Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to an easy-to-install speaker dustproof mesh structure. Background Technology

[0002] During daily use and long-term storage of speaker equipment, dust protection is a key factor in ensuring its stable performance and lifespan. The core components inside the speaker, such as the speaker unit and circuit board, are extremely sensitive to dust. If dust accumulates for a long time, it will block the gaps in the speaker's voice coil and heat dissipation holes, causing the voice coil vibration to be hindered and the heat dissipation efficiency to decrease, which will lead to sound quality distortion and volume attenuation. In severe cases, it may even cause the speaker to burn out or the circuit board to short-circuit. On the other hand, the moisture or corrosive particles mixed in the dust will also accelerate the oxidation and corrosion of the metal parts inside the speaker, shortening the overall lifespan of the equipment.

[0003] Existing speaker dustproof meshes are generally designed with an arc-shaped surface. The mesh structure of the dustproof mesh makes it easy to deform. Deformed dustproof meshes are not only unsightly, but their folds also easily lead to dust accumulation, resulting in poor dustproof performance. An existing patent (publication number: CN222301931U) discloses a dustproof mesh for a loudspeaker. By setting the elastic locking block, the limiting post is pressed into the limiting hole using the elastic locking block to restore elastic deformation. This allows the dustproof component to be quickly installed on the loudspeaker. By placing the support member at the front end, the dustproof mesh can be prevented from contacting the outside environment, thus preventing deformation of the dustproof mesh due to external forces. Furthermore, when the user rotates the support member, the scraper can scrape off the dust accumulated on the dustproof mesh. Compared to the prior art, its structure is simpler, its operation is more convenient, and it can also perform preliminary cleaning of the dustproof mesh, avoiding frequent washing or replacement of the dustproof mesh.

[0004] To address the aforementioned issues, existing patents offer solutions. However, existing easy-to-install speaker dustproof mesh structures typically use fixed-size frames. During installation, a frame that perfectly matches the speaker's sound outlet size must be selected. If the size is incompatible, it cannot be adapted, making it inconvenient for users to reuse. Furthermore, the dustproof structure is usually connected to the speaker housing using screws, which makes it difficult for users to quickly install and maintain the dustproof structure. Each cleaning or maintenance requires a significant amount of time, thus reducing efficiency.

[0005] To address this, an easy-to-install speaker dustproof mesh structure is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an easy-to-install speaker dustproof mesh structure, which can solve the problems of existing easy-to-install speaker dustproof mesh structures. These structures are usually used with fixed-size frames, and during installation, a frame that perfectly matches the size of the speaker's sound outlet must be selected. If the size does not match, the structure cannot be adapted, which is not convenient for users to use flexibly. Moreover, the dustproof structure is usually connected to the speaker shell by screws, which is not convenient for users to quickly complete the installation and maintenance of the dustproof structure. Each cleaning or maintenance requires a lot of time, thus reducing the efficiency of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install speaker dustproof mesh structure, comprising a speaker shell, a dustproof frame fixedly connected to the front side of the speaker shell, a dustproof mesh disposed inside the dustproof frame, an adjustable frame assembly disposed outside the dustproof mesh, a quick-connect assembly disposed at the bottom of the dustproof mesh, the adjustable frame assembly comprising a fixed frame slidably connected inside the dustproof frame, adjustable support plates slidably connected to both sides inside the fixed frame, a clamping plate fixedly connected to the outside of the adjustable support plate, the clamping plate being located outside the dustproof mesh, a bidirectional screw threadedly connected to the inner side of the adjustable support plate, an adjusting knob fixedly connected to the outside of the bidirectional screw, and a limit guide rod slidably connected to the inner side of the adjustable support plate.

[0008] Preferably, the quick-connect assembly includes a connector fixedly connected to the outside of the dustproof frame, and an abutment spring is fixedly connected inside the connector.

[0009] Preferably, an abutment plate is fixedly connected to the outer side of the abutment spring, a connecting rod is snapped into the inner side of the abutment plate, and a support rod is fixedly connected to the bottom of the connecting rod.

[0010] Preferably, a fixing rod is slidably connected to the outer side of the connecting seat, and the fixing rod is engaged with the connecting support rod.

[0011] Preferably, a dustproof base is fixedly connected to the bottom of the support rod, and a handle rod is fixedly connected to the outside of the dustproof base.

[0012] Preferably, a control panel is provided on the top of the speaker housing, and a data cable port is provided on the top of the control panel.

[0013] Preferably, a caster wheel is fixedly connected to the rear side of the bottom of the speaker housing, and a support leg is fixedly connected to the front side of the bottom of the speaker housing.

[0014] Preferably, a horizontal plate is fixedly connected to the rear side of the speaker housing, and a movable push rod is fixedly connected to the outer side of the horizontal plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application achieves the effect of adapting, fixing and firmly clamping the dustproof net through the adjustable frame component, improving the installation adaptability, fixing stability and operation convenience of the dustproof net. Compared with the traditional speaker dustproof net structure, it can achieve the functions of initial positioning by cooperating with the fixed frame and the dustproof frame, adjusting the spacing of the adjustment support plate and clamping plate by the bidirectional screw to adapt to different sizes of dustproof nets, and ensuring the sliding stability of the adjustment support plate by the limit guide rod. It solves the problems of poor size adaptability of dustproof nets in traditional equipment, installation requires tools and operation is complicated, and gaps are easily generated due to unstable clamping after fixing, resulting in a decrease in dustproof effect. 2. This application achieves the effect of quick disassembly and assembly, and stable connection between the dustproof base and the dustproof frame through the quick connection component, which improves the installation efficiency, connection stability and maintenance convenience of the dustproof base. Compared with the traditional speaker dustproof mesh structure, it can achieve the function of forming an initial elastic snap-fit ​​of the connecting rod through the cooperation of the connecting seat, the anti-spring and the anti-plate, the secondary locking of the connecting rod by the fixing rod, and the function of the support rod driving the dustproof base to cover the gap at the bottom of the speaker shell. It solves the problems of cumbersome disassembly and assembly of the dustproof structure at the bottom of the speaker in traditional equipment, easy loosening of the connection due to external force leading to dust entering the interior, and time-consuming disassembly during maintenance affecting the efficiency of use.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 The present invention provides the following technical solution: An easy-to-install speaker dustproof mesh structure includes a speaker housing 1, a dustproof frame 2 fixedly connected to the front of the speaker housing 1, a dustproof mesh 3 disposed inside the dustproof frame 2, an adjustable frame assembly 4 disposed outside the dustproof mesh 3, and a quick-connect assembly 5 disposed at the bottom of the dustproof mesh 3. The adjustable frame assembly 4 includes a fixed frame 401 slidably connected inside the dustproof frame 2, adjustable support plates 402 slidably connected to both sides inside the fixed frame 401, a clamping plate 403 fixedly connected to the outside of the adjustable support plate 402, the clamping plate 403 being located outside the dustproof mesh 3, a bidirectional screw 404 threadedly connected to the inside of the adjustable support plate 402, an adjusting knob 405 fixedly connected to the outside of the bidirectional screw 404, and a limit guide rod 406 slidably connected to the inside of the adjustable support plate 402.

[0020] In this embodiment: By rotating the adjustment knob 405 on the outside of the fixed frame 401, the adjustment knob 405 will drive the bidirectional screw 404 fixed on the inside to rotate synchronously. Since the bidirectional screw 404 is threadedly connected to the adjustment support plates 402 on both sides, and the adjustment support plates 402 are slidably engaged with the fixed frame 401, when the bidirectional screw 404 rotates, it will drive the adjustment support plates 402 on both sides to slide in opposite directions along the inside of the fixed frame 401, thereby driving the clamping plate 403 on the outside of the adjustment support plate 402 to move synchronously. When the clamping plate 403 moves to the position where it is in contact with the dustproof net... When the outer edges of the dustproof net 3 are in close contact, stop rotating the adjustment knob 405. At this time, the clamping plates 403 on both sides will form a stable clamp on the dustproof net 3. At the same time, the limiting guide rod 406, which is slidably connected to the inner side of the adjustment support plate 402, will limit the rotation trend of the adjustment support plate 402, ensuring that the adjustment support plate 402 slides only in a straight line. This avoids the adjustment support plate 402 from shifting during the clamping process, which would cause uneven force on the dustproof net 3. This is to adapt to dustproof nets 3 of different sizes, and the clamping stability is strong. It can effectively avoid gaps between the dustproof net 3 and the dustproof frame 2, ensuring the dustproof effect.

[0021] Specifically, such as Figure 5 As shown, the quick-connect assembly 5 includes a connector 501 fixedly connected to the outside of the dustproof frame 2, and an abutment spring 502 is fixedly connected inside the connector 501.

[0022] Specifically, such as Figure 5As shown, an abutment plate 503 is fixedly connected to the outer side of the abutment spring 502, a connecting rod 504 is snapped into the inner side of the abutment plate 503, and a support rod 505 is fixedly connected to the bottom of the connecting rod 504.

[0023] Specifically, such as Figure 5 As shown, a fixing rod 506 is slidably connected to the outer side of the connecting seat 501, and the fixing rod 506 is engaged with the connecting support rod 504.

[0024] In this embodiment: When installing the connecting structure corresponding to the dustproof base 6, the operator aligns the connecting rod 504 with the opening of the connecting seat 501 and pushes the connecting rod 504 into the connecting seat 501. The connecting rod 504 will press the abutment plate 503 inside the connecting seat 501, causing the abutment plate 503 to compress the abutment spring 502 fixed on its inner side. When the connecting rod 504 is fully inserted into the inner side of the abutment plate 503, the abutment spring 502 will release its elastic force, pushing the abutment plate 503 tightly against the outer side of the connecting rod 504, forming an initial elastic engagement of the connecting rod 504. Subsequently, the operator slides the fixing rod 506 along the outer side of the connecting seat 501 to fix the connection. One end of the locking rod 506 is inserted into the corresponding slot of the connecting rod 504, forming a secondary lock on the connecting rod 504 to prevent it from detaching from the connecting seat 501 during use. When disassembly is required, first slide the locking rod 506 in the opposite direction to disengage it from the connecting rod 504, then pull the connecting rod 504 outward to overcome the elastic force of the resisting spring 502, and the connecting rod 504 can be removed from the resisting plate 503. This achieves quick disassembly and assembly of the connecting rod 504 and the connecting seat 501, while ensuring a stable connection and preventing the connection from loosening due to external force or vibration after long-term use. This also ensures that the dustproof base 6 can continuously cover the gap at the bottom of the speaker.

[0025] Specifically, such as Figure 6 As shown, a dustproof base 6 is fixedly connected to the bottom of the support rod 505, and a handle rod 7 is fixedly connected to the outside of the dustproof base 6.

[0026] Specifically, such as Figure 2 As shown, a control panel 8 is provided on the top of the speaker housing 1, and a data cable port 9 is provided on the top of the control panel 8.

[0027] In this embodiment: By setting a dustproof base 6 and a handle 7, when installing the dustproof base 6, the operator can directly lift the dustproof base 6 by holding the handle 7 on the outside of the dustproof base 6. At this time, the dustproof base 6 will drive the bottom fixed support rod 505 to move synchronously, thereby aligning the connecting support rod 504 at the top of the support rod 505 with the abutting support plate 503 inside the connecting seat 501, so that the connecting support rod 504 can be quickly snapped into the inner side of the abutting support plate 503 to complete the positioning. By setting a control panel 8 and a data cable port 9, during the overall use of the speaker, when it is necessary to adjust the volume of the speaker or switch the playback mode, the operator can directly operate the buttons on the control panel 8 on the top of the speaker housing 1. The instructions are transmitted to the internal components of the speaker through the control panel 8 to realize real-time control of the speaker function. When it is necessary to connect the speaker to an external device to transmit audio data, or when it is necessary to supplement the power supply to the speaker, the connector of the corresponding data cable can be inserted into the data cable port 9 on the top of the control panel 8 to establish a connection channel between the speaker and the external device.

[0028] Specifically, such as Figure 1 As shown, a caster wheel 10 is fixedly connected to the rear side of the bottom of the speaker housing 1, and a support leg 11 is fixedly connected to the front side of the bottom of the speaker housing 1.

[0029] Specifically, such as Figure 2 As shown, a horizontal plate 12 is fixedly connected to the rear side of the speaker housing 1, and a movable push rod 13 is fixedly connected to the outer side of the horizontal plate 12.

[0030] In this embodiment: By setting the moving wheels 10 and the support legs 11, when it is necessary to adjust the placement of the speaker, since the moving wheels 10 are fixed on the rear side of the bottom of the speaker housing 1, the operator only needs to apply a horizontal pushing force to the speaker, and the moving wheels 10 will roll along the ground, driving the speaker to move smoothly as a whole. The position adjustment can be achieved without carrying it. When the speaker moves to the target position, the support legs 11 on the front side of the bottom of the speaker housing 1 will directly contact the ground. At this time, the support legs 11 will support the speaker housing 1 with their own structural strength, and together with the moving wheels 10, they will restrict the displacement of the speaker and prevent the speaker from sliding due to accidental collisions or slight tilting of the ground during use. By setting the horizontal plate 12 and the moving push rod 13, when pushing the speaker to move its position, the operator can hold the moving push rod 13 on the outer side of the horizontal plate 12 on the rear side of the speaker housing 1 and apply a horizontal pushing force to the moving push rod 13. At this time, the horizontal plate 12 will evenly transmit the pushing force to the speaker housing 1, and then cooperate with the moving wheels 10 at the bottom of the speaker to achieve rolling movement.

[0031] Working principle: When using this speaker dustproof mesh structure, the dustproof mesh 3 is first adjusted for fixation. The fixing frame 401, which is compatible with the dustproof frame 2, can move inside the dustproof frame 2. By rotating the adjustment knob 405, the bidirectional screw 404, which is threadedly connected to the adjustment support plate 402, is rotated. Since the adjustment support plate 402 is slidably engaged with the fixing frame 401 and a limiting guide rod 406 passes through its inner side, the limiting guide rod 406 can restrict the adjustment support plate 402 from rotating with the bidirectional screw 404 and only slide stably along the inside of the fixing frame 401. This allows the outer side of the adjustment support plate 402 to be connected to... The clamping plates 403 move synchronously. By adjusting the distance between the clamping plates 403 on both sides, the dustproof mesh 3 can be securely clamped inside the dustproof frame 2, achieving adaptation and fixation for dustproof meshes 3 of different sizes. This ensures that the dustproof mesh 3 fits the dustproof frame 2 to prevent dust from entering the speaker housing 1. Next, the dustproof base 6 is installed. The connecting seat 501 fixed on the outside of the dustproof frame 2 is equipped with an anti-collision spring 502. The anti-collision spring 502 always applies an elastic force to the anti-collision support plate 503 connected to its outside. After the connecting support rod 504 is inserted into the inside of the anti-collision support plate 503, the connecting support rod... The support rod 505 connected to the bottom of 504 can move the dustproof base 6 to the bottom of the speaker housing 1. At this time, the fixing rod 506 on the outside of the sliding connector 501 is engaged with the connecting rod 504, thus firmly restricting the connecting rod 504 within the connector 501. The dustproof base 6 is then fixed to cover the gap at the bottom of the speaker housing 1, further improving the dustproof effect. If the dustproof base 6 needs to be removed, simply slide the fixing rod 506 in the opposite direction to disengage it from the connecting rod 504, and then pull out the connecting rod 504 against the elastic force of the spring 502. With lever 504, the dustproof base 6 can be removed for cleaning or maintenance. In addition, the control panel 8 on the top of the speaker housing 1 allows users to operate the speaker functions. The data cable port 9 can be used to connect external devices for data transmission or power supply. When moving the speaker, the push rod 13 on the back of the speaker housing 1 can be used to easily push the speaker with the bottom caster 10. After moving to the target position, the bottom support leg 11 can provide stable support for the speaker and prevent it from sliding. The pull rod 7 on the outside of the dustproof base 6 makes it easy for users to lift the dustproof base 6, improving the overall ease of use.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
