[0002] Burn-in test chambers, also known as aging chambers, are indispensable key testing equipment in the electronics and communications industry, primarily used for pre-burn-in testing of semi-finished or finished products. Their core principle is to accelerate the early failure process of electronic components by simulating harsh environments such as high temperatures, thereby screening out products with potential defects and effectively improving the reliability and stability of batch products, providing strong assurance for product quality before shipment. Existing burn-in test chambers are mainly divided into two types: constant temperature burn-in test chambers and constant humidity burn-in test chambers. These two types are widely used in various fields based on their different testing requirements. Among them, electronic equipment such as computers, servers, and power supplies, automotive electronic components, and semiconductor chips all need to undergo environmental reliability verification in burn-in test chambers before leaving the factory to ensure their stability and durability in actual use, avoiding safety hazards and economic losses caused by early failure.

[0003] In the audio industry, aging chambers are mainly used for aging tests of audio products such as speakers, and are a crucial part of audio product quality control. During the testing process, hundreds of audio products work simultaneously, generating high-intensity noise that significantly interferes with the surrounding environment of the aging chamber. Therefore, there is an urgent need for a soundproofing device for automated aging chambers. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0018] like Figure 1 and 2 As shown, this embodiment provides a sound insulation device for an automatic aging cabinet, comprising: The cabinet includes an inlet 5, an outlet 3, and an observation window 3. The sound insulation components include a sound insulation curtain, a transparent sound insulation panel, sound insulation cotton, and a sealing strip. The sound insulation curtain is installed at the inlet 5 and the outlet, the transparent sound insulation panel is installed at the observation window 3, the area on the inner wall of the cabinet except for the observation window 3 is equipped with sound insulation cotton, and the gaps in the cabinet are equipped with sealing strips.

[0019] When using the sound insulation device for the automatic aging cabinet provided by this invention, the sound insulation curtains at the inlet 5 and outlet can form a dynamic sound insulation barrier when products are loaded and unloaded, effectively blocking noise leakage; the transparent sound insulation plate at the observation window 3 can significantly reduce sound wave transmission while ensuring that operators can observe the test status inside the cabinet in real time; the sound insulation cotton laid on the inner wall of the cabinet can absorb and attenuate the noise generated by products such as audio equipment, further weakening the noise energy; the sealing strip at the gaps in the cabinet can eliminate structural sound leakage channels and achieve full-enclosure sound insulation, thereby achieving efficient noise reduction throughout the aging test of audio products, significantly reducing the noise intensity around the automatic aging cabinet 2, improving the working environment at the test site, meeting the noise control requirements of the automated aging production line for audio products, and not affecting the normal feeding, discharging and observation functions of the aging cabinet 2, thus combining practicality and reliability.

[0020] The sound insulation cotton consists of a honeycomb core panel, a fiber sound-absorbing layer, and a PVC board layer arranged sequentially from the inside out, forming a multi-level sound absorption and insulation system. It utilizes the honeycomb core panel to improve the structural rigidity and damping performance, and achieves efficient absorption of mid-to-high frequency noise through the fiber sound-absorbing layer and sound-absorbing cotton. The PVC board layer effectively blocks the transmission of low-frequency noise, greatly improving the overall sound absorption and insulation performance.

[0021] A resonance device is installed on the side of the PVC board away from the fiber sound-absorbing layer. The resonance device includes resonant spikes, a reinforcing frame, and a resonant plate. The resonant plate is connected to the PVC board, the reinforcing frame is placed on the resonant plate, and multiple resonant spikes are provided on the resonant plate. This design addresses low-frequency and resonant noise commonly found in dissipative audio tests, further broadening the noise reduction frequency range and enhancing adaptability to complex noise spectra.

[0022] Sound-absorbing cotton is placed on the side of the honeycomb core panel away from the fiber sound-absorbing layer.

[0023] The transparent soundproof panel comprises at least two layers of transparent glass, with a vacuum zone between adjacent glass panels. By utilizing the vacuum layer to block the sound wave propagation medium, the sound insulation is significantly improved while maintaining a clear field of view, effectively solving the problem of insufficient sound insulation performance of traditional observation windows.

[0024] A buffer is installed between the sound insulation cotton and the inner wall of the cabinet. The buffer can be a coil spring or a rubber block. One end of the buffer is connected to the PVC board layer on the sound insulation cotton, and the other end is connected to the inner wall of the cabinet. An elastic buffer structure is formed between the sound insulation cotton and the inner wall of the cabinet, which weakens the transmission of sound and vibration in the cabinet structure, avoids secondary structural noise caused by vibration, and improves the stability and sound insulation effect of the overall sound insulation system.

[0025] Feeding device 1 and discharging device 4 are respectively installed at both ends of the cabinet. Feed inlet 5 and discharging outlet 4 are located on the cabinet at positions corresponding to feeding device 1 and discharging device 4, respectively. Soundproof curtains are installed at feeding inlet 5 and discharging outlet 4. The soundproof curtains consist of multiple curtains arranged sequentially along the horizontal direction. This ensures smooth passage of products during feeding and discharging while forming a continuous, flexible sound barrier. The curtains use a composite structure of double-layer Oxford cloth sandwiched with butyl rubber sound insulation felt, possessing both good mechanical strength and excellent sound insulation performance, further suppressing noise leakage from feeding inlet 5 and discharging outlet 4.

[0026] This invention employs a combination of technologies, including multi-layered composite sound absorption and insulation, resonant sound absorption, vacuum sound insulation, flexible sealing, and vibration damping, to achieve wide-frequency noise control. The overall noise reduction can reach over 30 decibels, ensuring that the noise level around the automatic aging chamber 2 does not exceed 80 decibels. While achieving efficient noise reduction, this device does not affect the automated operation of the aging chamber 2, real-time visual monitoring, or continuous product flow, significantly improving the acoustic environment quality and operational safety under audio product aging testing conditions.

[0027] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope.
