Abstract

The invention belongs to the technical field of buzzers, and discloses a buzzer with adjustable sound wave intensity. The positive and negative pins of the buzzer are welded and installed in the middle of the PCB circuit board. A coil is wound on the middle column of the iron sheet, and a magnet is welded on the iron sheet, and a copper ring is welded and fixed on the top of the magnet. The top of the copper ring is the first vibrating sheet, the first The vibrating plate and the third vibrating plate are fixedly installed on the protective shell through the vibrating plate adjusting rod, and pass through the other end of the protective shell. The buzzer with adjustable sound wave intensity is equipped with multiple vibrating pieces inside the buzzer. According to the different amplitudes generated when different vibrating pieces vibrate together, the intensity of different sound waves can be adjusted, so that the buzzer can be compared Compared with the traditional buzzer, the sound wave intensity can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of buzzers, in particular to a buzzer with adjustable sound wave intensity. 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. [0003] At present, the buzzer adjusts its tone according to the current, but the input current of the buzzer is fixed, so that the sound of the buzzer cannot be adjusted, and the sound intensity cannot be adjusted. A sonic intensity for vocalization. [0004] In summary, the problems in the prior art are: [0005] The magnitude of the input current of the buzzer is fixed, so that the sound of the buzzer cannot be adjusted. Content...
