Description

Technical Field

[0001] The present invention relates to the technical field of audio technology, in particular to waterproof and rainproof audio equipment for squares. Background Art

[0002] There are usually speakers in wider squares. These speakers are divided into two types: fixed and mobile. Both types of speakers need to be rainproof and waterproof. Existing square speakers usually only have sealing rings to protect the speakers from rain and water. However, this method usually has the following problems:

[0003] For example, according to the Chinese patent publication number "CN202410451198.9", a patent document entitled "An intelligent waterproof speaker for squares and its rainproof method" is disclosed. The application document uses a rotating method to throw out the accumulated water attached to the surface of the speaker, thereby achieving the waterproof and rainproof effect. However, if the rain is heavy, the speaker in the patent application will be in a rotating state all the time, which will bring new technical problems. For example, continuous rotation will cause damage to the corresponding rotating device, and eventually lose the waterproof and rainproof effect.

[0004] Secondly, the speakers of some speakers are funnel-shaped. At the same time, in order to ensure the broadcasting effect, the speakers of the speakers are tilted upward. Therefore, this setting is more likely to cause water accumulation at the broadcasting speakers. It is necessary to drain the accumulated water on the broadcasting speakers in time.

[0005] For this purpose, we designed waterproof and rainproof speakers for squares. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that if it rains heavily, the speakers in the existing technology will be in a rotating state all the time, which will bring new technical problems. For example, continuous rotation will cause the corresponding rotating device to be damaged, and eventually lose the waterproof and rainproof function. The waterproof and rainproof speakers for squares are proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] Preferably, the top bracket is fixed to the top of the speaker shell body, and a plurality of telescopic tubes for draining rainwater are opened on the water storage gutter. The telescopic tubes slide on the water storage gutter through the seepage holes. A floating plate is fixed at one end of the telescopic tube extending into the water storage gutter. The telescopic tube has a water outlet hole, and a plurality of side holes connected to the water outlet hole are opened on the side wall of the telescopic tube.

[0010] Preferably, a side groove is provided on the side wall of the water seepage hole, and a sliding rheostat is arranged in the side groove. A metal rod is fixed to the outer wall of the telescopic tube, which is against the sliding rheostat and vertically raised and lowered in the side groove. A wireless sensor is provided in the main body of the audio housing, and the wireless sensor is connected to one end of the sliding rheostat and the metal rod through wires.

[0011] Preferably, a counterweight is provided at the bottom of the water storage rain gutter, and the water storage rain gutter rotates on the top bracket through a side shaft.

[0012] Preferably, an annular inner wall groove is opened on the inner wall of the speaker housing body, the hollow rubber ring is installed in the inner wall groove, and the other end of the connecting hard pipe extends into the inner wall groove and is connected with the hollow rubber ring.

[0013] Preferably, a fixing rod is also fixed in the body of the audio shell, a push tube slides on the fixing rod, an end abutment plate is fixed to one end of the fixing rod facing the sliding plate, a reset spring is provided between the push tube and the end abutment plate for resetting the sliding plate, and the push tube is connected to the sliding plate through a pillow block and a connecting rod.

[0014] Preferably, a telescopic disk connected to the push tube slides coaxially on the fixed rod, a rotating disk rotates coaxially on the fixed rod, and a triangular block fixed radially toward the side of the rotating disk is fixed on the telescopic disk, the cross-section of the triangular block is an isosceles triangle, and a rod that abuts against the triangular block is provided on the rotating disk, and a driving mechanism for driving the rotating disk to rotate is provided in the main body of the audio housing.

[0015] Preferably, a radial sliding hole is provided on the rotating disk in a radial direction, and the push rod slides on the radial sliding hole through a sliding block, and a chamfer is provided on one end of the push rod facing the telescopic disk.

[0016] Preferably, a driving motor is provided on the side wall of the rotating disk, and a screw rod extending radially into the radial sliding hole is fixed to the output end of the driving motor, a threaded hole adapted to the screw rod is provided on the sliding block, and the screw rod drives the sliding block to slide on the radial sliding hole through the threaded hole.

[0018] The beneficial effects of the present invention are:

[0019] 1. In the present invention, falling rainwater will fall into the water storage gutter, and then flow into the hollow rubber ring from the rubber hose at the bottom of the water storage gutter, completing the water filling operation of the hollow rubber ring, so that the originally flattened hollow rubber ring begins to expand with water. The expanded hollow rubber ring after filling with water exerts a greater squeezing force on the side wall of the sliding plate than the originally flattened hollow rubber ring, so that the hollow rubber ring originally fitted to the side wall of the sliding plate becomes tighter, that is, the hollow rubber ring has a better water-proof effect on the side wall of the sliding plate, thereby achieving the effect of driving the hollow rubber ring to expand in a rainy environment, and finally achieving a more closed and sealed effect.

[0020] 2. The more precipitation the present invention has, the more the number of rotations of the driving motor is controlled by the wireless sensor, and the push rod is driven closer to the fixed rod, then the vibration frequency of the sliding plate will be higher. This can solve the problem of heavy rainfall and rainwater accumulating for too long at the horn of the sliding plate, and the accumulated water can be ejected in time; conversely, when the rainfall decreases, the push rod is driven away from the fixed rod, and the vibration frequency of the sliding plate will be lower. Therefore, it can effectively ensure that the vibration frequency of the sliding plate will change with the change of rainfall, and avoid the vibration frequency of the sliding plate maintaining a high frequency when the rainfall decreases, which is easy to cause damage to the horn on the sliding plate.

[0033] Reference Figures 1-11 The waterproof and rainproof speaker for squares includes a support base 2 and a speaker shell body 1 that rotates on the support base 2. A sliding plate 3 with a speaker slides on the speaker shell body 1. The bottom of the speaker shell body 1 is rotatably connected to the support base 2 through a universal joint structure. A hydraulic cylinder assembly is installed on the support base 2. The output end of the hydraulic cylinder assembly is connected to the bottom of the speaker shell body 1 through a pillow block. Therefore, after the hydraulic cylinder assembly is turned on, the speaker shell body 1 can be driven to swing along with the sliding plate 3 with the speaker on the vertical plane. Figure 1 In this state, the speaker housing body 1 drives the sliding plate 3 with the speaker to change its angle, thereby facilitating the adjustment of the elevation angle of the speaker. The hydraulic cylinder assembly uses a hydraulic rod, which is a prior art and will not be elaborated on here.

[0034] Reference Figure 7 and Figure 8 In this state, a water-proof hollow rubber ring 15 is provided between the audio housing body 1 and the sliding plate 3. An annular inner wall groove 17 is provided on the inner wall of the audio housing body 1. The hollow rubber ring 15 is installed in the inner wall groove 17. Therefore, the hollow rubber ring 15 provides a sealed condition for the gap between the audio housing body 1 and the sliding plate 3, and is used to prevent external rainwater from entering the audio housing body 1 through the gap between the audio housing body 1 and the sliding plate 3.

[0035] Reference Figure 2In this state, a connecting hard tube 16 connected to the hollow rubber ring 15 is provided at the bottom of the speaker housing body 1. The connecting hard tube 16 is a U-shaped tube, wherein one end of the connecting hard tube 16 extends into the inner wall groove 17 and is connected to the hollow rubber ring 15. The hollow rubber ring 15 is annular, and the connecting hard tube 16 is connected to the bottom position of the hollow rubber ring 15. This arrangement can ensure that rainwater flowing into the hollow rubber ring 15 will flow into the connecting hard tube 16.

[0036] A rain gutter 4 for collecting rainwater is provided on the speaker housing body 1, and a top bracket 6 is fixed on the top of the speaker housing body 1. Therefore, during normal use, the speaker housing body 1 is usually set at an elevation angle, thereby improving the efficiency of the broadcast voice. Therefore, when the speaker housing body 1 swings at an elevation angle, the top bracket 6 will also rotate in the same way, and the rain gutter 4 rotates on the top bracket 6 through the side axis, and the counterweight block is provided at the bottom of the rain gutter 4. This will make the opening of the rain gutter 4 always vertically facing upward during the swinging of the speaker housing body 1 on the vertical plane, which can maximize the efficiency of receiving rainwater. The rainwater falling from the sky will fall into the rain gutter 4, and then flow into the hollow rubber ring 15 from the rubber hose 5 at the bottom of the rain gutter 4, completing the water filling operation of the hollow rubber ring 15, and allowing the originally deflated hollow rubber ring 15 to begin to expand with water.

[0037] Furthermore, the rainwater storage trough 4 is poured into the hollow rubber ring 15 through the rubber hose 5, thereby forming Figure 2 In this state, the hollow rubber ring 15 is connected. Therefore, when rainwater gathers in the water storage gutter 4 and then flows into the hollow rubber ring 15 from the rubber hose 5, the originally flat hollow rubber ring 15 begins to expand with water. The expansion of the hollow rubber ring 15 used in this solution has the following technical effects:

[0038] First, the hollow rubber ring 15 that expands after being filled with water exerts a greater squeezing force on the side wall of the sliding plate 3 than the originally deflated hollow rubber ring 15, making the hollow rubber ring 15 that originally fits the side wall of the sliding plate 3 become tighter, that is, the hollow rubber ring 15 has a better water-proof effect on the side wall of the sliding plate 3, thereby driving the hollow rubber ring 15 to expand in a rainy environment, and finally achieving a more sealed effect.

[0039] Secondly, since the bottom of the hollow rubber ring 15 is interconnected with the connecting hard tube 16, it can ensure that rainwater is poured into the hollow rubber ring 15 from the rubber hose 5. If the hollow rubber ring 15 only has one rainwater inlet, air will be contained inside the annular hollow rubber ring 15, resulting in the rainwater being unable to be poured into the hollow rubber ring 15 due to the air pressure inside the hollow rubber ring 15, and the hollow rubber ring 15 cannot be expanded by the rainwater. Therefore, the bottom of the hollow rubber ring 15 is interconnected with the connecting hard tube 16 to ensure that rainwater is poured into the hollow rubber ring 15 through the rubber hose 5. At the same time, the air originally in the hollow rubber ring 15 can be discharged from the connecting hard tube 16, thereby ensuring that rainwater can be poured into the hollow rubber ring 15 without hindrance.

[0040] It should be noted that the top of the connecting hard pipe 16 is flush with the top of the water storage rain gutter 4, which forms a simple communicating vessel. The openings at both ends of the hollow rubber ring 15 are for the water storage rain gutter 4 and the connecting hard pipe 16. Therefore, as the rain continues, rainwater gathers in the water storage rain gutter 4. If the rainfall is not large, the narrow hollow rubber ring 15 cannot be filled, and the rainwater will gather at the lower part of the hollow rubber ring 15. The rainwater gathered at the lower part of the hollow rubber ring 15 will also prop up the lower part of the hollow rubber ring 15 to expand. Since the speaker housing body 1 is tilted at an elevation angle, rainwater will more easily gather at the bottom of the gap between the speaker housing body 1 and the sliding plate 3, which can effectively prevent rainwater from flowing into the speaker housing body 1 from the bottom of the gap between the speaker housing body 1 and the sliding plate 3.

[0041] When the rainwater increases, the rainwater will fill the hollow rubber ring 15 and exist in the water storage gutter 4. Since the top of the connecting hard pipe 16 is flush with the top of the water storage gutter 4, the liquid level in the connecting hard pipe 16 is flush with the liquid level in the water storage gutter 4, thereby ensuring that the hollow rubber ring 15 is always full of rainwater, and the hollow rubber ring 15 is fully expanded, thereby achieving a sealing effect.

[0042] An electric push rod is provided inside the speaker housing body 1 to push the sliding plate 3 to move back and forth and shake off rainwater. Therefore, by turning on the electric push rod, the sliding plate 3 can be driven to reciprocate and extend inside the speaker housing body 1, thereby shaking off the rainwater falling on the sliding plate 3 and preventing rainwater from gathering at the speaker of the sliding plate 3.

[0043] Furthermore, a plurality of telescopic tubes 8 for draining rainwater are provided on the water storage rain gutter 4. The telescopic tubes 8 slide on the water storage rain gutter 4 through the seepage holes 7. The telescopic tubes 8 extend into the water storage rain gutter 4 and a floating plate 9 is fixed at one end. The telescopic tubes 8 have a water outlet 11, and the side walls of the telescopic tubes 8 are provided with a plurality of side holes 10 connected to the water outlet 11. It should be noted that, referring to Figure 3-Figure 6In this state, when the speaker housing body 1 rotates together with the top bracket 6 , the telescopic tube 8 is in a vertical state, thereby ensuring that the telescopic tube 8 is vertically lifted under the buoyancy of the floating plate 9 .

[0044] When the hollow rubber ring 15 is filled with rainwater and some rainwater remains in the water storage gutter 4, the rainwater will submerge the float plate 9, and then the float plate 9 will lift up with the telescopic tube 8 under the action of buoyancy. It should be noted that when the rainwater is not enriched in the water storage gutter 4, the float plate 9 will not rise. When the rainfall increases, the rainwater accumulated in the water storage gutter 4 increases. At this time, the telescopic tube 8 rises, so that the side hole 10 originally blocked by the seepage hole 7 is exposed. Therefore, the rainwater in the water storage gutter 4 flows into the water outlet 11 through the side hole 10, which can discharge the rainwater accumulated in the water storage gutter 4.

[0045] It should be noted that the aperture of the side hole 10 is small, ensuring that the rainwater in the water storage gutter 4 flows out slowly. Therefore, when there is rainwater in the water storage gutter 4, the rainwater will flow out slowly, so the rainwater in the water storage gutter 4 will be in a dynamic balance, that is, rainwater flows in and rainwater flows out.

[0046] When the amount of rainwater increases, the telescopic tube 8 is lifted higher under the action of buoyancy, so that the exposed side holes 10 can allow the rainwater to flow out through the side holes 10 and the water outlet holes 11. When the amount of rainwater falling into the water storage gutter 4 is greater than the amount of rainwater flowing out, the telescopic tube 8 will continue to rise;

[0047] When the rainfall is stable, the amount of rainwater falling into the water storage gutter 4 is equal to the amount of rainwater flowing out, and the telescopic tube 8 will be stable in the water seepage hole 7;

[0048] When the rainfall decreases or stops, the rainwater in the water storage gutter 4 will no longer accumulate but will only flow out, and the telescopic tube 8 will continue to descend until the side hole 10 on the telescopic tube 8 is completely blocked by the water seepage hole 7. At this time, the rainwater in the hollow rubber ring 15 still exists. Therefore, even when the rain stops, the hollow rubber ring 15 stretched by the rainwater still presses against the sliding plate 3, and finally the water-proof sealing effect is still achieved.

[0049] A side groove 12 is formed on the side wall of the water seepage hole 7, and a sliding rheostat 14 is provided in the side groove 12. A metal rod 13 is fixed to the outer wall of the telescopic tube 8, which abuts against the sliding rheostat 14 and is vertically raised and lowered in the side groove 12. A wireless sensor is provided in the speaker housing body 1, and the wireless sensor is connected to one end of the sliding rheostat 14 and the metal rod 13 through a wire, and the wireless sensor is connected to the bottom end of the sliding rheostat 14 through a wire. Therefore, the three states of the telescopic tube 8 mentioned above will be fed back to the sliding rheostat 14;

[0050] When the telescopic tube 8 continues to rise, the telescopic tube 8 slides upward on the upper side wall of the sliding rheostat 14 with the metal rod 13, and the resistance value in the circuit increases; when the telescopic tube 8 is stable, the resistance value in the circuit remains unchanged; when the telescopic tube 8 continues to fall, the resistance value in the circuit decreases.

[0051] The wireless sensor is used to process the size of the resistance into an electrical signal, and then transmit the corresponding electrical signal to the corresponding driving device, thereby controlling the rotation speed or number of rotations of the driving device. The wireless sensor is used to convert the rainwater level in the water storage gutter 4 into an electrical signal through the size of the resistance value, and then feed the converted electrical signal back to the signal processing equipment, thereby driving the driving device to move. This is an existing technology and will not be elaborated on here.

[0052] Reference Figure 7-11 State, wherein a fixing rod 18 is also fixed in the audio housing body 1, and a pushing tube 29 is slid on the fixing rod 18, and an end abutment plate 19 is fixed to one end of the fixing rod 18 toward the sliding plate 3, and a return spring for returning the sliding plate 3 is provided between the pushing tube 29 and the end abutment plate 19, and the pushing tube 29 is connected to the sliding plate 3 through the pillow block and the connecting rod 20, so the pushing tube 29 slides on the fixing rod 18 toward the sliding plate 3 through the connecting rod 20, so that the sliding plate 3 can be pushed to move. When the pushing tube 29 is no longer subjected to external thrust, the return spring can push the pushing tube 29 back to its position, so under the dual action of external thrust and the return spring, the sliding plate 3 can be driven to slide back and forth in the audio housing body 1.

[0053] Reference Figure 9 and Figure 10 State, a telescopic disk 21 connected to the pushing tube 29 slides coaxially on the fixed rod 18, a rotating disk 24 rotates coaxially on the fixed rod 18, and a radially fixed triangular block 22 is fixed to the side of the telescopic disk 21 facing the rotating disk 24. The cross-section of the triangular block 22 is an isosceles triangle, and a push rod 23 is provided on the rotating disk 24 to resist the triangular block 22. Therefore, as the rotating disk 24 rotates, the push rod 23 can be rotated around the fixed rod 18 with the push rod 23. Since the telescopic disk 21 is connected to the rotating disk 24, the push rod 23 has a chamfered end toward the telescopic disk 21, which can push the triangular block 22 on the telescopic disk 21, allowing the triangular block 22 to push the telescopic disk 21 to slide along the axis on the fixed rod 18, so that the sliding plate 3 moves.

[0054] A driving mechanism for driving the rotating disk 24 to rotate is provided in the acoustic housing body 1. The driving mechanism is a driving motor, which drives the rotating disk 24 to rotate stably. Since a radial sliding hole 26 is radially opened on the rotating disk 24, and the push rod 23 slides on the radial sliding hole 26 through the sliding block 28, a driving motor 25 is provided on the side wall of the rotating disk 24, and a screw rod 27 is fixed to the output end of the driving motor 25, which extends radially into the radial sliding hole 26. A threaded hole adapted to the screw rod 27 is opened on the sliding block 28, and the screw rod 27 drives the sliding block 28 to slide on the radial sliding hole 26 through the threaded hole. Therefore, the electrical signal processed in the wireless sensor is transmitted to the driving motor 25 through the signal processing device, thereby controlling the number of rotations of the driving motor 25, that is, when the amount of rainwater increases, it can drive the push rod 23 to slide toward the fixed rod 18. Since the rotating disk 24 rotates under the action of the driving motor , with the push rod 23 rotating, the closer it is to the center position of the rotating disk 24, the higher the frequency at which the push rod 23 pushes the triangular block 22 to move the telescopic disk 21, so a cycle can be formed, that is, the more precipitation there is, the number of rotations of the driving motor 25 is controlled by the wireless sensor, and the push rod 23 is driven close to the fixed rod 18, so the vibration frequency of the sliding plate 3 is driven higher, which can solve the problem of heavy rainfall and rainwater accumulating for too long at the speaker of the sliding plate 3, and the accumulated water can be ejected in time; on the contrary, when the rainfall decreases, the push rod 23 is driven away from the fixed rod 18, so the vibration frequency of the sliding plate 3 is driven lower, so that it can effectively ensure that the vibration frequency of the sliding plate 3 changes with the change of rainfall, and avoid that the vibration frequency of the sliding plate 3 remains high when the rainfall decreases, which is easy to cause damage to the speaker on the sliding plate 3.

[0055] The vibration frequency of the sliding plate 3 can also be implemented as follows:

[0056] Since a drive motor is provided in the speaker housing body 1, and the wireless sensor is used to convert the rainwater level in the water storage gutter 4 into an electrical signal through the resistance value, and then feed the converted electrical signal back to the drive motor to regulate the speed of the drive motor, the push rod 23 is fixedly set on the rotating disk 24 at this time, so the vibration frequency of the sliding plate 3 is directly controlled by regulating the speed of the rotating disk 24.

[0057] The working principle of the present invention is as follows:

[0058] First, the output end of the hydraulic cylinder assembly passes through the pillow block and the bottom of the audio housing body 1. Therefore, after the hydraulic cylinder assembly is turned on, it can drive the audio housing body 1 and the sliding plate 3 with the speaker to swing at an angle in the vertical plane. The inner wall of the audio housing body 1 is provided with an annular inner wall groove 17, and the hollow rubber ring 15 is installed in the inner wall groove 17. Therefore, the hollow rubber ring 15 provides a sealed condition for the gap between the audio housing body 1 and the sliding plate 3, which is used to prevent external rainwater from entering the audio housing body 1 through the gap between the audio housing body 1 and the sliding plate 3.

[0059] When rainwater gathers in the water storage gutter 4 and then flows into the hollow rubber ring 15 from the rubber hose 5, the originally flattened hollow rubber ring 15 begins to expand with water. The expanded hollow rubber ring 15 after being filled with water exerts a greater squeezing force on the side wall of the sliding plate 3 than the originally flattened hollow rubber ring 15, making the hollow rubber ring 15 originally fitted to the side wall of the sliding plate 3 become tighter, that is, the hollow rubber ring 15 has a better water-proof effect on the side wall of the sliding plate 3, thereby driving the hollow rubber ring 15 to expand in a rainy environment, and finally achieving a more closed and sealed effect.

[0060] When the rainfall increases, the telescopic tube 8 rises higher under the action of buoyancy, and the telescopic tube 8 will continue to rise; when the rainfall is stable, the telescopic tube 8 will be stable in the water seepage hole 7; when the rainfall decreases or stops, the side holes 10 on the telescopic tube 8 are completely blocked by the water seepage hole 7, while the rainwater in the hollow rubber ring 15 still exists. Therefore, even if the rain stops, the hollow rubber ring 15 stretched by the rainwater is still against the sliding plate 3, and ultimately the water-proof sealing effect is still achieved.

[0061] The wireless sensor is used to process the size of the resistance into an electrical signal for feedback, and then transmit the corresponding electrical signal to the corresponding driving device. Therefore, the electrical signal processed in the wireless sensor is transmitted to the driving motor 25 through the signal processing device, and then the number of rotations of the driving motor 25 is controlled. That is, when the amount of rain increases, it can drive the push rod 23 to slide toward the fixed rod 18. Since the rotating disk 24 rotates under the action of the driving motor, it drives the push rod 23 to rotate. The closer to the center position of the rotating disk 24, the higher the frequency of the push rod 23 pushing the triangular block 22 to move the telescopic disk 21, so a cycle can be formed, that is, the more precipitation, the higher the frequency. , by controlling the number of revolutions of the driving motor 25 through the wireless sensor, the push rod 23 is driven close to the fixed rod 18, and the vibration frequency of the sliding plate 3 is driven higher, which can solve the problem of heavy rainfall and rainwater accumulation at the speaker of the sliding plate 3 for too long, and the accumulated water can be ejected in time; on the contrary, when the rainfall decreases, the push rod 23 is driven away from the fixed rod 18, and the vibration frequency of the sliding plate 3 is driven lower, thereby effectively ensuring that the vibration frequency of the sliding plate 3 changes with the change of rainfall, avoiding that the vibration frequency of the sliding plate 3 remains high when the rainfall decreases, which is easy to cause damage to the speaker on the sliding plate 3.
