[0002] At present, fault alarms at home and abroad are mainly electromagnetic buzzers. Compared with electromagnetic buzzers, piezoelectric ceramic buzzers have the advantages of low power consumption, energy saving, good reliability, low cost, small size, light weight, thin thickness and strong anti-magnetic interference ability. In addition to these advantages, piezoelectric buzzers will not generate arcing or radio frequency noise, will not interfere with other lines, and the sound frequency is controllable, which can produce high and low pitch effects.

[0003] After searching, the application with patent publication number CN220290449U discloses a buzzer, including a shell, the top of the shell is a sound hole, the upper part of the outer wall of the shell is provided with an external thread, a locking ring is screwed on the external thread, and a diaphragm arranged in the shell divides the cavity of the shell into an upper cavity and a lower cavity, and the upper cavity is connected to the sound hole, and a circuit board loaded with sound elements is provided in the lower cavity, which is easy to install and use.

[0004] However, due to the high power and large size of the electromagnetic buzzer, it cannot achieve the effect of reducing power consumption and saving electricity and energy. At the same time, since the shell is in an integrated shape, the diaphragm needs to be manually installed on the inner wall of the shell, the structure is complicated, and fast and fully automatic processing cannot be achieved, resulting in low production efficiency.

[0005] Therefore, we proposed a new type of piezoelectric buzzer for fault alarm. Utility Model Content

In this way, the buzzer can be stably installed in the upper shell to ensure the stability of the buzzer.

[0012] Preferably, the rotating block is rotatably connected to the limiting groove, which can facilitate the rotation of the buzzer, thereby clamping the limiting block between the convex ring and the upper shell.

[0013] Preferably, a waterproof and sound-permeable membrane of matching specifications is adhered to the bottom surface of the sound outlet hole by adhesive, so as to prevent rainwater from the outside from entering the interior through the sound outlet hole, thereby improving its service life.
