Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a clip-on dust cover for audio. Background Art

[0002] The loudspeaker, also known as the "audio horn", is a very commonly used electroacoustic transducer device. It can be found in all sound-generating electronic and electrical equipment. In the development of the automobile era, the audio horn is an important component installed in the car. In order to avoid damage to the service life of the electronic components in the horn caused by dust in the horn, it is particularly important to use a dust cover for the car audio horn.

[0003] In order to prevent external dust from damaging the service life of the electronic components in the speaker, the dust cover may become clogged after long-term use, thereby affecting the sound effect. The dust cover in the prior art is mostly fixed by screws. When removing the dust cover, the screws need to be turned one by one, which results in low work efficiency and inconvenience in use. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that most dust covers are fixed by screws, and when the dust covers are disassembled, the screws need to be twisted one by one to disassemble, which results in low work efficiency and inconvenience in use, and to propose a sound clip-on dust cover.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sound card-type dust cover comprises a sound body and also comprises:

[0007] A dust cover, wherein an annular groove is provided in the speaker body, a positioning ring is rotated in the annular groove, and the dust cover is arranged in the positioning ring for dust prevention;

[0008] At least four groups of clamping assemblies, the four groups of clamping assemblies are evenly arranged between the dust cover and the positioning ring for fixing the dust cover in the dust cover;

[0009] A rotating extrusion assembly, which is arranged between the speaker body and the positioning ring and is used to quickly remove the dust cover;

[0010] And a positioning component used in conjunction with the clamping component, wherein the positioning component is arranged between the dust cover and the positioning ring and is used to align the dust cover and the positioning ring.

[0011] In a possible design, the positioning assembly includes four positioning grooves opened on the surface of the dust cover, and four positioning blocks are fixed to the inner wall of the positioning ring, and the four positioning blocks slide in the four positioning grooves respectively.

[0012] In a possible design, each group of the snap-fit ​​components includes a first groove opened on the surface of the dust cover, an elastic rod is fixed in the first groove, an elastic clamping block is fixed to the side end of the elastic rod, a snap-fit ​​groove is opened in the positioning ring, and the elastic clamping block and the snap-fit ​​groove are snap-fitted to each other.

[0013] In a possible design, the rotary extrusion assembly includes a fixed ring fixed in an annular groove, four arc-shaped extrusion plates are fixed in the fixed ring, the cross-section of the positioning ring is U-shaped, an accommodating gap is formed between the positioning ring and the annular groove, the fixed ring and the four arc-shaped extrusion plates are all arranged in the accommodating gap, and the four elastic blocks are respectively in arc-shaped extrusion contact with the four arc-shaped extrusion plates.

[0014] In a possible design, arc-shaped semicircular blocks are fixed to the side ends of the four elastic clamping blocks.

[0015] In a possible design, a semicircular groove connected to the annular groove is opened in the speaker body, a fixing plate is fixed on the surface of the positioning ring, the fixing plate is arranged in the semicircular groove, a tension spring is fixed to the side wall of the semicircular groove, the other end of the tension spring is fixed to the fixing plate, and a limit block for limiting the fixing plate is fixed in the semicircular groove.

[0016] In a possible design, a twist ring is fixed to a side end of the dust cover.

[0017] In the present application, when the dust cover needs to be installed, the positioning block is aligned with the positioning groove and the dust cover is inserted into the positioning ring. The inner wall of the positioning ring squeezes the elastic clamping block and the elastic rod to completely enter the first groove. After the dust cover is completely entered into the positioning ring, the elastic clamping block is clamped into the clamping groove, thereby fixing the position of the dust cover, and the dust cover can be fixed;

[0018] When the dust cover needs to be removed, the dust cover and the positioning ring are driven to rotate synchronously by twisting the twisting ring. The rotation of the positioning ring drives the clamped elastic block to perform circular motion. The side end of the elastic block contacts the arc of the arc extrusion plate during the circular motion. The arc surface of the arc extrusion plate squeezes the elastic block back into the first groove. At this time, the arc semicircular block at the side end of the elastic block faces the side wall of the clamping groove, and the elastic block slides along the inner wall of the clamping groove. The dust cover can be taken out by pulling outward. After the dust cover is taken out, the positioning ring is released from the limit, and the elasticity of the tension spring pulls the fixing plate to reset. The fixing plate drives the positioning ring to rotate and reset, so that the positioning ring recovers its position.

[0019] Beneficial Effects

[0020] In the utility model, the audio clip-on dust cover can achieve the effect of quickly fixing the dust cover in the positioning ring through the clip-on assembly;

[0021] In the utility model, the audio clip-on dust cover can achieve the effect of contacting and connecting the clip-on assembly by rotating the extrusion assembly;

[0022] In the utility model, the clip-on assembly in the technical solution can achieve the goal of quickly fixing the dust cover in the positioning ring. Compared with the screw connection, the connection is faster and more convenient. At the same time, the positioning assembly can be used to align the dust cover and the clip-on assembly in the positioning ring. When the dust cover needs to be removed, the clip-on assembly can be squeezed outward to release the connection of the clip-on assembly, making it easier to remove the dust cover.
