Description

Technical Field

[0001] This utility model relates to the field of architectural acoustics, and in particular to a hidden low-frequency trap. Background Technology

[0002] In interior acoustic design, low-frequency sound absorption has always been an important research area. Because low-frequency sound waves have longer wavelengths, they easily form standing waves at room corners and boundaries, affecting the uniform propagation of sound and leading to problems such as low-frequency muddiness and increased reverberation. To improve the indoor acoustic environment, low-frequency traps are typically placed in key locations such as corners to effectively absorb low-frequency sound waves and reduce the generation of standing waves.

[0003] Currently, most low-frequency traps on the market are installed in a fixed manner, that is, placed directly in a corner of the room or fixedly mounted on the wall. While this design can improve the low-frequency absorption effect to some extent, it also has the following problems:

[0004] Space occupation: Traditional low-frequency traps are usually large sound-absorbing structures, which will take up a certain amount of space when placed directly in the corner, affecting the overall layout and aesthetics of the room.

[0005] Not easy to hide: Since low-frequency traps are usually made of sound-absorbing materials, their appearance is difficult to blend with the interior decoration style, and long-term exposure may affect the overall visual effect of the room.

[0006] Inconvenient maintenance: Low-frequency traps are exposed to the air and are prone to dust accumulation. After long-term use, their sound absorption performance will be affected, and cleaning and maintenance are relatively troublesome. Utility Model Content

[0007] This invention relates to a hidden low-frequency trap to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a hidden low-frequency trap, including a first wall and a second wall, the first wall and the second wall forming a corner; a mounting groove, disposed near the corner, for accommodating the low-frequency trap; the low-frequency trap, rotatably disposed within the mounting groove; and a rotating component for connecting the mounting groove and the low-frequency trap, enabling the low-frequency trap to switch between a hidden state and a usable state around the rotating component.

[0009] Preferably, the rotating component includes: a rotating rod for rotatably connecting the low-frequency trap to the mounting slot; an upper locking block fixedly connected to the bottom of the mounting slot; a lower locking block fixedly connected to the low-frequency trap; a spring disposed between the upper and lower locking blocks to separate them; circumferential locking teeth respectively disposed on the opposing surfaces of the upper and lower locking blocks; and a fixing screw fixed to the end of the rotating rod, rotating the fixing screw to bring the lower and upper locking blocks closer together.

[0010] Preferably, a groove is formed on one side of the low-frequency trap.

[0011] Preferably, the mounting groove is provided with protrusions that correspond one-to-one with the openings on the low-frequency trap.

[0012] Preferably, the protrusion is further provided with a chamfer.

[0013] Preferably, the low-frequency trap contact angle is chamfered.

[0014] Preferably, one inner wall of the mounting groove has a chamfer.

[0015] Preferably, the low-frequency trap is filled with a porous sound-absorbing material to improve the absorption of low-frequency noise.

[0016] Through the above technical solutions

[0017] The beneficial effects of this utility model are as follows:

[0018] The concealed design maximizes space utilization. The low-frequency trap is completely hidden within a mounting slot in the corner of the wall, without affecting the overall layout or usable space of the room, avoiding the problem of traditional low-frequency traps occupying a corner.

[0019] Aesthetically pleasing and adaptable to various decorating styles. Because the low-frequency trap is concealed within the installation groove when not in use, it avoids the visual impact of exposed sound-absorbing materials, allowing it to coordinate and unify with the interior design style and enhance the overall aesthetics.

[0020] 3. Dustproof protection and extended service life. When concealed, the sound-absorbing surface of the low-frequency trap fits against the bottom of the mounting groove, and the protrusions in the mounting groove seal the openings on the low-frequency trap, effectively preventing dust from entering. This reduces performance degradation caused by dust accumulation, lowers maintenance costs, and extends service life. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] Please see Figure 1 and Figure 5 A concealed low-frequency trap includes a first wall 100 and a second wall 101, the first wall 100 and the second wall 101 forming a corner 102; a mounting groove 103, disposed near the corner 102, for accommodating a low-frequency trap 104; the low-frequency trap 104, rotatably disposed within the mounting groove 103; and a rotating member 105 for connecting the mounting groove 103 and the low-frequency trap 104, enabling the low-frequency trap 104 to switch between a concealed state and a usable state around the rotating member 105. In this embodiment, when concealed, the low-frequency trap 104 is housed within the mounting groove 103; when in use, the low-frequency trap 104 rotates out around the rotating member 105 and is positioned in the angle between the first wall 100 and the second wall 101; when concealed, the sound-absorbing surface of the low-frequency trap 104 is attached to the bottom of the mounting groove 103 to reduce dust from entering the interior of the low-frequency trap 104; when in use, the low-frequency trap 104 rotates out around the rotating member 105, with its sound-absorbing surface facing the angle formed by the first wall 100 and the second wall 101.

[0034] Furthermore, the rotating component 105 includes: a rotating rod 105a, an upper locking block 105b, a lower locking block 105c, a spring 105d, circumferential locking teeth 105e, and a fixing screw 105f. The rotating rod 105a is used to rotatably connect the low-frequency trap 104 to the mounting groove 103. One end of the rotating rod 105a is slidably fixed to the inner wall of the mounting groove 103, and the other end passes through the lower locking block 105c and the upper locking block 105b, and is connected to the fixing screw 105f by a thread. The upper locking block 105b is fixedly connected to the bottom of the mounting groove 103 and to the low-frequency trap 104, and is arranged opposite to the lower locking block 105c. Both of their opposing surfaces are provided with circumferential locking teeth 105e. The spring 105d is disposed between the upper locking block 105b and the lower locking block 105c, and when no force is applied, the spring 105d separates the two components. A fixing screw 105f is installed at the end of the rotating rod 105a. Rotating the fixing screw 105f causes the rotating rod 105a to move up and down. Since the other end of the rotating rod 105a is a non-circular structure, the lower locking block 105c and the low-frequency trap 104 will move up or down together, causing the lower locking block 105c to gradually approach the upper locking block 105b, or causing the lower locking block 105c to gradually separate from the upper locking block 105b. This continues until the circumferential locking teeth 105e of the two engage with each other, locking the low-frequency trap 104 in its current rotational position.

[0035] Furthermore, a groove is provided on one side of the low-frequency trap 104. In this embodiment, the operator can more easily apply torque through the groove, allowing the low-frequency trap 104 to rotate smoothly out of the mounting slot 103.

[0036] Furthermore, the mounting slot 103 is provided with protrusions 106 that correspond one-to-one with the openings on the low-frequency trap 104. In the hidden state, the protrusions 106 are inserted into the openings to block the low-frequency trap 104 and prevent dust from entering the interior of the low-frequency trap 104.

[0037] Furthermore, the protrusion 106 is also provided with a chamfer, wherein, in this embodiment, when the low-frequency trap 104 is rotated to the hidden state, the protrusion 106 can be smoothly inserted into the opening.

[0038] Furthermore, the low-frequency trap 104 has a chamfered contact angle. In this embodiment, the chamfer on the low-frequency trap 104 can reduce the impact when it comes into contact with the first wall 100 or the second wall 101 when switching to the use state.

[0039] Furthermore, the inner wall of one side of the mounting groove 103 is chamfered to reduce the impact when the back of the low-frequency trap 104 abuts against the side wall of the mounting groove 103 during use.

[0040] Furthermore, the low-frequency trap 104 is filled with porous sound-absorbing material to improve the absorption of low-frequency noise.

[0041] Working principle:

[0042] Concealed State: The low-frequency trap 104 is located inside the mounting groove 103, with its sound-absorbing surface fitting against the bottom of the mounting groove 103 to reduce dust ingress and maintain the overall aesthetics of the wall. At this time, the protrusion 106 inside the mounting groove 103 inserts into the corresponding opening on the low-frequency trap 104, further sealing the low-frequency trap 104 and preventing dust accumulation. Due to the action of the spring 105d, a certain gap is maintained between the lower locking block 105c and the upper locking block 105b, and the circumferential locking teeth 105e are not engaged, allowing the low-frequency trap 104 to rotate freely.

[0043] Usage state switching: When the low-frequency trap 104 needs to be used, force can be applied through the groove on the side of the trap to push the low-frequency trap 104 to rotate around the rotating rod 105a and leave the mounting slot 103. When it is rotated to the appropriate position, the fixing screw 105f is turned, which drives the rotating rod 105a to move upward. The lower locking block 105c and the low-frequency trap 104 will move upward together, so that the lower locking block 105c gradually approaches the upper locking block 105b until the circumferential locking teeth 105e of the two engage with each other, locking the low-frequency trap 104 in the current rotation position.

[0044] Reset Process: When the low-frequency trap 104 needs to be stored, rotate the fixing screw 105f, causing the rotating rod 105a to move downwards. This causes the lower locking block 105c to gradually move away from the upper locking block 105b, disengaging the circumferential locking teeth 105e and releasing the lock. Afterwards, the operator can rotate the low-frequency trap 104 in the opposite direction, allowing it to return to the mounting slot 103 around the rotating rod 105a. Because the mounting slot 103 contains an elastic element such as a spring 105d, the lower locking block 105c will automatically spring open under the elastic force, ensuring that the low-frequency trap 104 is stably stored when not in use.

[0045] Those skilled in the art will understand that numerous modifications are possible without substantially departing from the novel teachings and advantages of the subject matter described in this application. For example, variations in the size, dimensions, structure, shape, and proportions of various elements, as well as parameter values ​​such as temperature and pressure, installation arrangements, the use of materials, color, and orientation are possible. For instance, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature, number, or position of discrete elements may be changed or modified. Therefore, all such modifications are intended to be included within the scope of this invention.
