Description

Technical Field

[0001] The utility model relates to the technical field of shockproof and noise-reducing paper cover equipment, in particular to a shockproof and noise-reducing loudspeaker paper cover. Background Art

[0002] In the field of audio technology, the sound quality and durability of speakers have always been the focus of users. During use, traditional speakers are often disturbed by external environmental noise and the vibration generated by the speaker itself, resulting in reduced sound quality, increased noise, and even damage to the internal components of the speaker, shortening its service life. In order to solve these problems and enhance the user's listening experience, it is particularly important to design a speaker paper cover that can effectively reduce noise and prevent shock.

[0003] Currently, the speaker paper covers on the market mostly focus on dust prevention and protection of internal components, with relatively few designs in terms of noise reduction and shock absorption. Although some high-end speaker products reduce noise and vibration by optimizing internal structure and material selection, these measures are often costly and difficult to popularize across all product lines.

[0004] In view of this, the existing structure and defects are studied and improved, and a shock-proof and noise-reducing loudspeaker paper cover is provided to achieve the purpose of being more practical. Utility Model Content

[0005] (1) Technical problems solved

[0006] In view of the deficiencies in the prior art, the present invention provides a shockproof and noise-reducing loudspeaker paper cover, which solves the above-mentioned problems.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a shock-proof and noise-reducing speaker paper cover, comprising a dustproof net, the outer wall of the dustproof net being connected to the paper cover, and the lower end of the paper cover being connected to a noise reduction device, and the outer wall of the noise reduction device being connected to a connecting ring, and a shock-absorbing device being provided on the outer surface of the connecting ring.

[0009] Preferably, a partition is provided inside the noise reduction device, and a consonant layer is provided at a side end of the partition, and a spiral rebound layer is provided at a side end of the consonant layer, and a conical sound-absorbing layer is provided at a side end of the spiral rebound layer.

[0010] Preferably, the partition, the auxiliary sound layer, the spiral rebound layer and the conical sound-absorbing layer are all fixedly connected to the inner wall of the conical sound-absorbing layer.

[0011] Preferably, a plurality of through holes are provided inside the spiral rebound layer and the conical sound-absorbing layer.

[0012] Preferably, the outer surface of the connecting ring is fixedly connected to a fixing block, the upper end of the fixing block is fixedly connected to a spring, and the top end of the spring is fixedly connected to a rubber block.

[0013] Preferably, there are several shock absorbing devices, and all of them are equal in size.

[0014] Preferably, the shock absorbing devices are distributed in a ring shape with equal intervals.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a shockproof and noise-reducing loudspeaker paper cover, which has the following beneficial effects:

[0017] 1. The built-in noise reduction device effectively reduces noise interference during sound propagation. The multi-layered structure within the noise reduction device - including baffles, consonant layer, spiral rebound layer and conical sound-absorbing layer - works together to finely process the sound. The consonant layer can adjust the sound spectrum to make the sound quality fuller; the spiral rebound layer uses its elastic material to absorb and disperse sound wave energy, effectively reducing sound reflection and resonance; and the conical sound-absorbing layer further guides and dissipates sound waves, especially high-frequency noise, thereby significantly improving the clarity and purity of the sound quality. In addition, the through-hole design inside the spiral rebound layer and conical sound-absorbing layer not only ensures the transparency of the sound, but also enhances the noise reduction effect, making the final output sound more natural and pleasant.

[0018] 2. In order to deal with the vibration problem generated when the speaker is working, the paper cover is equipped with shock-absorbing devices on the outer surface of the connecting ring. These shock-absorbing devices are composed of fixed blocks, springs and rubber blocks, which are distributed in a ring with equal intervals to form a stable shock-absorbing system. When the speaker is working, the vibration generated is first received by the connecting ring and transmitted to the shock-absorbing device. The elastic deformation of the spring and rubber block can effectively absorb and disperse the vibration energy, significantly reducing the overall vibration amplitude of the speaker. This not only reduces the noise and distortion caused by vibration, but also protects the internal components of the speaker from damage, extending the service life of the product. Therefore, this shock-proof and noise-reducing speaker paper cover not only provides high-quality sound quality but also ensures the stability and durability of the speaker.

[0027] Furthermore, a plurality of through holes 305 are formed inside the spiral rebound layer 303 and the conical sound-absorbing layer 304 .

[0028] Furthermore, the outer surface of the connecting ring 4 is fixedly connected to a fixing block 503, and the upper end of the fixing block 503 is fixedly connected to a spring 502, and the top end of the spring 502 is fixedly connected to a rubber block 501, which significantly reduces the overall vibration amplitude of the speaker, reduces noise and distortion caused by vibration, and protects the internal components of the speaker from damage.

[0030] Furthermore, the shock absorbing devices 5 are distributed in a ring shape with equal intervals.

[0031] Working principle: As the outermost layer of the speaker paper cover, the dustproof net 1 mainly prevents dust and debris from entering the speaker and protects the internal structure of the speaker, while maintaining the permeability of the sound. The paper cover 2 serves as the connecting part between the dustproof net 1 and the noise reduction device 3. It not only enhances the stability of the structure, but also serves as the initial channel for sound propagation. Its material and design contribute to the uniform diffusion of sound. As the basic structure of the noise reduction device 3, the partition 301 divides the internal space and provides support for the subsequent noise reduction layer. The consonant layer 302 is designed to adjust the spectral characteristics of the sound. Through specific materials and structures, it enhances or weakens the sound of a specific frequency to achieve the purpose of optimizing the sound quality. The spiral rebound layer 303 is made of elastic material and can absorb and disperse The through-hole 305 inside the speaker 304 not only ensures the permeability of the sound, but also enhances the sound absorption effect. The conical sound-absorbing layer 304 is the innermost layer of the noise reduction device 3. The conical sound-absorbing layer 304 uses the special cone structure to further guide and dissipate the sound waves, especially the high-frequency noise, so that the output sound is purer and more natural. Similarly, the through-hole 305 inside the speaker 304 also plays an important role in sound transmission and noise reduction. When the speaker is working, the vibration generated is transmitted to the shock-absorbing device 5 through the connecting ring 4. The elastic deformation of the spring 502 and the rubber block 501 can effectively absorb and disperse the vibration energy, thereby significantly reducing the overall vibration amplitude of the speaker, reducing the noise and distortion caused by vibration, and protecting the internal components of the speaker from damage.
