It should be noted that when an element is described as "connected" to another element, it can be directly connected to the other element, or there can be one or more intermediate elements therebetween.

[0043] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0044] The present application embodiment provides a lighting control system. Figure 1 The lighting control system 100 includes an audio system 10 and a terminal device 20 .

[0045] The sound system 10 is in communication connection with the terminal device 20 . The sound system 10 is the core of the lighting control system 100 . It can play audio and emit light according to the live human voice, and can also play audio and emit light according to the digital audio data sent by the terminal device 20 .

[0046] The terminal device 20 is connected to the sound system 10 for transmitting digital audio data to the sound system 10. The terminal device 20 may be any suitable type of electronic device, such as a mobile phone, a tablet computer, a laptop computer, a watch, a vehicle-mounted device, a virtual reality device, an augmented reality device, etc.

[0047] In some embodiments, Figure 1 As shown, the audio system 10 includes a microphone 11 and a speaker 12 .

[0048] The microphone 11 is a sound input device for collecting any sound such as human voice, environmental sound, etc. Figure 2 The microphone 11 includes a microphone transmitting plate 111 and a first light emitting module 112 .

[0049] The microphone transmitting board 111 is electrically connected to the first light emitting module 112, and is used to collect and process sound to obtain a first light control signal, and control the first light emitting module 112 to emit light according to the first light control signal. When the first light emitting module 112 emits light according to the first light control signal, the first light emitting module 112 can emit light in any light emitting mode, including brightness, color, flashing frequency or a combination thereof.

[0050] like Figure 2 As shown, the speaker 12 includes a microphone receiver 121 , a speaker main control board 122 and a second light emitting module 123 .

[0051] The microphone receiver 121 is electrically connected to the audio main control board 122 and is in communication connection with the microphone transmitting board 111 , and is used for receiving a first light control signal sent by the microphone transmitting board 111 and forwarding the first light control signal to the audio main control board 122 .

[0052] The audio main control board 122 is electrically connected to the second light emitting module 123 for receiving the first light control signal forwarded by the microphone receiver 121 and outputting the first light control signal to the second light emitting module 123 , thereby controlling the second light emitting module 123 to emit light according to the first light control signal.

[0053] Therefore, this embodiment can realize that the microphone 11 and the speaker 12 are illuminated in conjunction with the sound, which enriches the illumination mode of the sound system 10 and is conducive to improving the on-site atmosphere.

[0054] In some embodiments, see Figure 3 The microphone transmitting board 111 includes a sound collecting circuit 1111 , a signal processing circuit 1112 and a first wireless communication module 1113 .

[0055] The sound collection circuit 1111 is used to collect sound to obtain an electrical signal. The electrical signal is an analog signal containing sound information, and the signal strength of the electrical signal is usually weak.

[0056] In some embodiments, the sound collection circuit 1111 is an electret microphone. The basic principle of the electret microphone is to convert a mechanical signal (sound signal) into an electrical signal by changing the capacitance of a variable capacitor as the sound vibrates. The electret microphone is a passive device and does not have the ability to directly output a voltage (current) signal, so a DC bias needs to be added to it to allow it to output a voltage signal.

[0057] The signal processing circuit 1112 is electrically connected to the sound collection circuit 1111, and is used to process the electrical signal to obtain the first light control signal. In some embodiments, the signal processing circuit 1112 can obtain the first light control signal in digital form after appropriately processing the weak analog electrical signal, or can obtain audio data in digital form after appropriately processing the weak analog electrical signal, wherein the audio data is the audio data used by the audio 20 to play the live human voice in real time.

[0058] The first wireless communication module 1113 is electrically connected to the signal processing circuit 1112 and is communicatively connected to the microphone receiver 121, and is used to send a first light control signal to the microphone receiver 121, so that the microphone receiver 121 forwards the first light control signal to the audio main control board 122. At this time, the audio main control board 122 can realize light control of the first light module 112.

[0059] It is understandable that the first wireless communication module 1113 can also send the audio data sent by the signal processing circuit 1112 to the microphone receiver 121, so that the microphone receiver 121 forwards the audio data to the audio main control board 122, and the audio main control board 122 can play audio according to the audio data.

[0060] In some embodiments, the first wireless communication module 1113 may use any suitable type of wireless communication technology, such as Bluetooth, Wi-Fi, etc.

[0061] In some embodiments, Figure 3 As shown, the signal processing circuit 1112 includes an amplifier circuit 11121 , an analog-to-digital conversion circuit 11122 and a first controller 11123 .

[0062] The amplifier circuit 11121 is electrically connected to the sound collection circuit 1111 and is used to amplify the electrical signal.

[0063] In some embodiments, the amplifier circuit 11121 is an integrated operational amplifier. The integrated operational amplifier can be constructed in any form, for example, the integrated operational amplifier is an LM386 chip, which is an audio integrated amplifier, a power amplifier with the advantages of low power consumption, adjustable internal chain gain, wide power supply voltage range, few external components and low total harmonic distortion, and is widely used in recorders and radios.

[0064] The analog-to-digital conversion circuit 11122 is electrically connected to the amplifier circuit 11121 and is used to convert the amplified electrical signal into a digital signal for subsequent digital processing. The digital signal output by the analog-to-digital conversion circuit 11122 is a sound signal, which is a time domain signal.

[0065] The first controller 11123 is electrically connected to the analog-to-digital conversion circuit 11122 and is used for processing the digital signal to obtain a first light control signal.

[0066] Since the sound signal output by the analog-to-digital conversion circuit 11122 is a one-dimensional time domain signal, it is impossible to observe how the frequency of the sound changes over time. Therefore, in order to observe the frequency components of the sound, the first controller 11123 can transform the time domain signal into the frequency domain through any suitable method such as Fourier transform to obtain a sound spectrum. The sound spectrum refers to the energy distribution of the sound at each frequency and can be used to analyze the composition and characteristics of the sound. The first controller 11123 then generates a first lighting control signal based on the sound spectrum.

[0067] The first controller 11123 may also process the digital signal output by the analog-to-digital conversion circuit 11122 to obtain audio data, and then control the first wireless communication module 1113 to send the audio data to the microphone receiver 121 .

[0068] In order to reduce the amount of audio data and the channel bandwidth required for transmission and maintain the high quality of the input sound, the first controller 11123 can use any suitable encoding algorithm such as RLE (run-length encoding) to compress the audio data into an audio code stream, and then send the audio code stream corresponding to the audio data to the microphone receiver 121 through the first wireless communication module 1113.

[0069] In some embodiments, the first controller 11123 includes an I2S (Inter-IC Sound) interface, a first AUX interface (Auxiliary) and a first SPI (Serial Peripheral Interface) interface.

[0070] The I2S interface is a serial interface standard widely used in digital audio transmission, which can provide high-quality audio signal transmission. The I2S interface includes a clock signal line (Clock), a data signal line (Data), and a synchronization signal line (Sync). The clock signal line is used to transmit the clock signal, which is used to control the timing of the I2S interface. The data signal line is used to transmit the audio signal, and the synchronization signal line is used to transmit the synchronization signal, which is used to mark the beginning and end of a frame of audio data.

[0071] The first AUX interface (Auxiliary) is an audio input interface. The first controller 11123 can receive audio data through the first AUX interface.

[0072] The first SPI interface is used to connect the first controller 11123 and the first light-emitting module 112. The first SPI interface is a synchronous peripheral interface, which enables the first controller 11123 and the first light-emitting module 112 to communicate in a serial manner to exchange information, thereby driving the first light-emitting module 112 to emit light.

[0073] In some embodiments, the first light emitting module 112 is a colorful light panel.

[0074] See also Figure 4 The first light emitting module 112 includes a first light driving board 1121 , a first annular colorful light strip 1122 and a first rectangular colorful light strip 1123 .

[0075] The first light driving board 1121 is electrically connected to the microphone transmitting board 111, and is used to generate a first light driving signal in response to a first light control signal. The first light driving signal may be a driving voltage / driving current.

[0076] The first annular colorful light strip 1122 is electrically connected to the first light driving board 1121, and is used to emit light under the drive of the second light driving signal. In some embodiments, the first annular colorful light strip 1122 includes a plurality of LED lamp beads, each of which is electrically connected to the first light driving board 1121, and the first light driving board 1121 can control the driving voltage / driving current of each LED lamp bead respectively to control the color, brightness and other light-emitting modes of each LED lamp bead.

[0077] The first rectangular colorful light strip 1123 is electrically connected to the first light driving board 1121, and is used to emit light under the drive of the second light driving signal. The number of the first rectangular colorful light strip 1123 can be one or more. Figure 4 As shown, the number of the first rectangular colorful light strips 1123 is 2.

[0078] The first annular fantasy light strip 1122 and the first rectangular fantasy light strip 1123 can be set at any position on the first light driving board 1121. For example, the first annular fantasy light strip 1122 is set at a roughly central position of the first light driving board 1121, and the first rectangular fantasy light strip 1123 is set inside the first annular fantasy light strip 1122.

[0079] Therefore, the present embodiment uses various shapes of colorful light strips for combined lighting, which is beneficial to enhancing the lighting effect of the first light-emitting module 112 .

[0080] In some embodiments, please refer to Figure 3 The microphone receiver 121 includes a second wireless communication module 1211 and a second controller 1212 .

[0081] The second wireless communication module 1211 is electrically connected to the second controller 1212 and is in communication connection with the microphone transmitting board 111. The second wireless communication module 1211 can send data to the microphone transmitting board 111 or receive data sent by the microphone transmitting board 111 under the control of the second controller 1212. In some embodiments, the second wireless communication module 1211 can use any suitable type of wireless communication technology, such as Bluetooth, Wi-Fi, etc.

[0082] The second controller 1212 is electrically connected to the audio main control board 122, and is used to control the second wireless communication module 1211 to receive the first light control signal or audio data sent by the microphone transmitting board 111 and forward the first light control signal or audio data to the audio main control board 122, so that the audio main control board 122 can realize light control according to the first light control signal or realize audio playback control according to the audio data.

[0083] It is understandable that if Figure 3 As shown, the second wireless communication module 1211 is connected to the first wireless communication module 1113, so the second controller 1212 and the first controller 11123 can communicate and interact with each other through the second wireless communication module 1211 and the first wireless communication module 1113. When the second controller 1212 interacts with the first controller 11123, the second controller 1212 can send various data to the first controller 11123 or receive various data sent by the first controller 11123 through the second wireless communication module 1211.

[0084] Any suitable type of communication protocol may be used to transmit various data between the second controller 1212 and the first controller 11123. The communication protocol may be an unreliable communication protocol or a reliable communication protocol.

[0085] An unreliable communication protocol refers to a communication protocol used to implement unreliable data transmission between the second controller 1212 and the first controller 11123. For example, unreliable communication protocols include protocols such as UDP (User Datagram Protocol). UDP is relatively simple and easy to implement. It has no confirmation mechanism. Once a data packet is sent, it is impossible to know whether the other party has received it. Although it can achieve fast data transmission, the transmission reliability is poor.

[0086] A reliable communication protocol refers to a communication protocol used to achieve reliable data transmission between the second controller 1212 and the first controller 11123. For example, reliable communication protocols include protocols such as TCP (Transmission Control Protocol). TCP is a connection-oriented, reliable, byte stream-based transport layer communication protocol. Simply put, TCP is UDP with a confirmation mechanism. Each data packet sent requires confirmation. If a data packet is lost, no confirmation will be received, and the sender must resend the data packet. The TCP protocol establishes a three-conversation confirmation mechanism based on UDP, that is, before officially sending and receiving data, a reliable connection must be established with the other party, so the reliability of transmission can be guaranteed, but data transmission is slow.

[0087] In some embodiments, an unreliable communication protocol may be used when audio data is transmitted between the second controller 1212 and the first controller 11123 , and a reliable communication protocol may be used when message variables other than audio data are transmitted between the second controller 1212 and the first controller 11123 .

[0088] In some embodiments, the second controller 1212 includes a first UART (Universal Asynchronous Receiver and Transmitter) interface and a first DAC (Digital to Analog Converter) interface.

[0089] The first UART interface is used to connect the second controller 1212 and the audio main control board 122. It is a universal serial data bus used for asynchronous communication. The universal serial data bus can be a bidirectional communication bus, which converts the data to be transmitted between serial communication and parallel communication.

[0090] The first DAC interface is used to connect the second controller 1212 and the audio main control board 122. The second controller 1212 can perform digital-to-analog conversion on the audio data received from the microphone transmitting board 111, and output the audio signal obtained after the digital-to-analog conversion to the audio main control board 122 through the first DAC interface.

[0091] In some embodiments, Figure 3 As shown, the audio main control board 122 includes a third wireless communication module 1221 and a third controller 1222 .

[0092] The third wireless communication module 1221 is connected to the terminal device 20 for receiving digital audio data sent by the terminal device 20. The digital audio data is the audio data used by the speaker 12 for real-time playback of music such as accompaniment. In some embodiments, the third wireless communication module 1221 can use any suitable type of wireless communication technology, such as Bluetooth, Wi-Fi, etc.

[0093] The third controller 1222 is electrically connected to the microphone receiver 121 , the second light emitting module 123 and the third wireless communication module 1221 respectively.

[0094] On the one hand, the third controller 1222 can receive the first light control signal forwarded by the microphone receiver 121 and control the second light emitting module 123 to emit light according to the first light control signal. At this time, the microphone transmitting board 111 also controls the first light emitting module 112 to emit light according to the first light control signal, and the first light control signal comes from the human voice, so the microphone 11 and the speaker 12 can emit light in conjunction with the human voice.

[0095] On the other hand, the third controller 1222 can receive the digital audio data sent by the terminal device 20 through the third wireless communication module 1221 and process the digital audio data to obtain a second light control signal, and send the second light control signal to the microphone transmitting board 111 through the microphone receiver 121, so that the microphone transmitting board 111 controls the first light-emitting module 112 to emit light according to the second light control signal. At this time, the third controller 1222 also controls the second light-emitting module 123 to emit light according to the second light control signal, and the second light control signal comes from the accompaniment, so the microphone 11 and the speaker 12 can emit light in conjunction with the accompaniment.

[0096] In some embodiments, the third controller 1222 includes a second UART interface, a second AUX interface, a first MUTE interface, a second DAC interface, and a second SPI interface.

[0097] The second UART interface is electrically connected to the first UART interface, thereby achieving communication and interaction between the third controller 1222 and the second controller 1212 .

[0098] The second AUX interface is electrically connected to the first DAC interface. The third controller 1222 can receive the audio signal output by the third controller 1222 through the first DAC interface through the second AUX interface. Since the audio signal is an analog signal, the third controller 1222 needs to convert the audio signal into a digital signal before further signal processing.

[0099] The first MUTE interface is electrically connected to the power amplifier 1223. The first MUTE interface is a mute control interface. The third controller 1222 can output a control signal to the power amplifier 1223 through the first MUTE interface, so that the power amplifier 1223 responds to the control signal and turns off the output to achieve a mute effect. In some embodiments, the control signal can be a signal of any level type, such as a high level signal or a low level signal.

[0100] The second DAC interface is electrically connected to the power amplifier 1223. The third controller 1222 can perform digital-to-analog conversion on the audio data received from the second controller 1212 or the terminal device 20, and output the audio signal obtained after the digital-to-analog conversion to the power amplifier 1223 through the second DAC interface.

[0101] The second SPI interface is used to connect the third controller 1222 and the second light emitting module 123. The second SPI interface is a synchronous peripheral interface, which enables the third controller 1222 and the second light emitting module 123 to communicate in serial mode to exchange information, thereby driving the second light emitting module 123 to emit light.

[0102] The power amplifier 1223 is used to receive the analog audio signal sent by the third controller 1222 and amplify the power of the analog audio signal for subsequent audio playback. In some embodiments, the power amplifier 1223 is a power integrated amplifier, wherein the power integrated amplifier can be constructed in any form, for example, the power integrated amplifier is an SC2306 chip, which is a chip with a built-in asynchronous automatic boost module that provides ample power output for the audio, and the maximum boost value is optional between the four voltage values ​​of 5.7V, 6.6V, 7.2V and 7.5V. When the input signal is small, the boost circuit does not work, and the four voltage values ​​are optional. When the input signal is small, the boost circuit does not work, and the class D is directly powered by the power supply; when the input signal becomes larger, the boost module is automatically turned on to boost the voltage to the intermediate level to power the class D; when the input signal becomes larger, the boost circuit continues to boost the voltage to the maximum voltage set by the user to power the class; when the input signal becomes larger, the boost circuit continues to boost the voltage to the maximum voltage set by the user to power the class D, which can improve the system efficiency and extend battery life.

[0103] In some embodiments, Figure 3 As shown, the audio system 12 also includes a speaker 124 .

[0104] The speaker 124 is electrically connected to the power amplifier, and is used to play audio according to the analog audio signal after power amplification by the power amplifier 1223 .

[0105] The speaker 124 is a transducer device that converts an electrical signal into an acoustic signal. The speaker 124 can be any suitable type of speaker, such as an electric speaker, a magnetic speaker, an ion speaker, and the like.

[0106] In some embodiments, the second light emitting module 123 is a colorful light panel.

[0107] See also Figure 5 The second light emitting module 123 includes a second light driving board 1231 , a second annular colorful light strip 1232 and a second rectangular colorful light strip 1233 .

[0108] The second light driving board 1231 is electrically connected to the audio main control board 122, and is used to generate a second light driving signal in response to the second light control signal. The second light driving signal can be a driving voltage / driving current.
