Description

Technical Field

[0001] The present invention relates to the technical field of smart speakers, and in particular to a smart speaker with adaptive noise reduction. Background Art

[0002] As smart homes become increasingly popular, smart speakers, serving as a bridge between digital life and physical space, have become a focus of consumer attention for their performance and user experience. Adaptive noise reduction technology, a key component in improving sound quality, not only effectively blocks external noise but also ensures pure and clear sound quality. However, the practical application of any technology is accompanied by certain challenges and shortcomings, and the structural design of adaptive noise reduction smart speakers is no exception. When using a smart speaker, friction noise is easily generated between the base and the speaker body due to factors such as material hardness and contact area. Secondly, in traditional designs, noise reduction components are often built directly into the speaker, lacking effective sound insulation measures, allowing external noise to still penetrate the cabinet to a certain extent, affecting the purity of the sound quality. At the same time, the precision electronic components of smart speakers are relatively sensitive to environmental conditions, and even fine dust particles may cause damage to them. The lack of an effective protection mechanism not only shortens the product lifespan, but may also cause failures and affect the user experience. Summary of the Invention

[0003] The present invention proposes an adaptive noise reduction smart speaker, which solves the friction noise problem of existing adaptive noise reduction smart speakers, as well as the problems of poor noise reduction effect and insufficient dustproof ability.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: An adaptive noise reduction smart speaker comprises a base, a shock absorber is provided inside the base, and an annular mounting plate is fixedly connected to the top of the shock absorber, multiple groups of limit grooves are provided inside the mounting groove, and a shock absorbing mechanism is provided outside the limit groove, a mounting seat is provided on the top of the annular mounting plate, and a matching smart speaker body is placed inside the mounting seat, a dustproof and noise reduction mechanism is provided on the outside of the smart speaker body, and a removable dust cover is provided on the top of the base, and an adjustment mechanism is provided inside the dust cover; The adjustment mechanism includes a first sound outlet, a rotating cover, a rotating shaft, and a groove. The first sound outlet is provided inside the dust cover. A rotating cover is installed inside the first sound outlet through the rotating shaft, and a groove is provided on the outside of the rotating cover.

[0005] Preferably, a plurality of groups of rubber gaskets are provided at the bottom of the base, and a mounting groove is provided inside the base, and the shock absorber is located in the middle of the mounting groove.

[0006] Preferably, the shock-absorbing mechanism includes a slide, a slider, a connecting rod, a rotating shaft, a first groove, a second groove, a damping telescopic rod, and a spring, and a slide is provided inside the installation groove in the middle of the limiting groove, a damping telescopic rod is provided on the inside of the limiting groove, and a spring is provided on the outside of the damping telescopic rod, and a slider matching the slide is provided on the side of the damping telescopic rod in a sliding connection.

[0007] Preferably, a first groove is provided inside the slider, and a second groove is provided inside the annular mounting plate, and a connecting rod is installed inside the first groove and the second groove via a rotating shaft.

[0008] Preferably, a connecting groove is provided on the top of the base outside the installation groove, and a shock-absorbing airbag is provided inside the connecting groove, and the shock-absorbing airbag is sleeved on the outside of the mounting seat.

[0009] Preferably, a sleeve airbag is provided on the inner side of the mounting seat, and the smart speaker body is placed inside the sleeve airbag.

[0010] Preferably, a speaker is provided on the outside of the smart speaker body at one end, and a heat dissipation port is provided on the outside of the smart speaker body at the other end.

[0011] Preferably, the dust-proof and noise-reduction mechanism includes a limit seat, noise-reduction cotton, a second sound outlet, a filter, a limit cover, bolts, and heat dissipation holes, and a limit seat is provided at the bottom of the smart speaker body, noise-reduction cotton is provided inside the limit seat, and a second sound outlet matching the speaker is provided inside the noise-reduction cotton at one end, and a heat dissipation hole matching the heat dissipation port is provided inside the noise-reduction cotton at the other end.

[0012] Preferably, a filter is provided on the outside of the noise reduction cotton, and a limit cover is installed on the top of the smart speaker body by bolts, and the filter and noise reduction cotton are both located inside the limit cover.

[0013] Preferably, a fixing groove is provided on the top of the base, and a dust cover is clamped inside the fixing groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This adaptive noise reduction smart speaker has a shock absorber in the middle of the installation slot, connecting rods are installed inside the first and second grooves through a rotating shaft, and a damping telescopic rod and a spring are provided inside the limit slot. When the smart speaker shakes, the shock absorber inside the installation slot can respond quickly, perform initial shock absorption, and alleviate the shaking force. Then, the shock absorber is dispersed to each damping telescopic rod and spring through the connecting rod to further eliminate the shaking force, realizing dynamic adjustment of the shock absorption effect, ensuring the stability of the speaker in different vibration environments, enhancing the speaker's anti-shake ability, reducing the generation of friction noise, and bringing a quieter user experience.

[0015] 2. When the speaker is subjected to external force or shakes during use, the shock-absorbing airbag first absorbs part of the vibration energy. At the same time, the expanded sleeve airbag forms an additional buffer layer to further reduce the impact of vibration on the speaker body. In addition, the expanded state of the sleeve airbag can effectively offset the gap caused by shaking, reduce the noise caused by gap changes, and improve the noise reduction effect. Secondly, a layer of high-quality noise reduction cotton is cleverly attached to the outer side of the smart speaker body, which fully utilizes the sound absorption characteristics of the noise reduction cotton material, effectively isolates external noise, significantly improves the sound quality performance of the speaker in complex environments, and further improves the noise reduction effect.

[0016] 3. A dust cover that is easy to disassemble is set on the top of the base, and a filter is set on the outside of the noise reduction cotton. The double protection mechanism, combined with the use of noise reduction cotton, can effectively block tiny dust particles from entering the speaker, reducing the risk of failure caused by dust accumulation, and further improving the dustproof ability of the adaptive noise reduction smart speaker.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1 Reference Figure 1-Figure 7 The present invention provides a technical solution: an adaptive noise reduction smart speaker, comprising a base 1, a mounting slot 2 is provided inside the base 1, a shock absorber 3 is provided in the middle of the mounting slot 2, an annular mounting plate 4 is fixedly connected to the top of the shock absorber 3, and multiple groups of limit slots 5 are provided on the inner side of the mounting slot 2, and a shock-absorbing mechanism is provided on the outer side of the limit slot 5.

[0027] Reference Figure 5 , Figure 7 The shock-absorbing mechanism includes a slide 11, a slider 12, a connecting rod 13, a rotating shaft 14, a first groove 15, a second groove 151, a damping telescopic rod 16, and a spring 17. The slide 11 is provided inside the mounting groove 2 in the middle of the limiting groove 5, and the damping telescopic rod 16 is installed on the inside of the limiting groove 5, and the spring 17 is provided on the outside of the damping telescopic rod 16. The side of the damping telescopic rod 16 is provided with a slider 12 matching the slide 11 and is slidably connected. The slider 12 is provided with a first groove 15, and the annular mounting plate 4 is provided with a second groove 151. The first groove 15 and the second groove 151 are installed with a connecting rod 13 through the rotating shaft 14, and then the annular mounting plate 4 and the slider 12 are movably connected through the connecting rod 13, which helps to disperse the shaking force.

[0028] Reference Figure 1 , multiple groups of rubber gaskets 10 are provided at the bottom of the base 1. The rubber gaskets 10 have an elastic supporting function, which can alleviate the vibration generated by the smart speaker body 7 when in use and reduce noise.

[0029] In a specific implementation, an adaptive noise reduction smart speaker, when the smart speaker is shaking, first the rubber gasket 10 at the bottom of the base 1 has an elastic support function, which can alleviate the vibration generated by the use of the smart speaker body 7. Then, the annular mounting plate 4 generates a downward pressure and shaking force under the action of the mounting base 6 fixed above and the internal smart speaker body 7 (reference Figure 5 , Figure 6 ) First, the shock absorber 3 uses its own shock-absorbing effect to initially alleviate the downward shaking force. Then, the remaining downward shaking force is dispersed to each damping telescopic rod 16 and spring 17 through the connecting rod 13, so that the slider 12 moves toward the damping telescopic rod 16 and spring 17 inside the slide 11. At the same time, because the damping telescopic rod 16 and spring 17 have a shock-absorbing effect, the downward shaking force is further eliminated, and then the shock absorber 3, the damping telescopic rod 16 and the spring 17 adaptively eliminate the downward shaking force. Through the above operation, the dynamic adjustment of the shock absorption effect is achieved, the anti-shaking ability of the speaker is enhanced, the generation of friction noise is reduced, and a quieter user experience is brought to the user.

[0030] Example 2 Reference Figure 2 , this embodiment is optimized on the basis of embodiment 1. A mounting seat 6 is provided on the top of the annular mounting plate 4, and a matching smart speaker body 7 is placed inside the mounting seat 6. A dustproof and noise reduction mechanism is provided on the outside of the smart speaker body 7, and a dust cover 9 that is easy to disassemble is provided on the top of the base 1. An adjustment mechanism is provided inside the dust cover 9. The adjustment mechanism includes a first sound outlet 31, a rotating cover 32, a rotating shaft 33, and a groove 34. The first sound outlet 31 is provided inside the dust cover 9, and a rotating cover 32 is installed inside the first sound outlet 31 through the rotating shaft 33, and a groove 34 is provided on the outside of the rotating cover 32. The rotating cover 32 is rotated by the rotating shaft 33 to adjust the opening and closing size of the first sound outlet 31, which can effectively prevent dust and fine particles from entering the interior of the smart speaker body 7 without causing obvious obstruction to the transmission of sound.

[0031] Reference Figure 3 , Figure 4 A connecting groove 18 is provided on the outside of the mounting groove 2 at the top of the base 1, and a shock-absorbing airbag 19 is provided inside the connecting groove 18. The shock-absorbing airbag 19 is sleeved on the outside of the mounting seat 6, and a sleeve airbag 27 is sleeved on the inside of the mounting seat 6. The smart speaker body 7 is placed inside the sleeve airbag 27. When the sleeve airbag 27 is in the expanded state, the gap between the smart speaker body 7 and the mounting seat 6 can be further reduced, thereby reducing noise generation and helping to improve the noise reduction effect.

[0032] Reference Figure 2 , Figure 6, a speaker 28 is provided on the outside of the smart speaker body 7 at one end, and a heat dissipation port 29 is provided on the outside of the smart speaker body 7 at the other end. The dust-proof and noise reduction mechanism includes a limit seat 20, noise reduction cotton 21, a second sound outlet 22, a filter 23, a limit cover 24, a bolt 25, and a heat dissipation hole 26. A limit seat 20 is provided at the bottom of the smart speaker body 7, and noise reduction cotton 21 is provided inside the limit seat 20. The noise reduction cotton 21 is made of a material with sound absorption efficiency and air permeability to ensure that the normal heat dissipation of the internal components of the speaker is not affected while improving the sound quality. A second sound outlet 22 matching the speaker 28 is provided inside the noise reduction cotton 21 at one end. The setting of the second sound outlet 22 helps to improve the sound quality of the smart speaker body 7. A heat dissipation hole 26 matching the heat dissipation port 29 is provided inside the noise reduction cotton 21 at the other end. The heat dissipation hole 26 further improves the heat dissipation efficiency of the smart speaker body 7, ensures its long-term stable operation, and helps to improve the user experience.

[0033] Reference Figure 1 , Figure 4 A filter 23 is provided on the outside of the noise reduction cotton 21, and a limit cover 24 is installed on the top of the smart speaker body 7 through a bolt 25. The filter 23 and the noise reduction cotton 21 are both located inside the limit cover 24. Manually turning the bolt 25 facilitates the disassembly and installation of the limit cover 24. After removing the limit cover 24, it is convenient to replace the noise reduction cotton 21 and the filter 23, making its maintenance more convenient. Regular replacement of the noise reduction cotton 21 and the filter 23 ensures the sound quality and dustproof effect of the smart speaker body 7, which helps to extend the service life of the smart speaker body 7. A fixing groove 30 is provided on the top of the base 1, and a dust cover 9 is clamped inside the fixing groove 30. The dual protection mechanism of the dust cover 9 and the filter 23 effectively blocks tiny dust particles from entering the interior of the speaker, further improving the dustproof ability of the smart speaker with adaptive noise reduction.

[0034] In specific implementation, an adaptive noise reduction smart speaker, when the smart speaker is performing noise reduction and dust prevention, first, when the smart speaker body 7 vibrates, the smart speaker body 7 will drive the mounting base 6 to vibrate, and because the outer side of the mounting base 6 is provided with a shock-absorbing airbag 19, the shock-absorbing airbag 19 first absorbs part of the vibration energy, and at the same time, the expanded sleeve airbag 27 forms an additional buffer layer inside the mounting base 6, further reducing the impact of vibration on the smart speaker body 7. In addition, when the sleeve airbag 27 is in an expanded state, it can further reduce the gap between the smart speaker body 7 and the mounting base 6, and at the same time, it can also effectively offset the gap caused by shaking, which helps to improve the noise reduction effect. Next, a layer of high-quality noise reduction cotton 21 is cleverly sleeved on the outer side of the smart speaker body 7, which makes full use of the sound absorption characteristics of the noise reduction cotton 21 material to effectively isolate external noise. At the same time, the selection of the noise reduction cotton 21 takes into account both sound absorption efficiency and air permeability, ensuring that while improving the sound quality, it does not affect the normal heat dissipation of the internal components of the speaker, further improving the noise reduction effect. In addition, because a filter 23 is provided on the outside of the noise reduction cotton 21, a dust cover 9 is snapped onto the outside of the smart speaker body 7, and the noise reduction cotton 21, the filter 23, and the dust cover 9 are all provided with a first sound outlet 31 and a second sound outlet 22 which are connected to the speaker 28, thereby effectively blocking tiny dust particles from entering the interior of the speaker and reducing the risk of failure caused by dust accumulation. At the same time, the first sound outlet 31 and the second sound outlet 22 will not hinder the transmission of sound from the smart speaker body 7. Secondly, when the smart speaker body 7 is not in use, the groove 34 is manually pulled to make the rotating cover 32 rotate inside the first sound outlet 31 through the rotating shaft 33, so as to close the first sound outlet 31, thereby further improving the dustproof effect. In this way, through the above operation, the dustproof ability of the adaptive noise reduction smart speaker is improved, and its adaptive noise reduction effect is guaranteed.

[0035] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
