Description

Technical Field

[0001] This utility model relates to the field of audio analyzer technology, and in particular to an anti-interference power supply for an audio analyzer. Background Technology

[0002] An audio analyzer is a professional measurement device used to analyze and evaluate various characteristics of audio signals, including frequency response, distortion, dynamic range, and noise level. It is widely used in music production, broadcasting, film and television post-production, and audio testing, providing accurate audio data to help engineers and technicians optimize audio systems and improve sound quality. Through advanced signal processing technology, audio analyzers can display complex audio waveforms and spectra in real time, enabling users to intuitively identify and adjust problems in audio signals.

[0003] In existing technologies, although the design of built-in motherboards integrates a variety of advanced functions, the disassembly process is extremely cumbersome, causing considerable inconvenience for maintenance and upgrades. The complex internal structure and tight component layout require a lot of time and effort to disassemble, especially for users without professional skills, making it even more difficult. In addition, the tight integration of the motherboard with other components can lead to damage to components during disassembly or poor contact after installation, which further increases the risk and cost of maintenance. Furthermore, frequent disassembly not only reduces the efficiency of the equipment but also affects its long-term stability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-interference power supply for an audio analyzer.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-interference power supply for an audio analyzer, comprising an anti-interference power supply housing, a front panel detachably connected to the front of the anti-interference power supply housing, an internal motherboard provided on the inner wall of the anti-interference power supply housing, a motherboard mounting clip fixed at the bottom corner of the internal motherboard, a clip limiting groove provided on the inner wall of the anti-interference power supply housing, a first limiting shaft and a second limiting shaft provided inside the clip limiting groove, a first sliding block fixed on both sides of the first limiting shaft, the first sliding block sliding on the inner wall of the clip limiting groove, a first spring fixed on both sides of the first sliding block, the other end of the first spring fixed to the inner wall of the clip limiting groove, a second sliding block fixed on both sides of the second limiting shaft, the second sliding block sliding on the inner wall of the clip limiting groove, a second spring fixed on both sides of the second sliding block, the other end of the second spring fixed to the inner wall of the clip limiting groove.

[0006] Preferably, the inner wall of the anti-interference power supply housing is provided with a cooling fan, a through sliding groove is provided through the back of the anti-interference power supply housing, a non-through limiting groove is provided on the back of the through sliding groove, a sliding groove is provided inside the cooling fan, a sliding limiting member is slidably connected to the inner wall of the sliding groove, a third spring is provided on the surface of the sliding limiting member, a limiting block is fixed on one side of the sliding limiting member, and a rear ventilation hole is provided on the back of the anti-interference power supply housing. In the prior art, the cooling fan design of the power supply motherboard of the audio analyzer has the problem of insufficient ease of disassembly. This defect is particularly prominent in the process of equipment maintenance and upgrade. Since the cooling fan is usually fixed on the motherboard, when users need to clean, replace or repair the fan, they often need to disassemble the entire device. This not only increases the complexity of operation, but also leads to damage to other components. In addition, long-term use makes it easy for dust to accumulate inside the fan, affecting the heat dissipation effect. The inconvenient disassembly design increases the difficulty of equipment maintenance. To address this problem, this utility model adopts a detachable cooling fan structure. When it is necessary to disassemble the cooling fan, pull the limiting block. At this time, the sliding limiting member squeezes the first spring. With three springs, the limiting block is disengaged from the non-penetrating limiting groove. Then, the limiting block is rotated until it coincides with the penetrating sliding groove. At this point, under the action of the third spring, the limiting block slides out of the limiting groove, significantly improving the maintenance efficiency and user experience of the equipment. By adopting a modular design or quick disassembly mechanism, users can easily clean and replace the fan, avoiding the tedious process of disassembling the entire device. This not only reduces the potential risk of damage but also effectively improves heat dissipation, ensuring the stability and performance of the equipment during long-term use. This improvement will greatly enhance the operability of the audio analyzer during maintenance and upgrades, thereby improving overall efficiency and user satisfaction.

[0007] Preferably, the anti-interference power supply housing is made of aluminum. In the prior art, audio analyzers have significant drawbacks in terms of power supply anti-interference, mainly in their sensitivity to external power noise. Audio analyzers typically rely on external power supplies, and this design makes it easy for power noise and electromagnetic interference to be conducted to the analysis circuit through the power supply lines, thus affecting the accuracy of measurement results. Especially in high-sensitivity measurement applications, even small power fluctuations can cause signal distortion, reducing the analyzer's performance. Furthermore, existing power supply designs often fail to effectively filter high-frequency noise, increasing uncertainty in signal processing. To address these issues, this invention employs an anti-interference structure. Because the anti-interference power supply housing is made of aluminum, aluminum, as a conductor, can form a shielding layer, blocking external electromagnetic interference and reducing electromagnetic radiation generated by the internal circuitry, thereby ensuring signal stability and measurement accuracy. In addition, aluminum is lightweight, easy to process, and dissipates heat, significantly reducing the conduction of electromagnetic interference, thus improving signal stability and measurement accuracy, especially in high-sensitivity measurement applications. The ultimate goal is to achieve higher signal purity and reliability, improving the overall performance of the audio analyzer and ensuring accurate measurement results in complex environments.

[0008] Preferably, an auxiliary pull block is fixed to one side of the limiting block. The auxiliary pull block improves the ease of operation of the limiting block, making it easier to pull out when needed, thereby improving efficiency and convenience during use. This not only enhances the functionality of the limiting block but also optimizes its overall mechanical performance.

[0009] Preferably, the recessed part of the motherboard mounting clip is arc-shaped. This improves the aesthetics of the clip and greatly enhances the ease of installation and removal, allowing users to operate more efficiently and reducing the cumbersome steps caused by traditional designs.

[0010] Preferably, the top of the anti-interference power supply housing is fixed with heat dissipation fins. This effectively improves the heat dissipation performance of the device, enabling it to dissipate the heat generated by the system in a timely manner, thereby avoiding performance degradation and potential failures caused by overheating, and extending the service life of the device. At the same time, the design of the heat dissipation fins also optimizes airflow, further ensuring the stability and reliability of the power supply under high load operation.

[0011] Preferably, the anti-interference power supply housing has side ventilation holes arrayed on both sides, which significantly improves air circulation and increases internal cooling effect. By providing more ventilation holes, the internal temperature of the housing can be effectively reduced, reducing heat accumulation during high-load operation and ensuring that the power supply can maintain stable operation in various environments. In addition, the improved ventilation structure can also reduce the accumulation of dust and dirt, further improving the reliability and service life of the equipment.

[0012] Beneficial effects:

[0013] 1. In existing technologies, while the built-in motherboard design integrates various advanced functions, its disassembly process is exceptionally cumbersome, causing significant inconvenience for maintenance and upgrades. The complex internal structure and tightly packed component layout require a substantial investment of time and effort for disassembly, especially for users without professional technical skills. Furthermore, the tight integration of the motherboard with other components can lead to damage to components during disassembly or poor contact after installation, further increasing the risk and cost of maintenance. In addition, frequent disassembly not only reduces the efficiency of the equipment but also affects its long-term stability. To address these issues, this utility model adopts a convenient motherboard disassembly structure, significantly improving the ease of disassembly. This not only significantly reduces the difficulty of maintenance and upgrades and enhances the user experience but also reduces the risk of damage during disassembly and subsequent maintenance costs. This improvement will enhance the reliability of the equipment, ensuring its long-term stable operation, while also improving user efficiency, making the product more competitive in the market. Moreover, the simplified disassembly process will encourage more users to perform self-maintenance, promoting the sustainable development of the equipment.

[0014] 2. In existing technologies, the cooling fan design of the power supply motherboard of audio analyzers suffers from insufficient ease of disassembly. This deficiency is particularly prominent during equipment maintenance and upgrades. Since the cooling fan is usually fixed to the motherboard, users often need to disassemble the entire device to clean, replace, or repair the fan. This not only increases the complexity of the operation but also leads to damage to other components. In addition, prolonged use causes dust to accumulate inside the fan, affecting the heat dissipation effect. The inconvenient disassembly design increases the difficulty of equipment maintenance. To address these issues, this utility model adopts a detachable cooling fan structure, significantly improving equipment maintenance efficiency and user experience. By adopting a modular design or quick disassembly mechanism, users can easily clean and replace the fan, avoiding the cumbersome process of disassembling the entire device. This not only reduces the potential risk of damage but also effectively improves the heat dissipation effect, ensuring the stability and performance of the device during long-term use. This improvement will greatly enhance the operability of audio analyzers during maintenance and upgrades, thereby improving overall efficiency and user satisfaction.

[0015] 3. In existing technologies, audio analyzers have significant drawbacks in terms of power supply interference immunity, mainly manifested in their sensitivity to external power supply noise. Audio analyzers typically rely on external power supplies, and this design makes it easy for power supply noise and electromagnetic interference to be conducted to the analysis circuit through the power supply lines, thereby affecting the accuracy of measurement results. Especially in high-sensitivity measurement applications, even small power supply fluctuations can lead to signal distortion and reduce the performance of the analyzer. In addition, existing power supply designs often cannot effectively filter high-frequency noise, increasing the uncertainty in the signal processing process. To address these issues, this invention adopts an anti-interference structure to significantly reduce the conduction of electromagnetic interference, thereby improving signal stability and the accuracy of measurement results, especially in high-sensitivity measurement applications. The ultimate goal is to achieve higher signal purity and reliability, improve the overall performance of the audio analyzer, and ensure accurate measurement results in complex environments.

[0026] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0029] Reference Figure 1-8An anti-interference power supply for an audio analyzer includes an anti-interference power supply housing 1. A front panel 110 is detachably connected to the front of the anti-interference power supply housing 1. An internal motherboard 101 is provided on the inner wall of the anti-interference power supply housing 1. A motherboard mounting clip 102 is fixed at the bottom corner of the internal motherboard 101. A clip limiting groove 103 is formed on the inner wall of the anti-interference power supply housing 1. A first limiting shaft 104 and a second limiting shaft 105 are provided inside the clip limiting groove 103. A first sliding shaft is fixed on both sides of the first limiting shaft 104. The moving block 106 and the first sliding block 106 slide on the inner wall of the snap-fit ​​limiting groove 103. The first sliding block 106 is fixed with a first spring 107 on both sides. The other end of the first spring 107 is fixed to the inner wall of the snap-fit ​​limiting groove 103. The second limiting shaft 105 is fixed with a second sliding block 108 on both sides. The second sliding block 108 slides on the inner wall of the snap-fit ​​limiting groove 103. The second sliding block 108 is fixed with a second spring 109 on both sides. The other end of the second spring 109 is fixed to the inner wall of the snap-fit ​​limiting groove 103. While existing technologies integrate various advanced functions through built-in motherboards, their disassembly process is exceptionally cumbersome, causing significant inconvenience for maintenance and upgrades. The complex internal structure and tightly packed component layout require substantial time and effort for disassembly, especially for users without specialized technical skills. Furthermore, the close integration of the motherboard with other components can lead to damage during disassembly or poor contact after installation, further increasing repair risks and costs. In addition, frequent disassembly not only reduces equipment efficiency but also affects its long-term stability. To address this issue, this utility model employs a convenient motherboard disassembly structure. When motherboard disassembly is required, the built-in motherboard 101 is pulled. At this time, the motherboard mounting bracket 102 at the bottom of the built-in motherboard 101, under the action of the vertical force, drives the first limiting shaft 104 and the second limiting shaft 105, causing the first sliding block 106 and the second sliding block 108 at both ends to slide to both sides, thereby removing the motherboard mounting bracket 102 and completing the disassembly of the built-in motherboard 101. At this time, the first limiting shaft 104 and the second limiting shaft 105 return to their original positions under the action of the first spring 107 and the second spring 109.

[0030] The anti-interference power supply housing 1 has a cooling fan 2 on its inner wall. The back of the anti-interference power supply housing 1 has a through sliding groove 201. The back of the through sliding groove 201 has a non-through limiting groove 202. The cooling fan 2 has a sliding groove inside. The inner wall of the sliding groove is slidably connected to a sliding limiting member 203. The surface of the sliding limiting member 203 has a third spring 204. A limiting block 205 is fixed on one side of the sliding limiting member 203. The back of the anti-interference power supply housing 1 has a rear ventilation hole 206. In the existing technology, the cooling fan design of the power supply motherboard of the audio analyzer has the problem of insufficient ease of disassembly. This defect is particularly prominent in the process of equipment maintenance and upgrade. Since the cooling fan is usually fixed on the motherboard, users often need to disassemble the entire device when they need to clean, replace or repair the fan. This not only increases the complexity of operation, but also causes damage to other components. In addition, long-term use makes it easy for dust to accumulate inside the fan, affecting the heat dissipation effect. The inconvenient disassembly design increases the difficulty of equipment maintenance. To address these issues, this utility model adopts a detachable cooling fan structure. When it is necessary to disassemble the cooling fan 2, pull the limiting block 205. At this time, the sliding limiting member 203 compresses the third spring 204. After the limiting block 205 is disengaged from the non-penetrating limiting groove 202, the limiting block 205 is rotated so that the limiting block 205 coincides with the penetrating sliding groove 201. At this time, under the action of the third spring 204, the limiting block 205 slides out of the limiting position in the penetrating sliding groove 201.

[0031] The anti-interference power supply housing 1 is made of aluminum. In existing technologies, audio analyzers have significant drawbacks in terms of power supply anti-interference, primarily in their sensitivity to external power noise. Audio analyzers typically rely on external power supplies, a design that allows power noise and electromagnetic interference to easily be conducted to the analysis circuitry through the power supply lines, affecting the accuracy of measurement results. Especially in high-sensitivity measurement applications, even minor power fluctuations can cause signal distortion, reducing analyzer performance. Furthermore, existing power supply designs often fail to effectively filter high-frequency noise, increasing uncertainty in signal processing. To address these issues, this invention employs an anti-interference structure. Since the anti-interference power supply housing 1 is made of aluminum, aluminum, as a conductor, can form a shielding layer, blocking external electromagnetic interference and reducing electromagnetic radiation generated by internal circuitry, thereby ensuring signal stability and measurement accuracy. Additionally, aluminum is lightweight, easy to process, and facilitates heat dissipation.

[0032] An auxiliary pull block 3 is fixed to one side of the limit block 205. The auxiliary pull block improves the ease of operation of the limit block, making it easier to pull out when needed, thereby improving efficiency and convenience during use. It not only enhances the functionality of the limit block but also optimizes the overall mechanical performance. The motherboard mounting clip 102 has an arc-shaped recess, which improves the aesthetics of the clip and greatly enhances the ease of installation and disassembly, allowing users to operate more efficiently and reducing the cumbersome steps caused by traditional designs. The top of the anti-interference power supply housing 1 is fixed with heat dissipation fins 4, which effectively improves the heat dissipation performance of the device and can dissipate the heat generated by the system in a timely manner. The heat sink design optimizes airflow, further ensuring the stability and reliability of the power supply under high load. The anti-interference power supply housing 1 features side ventilation holes 5 on both sides, significantly improving airflow and enhancing internal cooling. Providing more ventilation holes effectively reduces the internal temperature of the housing, mitigating heat buildup under high load and ensuring stable operation in various environments. Furthermore, the improved ventilation structure reduces dust and dirt accumulation, further enhancing the reliability and lifespan of the equipment.

[0033] The working principle of this utility model is as follows: When the motherboard needs to be disassembled, the built-in motherboard 101 is pulled. At this time, the motherboard mounting bracket 102 at the bottom of the built-in motherboard 101, under the action of the vertical force, drives the first limiting shaft 104 and the second limiting shaft 105, causing the first sliding block 106 and the second sliding block 108 at both ends to slide to both sides, thereby removing the motherboard mounting bracket 102 and completing the disassembly of the built-in motherboard 101. At this time, the first limiting shaft 104 and the second limiting shaft 105 return to their original positions under the action of the first spring 107 and the second spring 109. When the cooling fan 2 needs to be disassembled, the limiting block 205 is pulled. When the sliding limiter 203 presses the third spring 204, the limiter block 205 is released from the limit of the non-penetrating limiter groove 202. Then the limiter block 205 is rotated so that the limiter block 205 coincides with the penetrating sliding groove 201. At this time, under the action of the third spring 204, the limiter block 205 slides out of the limit in the penetrating sliding groove 201. Since the anti-interference power supply housing 1 is made of aluminum, aluminum, as a conductor, can form a shielding layer to block external electromagnetic interference and reduce the electromagnetic radiation generated by the internal circuit, thereby ensuring the signal stability and measurement accuracy of the equipment. In addition, aluminum is lightweight, easy to process and dissipate heat.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
