Abstract

The invention belongs to the technical field of buzzers and discloses a buzzer with the adjustable sound wave intensity. Positive and negative pins of the buzzer are welded and installed in the middleof a PCB. An iron sheet is fixedly mounted above the PCB through welding. A coil and an iron sheet are wound on a middle stand column of the iron sheet. A magnet is installed on the iron sheet in a welded mode. A copper ring is fixedly installed above the magnet in a welded mode. A first vibrating reed is arranged above the copper ring. The first vibrating reed, a second vibrating reed and a third vibrating reed are fixedly installed on a protective shell through vibrating reed adjusting rods and penetrate out of the other end of the protective shell. According to the buzzer with the adjustable sound wave intensity, the plurality of vibrating reeds are arranged in the buzzer, and the intensity of generated different sound waves is adjusted according to different amplitudes generated whendifferent vibration sheets vibrate together. Therefore, the buzzer can adjust the sound wave intensity compared with a traditional buzzer.

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...
