Description

Technical Field

[0001] The invention relates to the technical field of outdoor speakers, in particular to a large outdoor speaker. Background Art

[0002] Large outdoor speakers are a type of audio equipment specially designed for outdoor environments. They are usually fixed outdoors, such as parks, squares or stadiums, which are generally open-air.

[0003] Generally, outdoor speakers are waterproof, and their waterproofness is mainly achieved by seals, waterproof coatings and other structures. However, they perform poorly in rainstorms with heavy rainfall. This is because existing large outdoor speakers mainly rely on the small holes on the sound grilles to transmit sound to the outside world. Despite the waterproof design, under the continuous impact of heavy rain and the invasion of large amounts of rain, the outdoor speakers are fixed and cannot be moved, and the sound grilles will become a channel for rainwater to penetrate into the speakers, which will damage key components such as speakers and circuits inside the speakers, causing the speakers to malfunction or even fail to work properly. In addition, rainwater usually contains certain impurities and corrosive components. Long-term contact with the sound grilles and internal components of the speakers will cause problems such as rust on metal parts and aging of plastic parts, reducing the service life of the speakers.

[0004] Therefore, a large outdoor speaker is proposed. Summary of the invention

[0008] Furthermore, it also includes a scraping assembly arranged on the outdoor speaker, the scraping assembly is used to scrape dust on the side of the sound grille away from the outdoor speaker, the scraping assembly includes two long-rod pulleys, the two long-rod pulleys are symmetrically connected to the inner wall of the casing and rotate symmetrically in an upper and lower distribution, the two long-rod pulleys are symmetrically connected to two belts 1 through the pulleys, a rubber scraper is fixedly connected between the outer surfaces of the two belts 1, the end of the long-rod pulley at the top close to the rain sensor passes through the casing, the end of the long-rod pulley at the top that passes through the casing is fixedly connected to a short-handled pulley, the short-handled pulley and the long-handled bevel gear are connected with a belt 2 through the pulley transmission, and a water baffle is fixedly connected to the outdoor speaker and the outer wall of the casing.

[0009] Furthermore, teeth are arranged on both sides of the double-sided tooth, and the side of the double-sided tooth close to gear one is meshed with gear one, and the side of the double-sided tooth close to gear two is meshed with gear two.

[0015] Furthermore, the two belts are located at both ends of the long rod pulley, and the sound grille is located on the moving path of the rubber scraper.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The sound grille is shielded away from the outdoor speaker by a waterproof roll cloth. The box and the waterproof roll cloth form a closed cavity to isolate the sound grille from the external rainstorm environment, so as to prevent the sound grille from becoming a channel for rainwater to penetrate into the outdoor speaker under the continuous impact and invasion of rainwater in the rainstorm environment. This ensures the safety of key components such as speakers and circuits inside the outdoor speaker, and ensures the normal operation of the outdoor speaker. At the same time, it can prevent rainwater from contacting the sound grille and internal components of the outdoor speaker, causing problems such as rust on metal parts and aging of plastic parts, thus ensuring the service life of the outdoor speaker.

[0018] The filtered air can be used to cool the interior of the outdoor speakers, ensuring that even when natural convection is blocked, there is still continuous air flow inside the outdoor speakers, thereby efficiently removing heat, maintaining the normal operating temperature of the speakers, and extending the service life of electronic components. Heavy rain is usually accompanied by changes in temperature and humidity, and traditional natural heat dissipation methods may be greatly affected. At this time, active heat dissipation by inhaling air can be free from excessive interference from changes in the external environment, maintaining a relatively stable heat dissipation efficiency, and allowing outdoor speakers to operate reliably under various complex weather conditions;

[0019] Use the scraper rod to scrape away dust, leaves and other impurities on the surface of the air outlet to ensure that the outdoor speaker is always unobstructed, so that the heat dissipation process is not hindered, and the heat dissipation efficiency is improved. In addition, since the air outlet always outputs air to the outside of the outdoor speaker, rainwater cannot penetrate into the interior of the outdoor speaker through the air outlet;

[0020] Use a rubber scraper to scrape away impurities such as leaves and dust on the sound grille to prevent impurities from clogging the sound grille. This ensures that the sound passes through the grille smoothly, making the sound quality of the outdoor speakers clearer and more transparent, improving the user's listening experience. At the same time, it prevents impurities from adhering to the sound grille for a long time, causing corrosion or wear to the sound grille. Cleaning these impurities can protect the appearance and structural integrity of the sound grille, making it more durable.

[0021] By performing the three functions of shielding, heat dissipation and scraping impurities simultaneously, outdoor audio equipment can be protected quickly and effectively on rainy days. This integrated design avoids the waste of time and energy caused by operating each function separately, and improves overall work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiments provided by the present invention:

[0039] Example 1: Please refer to Figures 1 to 10 As shown, a large outdoor speaker includes an outdoor speaker 11 and a sound grille 12 , wherein the sound grille 12 is fixedly connected to the outdoor speaker 11 .

[0040] The outdoor speaker 11 is provided with a rain shielding assembly for shielding the sound grille 12 on rainy days, and the rain shielding assembly includes a fixing rod 21, the fixing rod 21 is fixedly connected to the top surface of the outdoor speaker 11, the top of the fixing rod 21 is fixedly connected with a rain sensor 22, the bottom end of the rain sensor 22 is fixedly connected with a micro motor 23, the bottom end of the micro motor 23 is fixedly connected with a gear 24, the top surface of the outdoor speaker 11 is fixedly connected with a fixing block 25, the top of the fixing block 25 is slidably connected with a double-sided tooth 26, the end of the double-sided tooth 26 away from the sound grille 12 is slidably connected with a single tooth block 27, two springs 28 are symmetrically fixedly connected between the upper and lower surfaces of the single tooth block 27 and the double-sided tooth 26, the top surface of the outdoor speaker 11 is rotatably connected with a gear 29, both sides of the double-sided tooth 26 are provided with teeth, the side of the double-sided tooth 26 close to the gear 24 is meshed with the gear 24, and the double-sided tooth 2 The side close to the gear 29 is meshed with the gear 29, and the top of the gear 29 is fixedly connected with a take-up drum 210. The side of the outdoor speaker 11 close to the sound grille 12 is fixedly connected with a casing 211. The inner wall of the bottom end of the casing 211 is rotatably connected with a fixed shaft 212. The surface of the fixed shaft 212 is wrapped with a waterproof roll 213. One end of the waterproof roll 213 is fixedly connected with the fixed shaft 212. The inner wall of the casing 211 and the top of the fixed shaft 212 are fixedly connected with a bottom plate 214. The waterproof roll 213 passes through the bottom plate 214. The end of the waterproof roll 213 away from the fixed shaft 212 is fixedly connected with a counterweight 215. The counterweight 215 is slidably connected to the inner wall of the casing 211. The top surface of the counterweight 215 is fixedly connected with a pull rope 216. The end of the pull rope 216 away from the counterweight 215 is fixedly connected to the take-up drum 210, and the pull rope 216 passes through the top of the casing 211.

[0041] Among them: the rain sensor 22 and the micro motor 23 are electrically connected through the controller. Specifically: when the rain sensor 22 detects rain in the external environment, the micro motor 23 is started through the controller. When the external environment is dry, the rain controller 22 turns off the micro motor 23 through the controller. A torsion spring is arranged between the fixed shaft 212 and the sleeve box 211, which is not shown in the figure and is used to help the fixed shaft 212 to reset after rotation.

[0042] The teeth of the double-sided latching teeth 26 close to the gear 1 24 are larger than the teeth of the gear 2 29 , so that when the gear 1 24 drives the double-sided latching teeth 26 to move, it can drive the gear 2 29 to rotate more times.

[0043] The shape and size of the single tooth block 27 are the same as the shape and size of the single tooth of the double-sided latching tooth 26 close to the gear 1 24 , so that the double-sided latching tooth 26 can mesh with the single tooth block 27 when in action.

[0044] When the rain shielding assembly is in use, in the case of heavy rain in the external environment, rain falls on the top surface of the rain sensor 22. At this time, the rain sensor 22 starts the micro motor 23 through the controller, so that the micro motor 23 rotates synchronously counterclockwise, thereby driving the gear 1 24 to rotate synchronously counterclockwise. While the gear 1 24 rotates counterclockwise, it drives the double-sided latch 26 to slide on the fixed block 25 toward the sound grille 12, and then the double-sided latch 26 drives the gear 2 2 to rotate synchronously. 9 rotates synchronously, and the gear 29 drives the take-up drum 210 to rotate synchronously while rotating. The take-up drum 210 tightens the drawstring 216 while rotating, and the drawstring 216 is wound around the side wall of the take-up drum 210, so that the drawstring 216 pulls the counterweight block 215 upward, so that the counterweight block 215 slides upward on the inner wall of the casing 211, and the counterweight block 215 drives the waterproof roll cloth 213 to move synchronously while moving upward, so that the waterproof roll cloth 213 slides upward on the bottom plate 214.

[0045] During this process, the double-sided latch teeth 26 drive the single tooth block 27 to move synchronously in the direction of the sound grille 12. When the single tooth block 27 moves to the meshing position with the gear 1 24, the gear 1 24 pushes the single tooth block 27 in the direction of the sound grille 12. In this process, the single tooth block 27 slides on the surface of the double-sided latch teeth 26 and gradually compresses the spring 28. When the single tooth block 27 is located on the side of the gear 1 24 close to the sound grille 12 and the gear 1 24 no longer conflicts with the single tooth block 27, the spring 28 elastically stretches to push the single tooth block 27 in the direction of the gear 1 24. In this process, since the gear 1 24 is in a state of continuous rotation, the rotating teeth of the gear 1 24 will intermittently conflict with the single tooth block 2 7, the single tooth block 27 is pushed toward the sound grille 12, and then the single tooth block 27 contacts with the gear 1 24 again under the elastic extension of the spring 28, and in this reciprocating manner, it can be achieved that during the rotation of the micro motor 23, the single tooth block 27 is always located on the side of the gear 1 24 close to the sound grille 12, and then the position of the double-sided latch tooth 26 is also located on the side of the gear 1 24 close to the sound grille 12. Compared with when the micro motor 23 is not rotating, the double-sided latch tooth 26 moves a distance toward the sound grille 12, and after the displacement, it can continue to contact the single tooth block 27 with the gear 1 24, so that the position of the double-sided latch tooth 26 is relatively fixed, so that the take-up drum 210 maintains the winding state of the winding rope 216.

[0046] When the position of the double-sided latch 26 is relatively fixed, the counterweight 215 contacts the top of the inner wall of the casing 211, and the waterproof roll cloth 213 completely covers the sound grille 12 away from the side of the outdoor speaker 11. The casing 211 and the waterproof roll cloth 213 form a closed cavity, which isolates the sound grille 12 from the external rainstorm environment, and prevents the sound grille 12 from becoming a channel for rainwater to penetrate into the outdoor speaker 11 under the continuous impact and invasion of rainwater in the rainstorm environment, thereby ensuring the safe use of key components such as speakers and circuits inside the outdoor speaker 11 and ensuring the normal operation of the outdoor speaker 11. At the same time, it can prevent rainwater from contacting the sound grille 12 and the internal components of the outdoor speaker 11, which will cause rust on metal parts and aging of plastic parts, thereby ensuring the service life of the outdoor speaker 11.

[0047] When the rainstorm outside dissipates, the micro motor 23 stops rotating, and the pull rope 216 is pulled downward on the casing 211 under the deadweight of the counterweight 215 and the waterproof roll 213 until the counterweight 215 contacts the bottom plate 214 and the waterproof roll 213 is wound around the fixed shaft 212 and reset. At the same time, the take-up drum 210 drives the gear 2 29 to rotate in the opposite direction, so that the double-sided latch 26 moves away from the sound grille 12 until the double-sided latch 26 is reset.

[0048] Embodiment 2: Since heavy rain is often accompanied by strong winds, strong winds may change the direction of air flow around the outdoor speaker 11, making it impossible for air to circulate normally through the air inlet 13 and the air outlet 14. In addition, debris, leaves, etc. carried by the wind may also block the air outlet 14, further hindering heat dissipation. At the same time, rainwater may also enter the interior of the outdoor speaker 11 through the air inlet 13, affecting the internal structure of the outdoor speaker 11.

[0049] See also Figures 2 to 8As shown, a large outdoor speaker also includes an air inlet 13 and an air outlet 14, the air inlet 13 and the air outlet 14 are opened on the side of the outdoor speaker 11 close to the rain sensor 22, and a heat dissipation component for dissipating heat inside the outdoor speaker 11 is provided on the outdoor speaker 11, and the heat dissipation component includes a waterproof shell 31, the waterproof shell 31 is fixedly connected to the outer wall of the outdoor speaker 11 close to the rain sensor 22, and the top of the waterproof shell 31 is rotatably connected to a linkage shaft 32, which passes through the waterproof shell 31 and extends to the waterproof shell 31. At the bottom, the top of the linkage shaft 32 is fixedly connected to the bottom of the gear 24, and a fan blade 33 is fixedly connected to the linkage shaft 32 and located inside the waterproof shell 31. A filter sponge 34 is inserted on the side of the waterproof shell 31 close to the air inlet 13, and a bottom bevel gear 35 is fixedly connected to the bottom end of the linkage shaft 32. A long-handled bevel gear 36 is rotatably connected to the outer wall of the outdoor speaker 11 close to the bottom bevel gear 35. The long-handled bevel gear 36 is meshed with the bottom bevel gear 35, and a dust scraper rod 37 is fixedly connected to the end of the long-handled bevel gear 36 close to the outdoor speaker 11.

[0050] Among them: the waterproof shell 31 is provided with two openings, the opening on one side of the waterproof shell 31 close to the outdoor speaker 11 covers the air inlet 13, the filter sponge 34 is located on the path of the outside air entering the air inlet 13, the long-handled bevel gear 36 is located at the top of the air outlet 14, and the rotating diameter of the dust scraper rod 37 covers the air outlet 14.

[0051] The fan blades 33 are rotatably arranged to inhale air from the outside through the bottom opening of the waterproof shell 31 .

[0052] Wherein: the side of the scraper rod 37 close to the air outlet 14 is configured as a brush surface.

[0053] Specifically, the user can insert and remove the replacement filter sponge 34 from the waterproof shell 31 to ensure that the filter sponge 34 is in a dry state when it is ready for use.

[0054] When the heat dissipation component is in use and the rain shield component is in operation, gear 1 24 rotates, and the linkage shaft 32 is driven to rotate synchronously while the gear 1 24 rotates. The linkage shaft 32 rotates to absorb wind through the fan blades 33, so that the outside air enters the cavity of the waterproof shell 31 from the bottom end of the waterproof shell 31, and is filtered by the filter sponge 34 to filter the water vapor in the outside air. The filtered air enters the cavity of the outdoor speaker 11 through the air inlet 13 and is discharged to the outside through the air outlet 14.

[0055] Since the air on a rainy day is lower than the internal temperature of the equipment inside the outdoor speaker 11, the filtered air can cool the inside of the outdoor speaker 11, ensuring that even when natural convection is blocked, there is still continuous air flow inside the outdoor speaker 11, thereby efficiently taking away the heat, maintaining the normal operating temperature of the speaker, and extending the service life of electronic components. Rainy weather is usually accompanied by changes in temperature and humidity, and traditional natural heat dissipation methods may be greatly affected. At this time, active heat dissipation by inhaling air can be free from excessive interference from changes in the external environment, maintaining a relatively stable heat dissipation efficiency, and allowing the outdoor speaker 11 to operate reliably under various complex weather conditions.

[0056] Furthermore, the bottom opening design of the waterproof shell 31 ensures that the air sucked in by the fan blades 33 does not directly contain a large amount of water vapor, and can prevent external rainwater from entering the air inlet 13.

[0057] When the linkage shaft 32 rotates, the linkage shaft 32 drives the long-handled bevel gear 36 to rotate synchronously through the bottom bevel gear 35, and the long-handled bevel gear 36 drives the scraper rod 37 to rotate synchronously. The brush surface of the scraper rod 37 scrapes off the dust, leaves and other impurities on the surface of the air outlet 14, ensuring that the outdoor speaker 11 always remains unobstructed, allowing the heat dissipation process to be unimpeded, thereby improving the heat dissipation efficiency. In addition, since the air outlet 14 always outputs air flow to the outside of the outdoor speaker 11, rainwater cannot penetrate into the interior of the outdoor speaker 11 through the air outlet 14.

[0058] Embodiment 3: Since the outdoor speaker 11 is used outdoors, the outdoor air itself contains various dust particles, such as soil particles, pollen, industrial dust, etc. These dusts will continue to float and move in the air under the action of wind, airflow, etc. When the outdoor speaker 11 is working in an outdoor environment, the sound grille 12 is directly exposed to the air, and it is easy to absorb these dusts. In addition, the wind can blow the leaves to the vicinity of the outdoor speaker 11 and make them contact with the sound grille 12. If the wind is strong, the leaves may be forced to be pressed on the sound grille 12 of the outdoor speaker 11, and the sound grille 12 usually has a certain pore structure. The leaves may be stuck in these pores and thus adhere to the sound grille 12.

[0059] See also Figures 2 to 10As shown, a large outdoor speaker also includes a scraping assembly arranged on the outdoor speaker 11, and the scraping assembly is used to scrape dust and leaves on the side of the sound grille 12 away from the outdoor speaker 11. The scraping assembly includes two long rod pulleys 41, and the two long rod pulleys 41 are symmetrically connected to the inner wall of the casing 211 in an upper and lower distribution and rotation. The two long rod pulleys 41 are symmetrically connected to two belts 1 42 through pulleys. The two belts 1 42 are located at both ends of the long rod pulleys 41, and a rubber scraper 43 is fixedly connected between the outer surfaces of the two belts 1 42. The end of the long rod pulley 41 at the top close to the rain sensor 22 passes through the casing 211, and the end of the long rod pulley 41 at the top that passes through the casing 211 is fixedly connected to a short handle pulley 44, and a belt 2 45 is connected between the short handle pulley 44 and the long handle bevel gear 36 through a pulley transmission. The outdoor speaker 11 and the outer side wall of the casing 211 are jointly fixedly connected with a water retaining plate 46.

[0060] Wherein: the water baffle 46 is located on the top of the belt 2 45, and the water baffle 46 is used to prevent the belt 2 45 from slipping due to rainwater on rainy days.

[0061] Wherein: the sound grille 12 is located on the moving path of the rubber scraper 43 .

[0062] Specifically, the user can clean the dust and impurities scraped off the sound grille 12 by the rubber scraper 43 from the top surface of the bottom plate 214 out of the casing 211 .

[0063] When the cleaning component is in use, the shielding component and the heat dissipation component are in operation. At this time, the waterproof roll cloth 213 shields the sound grille 12, and the long-handled bevel gear 36 rotates. When the long-handled bevel gear 36 rotates, the long-handled bevel gear 36 drives the short-handled pulley 44 to rotate synchronously through the belt 2 45. When the short-handled pulley 44 rotates, it drives a long-bar pulley 41 at the top to rotate. When the long-bar pulley 41 at the top rotates, it drives the long-bar pulley 41 at the bottom to rotate synchronously through the two belts 1 42. At this time, the two belts 1 42 are transmitted at both ends of the two long-bar pulleys 41, and then the rubber scraper 43 is driven to transmit synchronously while the two belts 1 42 are transmitting. Then, during the movement of the rubber scraper 43, The triangular surface of the rubber scraper 43 contacts the sound grille 12, pushing the dust and leaves stuck on the surface of the sound grille 12 to move together. As the rubber scraper 43 continues to move, when the rubber scraper 43 moves to the side of the belt 42 away from the sound grille 12, the rubber scraper 43 no longer contacts the sound grille 12. Under the action of gravity, the dust and leaves fall to the top surface of the bottom plate 214. As the long rod pulley 41 continues to rotate, the rubber scraper 43 will repeatedly fit and separate from the sound grille 12, scraping off the remaining leaves and dust on the sound grille 12. Since the waterproof roll cloth 213 has been unfolded upward at this time, the leaves and dust scraped off by the rubber scraper 43 will not be blown up by the wind again and attached to the sound grille 12.

[0064] The rubber scraper 43 is used to scrape off impurities such as leaves and dust on the sound grille 12 to prevent impurities from clogging the sound grille 12, thereby ensuring that sound passes through the sound grille 12 smoothly, making the sound quality of the outdoor speaker 11 clearer and more transparent, thereby improving the user's auditory experience. At the same time, impurities are prevented from adhering to the sound grille 12 for a long time, thereby causing corrosion or wear to the sound grille 12. Cleaning these impurities can protect the appearance and structural integrity of the sound grille 12, thereby making it more durable.

[0065] And the three functions of shielding, heat dissipation and scraping impurities are carried out simultaneously, which can quickly and effectively protect the outdoor audio equipment on rainy days. This integrated design avoids the waste of time and energy caused by operating each function separately, and improves the overall work efficiency.
