Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a snap-fit ​​loudspeaker front cover mechanism. Background Technology

[0002] A loudspeaker is a device that converts electrical signals into sound, widely used in audio, communication, and transportation fields. Loudspeakers convert electrical energy into sound energy through vibrating components and are commonly found in car audio systems, mobile phones, and other devices. The loudspeaker front cover is the outer component of the loudspeaker assembly used to protect the internal structure and affect acoustic performance. However, the loudspeaker front cover mechanism cannot be securely fastened during use, making it difficult to install and remove easily. This leads to it easily falling off during use, reducing its stability and reliability. Furthermore, it cannot be multi-clamped, resulting in ineffective connections and reduced efficiency. Therefore, we propose a clamp-on loudspeaker front cover mechanism. Utility Model Content

[0003] To address the shortcomings of existing technologies, this application proposes a snap-fit ​​horn front cover mechanism that enables secure snap-fitting, facilitating easy installation and removal, and reducing the likelihood of detachment during use, thereby improving its stability and reliability.

[0004] This utility model provides the following technical solution: a snap-fit ​​horn front cover mechanism, including a front cover body, a movable ring being threaded onto the outside of the front cover body, a plurality of evenly distributed arc-shaped grooves being formed on the front cover body, a U-shaped snap-fit ​​plate being movably connected to the arc-shaped grooves through a rotating shaft and a bearing, and a flexible ring being fitted onto the outside of the front cover body.

[0005] As a preferred embodiment of this utility model, the left and right sides of the U-shaped snap-fit ​​plate are respectively hinged with connecting rods, and the top ends of the two connecting rods are hinged to the inner wall of the moving ring.

[0006] As a preferred embodiment of this utility model, a protective sheet is fitted inside the front cover, and the protective sheet has a plurality of evenly distributed sound-permeable holes.

[0007] As a preferred embodiment of this utility model, the movable ring has several evenly distributed through holes on its outer side, and a clamping post is inserted into each through hole.

[0008] As a preferred embodiment of this utility model, the rear end of the clamping post is attached to the flexible ring, and the U-shaped clamping plate and the clamping post are intermittently arranged.

[0009] The beneficial effects of this utility model are: this technical solution enables it to be securely fastened, thus making it easy to install and disassemble, and making it less likely to fall off during use, thereby improving its stability and reliability. It can also be fastened in multiple ways, thus enabling it to be effectively connected, improving its usage efficiency and work efficiency. Attached Figure Description

[0012] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0013] like Figures 1 to 4 As shown, a snap-fit ​​horn front cover mechanism includes: a front cover body 1, a movable ring 4 threadedly connected to the outside of the front cover body 1, a plurality of evenly distributed arc grooves 10 on the front cover body 1, a U-shaped snap-fit ​​plate 5 movably connected in the arc grooves 10 through a rotating shaft and a bearing, and a flexible ring 9 outer sleeve on the front cover body 1. In this embodiment, connecting rods 8 are hinged to the left and right sides of the U-shaped snap plate 5 respectively. The top ends of the two connecting rods 8 are hinged to the inner wall of the moving ring 4, so that it can be securely snapped in place, thereby making it easy to install and disassemble. This makes it less likely to fall off during use, thus improving its stability and reliability. Example

[0014] like Figures 1 to 4 As shown, a protective sheet 2 is fitted inside the front cover 1, and the protective sheet 2 has several evenly distributed sound-permeable holes 3. Implementation plan: The movable ring 4 has several evenly distributed through holes 7 on its outer side, and a clamping post 6 is inserted through the through hole 7. The rear end of the clamping post 6 is attached to the flexible ring 9. The U-shaped clamping plate 5 and the clamping post 6 are intermittently arranged, which allows for multiple clamping, thereby enabling effective connection and improving its usage efficiency and work efficiency.

[0015] Working principle: In use, the moving ring 4 first moves the U-shaped snap-fit ​​plate 5 through the connecting rod 8, allowing it to easily swing and snap onto the speaker housing. The snap-fit ​​post 6 is compressed, causing the flexible ring 9 to deform. Then, under the elastic force of the flexible ring 9, the snap-fit ​​post 6 snaps onto the speaker housing, enabling a stable snap-fit. This allows for easy installation and disassembly, making it less likely to fall off during use, improving its stability and reliability. It also allows for multiple snap-fits, enabling effective connection and improving its efficiency and work efficiency.

[0016] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
