Abstract
Description
Technical Field
[0001] This utility model relates to the field of broadcasting technology, specifically to a synchronous warning and directional broadcasting device based on audio detection and integrated sound and light. Background Technology
[0002] Broadcasting refers to a news dissemination tool that transmits sound via radio waves or wires. Broadcasting that transmits programs via radio waves is called wireless broadcasting, while broadcasting that transmits programs via wires is called wired broadcasting. The advantages of broadcasting are its wide reach, rapid dissemination, diverse functions, and strong persuasive power. Broadcasting is the most common form of multi-point delivery, delivering a copy of a packet to each destination station. It can be accomplished through multiple single packet deliveries or by transmitting copies of packets through individual connections until each receiver has received a copy.
[0003] However, in existing technologies, directional warnings are issued via broadcast, but the sound of a broadcast travels a long distance. When people at a distance hear a broadcast, it is difficult for them to identify the direction of the sound source and take evasive action. In noisy environments, it is also difficult to distinguish the broadcast sound. Utility Model Content
[0004] The purpose of this utility model is to provide an integrated audio-visual warning and directional broadcasting device based on audio detection, which has the advantages of lighting up the lights when broadcasting, providing synchronized audio-visual warnings, and preventing people from being unable to identify the specific location of the sound source due to being too far away, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sound-light integrated synchronous warning directional broadcasting device based on audio detection, comprising an installation component, a warning component, and a charging component. The installation component is used to mount and fix the warning component and the charging component. The warning component is disposed within the installation component for sound emission and light illumination to provide a warning. The charging component is disposed on the installation component for solar charging and powering the warning component. The warning component includes a mounting bracket, a speaker, a MUC microcontroller unit, an ADC converter, a light strip, a comparator, and a photoresistor. The mounting bracket is disposed within the installation component. The speaker is fixedly mounted on the mounting bracket. The MUC microcontroller unit is disposed within the installation component. The ADC converter is disposed within the installation component. The light strip is disposed on the warning component. The comparator is disposed within the installation component. The photoresistor is disposed on the installation component.
[0006] Furthermore, the mounting assembly includes a housing, a mounting frame, a dustproof net, two mounting posts, a bracket, and filler cotton. The mounting frame is fixedly mounted on one outer wall of the housing, the dustproof net is fixedly mounted on the inner wall of the mounting frame, both mounting posts are fixedly mounted on the outer wall of the housing, the bracket is rotatably mounted on the two mounting posts, the filler cotton is adhered to the inner wall of the housing, the mounting bracket is fixedly mounted on the inner wall of the housing, the LED strip is fixedly mounted on one outer wall of the mounting frame, the comparator is fixedly mounted on the bottom inner wall of the mounting frame, and the photoresistor is fixedly mounted on the mounting frame.
[0007] Furthermore, the shell has a hexagonal cross-section, is yellow, and the dustproof mesh is black.
[0008] Furthermore, four auxiliary rods are fixedly installed on the outer wall of the housing, and four limiting ports are opened on the bracket, with the auxiliary rods slidably connected to the limiting ports.
[0009] Furthermore, the charging assembly includes a mounting plate, a rotating rod, a fixed plate, a solar panel, two friction blocks, and a battery compartment. The mounting plate is fixedly mounted on the top of the housing, the rotating rod is rotatably mounted on the mounting plate, the fixed plate is fixedly sleeved on the rotating rod, the solar panel is fixedly mounted on the top of the fixed plate, both friction blocks are fixedly mounted on the fixed plate, the battery compartment is fixedly mounted on one inner wall of the housing, and the MUC microcontroller unit and ADC converter are both fixedly mounted on one outer wall of the battery compartment.

[0011] Furthermore, a UART interface is fixedly installed on one side of the outer wall of the housing.
[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:
[0013] This invention features a warning component that broadcasts an alert via an external microphone, transmitting the signal to a microcontroller unit (MUC). The MUC controls an ADC converter, which converts the signal and outputs two PWM signals. One signal is sent to a speaker to amplify the broadcast, while the other is sent to a comparator. When the speaker is on, the comparator activates a light strip, illuminating it. The light strip and speaker work together to provide a synchronized audio-visual warning, further enhanced by the color coordination between the housing and dustproof mesh. When the speaker stops broadcasting, the light strip turns off synchronously. The threshold can be adjusted via a UART interface to delay the light strip's shutdown. At night, a photoresistor sends a signal to the MUC when there is no sunlight, reducing the light strip's brightness. This design offers the advantages of illuminating the light during broadcasts for synchronized audio-visual warnings, preventing people from being unable to pinpoint the source of the sound from a distance.
[0014] This invention features a charging assembly. A rotating rod, which rotates on a mounting plate, simultaneously rotates a fixed plate. This fixed plate then rotates the solar panel around the rotating rod, adjusting its position to ensure it is in contact with sunlight. The solar panel generates electricity via sunlight and transmits it to the battery compartment for storage. Flipping the casing rotates the mounting column within the bracket, which in turn rotates the mounting frame, adjusting the sound propagation position. This design allows for adjustable angle solar charging, saving electricity. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] This utility model provides, for example Figures 1-6As shown, a sound-light integrated synchronous warning and directional broadcasting device based on audio detection includes a mounting component 1, a warning component 2, and a charging component 3. The mounting component 1 is used to mount and fix the warning component 2 and the charging component 3. The warning component 2 is disposed within the mounting component 1 and is used to provide a warning by emitting sound and coordinating with light. The charging component 3 is disposed on the mounting component 1 and is used for solar charging and powering the warning component 2. The warning component 2 includes a mounting bracket 201, a speaker 202, a microcontroller unit 203, an ADC converter 204, a light strip 205, a comparator 206, and a photoresistor 207. The mounting bracket 201 is disposed within the mounting component 1. The speaker 202 is fixedly mounted on the mounting bracket 201. The microcontroller unit 203 is disposed within the mounting component 1. The ADC converter 204 is disposed within the mounting component 1. The light strip 205 is disposed on the warning component 2. The comparator 206 is disposed within the mounting component 1. The photoresistor 207 is disposed on the mounting component 1. More specifically, the warning is broadcast through an external microphone and... The broadcast signal is transmitted to the MUC microcontroller 203, which controls the ADC converter 204. The ADC converter 204 converts the signal and outputs two PWM signals. One signal is transmitted to the speaker 202 to amplify the broadcast content from the external microphone. The other signal is transmitted to the comparator 206. When the speaker 202 is turned on, the comparator 206 turns on the light strip 205, causing it to illuminate. The light strip 205 and the speaker 202 work together to provide synchronized sound and light. The warning is presented visually through the color coordination of the housing 101 and the dustproof mesh 103. When the speaker 202 stops broadcasting, the light strip 205 also turns off synchronously. The threshold can be adjusted via the UART interface to delay the turning off of the light strip 205. At night, the photoresistor 207 sends a signal to the MUC microcontroller unit 203 when there is no sunlight, which reduces the brightness of the light strip 205. This system has the advantage of illuminating the light during broadcasts, providing a synchronized audio-visual warning, and preventing people from being too far away to identify the specific location of the sound source.
[0024] Additionally, the mounting assembly 1 includes a housing 101, a mounting frame 102, a dustproof net 103, two mounting posts 104, a bracket 105, and a filling cotton 106. The mounting frame 102 is fixedly mounted on one outer wall of the housing 101, the dustproof net 103 is fixedly mounted on the inner wall of the mounting frame 102, both mounting posts 104 are fixedly mounted on the outer wall of the housing 101, the bracket 105 is rotatably mounted on the two mounting posts 104, the filling cotton 106 is adhered to the inner wall of the housing 101, the mounting bracket 201 is fixedly mounted on the inner wall of the housing 101, the light strip 205 is fixedly mounted on one outer wall of the mounting frame 102, the comparator 206 is fixedly mounted on the bottom inner wall of the mounting frame 102, and the photoresistor 207 is fixedly mounted on the mounting frame 102.
[0025] In addition, the shell 101 has a hexagonal cross-section, is yellow, and the dustproof net 103 is black.
[0026] In addition, four auxiliary rods are fixedly installed on the outer wall of the housing 101, and four limiting ports are opened on the bracket 105. The auxiliary rods are slidably connected to the limiting ports.
[0027] like Figure 1 As shown, the charging assembly 3 includes a mounting plate 301, a rotating rod 302, a fixing plate 303, a solar panel 304, two friction blocks 305, and a battery compartment 306. The mounting plate 301 is fixedly mounted on the top of the housing 101. The rotating rod 302 is rotatably mounted on the mounting plate 301. The fixing plate 303 is fixedly sleeved on the rotating rod 302. The solar panel 304 is fixedly mounted on the top of the fixing plate 303. Both friction blocks 305 are fixedly mounted on the fixing plate 303. The battery compartment 306 is fixedly mounted on the inner wall of one side of the housing 101. The MUC microcontroller unit 203 and the ADC converter 204 are both fixedly mounted on one side of the battery compartment 306. More specifically, on the outer wall, rotating the rotating rod 302 causes the mounting plate 301 to rotate, which in turn drives the fixing plate 303 to rotate. The fixing plate 303 then drives the solar panel 304 to rotate around the rotating rod 302, adjusting the position of the solar panel 304 to contact the sunlight. The solar panel 304 generates electricity through the sun and transmits the electrical energy to the battery compartment 306 for storage. Flipping the housing 101 causes the mounting column 104 to rotate within the bracket 105, and the housing 101 also causes the mounting frame 102 to rotate, adjusting the sound propagation position. This allows for adjustable angle solar charging and saves electricity.
[0028] In addition, the mounting plate 301 has a U-shaped cross-section, and a knob is fixedly installed at one end of the rotating rod 302.
[0029] In some embodiments, a UART interface is fixedly installed on one outer wall of the housing 101.
[0030] Working principle:
[0031] Step 1: Adjust the installation. Rotate the rotating rod 302. The rotating rod 302 rotates on the mounting plate 301. While rotating, the rotating rod 302 also drives the fixing plate 303 to rotate. The fixing plate 303 drives the solar panel 304 to rotate around the rotating rod 302. Adjust the position of the solar panel 304 to contact the sunlight. The solar panel 304 generates electricity through the sun and transmits the electrical energy to the battery compartment 306 for storage. Flip the housing 101. The housing 101 drives the mounting column 104 to rotate. The mounting column 104 rotates within the bracket 105. The housing 101 drives the mounting frame 102 to rotate. Adjust the sound propagation position.
[0032] Step Two: Synchronous Alarm. An external microphone broadcasts an alert, transmitting the signal to the MUC microcontroller unit 203. The MUC microcontroller unit 203 controls the ADC converter 204, which converts the signal and outputs two PWM signals. One signal is transmitted to the speaker 202 to amplify the broadcast from the external microphone, and the other signal is transmitted to the comparator 206. When the speaker 202 broadcasts, the comparator 206 activates the light strip 205, causing it to illuminate. The light strip 205 and speaker 202 work together to provide a synchronized audio-visual alert. The colors of the housing 101 and dustproof mesh 103 also provide an aesthetic warning. When the speaker 202 stops broadcasting, the light strip 205 simultaneously turns off. The threshold can be adjusted via the UART interface to delay the light strip 205's shutdown. At night, the photoresistor 207 sends a signal to the MUC microcontroller unit 203 when there is no sunlight, reducing the brightness of the light strip 205.
