Waterproof and rainproof speakers for the square

Abstract

This invention relates to the field of audio technology and discloses a waterproof and rainproof speaker for use in public squares. The speaker includes a support base and a speaker housing that rotates on the support base. A sliding plate with a speaker slids on the speaker housing, and a water-repellent hollow rubber ring is provided between the speaker housing and the sliding plate. In this invention, rainwater falls into a water-collecting trough and then flows through a rubber hose at the bottom of the trough into the hollow rubber ring, filling it with water. This causes the originally flat hollow rubber ring to expand. The expanded hollow rubber ring exerts greater pressure on the sidewall of the sliding plate than the originally flat one, making the hollow rubber ring, which was originally attached to the sidewall of the sliding plate, more tightly. This improves the water-repellent effect of the hollow rubber ring on the sidewall of the sliding plate, thus achieving a more secure seal in rainy conditions.

Description

Technical Field

[0001] This invention relates to the field of audio technology, and more particularly to waterproof and rainproof audio equipment for use in public squares. Background Technology

[0002] In relatively spacious squares, there are usually sound systems, which come in two types: fixed and mobile. Both types require rain and water protection. However, existing square sound systems typically only use sealing rings for rain and water protection, but this method usually has the following problems:

[0003] For example, according to Chinese Patent Publication No. CN202410451198.9, a patent document entitled "A Smart Manufacturing Waterproof Speaker for Plazas and Its Rainproof Method" is published. This application document uses a rotation method to shake off the water adhering to the surface of the speaker, thereby achieving the function of waterproofing and rainproofing. However, if the rain is heavy, the speaker in this patent application will be in a rotating state indefinitely, which will bring new technical problems. For example, continuous rotation will cause damage to the corresponding rotating device, and eventually lose the function of waterproofing and rainproofing.

[0004] Secondly, some speakers have funnel-shaped horns, and in order to ensure the broadcast effect, the horns are tilted upwards. Therefore, this setting makes it easier for water to accumulate at the horn, and it is necessary to drain the water that accumulates on the horn in a timely manner.

[0005] Therefore, we designed a waterproof and rainproof sound system for the plaza. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that if there is heavy rain, the existing sound system will be constantly rotating, which will bring new technical problems, such as damage to the corresponding rotating device due to continuous rotation, and ultimately lose its waterproof and rainproof function. The invention proposes a waterproof and rainproof sound system for squares.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The waterproof and rainproof speaker for the square includes a support base and a speaker housing that rotates on the support base. A sliding plate with a speaker slides on the speaker housing. A water-repellent hollow rubber ring is provided between the speaker housing and the sliding plate. A connecting rigid pipe communicating with the hollow rubber ring is provided at the bottom of the speaker housing. A rainwater collection tank is provided on the speaker housing to collect rainwater, and rainwater is poured into the hollow rubber ring through a rubber hose. An electric actuator is provided inside the speaker housing to push the sliding plate to reciprocate and shake off rainwater.

[0009] Preferably, the top bracket is fixed to the top of the speaker housing, and the water storage trough is provided with multiple telescopic pipes for draining rainwater. The telescopic pipes slide on the water storage trough through the seepage holes. A float plate is fixed to one end of the telescopic pipe that extends into the water storage trough. The telescopic pipe has a water outlet hole, and multiple side holes communicating with the water outlet hole are provided on the side wall of the telescopic pipe.

[0010] Preferably, a side groove is provided on the side wall of the seepage hole, and a sliding rheostat is provided in the side groove. A metal rod is fixed on the outer wall of the telescopic tube, which abuts against the sliding rheostat and moves vertically up and down in the side groove. A wireless sensor is provided in the speaker housing, and the wireless sensor is connected to one end of the sliding rheostat and the metal rod respectively through wires.

[0011] Preferably, a counterweight is provided at the bottom of the water storage trough, and the water storage trough rotates on the top support via a side shaft.

[0012] Preferably, the inner wall of the speaker housing has an annular inner wall groove, a hollow rubber ring is installed in the inner wall groove, and the other end of the connecting rigid tube extends into the inner wall groove and communicates with the hollow rubber ring.

[0013] Preferably, a fixing rod is also fixed inside the speaker housing, a push tube slides on the fixing rod, an end plate is fixed to the end of the fixing rod facing the sliding plate, a reset spring for resetting the sliding plate is provided between the push tube and the end plate, and the push tube is connected to the sliding plate through a shaft and a connecting rod.

[0014] Preferably, a telescopic disc connected to a push tube slides coaxially on the fixed rod, a rotating disc rotates coaxially on the fixed rod, and a radially fixed triangular block is fixed on the side of the telescopic disc facing the rotating disc. The triangular block has an isosceles triangle cross section. A stop bar that abuts against the triangular block is provided on the rotating disc. A drive mechanism for driving the rotating disc to rotate is provided inside the speaker housing.

[0015] Preferably, the rotating disk has radial sliding holes along the radial direction, and the push rod slides on the radial sliding holes through the sliding block, with a chamfer on the end of the push rod facing the telescopic disk.

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

[0017] Preferably, the top of the connecting rigid pipe is flush with the top of the water storage trough.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. In this invention, rainwater falls into a water storage trough and then flows from the rubber hose at the bottom of the trough into the hollow rubber ring, completing the water filling operation of the hollow rubber ring. This causes the originally flat hollow rubber ring to expand with water. The expanded hollow rubber ring exerts greater pressure on the side wall of the sliding plate than the originally flat hollow rubber ring, making the hollow rubber ring, which was originally attached to the side wall of the sliding plate, more tightly. In other words, the hollow rubber ring has a better water-repellent effect on the side wall of the sliding plate. Thus, in rainy weather, the hollow rubber ring expands, ultimately achieving a more tightly sealed effect.

[0020] 2. The more rainfall there is, the more rotations of the drive motor are controlled by a wireless sensor, causing the abutment to move closer to the fixed rod. This results in a higher vibration frequency of the sliding plate, which solves the problem of water accumulating at the horn of the sliding plate for too long during heavy rainfall, allowing the water to be ejected promptly. Conversely, when rainfall decreases, the abutment moves away from the fixed rod, resulting in a lower vibration frequency of the sliding plate. Therefore, this invention effectively ensures that the vibration frequency of the sliding plate changes with the amount of rainfall, preventing the vibration frequency from remaining high when rainfall decreases, which could easily damage the horn on the sliding plate.

Detailed Implementation

[0033] Reference Figures 1-11 The plaza-use waterproof and rainproof speaker includes a support base 2 and a speaker housing 1 that rotates on the support base 2. A sliding plate 3 with a speaker slids on the speaker housing 1. The bottom of the speaker housing 1 is rotatably connected to the support base 2 via a universal joint structure. A hydraulic cylinder assembly is mounted on the support base 2. The output end of the hydraulic cylinder assembly is connected to the bottom of the speaker housing 1 via a shaft. Therefore, when the hydraulic cylinder assembly is activated, it can cause the speaker housing 1, along with the sliding plate 3 with the speaker, to swing at an angle in the vertical plane. For example... Figure 1 In this state, the speaker housing 1 drives the sliding plate 3 with the speaker to change angle, thereby facilitating the adjustment of the speaker's elevation angle. The hydraulic cylinder assembly uses a hydraulic rod, which is existing technology and will not be elaborated on here.

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

[0035] Reference Figure 2In this configuration, the bottom of the speaker housing 1 is provided with a connecting rigid tube 16 that communicates with the hollow rubber ring 15. The connecting rigid tube 16 is a U-shaped tube, with one end of the connecting rigid tube 16 extending into the inner wall groove 17 and communicating with the hollow rubber ring 15. The hollow rubber ring 15 is annular, and the connecting rigid tube 16 communicates with the bottom of the hollow rubber ring 15. This configuration ensures that rainwater flowing into the hollow rubber ring 15 will flow into the connecting rigid tube 16.

[0036] The speaker housing 1 is equipped with a rainwater collection trough 4 for collecting rainwater. The top bracket 6 is fixed to the top of the speaker housing 1. Therefore, during normal use, the speaker housing 1 is usually set at an upward angle to improve the efficiency of voice broadcasting. So when the speaker housing 1 swings at an upward angle, the top bracket 6 will also rotate in the same way. The rainwater collection trough 4 rotates on the top bracket 6 via a side shaft. With the counterweight at the bottom of the rainwater collection trough 4, the opening of the rainwater collection trough 4 will always face vertically upward when the speaker housing 1 swings in a vertical plane, which can maximize the efficiency of receiving rainwater. Rainwater falling from the sky will fall into the rainwater collection trough 4, and then flow from the rubber hose 5 at the bottom of the rainwater collection trough 4 into the hollow rubber ring 15, completing the water filling operation of the hollow rubber ring 15 and causing the originally flat hollow rubber ring 15 to begin to expand with water.

[0037] Furthermore, rainwater is pumped into the hollow rubber ring 15 through the rubber hose 5 into the rainwater storage trough 4, thus forming... Figure 2 The hollow rubber ring 15 is connected under certain conditions, so when rainwater accumulates in the water storage trough 4, it flows from the rubber hose 5 into the hollow rubber ring 15, causing the originally flat hollow rubber ring 15 to begin to fill with water and expand. The expansion of the hollow rubber ring 15 used in this solution has the following technical effects:

[0038] Firstly, the expanded hollow rubber ring 15 after being filled with water exerts a greater compressive force on the side wall of the sliding plate 3 compared to the originally flat hollow rubber ring 15, making the hollow rubber ring 15, which was originally attached to the side wall of the sliding plate 3, become tighter. In other words, the hollow rubber ring 15 has a better water-repellent effect on the side wall of the sliding plate 3, thereby enabling the hollow rubber ring 15 to expand in rainy weather, ultimately achieving a more tightly sealed effect.

[0039] Secondly, since the bottom of the hollow rubber ring 15 is connected to the connecting rigid pipe 16, it ensures that during the process of rainwater being 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 present inside the annular hollow rubber ring 15. As a result, due to the air pressure inside the hollow rubber ring 15, rainwater cannot be poured into the hollow rubber ring 15, and the hollow rubber ring 15 cannot be expanded by the rainwater. Therefore, by connecting the bottom of the hollow rubber ring 15 to the connecting rigid pipe 16, it is ensured that during the process of rainwater being poured into the hollow rubber ring 15 from the rubber hose 5, the air originally present in the hollow rubber ring 15 can also be discharged from the connecting rigid pipe 16, thereby ensuring that rainwater can be poured into the hollow rubber ring 15 without obstruction.

[0040] It should be noted that the top of the connecting rigid pipe 16 is flush with the top of the water storage trough 4, which forms a simple communicating vessel. The two ends of the hollow rubber ring 15 are the water storage trough 4 and the connecting rigid pipe 16. Therefore, as the rain continues, rainwater accumulates in the water storage trough 4. If the rainfall is not heavy enough to fill the narrow hollow rubber ring 15, the rainwater will accumulate in the lower part of the hollow rubber ring 15. The rainwater that accumulates in the lower part of the hollow rubber ring 15 will also cause the lower part of the hollow rubber ring 15 to expand. Since the speaker housing body 1 is tilted at an upward angle, rainwater will more easily accumulate at the bottom of the gap between the speaker housing body 1 and the sliding plate 3. This 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 rainfall increases, the rainwater will fill the hollow rubber ring 15 and exist in the water storage tank 4. Since the top of the connecting rigid pipe 16 is flush with the top of the water storage tank 4, the liquid level in the connecting rigid pipe 16 is flush with the liquid level in the water storage tank 4. Therefore, the hollow rubber ring 15 is always full of rainwater, which fully expands the hollow rubber ring 15 and achieves a sealing effect.

[0042] The speaker housing 1 is equipped with an electric actuator that pushes the sliding plate 3 to reciprocate and shake off rainwater. Therefore, when the electric actuator is activated, the sliding plate 3 can be moved back and forth within the speaker housing 1, thereby shaking off the rainwater falling on the sliding plate 3 and preventing rainwater from accumulating at the speaker of the sliding plate 3.

[0043] Furthermore, the rainwater storage trough 4 is provided with multiple telescopic pipes 8 for draining rainwater. The telescopic pipes 8 slide on the rainwater storage trough 4 through the seepage holes 7. A float plate 9 is fixed to one end of the telescopic pipe 8 that extends into the rainwater storage trough 4. The telescopic pipe 8 has a water outlet hole 11, and multiple side holes 10 communicating with the water outlet hole 11 are provided on the side wall of the telescopic pipe 8. It should be noted that, referring to Figures 3-6In this state, when the speaker housing 1 rotates together with the top bracket 6, the telescopic tube 8 is in a vertical state, thus ensuring that the telescopic tube 8 is vertically raised under the buoyancy of the float plate 9.

[0044] When the hollow rubber ring 15 is filled with rainwater, and some rainwater remains in the rainwater storage tank 4, the rainwater will submerge the float 9. Consequently, the float 9 will lift up along with the telescopic pipe 8 under the action of buoyancy. It should be noted that the float 9 will not lift up when the rainwater does not accumulate in the rainwater storage tank 4. When the rainfall increases, the amount of rainwater accumulated in the rainwater storage tank 4 increases. At this time, the telescopic pipe 8 lifts up, and the side hole 10, which was originally blocked by the seepage hole 7, is exposed. Therefore, the rainwater in the rainwater storage tank 4 flows into the outlet hole 11 through the side hole 10, which can drain the rainwater accumulated in the rainwater storage tank 4.

[0045] It should be noted that the side hole 10 has a small diameter, which ensures that the rainwater in the water storage trough 4 flows out slowly. Therefore, when there is rainwater in the water storage trough 4, the rainwater will flow out slowly, so the rainwater in the water storage trough 4 will be in a dynamic balance, that is, rainwater inflow and rainwater outflow.

[0046] When the amount of rainwater increases, the telescopic pipe 8 rises higher under the action of buoyancy, and the exposed side hole 10 can let the rainwater flow out through the side hole 10 and the outlet hole 11. When the amount of rainwater falling into the water storage tank 4 is greater than the amount of rainwater flowing out, the telescopic pipe 8 will continue to rise.

[0047] When the rainfall is stable, the amount of rainwater falling into the rainwater storage trough 4 is equal to the amount of rainwater flowing out, and at this time the expansion pipe 8 will be stable in the infiltration hole 7.

[0048] When the rainfall decreases or stops, the rainwater in the water storage trough 4 will no longer accumulate, but will flow out. Then the telescopic pipe 8 will continue to descend until the side hole 10 on the telescopic pipe 8 is completely blocked by the seepage hole 7. At this time, the rainwater in the hollow rubber ring 15 is still present. Therefore, even when the rain stops, the hollow rubber ring 15, which is stretched open by the rainwater, will still press against the sliding plate 3, and will still have a water-proof sealing function.

[0049] A side groove 12 is provided on the side wall of the seepage hole 7, and a sliding rheostat 14 is provided in the side groove 12. A metal rod 13 is fixed on the outer wall of the telescopic tube 8, which abuts against the sliding rheostat 14 and moves vertically 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 wires. The wireless sensor is also connected to the bottom end of the sliding rheostat 14 through wires. 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, it slides upward along the upper side wall of the sliding rheostat 14 with the metal rod 13, thus increasing the resistance in the circuit. When the telescopic tube 8 is stable, the resistance in the circuit remains unchanged. When the telescopic tube 8 continues to fall, the resistance in the circuit decreases.

[0051] The wireless sensor is used to process the resistance value into an electrical signal, and then transmits the corresponding electrical signal to the corresponding drive device to control the rotation speed or number of rotations of the drive device. The wireless sensor is used to convert the resistance value of the rainwater surface in the water storage tank 4 into an electrical signal, and then feeds the converted electrical signal back to the signal processing equipment to drive the drive device. This is existing technology and will not be elaborated on here.

[0052] Reference Figures 7-11 In this configuration, a fixing rod 18 is fixed inside the speaker housing body 1. A push tube 29 slides on the fixing rod 18. An end plate 19 is fixed to one end of the fixing rod 18 facing the sliding plate 3. A return spring is provided between the push tube 29 and the end plate 19 to reset the sliding plate 3. The push tube 29 is connected to the sliding plate 3 through a shaft and a connecting rod 20. Therefore, the push tube 29 slides on the fixing rod 18 towards the sliding plate 3 through the connecting rod 20, thus pushing the sliding plate 3 to move. When the push tube 29 is no longer subjected to external pushing force, the return spring can push the push tube 29 back to its original position. Therefore, under the dual action of external pushing force and return spring, the sliding plate 3 can be driven to slide back and forth inside the speaker housing body 1.

[0053] Reference Figure 9 and Figure 10 In this state, a telescopic disc 21 connected to a push tube 29 slides coaxially on a fixed rod 18, and a rotating disc 24 rotates coaxially on the fixed rod 18. A radially fixed triangular block 22 is fixed on the side of the telescopic disc 21 facing the rotating disc 24. The cross section of the triangular block 22 is an isosceles triangle. A stop rod 23 is provided on the rotating disc 24 that abuts against the triangular block 22. Therefore, as the rotating disc 24 rotates, it can carry the stop rod 23 to rotate around the fixed rod 18. Since the telescopic disc 21 is connected to the rotating disc 24, and the end of the stop rod 23 facing the telescopic disc 21 has a chamfer, it can push against the triangular block 22 on the telescopic disc 21, allowing the triangular block 22 to push against the telescopic disc 21 and slide along the axis on the fixed rod 18, thereby moving the sliding plate 3.

[0054] The speaker housing 1 contains a drive mechanism for rotating the rotating disk 24. This drive mechanism is a drive motor that drives the rotating disk 24 to rotate stably. The rotating disk 24 has radial sliding holes 26, and the abutment rod 23 slides on the radial sliding holes 26 via a sliding block 28. A drive motor 25 is located on the side wall of the rotating disk 24, and a lead screw 27 extending radially into the radial sliding holes 26 is fixed to the output end of the drive motor 25. The sliding block 28 has a threaded hole that matches the lead screw 27, and the lead screw 27 drives the sliding block 28 to slide on the radial sliding holes 26 via the threaded hole. Therefore, the electrical signal processed by the wireless sensor is transmitted to the drive motor 25 through the signal processing equipment, thereby controlling the number of rotations of the drive motor 25. That is, when the amount of rainwater increases, it can drive the abutment rod 23 to slide towards the fixed rod 18. Because the rotating disk 24 rotates under the action of the drive motor... The abutment 23 rotates, and the closer it is to the center of the rotating disk 24, the higher the frequency at which the abutment 23 pushes against the triangular block 22, causing the telescopic disk 21 to move. This creates a cycle: the more rainfall, the more the drive motor 25 rotates, driven by a wireless sensor, moving the abutment 23 closer to the fixed rod 18. This causes the sliding plate 3 to vibrate at a higher frequency, solving the problem of prolonged water accumulation at the horn of the sliding plate 3 due to heavy rainfall, and allowing the water to be ejected promptly. Conversely, when rainfall decreases, the abutment 23 moves away from the fixed rod 18, causing the sliding plate 3 to vibrate at a lower frequency. This effectively ensures that the vibration frequency of the sliding plate 3 changes with the amount of rainfall, preventing the vibration frequency from remaining high when rainfall decreases, which could easily damage the horn on the sliding plate 3.

[0055] The following implementation method is also available for addressing the vibration frequency of the sliding plate 3:

[0056] Since the speaker housing 1 is equipped with a drive motor, and the wireless sensor is used to convert the water level in the water storage tank 4 into an electrical signal by the resistance value, and then feed the converted electrical signal back to the drive motor to control the speed of the drive motor. At this time, the stop rod 23 is fixedly set on the rotating disk 24, so the vibration frequency of the sliding plate 3 can be controlled directly by adjusting the speed of the rotating disk 24.

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

[0058] First, the output end of the hydraulic cylinder assembly is connected to the bottom of the speaker housing body 1 via the shaft. Therefore, after the hydraulic cylinder assembly is opened, it can drive the speaker housing body 1 and the sliding plate 3 with the speaker to swing in the vertical plane. The inner wall of the speaker housing body 1 has an annular inner wall groove 17. The hollow rubber ring 15 is installed in the inner wall groove 17. Therefore, the hollow rubber ring 15 provides a sealing condition for the gap between the speaker housing body 1 and the sliding plate 3, which is used to prevent external rainwater from entering the speaker housing body 1 through the gap between the speaker housing body 1 and the sliding plate 3.

[0059] When rainwater collects in the water storage trough 4, it flows from the rubber hose 5 into the hollow rubber ring 15, causing the originally flat hollow rubber ring 15 to fill with water and expand. The expanded hollow rubber ring 15 exerts greater pressure on the side wall of the sliding plate 3 than the originally flat hollow rubber ring 15, making the hollow rubber ring 15, which was originally attached to the side wall of the sliding plate 3, more tightly. That is, the hollow rubber ring 15 has a better water-repellent effect on the side wall of the sliding plate 3, thus enabling the hollow rubber ring 15 to expand in rainy weather, ultimately achieving a more tightly sealed effect.

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

[0061] The wireless sensor is used to process the resistance value into an electrical signal, which is then transmitted to the corresponding drive device. The electrical signal processed by the wireless sensor is transmitted to the drive motor 25 through a signal processing device, thereby controlling the rotation frequency of the drive motor 25. Specifically, as rainfall increases, the abutment 23 slides towards the fixed rod 18. Since the rotating disk 24 rotates under the action of the drive motor, it also rotates the abutment 23. The closer to the center of the rotating disk 24, the higher the frequency at which the abutment 23 pushes against the triangular block 22, causing the telescopic disk 21 to move. Therefore, a cycle can be formed, meaning the more rainfall... By controlling the rotation number of the drive motor 25 through a wireless sensor, the abutment 23 is moved closer to the fixed rod 18, which in turn causes the sliding plate 3 to vibrate at a higher frequency. This solves the problem of water accumulating at the horn of the sliding plate 3 for too long when the rainfall is heavy, and can promptly eject the accumulated water. Conversely, when the rainfall decreases, the abutment 23 is moved away from the fixed rod 18, which causes the sliding plate 3 to vibrate at a lower frequency. Therefore, it can effectively ensure that the vibration frequency of the sliding plate 3 changes with the rainfall, and avoid the sliding plate 3 maintaining a high vibration frequency when the rainfall decreases, which could easily damage the horn on the sliding plate 3.
