Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of car audio, specifically is a kind of anti-vibration composite basin structure for car audio. BACKGROUND

[0002] As an important part of modern car interior, car audio not only bears the function of providing entertainment and navigation information, but also is one of the key factors to improve driving experience. Among them, the audio basin body as the core component of sound output, its performance directly affects the sound quality effect. In the process of driving, due to uneven road surface, engine vibration and other factors, the audio basin body will be affected by continuous and complex vibration, resulting in sound distortion, resonance aggravation and other problems. Therefore, it is particularly important to develop an anti-vibration composite basin structure that can effectively resist vibration and maintain sound quality stability. This structure aims to improve the anti-vibration performance of the audio basin body through advanced material science and structural design, to ensure that high-quality sound effects can be output under various road conditions, meeting consumers' higher requirements for car audio.

[0003] Traditional car audio basin bodies mostly use single-layer materials or simple structural design, which cannot effectively cope with complex vibration environment. On the one hand, single-layer materials often lack sufficient rigidity and toughness, and are prone to deformation under vibration, affecting sound quality performance; on the other hand, simple structural design cannot effectively disperse vibration energy, leading to frequent resonance, further reducing sound quality clarity. In addition, the performance of traditional basin body will gradually decline during long-term use due to vibration fatigue and wear, which may even cause more serious sound quality problems. These problems not only affect the auditory enjoyment of drivers, but also limit the development and innovation of car audio technology. Therefore, to overcome the shortcomings of traditional technology and develop a new type of car audio basin body structure with higher anti-vibration performance and sound quality stability has become an urgent demand in the industry. Therefore, we propose an anti-vibration composite basin structure for car audio. SUMMARY

[0004] In view of the shortcomings of the prior art, the utility model provides an anti-vibration composite basin structure for car audio, which solves the above problems.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an anti-vibration composite basin structure for car audio, comprising a shell, a base fixedly connected to the inner wall bottom of the shell, a substrate layer provided on the top of the base, an enhanced layer fixedly connected to the top of the substrate layer, an anti-vibration layer provided on the inner wall top of the enhanced layer, the anti-vibration layer top extending to the top of the enhanced layer, an anti-vibration layer fixedly connected to the top of the shell, the anti-vibration layer bottom one end sleeved in the inner wall one end of the enhanced layer and the substrate layer, and the anti-vibration layer top and the outer wall one end of the basin body bottom in frictional contact.

[0009] Preferably, the housing top is sleeved with a sealing sleeve ring, and the inner wall top of the sealing sleeve ring is fixedly connected with a sealing rubber ring.

[0010] Preferably, eight fixed holes are formed in the top of the sealing sleeve ring, and the fixed holes extend to the top of the housing.

[0011] Compared with the prior art, the anti-shock composite basin structure for the automobile sound system has the following beneficial effects:

[0012] 1. The anti-shock composite basin structure for the automobile sound system has a multi-layer structure, including a carbon fiber base layer, a polyimide reinforcing layer, and a silicone rubber shock-resistant layer. The device can efficiently absorb and disperse vibration energy, significantly reduce resonance, and maintain clear and stable sound quality. Compared with traditional single-layer or simple-structure basin bodies, the anti-shock performance has a qualitative leap.

[0013] 2. The anti-shock composite basin structure for the automobile sound system effectively prevents external noise interference and internal sound leakage through the design of the sealing sleeve ring and the sealing rubber ring, further improving the sound insulation performance and sound quality purity of the sound system. This is crucial for improving the comfort level in the cockpit.

[0014] 3. The anti-shock composite basin structure for the automobile sound system improves the structural strength of the basin body and enhances its resistance to vibration fatigue and wear during long-term use through the design of the arch-shaped support structure and the equidistant honeycomb-shaped reinforcing layer. This means that the device can maintain stable performance in harsh vibration environments and prolong its service life. BRIEF DESCRIPTION OF DRAWINGS
