Description

Technical Field

[0001] The invention relates to the technical field of audio equipment, and in particular provides an outdoor portable audio system. Background Art

[0002] An outdoor portable speaker is a sound playback device that is easy to carry and can be used outdoors. It is small in size, can be connected wirelessly, and can store electricity after being charged. It is widely used in outdoor activity venues.

[0003] An invention patent with application number CN202311249902.4 discloses an outdoor portable speaker, which can increase the height of the speaker body, which is conducive to the sound of the speaker being spread farther. By installing an inflatable structure and a diagonal brace structure, the inflatable structure can drive the diagonal brace structure to unfold when the speaker body rises, and the diagonal brace rod rotates and unfolds to support the speaker body, which can increase the contact area between the speaker body and the ground, thereby increasing the height of the speaker body while enhancing the stability of the speaker body during use.

[0004] However, there are still some shortcomings in the specific use of the above-mentioned speakers: since most existing speakers adjust the volume by using a volume adjustment knob on the speakers, and if the volume of the above-mentioned speakers is adjusted to the maximum state during outdoor use, then when the speakers are used, the volume is not turned down in time. When the speakers are turned on for the next time, since the components of the speakers have not yet gone through the preheating stage, the high volume will cause them to work at full capacity instantly, causing damage to the components. This will cause some fragile internal audio components to fail in the long run, thereby causing damage to the sound-generating components of the speakers, and further reducing the service life of the speakers. However, the above-mentioned outdoor speakers cannot achieve the effect of automatically turning down the volume when the speakers are turned off.

[0037] The present invention will be further described below in conjunction with the embodiments.

[0038] Embodiment 1: Figures 1 to 6 As shown, an outdoor portable speaker includes a speaker body 1, wherein a master controller is disposed inside the speaker body 1 for controlling the start and shut down of the speaker body 1. A volume knob 11 is disposed on one side of the top surface of the speaker body 1, and the volume knob 11 is used to adjust the volume of the speaker body 1. Initially, the volume knob 11 is in a low volume position, referring to Figure 5 The volume knob 11 is rotated clockwise to increase the volume, and is rotated counterclockwise to decrease the volume. When the volume is at zero, the volume knob 11 cannot be rotated counterclockwise. Two sound speakers 12 are symmetrically arranged on one side of the speaker body 1, and four supporting feet 13 are evenly and fixedly arranged on the bottom of the speaker body 1.

[0039] An adjustment protection mechanism is provided on one side of the sound body 1 close to the sound speaker 12. The adjustment protection mechanism includes two protection covers 21 fixedly connected to the sound body 1 and corresponding to the positions of the two sound speakers 12. Two electric slide rails 22 are symmetrically fixedly installed on the surface of one side of the sound body 1 close to the sound speaker 12. Electric sliders 23 are slidably connected to the two electric slide rails 22. Initially, the two electric sliders 23 are located on the side close to each other (i.e. Figure 4The two electric slide rails 22 and the corresponding electric sliders 23 are controlled by a built-in controller, which is installed inside the audio body 1 and is electrically connected to the main controller of the audio body 1. When the audio body 1 is started, the two electric slide rails 22 are controlled by the built-in controller to start, driving the two electric sliders 23 to move horizontally away to the final position; and when the audio body 1 is closed after use, the built-in controller controls the electric slide rails 22 to drive the two electric sliders 23 to move to the side close to each other and reset. The surface of the two electric sliders 23 on the side away from the audio body 1 is fixedly connected with a displacement plate 24, and the ends of the two displacement plates 24 away from the electric sliders 23 are fixedly connected with a sealing disc 25. The protective cover 21 and the sealing disc 25 are both made of transparent acrylic material. The transparent acrylic material is light in weight, which is convenient for users to carry the audio. A sealing ring is provided on the surface of the side where the sealing disc 25 fits the protective cover 21. When the two cooperate to seal, the sealing between the two is improved. The two sealing discs 25 are initially fitted with the surfaces of the two protective covers 21 on the side away from the audio body 1, and an L-shaped plate 26 is fixedly connected to the top surface of the electric slider 23 on the side close to the volume knob 11. A plurality of concave plates 27 are evenly fixedly connected to the surface of the L-shaped plate 26 on the side close to the volume knob 11, and each concave plate 27 is rotatably connected to a pawl 28. A torsion spring 29 is connected to the portion where the pawl 28 is rotatably connected to the concave plate 27, and one end of the torsion spring 29 is fixedly connected to the concave plate 27, and the other end is fixedly connected to the pawl 28. A gear 210 is rotatably connected to one side of the top surface of the audio body 1 close to the pawl 28, and the gear 210 is located on the path of horizontal movement of the pawl 28. A gear ring 211 is rotatably connected to the position on the upper surface of the audio body 1 corresponding to the volume knob 11, and the gear ring 211 and the gear 210 are meshed with each other. A plurality of card plates 214 are evenly arranged on the inner ring surface of the gear ring 211, and a plurality of empty grooves 212 are evenly arranged on the outer wall of the volume knob 11. An empty groove 212 is correspondingly arranged between every two adjacent card plates 214, and a torsion spring plate 213 is rotatably connected in each empty groove 212. A torsion spring 1 is connected between the torsion spring plate 213 and the groove surface of the adjacent empty groove 212, and one end of the torsion spring 1 is fixedly connected to the groove surface of the empty groove 212, and the other end is fixedly connected to the torsion spring plate 213.

[0040] Furthermore, if Figure 3 , Figure 7As shown, a fixed box body 221 is fixedly connected to the position corresponding to the electric slide rail 22 of the sound body 1, and a moving box body 222 is inserted above the fixed box body 221. The two electric slide rails 22 are located between the fixed box body 221 and the moving box body 222. The fixed box body 221 and the moving box body 222 are both provided with horizontal grooves for the horizontal displacement of two displacement plates 24, and the two displacement plates 24 pass through the horizontal grooves. The moving box body 222 is provided with a straight groove for the horizontal sliding displacement of an L-shaped plate 26, and the L-shaped plate 26 passes through the straight grooves. Specifically, soft brushes are provided on the horizontal grooves and the straight grooves to reduce external dust from entering the fixed box body 221 and the moving box body 222 from the horizontal grooves and the straight grooves. When in use: When used outdoors, the electric slide rail 22 and the electric slider 23 are always located between the fixed box body 221 and the movable box body 222, thereby reducing the adhesion of outdoor impurities and dust to the electric slide rail 22 and the electric slider 23, thereby reducing the impact of dust and impurities on the transmission of the two, thereby ensuring the stability of the transmission of the two.

[0041] Furthermore, if Figure 3 As shown, two plug blocks 223 are symmetrically fixedly connected to the surface of the movable box body 222 away from the sound body 1, and a groove block 224 is fixedly connected to the position corresponding to the two plug blocks 223 on the fixed box body 221, and the two plug blocks 223 are tightly inserted in the corresponding groove blocks 224.

[0042] During use: the user places the audio body 1 on a tabletop outdoors so that the four support legs 13 are in contact with the tabletop to ensure the stability of the audio body 1 during use. When the user starts the audio body 1, the built-in controller will start the two electric slide rails 22, thereby driving the two electric sliders 23 to move horizontally away from each other, and then the two displacement plates 24 and the two sealing discs 25 are driven to move synchronously through the horizontal movement of the electric sliders 23. At the same time, as the two electric sliders 23 move horizontally away from each other, one of the electric sliders 23 will also drive the L-shaped plate 26 and the ratchet 28 to move synchronously. During this process, the ratchet 28 contacts the teeth of the gear 210, thereby causing the ratchet 28 to rotate. During this process, the torsion spring 29 is in a stressed and deformed state. During this process, the ratchet 28 will not drive the gear 210 to rotate, so the gear 210 and the gear ring 211 will not rotate, and then the volume knob 11 will not rotate. When the two electric sliders 23 move to the final position, the pawl 28 on the L-shaped plate 26 will not conflict with the gear 210, thereby not affecting the free rotation of the gear 210 and the gear ring 211. Therefore, the user can still freely rotate the volume knob 11 to adjust the volume while using the audio body 1.

[0043] When the user finishes using the sound main body 1, the two electric slide rails 22 start to drive the corresponding two electric slide blocks 23 to reset horizontally in the opposite direction, thereby driving the two sealing discs 25 to reset in the opposite direction, that is, to move to fit with the two protective covers 21 again. Therefore, when the sound main body 1 is used up, the two protective covers 21 and the two sealing discs 25 can automatically and timely protect the sound speaker 12 to reduce external dust adhering to the sound speaker 12 when the sound main body 1 is not in use. At the same time, the protective cover 21 and the sealing disc 25 can also prevent the sound speaker 12 from being accidentally damaged when not in use, so as to improve the safety of the sound main body 1 after use.

[0044] During the process of the two electric sliders 23 being reset in the opposite direction and horizontally, when one of the pawls 28 moves to contact the gear 210, the pawl 28 cannot rotate under the blocking effect of the concave plate 27. As a result, as the multiple pawls 28 contact the gear 210 one by one, the gear 210 will be driven to rotate clockwise, thereby driving the gear ring 211 to rotate counterclockwise through the gear 210, and then the card plate 214 on the inner ring surface of the gear ring 211 will contact the torsion spring plate 213, thereby driving the volume knob 11 to automatically rotate counterclockwise. As the volume knob 11 rotates counterclockwise, the volume of the audio body 1 will be turned down. If the user turns the volume knob 11 to adjust the volume by a small amplitude when using the audio body 1, the volume can be adjusted to a mute state by turning the volume knob 11 as the electric slider 23 drives the pawl 28 to reset and move. Subsequently, if the volume knob 11 is closed and cannot continue to rotate counterclockwise, and the card plate 214 continues to move with the rotation of the toothed ring 211, the card plate 214 will continue to resist the torsion spring plate 213, and cause the torsion spring of the torsion spring plate 213 to deform under force, thereby causing the torsion spring plate 213 to rotate in the direction of the slot surface of the empty slot 212, until the card plate 214 rotates to pass over the adjacent torsion spring plate 213, that is, during this process, the toothed ring 211 is in an idling state, and will not drive the volume knob 11 to continue to rotate counterclockwise, thereby not affecting the resetting of the pawl 28 and other components. Note: The rotation direction reference in the above process is only for reference Figure 5 Therefore, through the cooperation of the gear 210 and the gear ring 211 and other components, after the use of the sound body 1 is finished, no matter how much the user turns the volume knob 11 clockwise to increase the volume of the sound body 1, after use, the rotation of the gear ring 211 will drive the volume knob 11 to rotate counterclockwise, thereby avoiding the sound body 1 being in the maximum state when the volume is turned off. Therefore, when the sound body 1 is turned on and used next time, the sound-generating elements inside the sound body 1 will not be suddenly in the full-load state, which is beneficial to protecting the sound-generating elements inside the sound body 1 and prolonging the service life of the sound body 1.

[0045] Embodiment 2: Figure 1 , Figure 2 as well as Figures 7 to 9 As shown, an outdoor portable audio system further includes a matching processing mechanism disposed on one side of the audio system main body 1, the matching processing mechanism includes a spiral rod 32 rotatably connected to the surface of the audio system main body 1 on one side close to the sound speaker 12, the spiral rod 32 is located above the electric slide rail 22, and is also located between the fixed box body 221 and the moving box body 222, specifically, the end of the spiral rod 32 away from the displacement plate 24 passes through the moving box body 222, and the moving box body 222 is provided with a U-shaped hole for the spiral rod 32 to pass through. A collar 31 is sleeved on the spiral rod 32, a piston cylinder 37 is fixedly mounted on the surface of one side of the audio system main body 1, the bottom of the collar 31 is fixedly connected to the displacement plate 24 close to the side of the piston cylinder 37, a spiral groove is provided on the outer ring surface of the spiral rod 32, and a protrusion 33 sliding in the spiral groove is provided on the inner ring surface of the collar 31, the protrusion 33 is hemispherical, and the outer surface of the protrusion 33 and the groove surface of the spiral groove are both smooth surfaces. The spiral rod 32 and the spiral groove are both located between the fixed box body 221 and the movable box body 222 , which can also reduce the adhesion of external dust and impurities in the spiral groove during outdoor use, thereby avoiding affecting the transmission effect between the spiral groove and the protrusion 33 . The end of the spiral rod 32 close to the piston cylinder 37 is fixedly connected to the coaxial disk 34, and the side surface of the coaxial disk 34 away from the spiral rod 32 is rotatably connected to the short rod 35, the axis of the short rod 35 is not colinear with the axis of the spiral rod 32, and the end of the short rod 35 away from the coaxial disk 34 is rotatably connected to the long rod 36, and a piston rod 38 is inserted into the interior of the piston cylinder 37. The piston rod 38 includes a rod body and a piston, wherein the piston and the piston cylinder 37 are slidably matched, the rod body of the piston rod 38 extends to the outside of the piston cylinder 37 and is rotatably connected to the long rod 36, and the end of the piston cylinder 37 away from the long rod 36 is connected to a suction pipe 39, and a one-way intake valve is installed at the portion where the suction pipe 39 is connected to the piston cylinder 37, and the end of the suction pipe 39 away from the piston cylinder 37 is connected to a suction ring pipe 310, and two suction ring pipes 310 are provided, and the positions of the two suction ring pipes 310 correspond to the two sound speakers 12, and the two suction ring pipes 310 are connected to each other. A plurality of suction nozzles 311 are evenly connected and arranged on the suction ring tube 310, and the plurality of suction nozzles 311 on the same suction ring tube 310 are distributed in an annular shape on the inner annular surface of the adjacent protective cover 21. The plurality of suction nozzles 311 all pass through the adjacent protective cover 21, and a discharge pipe 312 is connected and arranged at the bottom of the piston cylinder 37 away from the long rod 36, and a one-way air outlet valve is installed at the portion where the discharge pipe 312 is connected to the piston cylinder 37.

[0046] During use: Considering that the sound body 1 is used outdoors, when the two sealing discs 25 are horizontally displaced away from the two sound speakers 12, dust and impurities will adhere to the surface of the two sound speakers 12 during outdoor use. As the two electric sliders 23 drive the two displacement plates 24 to move horizontally closer or farther away, the sleeve ring 31 will also be driven to move synchronously, and as the sleeve ring 31 moves horizontally back and forth, the protrusion 33 will contact and squeeze the spiral groove on the outer ring surface of the spiral rod 32, thereby driving the spiral rod 32 to rotate. As the spiral rod 32 rotates, the coaxial disc 34 will be driven to rotate synchronously, and the coaxial disc 34 will then drive the short rod 35 to rotate, thereby driving the piston rod 38 to reciprocate horizontally inside the piston cylinder 37 through the short rod 35 and the long rod 36. When the piston rod 38 moves horizontally toward the coaxial disk 34, the one-way air inlet valve at the connection point between the suction pipe 39 and the piston cylinder 37 opens, so that dust and impurities attached to the two sounding speakers 12 are automatically sucked into the interior of the piston cylinder 37 through the suction pipe 39, the suction ring tube 310 and the suction nozzle 311. When the piston rod 38 moves horizontally toward the direction away from the coaxial disk 34, the one-way air outlet valve at the connection point between the discharge pipe 312 and the piston cylinder 37 opens, so that the dust and impurities collected in the piston cylinder 37 are discharged outward through the discharge pipe 312 to avoid dust and impurities remaining in the piston cylinder 37. Therefore, through the cooperation of the piston cylinder 37, the suction nozzle 311 and other components, the residual dust and impurities attached to the sound speaker 12 are collected and processed before and after the use of the sound main body 1, and the collected dust and impurities can be automatically discharged, reducing the steps of manual processing. Therefore, after the sound main body 1 is used outdoors, the dust and impurities attached to the sound speaker 12 can be reduced, and the dust and impurities are prevented from being attached to the sound speaker 12 for a long time and affecting the sound effect of the sound speaker 12. By using two interconnected suction ring tubes 310 and multiple suction nozzles 311 distributed in an annular shape on the inner annular surface of the adjacent protective cover 21, the suction nozzles 311 distributed in an annular shape increase the collection surface of dust and impurities, so as to improve the collection effect of dust and impurities attached to the sound speaker 12, and further reduce the dust and impurities attached to the sound speaker 12.

[0047] Embodiment 3: Figure 1 , Fig.10 , Fig.11As shown, an outdoor portable speaker also includes a stabilizing component arranged on a supporting leg 13, the stabilizing component includes an open cabin 41 opened in the middle of the supporting leg 13, a through vertical slot 4101 is opened at a position corresponding to the supporting leg 13 and the open cabin 41, a lifting plate 43 is slidably connected to the through vertical slot 4101, a ground cone 44 is fixedly connected to one side of the lifting plate 43 located inside the open cabin 41, the ground cone 44 is initially located inside the open cabin 41, and the ground cone 44 is a quadrilateral cone shape. A magnet sheet 42 is fixedly connected to a position corresponding to the supporting leg 13 and the lifting plate 43, and the magnet sheet 42 is magnetically connected to the lifting plate 43.

[0048] When in use: Considering that the sound body 1 needs to be placed on the muddy ground when used outdoors, and the stability of the sound body 1 placed on the muddy ground is poor. Then, when the user needs to place the sound body 1 on the muddy ground, the user can hold the lifting plates 43 one by one and apply downward external force to them to separate the lifting plates 43 from the magnet sheet 42, and then continue to apply downward external force to the lifting plates 43 to drive the ground cones 44 to move downward from the inside of the opening cabin 41, and finally cause the ground cones 44 to be inserted into the mud, so that each ground cone 44 is inserted downward into the mud. Therefore, when the audio body 1 is placed on the outdoor dirt ground, the four ground cones 44 are inserted into the soil to improve the stability of the audio body 1 on the dirt ground and prevent the audio body 1 from tipping over during use, thereby improving the adaptability and stability of the audio body 1 for outdoor use. When not in use, the four ground cones 44 are fixed by magnetic attraction through the lifting plate 43 and the magnet sheet 42, which can also prevent the ground cones 44 from accidentally moving out of the opening cabin 41 when not in use and being accidentally touched by the user, thereby preventing the ground cones 44 from scratching the user.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
