Description

Technical Field

[0001] This utility model relates to the field of buzzer technology, specifically to an anti-vibration buzzer. Background Technology

[0002] A buzzer is an electronic component that functions as both a microphone and a speaker. It is often used as a sound source in devices such as alarm clocks, doorbells, and electronic toys. Its unique structure and working principle make it play an important role in various electronic devices.

[0003] According to a patent published on the China Patent Network, the patent title is "A Buzzer Device," patent application number 201921900778.2. This utility model relates to the field of fire-fighting equipment technology, specifically a buzzer device. It includes a buzzer body and a mounting base with a resonant cavity, as well as an elastic diaphragm. The buzzer body is adhered to one surface of the elastic diaphragm, and the edge of the elastic diaphragm is adhered to the mounting base. The area where the elastic diaphragm is adhered to the mounting base is completely offset from the area where the buzzer body is adhered. Compared to the rigid connection method in the prior art, the installation of the buzzer body and the mounting base in this utility model achieves a flexible connection effect, enabling high amplitude output to produce a loud sound, with low power consumption. The structure is simple and reasonable, facilitating mass production and potentially forming a general standard in the fire-fighting industry. However, the aforementioned buzzers have poor vibration resistance; when the buzzer itself vibrates, it may detach from its original position, causing the sound effect to gradually weaken.

[0004] Therefore, it is necessary to redesign and modify the buzzer to effectively prevent its poor vibration damping effect. Utility Model Content

[0014] As a preferred embodiment of this invention, both sides of the copper substrate are fixedly connected to a supporting short plate, which is used in conjunction with the copper substrate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model provides a certain anti-vibration function for the buzzer by setting an anti-vibration mechanism, which avoids the buzzer from shifting its position or even falling off due to vibration during long-term use, thus preventing the buzzer from reducing its sound output. It can effectively ensure that the buzzer can operate stably and continuously in the specified position.

[0017] 2. By incorporating a rubber damping strip, this invention provides an auxiliary function to the copper substrate, increasing its resistance and enabling it to operate more stably when encountering vibrations.
