Description

Technical Field

[0001] This utility model relates to the field of audio instrument assembly technology, and in particular to an audio analyzer assembly structure. Background Technology

[0002] An audio analyzer is a testing instrument that obtains audio characteristic parameters by analyzing audio signals. It can measure various performance parameters of audio equipment, such as frequency response, harmonic distortion, signal-to-noise ratio, and dynamic range, and perform advanced functions such as spectrum analysis, octave band analysis, and sound pressure level measurement. With the continuous development of audio technology, the requirements for the accuracy and stability of audio analyzers will become increasingly stringent. In the future, audio analyzers will adopt more advanced sensor and signal processing technologies to improve measurement accuracy and stability, providing more accurate test data for the research and development and production of audio equipment.

[0003] In existing technologies, audio analyzers, as precision audio testing instruments, face a series of complex operational challenges during installation. Firstly, their internal structure includes multiple heavy modules, especially the power module, which is not only large but also extremely heavy. This poses significant inconvenience for handling and assembly. During transport, the overall weight of the equipment and the often smooth surface treatment to reduce electromagnetic interference make it difficult for operators to grip securely, increasing the difficulty and risk of handling. Even more problematic is that while some audio analyzers are designed with handles or carrying handles for ease of movement, these seemingly thoughtful designs prove ineffective in actual use due to the equipment's excessive weight. When a single person attempts to move it,… Often, the weight exceeds the equipment's capacity, making it impossible to complete the task. Even if force is applied, the equipment is prone to becoming unbalanced and falling, with potentially disastrous consequences. When two people cooperate to move the equipment, although they can share some of the weight, the walking speed and direction of force are difficult to synchronize completely, and the equipment will inevitably sway during the process. This instability greatly increases the risk of equipment damage, especially for the handle design. If the force is uneven or an accidental collision occurs during the process, the connection between the handle and the main body of the equipment can easily break, or even worse, the metal casing can be deformed. Once this happens, it will not only affect the appearance of the equipment, but more importantly, it will damage the precision structure inside the equipment, affecting its testing performance and accuracy. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an audio analyzer assembly structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an audio analyzer assembly structure, including a main housing, with grooves provided at the top of both sides of the main housing, a curved plate fixed to the groove, a top cover fixed to the top of the curved plate, I-beam pads fixed to both sides of the inner wall of the main housing, fixing nails fixed to the surface of the I-beam pads, a screw fixing member fixed to one end of the fixing nail, and a handling handle rotatably connected to one end of the screw fixing member, and recesses provided on both sides of the main housing.

[0006] Preferably, a mounting beam is fixed to one side of the I-beam pad, and a mounting groove is provided on one side of the mounting beam. A chamber plate is fixed to the inner wall of the mounting groove, and a lifting plate is fixed to one end of the chamber plate. In the prior art, some audio analysis devices are designed to directly fix the chamber plate to the inner wall of the main housing. Although this design has its advantages in certain specific scenarios, it brings many inconveniences during device installation. Because the chamber plate is directly fixed and cannot be moved, this greatly limits the operating space inside the main housing. When installing the device or wiring, the staff will find that the available space is very limited, making the device installation extremely difficult and even requiring a lot of time and effort to complete the installation work. More seriously, this design also makes it almost impossible to change the number and position of the chamber plates on the inner wall of the main housing. Once the needs of the device change, or it needs to be adjusted according to a new usage scenario, the staff will find that they cannot flexibly adjust the configuration of the chamber plates to adapt to the new needs. This further limits the applicability of the device, making it difficult for the device to meet the personalized needs of different users. In order to address these problems, this invention... The novel approach of using mounting beams provides flexibility for staff when structuring the internal structure of the audio analyzer. They can precisely select the number of mounting beams and chamber plates based on the actual situation, ensuring a rational and efficient internal layout. Furthermore, to enhance stability and prevent deformation, additional faceplates are installed. These faceplates are designed to increase the contact area with the main housing, effectively dispersing the pressure from chamber plates housing heavier modules when the equipment tilts, preventing compression and deformation of the main housing. During installation, staff first slide the chamber plates into pre-designed mounting grooves. This step not only ensures accurate positioning of the chamber plates but also facilitates subsequent module installation. Using the mounting grooves, staff can flexibly choose the installation position of the chamber plates based on the specific location of the modules and the size of the chamber plates. Once the ideal position is determined, bolts are used to firmly fix the chamber plates to the main housing, ensuring that the chamber plates will not shift or fall off due to vibration or movement during operation, thus improving the user experience.

[0007] Preferably, a mesh plate is fixed to one end of the main housing, a convex arc plate is fixed to one end of the main housing, a toothed plate is fixed to one end of the convex arc plate, and a thickened screw is fixed to one end of the toothed plate. In the prior art, when an audio analyzer is accidentally impacted, the end plate of its main housing is often the first to be affected and is easily dented due to external force. This dent not only affects the appearance of the equipment but also damages the precision components inside, thus affecting the normal operation and service life of the equipment. In another common scenario, when the operator lifts the equipment using the handle, the side plate of the main housing tends to be squeezed towards the center due to the combined effect of upward tension and gravity. This tendency will cause the end plate to be subjected to outward tension to a certain extent, causing the end plate to bulge outward. This bulge will also negatively affect the structural stability of the equipment, causing component deformation and skewing, and even causing more serious equipment failures. To address these problems, this utility model solves them by installing a convex arc plate, achieving the effect of... The arc plate significantly increases the thickness and overall strength of the vulnerable central part of the main housing. This design not only effectively prevents the main housing from bending due to its own weight or external pressure, but also improves the equipment's impact resistance to a certain extent. Meanwhile, to improve the installation accuracy and stability of internal components, the design team also introduced a toothed plate. This carefully designed toothed plate achieves a tighter and more suitable fit with the inner wall of the main housing. This tight fit not only helps ensure the accurate positioning and stable installation of internal components, but also disperses external impact forces to a certain extent, reducing the direct impact on the main housing. Furthermore, to further enhance the structural strength of the main housing, especially in key areas such as screw holes, the design team also adopted measures to thicken the screws. By increasing the thickness of the material around the screw holes, the strength of these areas can be significantly improved, ensuring that the connection will not loosen or fail due to fatigue or deformation of the material around the screw holes during long-term use, thus extending the equipment's service life.

[0008] Preferably, the inner wall of the convex arc plate is fixed with reinforcing mesh, which improves the strength of the convex arc plate and thus extends the service life of the equipment.

[0009] Preferably, a support column beam is fixed to the top of the inner wall of the main housing, which prevents the deformation of the side plate of the main housing and thus improves the service life of the equipment.

[0010] Preferably, the bottom of the main housing is fixed with threaded nails, and the bottom of the main housing is fixed with support feet by the threaded nails, which prevents the main housing from directly contacting the ground and improves the service life of the equipment.

[0011] Preferably, a fixing plate is fixed to the other end of the main housing, which prevents the installation position of the heavy power module from deforming, thereby improving the service life of the equipment.

[0012] Beneficial effects:

[0013] 1. In existing technologies, audio analyzers, as precision audio testing instruments, face a series of complex operational challenges during installation. Firstly, their internal structure includes several heavy modules, especially the power module, which is not only large but also extremely heavy. This greatly complicates the handling and assembly of the equipment. During handling, the overall weight of the equipment and the often smooth surface treatment to reduce electromagnetic interference make it difficult for operators to grip firmly, increasing the difficulty and risk of transport. Even more problematic is that some audio analyzers are designed with handles or carrying handles for ease of movement; however, these seemingly thoughtful designs prove ineffective in actual use due to the equipment's excessive weight, making it difficult for a single person to handle. When attempting to move the equipment, it is often impossible due to the weight exceeding the equipment's capacity. Even with forced effort, the equipment is highly susceptible to imbalance and falls, with potentially disastrous consequences. While two people can share the weight when moving the equipment together, the difficulty in synchronizing walking speed and force direction inevitably leads to swaying during transport. This instability significantly increases the risk of damage, especially to the handles. Uneven force or accidental impacts during transport can easily cause the connection between the handle and the main body to break, or even more seriously, deform the metal casing. Such occurrences not only affect the equipment's appearance but, more importantly, damage its internal precision structure, impacting its overall performance. Regarding the testing performance and accuracy, this utility model addresses such issues by installing an I-beam pad. When workers need to move the main housing, they often use a handling handle to accomplish this task. In the initial stage of moving, the worker rotates the handling handle upwards to facilitate subsequent lifting. At this point, the slot on the fixing component plays a crucial role, effectively limiting the rotation angle of the handling handle and ensuring it remains stably in the set position, thus providing a stable and easily positioned moving point for the worker. As the worker begins to lift the main housing, the equipment's significant weight becomes a significant factor. The sides of the main housing bear an upward force through the handling handle. Simultaneously, the main... The center of gravity of the shell is subjected to a downward force of gravity. This combined upward and downward force causes the two side panels of the main shell to tend to rotate around their bottom edges. To counteract this tendency, curved plates play a crucial role. Through their tight support with the top cover, the curved plates provide an outward pulling force to the main shell, effectively preventing the side panels from tilting towards the center. During handling, I-beam pads also play an irreplaceable role. Because only the edges of the I-beam pads curve outward and contact the side panels of the main shell, this design effectively avoids the problem of the main shell bulging outward due to direct contact. Furthermore, the I-beam pads distribute pressure through their large contact area.This further reduces the deformation of the main casing, thus protecting the integrity and performance of the equipment. Notably, to meet the needs of different users and extend the equipment's lifespan, operators can easily replace the handling handle using fixed screws. This design not only improves the user experience but also ensures the equipment maintains better condition and performance over long-term use. Through these ingenious designs and a reasonable structural arrangement, the audio analyzer not only achieves convenient and quick handling but also ensures the stability and safety of the equipment during transport.

[0014] 2. In existing technologies, some audio analysis devices are designed with the chamber plates directly fixed to the inner wall of the main housing. While this design has advantages in certain specific scenarios, it brings many inconveniences during device installation. Because the chamber plates are directly fixed and cannot be moved, this greatly limits the operating space inside the main housing. When installing the device or wiring, workers find the available space extremely limited, making installation exceptionally difficult and requiring significant time and effort. More seriously, this design makes changing the number and position of the chamber plates on the inner wall of the main housing virtually impossible. Once the device's requirements change, or adjustments are needed to adapt to new usage scenarios, workers find they cannot flexibly adjust the chamber plate configuration to meet new needs. This further limits the device's applicability, making it difficult to meet the personalized needs of different users. To address these issues, this utility model solves the problem by using an installation beam, allowing workers to easily adjust the configuration of the chamber plates when organizing audio... The internal structure of the analyzer offers a degree of flexibility. Based on actual conditions, the number of installation beams and bins can be precisely selected to ensure a rational and efficient internal layout. Furthermore, to enhance stability and prevent deformation, additional surface-mounting ramps are installed. These ramps are designed to increase the contact area with the main housing, effectively dispersing the pressure from bins housing heavier modules when the equipment tilts, preventing compression and deformation of the main housing. During installation, the bins are first slid into pre-designed installation grooves. This step not only ensures accurate bin positioning but also facilitates subsequent module installation. Using the installation grooves, the installation position of the bins can be flexibly selected based on the specific location of the modules and the size of the bins. Once the ideal position is determined, bolts are used to firmly fix the bins to the main housing, ensuring that the bins will not shift or fall off due to vibration or movement during operation, thus improving the user experience.

[0015] 3. In existing technologies, when an audio analyzer is accidentally impacted, the end plate of its main housing is often the first to be dented due to external force. This dent not only affects the aesthetics of the equipment but also damages the precision components inside, thus affecting the normal operation and lifespan of the equipment. In another common scenario, when the equipment is lifted by the handle, the side plate of the main housing tends to be squeezed towards the center due to the combined upward pulling force and gravity. This tendency causes the end plate to be subjected to outward tension, resulting in an outward bulge. This bulge also negatively impacts the structural stability of the equipment, causing component deformation and misalignment, and even leading to more serious equipment failures. To address these issues, this invention uses a convex arc plate to solve the problem. This significantly increases the thickness and overall strength of the vulnerable central part of the main housing. Not only can it effectively prevent the main housing from bending due to its own weight or external pressure, but it can also improve the equipment's impact resistance to a certain extent. At the same time, in order to improve the installation accuracy and stability of the internal components, the design team also introduced a toothed plate. This toothed plate is carefully designed to achieve a tighter and more suitable fit with the inner wall of the main housing. This tight fit not only helps to ensure the accurate positioning and stable installation of the internal components, but also disperses external impact forces to a certain extent, reducing the direct impact on the main housing. In addition, in order to further enhance the structural strength of the main housing, especially in key areas such as screw holes, the design team also adopted measures to thicken the screws. By increasing the thickness of the material around the screw holes, the strength of these parts can be significantly improved, ensuring that the connection will not loosen or fail due to fatigue or deformation of the material around the screw holes during long-term use, thereby improving the service life of the equipment.

[0024] 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.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0027] Reference Figure 1-6An audio analyzer assembly structure includes a main housing 1. Grooves 101 are provided on the top of both sides of the main housing 1. A curved plate 103 is fixed to the groove 101. A top cover 102 is fixed to the top of the curved plate 103. I-beam pads 2 are fixed on both sides of the inner wall of the main housing 1. Fixing nails 201 are fixed on the surface of the I-beam pads 2. A fixing element 202 is fixed to one end of the fixing nail 201. A handling handle 203 is rotatably connected to one end of the fixing element 202. A recessed groove 204 is provided on both sides of the main housing 1. A mounting beam 3 is fixed to one side of the I-beam pad 2. A mounting groove 301 is provided on one side of the mounting beam 3. A chamber plate 302 is fixed to the inner wall of the mounting groove 301. A lifting plate 303 is fixed to one end of the chamber plate 302. Some audio analysis devices are designed with the chamber plate 302 directly fixed to the inner wall of the main housing 1. While this design has advantages in certain specific scenarios, it brings many inconveniences during equipment installation. Because the chamber plate 302 is directly fixed and cannot be moved, this greatly limits the operating space inside the main housing 1. During equipment installation or wiring, workers will... The limited available space made equipment installation extremely difficult, requiring significant time and effort to complete. More seriously, this design made it nearly impossible to change the number and position of the inner walls of the main housing 1's chamber plates 302. If equipment requirements changed or needed adjustment for new usage scenarios, staff found they couldn't flexibly adjust the configuration of the chamber plates 302 to adapt to new needs. This further limited the equipment's applicability, making it difficult to meet the personalized needs of different users. The installation of crossbeams 3 solved this problem, providing staff with some flexibility when organizing the internal structure of the audio analyzer. They could precisely select the number of crossbeams 3 and chamber plates 302 based on the actual situation, ensuring a reasonable and efficient internal layout. Furthermore, to enhance equipment stability and prevent deformation, additional faceplates 303 were installed. These faceplates 303 were designed to increase the contact area with the main housing 1, effectively dispersing the pressure generated by the chamber plates 302 with heavier modules when the equipment tilted, preventing compression and deformation of the main housing 1. During the process, the staff will first slide the silo plate 302 into the pre-designed installation groove 301. This step not only ensures the accurate positioning of the silo plate 302, but also facilitates the subsequent module installation. Through the installation groove 301, the staff can flexibly choose the installation position of the silo plate 302 according to the specific position of the module and the size of the silo plate 302. Once the ideal position is determined, the staff will use bolts to firmly fix the silo plate 302 to the main housing 1, ensuring that the silo plate 302 will not shift or fall off due to vibration or movement during the operation of the equipment, thereby improving the user experience.

[0028] A mesh plate 4 is fixed to one end of the main housing 1, a convex arc plate 401 is fixed to one end of the main housing 1, a toothed plate 402 is fixed to one end of the convex arc plate 401, and a thickened screw 403 is fixed to one end of the toothed plate 402. When the audio analyzer is accidentally bumped, the end plate of its main housing 1 is often the first to be impacted and is easily dented due to external force. This dent not only affects the appearance of the equipment but also damages the precision components inside, thus affecting the normal operation and service life of the equipment. In another common scenario, when the operator lifts the equipment using the handle 203, the side plate of the main housing 1 tends to be squeezed towards the center due to the combined effect of upward tension and gravity. This tendency will cause the end plate to be subjected to outward tension to a certain extent, causing the end plate to bulge outward. This bulge will also negatively affect the structural stability of the equipment, causing component deformation and skewing, and even more serious equipment failures. The installation of the convex arc plate 401 solves this problem, achieving a significant increase in stability. By increasing the thickness and overall strength of the vulnerable central section of the main housing 1, this design not only effectively prevents bending of the main housing 1 due to its own weight or external pressure, but also improves the equipment's impact resistance to a certain extent. Simultaneously, to improve the installation accuracy and stability of internal components, the design team introduced a toothed plate 402. This toothed plate 402 is carefully designed to achieve a tighter and more suitable fit with the inner wall of the main housing 1. This tight fit not only helps ensure the accurate positioning and stable installation of internal components, but also disperses external impact forces to a certain extent, reducing the direct impact on the main housing 1. Furthermore, to further enhance the structural strength of the main housing 1, especially in critical areas such as screw holes, the design team also adopted measures to thicken the screws 403. By increasing the thickness of the material around the screw holes, the strength of these areas can be significantly improved, ensuring that the connection will not loosen or fail due to fatigue or deformation of the material around the screw holes during long-term use, thus extending the equipment's service life. The inner wall of the convex arc plate 401 is fixed with reinforcing ribs 404, which improves the strength of the convex arc plate 401 itself, thereby extending the equipment's service life. A support beam 5 is fixed to the top of the inner wall of the main housing 1. This support beam 5 prevents deformation of the side plates of the main housing 1, thereby extending the service life of the equipment. A threaded nail 601 is fixed to the bottom of the main housing 1, and a support leg 6 is fixed to the bottom of the main housing 1 via the threaded nail 601. This support leg 6 prevents the main housing 1 from directly contacting the ground, further extending the service life of the equipment. A fixing plate 7 is fixed to the other end of the main housing 1. This fixing plate 7 prevents deformation of the installation position of the heavier power module, further extending the service life of the equipment.

[0029] The working principle of this utility model is as follows: When workers need to move the main housing 1, they often use the handling handle 203 to accomplish this task. In the initial stage of moving, the workers rotate the handling handle 203 so that it faces upwards to facilitate subsequent lifting operations. At this time, the slot on the fixing part 202 plays a key role. It effectively limits the rotation angle of the handling handle 203, ensuring that the handling handle 203 can stably stay in the set position, thus providing the workers with a stable and easy-to-position moving point. As the workers begin to lift the main housing 1, the large weight of the equipment becomes an unavoidable factor. The two sides of the main housing 1 bear an upward force through the handling handle 203, while at the same time, the center of gravity of the main housing 1 is subjected to a downward gravity. This combined upward and downward force causes the two side plates of the main housing 1 to exhibit a tendency to rotate around the bottom as the axial center. To counteract this trend, the curved edge plate 103 plays a crucial role. Through its tight support with the top cover 102, the curved edge plate 103 provides an outward pulling force to the main housing 1, effectively preventing the side plates of the main housing 1 from tilting towards the center. During handling, the I-beam pad 2 also plays an irreplaceable role. Since only the edge of the I-beam pad 2 bends outward and contacts the side plates of the main housing 1, this design effectively avoids the problem of the main housing 1 bulging outward due to direct contact between the I-beam pad 2 and the main housing 1. Simultaneously, the I-beam pad 2 distributes pressure through its large contact area, further reducing the deformation of the main housing 1, thus protecting the integrity and performance of the equipment. It is worth mentioning that, to meet the needs of different users and extend the service life of the equipment, operators can replace the handling handle 203 at any time using the fixing nails 201.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. 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. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
