Abstract
Description
Technical Field
[0001] This utility model relates to the field of buzzer technology, and more specifically, to an active buzzer. Background Technology
[0002] A buzzer is an integrated electronic sounder powered by DC voltage. An active buzzer is an electronic sound-producing element with a built-in oscillation circuit that can produce sound independently when powered on. Compared to a passive buzzer (which requires an external drive signal), its structure and function are more independent, and it is widely used in alarm, prompt, and sound effect output scenarios.
[0003] Existing active buzzers are directly exposed to the elements, making them susceptible to damage when subjected to impact. To protect active buzzers, we have designed an active buzzer. Utility Model Content

[0018] like Figures 1 to 3 As shown, this utility model provides an active buzzer, including a lower housing 1, an active buzzer body 2 placed inside the lower housing 1, and a rubber pad 9 fixed to the inner wall of the lower housing 1. In the event of a collision, the rubber pad 9 can buffer and dampen the active buzzer body 2. A limiting mechanism is provided between the lower housing 1 and the active buzzer body 2 to limit the lower housing 1. The lower housing 1 has holes on both sides, and the pins on both sides of the bottom of the buzzer body 2 pass through the two holes and extend downwards. An upper housing 3 is placed on top of the lower housing 1. The lower housing 1 has anti-slip textures on both sides, and a side limiting mechanism is provided between the lower housing 3 and the lower housing 1. A heat dissipation mechanism is provided on top of the upper housing 3. The side limiting mechanism can limit the housing 3. The upper housing 3 and the lower housing 1 can protect the active buzzer body 2, and the heat dissipation mechanism can dissipate heat from the active buzzer 2.
[0019] The limiting mechanism includes an inner ring plate 11 and an annular rubber protrusion 13. The inner ring plate 11 is fixed to the outer wall of the active buzzer body 2. An annular limiting groove 12 is provided on the outer wall of the inner ring plate 11. The annular rubber protrusion 13 is fixed to the inner wall of the lower housing 1 and is inserted into the annular limiting groove 12. The lower housing 1 can be limited by the annular rubber protrusion 13 being inserted into the annular limiting groove 12. When the lower housing 1 needs to be disassembled, it is only necessary to pull the lower housing 1 to pull the annular rubber protrusion 13 out of the annular limiting groove 12.
[0020] The side limiting mechanism includes an outer ring plate 5 and an annular insert plate 15. The outer ring plate 5 is fixed to the upper outer wall of the lower housing 1.

[0021] The lower housing 1 has a label 4 affixed to its side wall, which allows information about the active buzzer body 2 inside the housing to be labeled.
[0022] The heat dissipation mechanism includes a heat dissipation vent 10 and a cooling fan 8. The heat dissipation vent 10 is located above the upper housing 3. The cooling fan 8 is fixed to the inner wall of the upper housing 3 directly below the heat dissipation vent 10.

The filter screen 7 prevents some impurities from entering the heat dissipation vent 10. By starting the cooling fan 8, the active buzzer 2 can be cooled.
[0023] The working principle and usage process of this utility model are as follows: The upper shell 3 and the lower shell 1 can protect the active buzzer body 2. When the active buzzer body 2 is involved in a collision, the rubber pad 9 in the lower shell 1 can buffer and dampen the active buzzer body 2, thereby preventing damage to the active buzzer body 2 during the collision. The heat dissipation mechanism can dissipate heat from the active buzzer body 2, thereby preventing the active buzzer body 2 from overheating and malfunctioning.
