric buzzer and a resonance chamber. A piezoelectric buzzer is installed inside the shell, and the top of the piezoelectric buzzer is A resonance chamber is provided, and an outer ring is installed at the bottom of the shell. The structure of the present invention is scientific and reasonable, and it is safe and convenient to use. The outer ring is provided, and through the functions of chute, groove, slider and fixed block, it is convenient to According to the situation, slide the slider, adjust the position of the fixed block, and cooperate with the function of the connecting screw and the lock nut to fix its position, so that the buzzer can be better installed and fixed. Through the function of the movable shaft, it is convenient to adjust according to the actual needs. The fixed block is folded and hidden, which is easy to operate and easy to install. Through the function of the through hole, the inner ring and the receiving hole, the receiving hole on the side of the inner ring is overlapped with the through hole by squeezing the bump, so that the air at the bottom of the buzzer Circulation, improve the heat dissipation effect of the buzzer.

Description

technical field

[0001] The invention relates to the field of buzzer technology, in particular to a buzzer structure with composite audio for easy installation. 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. , where the composite audio buzzer includes a piezoelectric buzzer, the piezoelectric buzzer is mainly composed of a multivibrator, a piezoelectric buzzer, an impedance matcher, a resonance box, and a shell. The sound of the buzzer produces composite audio. The existing buzzer has a simple structure, and the shell is fixed as a whole. When the mounting hole of the fixed plane is incompatible with the fixing block of the buzzer due to errors, it is difficult to install the buzzer, and Excessively long connecting wire...
