Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model. It should be noted that the embodiments in the utility model and the features and technical schemes in the embodiments can be combined with each other without conflict. It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0027] Embodiment 1: please refer to Figures 1-5 A noise reduction structure of electronic communication equipment, including electronic communication equipment shell 1, the noise reduction plate 2 is arranged in the electronic communication equipment shell 1, the transverse noise reduction corrugation 201 is arranged in the transverse direction of the noise reduction plate 2, the longitudinal noise reduction corrugation 202 is arranged in the longitudinal direction of the noise reduction plate 2, the noise reduction cotton 3 is arranged in the transverse noise reduction corrugation 201 and the longitudinal noise reduction corrugation 202, and the sound absorption micropore 4 is arranged on the both sides of the electronic communication equipment shell 1.

[0028] The acoustic reflection plate 5 is arranged on the front side of the electronic communication equipment shell 1. The sound insulation metal mesh 6 is arranged below the electronic communication equipment shell 1. The sound wave reflection cover 7 is arranged on the outer surface of the sound insulation metal mesh 6. The sound insulation foam board 8 is arranged on the outer surface of the sound wave reflection cover 7. The sound absorption fiberboard 9 is arranged below the acoustic reflection plate 5. The sound-absorbing cotton 10 is arranged in the sound absorption fiberboard 9. The support rod 11 is arranged below the electronic communication equipment shell 1, and the shock-absorbing rubber pad 12 is arranged below the support rod 11.

[0029] The working principle of the noise reduction structure of the electronic communication device is as follows: when the electronic communication device is working, sound waves will be generated. The sound-absorbing micro holes 4 on both sides of the device shell first absorb the sound waves preliminarily, reducing a part of the noise. After the sound waves enter the interior of the device, they encounter the noise reduction plate 2. The transverse noise reduction corrugations 201 and the longitudinal noise reduction corrugations 202 arranged transversely and longitudinally on the noise reduction plate 2 increase the contact area of the sound waves with the noise reduction plate 2. The noise reduction cotton 3 arranged in the corrugations further absorbs the sound wave energy, playing a noise reduction role.

[0030] At the same time, the acoustic reflection plate 5 on the front side of the electronic communication device shell 1 reflects part of the sound waves back, reducing the propagation of the sound waves. The sound-absorbing fiber plate 9 below the acoustic reflection plate 5 absorbs the reflected sound waves and the sound waves that are not reflected, and the sound-absorbing cotton strip 10 inside the sound-absorbing fiber plate 9 enhances the sound-absorbing effect.

[0031] The sound-absorbing metal mesh 6 below the device shell plays a certain barrier role for sound waves. The sound wave reflection cover 7 on the outer surface of the sound-absorbing metal mesh 6 reflects the sound waves back, further reducing the propagation of the sound waves. The sound-absorbing foam plate 8 on the outer surface of the sound wave reflection cover 7 absorbs the reflected sound wave energy, reducing the noise.

[0032] During the operation of the device, vibrations may occur, and the shock-absorbing rubber pad 12 below the support rod 11 can reduce the vibration of the device, thereby reducing the noise generated by the vibration.

[0033] In summary, the noise reduction structure of the electronic communication device effectively reduces the noise generated by the electronic communication device during operation through sound absorption, sound insulation, sound wave reflection, and vibration reduction.

[0034] The working process of the noise reduction structure of the electronic communication device is as follows: when the electronic communication device is running, the sound waves generated first contact the sound-absorbing micro holes 4 on both sides of the electronic communication device shell 1, and the sound-absorbing micro holes 4 preliminarily absorb part of the sound waves. The remaining sound waves enter the interior of the electronic communication device shell 1 and encounter the noise reduction plate 2 arranged inside. The transverse noise reduction corrugations 201 and the longitudinal noise reduction corrugations 202 on the noise reduction plate 2 increase the contact area with the sound waves, and the noise reduction cotton 3 inside the corrugations absorbs the sound wave energy, achieving further noise reduction.

[0035] Part of the sound waves continue to propagate forward and encounter the acoustic reflection plate 5 on the front side of the electronic communication device shell 1, which reflects part of the sound waves back.

[0036] The reflected sound waves and the sound waves that are not reflected reach the sound-absorbing fiber plate 9 below the acoustic reflection plate 5, which absorbs these sound waves, and the sound-absorbing cotton strip 10 inside enhances the sound-absorbing effect.

[0037] At the same time, the sound wave will also propagate below the device, encountering the sound insulation metal mesh 6 below the electronic communication device shell 1, which has a certain blocking effect on the sound wave.

[0038] The sound wave reflection cover 7 on the outer surface of the sound insulation metal mesh 6 reflects the sound wave passing through the sound insulation metal mesh 6 back, reducing the continuous propagation of the sound wave.

[0039] The sound insulation foam board 8 on the outer surface of the sound wave reflection cover 7 absorbs the reflected sound wave energy, further reducing noise.

[0040] During the operation of the electronic communication device, the vibration generated may be buffered and reduced by the shock-absorbing rubber pad 12 below the support rod 11, reducing the noise generated by the vibration.
