Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically a dustproof and breathable mesh cover assembly for a loudspeaker unit. Background Technology

[0002] In fields such as audio equipment, public address systems, and smart terminals, the dustproof and breathable mesh cover of the speaker unit is a core component to ensure its stable operation and acoustic performance: on the one hand, it needs to block dust and foreign objects from entering, avoiding diaphragm wear and sound quality degradation; on the other hand, it needs to ensure smooth sound wave radiation and maintain transparent acoustic characteristics.

[0003] However, the design and installation methods of traditional dustproof and breathable mesh covers have significant drawbacks:

[0004] 1. Cumbersome disassembly and maintenance: The mainstream solutions use snap-fit, screw fastening, or glue bonding. Snap-fit ​​structures are prone to loosening under long-term vibration, leading to mesh displacement, dustproof failure, and even resonance noise; screw fastening requires tools, which is extremely inefficient in high-frequency maintenance scenarios such as stage sound systems and vehicle speakers; glue bonding cannot be repeatedly disassembled and reassembled, and replacement can easily damage the speaker surface, increasing maintenance costs.

[0005] 2. Insufficient stability: The elastic deformation of the clips and the loose gaps of the screws make it difficult to maintain the fit between the grille and the speaker body for a long time. Especially in outdoor and vehicle-mounted vibration environments, grille displacement will directly lead to abnormal sound wave diffraction and aggravate sound quality distortion.

[0006] Therefore, those skilled in the art have provided a dustproof and breathable mesh cover assembly for a speaker unit to solve the problems mentioned in the background art. Utility Model Content

[0007] The purpose of this invention is to provide a dustproof and breathable mesh cover assembly for a loudspeaker unit to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A speaker unit dustproof and breathable mesh cover assembly includes a speaker body, a lifting plate, semi-ring clamping members, and a mesh frame. Two semi-ring clamping members are arranged at the front of the speaker, forming a complete ring when joined. A mesh frame is positioned between the semi-ring clamping members, and a dustproof and breathable mesh is installed on the mesh frame, which is fixedly connected to the frame. Two spring grooves are formed on the outer wall of the front of the speaker body, each containing a spring rod. The left and right ends of the spring rods are fixedly connected to the inner walls of the left and right sides of the spring grooves. Spring blocks are fixedly connected to the rear ends of the semi-ring clamping members, each spring block being engaged within a spring groove and slidably connected to a spring rod.

[0010] As a further embodiment of this utility model: a semi-circular groove is provided on one side of each of the semi-circular clamping members, wherein the mesh frame is fitted into the semi-circular groove, and a movable block is provided on the rear side of the lower end of each of the semi-circular clamping members, wherein the movable block is fixedly connected to the semi-circular clamping member, and a slot is provided on the upper end of each of the semi-circular clamping members, wherein a movable groove is provided below the spring groove, wherein the movable groove is opened on the speaker body, and the movable block is fitted into the movable groove.

[0011] As a further embodiment of this utility model: a first guide rail and a second guide rail are provided above the spring groove, wherein the first guide rail and the second guide rail are both fixedly connected to the speaker body, a first sliding groove is provided on one side of the first guide rail, and a second sliding groove is provided on one side of the second guide rail.

[0012] As a further embodiment of this utility model: a sliding rod is provided in the first sliding groove, wherein the upper and lower ends of the sliding rod are fixedly connected to the inner walls of the upper and lower sides of the first sliding groove; a threaded rod is provided in the second sliding groove, wherein the threaded rod is rotatably connected to the second guide rail; a rotating disk is provided on the outer wall of the upper end of the threaded rod, wherein the rotating disk is fixedly connected to the threaded rod.

[0013] As a further embodiment of this utility model: a lifting plate is provided between the first guide rail and the second guide rail, wherein the left and right ends of the lifting plate are respectively engaged in the first slide groove and the second slide groove, and the lower end of the lifting plate is provided with two left and right insert rods, wherein the insert rods are fixedly connected to the lifting plate and inserted into the slots.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Tool-free quick disassembly, significantly improving maintenance efficiency: The rotating disc drives the threaded rod to lift the plate, allowing the insert rod to insert / disengage from the slot of the semi-ring clamp, completing the locking state switch; in conjunction with the elastic extension and retraction of the spring rod, the semi-ring clamp can quickly slide left and right to open / close. The entire process is manual and requires no tools, solving the cleaning and replacement problems of traditional mesh covers that are "tool-dependent and have cumbersome processes".

[0016] 2. Double fixing, vibration resistance and stability ensure performance: The semi-ring clamping component is engaged with the mesh frame through the semi-ring groove, ensuring that the mesh frame fits tightly with the speaker body; in addition, the lifting plate inserts the rod into the slot to lock the semi-ring clamping component axially, and with the continuous elastic force of the spring rod, the double constraint prevents vibration and loosening, ensuring the stable acoustic performance of the speaker.
