Description

Technical Field

[0001] The invention belongs to the technical field of audio equipment, and in particular relates to a portable and detachable electronic speaker with a light. Background Art

[0002] An electronic speaker is a device that converts audio signals into sound. It is usually composed of a main cabinet or a subwoofer cabinet, a built-in power amplifier, and a digital signal processor. It can amplify and process the audio signals emitted by the digital signal processor and emit sound. The speaker is the terminal part of the entire audio system and is responsible for converting audio electrical energy into sound energy and radiating it into space.

[0003] The existing Chinese utility model patent with publication number CN209358719U has a fragrance diffuser installed at the bottom of the speaker body, and a fan installed inside the fragrance diffuser, a fragrance storage tank installed at the bottom of the fragrance diffuser, a fragrance absorption cavity installed in the middle of the fragrance storage tank, and a fragrance absorption layer installed inside the fragrance absorption cavity. The fragrance absorption layer can prevent the fragrance liquid from spilling, thereby increasing safety;

[0004] However, in actual use, this fragrance structure uses a fan as a pumping part to dissipate from the bottom to the top through the speaker body. The path is long and there is interference from the components inside the speaker, so the dissipation speed is slow. In outdoor usage scenarios, due to the existence of external natural wind, the fragrance coverage is small, the noise is large in the outdoor state, and the audio needs to be adjusted to a larger sound state. The overhead design of the speaker body will produce a larger resonance when the output volume is large. At the same time, the hourglass-shaped shape makes the speaker body only connected to the solid structure in the middle, and the other positions are suspended. Insufficient conduction leads to more serious resonance, and even overturning due to vibration when there is less fragrance liquid below. In view of this, a portable detachable electronic speaker with lights is provided. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a portable detachable electronic speaker with light.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] A portable detachable electronic speaker with light, comprising a box body and a speaker assembly, wherein the speaker assembly is fixed through the end of the box body, the speaker assembly comprises a woofer and a tweeter, and further comprises:

[0008] An inner box located at a side of the box body away from the speaker assembly, the inner box comprising an outer shell, a dissipation channel opening upward is provided in the middle of the outer shell, a light strip is installed at the end of the dissipation channel, an atomizer is installed at the bottom of the dissipation channel, and a side opening is opened in the outer shell directly facing the tweeter speaker;

[0009] A sound wave absorbing part extending through the side opening to the inner side of the escape channel, the sound wave absorbing part comprising an integration plate, the box body is provided with a treble channel at a position opposite to the direction of the treble speaker, the integration plate is provided with a semicircular treble fork in the treble channel facing the treble speaker, the box body is provided with a bass channel at a position opposite to the direction of the woofer speaker, the integration plate is provided with a bass fork in the bass channel facing the woofer speaker;

[0010] The shell has a deformation absorbing part installed opposite to the woofer, and the deformation absorbing part includes an airbag. The airbag is provided with a flexible section on the side opposite to the woofer. When the airbag is inflated, the flexible section can expand toward the woofer to drive the woofer fork to slide relative to the integration plate.

[0011] When used outdoors, the woofer and tweeter are arranged separately, and the sealed treble channel can increase the sound quality of the tweeter. The serpentine channel and the bass channel with an opening can increase the sound quality of the woofer, and the high tuning fork and the low tuning fork are installed on the back of the woofer and the tweeter to absorb the sound waves propagating backwards. The deformation absorption part can absorb more vibrations in the bass area and transmit them to the integration plate position, converting them into separate vibrations of the suspended integration plate, reducing the overall resonance of the speaker and improving the sound quality of the speaker. The atomizer introduces liquid fragrance into the escape channel and sprays it upward through the escape channel. The integration plate has large vibration energy, which will disturb the air inside the escape channel and improve the atomization effect. The high-energy vibration in the bass area will be converted into sliding friction, which can increase the temperature inside the escape channel and reduce the condensation and reflux phenomenon of the atomized liquid in the emission channel. When the atomized water vapor passes through the light strip position, the light strip is diffusely reflected to create a sound atmosphere, smell atmosphere and lighting atmosphere for camping.

[0012] Furthermore, the box body includes a mounting plate, a bearing plate and a top plate, the woofer and the tweeter are mounted in the middle of the mounting plate, the bearing plate is L-shaped, an opening is formed on the top plate corresponding to the escape channel, and two side panels are detachably mounted on both sides of the mounting plate, the bearing plate and the top plate.

[0013] Through the above technical scheme, a specific configuration of a box is disclosed, in which a mounting plate, a load-bearing plate and a top plate are surrounded to form a cylinder, and then side plates are installed at the openings on the left and right sides. The side plates are detachably connected and can be removed for replacement and maintenance of the internal structure, and can also be removed for internal cleaning, so as to adapt to dust cleaning operations after field use.

[0014] Furthermore, a partition plate 1 is provided in the middle of the box body, and the tweeter channel is formed by a combination of the top surface of the partition plate 1, the bottom surface of the top plate and the vertical side walls of the two side plates. A guide block is installed in the middle of the tweeter channel at a position equal to the height of the tweeter. The guide block is installed between the sound wave absorbing part and the tweeter in a suspended state.

[0015] Through the above technical scheme, in order to improve the purity of the treble, the guide block is suspended up and down, and the more regular sound waves in the middle will be rebounded for secondary use, while the sound waves with a larger divergence angle at the corners will produce multiple reflections at the corners to cause standing waves. It is more difficult to return to the original path after being bounced. The suspended design at the top and bottom ends of the guide block can continue to propagate backwards, and then be absorbed by the sound wave absorbing part and converted into vibration energy to prevent interference with the sound waves in the front, thereby reducing or eliminating unnecessary resonance and standing waves in the box 1, and preventing treble distortion caused by clutter.

[0016] Furthermore, the guide block is located at the center of the tuning fork, the side of the guide block facing the tweeter is set as an arc-shaped end face, the center of the arc-shaped end face is located at the tweeter, and the side of the guide block facing the tuning fork is provided with a sound absorbing surface.

[0017] Through the above technical scheme, in order to make the treble purer, the curved end surface of the guide block can rebound the sound waves radiating backwards from the middle of the tweeter, and superimpose them with the treble sound waves radiating forwards from the tweeter, while the sound-absorbing surface of the guide block will rebound the sound waves bounced back by the sound wave absorbing part backwards again to avoid interfering with the sound waves in front, so that the sound waves are transmitted from the front opening of the tweeter in a more uniform and consistent manner, thereby improving the uniformity and stability of the sound.

[0018] Furthermore, a secondary port is provided at the connection between the mounting plate and the supporting plate, a partition plate 2 is installed on the bottom surface of the inner box of the box body, a partition plate 3 is installed directly below the partition plate 1 of the box body, and the bass channel is constructed by the mounting plate, the supporting plate, the partition plate 1, the partition plate 2 and the partition plate 3 between the bass speaker and the secondary port.

[0019] Through the above technical scheme, the specific configuration of the bass channel position is disclosed, and the sub-port is located below the woofer, which redirects the sound waves behind the woofer and propagates them forward. When the low-frequency sound waves generated inside the speaker meet the sound waves propagated through the bass reflex tube, if their phases are the same or close, they will superimpose on each other, thereby increasing the amplitude of the low-frequency sound waves, making the bass deeper and more powerful.

[0020] Furthermore, the partition three is located at one-half of the space below the partition two, the supporting plate is provided with a semicircular end face block below the partition two, and a bass radiator is installed at the secondary port.

[0021] Through the above technical scheme, in order to improve the gain effect on bass, the position setting of partition three can form a serpentine channel with a constant diameter. The semicircular end face blocks make the corners smoother and reduce the resonance caused by standing waves at the corners. The bass radiator enhances the sound output of the speaker in the low frequency band, making the bass deeper and fuller.

[0022] Furthermore, the deformation absorbing part also includes a grille, the grille is located between the flexible section and the woofer, the bass fork is located in the middle of the grille notch, and the bass fork is fixedly connected to the outer wall of the flexible section.

[0023] Through the above technical solution, in order to increase the sound absorption effect of the deformation absorption part, the flexible section is divided into multiple sections through the grille. The flexible section can form a wavy shape after being inflated. The sound waves propagating backwards from the woofer are reflected by the wavy flexible section and change the angle. The vibration is reduced by offsetting each other, thereby reducing the bass resonance of the speaker. In the process, the vibration generated by the sound wave will be transmitted to the woofer fork, which can collect more energy.

[0024] Furthermore, an intake pipe group and an exhaust pipe group are installed through the end of the airbag, and electronic metering valves are installed in series on the intake pipe group and the exhaust pipe group. An air distribution pipe is installed at the outlet end of the exhaust pipe group, and the air distribution pipe is located at the bottom of the escape channel.

[0025] Through the above technical scheme, a specific inflation and deflation configuration of an airbag is provided, the air intake pipe group inflates the airbag to make the flexible section expand and extend out of the grille gap, and the exhaust pipe group deflates the airbag to make the flexible section return to the grille gap, the electronic metering valve can control the inflation and deflation speed difference, and is connected to the digital signal processor of the speaker through a wiring harness and a single-chip microcomputer, so that the inflation is accelerated when the volume is low and the airbag expands faster, the flexible section is greatly elongated, absorbs more sound waves, reduces the sound wave energy output from the bass channel, and prevents the bass of the woofer from being too heavy, and when the volume is low and the airbag is deflated, the inflation is reduced to shrink and return to the original position, the flexible section is slightly deformed, absorbs less sound waves, increases the sound wave energy output from the bass channel, and enhances the bass of the woofer, and the bass sound effect is better through the dynamic compensation of the airbag.

[0026] Furthermore, the bass fork and the integration plate are slidably connected to each other via a support plate and a sliding seat, a through sleeve is installed at the support plate corresponding to the airbag, the sliding seat is fixedly connected to the integration plate, the bass fork is fixedly connected to the support plate, and a through hole is opened at the support plate corresponding to the shell.

[0027] Through the above technical solution, in order to achieve the vibration amplification of the bass fork, the bass fork transmits the vibration to the integration plate position through the support plate and the sliding seat, and the sound wave impact absorbed by the airbag can also be transmitted to the support plate through the through sleeve, thereby driving the integration plate to oscillate more greatly, increasing the vibration intensity, and shattering the liquid fragrance condensed on the surface of the integration plate. It also generates heat through friction, thereby reducing the condensation of the atomized liquid fragrance in the escape channel.

[0028] Furthermore, a liner is installed in the outer shell in the escape channel, the liner is staggered with the integration plate, the integration plate is provided with teeth arranged up and down at the nozzle of the atomizer, a rubber sheet is installed between the side port and the escape channel, and the rubber sheet is provided with a notch that cooperates with the integration plate.

[0029] Through the above technical solution, in order to improve the atomization dispersion effect, multiple lining blocks disperse the escape channel into multiple independent channels, the number of nozzles of the atomizer is consistent with the number of independent channels, and multiple integration plates are set to disperse the liquid fragrance agent in contact with the atomized liquid. The integration plate has a large vibration amplitude due to the opening of the notch, which disturbs the atomized gas and shatters the liquid fragrance agent condensed on the integration plate, thereby further improving the atomization dispersion effect. The flexible structure of the rubber sheet avoids offsetting the vibration of the integration plate while preventing the liquid fragrance agent from escaping into the treble channel through the side port.

[0030] The beneficial effects of the present invention are as follows:

[0031] (1) The present invention forms a treble channel and a bass channel that are independent of each other on the back of the woofer and the tweeter respectively through the optimization of the box. The treble channel optimizes the corner positions that are prone to generating standing waves, and converts the noise waves propagating backward into independent vibrations of the sound wave absorbing part. The bass channel converts the bass sound waves propagating backward into independent vibrations of the sound wave absorbing part through the adaptive adjustment of the shape of the deformable absorbing part, thereby reducing the standing waves and resonance of the box.

[0032] (2) The present invention adopts the design of the deformation absorption part. The deformation absorption part adopts the inflation and deflation action of the airbag, which can cooperate with the grille to change the shape of the flexible section. Under different volume levels, the shape can be changed to adaptively absorb the bass sound waves propagating backward. During the reciprocating deformation, an upward airflow can be generated and the temperature of the integration plate can be increased, thereby assisting the diffusion of the atomized fragrance agent and improving the fragrance coverage.

[0033] (3) The present invention adopts the design of the inner box and the light strip. The escape channel in the inner box is used to emit the atomized fragrance agent, and the outlet of the escape channel is designed to be a long strip. With the long light strip installed at the outlet position, the air near the light strip can be changed by the atomized fragrance agent to form a strip-shaped mist curtain of gas-liquid mixture, so that the light emitted by the light strip is diffusely reflected, creating a sound atmosphere, a smell atmosphere and a light atmosphere.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] like Figure 1-Figure 10 As shown, this embodiment provides a portable detachable electronic speaker with light, including a box body 1 and a speaker assembly, the speaker assembly is fixed through the end of the box body 1, that is, installed on the vertical plane of the front end, the speaker assembly includes a woofer 2 and a tweeter 3, which emit bass and treble respectively, and the sound effect is better;

[0047] Regarding the inner box 4, the inner box 4 is located on the side of the box body 1 away from the speaker assembly. The inner box 4 includes a shell 41. A dissipation channel 42 with an opening upward is provided in the middle of the shell 41. A light strip 5 is installed at the end of the dissipation channel 42. An atomizer 45 is installed at the bottom of the dissipation channel 42. A receiving chamber 44 can be formed at the position of the atomizer 45. The receiving chamber 44 opens upward and is installed with a cover plate for accommodating fragrance waiting to be atomized. The atomizer 45 can also be directly connected to the atomizer 45 through a pipeline. The atomizer 45 provides fragrance through a pump. The shell 41 is provided with a side opening 47 facing the tweeter 3. The side opening 47 is arranged forward to form an installation space.

[0048] Regarding the sound wave absorbing part 7, the sound wave absorbing part 7 extends through the side opening 47 to the inside of the escape channel 42, and the sound wave absorbing part 7 includes an integration plate 73, and a support 71 is installed in the middle of the integration plate 73. The support 71 is made of rubber material to prevent the integration plate 73 from being completely fixed and causing the failure to vibrate and release the potential energy of the sound wave. The box body 1 is constructed with a tweeter channel 8 at the opposite position to the tweeter 3. The sound wave absorbing part 7 extends into the tweeter channel 8, and the integration plate 73 is installed with a semicircular high pitch fork 7 at the position of the tweeter 3 in the tweeter channel 8. 2. The treble tuning fork 72 is used to contact the sound waves inside the treble channel 8 and convert them into vibrations of the integration board 73. The box 1 is constructed with a bass channel 9 at a position opposite to the woofer 2. The integration board 73 is installed with a bass fork 75 at a position in the bass channel 9 facing the woofer 2. The bass fork 75 is used to contact the sound waves inside the bass channel 9 and also convert them into vibrations of the integration board 73. By centrally guiding the internal sound wave energy and converting it into a separate vibration of the integration board 73, the resonance of the box 1 caused by the sound waves can be reduced and the sound quality can be improved.

[0049] Regarding the deformation absorbing part 6, the deformation absorbing part 6 is installed at a position directly opposite to the woofer 2. The deformation absorbing part 6 includes an airbag 61. The airbag 61 is located outside the front side of the inner box 4 and directly located in the bass channel 9. It can absorb the sound wave energy of the woofer 2 to the rear long wave. A flexible section 611 is provided on the side of the airbag 61 facing the woofer 2. The flexible section 611 can produce elastic deformation. When the airbag 61 is inflated, the flexible section 611 can be deformed and expand toward the woofer 2, driving the bass fork 75 to slide relative to the integration plate 73. This sliding can generate sliding friction heat, and can also change the shape of the vertical side wall at the position directly opposite to the rear end of the woofer 2, thereby reducing the number of sound waves directly rebounding back to the position of the woofer 2 and reducing the influence of rebound noise on the woofer 2.

[0050] In a further embodiment, a specific configuration of a box body 1 is disclosed, wherein the box body 1 comprises a mounting plate 11, a carrying plate 12 and a top plate 13, wherein a handle 19 is provided on the top of the top plate 13 for easy transportation and carrying when going out, wherein the woofer 2 and the tweeter 3 are assembled in the middle of the mounting plate 11, and the woofer 2 and the tweeter 3 are arranged one below the other, wherein the carrying plate 12 is L-shaped, and rubber feet are installed at the bottom for anti-slip placement, wherein the mounting plate 11, the carrying plate 12 and the top plate 13 are surrounded to form a cylinder, and an opening is formed on the top plate 13 corresponding to the escape channel 42 to ensure that the fragrance agent escapes upward smoothly, and two side panels 14 are detachably installed on both sides of the mounting plate 11, the carrying plate 12 and the top plate 13, and the side panels 14 installed at the opening positions on the left and right sides are connected by bolts or a detachable structure, and the side panels 14 are detachably connected and can be removed for replacement and maintenance of the internal structure, and can also be cleaned internally to adapt to dust cleaning operations after field use.

[0051] In a further embodiment, in order to improve the purity of the treble, the treble channel 8 is designed, referring to Figure 3 and Figure 4 A partition 15 is provided in the middle of the box 1, and the treble channel 8 is formed by the top surface of the partition 15, the bottom surface of the top plate 13 and the vertical side walls of the two side plates 14, so as to form a relatively sealed cavity, which can collect the sound waves diverging backwards from the tweeter 3, and a guide block 18 is installed in the middle of the treble channel 8 at a position equal to the height of the tweeter 3. The guide block 18 is installed between the sound wave absorbing part 7 and the tweeter 3 in an up-and-down suspended state, that is, the guide block 18 is in an up-and-down suspended state, and the more regular sound waves in the middle will be rebounded for secondary utilization, while the sound waves with a larger divergence angle at the corners will generate multiple reflections at the corners to cause standing waves, and it is more difficult to return to the original path after being bounced. The suspended design at the top and bottom ends of the guide block 18 can continue to propagate backwards, and then be absorbed by the sound wave absorbing part 7 and converted into vibration energy, so as to prevent interference with the sound waves in the front, reduce or eliminate unnecessary resonance and standing waves in the box 1, and prevent treble distortion caused by clutter.

[0052] In a further embodiment, in order to make the treble purer, the structure of the treble tuning fork 72 is further optimized, referring to Figure 5 and Figure 6 The high tuning fork 72 is semicircular in shape, and the notch faces forward. The guide block 18 is located at the center of the high tuning fork 72. A sound-absorbing surface is provided on the side of the guide block 18 facing the high tuning fork 72. Specifically, the sound-absorbing surface can be a sound-absorbing material coated on the outer wall of the guide block 18. The sound-absorbing surface can also be a special wavy sound-absorbing shape. Moreover, the sound-absorbing surface of the guide block 18 will bounce the sound waves bounced back by the sound wave absorbing part 7 backward again to avoid interfering with the sound waves in front, and can also fully transfer the energy of these sound waves to the high tuning fork 72. The cross-section of the high tuning fork 72 is a "^" shape with the tip facing forward, which can separate the sound waves left and right. Side strips 721 are installed on the left and right sides of the high tuning fork 72 to increase the surface area and fully contact the sound waves, and a through hole 723 is opened on the high tuning fork 72 to integrate The upper part of the plate 73 is narrowed to form a joint 731, and a support ear 722 is designed to be spaced between the treble tuning fork 72 and the joint 731 to reduce the weight of the treble tuning fork 72 and reduce the integrity of the treble tuning fork 72, so that the treble tuning fork 72 is more likely to vibrate in high-frequency sound waves, and absorb the energy of high-frequency sound waves and convert them into vibrations of the integration plate 73. At the same time, the guide block 18 is set to an arc-shaped end face on the side facing the tweeter 3, and the center of the arc-shaped end face is located at the tweeter 3. The arc-shaped end face of the guide block 18 can rebound the sound waves radiating backward from the middle part of the tweeter 3, and superimpose them with the treble sound waves radiating forward from the tweeter 3, so that the sound energy of the treble is larger and more unified, so that the sound waves are transmitted from the front opening of the tweeter 3 in a more uniform and consistent manner, thereby improving the treble sound effect.

[0053] In a further embodiment, a specific configuration of the position of the bass channel 9 is disclosed, referring to Figure 4 A sub-port 91 is provided at the connection between the mounting plate 11 and the bearing plate 12. The sub-port 91 is located below the woofer 2 to redirect the sound waves behind the woofer 2 and propagate forward. The box 1 is provided with a partition 2 16 on the bottom surface of the inner box 4. The box 1 is provided with a partition 3 17 directly below the partition 1 15. The bass channel 9 is constructed by the mounting plate 11, the bearing plate 12, the partition 1 15, the partition 2 16 and the partition 3 17 between the woofer 2 and the sub-port 91. When the low-frequency sound waves generated inside the speaker meet the sound waves propagated through the bass reflex tube, the design of the path distance of the bass channel 9 and the position of the sub-port 91 makes their phases the same or close, and they will superimpose on each other, thereby increasing the amplitude of the low-frequency sound waves, making the bass deeper and more powerful.

[0054] In a further embodiment, in order to improve the gain effect on bass, refer to Figure 4The partition three 17 is located at the half position of the space below the partition two 16. The position setting of the partition three 17 can form a serpentine channel with a constant diameter. The supporting plate 12 is provided with a semicircular end face block below the partition two 16. The semicircular end face block makes the corner position smoother and reduces the resonance caused by standing waves at the corner position. A bass radiator is installed at the sub-port 91. The bass radiator enhances the sound output of the speaker in the low frequency band, making the bass deeper and fuller.

[0055] In a further embodiment, in order to increase the sound absorption effect of the deformation absorbing portion 6, refer to Figure 5 The deformation absorbing part 6 further includes a grille 62, the grille 62 has gaps arranged left and right, the grille 62 is located between the flexible section 611 and the woofer 2, and the flexible section 611 is divided into multiple sections by the grille 62. After the flexible section 611 is inflated, Fig.10 , will extend forward through the gap, while the second part is blocked by the grille 62 and cannot extend, thus forming a wavy shape. The sound waves propagating backward from the woofer 2 are reflected by the wavy flexible section 611 and change the angle, and reduce the vibration by offsetting each other, and are finally transmitted to the bass fork 75 and the deformation absorbing part 6, and are converted into the vibration of the bass fork 75 and the oscillation friction and heat of the air in the deformation absorbing part 6, thereby reducing the bass resonance of the overall cylindrical structure of the sound box. The bass fork 75 is located in the middle of the gap of the grille 62, and the bass fork 75 is fixedly connected to the outer wall of the flexible section 611. During the process, the vibration generated by the sound wave will be transmitted to the bass fork 75, and the integration plate 73 can collect more sound wave vibration energy through the bass fork 75.

[0056] In a further embodiment, a specific inflation and deflation configuration of the airbag 61 is provided, referring to Figure 8The end of the airbag 61 is penetrated by an air intake pipe group 63 and an exhaust pipe group 65. The air intake pipe group 63 is connected to an air pump or other air pumping device to inflate the airbag 61, so that the flexible section 611 expands and extends out of the notch of the grille 62. The exhaust pipe group 65 deflates the airbag 61, so that the flexible section 611 is reset and retracted into the notch of the grille 62. An electronic metering valve 66 is installed in series on the air intake pipe group 63 and the exhaust pipe group 65. The electronic metering valve 66 can control the difference in filling and discharging speed, and is connected to the digital signal processor of the speaker through a wiring harness and a single-chip microcomputer. When the bass volume is large, the inflation is accelerated to accelerate the expansion of the airbag 61. The flexible section 611 is greatly elongated, absorbs more sound waves, and reduces the sound wave energy output from the bass channel 9, preventing To prevent the bass of the subwoofer 2 from being too heavy, the inflation is reduced at low volume to shrink and reset the airbag 61. The deformation degree of the flexible section 611 is small, and less sound waves are absorbed, which increases the sound wave energy output from the bass channel 9, enhances the bass of the subwoofer 2, and makes the bass sound better through the dynamic compensation of the airbag 61. An air distribution pipe 64 is installed at the outlet end of the exhaust pipe group 65. The air distribution pipe 64 is located at the bottom of the escape channel 42. The exhausted gas can participate in the atomization and escape of the fragrance. The atomized fragrance is discharged more quickly through the airflow from bottom to top, which improves the efficiency. The air vibrated by the bass sound wave will carry heat due to its own friction, thereby optimizing the atomization environment of the fragrance and making the fragrance of the fragrance escape over a larger range.

[0057] In a further embodiment, in order to realize the vibration amplification of the bass fork 75, referring to Fig. 9 The bass fork 75 and the integration plate 73 are slidably connected to each other through the support plate 74 and the sliding seat 76. The airbag 61 is installed with a through sleeve 612 at the support plate 74 corresponding to the airbag 61. The sliding seat 76 is fixedly connected to the integration plate 73. The bass fork 75 is fixedly connected to the support plate 74. When the airbag 61 is inflated and deflated, it will drive the bass fork 75 to slide back and forth. The support plate 74 and the sliding seat 76 reciprocate to generate heat, which is transferred to the integration plate 73 to heat it up, reducing the condensation of the atomized liquid fragrance in the escape channel 42, and spraying it upward in a mist. The bass fork 75 passes through the support plate 74. The plate 74 and the sliding seat 76 transmit the vibration to the position of the integration plate 73. The sound wave impact absorbed by the airbag 61 can also be transmitted to the support plate 74 through the through sleeve 612, thereby driving the integration plate 73 to oscillate more significantly and improving the vibration intensity. A through hole 411 is opened at the corresponding support plate 74 of the shell 41. The size of the through hole 411 is larger than that of the support plate 74, providing a space for the support plate 74 to fully vibrate, so that the vibration of the bass fork 75 can be smoothly transmitted to the position of the integration plate 73, that is, the liquid fragrance condensed on the surface of the integration plate 73 is shattered.

[0058] In a further embodiment, in order to improve the atomization dispersion effect, the structure of the escape channel 42 is optimized, referring to Figure 7The housing 41 is provided with a lining block 46 in the dissipation channel 42. The lining block 46 and the integration plate 73 are arranged in a staggered manner. The plurality of lining blocks 46 disperse the dissipation channel 42 into a plurality of independent channels. The number of nozzles of the atomizer 45 is consistent with the number of independent channels. In addition, a plurality of integration plates 73 are provided to disperse the liquid fragrance agent in contact with the atomization, so that the fragrance has more dissipation paths and is evenly dispersed in a rectangular space to form a strip-shaped mist curtain. When matched with the light strip 5, a light strip in a flowing state can be formed, and the decorative effect is better. The integration plate 73 is directly opposite to the nozzle of the atomizer 45. The integrated plate 73 is provided with teeth openings 732 arranged up and down. The integrated plate 73 has a large vibration amplitude due to the teeth openings 732, which disturbs the atomized gas and breaks up the liquid fragrance agent condensed on the integrated plate 73, thereby further improving the atomization dispersion effect. A rubber sheet 43 is installed between the side opening 47 and the escape channel 42. The flexible structure of the rubber sheet 43 can avoid offsetting the vibration of the integrated plate 73 while preventing the liquid fragrance agent from escaping into the treble channel 8 through the side opening 47. The rubber sheet 43 is provided with a notch that cooperates with the integrated plate 73, so that the integrated plate 73 can be smoothly installed while dividing the space.

[0059] The working principle of this embodiment is as follows:

[0060] When in use, the woofer 2 and the tweeter 3 are arranged separately, the sealed treble channel 8 can improve the sound quality of the tweeter 3, the serpentine channel and the bass channel 9 with an opening can improve the sound quality of the woofer 2, and the high tuning fork 72 and the low tuning fork 75 are installed at the back of the woofer 2 and the tweeter 3 to absorb the sound waves propagating backwards, and the deformation absorption part 6 can absorb more vibrations in the bass area and transmit them to the position of the integration plate 73, which is converted into a separate vibration of the suspension integration plate 73, thereby reducing the overall resonance of the sound box and improving the sound quality of the sound box;

[0061] If used in a noisy outdoor environment, the inflation amount of the deformation absorbing part 6 can be adjusted to make the ability of the bass fork 75 to absorb sound waves change in an adjustable manner, and then the single-chip microcomputer can receive the audio signal of the digital signal processor according to the volume of the bass, and generate different control signals accordingly to change the output of the bass, provide better sound quality, and improve the user experience. For example, when conducting outdoor live broadcasts, a higher-definition accompaniment can be provided to increase the live broadcast effect;

[0062] If used in scenes such as camping, the atomizer 45 can be used to introduce liquid fragrance into the dissipation channel 42, and spray it upward through the dissipation channel 42, so that the surrounding environment is more shareable, and there is no need to carry a separate fragrance machine. It is more practical in scenes such as camping where equipment needs to be carried. At the same time, the integration plate 73 has a large vibration energy, which will disturb the air inside the dissipation channel 42. The high-energy vibration in the bass area will be converted into sliding friction, which can increase the temperature inside the dissipation channel 42, reduce the condensation and reflux phenomenon of the atomized liquid in the dissipation channel, and improve the atomization effect;

[0063] In a low-brightness environment, when the atomized water vapor passes through the position of the light strip 5, the atomized droplets in the air will cause diffuse reflection of the light emitted upward by the light strip 5. Compared with the single luminous light strip 5, a more suitable camping sound atmosphere, smell atmosphere and lighting atmosphere can be created.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
