Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to an enhanced waterproof outdoor loudspeaker. Background Technology

[0002] Outdoor loudspeakers, as a type of audio playback device professionally designed for outdoor environments, are used in parks, squares, open-air stages, and swimming pools to provide clear, high-quality audio playback services in open areas facing various weather conditions.

[0003] Traditional waterproof loudspeakers mainly consist of a housing, speaker unit, circuit board, and simple sealing gaskets. In use, they are placed in a designated outdoor location, powered on, or connected to a playback device to play audio. Their waterproof sealing structure is relatively simple. However, prolonged exposure to harsh outdoor environments allows moisture to seep into the speaker, corroding the internal electronic components. Current technology has improved this by adding a more complex sealing structure, employing multiple layers of sealing gaskets and sealant. When the loudspeaker operates for extended periods, the internal electronic components generate significant heat. While the added sealing structure effectively prevents moisture ingress, it also hinders heat dissipation. As heat accumulates inside the speaker, the internal temperature rises continuously, and excessively high temperatures can affect the performance stability of the electronic components. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an enhanced waterproof outdoor speaker, which aims to improve the problem that while the newly added sealing structure in the prior art effectively prevents moisture from entering, it also hinders heat dissipation and affects the performance stability of electronic components.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an enhanced waterproof outdoor speaker, including a waterproof box, a speaker fixedly connected to the inner wall of the waterproof box, a mounting groove formed on the front side of the outer wall of the waterproof box, a waterproof sleeve slidably connected to the inner wall of the mounting groove, limit blocks fixedly connected to the top and bottom sides of the waterproof sleeve, slots formed on the left and right sides of the inner wall of the mounting groove, and two limit blocks slidably connected to their corresponding slots, a sealing ring fixedly connected to the rear side of the outer wall of the waterproof box, and a heat dissipation plate threadedly connected to the rear side of the outer wall of the sealing ring. The outer wall of the heat sink has multiple heat dissipation holes, and the inner walls of the multiple heat dissipation holes are fixedly connected to a waterproof membrane. The inner walls of the multiple waterproof membranes are all provided with vent holes. A lifting rod is provided at the bottom of the waterproof box. A quick-connect mechanism is provided between the waterproof box and the lifting rod. The quick-connect mechanism is used to quickly connect the waterproof box and the lifting rod.

The outer walls of the multiple extrusion plates are threadedly connected to the same rotating sleeve. A movable seat is threadedly connected to the bottom of the hollow sleeve.

[0006] As a further description of the above technical solution:

[0007] The quick-connect mechanism includes a first fixing plate, the top of which is fixedly connected to the bottom of the waterproof box. A second fixing plate is fixedly connected to the top of the lifting rod. Each of the four sides of the bottom of the first fixing plate is fixedly connected with a locking block. Each of the four sides of the top of the second fixing plate is provided with an installation groove. The locking block is slidably connected to the installation groove. Each of the four sides of the inner wall of the second fixing plate is provided with an arc-shaped groove. Multiple locking blocks are slidably connected to the corresponding installation grooves.

[0008] As a further description of the above technical solution:

[0009] A water baffle is fixedly connected to the top front side of the outer wall of the waterproof box, and multiple drainage grooves are provided on the top left and right sides of the water baffle.

[0018] As a further description of the above technical solution:

[0019] A shock-absorbing pad is fixedly connected to the bottom of the fixing plate, and multiple locking blocks penetrate the shock-absorbing pad.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, the sliding fit between the waterproof sleeve and the mounting groove, as well as the synergistic effect of the limiting block and the slot, effectively prevents water from seeping in from the front. The threaded connection between the sealing ring and the heat sink plate enhances the rear sealing performance.

The threaded connection between the hollow sleeve and the moving seat facilitates movement and meets the sound and site adaptability requirements of different scenarios.

[0022] In this invention, during installation, by aligning the first and second fixing plates and engaging the locking block with the arc groove, rotating the first fixing plate causes the locking block to slide, thus achieving a secure connection between the waterproof box and the lifting rod. This meets the stable usage requirements of the equipment in different environments. During disassembly, simply rotating the first fixing plate in the opposite direction and lifting it separates the two components. The entire mechanism is easy to operate, greatly improving the efficiency of equipment assembly and disassembly, and providing convenience for equipment installation, maintenance, and site relocation, while saving manpower and time costs.

[0032] 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.

[0033] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an enhanced waterproof outdoor loudspeaker, including a waterproof box 1, which serves as the main protective structure for the entire loudspeaker 3, providing waterproof protection for internal components such as the loudspeaker 3. The loudspeaker 3 is fixedly connected to the inner wall of the waterproof box 1 for playing audio and achieving sound output. A groove 4 is provided on the front side of the outer wall of the waterproof box 1 for installing a waterproof sleeve 5. The waterproof sleeve 5 is slidably connected to the inner wall of the groove 4, preventing moisture from seeping in from the front of the loudspeaker 3 and enhancing waterproof performance. Limiting blocks 6 are fixedly connected to the top and bottom sides of the waterproof sleeve 5. The limiting blocks 6 cooperate with slots 7 to restrict the position of the waterproof sleeve 5 within the groove 4. Slots 7 are provided on the left and right sides of the inner wall of the groove 4. The two limiting blocks 6 are slidably connected to the corresponding slots 7, making the waterproof sleeve 5 more securely installed and easy to disassemble. A sealing ring 8 is fixedly connected to the rear side of the outer wall of the waterproof box 1 to enhance the sealing performance of the rear wall of the waterproof box 1. A heat dissipation plate 9 is threadedly connected to the rear side of the outer wall of the sealing ring 8, providing a channel for internal heat dissipation and solving the heat dissipation problem. The outer wall of the heat dissipation plate 9 has multiple heat dissipation holes 10. The inner wall of each heat dissipation hole 10 is fixedly connected with a waterproof membrane 11, which allows heat to dissipate while preventing external moisture from entering through the heat dissipation holes 10. The inner wall of each waterproof membrane 11 has ventilation holes 12, which are specific channels for heat dissipation, thus achieving a balance between heat dissipation and waterproofing. The bottom of the waterproof box 1 is provided with a lifting rod 13 for adjusting the height of the speaker 3. A quick-connect mechanism 2 is provided between the waterproof box 1 and the lifting rod 13 for quick connection. The bottom of the outer wall of the lifting rod 13 is slidably connected with a hollow sleeve 14, which cooperates with the lifting rod 13 to achieve the height adjustment function. The top of the hollow sleeve 14 is fixedly connected with multiple extrusion plates 15, which are threadedly connected to the rotating sleeve 16 to provide the action point for the rotating sleeve 16. The outer walls of the multiple extrusion plates 15 are threadedly connected to the same rotating sleeve 16. The bottom of the hollow sleeve 14 is threadedly connected with a movable seat 17, which facilitates the movement of the entire device in different positions and enhances the adaptability of the equipment to different outdoor sites.

[0034] Specifically, the waterproof box 1, as the main protective structure, provides protection for the speaker 3. The waterproof sleeve 5 inside the groove 4 on the front side of its outer wall is tightly fitted by the sliding connection between the limiting blocks 6 on the top and bottom sides and the slots 7 on the left and right sides of the inner wall of the groove 4, effectively preventing water from seeping in from the front and preventing water from directly contacting the speaker 3. On the rear wall of the waterproof box 1, the sealing ring 8 is threadedly connected to the heat sink 9, further enhancing the overall sealing performance and preventing water from entering from the rear, ensuring the speaker 3 is in a waterproof environment from all angles. Multiple heat dissipation holes 10 are opened on the heat sink 9, which is key to solving the heat dissipation problem. The waterproof membrane 11 fixed to the inner wall of the heat dissipation holes 10... The vent 12 allows heat to dissipate while preventing external moisture from entering. In this way, the internal heat can be effectively dissipated without affecting the waterproof performance, preventing heat accumulation due to the sealed structure from affecting the performance of electronic components. When the rotating sleeve 16 is rotated, due to the threaded transmission principle, the rotating sleeve 16 moves up and down along the extrusion plate 15, thereby extruding the lifting rod 13 to adjust the height of the speaker 3 to meet the needs of sound propagation range and effect in different scenarios. The movable seat 17 with threaded connection at the bottom of the hollow sleeve 14 makes it easy for the entire speaker 3 to move in different positions, enhancing the adaptability of the equipment to various outdoor venues.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The quick-connect mechanism 2 includes a first fixing plate 201 for connecting the waterproof box 1 and the locking block 203. The top of the first fixing plate 201 is fixedly connected to the bottom of the waterproof box 1. The top of the lifting rod 13 is fixedly connected to a second fixing plate 202. The bottom four sides of the first fixing plate 201 are fixedly connected to locking blocks 203. The top four sides of the second fixing plate 202 are provided with mounting grooves 204. The locking blocks 203 are slidably connected to the mounting grooves 204. Multiple locking blocks 203 are slidably connected to the corresponding mounting grooves 204. The inner wall of the second fixing plate 202 is provided with arc-shaped grooves 205. The locking blocks 203 achieve quick connection and positioning of the waterproof box 1 and the lifting rod 13 by sliding with the mounting grooves 204 and the arc-shaped grooves 205.

[0036] Specifically, during installation, first fix the top of the fixing plate 1 201 to the bottom of the waterproof box 1. Align the locking blocks 203 around the bottom of the fixing plate 1 201 with the mounting grooves 204 around the top of the fixing plate 202. Then, slowly lower the waterproof box 1, and the locking blocks 203 will slide into the mounting grooves 204. Next, rotate the fixing plate 1 201. Since the inner wall of the fixing plate 202 has arc-shaped grooves 205, the locking blocks 203 will slide along a specific trajectory within the arc-shaped grooves 205. During the sliding process, the locking blocks 203 are limited and constrained in the horizontal and vertical directions, thus firmly connecting the waterproof box 1 and the lifting rod 13. During disassembly, rotate the fixing plate 1 201 in the opposite direction, so that the locking blocks 203 slide back to the initial position along the arc-shaped grooves 205. Then lift the fixing plate 1 201 upwards, and the locking blocks 203 will disengage from the mounting grooves 204, thus separating the waterproof box 1 from the lifting rod 13.

[0037] Reference Figure 1 , Figure 2 and Figure 6 A water baffle 18 is fixedly connected to the top front side of the outer wall of the waterproof box 1 to block water flowing down from above. Multiple drainage grooves 19 are provided on the top left and right sides of the water baffle 18 to guide the water flow away quickly and enhance the waterproof effect. Multiple power lights 20 are fixedly connected to the bottom front side of the outer wall of the waterproof box 1 to intuitively display the power level. All power lights 20 are waterproofed. Hidden handles 21 are provided on the left and right sides of the outer wall of the waterproof box 1 for easy gripping and carrying of the speaker 3. The surfaces of the multiple hidden handles 21 are treated with anti-slip treatment.

[0038] Specifically, the water baffle 18 on the top front side of the outer wall of the waterproof box 1 can block water flowing down from above, and the drainage channels 19 on the left and right sides of the top can guide the water flow away quickly, enhancing the waterproof effect. The power indicator 20 on the bottom front side of the outer wall is waterproofed and is used to intuitively display the power level and is not afraid of water immersion. The hidden handles 21 on the left and right sides of the outer wall have a non-slip surface, making it easy for users to hold and move the speaker 3. The hidden design does not affect the overall appearance and waterproof performance.

[0039] Reference Figure 1 , Figure 6 and Figure 7 The outer wall of the rotating sleeve 16 is provided with multiple anti-slip grooves 22. The spacing between adjacent anti-slip grooves 22 is equal, which increases the friction when the hand contacts the rotating sleeve 16, making it convenient for the operator to rotate. Multiple moving wheels 23 are fixedly connected to the bottom of the movable base 17. The surface of the multiple moving wheels 23 is treated with wear resistance, which makes the speaker 3 move more smoothly and adapts to different outdoor sites. The bottom of the fixed plate 1 201 is fixedly connected with a shock-absorbing pad 24. Multiple locking blocks 203 pass through the shock-absorbing pad 24. When connecting the waterproof box 1 and the lifting rod 13, they can buffer vibration and protect the internal components. The locking blocks 203 pass through them without affecting the connection function.

[0040] Specifically, the anti-slip grooves 22 on the outer wall of the rotating sleeve 16 are evenly spaced, which increases the friction when the hand contacts the rotating sleeve 16, making it easy for the operator to rotate it and thus easily adjust the height of the speaker 3. The moving wheels 23 around the bottom of the moving base 17 are wear-resistant, reducing wear and making the speaker 3 move more smoothly and adapt to different outdoor sites. The shock-absorbing pads 24 on the bottom of the fixing plate 1 201 can buffer vibration and protect internal components when connecting the waterproof box 1 and the lifting rod 13. The locking block 203 passes through it without affecting the connection function.

[0041] Working principle: First, regarding waterproofing and heat dissipation, a waterproof sleeve 5 is slidably connected within the groove 4 on the front side of the outer wall of the waterproof box 1. The limiting blocks 6 on the top and bottom sides of the sleeve 5 slide against the slots 7 on the left and right sides of the inner wall of the groove 4, effectively preventing moisture from seeping in from the front of the speaker 3. On the rear wall of the waterproof box 1, a sealing ring 8 is threadedly connected to a heat dissipation plate 9, further enhancing the overall sealing and preventing moisture from entering from the rear. Multiple heat dissipation holes 10 on the heat dissipation plate 9 are a key design feature for solving heat dissipation. A waterproof membrane 11, fixedly connected to the inner wall of the heat dissipation holes 10, allows heat to dissipate through its vent holes 12 while blocking external moisture from entering, thus ensuring waterproofing performance. The problem of poor heat dissipation caused by the sealed structure is solved, avoiding the impact of internal heat accumulation on the performance stability of electronic components. The bottom of the outer wall of the lifting rod 13 is slidably connected to the hollow sleeve 14. Multiple extrusion plates 15 fixed on the top of the hollow sleeve 14 are threadedly connected to the rotating sleeve 16. When the rotating sleeve 16 is rotated, due to the thread action, the rotating sleeve 16 will move up and down along the extrusion plates 15, thereby driving the hollow sleeve 14 to slide relative to the lifting rod 13, realizing the adjustment of the height of the speaker 3 to meet the needs of sound propagation range and effect in different scenarios. The movable seat 17 threaded at the bottom of the hollow sleeve 14 facilitates the movement of the entire device in different positions, enabling the equipment to flexibly adapt to various outdoor venues.

[0042] Furthermore, when installing the waterproof box 1 and the lifting rod, fix the top of the fixing plate 1 201 to the bottom of the waterproof box 1 and align it with the top of the fixing plate 202. At this time, the locking blocks 203 fixedly connected to the bottom of the fixing plate 1 201 are aligned with the corresponding positions opened on the top of the fixing plate 202. Then, slowly lower the waterproof box 1, and the locking blocks 203 enter the arc-shaped grooves 205 opened on the inner wall of the fixing plate 202. Rotate the fixing plate 1 201, causing the locking blocks 203 to slide along a specific trajectory in the arc-shaped grooves 205. As the locking blocks 203 slide in the arc-shaped grooves 205, their positions change. The change causes the locking block 203 to be further constrained in both the horizontal and vertical directions, thus firmly connecting the waterproof box 1 and the lifting rod 13 together, meeting the needs of stable use of the equipment in different environments. When disassembly is required, the fixing plate 201 is rotated in the reverse direction, causing the locking block 203 to slide back to its initial position along the arc groove 205. Then, the fixing plate 201 is lifted upwards, allowing the locking block 203 to disengage from the mounting groove 204, thereby separating the waterproof box 1 from the lifting rod 13. The entire quick-connect mechanism 2 is easy to operate, has a stable connection, and effectively improves the efficiency of equipment assembly and disassembly.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
