Abstract
Description
Technical Field
[0001] This utility model relates to the field of buzzer technology, specifically a buzzer component. Background Technology
[0002] A buzzer is an electronic component that converts electrical signals into sound using the piezoelectric effect. It is widely used in alarms, electronic device alerts, toys, and other fields. It consists of a piezoelectric ceramic plate and a metal vibrating plate, and features small size, low power consumption, and long lifespan.
[0003] According to a patent published on the China Patent Network, the patent title is "A Buzzer Structure," patent application number 202222297936.8. It includes a metal substrate, a piezoelectric ceramic sheet bonded to the inside of a circular groove using high-temperature adhesive, and an anti-detachment component inside the circular groove. This component includes four support pillars and several anti-slip protrusions. The four support pillars are evenly and fixedly installed at the bottom of the inner wall of the circular groove. This invention effectively strengthens the bond between the metal substrate, the piezoelectric ceramic sheet, and the high-temperature adhesive, effectively reducing the possibility of detachment and allowing the buzzer structure to continue operating normally, thus improving the alarm effect. However, in the aforementioned buzzer assembly, the ceramic sheet and electrode parts are constantly exposed, making them susceptible to accidental contact with external components, which could compromise their lifespan.
[0004] Therefore, the design of the buzzer assembly needs to be modified to effectively prevent the ceramic plate and electrode parts from being accidentally touched by external components. Utility Model Content

[0030] Electrode sheet assembly 2 is conductively attached;
[0031] A conductive silver layer 3 is applied to the surface of the electrode assembly 2;
[0032] A piezoelectric ceramic sheet 4 is attached to the top of the conductive silver layer 3;
[0033] The piezoelectric ceramic sheet 4 is provided with a shielding and protection mechanism 5 on its top. The shielding and protection mechanism 5 includes a circular cover plate 6. A through frame 7 is fixedly connected to both the front and back of the circular cover plate 6. An insert plate 8 is fixedly connected to both the front and back of the top of the metal substrate 1. The top of the insert plate 8 extends through to the top of the through frame 7. A rotating ring 9 is movably connected to the top of the circular cover plate 6 through a rotating shaft. An extension rod 10 is fixedly connected to both the front and back of the rotating ring 9. A locking block 11 is fixedly connected to the inner side of the extension rod 10. The inner side of the locking block 11 extends through to the interior of the insert plate 8. L-shaped positioning plates 12 are provided through both sides of the rotating ring 9. The side of the L-shaped positioning plate 12 away from the rotating ring 9 is slidably connected to the circular cover plate 6.
[0034] refer to Figure 1 and Figure 2 The front and rear sides of the top of the rotating ring 9 are fixedly connected to a convenient rotating mechanism 13. The convenient rotating mechanism 13 includes a vertical rod 14. The top of the vertical rod 14 is fixedly connected to a connecting plate 15. The front and rear sides of the top of the connecting plate 15 are fixedly connected to a push rod 16.
[0035] As a technical optimization of this utility model, the convenient rotating mechanism 13 makes it easier for users to rotate the rotating ring 9, thus increasing the convenience of rotation.
[0036] refer to Figure 2 Pull rings 17 are fixedly connected to the front and rear sides of the top of the L-shaped positioning plate 12. The pull rings 17 are used in conjunction with the L-shaped positioning plate 12.
[0037] As a technical optimization of this utility model, the pull ring 17 makes it easier for users to pull the L-shaped positioning plate 12, thus increasing user convenience.
[0038] refer to Figure 2 The top of the circular cover plate 6 has grooves 18 on both sides, and the L-shaped positioning plate 12 is slidably connected to the inside of the grooves 18 on the side away from the rotating ring 9.
[0039] As a technical optimization of this utility model, the groove 18 enables the L-shaped positioning plate 12 to slide more smoothly inside the circular cover plate 6, reducing the friction between the L-shaped positioning plate 12 and the circular cover plate 6, extending the service life of the L-shaped positioning plate 12, and at the same time limiting the L-shaped positioning plate 12.
[0040] refer to Figure 2Positioning grooves 19 are provided on both sides of the rotating ring 9, and the inner side of the L-shaped positioning plate 12 is engaged with the inside of the positioning groove 19.

[0042] refer to Figure 2 Both sides of the transparent frame 7 are fixedly connected with inclined plates 20, and the inner side of the inclined plates 20 is fixedly connected with the circular cover plate 6.
[0043] As a technical optimization of this utility model, by setting the inclined plate 20, the through frame 7 can be more firmly connected to the circular cover plate 6, which increases the tightness between the two and avoids the phenomenon of separation between the through frame 7 and the circular cover plate 6, thus ensuring the service life of the through frame 7 and the circular cover plate 6.
[0044] The working principle and usage process of this utility model are as follows: First, the user places the circular cover plate 6 on the top of the metal substrate 1, so that the electrode assembly 2, the conductive silver layer 3, and the piezoelectric ceramic sheet 4 are all inside the circular cover plate 6. Then, the insert plate 8 passes through the top of the through frame 7. Then, the user rotates the push rod 16, which drives the connecting plate 15 to rotate. The connecting plate 15 drives the upright rod 14 to rotate. The upright rod 14 drives the rotating ring 9 to rotate. The rotating ring 9 drives the extension rod 10 to rotate. The extension rod 10 drives the locking block 11 to move inward, so that the locking block 11 is engaged inside the insert plate 8. Then, the user moves the L-shaped positioning plate 12 inward through the pull ring 17, so that the L-shaped positioning plate 12 is engaged inside the positioning groove 19, thereby achieving the effect of shielding and protecting it.
[0045] In summary, this buzzer component changes the traditional situation where the ceramic plate and electrode parts are always exposed and easily touched. By using a circular cover plate 6 for shielding and protection, it will not be accidentally touched by external components, and its service life will not be compromised.
