Description

Technical Field

[0001] This invention relates to the field of Bluetooth speaker technology, and in particular to a Bluetooth speaker that is easy to install at multiple angles on a wall and to be placed stably on the ground. Background Technology

[0002] Bluetooth speakers, as a typical example of wireless audio devices, achieve wireless transmission and playback of audio signals through Bluetooth technology. Their core principle is based on the audio transmission specifications of the Bluetooth protocol stack, combined with digital signal processing technology to achieve high-quality sound output.

[0003] Traditional Bluetooth speakers typically lack waterproofing. In bathrooms or other environments where moisture easily accumulates, water buildup can cause short circuits and other issues, resulting in poor waterproofing. To address these problems, Chinese patent CN114071273A discloses a Bluetooth speaker with a drainage channel within its waterproof component. When water splashes onto the speaker, it can drain through the channel. When moisture condenses on the inner wall of the channel, the component's sound-emitting action causes the waterproof component within the mounting cavity to vibrate, increasing the water accumulation rate and facilitating drainage along the channel. This prevents water from accumulating inside the speaker and causing short circuits.

[0004] This Bluetooth speaker is designed with portability in mind, being lightweight and compact, making it easy for users to carry around. However, due to limitations in its stable placement, it typically needs to be placed on a horizontal, flat table or other similar surface to ensure normal operation. As a result, the direction of the speaker's sound emission is basically kept on the same horizontal line or at a relatively fixed angle, which limits the diffusion range of sound waves during music playback. Consequently, the overall spatial sense and stereo experience of the sound effect appear rather monotonous. In addition, if the speaker is placed directly on a table or similar surface for an extended period of time, it may become unstable due to external interference or accidental collisions during daily use or movement, potentially leading to slippage or drops. This could affect the lifespan of the speaker itself and increase the risk of accidental damage. Summary of the Invention

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] (1) Through the flexible cooperation of the mounting mechanism and the L-shaped bracket, two installation methods can be achieved: stable placement at the bottom and hanging on the back wall. The mounting mechanism is inserted into the limiting hole of the L-shaped bracket at the bottom or back of the speaker body by inserting the plug rod. When the mounting mechanism is fixed at the bottom, the speaker can be stably placed on a horizontal surface such as a table or the ground. When the mounting mechanism is fixed at the back, the entire speaker can be suspended on a vertical wall by using the reserved bolts and suction cups, breaking the limitation of having to rely on a horizontal plane, so that the sound direction is no longer fixed on the same horizontal line, effectively widening the sound wave diffusion range. The surround design enhances the sense of spatial depth. The curved concave-convex surfaces between the rotating plate and the base plate, combined with the meshing structure of the toothed blocks and multiple sets of toothed grooves, allow for free adjustment and locking of the speaker's tilt angle. When the speaker body is lifted, the toothed blocks disengage from the toothed grooves, and the rotating plate can rotate around the crossbar, allowing the user to adjust the speaker's tilt angle arbitrarily. After being released, the toothed blocks automatically re-engage with the corresponding toothed grooves under the pull of the second reset spring, mechanically locking the new angle. This allows the sound direction to be tilted upwards or downwards as needed, further breaking the limitation of a single direction and enhancing the layering and enclosure of the sound. The speaker features a sleek design; the inner gear ring on the inner wall of the dome and the outer gear ring on the chassis form a horizontal rotation adjustment mechanism. Lifting the speaker upwards separates the inner and outer gear rings, allowing the speaker body to rotate horizontally and change the horizontal listening direction. Lowering the speaker causes a third reset spring to push the mechanism back to its original position, re-engaging and locking the inner and outer gear rings, achieving multi-angle horizontal fixation. Compared to traditional fixed-direction speakers, this allows for flexible adjustment of the sound field direction, improving the stereo listening experience. The anti-slip ring at the bottom of the base directly increases friction when placed on a flat surface, preventing slippage due to minor impacts or external forces. Dynamic displacement; the base is equipped with a liftable suction cup. Rotating the hollow threaded rod will cause the slide plate and suction cup to press down. The suction cup adheres tightly to the smooth contact surface through negative pressure, providing strong vertical fixation and significantly improving anti-tipping and anti-slip capabilities, preventing damage to the equipment due to accidental collisions. The threaded tube and reserved bolts on the base can directly lock the entire installation mechanism into the reserved installation holes on the wall or plane, achieving a reliable mechanical hard connection. This eliminates the risk of the speaker coming loose and falling when fixed to the wall, and it can remain stable even under large external interference.

[0026] (2) When the suction cup is released, simply pull out the sealing plug at the top of the hollow threaded rod. Outside air enters the suction cup through the hollow threaded rod, inner ring, and vent hole, quickly balancing the negative pressure and allowing the suction cup to easily detach from the contact surface. The speaker can be moved without strong prying, maintaining stability while allowing users to adjust the position at any time. The top box integrates an intake fan, an exhaust fan, a filter, and honeycomb activated carbon, forming a complete air purification channel. The fan can be remotely started and stopped via the first wireless control module to physically filter and adsorb odors and harmful substances in the surrounding air, achieving a beneficial air purification effect. The cylindrical cavity of the top box contains an aromatherapy module and an ambient light module, which are normally hidden inside. Pressing down the n-shaped handle bracket causes the function box to rise through gear and rack linkage, exposing the ambient light and aromatherapy module. Users can remotely control the aromatherapy module separately using the second wireless control module. The speaker box combines auditory, olfactory, and visual ambiance with a combination of lighting and sound. The n-shaped handle features a locking and unlocking mechanism with a pressure plate, pull rope, and insert block. When pressed down, the insert block automatically engages in the recessed hole, locking the lifting position. Pressing the pressure plate pulls the insert block out of the recessed hole, and the entire box automatically resets under the action of the fourth reset spring. The lifting and locking of the function box can be completed with one hand, making it convenient to use. Multiple access ports at the rear of the speaker body support connecting multiple speaker units in series via data cables, enabling multi-unit collaborative operation, expanding audio coverage and improving sound field consistency to meet the needs of larger spaces or stereo systems. The function box integrates a camera and voice control module for real-time environmental monitoring, enhancing safety. It also supports remote control of various speaker functions via voice commands, offering intuitive and efficient operation and reducing reliance on physical contact. Attached Figure Description

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0045] Reference Figure 1-13 This invention provides an embodiment of a Bluetooth speaker that is easy to install at multiple angles on a wall and stably placed on the ground. The speaker includes a speaker body 1. L-shaped brackets 2 are fixedly connected to both ends of the bottom of the speaker body 1. A support plate 31 is installed between the two sets of L-shaped brackets 2. The outer walls of the support plate 31 can tightly adhere to the opposite surfaces of the two sets of L-shaped brackets 2. A rotating plate 32 is fixedly connected to the bottom of the support plate 31. A base plate 33 is installed directly below the rotating plate 32. The bottom surface of the rotating plate 32 is designed as a smooth arc-shaped convex structure, while the top surface of the base plate 33 below it is designed as a corresponding concave shape, so that the arc-shaped convex surface at the bottom of the rotating plate 32 can perfectly and tightly fit against the inner wall of the arc-shaped concave surface at the top of the base plate 33. A round cover 34 is installed directly below the base plate 33. The bottom of the round cover 34 has an opening. A base 35 is installed directly below the round cover 34. Multiple sets of brackets are fixedly connected to the outer edge of the bottom of the base 35. Both block 365 and the bottom of the stand 365 are fixedly connected to a base 361. The bottom outer edge of the base 361 is fixedly connected to an anti-slip ring 362. By setting the anti-slip ring 362, the bottom can be stably attached to the contact surface in different usage scenarios. Whether placed on a flat ground, a smooth table, or fixed to a vertical wall, it can significantly enhance the overall stability and anti-slip ability of the speaker, thereby effectively improving the user experience and operational safety. The top end of the base 361 has a through-hole, and the inner wall of the hole is fixedly connected to a threaded tube 363. The inner wall of the threaded tube 363 is threaded with a reserved bolt 364. By setting the reserved bolt 364, it can be smoothly passed through the threaded tube 363, accurately aligned and inserted into the reserved hole of the installation position, thereby ensuring a reliable and stable fixed support for the entire Bluetooth speaker structure.

[0046] A square cavity 366 is formed at the center of the bottom of each base 361, and a through hole is formed at the center of the top of each base 361. A threaded ring 367 is fixedly connected to the inner wall of each through hole. The internal space of each square cavity 366 communicates with the internal space of each threaded ring 367. A hollow threaded rod 368 is threadedly connected to the inner wall of each threaded ring 367. A sealing plug 369 is fitted onto the top of the inner wall of each hollow threaded rod 368. An outer ring 3610 is fixedly connected to the outer edge of the bottom of each hollow threaded rod 368. An inner ring 3611 is rotatably connected to the inner wall of each outer ring 3610. The bottom of the inner ring 3611... Each slide plate 3612 is fixedly connected to the other two outer walls of the slide plate 3612, which are slidably connected to the inner walls of the square cavity 366. Each slide plate 3612 has a through-hole vent 3613 inside. Each slide plate 3612 has a suction cup 3614 fixedly connected to its bottom. The system comprises a base 361, an anti-slip ring 362, a threaded tube 363, a pre-installed bolt 364, a vertical block 365, a square cavity 366, a threaded ring 367, a hollow threaded rod 368, a sealing plug 369, an outer ring 3610, an inner ring 3611, a slide plate 3612, vents 3613, and suction cups 361. 4. It can form a placement mechanism 36. When the operator rotates the hollow threaded rod 368, its threaded structure rotates relative to the fixed threaded ring 367, driving the hollow threaded rod 368 to achieve longitudinal vertical displacement along the inner wall of the threaded ring 367. At the same time, the inner ring 3611 connected to the hollow threaded rod 368 and the slide plate 3612 at its bottom also move up and down synchronously. The suction cup 3614 fixed at the bottom of the slide plate 3612 also follows this movement trajectory to make vertical vertical adjustment. If the rotation direction causes the hollow threaded rod 368 to move downward, the suction cup 3614 will move downward. 14 can be stably pressed onto the smooth contact surface. Through negative pressure adsorption, the overall Bluetooth speaker structure is stably fixed and supported. The user removes the sealing plug 369 from the top of the hollow threaded rod 368. Outside air then passes through the hollow threaded rod 368, the inner ring 3611, and the vent 3613 in sequence, and finally smoothly enters the suction cup 3614. This airflow quickly balances the pressure environment inside the suction cup 3614, causing it to quickly lose its adsorption force on the contact surface, thus easily detaching from the contact surface, making the entire Bluetooth speaker easy to move and adjust.

[0047] A T-shaped cavity 37 is formed on the front end face of the support plate 31. The other two ends of the inner wall of the T-shaped cavity 37 are set on the outer walls of both sides of the support plate 31. Hollow rings 38 are fixedly connected to both ends of the inner wall of the T-shaped cavity 37. First spring rods 39 are slidably connected to the inner walls of the hollow rings 38. A lever 310 is fixedly connected to the opposite faces of the two sets of first spring rods 39. A first return spring 311 is sleeved on one end of the outer wall of the first spring rod 39. Insert rods 3 are fixedly connected to the opposite faces of the two sets of first spring rods 39. 12. By setting the first return spring 311, the elastic restoring force generated by it can stably and effectively push the insertion rod 312, so that the insertion rod 312 can overcome the resistance and extend synchronously and smoothly from both ends of the inner wall of the T-shaped cavity 37. By setting the lever 310, the user only needs to use two fingers to pull the two sets of levers 310 in opposite directions at the same time, and the two sets of extended insertion rods 312 can be smoothly retracted back into the internal space of the T-shaped cavity 37 by using this linkage mechanism. The base plate 33 Side plates 313 are fixedly connected to both outer walls. The bottom surface of the base plate 33 and the bottom surface of the side plates 313 are both set on the same horizontal plane. The interior of each side plate 313 is provided with sliding holes 314 that penetrate the outer walls on both sides. A toothed block 315 is fixedly connected to the arc-shaped convex surface at the bottom of the rotating plate 32. Multiple sets of toothed grooves 316 are provided on the arc-shaped concave surface at the top of the base plate 33. The outer wall of the toothed block 315 meshes with the inner wall of the toothed groove 316. By setting the connection structure between the toothed block 315 and the toothed groove 316, the rotating plate 32 and the base plate 33 can be effectively locked together. When the connection structure is fully engaged, the rotating plate 32 is firmly constrained and can no longer rotate or change position around the axis, thus achieving a stable fixed state. At the same time, this structure not only serves to connect and lock the rotating plate 32 and the base plate 33, but it also constitutes an important mechanical support system, which can provide additional support for the speaker body 1 installed on it, enhancing the stability and reliability of the entire structure.

[0048] Side blocks 317 are fixedly connected to the opposite sides of both sets of side plates 313. The bottom surface of the side blocks 317 and the bottom surface of the side plates 313 are both set on the same horizontal plane. Each side block 317 has a through spring hole 318. A second spring rod 319 is slidably connected to the top of the inner wall of each spring hole 318. A second return spring 320 is sleeved on the bottom of the outer wall of each second spring rod 319. A first threaded shaft 321 is fixedly connected to the center of the bottom of each second spring rod 319. A first nut 322 is threadedly connected to the outer wall of each first threaded shaft 321. The bottom end of the second return spring 320 can contact the top surface of the first nut 322, thereby restoring the first return spring 320. Nut 322 applies a continuous downward pushing force. Under the influence of this force, the second spring rod 319 at the top of the first threaded shaft 321 can be smoothly pulled back into the internal space of the spring hole 318. By setting a threaded connection structure between the first threaded shaft 321 and the first nut 322, the second return spring 320 can be firmly fixed on the outer wall of the second spring rod 319. By setting a simple connection method between the first threaded shaft 321 and the first nut 322, the installation and disassembly steps of the second return spring 320 become more convenient and quick, significantly improving the efficiency of maintenance and assembly work.

The inner wall of the rotating hole is rotatably connected to the center of the outer wall of the crossbar 324. Both ends of the outer wall of the crossbar 324 are slidably connected to the inner wall of the sliding hole 314. When the user lifts the speaker body 1 upward, this action will drive the rotating plate 32 and the crossbar 324 connected to it to slide upward along the set path. As the sliding proceeds, the tooth block that was originally stuck in the toothed groove 316 is released. 315 will gradually disengage from the slot, thereby releasing the locking constraint on the rotating plate 32. At this time, the entire mechanism is in an adjustable state. In this state, the user can freely rotate the rotating plate 32 and the speaker body 1 connected to it to adjust the orientation or tilt angle of the device. After the angle is adjusted, the user only needs to slowly lower the speaker body 1. Under the combined guidance of the elastic tension provided by the second return spring 320 and the sliding direction set by the second spring rod 319, the tooth block 315 will automatically re-insert into the toothed groove 316 corresponding to another position, thereby completing the mechanical locking of the adjusted position and ensuring that the speaker body 1 remains stable in subsequent use.

A third return spring 329 is sleeved on the top end of the outer wall of the third spring rod 328. A second threaded shaft 330 is fixedly connected to the top of the third spring rod 328. The outer wall of 330 is threaded with a second nut 331. The bottom end of the third return spring 329 can contact the top surface of the slip ring 326, thereby applying a continuous downward pushing force to the slip ring 326. Under the influence of this force, the third spring rod 328 at the bottom of the second threaded shaft 330 can be smoothly pulled back into the internal space of the hollow tube 325. By setting the threaded connection structure between the second threaded shaft 330 and the second nut 331, the third return spring 329 can be firmly fixed on the outer wall of the third spring rod 328. By setting the simple connection method between the second threaded shaft 330 and the second nut 331, the installation and disassembly steps of the third return spring 329 become more convenient and quick, significantly improving the efficiency of maintenance and assembly work. It is worth noting that before disassembling the second nut 331, the hollow tube 325 and the slip ring 326 need to be separated.

The outer gear ring 335 and the inner gear ring 336 can form the mounting mechanism 3. During operation, if the user applies an upward lifting force to the speaker body 1, the toothed block 315 at the bottom of the rotating plate 32 will first disengage from the toothed groove 316 it engages with. Then, as the user continues to lift the speaker body 1 upward, the bottom plate 33 connected to it will simultaneously drive the round cover 34 located below it to slide upward along a predetermined track. Immediately afterwards, the inner gear ring 336 will separate from the originally meshing outer gear ring 335. At the same time, the third return spring 329 will begin to be compressed and stored during this process. By storing elastic potential energy, the user can then rotate the entire speaker body 1 to flexibly adjust its orientation. Once the speaker body 1 is in the target position, the user only needs to slowly lower it back down. Under the combined guidance and constraint of the elastic restoring force released by the third return spring 329 and the specific sliding path defined by the third spring rod 328, the inner gear ring 336 and the outer gear ring 335 will re-engage securely. This structure ensures that the speaker body 1 can be effectively and reliably locked after the orientation adjustment is completed, maintaining the stability of its set orientation.

[0051] The L-shaped bracket 2 has multiple sets of limiting holes 4 inside. One end of the outer wall of the plug rod 312 is sleeved with the inner wall of the limiting hole 4. By setting the connection structure between the plug rod 312 and the limiting hole 4, the mounting mechanism 3 can be firmly assembled onto the speaker body 1. Considering that the bottom and back of the speaker body 1 are both equipped with L-shaped brackets 2, the mounting mechanism 3 can be flexibly fixed to the bottom or back of the speaker body 1 according to the actual installation requirements. If the mounting mechanism 3 is set at the bottom of the speaker body 1, the entire Bluetooth speaker can be stably placed on the ground or various horizontal surfaces such as desktops. If the mounting mechanism 3 is set at the back of the speaker body 1, the entire Bluetooth speaker can be suspended or fixed to a vertical wall in a corresponding way, thereby realizing diverse installation and placement methods.

The snap-fit ​​connection structure between the limiting plate 546 and the locking block 547 and the housing 543 ensures that the housing 543 is stably fixed. Inside its corresponding embedding hole 542, this structure effectively eliminates any potential loosening or shaking of the outer casing 543, enhancing the overall structural stability. When maintenance or replacement of internal components is required, the operator only needs to smoothly pull the entire housing 541 out of the cavity of the top box 51, and then easily pull out the fixing limit plate 546 from the embedding hole 542, making subsequent disassembly and replacement of the outer casing 543 very simple and efficient. The air inlet 548, the air outlet 549, and the internal space of the embedding hole 542 constitute a complete gas flow channel. The gas to be treated from the outside is first introduced into the cavity of the embedding hole 542 through the air inlet 548, and then orderly discharged through the air outlet 549. To significantly improve the efficiency of this gas circulation process, an intake fan 5410 and an exhaust fan 5411 are installed. Their coordinated operation can greatly accelerate the gas flow speed throughout the entire path. The first wireless control module 5412 provides great convenience for users, allowing them to flexibly control the start and stop of the intake fan 5410 and the exhaust fan 5411 remotely. When the gas flows through the inside of the housing 543, the filter 544 and the multi-layer honeycomb activated carbon 545 play a key role. They perform step-by-step physical filtration and chemical adsorption treatment on various odor molecules and harmful and toxic substances mixed in the gas, thereby efficiently removing pollutants and ultimately achieving excellent air purification effect, ensuring the cleanliness and safety of the output air.

The teeth on the opposite sides of the first gear rack 511 and the second gear rack 522 mesh with the inner wall of the gear groove body 515. By setting the second wireless control module 519, users can flexibly switch the aromatherapy module 517 and the ambient light module 518 integrated inside the function box 516 without directly contacting the device body, realizing effective remote control of their working status. At the same time, by setting the connection between the slider 521 and the slide tube 520, the guiding and running stability of the function box 516 when sliding up and down along the slider 521 can be improved. This design effectively prevents shaking or jamming. When the user applies downward pressure to the n-shaped handle 57 on top of the device, the slider 55 and the first gear rack 511 at the rear end also move downwards. Since the first gear rack 511 is always meshed with a centrally mounted gear body 514, the downward movement of the first gear rack 511 drives the gear body 514 to rotate. The rotation of the gear body 514 then drives the second gear rack 522, which is meshed with it on the other side, to move in the opposite direction, i.e., upwards. The upward movement of the second gear rack 522 directly pulls the function box 516 upwards smoothly. As the n-shaped handle 57 is continuously pressed until the preset depth is reached, the function box 516 will rise to a specific position.At this point, the ambient light module 518 on the outer wall of the function box 516 will be fully visible to the outside, achieving the ideal lighting or ambiance preparation state. In this state, the user can send commands to the second wireless control module 519 to remotely activate the aromatherapy module 517 inside the function box 516 to release fragrance, or to light up the ambient light module 518 to create a light and shadow atmosphere, or both can be activated simultaneously to achieve a multi-sensory experience.

The system includes a top box 51, a convex cavity 52, a cylindrical cavity 53, an air purification mechanism 54, a slider 55, a fourth spring rod 56, an n-shaped handle bracket 57, a perforated plate 58, a fourth return spring 59, a concave hole 510, a first gear rack 511, a gear cavity 512, a shaft 513, a gear body 514, a toothed body 515, a function box 516, an aromatherapy module 517, an ambient light module 518, a second wireless control module 519, a slide tube 520, a slide rod 521, and a second gear rack. 522, 523, 524, 525, 526, 527, 528, 529, 522, and 530 together form a functional mechanism 5. The push spring 530 provides a continuous and stable pushing force to the insert 529, ensuring it is always ready. When the operator slides the n-shaped handle 57 downwards along a preset trajectory, the insert 529 accurately aligns with and perfectly engages with the preset recess 510 inside the convex cavity 52, thus firmly inserting itself. This structure allows the pressed n-shaped handle 57 to be... The fixed position prevents it from rebounding. When the user needs to apply downward pressure to the pressure plate 524, the two sets of pull ropes 525 connected to the pressure plate 524 will respond immediately and apply a pulling force to the insert 529 at the end. Under the action of this pulling force, the two sets of inserts 529 will quickly and synchronously disengage from the recess 510 and slide into the guide hole 527 along the preset path. At the same time, under the strong restoring force released by the fourth return spring 59, the slider 55 and its connected n-type handle bracket 57 will immediately slide upward quickly and smoothly until they are completely restored to their initial ready position, completing a complete operation cycle.
