Description

Technical Field

[0001] The present invention relates to the technical field of audio, and in particular to a multi-room wireless audio system. Background Art

[0002] With the progress of society, people yearn for a more colorful life. As a form of entertainment that has been passed down for thousands of years, singing and dancing have penetrated into the lives of people of all ethnic groups. However, with the development and progress of science and technology, people have more and more requirements for the performance forms and venues of singing and dancing. The sound system is constantly improving and perfecting with people's needs. It can meet the needs of live sound reinforcement for concerts with tens of thousands of people, or meet the needs of playing musical instruments and singing karaoke at home.

[0003] Nowadays, when people are running or climbing mountains, sometimes in order to relax, they will carry a small wireless speaker connected to the mobile phone, play music in the phone, to relax themselves. However, generally speaking, for morning runs and mountain climbing, the humidity of the air is relatively high. If the humidity entering the speaker is too high, the sound quality of the speaker will be damaged. In severe cases, the internal components of the speaker may be damaged.

[0004] Therefore, a multi-room wireless speaker is proposed. Summary of the invention

[0005] The object of the present invention is to provide a multi-room wireless speaker, which can be used in some humid environments through a dehumidification mechanism. By taking advantage of the height difference when people move, water entering the inner part of the shell can be removed, thereby avoiding the influence of water on the sound quality and components of the speaker body, improving the practicability of the device, and solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a multi-room wireless speaker, comprising a shell, a speaker body is fixedly connected to the left inner surface of the shell, a mesh cover is fixedly connected to the right side of the shell, and a dehumidification mechanism is provided on the right inner surface of the shell.

[0007] During use, the music that needs to be enjoyed is emitted by the speaker body. When it is used in some humid environments, the dehumidification mechanism can remove the water that has entered the shell through the height difference when people move up and down, thus avoiding the influence of water on the sound quality and components of the speaker body.

[0008] Preferably, the dehumidification mechanism includes a limit rod, a first spring, a gravity block, a first threaded rod, a one-way bearing, a first gear, a second gear, a reciprocating screw, a screw nut, a sponge, a pressure roller and a one-way bearing, wherein the limit rod is fixedly connected to the inner wall of the shell near the front and rear ends of the right side, the gravity block is slidably connected to the rod wall of the limit rod, the first spring is fixedly connected to the upper and lower ends of the gravity block, the first threaded rod is rotatably connected to the inner wall of the shell and is located on the right side of the limit rod, and the one-way bearing is fixedly connected to the inside of the gravity block near the right side. The interior of the one-way bearing is spirally transmitted with the rod wall of the first threaded rod, the first gear is fixedly connected to the rod wall of the first threaded rod near the upper and lower ends, the reciprocating screw is rotatably connected to the right inner wall of the shell and is located on the right side of the first threaded rod, the second gear is fixedly connected to the rod wall of the reciprocating screw near the upper and lower ends, the outer side of the first gear is meshed with the outer side of the second gear, the screw nut is slidably connected to the rod wall of the reciprocating screw, the pressure roller is movably connected between the right sides of the screw nut, and the sponge is fixedly connected to the right side of the mesh cover.

[0009] When people are climbing or running, the audio system will move up and down with the center movement of the person. At this time, the gravity block moves up and down on the rod wall of the limit rod under the support and tension of the first spring. At this time, the gravity block drives the one-way bearing fixed inside to move up and down when moving up and down. The one-way bearing makes the first threaded rod of the spiral transmission rotate when moving up and down. Because it is a one-way bearing, the one-way bearing is in an active state when the gravity block moves up. At this time, the first threaded rod does not rotate. When the gravity block moves down, the one-way bearing is in a locked state, and the one-way bearing makes the first threaded rod rotate, which makes the first threaded rod rotate in one direction. The rotation of the first threaded rod drives the first gear to rotate, and the first gear drives the meshing second gear to rotate. The rotation of the second gear drives the reciprocating screw to rotate. The rotation of the reciprocating screw causes the screw nut on the rod wall to move up and down, and the screw nut drives the pressure roller to move up and down when moving up and down. When the pressure roller moves up and down, the water adsorbed on the sponge is squeezed and removed.

[0010] Preferably, a groove is opened on the right side of the screw nut, a second spring is fixedly connected inside the groove, a support rod is fixedly connected to the right side of the second spring, a rod wall of the support rod is fixedly connected to a limiting block, and the right side of the support rod is fixedly connected to the left side of the pressure roller.

[0011] Because the pressure roller will cause certain damage to the sponge when squeezing the sponge repeatedly, the squeezing effect of the pressure roller on the sponge will decrease over time. At this time, the second spring inside the groove pushes the support rod to move to the right, and the support rod drives the pressure roller to move to the left, so as to ensure that the pressure roller always fits the sponge.

[0012] Preferably, the ratio of the diameter of the first gear to the diameter of the second gear is three to one.

[0013] The reciprocating screw rod is equivalent to the first threaded rod rotating faster.

[0014] Preferably, a vertical rod is fixedly connected to the inner wall of the lower end of the shell, a cross rod is fixedly connected to the right side of the vertical rod near the upper end, a first return spring is fixedly connected to the outer side of the cross rod, a fan blade is fixedly connected to the outer side of the first return spring, and a tension rope is fixedly connected to the right side of the fan blade near the upper and lower ends, and the end of the tension rope away from the fan blade is fixedly connected to the gravity block.

[0015] When the gravity block moves up and down, the tension rope will be pulled, and when the tension rope is pulled, the fan blades will rotate. When the gravity block moves up and down, the fan blades will reset under the action of the first return spring, so that the fan blades will continue to rotate and blow air to the outside of the casing.

[0016] Preferably, support plates are fixedly connected at the four corners of the right inner surface of the shell, a knocking rod is rotatably connected at the center of the support plate, a second return spring is fixedly connected at the center of the support plate, the interior of the second return spring is sleeved with the wall of the knocking rod, and cams are fixedly connected at both upper and lower ends of the reciprocating screw rod.

[0017] When the reciprocating screw rotates, the cam is driven to rotate, and the cam squeezes the knocking rod when rotating. When the cam and the knocking rod are misaligned, the knocking rod is reset under the action of the second return spring. At the same time, the knocking rod knocks on the mesh cover to make the mesh cover vibrate.

[0018] Preferably, a small hole is provided at the lower end of the shell near the right side.

[0019] The squeezed water can be discharged.

[0020] Preferably, the outer surface of the shell is coated with a hydrophobic coating.

[0021] You will sweat when exercising, and the hydrophobic coating prevents water from staying on the surface of the shell, thus playing an anti-slip role.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The dehumidification mechanism can be used in some humid environments. The water entering the shell can be removed by the height difference when people move up and down, thus avoiding the influence of water on the sound quality and components of the main body of the speaker, and improving the practicality of the device;

[0024] 2. By rotating the fan blades continuously, the air flow rate on the surface of the sponge can be accelerated, the evaporation of water can be accelerated, the sponge can be kept as dry as possible, the water absorption effect can be improved, and the practicality of the device can be improved. By knocking on the mesh cover with a knocking stick, the mesh cover can be vibrated, and the dust attached to the surface can be shaken off, thereby improving the cleanliness of the mesh cover.

DETAILED DESCRIPTION

[0031] 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.

[0032] See also Figures 1 to 5 , the present invention provides a technical solution:

[0033] A multi-room wireless speaker, such as Figures 1 to 3 As shown, it comprises a housing 1, a sound body 2 is fixedly connected to the left inner surface of the housing 1, a mesh cover 8 is fixedly connected to the right side of the housing 1, and a dehumidification mechanism 23 is provided on the right inner surface of the housing 1;

[0034] During operation, during use, the music to be enjoyed is emitted through the audio body 2. The dehumidification mechanism 23 can remove water entering the shell 1 through the height difference when a person moves when the audio body 2 is used in some humid environments, thereby avoiding the influence of water on the sound quality and components of the audio body 2.

[0035] As an embodiment of the present invention, Figures 1 to 3 As shown, the dehumidification mechanism 23 includes a limit rod 3, a first spring 5, a gravity block 4, a first threaded rod 29, a one-way bearing 6, a first gear 25, a second gear 10, a reciprocating screw 7, a screw nut 15, a sponge 9, a pressure roller 19 and a one-way bearing 6, wherein the limit rod 3 is fixedly connected to the inner wall of the shell 1 near the front and rear ends of the right side, the gravity block 4 is slidably connected to the rod wall of the limit rod 3, the first spring 5 is fixedly connected to the upper and lower ends of the gravity block 4, the first threaded rod 29 is rotatably connected to the inner wall of the shell 1 and is located on the right side of the limit rod 3, the one-way bearing 6 is fixedly connected to the inner part of the gravity block 4 near the right side, and the interior of the one-way bearing 6 is spirally connected to the rod wall of the first threaded rod 29. The first gear 25 is fixedly connected to the rod wall of the first threaded rod 29 near the upper and lower ends, the reciprocating screw rod 7 is rotatably connected to the right inner wall of the housing 1 and is located on the right side of the first threaded rod 29, the second gear 10 is fixedly connected to the rod wall of the reciprocating screw rod 7 near the upper and lower ends, the outer side of the first gear 25 is meshed with the outer side of the second gear 10, the screw nut 15 is slidably connected to the rod wall of the reciprocating screw rod 7, the pressure roller 19 is movably connected between the right sides of the screw nut 15, the sponge 9 is fixedly connected to the right side of the mesh cover 8, the diameter ratio of the first gear 25 to the diameter of the second gear 10 is three to one, and a small hole 21 is opened at the lower end of the housing 1 near the right side;

[0036] During operation, because people are climbing or running, the sound system will move up and down with the center of the person's movement. At this time, the gravity block 4 moves up and down on the rod wall of the limit rod 3 under the support and tension of the first spring 5. At this time, the gravity block 4 drives the one-way bearing 6 fixedly connected inside to move up and down when moving up and down. The one-way bearing 6 causes the first threaded rod 29 of the spiral transmission to rotate when moving up and down. Because it is a one-way bearing 6, it is explained here that the inner wall of the one-way bearing 6 is provided with a thread matching the first threaded rod 29. Therefore, when the gravity block 4 moves up, the one-way bearing 6 is in an active state, and the first threaded rod 29 does not rotate. When the gravity block 4 moves down, the one-way bearing 6 is in a locked state. The one-way bearing 6 causes the first threaded rod 29 to rotate, thereby causing the first threaded rod 29 to rotate in one direction. The rotation of the first threaded rod 29 drives the first gear 25 to rotate, and the first gear 25 drives the meshing second gear 10 to rotate. The rotation of the second gear 10 drives the reciprocating screw 7 to rotate. The rotation of the reciprocating screw 7 causes the screw nut 15 on the rod wall to move up and down. The screw nut 15 drives the pressure roller 19 to move up and down when moving up and down. When the pressure roller 19 moves up and down, the water adsorbed on the sponge 9 is squeezed and removed, and the squeezed water flows out through the small hole 21. In this way, the dryness inside the housing 1 can be maintained to avoid the influence of water vapor on the internal components. The reciprocating screw 7 can rotate faster through the diameter ratio of the first gear 25 and the second gear 10.

[0037] As an embodiment of the present invention, Figure 3 As shown, a groove 17 is provided on the right side of the screw nut 15, a second spring 16 is fixedly connected inside the groove 17, a support rod 18 is fixedly connected to the right side of the second spring 16, a rod wall of the support rod 18 is fixedly connected to a limiting block 20, and the right side of the support rod 18 is fixedly connected to the left side of the pressure roller 19;

[0038] During operation, because the pressure roller 19 repeatedly squeezes the sponge 9, there will be a certain amount of wear on the sponge 9. Over time, the squeezing effect of the pressure roller 19 on the sponge 9 will decrease. At this time, the second spring 16 inside the groove 17 pushes the support rod 18 to move to the right, and the support rod 18 drives the pressure roller 19 to move to the left. This ensures that the pressure roller 19 is always in contact with the sponge 9, ensuring the squeezing effect and increasing the practicality of the device.

[0039] As an embodiment of the present invention, Figure 4As shown, a vertical rod 26 is fixedly connected to the inner wall of the lower end of the housing 1, a cross rod 28 is fixedly connected to the right side of the vertical rod 26 near the upper end, a first return spring 27 is fixedly connected to the outer side of the cross rod 28, a fan blade 24 is fixedly connected to the outer side of the first return spring 27, a tension rope 22 is fixedly connected to the right side of the fan blade 24 near the upper and lower ends, and one end of the tension rope 22 away from the fan blade 24 is fixedly connected to the gravity block 4;

[0040] During operation, when the gravity block 4 moves up and down, the tension rope 22 is pulled, and when the tension rope 22 is pulled, the fan blades 24 are driven to rotate. When the gravity block 4 moves up and down, the fan blades 24 are reset under the action of the first return spring 27. In this way, the fan blades 24 are kept rotating, which can speed up the air flow rate on the surface of the sponge 9, speed up the evaporation of water, keep the sponge 9 as dry as possible, improve the water absorption effect, and improve the practicality of the device.

[0041] As an embodiment of the present invention, Figure 3 and Figure 5 As shown, the four corners of the right inner surface of the housing 1 are fixedly connected with a support plate 11, the center of the support plate 11 is rotatably connected with a knocking rod 12, the center of the support plate 11 is fixedly connected with a second return spring 13, the interior of the second return spring 13 is sleeved with the rod wall of the knocking rod 12, and the upper and lower ends of the reciprocating screw rod 7 are fixedly connected with cams 14;

[0042] During operation, when the reciprocating screw 7 rotates, it drives the cam 14 to rotate. The cam 14 squeezes the knocking rod 12 when rotating. When the cam 14 and the knocking rod 12 are misaligned, the knocking rod 12 is reset under the action of the second return spring 13. At the same time, the knocking rod 12 knocks on the mesh cover 8, causing the mesh cover 8 to vibrate, shaking off the dust attached to the surface, thereby improving the cleanliness of the mesh cover 8.

[0043] Working principle:

[0044] During operation, during use, the music that needs to be appreciated is emitted through the sound body 2. Through the dehumidification mechanism 23, when it is used in some humid environments, the water entering the shell 1 is removed through the height difference when people move up and down, thereby avoiding the influence of water on the sound quality and components of the sound body 2. Because when people are climbing or running, the sound will move up and down following the center movement of the person. At this time, the gravity block 4 moves up and down on the rod wall of the limit rod 3 under the support and tension of the first spring 5. At this time, the gravity block 4 drives the internal fixed one-way bearing 6 to move up and down when moving up and down. When the one-way bearing 6 moves up and down, the first threaded rod 29 of the spiral transmission rotates. Because it is a one-way bearing 6, so when the gravity block 4 moves up, the one-way bearing 6 is in an active state, and the first threaded rod 29 does not rotate at this time. When the gravity block 4 moves down, the one-way bearing 6 is in a locked state, and the one-way bearing 6 causes the first threaded rod 29 to rotate, so that the first threaded rod 29 rotates in one direction. The rotation of the first threaded rod 29 drives the first gear 25 to rotate, and the first gear 25 drives the meshing second gear 10 to rotate. The rotation of the second gear 10 drives the reciprocating screw 7 to rotate. The rotation of the reciprocating screw 7 causes the screw nut 15 on the rod wall to move up and down. When the screw nut 15 moves up and down, it drives the pressure roller 19 to move up and down. When the pressure roller 19 moves up and down, the water adsorbed on the sponge 9 is squeezed and removed. , the squeezed water flows out through the small hole 21, which can maintain the dryness inside the shell 1 and avoid the influence of water vapor on the internal components. The diameter ratio of the first gear 25 and the second gear 10 makes the reciprocating screw 7 rotate faster. Because the pressure roller 19 will cause a certain loss to the sponge 9 when repeatedly squeezing the sponge 9, the squeezing effect of the pressure roller 19 on the sponge 9 will decrease over time. At this time, the second spring 16 inside the groove 17 pushes the support rod 18 to move to the right, and the support rod 18 drives the pressure roller 19 to move to the left. This ensures that the pressure roller 19 is always in contact with the sponge 9, ensuring the squeezing effect and increasing the practicality of the device. When the gravity block 4 moves up and down, it will pull the tension rope 22, and the tension rope 22 will be pulled when it is pulled. When the reciprocating screw 7 rotates, it drives the fan blade 24 to rotate. When the gravity block 4 moves up and down, the fan blade 24 is reset under the action of the first return spring 27. In this way, the fan blade 24 keeps rotating, which can accelerate the air flow rate on the surface of the sponge 9, accelerate the evaporation of water, keep the sponge 9 as dry as possible, improve the water absorption effect, and improve the practicality of the device. When the reciprocating screw 7 rotates, it drives the cam 14 to rotate. The cam 14 squeezes the knocking rod 12 when rotating. When the cam 14 and the knocking rod 12 are misaligned, the knocking rod 12 is reset under the action of the second return spring 13. At the same time, the knocking rod 12 knocks on the mesh cover 8, causing the mesh cover 8 to vibrate, shake off the dust attached to the surface, and improve the cleanliness of the mesh cover 8.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
