[0002] A test chamber is a device used to eliminate external noise interference and provide sound insulation and noise reduction. It is widely used in acoustic testing of audio devices such as electronic equipment. To ensure the accuracy of audio device testing before leaving the factory, the sound insulation effect of the soundproof chamber needs to be improved.

[0003] At present, most of the existing sound insulation test boxes improve the sound insulation effect inside the test box by stacking several sound-absorbing cottons on the inner wall of the box. However, this method does not improve the sound insulation effect much. Moreover, since several layers of sound-absorbing cotton are added inside the box, the product placement space inside the test box will be greatly reduced, which is not conducive to the user's placement of the product. In addition, the sound wave conduction and blocking effects of different frequencies are poor, and the overall sound insulation effect is not good. Utility Model Content

[0023] Embodiment 1: A sound insulation isolation box includes an electrical cabinet 1, a sound insulation isolation box body 2 is provided on the top of the electrical cabinet 1, an operation panel 3 is provided on the side of the electrical cabinet 1, a start button 4 is provided on the operation panel 3, an emergency stop button 5 is provided on the side of the start button 4, a drawer-type door 6 is installed on the side of the sound insulation isolation box body 2, a first filter 7 is provided on the electrical cabinet 1, an SMA filter 8 is provided on the side of the first filter 7, and a bottom mounting plate 9 is provided on the top of the electrical cabinet 1.

[0024] A drawer door inlet and outlet cylinder 10 is provided on the bottom mounting plate 9, and the drawer door inlet and outlet cylinder 10 is connected to the inner side of the drawer-type door 6. A vertically adjustable platform 11 is provided at the top of the bottom mounting plate 9, and a servo motor 12 is provided on the side of the top of the bottom mounting plate 9. A backlight panel 13 is provided above the servo motor 12, and a reflective module 14 is provided on the side of the vertically adjustable platform 11. A camera module 15 is installed on the side of the reflective module 14, and a rotating platform 16 is provided on the side of the servo motor 12. A pre-power-on module 17 is provided on the rotating platform 16.

[0025] Several support bases are evenly arranged on the sides of the bottom end of the electrical cabinet 1.

[0026] The first filter 7 and the SMA filter 8 are connected to the electrical cabinet 1 via a mounting plate provided at the bottom.

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that two limiting rods are symmetrically inserted at both ends of the side of the upper and lower adjustable platform 11.

[0028] This makes the up and down adjustable platform 11 more stable when moving up and down.

[0029] Embodiment 3: The difference between this embodiment and embodiment 1 is that the side surface of the backlight plate 13 is connected to the bottom mounting plate 9 via a support frame.

[0030] This allows the backlight panel 13 to be more stably arranged on the side of the reflective module 14 .

[0031] Embodiment 4: The difference between this embodiment and embodiment 1 is that a product placement table is provided on the side of the rotating platform 16.

[0032] This makes the test product more stable when placed in the sound insulation box 2.

[0033] In this embodiment, since most of the existing sound insulation test boxes improve the sound insulation effect inside the test box by stacking several sound-absorbing cottons on the inner wall of the box, this method does not improve the sound insulation effect much, and since several layers of sound-absorbing cotton are added inside the box, the product placement space inside the test box will be greatly reduced, which is not conducive to the user's placement of the product, and the sound wave conduction and blocking effects of different frequencies are poor, and the overall sound insulation effect is not good.

[0034] In summary, in a specific implementation, by providing a bottom mounting plate 9 on the electrical cabinet 1 and a rotating platform 16 on the bottom mounting plate 9, the user can place the audio product to be soundproofed on the rotating platform 16 by opening the drawer-type door 6 on the side of the sound insulation isolation box 2.

[0035] The detection is carried out by cooperating with the camera module 15, the reflective module 14 and the pre-power-on module 17 arranged on the side of the rotating platform 16, and the electrical cabinet 1 is also provided with a first filter 7 and an SMA filter 8. The first filter 7 and the SMA filter 8 can effectively filter out the frequency point of a specific frequency in the power line or the frequency other than the frequency point, and thus can obtain a power signal of a specific frequency more clearly, so that the detection signal in the detection process is transmitted outward more clearly and accurately.

[0036] Moreover, there is no need to set multiple layers of sound-absorbing cotton on the inner wall of the electrical cabinet 1, and the sound insulation effect inside the electrical cabinet 1 can be improved. It can conduct sound waves when testing audio products to be tested with different frequencies. At the same time, it has a better blocking effect on external sound waves, and the overall sound insulation effect is better, which is beneficial for users to perform sound insulation tests on various audio products and is convenient for users to use.
