[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figures 1-5 This utility model provides an embodiment of a computer server noise reduction and protection mechanism, including a ring-shaped protective frame fitted on the outside of the server; the protective frame includes a back plate 1, a protective arm assembly 2, a support assembly 3, and a sound-absorbing module 4; retractable protective arm assemblies 2 are symmetrically arranged on both sides of the back plate 1, and a support assembly 3 for stabilizing the server legs is fixedly arranged at the bottom of the back plate 1; a sound-absorbing module 4 is integrated at the center of the back plate 1.

[0025] Please see Figures 1-3 In this embodiment, the protective arm assembly 2 includes an inner plate 201 and an outer plate 202 nested together; the outer plate 202 is hollow; the inner plate 201 and the outer plate 202 are connected by a plurality of telescopic springs 203 with dampers.

[0026] Two sets of gears 101 are symmetrically pivotally connected on the back plate 1. The gears 101 mesh with a rack 102 fixed to the inner plate 201. The back plate 1 is connected to the protective arm assembly 2 through the meshing gears 101 and rack 102. A spring damper 103 is fixedly connected between the inner plate 201 and the end of the back plate 1. A through-hole cable outlet 104 is opened on the surface of the back plate 1.

[0027] The inner plate 201 is provided with a spring buckle 204 at its end, and the outer plate 202 is provided with a multi-level inlay hole 205 for engaging the spring buckle 204 at its end. The inner plate 201 is connected to the outer plate 202 by engaging the spring buckle 204 with the inlay hole 205 and limiting its position.

[0028] Two sets of metal clips 206 are symmetrically arranged at the front end of the outer panel 202; a spring clip 207 is provided at the bottom end of the outer panel 202; a composite sound insulation layer 208 is adhered to the inner surface of both the inner panel 201 and the outer panel 202. The composite sound insulation layer 208 includes a sound insulation felt layer close to the inner wall of the outer panel 202 and a corrugated sponge absorption layer covering the outer layer.

[0029] Please see Figures 3-5In this embodiment, the support component 3 includes a support plate 301 and a side slide groove 302; the upper end of the support plate 301 is provided with multiple sets of clip holes 303 for adapting to the server legs, the side slide groove 302 is provided with a groove that cooperates with the spring clip 207, and a rubber layer 304 is pasted on the bottom of the support component 3, and the bottom surface of the rubber layer 304 is provided with anti-slip texture.

[0030] The noise reduction module 4 includes a preamplifier 401 electrically connected to each other for collecting noise signals, an audio processor 402 for processing noise, and a speaker 403 for outputting reverse sound wave signals.

[0031] When using this mechanism, the installer holds the upper end of the outer plate 202 and pulls it outward. As the outer plate 202 moves axially, it drives the inner plate 201 connected to it to move synchronously. The inner plate 201 drives the gear 101 to rotate in the opposite direction through the rack 102 fixed to its surface, causing the symmetrically arranged protective arm assembly 2 to move in the opposite direction, forming a space that accommodates the width of the server. The computer server legs are vertically inserted into the locking holes 303 of the support plate 301 to complete the longitudinal positioning. After the outer plate 202 is released, the spring damper 103 between the inner plate 201 and the back plate 1 generates an elastic return force, driving the protective arm assembly 2 to retract towards the side wall of the server. This makes the inner plates 201 on both sides fit tightly against the side wall of the server, completing the lateral fixation. At the same time, the spring locking block 207 at the bottom of the outer plate 202 is inserted into the lateral sliding groove 302 of the support assembly 3 to provide longitudinal guidance.

[0032] Continue pulling the outer panel 202 to the outermost front face of the server. When the telescopic spring 203 between the outer panel 202 and the inner panel 201 returns to its original position, the front metal clip 206 snaps onto the front panel of the server, forming a longitudinal constraint. At this time, the server is fixed in the protective frame. The protective arm assemblies 2 on both sides can provide anti-collision when the server is kicked. The composite sound insulation layer 208 inside the protective arm assembly 2 not only provides sound insulation but also effectively buffers external impacts. The bottom surface of the support assembly 3 uses a rubber layer 304 with anti-slip texture, which effectively increases the friction with the ground and prevents the server from shifting.

[0033] The front microphone 401 collects low-frequency noise signals in the server in real time. The audio processor 402 quickly analyzes the noise signals and generates sound wave signals with the same frequency and equal amplitude but opposite phase. These signals are output through the speaker 403 and superimposed on the original noise sound waves. Because they are opposite in phase, they cancel each other out.

[0034] It can use EarthMount PDM microphone and TS472 ultra-low noise microphone preamplifier, paired with A-59 dual-channel audio processor 402 with FPGA unit and wafer-level speaker 403 to achieve millisecond-level synchronization between reverse sound wave and microphone acquisition signal, covering signal from 20Hz to 20kHz, and ensuring effective cancellation of mid-low frequency noise.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
