A modular outdoor loudspeaker and its control method

Abstract

This invention provides a modular outdoor loudspeaker device and its control method. A gasket is embedded in the inner wall of the loudspeaker near the diaphragm. A guide tube passes through the lower end of the gasket, and a water-storing ball passes through the end of the guide tube away from the gasket. Heat dissipation plates pass through both sides of the guide tube. A support is provided at the lower end of the inner wall of the water-storing ball, and a float slides through the middle of the support. When the float squeezes the rubber ball, the air inside the rubber ball is discharged through the pipe, and the pressure of the rubber ball decreases. Due to the elasticity of the rubber ball, after the rubber ball rebounds, since the internal pressure of the rubber ball is less than the external pressure, the external atmospheric pressure forces the water accumulated at the lower end of the water-storing ball into the pipe, filling the volume that lost the gas, so that the pressure inside the rubber ball is equal to the external atmospheric pressure, thus completing the intake. This facilitates the rubber ball to absorb the water accumulated at the lower end of the water-storing ball through the pipe. At this time, the water accumulation at the lower end of the water-storing ball decreases, and the float moves downward at the lower end of the support.

Description

Technical Field

[0001] This invention relates to the field of loudspeakers and microphones, specifically to a modular outdoor loudspeaker device and its control method. Background Technology

[0002] A loudspeaker, also known as a "loudspeaker," is a commonly used electroacoustic transducer. Audio electrical energy is transmitted through electromagnetic, piezoelectric, or electrostatic effects, causing the cone or diaphragm to vibrate and resonate with the surrounding air to produce sound. Loudspeakers are installed outdoors with bolts to propagate sound. This article provides technical insights into loudspeakers.

[0003] The study of loudspeaker devices revealed the following problems:

[0004] Since loudspeakers are usually assembled and installed outdoors for a long time, the outdoor environment can cause the loudspeaker casing to age faster. As the loudspeaker casing ages, the gaps between the casings tend to increase. When the gaps at the joints of the loudspeaker casings increase, water can easily enter the loudspeaker through the gaps between the casings, which can easily damage the electronic components inside the loudspeaker.

[0005] Currently, the prior art CN202210938201.0 Modular Speaker and Modular Sound Reproduction System discloses a speaker. The modular speaker of this invention allows a rear module and a front module selected from multiple modules to be applied to and removed from the main module, thereby enhancing its versatility. In the implementation of the modular speaker, the rear module may have a front end operatively connected to the main module, and the front module may have a rear end operatively connected to the main module.

[0006] This invention primarily solves the problem that loudspeaker devices cannot prevent water from entering the interior through the gaps at the joints. Summary of the Invention

[0007] The purpose of this invention is to provide a modular outdoor loudspeaker device and its control method.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A modular outdoor loudspeaker and its control method are disclosed, comprising a loudspeaker with a diaphragm and a mounting base at each end, wherein a Bluetooth module and a control module are disposed inside the mounting base.

[0010] As a further embodiment of the present invention: the mounting base has through bolts, and the speaker is mounted and fixed through the mounting base.

[0011] As a further aspect of the present invention: the diaphragm is disposed on the front of the speaker, and a sound outlet hole is provided through the outer side of the diaphragm. A groove is provided at one end of the speaker near the diaphragm, and the groove is circular. A rotating cleaning and scraping mechanism is provided at the end of the speaker near the diaphragm.

[0012] As a further aspect of the present invention: the Bluetooth module and the control module are connected via a wire circuit, and the control module is connected to the speaker circuit via a wire circuit.

[0013] As a further aspect of the present invention: the cleaning mechanism includes a slider, a first connecting rod, a sliding cylinder, a cleaning ring, and a second connecting rod. The slider slides inside the groove of the horn. The first connecting rod and the second connecting rod are respectively connected to the slider. The sliding cylinder slides through the outside of the first connecting rod and the second connecting rod. The cleaning ring swings at the connection end of the first connecting rod and the second connecting rod.

[0014] As a further aspect of the present invention: the slider slides at both ends of the slide groove of the horn, and the first connecting rod and the second connecting rod are respectively connected to the sliders at both ends of the slide groove, and the slider slides 360° inside the slide groove.

[0015] As a further aspect of the present invention: both the first connecting rod and the second connecting rod are inclined at 15-25°. When the first connecting rod is at the upper end of the cleaning ring, the slide cylinder slides down to the lower end of the first connecting rod.

[0016] As a further aspect of the present invention: the cleaning ring is located outside the vibrating diaphragm, and when the cleaning ring rotates, the cleaning ring rotates and fits against the side of the vibrating diaphragm.

[0017] As a further aspect of the present invention: the slide tube is cylindrical, and slides vertically inclinedly on the outside of the first connecting rod and the second connecting rod respectively.

[0018] As a further aspect of the present invention: a gasket is embedded in the inner wall of the horn near the diaphragm, a guide tube passes through the lower end of the gasket, a water storage ball passes through the end of the guide tube away from the gasket, heat dissipation plates pass through both sides of the guide tube, a bracket is provided at the lower end of the inner wall of the water storage ball, a float slides through the middle of the bracket, a rubber ball is embedded in the upper part of the inside of the water storage ball, a sponge block is embedded in the upper part of the inside of the rubber ball, and a pipe passes through the upper part of the side of the rubber ball.

[0019] As a further embodiment of the present invention: the gasket is located at the connecting end of the horn shell, the gasket is concave, the gasket is semi-circular, the semi-circular angle is 90-180°, and the gasket is connected to the water storage ball through the guide pipe.

[0020] As a further embodiment of the present invention: the guide tube is inclined downward at 25-45°, the heat sink plate is connected to the upper end of the guide tube, and the upper end of the heat sink plate has multiple holes with a diameter of 0.2-0.5cm.

[0021] As a further aspect of the present invention: the middle of the support is cylindrical, and the upper end of the side of the water storage ball is connected to the guide pipe.

[0022] As a further aspect of the present invention: the buoy weighs 2-5g, the buoy is hollow inside, the buoy is less than 1cm away from the rubber ball, and the lower end of the buoy is 2-3cm away from the lower end of the water storage ball.

[0023] As a further aspect of the present invention: the lower end of the pipe extends to the lower end of the water storage ball, the sponge block inside the rubber ball is V-shaped, and the rubber ball is made of rubber.

[0024] As a further aspect of the present invention, the control method includes the following steps, the specific operation steps of which are as follows:

[0025] S1: The speaker is installed and fixed outdoors via a mounting base. A control chip is located on the side of the control module, and the control module is connected to an external control terminal via a loop, which facilitates the external control terminal to transmit commands to the inside of the control module. Subsequently, the control module controls the speaker to turn on, enabling this type of speaker device to form a modular control.

[0026] S2: When it is windy outdoors, the wind force is used, and the first and second links are both tilted at 15-25°. Therefore, the gravity at both ends of the cleaning ring is unstable. At this time, the cleaning ring can easily rotate and clean on the outside of the vibrating diaphragm, while the slider slides synchronously inside the horn's groove.

[0027] S3: When the first or second link swings from bottom to top to the upper end of the cleaning ring, the slide can quickly slide downward on the outer side of the first or second link, further assisting the first or second link at the upper end of the cleaning ring to swing downward, thereby assisting the cleaning ring to further clean the outer side of the diaphragm, avoiding the situation where dust adheres to the outer side of the diaphragm after the speaker is installed outdoors, thus causing the speaker's sound outlet to be blocked.

[0028] S4: The gasket is located at the joint of the horn shell. Therefore, when water leaks at the joint of the horn shell, the water first enters the upper part of the gasket. The water then enters the interior of the guide tube through the gasket. The guide tube directs the water to the interior of the water storage ball. Since the lower end of the float is 2-3cm away from the lower end of the interior of the water storage ball, when the water level at the lower end of the interior of the water storage ball is greater than 2-3cm, the float will slide upward on the inside of the bracket using the buoyancy of the water.

[0029] S5: When the buoy continues to slide upward, the buoy and the rubber ball are less than 1cm apart. When the buoy slides upward, it is convenient for the buoy to quickly squeeze the lower end of the rubber ball. The lower end of the rubber ball deforms. When the buoy squeezes the rubber ball, the air inside the rubber ball is discharged through the pipe, and the pressure of the rubber ball decreases.

[0030] S6: Utilizing the resilience of the rubber ball, after the rubber ball rebounds, since the internal pressure of the rubber ball is less than the external pressure, the external atmospheric pressure forces the water accumulated at the bottom of the water storage ball into the pipe, filling the volume that lost gas, so that the pressure inside the rubber ball is equal to the external atmospheric pressure, thus completing the suction. This makes it convenient for the rubber ball to draw in the water accumulated at the bottom of the water storage ball through the pipe. At this time, the water accumulation at the bottom of the water storage ball decreases, so the float moves downward at the bottom of the support.

[0031] S7: When there is too much water inside the water storage ball, the water inside the water storage ball flows back into the inside of the guide tube. When there is too much water inside the guide tube, the water can enter the inside of the heat sink for collection, preventing the water from flowing back into the inside of the gasket.

[0032] Beneficial effects

[0033] 1. When the wind blows outdoors, the present invention utilizes the wind force, and both the first and second connecting rods are tilted at 15-25°, so the gravity at both ends of the cleaning ring is unstable. At this time, the cleaning ring can easily rotate and clean on the outside of the vibrating diaphragm, while the slider slides synchronously inside the groove of the horn.

[0034] 2. When the first or second link of the present invention swings from bottom to top to the upper end of the cleaning ring, the slide can quickly slide downward on the outer side of the first or second link, further assisting the first or second link at the upper end of the cleaning ring to swing downward, thereby assisting the cleaning ring to further clean the outer side of the diaphragm, avoiding the situation where dust adheres to the outer side of the diaphragm after the speaker is installed outdoors, thus causing the speaker's sound outlet to be blocked.

[0035] 3. The gasket of this invention is located at the joint end of the horn shell. Therefore, when water seeps into the joint of the horn shell, the water first enters the upper end of the gasket. The water then enters the interior of the guide tube through the gasket. The guide tube guides the water to the interior of the water storage ball. Since the lower end of the float is 2-3cm away from the lower end of the interior of the water storage ball, when the water height at the lower end of the interior of the water storage ball is greater than 2-3cm, the float uses the buoyancy of the water to slide upward on the inner side of the bracket.

[0036] 4. When the buoy of this invention continues to slide upward, the distance between the buoy and the rubber ball is less than 1 cm. When the buoy slides upward, it is convenient for the buoy to quickly squeeze to the lower end of the rubber ball. The lower end of the rubber ball deforms. When the buoy squeezes the rubber ball, the air inside the rubber ball is discharged through the pipe, and the pressure of the rubber ball decreases. Taking advantage of the elasticity of the rubber ball, after the rubber ball rebounds, since the internal pressure of the rubber ball is less than the external pressure, the external atmospheric pressure forces the water accumulated at the lower end of the water storage ball into the pipe, filling the volume that lost the gas. This makes the pressure inside the rubber ball equal to the external atmospheric pressure, thus completing the suction. This makes it convenient for the rubber ball to absorb the water accumulated at the lower end of the water storage ball through the pipe. At this time, the water accumulation at the lower end of the water storage ball decreases, and the buoy moves downward at the lower end of the support.

[0037] 5. When there is too much water inside the water storage ball, the water inside the water storage ball flows back into the inside of the guide pipe. When there is too much water inside the guide pipe, the water can enter the inside of the heat sink plate for collection, preventing the water from flowing back into the inside of the gasket. The upper end of the heat sink plate has multiple holes with a diameter of 0.2-0.5cm. Since the heat sink plate is located inside the speaker, the water can absorb the heat inside the speaker after entering the heat sink plate, thereby reducing the internal temperature of the speaker.

[0038] 6. Since horns are usually assembled from parts, collecting water at the joints using the above steps can prevent water from entering the horn through the gaps between the outer shells when the horn is installed outdoors for a long time, thus further increasing the waterproofness of the horn shell joints.

Detailed Implementation

[0049] Please see Figure 1-9 In the embodiments of the present invention,

[0050] Example 1: A modular outdoor loudspeaker and its control method, including a loudspeaker 1, with a diaphragm 101 and a mounting base 102 at both ends of the loudspeaker 1, and a Bluetooth module 103 and a control module 104 inside the mounting base 102.

[0051] Among them: the speaker 1 is mounted on the base 102, and the mounting base 102 has a through bolt, and the speaker 1 is mounted and fixed by the mounting base 102;

[0052] A diaphragm 101 is provided on the front of the speaker 1. A sound outlet hole is provided through the outer side of the diaphragm 101. A groove is provided at one end of the speaker 1 near the diaphragm 101. The groove is circular. A rotating cleaning scraping mechanism is provided at the end of the speaker 1 near the diaphragm 101.

[0053] A sound outlet hole extends through the outer side of the diaphragm 101, and the speaker 1 emits sound through the sound outlet hole;

[0054] Bluetooth module 103 and control module 104 are connected by a wire loop, and control module 104 is connected to speaker 1 by a wire loop.

[0055] Bluetooth module 103 is a PCBA board with integrated Bluetooth functionality;

[0056] A control chip is provided on the side of the control module 104, and the control module 104 is connected to an external control terminal circuit.

[0057] The speaker 1 is installed and fixed outdoors via the mounting base 102. A control chip is provided on the side of the control module 104, and the control module 104 is connected to the external control terminal via a loop, so that the external control terminal can transmit instructions to the inside of the control module 104. Then the control module 104 controls the speaker 1 to turn on, so that this kind of loudspeaker can form a modular control.

[0058] Example 2: Refer to the attached instruction manual Figure 1-3 It can be seen that the difference between Embodiment 2 and Embodiment 1 is that the cleaning mechanism includes a slider 2, a first connecting rod 201, a sliding cylinder 202, a cleaning ring 203, and a second connecting rod 204. The slider 2 slides inside the groove of the horn 1. The first connecting rod 201 and the second connecting rod 204 are respectively connected to the slider 2. The sliding cylinder 202 slides through the outside of the first connecting rod 201 and the second connecting rod 204. The cleaning ring 203 swings at the connecting end of the first connecting rod 201 and the second connecting rod 204.

[0059] Wherein: slider 2 slides at both ends of the groove of horn 1, and the first connecting rod 201 and the second connecting rod 204 are respectively connected to slider 2 at both ends of the groove, and slider 2 slides 360° inside the groove;

[0060] The first connecting rod 201 and the second connecting rod 204 are respectively connected to the sliders 2 at both ends of the slide groove. Please refer to the instruction manual appendix. Figure 1 As shown;

[0061] The first link 201 and the second link 204 are both inclined at 15-25°. When the first link 201 is at the upper end of the cleaning ring 203, the slide cylinder 202 slides down to the lower end of the first link 201.

[0062] Both the first link 201 and the second link 204 are inclined at 15-25°. When the first link 201 or the second link 204 is at the upper end of the cleaning ring 203, the gravity at both ends of the cleaning ring 203 is unstable, which makes it convenient for the cleaning ring 203 to rotate for cleaning.

[0063] When the first connecting rod 201 is at the upper end of the cleaning ring 203, the slide cylinder 202 slides downward to the lower end of the first connecting rod 201. (Refer to the instruction manual appendix for details.) Figure 3 As shown;

[0064] The cleaning ring 203 is located on the outside of the vibrating diaphragm 101. When the cleaning ring 203 rotates, it rotates and fits against the side of the vibrating diaphragm 101.

[0065] Slide cylinder 202 is cylindrical and slides vertically inclinedly on the outside of the first connecting rod 201 and the second connecting rod 204 respectively.

[0066] When it is windy outdoors, the wind force is used, and the first link 201 and the second link 204 are both tilted at 15-25°. Therefore, the gravity at both ends of the cleaning ring 203 is unstable. At this time, the cleaning ring 203 can rotate and clean conveniently on the outside of the vibrating diaphragm 101, while the slider 2 slides synchronously inside the groove of the horn 1.

[0067] When the first link 201 or the second link 204 swings from bottom to top to the upper end of the cleaning ring 203, the slide cylinder 202 can quickly slide downward on the outer side of the first link 201 or the second link 204, further assisting the first link 201 or the second link 204 at the upper end of the cleaning ring 203 to swing downward, thereby assisting the cleaning ring 203 to further clean the outer side of the diaphragm 101, avoiding the situation where dust adheres to the outer side of the diaphragm 101 after the speaker 1 is installed outdoors, thus causing the speaker 1's sound outlet to be blocked;

[0068] Example 3: Refer to the appendix of the instruction manual Figure 1 , 4 -9 It can be seen that the difference between Embodiment 3 and Embodiments 1 and 2 is that a gasket 3 is embedded in the inner wall of the speaker 1 near the vibrating diaphragm 101, a guide tube 301 is passed through the lower end of the gasket 3, a water storage ball 4 is passed through the end of the guide tube 301 away from the gasket 3, a heat dissipation plate 302 is passed through both sides of the guide tube 301, a support 401 is provided at the lower end of the inner wall of the water storage ball 4, a float 402 is slidably passed through the middle of the support 401, a rubber ball 403 is embedded in the upper end of the inside of the water storage ball 4, a sponge block 405 is embedded in the upper end of the inside of the rubber ball 403, and a pipe 404 is passed through the upper end of the side of the rubber ball 403.

[0069] Among them: gasket 3, gasket 3 is located at the connecting end of the outer shell of speaker 1, gasket 3 is concave, gasket 3 is semi-circular, the semi-circular angle is 90-180°, and gasket 3 is connected to water storage ball 4 through guide pipe 301.

[0070] The gasket 3 is located at the joint of the speaker 1 housing. Therefore, when water leaks at the joint of the speaker 1 housing, the water first enters the upper part of the gasket 3, which can prevent water from entering the interior of the speaker 1 and causing damage to the internal electronic components of the speaker 1.

[0071] The heat dissipation tube 301 and the heat sink 302 are arranged in a downward inclination of 25-45°. The heat sink 302 is connected to the upper end of the heat dissipation tube 301. The upper end of the heat sink 302 has multiple holes with a diameter of 0.2-0.5cm.

[0072] The upper end of the heat sink 302 has multiple holes with a diameter of 0.2-0.5cm. Since the heat sink 302 is located inside the speaker 1, when water enters the heat sink 302, the water can absorb the heat inside the speaker 1, thereby reducing the internal temperature of the speaker 1.

[0073] The heat sink 302 is connected to the upper end of the guide tube 301. When too much water accumulates inside the guide tube 301, the water can enter the heat sink 302 for collection, preventing the water from flowing back into the gasket 3.

[0074] The water storage ball 4 and the support 401 are cylindrical in the middle, and the upper end of the side of the water storage ball 4 is connected to the guide pipe 301.

[0075] The middle of the support 401 is cylindrical, which facilitates the vertical sliding of the buoy 402 inside the water storage ball 4;

[0076] Buoy 402 weighs 2-5g and is hollow inside. Buoy 402 is less than 1cm away from rubber ball 403 and the lower end of buoy 402 is 2-3cm away from the lower end of the water storage ball 4.

[0077] The lower end of the buoy 402 is 2-3cm away from the lower end of the inside of the water storage ball 4. Therefore, when the water level at the lower end of the inside of the water storage ball 4 is greater than 2-3cm, the buoy 402 will slide upward on the inside of the bracket 401 using the buoyancy of the accumulated water.

[0078] The buoy 402 is hollow inside, which makes it easy for the buoy 402 to float upward using the buoyancy of the water flow;

[0079] The buoy 402 and the rubber ball 403 are less than 1cm apart. When the buoy 402 slides upward, it is convenient for the buoy 402 to quickly squeeze to the lower end of the rubber ball 403, and the lower end of the rubber ball 403 will deform.

[0080] Rubber ball 403 and pipe 404, the lower end of pipe 404 extends to the lower end of the water storage ball 4, the sponge block 405 inside rubber ball 403 is "V" shaped, and rubber ball 403 is made of rubber.

[0081] The sponge block 405 can absorb the water inside the rubber ball 403, preventing the water from flowing back into the water storage ball 4 through the pipe 404.

[0082] When the buoy 402 squeezes the rubber ball 403, the air inside the rubber ball 403 is discharged through the pipe 404, and the pressure of the rubber ball 403 decreases. Taking advantage of the elasticity of the rubber ball 403, after the rubber ball 403 rebounds, since the internal pressure of the rubber ball 403 is less than the external pressure, the external atmospheric pressure forces the water accumulated at the lower end of the water storage ball 4 into the pipe, filling the volume that lost the air, so that the pressure inside the rubber ball 403 is equal to the external atmospheric pressure, thus completing the suction. This utilizes the pressure difference, which can be referred to as the water suction principle of a dropper.

[0083] Wherein: Gasket 3 is located at the connecting end of the horn 1 shell, so when water seeps at the connecting end of the horn 1 shell, the water first enters the upper end of gasket 3, and the water enters the interior of the guide pipe 301 through gasket 3. The guide pipe 301 guides the water to the interior of the water storage ball 4. Since the lower end of the float 402 is 2-3cm away from the lower end of the interior of the water storage ball 4, when the water height at the lower end of the interior of the water storage ball 4 is greater than 2-3cm, the float 402 uses the buoyancy of the water to slide upward on the inner side of the bracket 401.

[0084] As the buoy 402 continues to slide upward, with the buoy 402 and the rubber ball 403 spaced less than 1 cm apart, the buoy 402 can quickly squeeze to the lower end of the rubber ball 403. The lower end of the rubber ball 403 deforms. When the buoy 402 squeezes the rubber ball 403, the air inside the rubber ball 403 is discharged through the pipe 404, and the pressure of the rubber ball 403 decreases. Taking advantage of the elasticity of the rubber ball 403, after the rubber ball 403 rebounds, since the internal pressure of the rubber ball 403 is less than the external pressure, the external atmospheric pressure forces the water accumulated at the lower end of the water storage ball 4 into the pipe, filling the volume that lost the gas. This makes the pressure inside the rubber ball 403 equal to the external atmospheric pressure, thus completing the suction. This allows the rubber ball 403 to absorb the water accumulated at the lower end of the water storage ball 4 through the pipe 404. At this time, the water accumulation at the lower end of the water storage ball 4 decreases, and the buoy 402 moves downward at the lower end of the support 401.

[0085] When there is too much water inside the water storage ball 4, the water inside the water storage ball 4 flows back into the guide pipe 301. When there is too much water inside the guide pipe 301, the water can enter the heat sink 302 for collection, preventing the water from flowing back into the gasket 3. The upper end of the heat sink 302 has multiple holes with a diameter of 0.2-0.5cm. Since the heat sink 302 is located inside the speaker 1, the water can absorb the heat inside the speaker 1 after entering the heat sink 302, thereby reducing the internal temperature of the speaker 1.

[0086] Example 4: The control method includes the following steps, and the specific operation steps are as follows:

[0087] S1: The speaker 1 is installed and fixed outdoors via the mounting base 102. The control module 104 has a control chip on its side and is connected to an external control terminal via a loop, so that the external control terminal can transmit commands to the inside of the control module 104. Then the control module 104 controls the speaker 1 to turn on, so that this kind of speaker device can form a modular control.

[0088] S2: When it is windy outdoors, the wind force is used, and the first link 201 and the second link 204 are both tilted at 15-25°. Therefore, the gravity at both ends of the cleaning ring 203 is unstable. At this time, the cleaning ring 203 can rotate and clean easily on the outside of the vibrating diaphragm 101, while the slider 2 slides synchronously inside the groove of the horn 1.

[0089] S3: When the first link 201 or the second link 204 swings from bottom to top to the upper end of the cleaning ring 203, the slide cylinder 202 can quickly slide downward on the outer side of the first link 201 or the second link 204, further assisting the first link 201 or the second link 204 at the upper end of the cleaning ring 203 to swing downward, thereby assisting the cleaning ring 203 to further clean the outer side of the diaphragm 101, avoiding the situation where dust adheres to the outer side of the diaphragm 101 after the speaker 1 is installed outdoors, thus causing the speaker 1's sound outlet to be blocked;

[0090] S4: The gasket 3 is located at the connection end of the horn 1 housing. Therefore, when water seeps into the connection of the horn 1 housing, the water first enters the upper end of the gasket 3. The water then enters the interior of the guide pipe 301 through the gasket 3. The guide pipe 301 guides the water to the interior of the water storage ball 4. Since the lower end of the float 402 is 2-3cm away from the lower end of the interior of the water storage ball 4, when the water height at the lower end of the interior of the water storage ball 4 is greater than 2-3cm, the float 402 uses the buoyancy of the water to slide upward on the inside of the bracket 401.

[0091] S5: When the buoy 402 continues to slide upward, the buoy 402 and the rubber ball 403 are less than 1cm apart. When the buoy 402 slides upward, it is convenient for the buoy 402 to quickly squeeze the lower end of the rubber ball 403. The lower end of the rubber ball 403 is deformed. When the buoy 402 squeezes the rubber ball 403, the air inside the rubber ball 403 is discharged through the pipe 404, and the pressure of the rubber ball 403 decreases.

[0092] S6: Utilizing the resilience of the rubber ball 403, after the rubber ball 403 rebounds, since the internal pressure of the rubber ball 403 is less than the external pressure, the external atmospheric pressure forces the water accumulated at the lower end of the water storage ball 4 into the pipe, filling the volume that has lost gas, so that the pressure inside the rubber ball 403 is equal to the external atmospheric pressure, thus completing the suction. This makes it convenient for the rubber ball 403 to absorb the water accumulated at the lower end of the water storage ball 4 through the pipe 404. At this time, the water accumulation at the lower end of the water storage ball 4 decreases, so the float 402 moves downward at the lower end of the support 401.

[0093] S7: When there is too much water inside the water storage ball 4, the water inside the water storage ball 4 flows back into the guide pipe 301. When there is too much water inside the guide pipe 301, the water can enter the heat sink 302 for collection, preventing the water from flowing back into the gasket 3.

[0094] Since the speaker 1 is usually assembled, collecting the water at the joints of the speaker 1 using the above steps can prevent water from entering the speaker 1 through the gaps between the shells when the joints of the speaker 1 shells increase due to long-term outdoor installation. This can further increase the waterproofness of the joints of the speaker 1 shells.

[0095] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.

4. A modular outdoor loudspeaker device according to claim 1, characterized in that: The lower end of the pipe (404) extends to the lower end of the water storage ball (4), and the sponge block (405) inside the rubber ball (403) is V-shaped.

5. A control method for a modular outdoor loudspeaker, characterized in that: According to any one of claims 1-4, the control method of a modular outdoor loudspeaker includes the following steps: S1: The speaker (1) is installed and fixed outdoors via the mounting base (102). A control chip is provided on the side of the control module (104), and the control module (104) is connected to the external control terminal loop, so that the external control terminal can transmit the command to the inside of the control module (104). Then the control module (104) controls the speaker (1) to turn on, so that the speaker device can form a modular control. S2: When it is windy outdoors, the wind force is used, and the first link (201) and the second link (204) are both tilted at 15-25°. Therefore, the gravity at both ends of the cleaning ring (203) is unstable. At this time, the cleaning ring (203) can rotate and clean conveniently on the outside of the vibrating diaphragm (101), while the slider (2) slides synchronously inside the groove of the horn (1). S3: When the first link (201) or the second link (204) swings from bottom to top to the upper end of the cleaning ring (203), the slide (202) can quickly slide downward on the outer side of the first link (201) or the second link (204), further assisting the first link (201) or the second link (204) at the upper end of the cleaning ring (203) to swing downward, thereby assisting the cleaning ring (203) to further clean the outer side of the diaphragm (101), avoiding the situation where dust adheres to the outer side of the diaphragm (101) after the speaker (1) is installed outdoors, thus causing the speaker (1) sound outlet hole to be blocked; S4: The gasket (3) is located at the connection end of the horn (1) shell. Therefore, when water seeps into the connection of the horn (1) shell, the water first enters the upper end of the gasket (3). The water enters the interior of the guide pipe (301) through the gasket (3). The guide pipe (301) guides the water to the interior of the water storage ball (4). Since the lower end of the float (402) is 2-3cm away from the lower end of the interior of the water storage ball (4), when the water height at the lower end of the interior of the water storage ball (4) is greater than 2-3cm, the float (402) uses the buoyancy of the water to slide upward on the inside of the bracket (401). S5: When the buoy (402) continues to slide upward, the buoy (402) and the rubber ball (403) are less than 1cm apart. When the buoy (402) slides upward, it is convenient for the buoy (402) to quickly squeeze to the lower end of the rubber ball (403). The lower end of the rubber ball (403) deforms. When the buoy (402) squeezes the rubber ball (403), the air inside the rubber ball (403) is discharged through the pipe (404), and the pressure of the rubber ball (403) decreases. S6: Utilizing the resilience of the rubber ball (403), after the rubber ball (403) rebounds, since the internal pressure of the rubber ball (403) is less than the external pressure, the external atmospheric pressure forces the water accumulated at the lower end of the water storage ball (4) into the pipe, filling the volume that has lost gas, so that the pressure inside the rubber ball (403) is equal to the external atmospheric pressure, thus completing the suction, thereby facilitating the rubber ball (403) to absorb the water accumulated at the lower end of the water storage ball (4) through the pipe (404). At this time, the water accumulation at the lower end of the water storage ball (4) decreases, thus the float (402) moves downward at the lower end of the support (401); S7: When there is too much water inside the water storage ball (4), the water inside the water storage ball (4) flows back to the inside of the guide pipe (301). When there is too much water inside the guide pipe (301), the water can enter the inside of the heat sink (302) for collection, thus preventing the water from flowing back to the inside of the gasket (3).
