Description

Technical Field

[0001] This utility model relates to the field of speaker technology, specifically to a foldable sound guide tube structure for a sound field control speaker device. Background Technology

[0002] A sound field controllable speaker system is an audio device capable of flexibly adjusting the sound field characteristics. Compared to traditional speakers, this system achieves precise sound guidance and distribution through advanced acoustic design and control mechanisms, enhancing sound clarity and spatiality. By dynamically adjusting the sound wave propagation path, sound field controllable speakers adapt to different environmental conditions and listening needs, providing an excellent audio experience in various scenarios, especially suitable for outdoor, home theater, and professional audio applications. In this context, the sound guide tube, as a key component of the sound field controllable speaker system, plays a particularly important role. The sound guide tube not only guides the sound propagation path but also optimizes the diffusion of sound waves through design, thereby achieving higher quality audio output.

[0003] Patent CN210694255U discloses an outdoor patio speaker system, which includes a speaker and a sound-conducting tube communicating with the interior of the speaker. The inner wall of the sound-conducting tube is coated with sound-absorbing material, and the sound-conducting tube is made of flexible material. The end of the sound-conducting tube away from the speaker is used for fixed connection to a support surface. The speaker forms independent left and right cavities through a partition. One end of the partition is connected to the upper inner wall of the speaker, and the other end is connected to the lower inner wall of the speaker. The partition maintains a preset angle with both the upper and lower inner walls of the speaker. A first mounting hole is provided on the partition, and a speaker is provided in the first mounting hole. The speaker's sound guide port faces the connection port between the sound-conducting tube and the speaker. The speaker also has a signal input interface. The outdoor patio speaker system designed by this utility model reduces distortion and noise by setting up a sound-conducting tube. When the speaker is installed in a general environment, it conducts sound to the desired location through pipe-like sound wave propagation.

[0004] The aforementioned existing technologies, by incorporating a sound-conducting tube, aim to reduce sound distortion and noise. When the speaker is installed in a typical environment, sound is effectively conducted to the desired location and can cover a considerable distance via the tube-like sound wave propagation. However, the sound-conducting tube is made of flexible material. While this allows for a degree of portability, this characteristic can lead to uneven deployment during use, resulting in ripples. These ripples affect sound wave propagation and consequently have a significant negative impact on sound quality. Therefore, we propose a foldable sound-conducting tube structure for a sound field-controlled speaker device. This novel structure solves the problem of uneven deployment of the sound-conducting tube in existing technologies, thereby improving sound quality performance. Utility Model Content

[0005] The purpose of this invention is to provide a foldable sound tube structure for a sound field controllable speaker device, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The sound field controllable speaker enclosure features a foldable sound guide tube structure, including an inlet hard tube and an outlet hard tube. The inlet hard tube receives the sound waves output from the speaker's bass reflex port and guides them to the sound guide tube system. The outlet hard tube directs the adjusted sound waves to the target area, such as... Figure 2 As shown, several sound-conducting hard tubes are provided between the inlet hard tube and the outlet hard tube. The sound-conducting hard tubes are used to form a rigid sound-conducting channel to reduce deformation interference in sound wave propagation. The number of sound-conducting hard tubes is selected according to the actual site. The inlet hard tube is connected to the adjacent sound-conducting hard tube through a sound-conducting flexible tube. The outlet hard tube is connected to the adjacent sound-conducting hard tube through a sound-conducting flexible tube. Two adjacent sound-conducting hard tubes are connected through a sound-conducting flexible tube. The sound-conducting flexible tube has a certain degree of flexibility to adapt to the angle adjustment of two adjacent sound-conducting tubes and to fold and store them.

[0008] The sound inlet hard tube is connected to the adjacent sound guide hard tube via a connector, and the sound outlet hard tube is connected to the adjacent sound guide hard tube via a connector. Two adjacent sound guide hard tubes are connected via a connector. The connector is used to adjust the connection angle of adjacent sound guide tubes and fix their positions, making it convenient for staff to adjust the installation position of the sound guide tubes.

[0009] Preferred, such as Figure 4 As shown, the connector includes a short sleeve, which is used to fit and fix the right end of the sound inlet tube or the sound guide tube. The outer wall of the short sleeve and near the right side are provided with two symmetrically arranged threaded posts. The threaded posts are used to cooperate with the connecting rod to achieve angle adjustment. The outer sides of the two threaded posts are rotatably connected to the connecting rod, which is used to adjust the unfolding angle of the sound guide tube by sliding and rotating.

[0010] Both of the two connecting rods have circular holes on their opposite sides and near the left end for threaded posts to pass through. The circular holes are used to accommodate the threaded posts and allow the connecting rods to rotate around them. The threaded posts pass through the circular holes and are threadedly connected to a clamping knob. The clamping knob is used to lock the connecting rods to prevent them from loosening after angle adjustment.

[0011] The short sleeve has four first fixing bolts arranged in a circular array on its outer wall and near the left side. The first fixing bolts are used to fix the connection between the short sleeve and the entrance sound tube or the sound guide tube.

[0012] Both the sound inlet tube and the sound guide tube have a first annular limiting block on their outer wall near the right end. The right side of the first annular limiting block fits against the left side of the short sleeve. The first annular limiting block is used to limit the displacement of the short sleeve and ensure connection stability.

[0013] Preferred, such as Figure 5 As shown, the connector also includes a long sleeve, which is used to fit and fix the left end of the sound outlet tube or the sound guide tube. The outer wall of the long sleeve has two symmetrically arranged sliding grooves, which are used to guide the circular slider to slide to adjust the unfolding angle of the sound guide tube. Circular sliders are provided on the opposite sides of the two connecting rods near the right end. The two circular sliders are slidably connected in the two sliding grooves, and the circular sliders are used to slide in the sliding grooves and transmit the adjusting force.

[0014] The outer wall of the long sleeve and near the right side are threaded with four second fixing bolts arranged in a circular array. The second fixing bolts are used to fix the connection between the long sleeve and the sound outlet hard tube or the sound guide hard tube.

[0015] The outer wall of both the sound-emitting rigid tube and the sound-conducting rigid tube is provided with a second annular limiting block near the left end. The left side of the second annular limiting block is in contact with the right side of the long sleeve. The second annular limiting block is used to limit the displacement of the long sleeve and prevent the connection from becoming loose.

[0016] Preferred, such as Figure 4 As shown, threaded holes are provided on the opposite sides of the two connecting rods near the right end. A clamping bolt is threaded into the threaded hole. The threaded end of the clamping bolt passes through the annular slider and abuts against the inner wall of the groove, thereby fixing the position of the connecting rod and the long sleeve, thus fixing the relative position of the short sleeve and the long sleeve, and thus ensuring that the positions of the two adjacent sound guide pipes are fixed.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The foldable sound tube structure of this sound field controllable speaker device, through the rigidity and adjustable structure of the sound tube and connector, keeps the sound tube flat and unfolded during use, avoiding ripples caused by stretching of flexible materials, thereby reducing distortion in sound wave propagation and significantly improving sound quality clarity.

[0019] 2. The foldable sound tube structure of this sound field control speaker device, with the matching design of the sliding groove and the circular slider in the connector, allows users to adjust the unfolding angle of the sound tube according to actual environmental needs, optimize the sound field distribution, and adapt to the listening needs of different scenarios.

[0020] 3. The foldable sound guide tube structure of this sound field controllable speaker device, through the cooperation of short sleeve, long sleeve and annular limiting block, combined with the locking effect of fixing bolts, ensures that all components are tightly connected in the unfolded state of the sound guide tube, avoids loosening of the sound guide tube, and ensures the stability of the sound wave transmission path.

[0021] 4. The foldable sound guide tube structure of this sound field control speaker device, with the combination design of rigid and flexible sound guide tubes, can be folded for easy storage and can also maintain the straightness of the sound wave propagation path when unfolded by using the rigid sound guide tube, reducing sound energy loss and ensuring balanced sound output.

[0030] Please see Figures 1-5 This utility model provides a technical solution:

[0031] The sound field controllable speaker enclosure features a foldable sound guide tube structure, including an inlet hard tube 1 and an outlet hard tube 2. The inlet hard tube 1 receives the sound waves output from the speaker's bass reflex port and guides them to the sound guide tube system. The outlet hard tube 2 directs the adjusted sound waves to the target area, such as... Figure 2 As shown, several sound guiding tubes 3 are provided between the inlet hard tube 1 and the outlet hard tube 2. The sound guiding tubes 3 are used to form a rigid sound guiding channel to reduce deformation interference in sound wave propagation. The number of sound guiding tubes 3 is selected according to the actual site. The inlet hard tube 1 is connected to the adjacent sound guiding tube 3 through the sound guiding hose 4. The outlet hard tube 2 is connected to the adjacent sound guiding tube 3 through the sound guiding hose 4. Two adjacent sound guiding tubes 3 are connected through the sound guiding hose 4. The sound guiding hose 4 has a certain degree of flexibility to adapt to the angle adjustment of two adjacent sound guiding tubes and to fold and store them.

[0032] The sound inlet hard tube 1 is connected to the adjacent sound guide hard tube 3 via connector 5, and the sound outlet hard tube 2 is connected to the adjacent sound guide hard tube 3 via connector 5. The two adjacent sound guide hard tubes 3 are connected via connector 5. Connector 5 is used to adjust the connection angle of adjacent sound guide tubes and fix their positions, making it convenient for staff to adjust the installation position of the sound guide tubes.

[0033] In this embodiment, as Figure 4 As shown, the connector 5 includes a short sleeve 50, which is used to fit and fix the right end of the sound inlet tube 1 or the sound guide tube 3. Two symmetrically arranged threaded posts 51 are provided on the outer wall of the short sleeve 50 near the right side. The threaded posts 51 are used to cooperate with the connecting rod 52 to achieve angle adjustment. The connecting rod 52 is rotatably connected to the outer side of the two threaded posts 51. The connecting rod 52 is used to adjust the unfolding angle of the sound guide tube 3 by sliding and rotating.

[0034] Both connecting rods 52 have a circular hole 520 on their opposite sides and near the left end for the threaded post 51 to pass through. The circular hole 520 is used to accommodate the threaded post 51 and allow the connecting rod 52 to rotate around it. The threaded post 51 passes through the circular hole 520 and is threadedly connected to a clamping knob 53. The clamping knob 53 is used to lock the connecting rod 52 to prevent it from loosening after the angle is adjusted.

[0035] The outer wall of the short sleeve 50 and near the left side are threaded with four first fixing bolts 54 arranged in a ring array. The threaded end of the first fixing bolt 54 abuts against the outer wall of the sound inlet tube 1 or the sound guide tube 3. The first fixing bolts 54 are used to fix the connection between the short sleeve 50 and the sound inlet tube 1 or the sound guide tube 3.

[0036] Both the sound inlet tube 1 and the sound guide tube 3 have a first annular limiting block 6 on their outer walls near the right end. The right side of the first annular limiting block 6 is in contact with the left side of the short sleeve 50. The first annular limiting block 6 is used to limit the displacement of the short sleeve 50 and ensure connection stability.

[0037] Specifically, such as Figure 5 As shown, the connector 5 also includes a long sleeve 55, which is used to fit and fix the left end of the sound-emitting hard tube 2 or the sound-conducting hard tube 3. The outer wall of the long sleeve 55 has two symmetrically arranged sliding grooves 550, which are used to guide the circular slider 521 to slide to adjust the unfolding angle of the sound-conducting hard tube 3. Circular sliders 521 are provided on the opposite sides of the two connecting rods 52 near the right end. The two circular sliders 521 are slidably connected in the two sliding grooves 550 respectively. The circular sliders 521 are used to slide in the sliding grooves 550 and transmit the adjustment force.

[0038] Four second fixing bolts 56 arranged in a ring array are threaded on the outer wall of the long sleeve 55 near the right side. The threaded end of the second fixing bolt 56 abuts against the outer wall of the sound outlet hard tube 2 or the sound guide hard tube 3. The second fixing bolts 56 are used to fix the connection between the long sleeve 55 and the sound outlet hard tube 2 or the sound guide hard tube 3.

[0039] The outer wall of both the sound-emitting rigid tube 2 and the sound-conducting rigid tube 3, near the left end, is provided with a second annular limiting block 7. The left side of the second annular limiting block 7 is in contact with the right side of the long sleeve 55. The second annular limiting block 7 is used to limit the displacement of the long sleeve 55 and prevent the connection from becoming loose.

[0040] Furthermore, such as Figure 4As shown, threaded holes 522 are provided on the opposite sides of the two connecting rods 52 near the right end. The threaded holes 522 are threaded with clamping bolts 57. The threaded end of the clamping bolts 57 passes through the annular slider 521 and abuts against the inner wall of the groove 550, thereby fixing the position of the connecting rods 52 and the long sleeve 55, thus fixing the relative position of the short sleeve 50 and the long sleeve 55, and thus ensuring that the positions of the two adjacent sound guide pipes are fixed.

[0041] In this embodiment, the foldable sound guide tube structure of the sound field controllable speaker device is used by first connecting the inlet hard tube 1 to the bass reflex port of the speaker, and selecting the number of sound guide tubes 3 according to the actual site requirements. The inlet hard tube 1, sound guide tube 3, and outlet hard tube 2 are connected in series through the sound guide hose 4. When connecting adjacent pipes, the angle and position are adjusted by the connector 5: the short sleeve 50 is fitted into the right end of the sound hard tube 1 or the sound guide tube 3 and locked with the first fixing bolt 54, while the displacement of the short sleeve 50 is limited by the first annular limiting block 6; the long sleeve 55 is fitted into the left end of the outlet hard tube 2 or the sound guide tube 3 and locked with the second fixing bolt 56, while the long sleeve is limited by the second annular limiting block 7. The displacement of the sound guide tube 3 is adjusted by rotating the connecting rod 52, so that the annular slider 521 slides along the groove 550 of the long sleeve 55 to the target position. Then, the threaded post 51 is locked by the clamping knob 53 to fix the angle of the connecting rod 52. Finally, the clamping bolt 57 passes through the threaded hole 522 of the connecting rod 52 and abuts against the inner wall of the groove 550 to further fix the unfolded state of the sound guide tube 3. After the adjustment is completed, the flexibility of the sound guide hose 4 can adapt to the angle change of the adjacent sound guide tube 3. When folding, the reverse operation can be used to store it. This structure, through the combination of the rigid sound guide tube 3 and the adjustable connector 5, ensures the flatness of the sound wave propagation path, while taking into account portability and sound quality stability.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
