Description

Technical Field

[0001] The utility model relates to the technical field of buzzers, in particular to a buzzer assembly with a waterproof structure. Background Art

[0002] A buzzer is an electronic sounder with an integrated structure. It is powered by a DC voltage and is widely used as a sound-generating device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers, etc. The working principle of a buzzer is based on an oscillation circuit. The oscillator generates periodic magnetic field changes, causing the components in the buzzer to vibrate and produce sound. The buzzer is mainly composed of a diaphragm, an oscillation source, and a drive circuit, and is used to issue alarms, reminders, or prompts. Buzzers are mainly divided into two types: piezoelectric buzzers and electromagnetic buzzers. The working principle of a piezoelectric buzzer is to use the piezoelectric effect to convert electrical energy into mechanical energy to produce sound. An electromagnetic buzzer generates magnetic force through an electromagnet to vibrate a metal sheet and produce sound.

[0003] The buzzer assembly usually refers to a complete unit consisting of the buzzer and its related components and accessories. It includes the buzzer itself and the possible drive circuit, connecting wires, fixing brackets, etc., so that it can be installed and used in a specific application environment.

[0004] The inventor discovered during the process of implementing the utility model:

[0005] When a common buzzer assembly is used outdoors, a waterproof structure needs to be set on the surface of the buzzer assembly to protect the buzzer assembly. However, the presence of the waterproof structure will hinder the propagation of sound, resulting in a reduction in the volume of the buzzer transmitted to the outside world. In view of this, the present application proposes a buzzer assembly with a waterproof structure. Summary of the invention
