Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of channel modules, and particularly relates to a channel module with a noise reduction structure. Background Technique
[0002] In today's highly information-based society, the rapid development of communication technology has made the transmission of information more convenient and efficient. In this process, as one of the core components of the communication system, the channel module undertakes the key tasks of signal transmission, processing, and conversion. The quality of its performance directly determines the stability, reliability, and data transmission accuracy of the entire communication system.
[0003] Common channel modules lack effective noise reduction structure design. External environmental noise easily enters the module directly, interfering with signal transmission and processing. In noisy industrial environments or places with complex electromagnetic environments, external noise will seriously affect the working performance of the channel module, resulting in problems such as signal distortion and increased bit error rate. At the same time, the coupling of electromagnetic noise will also interfere with the internal electronic components of the module, affecting their normal operation. For this reason, we propose a channel module with a noise reduction structure. Content of the Utility Model
[0004] The purpose of the utility model is to provide a channel module with a noise reduction structure to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A channel module with a noise reduction structure includes a noise reduction cover and a channel module body. A noise reduction box is installed inside the noise reduction cover, and a shielding cover is installed inside the noise reduction box. The shielding cover covers the outside of the noise reduction cover.
[0006] A noise reduction cavity is opened inside the noise reduction box, and a number of noise reduction components are installed inside the cavity of the noise reduction cavity.
[0007] Preferably, the noise reduction cover is made of foam material.
[0008] Preferably, the shielding cover is made of permalloy material.
[0009] Preferably, the noise reduction component includes a plurality of sound absorption covers. One of the sound absorption covers is fixedly installed on the inner wall of the noise reduction cavity. A plurality of connecting rods are installed between adjacent two sound absorption covers, and sound absorption cotton is installed inside the sound absorption cover.
[0010] Preferably, the sound absorption cover is in a hollow frustum shape, and the opening of the sound absorption cover faces outward.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The channel module with a noise reduction structure has a noise reduction cover made of foam material covering the outside of the channel module body, which has a certain effect of eliminating noise. The hollow noise reduction box further eliminates the influence of external noise on the inside of the channel module body. Moreover, multiple double-layer sound absorption covers enable the noise to be reflected multiple times in the cavity, and the sound waves will interfere with and attenuate each other during the reflection process, further reducing the influence of noise on the channel module body, thereby ensuring the stability of the operation of the channel module body.
[0013] 2. The channel module with a noise reduction structure covers the channel module body with a metal cover having a high magnetic permeability, thereby reducing the communication noise of the channel module body in a strong magnetic environment. Brief Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Embodiment 1
[0022] Please refer to Figures 1-5 As shown, the present utility model provides a channel module with a noise reduction structure, including a noise reduction cover 1 and a channel module body 5. A noise reduction box 2 is installed inside the noise reduction cover 1, a shielding cover 4 is installed inside the noise reduction box 2, and the shielding cover 4 covers the outside of the noise reduction cover 1;
[0023] A noise reduction cavity 3 is opened inside the noise reduction box 2, and several noise reduction components are installed inside the cavity of the noise reduction cavity 3.
[0024] Specifically, the noise reduction cover 1 covers the outside of the channel module body 5, achieving a certain noise elimination effect. The hollow noise reduction box 2 further eliminates the influence of external noise on the inside of the channel module body 5, and multiple noise reduction components cause the noise to be reflected multiple times in the cavity. During the reflection process, the sound waves will interfere with and attenuate each other, further reducing the influence of noise on the channel module body 5, thereby ensuring the stability of the operation of the channel module body 5.
[0025] Among them: The noise reduction cover 1 is made of foam material. By covering the outside of the channel module body 5 with the foam material noise reduction cover 1, a certain noise elimination effect is achieved.
[0026] Among them: The shielding cover 4 is made of permalloy material. The shielding cover 4 has an extremely high magnetic permeability and can exhibit good magnetic conductivity in a weak magnetic field.
[0027] Among them: The noise reduction components include multiple sound absorption covers 6. One sound absorption cover 6 is fixedly installed on the inner wall of the noise reduction cavity 3. A plurality of connecting rods 8 are installed between two adjacent sound absorption covers 6. Sound-absorbing cotton 7 is installed inside the sound absorption cover 6. The sound absorption cover 6 is in the shape of a hollow frustum of a cone, and the opening of the sound absorption cover 6 faces outward. After the noise enters the multiple double-layer sound absorption covers 6, it will be reflected multiple times in the cavity. During the reflection process, the sound waves will interfere with and attenuate each other. When leaving the sound absorption cover 6, the noise passes through the sound-absorbing cotton 7 for further noise reduction, further reducing the influence of noise on the channel module body 5.
[0028] Working principle: The utility model is a channel module with a noise reduction structure. By covering the outside of the channel module body 5 with the foam material noise reduction cover 1, a certain noise elimination effect is achieved. The hollow noise reduction box 2 further eliminates the influence of external noise on the inside of the channel module body 5. And the multiple double-layer sound absorption covers 6 cause the noise to be reflected multiple times in the cavity. During the reflection process, the sound waves will interfere with and attenuate each other, further reducing the influence of noise on the channel module body 5, thereby ensuring the stability of the operation of the channel module body 5;
[0029] Covering the channel module body 5 with a metal cover with high magnetic permeability, thereby reducing the communication noise of the channel module body 5 in a strong magnetic environment.
