Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a structurally stable bass loudspeaker. Background Technology

[0002] The function of a subwoofer is to amplify the low-frequency range, that is, to boost the long-wavelength portion of the audio signal below 100Hz, and even including infrasound. Although humans cannot hear this, it still has an effect. Because ordinary loudspeakers have limited size, they cannot produce low-frequency sounds with longer wavelengths, so a larger subwoofer is needed to generate a powerful low-frequency effect. On the other hand, low-frequency sound waves are the longest and have relatively low energy conversion efficiency, so producing them is also very energy-intensive; that is, to achieve the same output power, a larger input power is required.

[0003] In most existing woofers, the cover and frame are fixed with hot melt adhesive. Over time, the hot melt adhesive is prone to cracking due to vibration, affecting the overall structural stability. Summary of the Invention

[0004] In view of the above-mentioned technical problems in the existing technology, the present invention provides a woofer with a stable structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A structurally stable woofer is provided, including a frame, a diaphragm assembly inside the frame, a magnetic circuit assembly at the lower end of the frame, and a cover at the upper end of the diaphragm assembly. Threaded holes are provided on both the cover and the outer wall of the frame, with multiple threaded holes arranged in a circumferential pattern. Connecting screws are installed inside each threaded hole. A cylindrical body is also provided at the bottom of the frame, with placement grooves inside each groove. Connecting nuts are installed inside the placement grooves, and connecting screws are threadedly connected to the connecting nuts. Insertion holes are also provided on the outer walls of the cylindrical body and the connecting screws, with pins movably installed inside the insertion holes. A fastening ring is provided on the outer wall of the cylindrical body, threadedly installed with the cylindrical body. The two ends of the pin abut against the inner wall of the fastening ring.

[0007] Preferably, the cover is a ring structure, with a dust filter screen on the outer side of the cover. A connecting ring is fixedly provided at the edge of the dust filter screen, and connecting holes are provided on the outer wall of the connecting ring. Multiple connecting holes are provided corresponding to threaded holes, and the upper end of the connecting screw is located inside the connecting hole.

[0008] Preferably, the upper end face of the connecting screws is provided with a cross groove.

[0009] Preferably, an external connecting block is fixed on the outer wall of the basin frame, and multiple external connecting blocks have external connecting holes on their outer walls, with lubricating screws inside the external connecting holes.

[0010] Preferably, the lubricating screw has a cavity inside, and the cavity has multiple oil leakage holes that are evenly distributed. One end of the lubricating screw has an oil injection hole, and the oil injection hole has a plug inside. The outer wall of the plug is threaded to the oil injection hole.

[0011] Preferably, the outer wall of the fastening ring is provided with anti-slip texture, which is distributed along the circumference of the fastening ring.

[0012] Preferably, the inner wall of the placement groove is hexagonal in shape, and the outer wall of the connecting nut fits tightly against the inner wall of the placement groove.

[0013] The beneficial effects of this utility model are:

[0014] This utility model discloses a structurally stable woofer. By incorporating a cover, threaded holes, connecting screws, and a pin, the user can screw the connecting screw into the threaded hole to secure the cover and frame.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] This embodiment provides a structurally stable subwoofer, such as... Figures 1 to 6 As shown, it includes a basin frame 1, a diaphragm assembly 2 is provided inside the basin frame 1, a magnetic circuit assembly 3 is provided at the lower end of the basin frame 1, and a cover 4 is provided at the upper end of the diaphragm assembly 2. The cover 4 is a ring structure.

[0024] Both the cover 4 and the basin stand 1 have threaded holes 5 on their outer walls. Multiple threaded holes 5 are arranged in a circular pattern, and each threaded hole 5 contains a connecting screw 6. A cylindrical body 7 is fixed to the bottom of the basin stand 1, and each cylindrical body 7 has a placement groove 8 inside. A connecting nut 9 is placed inside each placement groove 8. The lower end of the connecting screw 6 is threadedly connected to the connecting nut 9. In use, the connecting screw 6 is screwed into the threaded hole 5 to fix the cover 4 and the basin stand 1. Simultaneously, the bottom of the connecting screw 6 also enters the connecting nut 9, achieving a locking effect through the threads between the two.

[0025] In addition, the inner wall of the placement groove 8 is hexagonal in shape, and the outer wall of the connecting nut 9 fits tightly against the inner wall of the placement groove 8. This shape matching restricts the rotation of the connecting nut 9, preventing it from rotating synchronously with the connecting screw 6 and ensuring a secure fit during installation.

[0026] Furthermore, coaxial insertion holes 10 are correspondingly provided on the outer walls of the cylinder 7 and the connecting screw 6, and a pin 11 is movably inserted into the insertion hole 10. When the pin 11 is simultaneously inserted into the insertion holes 10 of both the cylinder 7 and the connecting screw 6, they form a positioning fit. In addition, a fastening ring 12 is provided on the outer wall of the cylinder 7, and the fastening ring 12 and the cylinder 7 are detachably connected through a threaded structure. Specifically, the pin 11 is first inserted into the insertion hole 10 to fix the relative position of the cylinder 7 and the connecting screw 6, and then the fastening ring 12 is rotated to move axially along the outer wall of the cylinder 7. When both ends of the pin 11 abut against the inner wall of the fastening ring 12, the fastening ring 12 is installed in place. At this time, the fastening ring 12 not only forms an axial limit on the pin 11 from the outside to prevent it from accidentally coming out, but also further compacts the connection between the cylinder 7 and the connecting screw 6 through the thread preload. This dual fixing mechanism gives the connection interface between the cover 4 and the frame 1 stronger vibration resistance, effectively avoiding the problem of opening or loosening caused by vibration during use, thereby ensuring the long-term stability of the overall structure of the subwoofer.

[0027] In addition, anti-slip textures are provided on the outer wall of the fastening ring 12. The anti-slip textures are evenly distributed around the circumference of the fastening ring 12. This design increases the coefficient of friction between the fingers and the surface of the fastening ring, allowing the operator to obtain a more stable grip when rotating the fastening ring. Even when wearing gloves or with wet hands, the tightening or loosening of the fastening ring can be easily completed.

[0028] Furthermore, a dust filter 13 is provided on the outer side of the cover 4, and a connecting ring 14 is fixedly provided at the edge of the dust filter 13. Connecting holes 15 are provided on the outer wall of the connecting ring 14, with each connecting hole 15 corresponding to a threaded hole 5. When the connecting screw 6 and the connecting nut 9 are threaded together, the connecting ring 14 of the dust filter 13 fits snugly against the cover 4, and the upper end of the connecting screw 6 is located inside the connecting hole 15. By providing the dust filter 13, the front end of the subwoofer can be protected and dust filtered, reducing dust ingress and extending the speaker's lifespan.

[0029] In addition, to facilitate the threaded connection between the connecting screw 6 and the connecting nut 9, a cross groove 16 is provided on the top of the connecting screw 6. The cross groove 16 is compatible with both common Phillips screwdriver bits and Torx screwdriver bits, making it easy to use general tools for quick disassembly and assembly.

[0030] Furthermore, an external connecting block 17 is fixedly installed on the outer wall of the speaker frame 1. Multiple external connecting blocks 17 are provided, each with an external connecting hole 18 on its outer wall. Each external connecting hole 18 has a lubrication screw 19 inside. The lubrication screw 19 has a cavity 20 inside, and multiple oil leakage holes 21 are evenly distributed within the cavity 20. One end of the lubrication screw 19 has an oil injection hole 22, and a plug 23 is installed inside the oil injection hole 22. The outer wall of the plug 23 is threadedly connected to the oil injection hole 22. The speaker is fixed to external equipment using the lubrication screws 19. The plug 23 can also be periodically unscrewed to inject lubricating oil into the cavity 20 through the oil injection hole 22. The lubricating oil will then flow out from the oil leakage hole 21, lubricating the connection point of the lubrication screw 19 and preventing corrosion.
