Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, specifically to a subwoofer that is easy to install. Background Technology

[0002] Subwoofers are mainly categorized by size into large, medium, and small. Their primary function is to reproduce the low-frequency range (typically 20-200Hz) of audio signals, enhancing the richness and impact of the sound. This allows listeners to clearly perceive low-frequency details such as bass, drum beats, or explosions in film sound effects, thus improving auditory immersion. Internally, a cone diaphragm, voice coil, and magnet work together to generate bass. Specifically, the magnet provides a stable magnetic field, and when an audio current is passed through the voice coil, it experiences a force in the magnetic field, causing the cone diaphragm to vibrate. The diaphragm then pushes the surrounding... Air generates low-frequency sound waves, while the centering support ensures the voice coil moves axially to avoid displacement, and the surround assists the diaphragm vibration and limits displacement, together ensuring stable low-frequency sound output; at the same time, most woofers need to be fixed to the wall, the core of which is to use the wall to enhance low-frequency sound effects and ensure stable operation. Specifically, the wall can act as an "acoustic reflector," allowing the low-frequency sound waves emitted by the speaker to be reflected and superimposed after being reflected by the wall, reducing the dispersion and loss of low-frequency signals, improving the fullness and propagation distance of the sound, and avoiding weak bass caused by sound wave diffusion; Currently, most small subwoofers are typically connected to the wall via brackets and bolts, which is a rather inconvenient installation method. To address this issue, existing technologies mostly use pressure-sensitive adhesive to bond the small subwoofer to the wall, greatly improving installation convenience. However, this method suffers from poor wall surface compatibility: if the wall is not perfectly flat, such as having slight bumps, the adhesive layer may not be firmly fixed to the mounting surface. This can result in slight speaker wobbling (causing resonance noise when playing low frequencies) or even complete detachment and damage. Therefore, we propose a subwoofer that is easy to install to solve the problems encountered by existing technologies. Utility Model Content

[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 Figures 1 to 5 As shown, a woofer that is easy to install includes a speaker body 1. An adhesive 3 is also provided on the rear side of the speaker body 1. The adhesive 3 includes an aluminum plate 31 that is hung on the speaker body 1. At least six elastic acrylic pressure-sensitive adhesives 34 are arranged in a ring around the axis of the aluminum plate 31 on the rear side. The six flexible acrylic pressure-sensitive adhesives 34 adapt to uneven walls.

[0020] Specifically, Figure 3 In the middle, an aluminum frame 32 is fixed to the rear side of the speaker body 1 by bolts, and the aluminum frame 32 is arranged in an S-shape; The bolted connection ensures the fixing strength between the aluminum frame 32 and the speaker body 1, preventing loosening during installation or use. The S-shaped structure can adapt to the spatial layout of the rear side of the speaker body 1, avoiding interference with other components. On the other hand, it can optimize the force angle when hanging, making the speaker body 1 more stable after hanging and less prone to tilting due to its own weight.

[0021] Specifically, Figure 4 In the middle, a slot 36 is provided on the front side of the aluminum plate 31, and the lower end of the aluminum frame 32 is inserted into the slot 36; The slot 36 provides a precise positioning and mounting position for the aluminum frame 32, allowing the connection between the aluminum frame 32 and the aluminum plate 31 to be quick and easy without complicated alignment operations. At the same time, the structure of the slot 36 can limit the horizontal displacement of the aluminum frame 32, preventing the speaker body 1 from wobbling left and right after being hung.

[0022] Specifically, Figure 5 In the middle, at least six pins 37 are arranged in a ring around the axis of the aluminum disk 31. Each pin 37 has a connecting plate integrally provided at one end, and the back side of the connecting plate is bonded with acrylic pressure-sensitive adhesive 34. The six pins 37 arranged in a ring allow the acrylic pressure-sensitive adhesive 34 to be evenly distributed in the rear area of ​​the aluminum disc 31. The pins 37 and the connecting plate are integrally formed, which can improve the structural strength and prevent the connecting plate from falling off. The connecting plate provides a stable adhesive base for the acrylic pressure-sensitive adhesive 34, preventing insufficient bonding area caused by the adhesive layer being directly attached to the pins 37. It should be noted that the front side of the acrylic pressure-sensitive adhesive 34 is not attached to the rear side of the aluminum disc 31.

[0023] Specifically, Figure 5 In the middle, each pin 37 is surrounded by a spring 38. One end of the spring 38 is welded to the pulling end of the pin 37, and the other end of the spring 38 is welded to the front side of the aluminum disc 31. The elastic properties of spring 38 can drive pin 37 to extend and retract flexibly. When there are slight protrusions on the wall, pin 37 at the corresponding position will compress spring 38, allowing acrylic pressure-sensitive adhesive 34 to still adhere tightly to the wall and achieve self-adjustment. Welded connection can ensure the firmness of the connection between spring 38, pin 37, and aluminum disc 31, and prevent spring 38 from falling off and affecting the elastic adjustment function.

[0024] Specifically, Figure 5 and Figure 1 In the middle, the pull end of the pin 37 is provided with a locking screw 35, one end of the locking screw 35 is integrally provided with a rubber pad 33 and the rear side of the rubber pad 33 is pressed against the front side of the aluminum plate 31. The rear side of the speaker body 1 is provided with a threaded rod 2, and one end of the threaded rod 2 is attached with a rubber block 4 for pressing against the wall. The locking screw 35 is connected to the pin 37 via threads. When rotated, it pushes the rubber pad 33 against the aluminum disc 31. The rubber pad 33 increases the friction with the aluminum disc 31, improving the locking effect and preventing scratches caused by direct metal contact. The threaded rod 2 can adjust the extension length via threads, allowing the rubber block 4 to press tightly against the wall, further limiting the displacement of the speaker body 1 and reducing resonance when playing low frequencies. The rubber block 4 can buffer the collision between the speaker and the wall, while increasing friction and improving the reinforcement effect.

[0025] Specifically, Figure 4 In the middle, a gap 39 is provided between two adjacent acrylic pressure-sensitive adhesives; The gap 39 allows air trapped between the acrylic pressure-sensitive adhesive 34 and the wall surface to escape when the adhesive layer is applied to the wall, preventing air bubbles from forming and causing the adhesive layer to not adhere tightly. At the same time, when there are small protrusions on the wall surface, the protrusions can be accommodated in the gap 39, preventing the protrusions from squeezing the adhesive layer and causing it to deform or fall off, further improving the adaptability to uneven wall surfaces.

[0026] Working principle: First, the aluminum plate 31 is initially attached to the preset position on the wall, and the acrylic pressure-sensitive adhesive 34 is initially fixed to the wall surface; then, the pin 37 is pushed to compress the spring 38, so that each elastic acrylic pressure-sensitive adhesive 34 is attached to the wall surface, and the adhesive is pressed tightly according to the slight protrusions on the wall surface. The gap 39 between adjacent acrylic pressure-sensitive adhesives 34 is used to expel the air between the adhesive layer and the wall surface. Then, rotate the locking screw 35 to press the rubber pad 33 against the front side of the aluminum disc 31, which can limit the aluminum disc 31 and prevent the aluminum disc 31 from sliding outward too much on the pin 37. Next, the aluminum frame 32 is fixed to the rear side of the speaker body 1 with bolts, and then the lower end of the aluminum frame 32 is inserted into the slot 36 of the aluminum plate 31 to complete the mounting. Finally, the threaded rod 2 on the rear side of the speaker body 1 is rotated to make the rubber block 4 press against the wall for further reinforcement.
