Description
Technical Field
[0001] The present application belongs to the field of lighting control technology, and relates to an acousto-optic linkage device, and in particular to an acousto-optic linkage device, equipment, and system. Background Art
[0002] In recent years, with the rapid development of smart homes, home theater systems, and background music systems, lighting and sound integration technology has gradually become a focus of market attention. This technology synchronizes lighting effects with music or sound, providing users with a more immersive and interactive visual and auditory experience. Currently, a variety of lighting and sound integration products are available on the market, including sound pickup lamps, stage lighting systems, and home entertainment lighting systems.
[0003] Sound-sensing lamps are among the most popular products that integrate lighting and sound. These products typically connect to a user's smartphone or other device via Bluetooth or Wi-Fi, allowing users to control the lamp's color, brightness, color temperature, and even sync with music through a mobile app. These lamps incorporate built-in microphones that capture ambient sound and adjust lighting effects in real time based on audio changes, such as those from sounds or music played on external devices. Some application terminals also offer a variety of preset or customizable lighting modes to meet user needs in diverse scenarios.
[0004] Stage lighting systems are primarily used in large-scale performances, concerts, and plays. These systems typically consist of multiple lighting devices, centrally controlled via protocols such as DMX512. Stage lighting engineers can design lighting plans based on the music and performance content, controlling the color, brightness, position, and dynamic effects of the lights in real time to enhance the visual impact of the performance. Representative products of this type include Martin Professional and Chauvet Professional.
[0005] Home entertainment lighting systems are primarily used in settings like home theaters and family gatherings. These systems typically include multiple lighting devices and a centralized controller, allowing users to control lighting effects via a remote control or mobile app. Compared to sound-sensing lighting fixtures, home entertainment lighting systems offer more complex control and richer functionality, enabling multi-device collaboration. Typical products include Nanoleaf, Govee, Philips Hue, and LIFX.
[0006] However, the products with light and sound linkage in the prior art have the following defects:
[0007] Sound-collecting lamps cannot filter out ambient noise and accurately present the audio information of the music being played. In addition, the lighting effects between lamps are unrelated and cannot meet the user's needs for sound and light synchronization.
[0008] The stage lighting system is more of a pre-programmed scene lighting effect, which cannot be switched freely to any music, and it is difficult to apply this system to scenes such as home use and outdoor camping;
[0009] Although the home entertainment lighting system can meet the needs of some users for home scenes, it does not solve the dependence between the lighting system and smart speakers.
[0010] In summary, the lighting system in the existing technology can only be used in specific scenarios and cannot meet the user's needs for sound and light synchronization in different scenarios. Summary of the Invention

[0058] The following describes the embodiments of the present application through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.
[0059] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.
[0060] The following embodiments of the present application provide a sound-light linkage device, equipment and system, which solves the problem that the lighting system in the prior art can only be used in specific scenarios and cannot meet the user's needs for sound-light synchronization in different scenarios and users.
[0061] The principles and implementation methods of an acousto-optic linkage device, equipment, and system of this embodiment will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can understand an acousto-optic linkage device, equipment, and system of this embodiment without creative work.
[0062] like Figure 1 As shown, this embodiment provides an acousto-optic linkage device, and the acousto-optic linkage device 1 includes: a digital signal processor 11 and a microprocessor 12.
[0063] A digital signal processor 11 receives a first audio signal from an audio playback source and outputs a second audio signal related to the first audio signal.
[0064] The microprocessor 12 has an input end communicatively connected to an output end of the digital signal processor, and an output end communicatively connected to at least one light-emitting device; an analog input pin of the microprocessor receives the second audio signal, and a control pin of the microprocessor outputs a control signal related to the second audio signal to the light-emitting device.
[0065] Specifically, the digital signal processor in this application collects the first audio signal emitted by the audio playback source and outputs a second audio signal related to the first audio signal. The microprocessor receives the second audio signal and outputs a control signal related to the second audio signal to control at least one of the light-emitting devices, thereby achieving the sound and light rhythmic effect of at least one light-emitting device. At the same time, the sound and light linkage device in this application can be used in various scenarios (indoors and outdoors), not limited to a specific scenario, and can meet the user's usage needs in different scenarios. It is flexible and convenient. By analyzing
[0066] In one implementation, the digital signal processor 11 is a DSP. A DSP (Digital Signal Processor) is a microprocessor specifically designed for real-time digital signal processing. It receives analog signals, converts them into digital signals, then performs various analyses on the digital signals, ultimately converting the analyzed digital signals back into analog signals for practical use. DSP chips feature a Harvard architecture, hardware multipliers, and pipeline operations, resulting in exceptional processing speed and efficiency. This has led to their widespread application in numerous fields, such as communications, automatic control, and image processing.
[0067] In one implementation, the microprocessor 12 is an MCU (Microcontroller Unit, or single-chip microcomputer). An MCU is a microcomputer system that integrates a central processing unit (CPU), memory (RAM and ROM), and input / output (I / O) interfaces on a single chip. The MCU's highly integrated design not only saves space but also provides powerful control and computing capabilities.
[0068] Figure 2 Shown is a structural diagram of the sound and light linkage device according to another embodiment of the present application. Figure 2 As shown, the sound-light linkage device includes a DSP digital signal processor and an MCU microprocessor. The DSP digital signal processor inputs a first audio signal emitted by an audio playback source and outputs a second audio signal related to the first audio signal. The MCU microprocessor's input terminal is communicatively connected to the DSP digital signal processor's output terminal, and the output terminal is communicatively connected to at least one light-emitting device (lamp) via a wired or wireless method. An analog input pin of the MCU microprocessor receives the second audio signal, and a control pin of the MCU microprocessor outputs a control signal related to the second audio signal to the lamp. Simultaneously, the second audio signal output by the DSP digital signal processor is looped out to audio equipment and other devices.
[0069] Loop-out is a data acquisition card feature that allows collected data to be transmitted to an external device in real time via an output port. This functionality allows the card to send collected data to an external device, such as a display or audio device, for real-time monitoring and analysis. This feature is particularly useful for applications requiring real-time monitoring and processing, such as video surveillance and audio processing.
[0070] It should be noted that the audio playback source is a mobile phone, computer, tablet, background music player, home theater player, etc. This application is not limited to this.
[0071] This application collects and analyzes the first audio signal emitted by the audio playback source. The digital signal processor collects the first audio signal emitted by the audio playback source, analyzes the first audio signal, and outputs a second audio signal related to the first audio signal to the analog input pin of the microprocessor. Then, the control signal related to the second audio signal is output to the light-emitting device through the control pin of the microprocessor. It can remove external environmental noise, and realize the sound and light rhythm of at least one light-emitting device by analyzing music data and converting the audio information into light effects through the algorithm. This application is implemented using the existing sound and light linkage technology, and no technical improvements are made in this part. The innovative design of this application is the structural design of the sound and light linkage device, and its combined communication method with the audio playback source, light-emitting device and / or audio equipment.
[0072] In one embodiment of the present application, the input end of the digital signal processor is communicatively connected to the output end of the audio playback source via an audio data line.
[0073] In one embodiment of the present application, the digital signal processor is communicatively connected to the audio playback source via a Bluetooth wireless communication link.
[0074] This application does not rely on wired connections to obtain sound data. It can obtain audio information through a physical hardware interface or by wirelessly receiving audio information from an audio playback source. By analyzing music data, multiple lighting devices can follow the rhythm of the music, achieving the sound and light rhythmic effect of at least one lighting device.
[0075] In one embodiment of the present application, the microprocessor is communicatively connected to the light-emitting device via a wired communication link.
[0076] Specifically, in this embodiment, the microprocessor controls the light-emitting device via a wired communication link.
[0077] In one embodiment of the present application, the microprocessor is communicatively connected to the light emitting device via a wireless communication link.
[0078] Specifically, in this embodiment, the microprocessor controls the light-emitting device via a wireless communication link.
[0079] It should be noted that the present application does not rely on wired connections to control light-emitting devices. It can control light-emitting devices through physical hardware interfaces or wirelessly. By parsing music data, multiple lighting devices can follow the rhythm of the music, achieving the sound and light rhythmic effect of at least one light-emitting device.
[0080] In one embodiment of the present application, the wireless communication link includes a Bluetooth, WIFI, Zigbee or / and Thread wireless protocol communication link.
[0081] Specifically, in this embodiment, the microprocessor controls the light-emitting device via a wireless connection such as Bluetooth, WIFI, Zigbee, or / and Thread wireless protocol communication link, so as to transmit a control signal related to the second audio signal to the light-emitting device.
[0082] like Figure 3 As shown, an embodiment of the present application provides an acousto-optic linkage device, and the acousto-optic linkage device 2 includes the acousto-optic linkage device 1 as described above.
[0083] In one embodiment of the present application, the sound and light linkage device is a speaker.
[0084] In this embodiment, the sound-light linkage device 1 is embedded in an audio device. The sound-light linkage device 1 receives a first audio signal from an audio playback source via a digital signal processor 11 and outputs a second audio signal related to the first audio signal. Because the sound-light linkage device 1 is embedded in the audio device, when music is transmitted to the audio device, the audio device can remotely control surrounding lighting devices through the microprocessor 12 in the sound-light linkage device 1. This control can be done wirelessly or wired, allowing the lighting devices, such as lamps, to follow the music emitted by the audio device to generate relevant rhythmic movements.
[0085] Regarding the dependency between the lighting system and the smart speakers, the existing home entertainment lighting system can only meet the needs of some users for home scenes, and cannot solve the dependency between the lighting system and the smart speakers. For this problem, there are currently two solutions in the existing technology: 1. Connect a controller between the playback source and the speakers via a wired method. The controller collects audio data via a wired method and analyzes the data to control the surrounding lighting equipment. This method requires that the playback source and the speakers need to be connected via a wired method, which cannot meet the needs of users who currently use mobile devices to wirelessly connect to speakers to play music; 2. Use a computer as a music playback source and connect to the speakers wirelessly via Bluetooth or WiFi to play music. Usually, it is necessary to develop corresponding software on the computer side to parse the audio output data in real time and control the surrounding lighting effects in some way. This method often controls a lamp via a USB wired method, or requires cooperation with a home hub gateway to control the lighting equipment in the home.
[0086] Therefore, in order to solve the dependency problem between the above-mentioned lighting system and the smart speaker, the embodiment of the present application provides a variety of sound and light linkage systems. There are three interaction modes between the sound and light linkage device and the audio equipment: embedded, front and rear. There is no fixed user interaction mode, which can solve the dependency problem between the sound and light linkage device and the audio equipment, thereby achieving technical effects for use in multiple scenarios (indoor and outdoor). The interaction method is flexible and convenient, giving users a better user experience.
[0087] like Figure 4 As shown, an embodiment of the present application provides a sound and light linkage system, and the sound and light linkage system 3 includes: an audio playback source 31, a sound and light linkage device 32 and a light-emitting device 33.
[0088] An audio playback source 31 outputs a first audio signal;
[0089] The sound and light linkage device 32 is communicatively connected to the audio playback source via a first communication link, and includes the sound and light linkage device 1 as described above;
[0090] The light emitting device 33 is communicatively connected to the acousto-optic linkage device via a second communication link.
[0091] In this embodiment, the sound-light linkage device 32 is an audio device with the sound-light linkage device 1 embedded therein. The sound-light linkage device 32 receives a first audio signal emitted by an audio playback source through the digital signal processor 11 in the sound-light linkage device 1, and outputs a second audio signal related to the first audio signal. Because the sound-light linkage device 1 is embedded in the audio device, when music is transmitted to the audio device, the audio device can remotely control the surrounding light-emitting devices through the microprocessor 12 in the sound-light linkage device 1, and control the surrounding light-emitting devices, such as lamps, wirelessly or wired, so that the lamps can perform related rhythms according to the music emitted by the audio device.
[0092] Figure 5 The diagram shows a schematic diagram of an application scenario of the sound and light linkage system described in an embodiment of the present application. Figure 5 As shown, the sound and light linkage device 1 is embedded in the audio equipment, the music playback source and the audio equipment are connected via an audio data cable or Bluetooth wireless communication, and the sound and light linkage device 1 and several lamps are connected via wired communication or wireless control protocols such as Bluetooth, WIFI, Zigbee or / and Thread.
[0093] The audio device receives the audio signal emitted by the music playback source. Since the sound and light linkage device 1 is embedded in the audio device, when the music is transmitted to the audio device, the audio device can remotely control several surrounding lamps through the sound and light linkage device 1, so that the lamps can perform related sound and light rhythms according to the music emitted by the audio device.
[0094] like Figure 6 As shown, an embodiment of the present application provides a sound and light linkage system, and the sound and light linkage system 4 includes: an audio playback source 41, the sound and light linkage device 1 as described above, a light emitting device 42 and an audio device 43.
[0095] An audio playback source 41 outputs a first audio signal;
[0096] The sound and light linkage device 1 as described above is communicatively connected to the audio playback source via a first communication link;
[0097] a light emitting device 42, communicatively connected to the acousto-optic linkage device via a second communication link;
[0098] The audio device 43 is communicatively connected to the sound and light linkage device via a third link.
[0099] In this embodiment, in the sound and light linkage system 4, the sound and light linkage device 1 is placed in front of the audio device 43, and the sound and light linkage device 1 is directly plugged into the audio device 43 in a wired or wireless manner. The sound and light linkage device 1 receives the first audio signal emitted by the audio playback source 41 through the digital signal processor 11, and outputs a second audio signal related to the first audio signal after collection and analysis. On the one hand, the sound and light linkage device 1 transmits the second audio signal to the audio device through the digital signal processor 11. On the other hand, the sound and light linkage device 1 remotely controls the surrounding light-emitting devices through the microprocessor 12, and controls the surrounding light-emitting devices, such as lamps, in a wireless or wired manner, so that the lamps can perform related sound and light rhythms according to the music emitted by the audio device.
[0100] Figure 7 The diagram shows a schematic diagram of an application scenario of the sound and light linkage system described in an embodiment of the present application. Figure 7 As shown, the music playback source and the sound and light linkage device 1 are connected via an audio data cable or Bluetooth wireless communication, the sound and light linkage device 1 and the audio equipment are connected via a 3.5 mm audio data cable or wireless communication, and the sound and light linkage device 1 and several lamps are connected via wired communication or wireless control protocols such as Bluetooth, WIFI, Zigbee or / and Thread.
[0101] The sound and light linkage device 1 collects and analyzes the audio signal emitted by the music playback source. On the one hand, the sound and light linkage device 1 transmits the analyzed audio signal to the audio equipment. On the other hand, the sound and light linkage device 1 remotely controls several surrounding lamps, allowing the lamps to perform related sound and light rhythms according to the music emitted by the audio equipment.
[0102] like Figure 8 As shown, an embodiment of the present application provides a sound and light linkage system, and the sound and light linkage system 5 includes: an audio playback source 51, an audio device 52, the sound and light linkage device 1 as described above, and a light-emitting device 53.
[0103] An audio playback source 51 outputs a first audio signal;
[0104] The audio device 52 is communicatively connected to the audio playback source via a fourth communication link;
[0105] The sound and light linkage device 1 as described above is communicatively connected to the audio device via a fifth communication link;
[0106] The light emitting device 53 is communicatively connected to the acousto-optic linkage device via a second communication link.
[0107] In this embodiment, in the sound-light linkage system 5, the sound-light linkage device 1 is placed after the audio device 43, and the sound-light linkage device 1 is directly plugged into the audio device 43 in a wired or wireless manner. The audio device 52 receives the first audio signal emitted by the audio playback source 51, and the sound-light linkage device 1 can directly derive the corresponding audio information from the audio device 52 to collect and analyze it. At the same time, the sound-light linkage device 1 remotely controls the surrounding light-emitting devices through the microprocessor 12, and controls the surrounding light-emitting devices, such as lamps, in a wireless or wired manner, so that the lamps can perform related sound and light rhythms according to the music emitted by the audio device. In the process of the sound-light linkage device 1 deriving the corresponding audio information from the audio device 52 and collecting and analyzing it, it will not affect the transmission of the first audio signal from the audio playback source 51 to the audio device 52.
[0108] Figure 9 The diagram shows a schematic diagram of an application scenario of the sound and light linkage system described in an embodiment of the present application. Figure 9 As shown, the music playback source and the audio device are connected via an audio data cable or Bluetooth wireless communication, the sound and light linkage device 1 and the audio device are connected via a 3.5 mm audio data cable or wireless communication, and the sound and light linkage device 1 and several lamps are connected via wired communication or wireless control protocols such as Bluetooth, WIFI, Zigbee or / and Thread.
[0109] The audio device receives the audio signal emitted by the music playback source, and the sound and light linkage device 1 can directly export the corresponding audio information from the audio device 52 to collect and analyze it. At the same time, the sound and light linkage device 1 remotely controls several surrounding lamps through wireless or wired means, so that the lamps can perform related sound and light rhythms according to the music emitted by the audio device.
[0110] It should be noted that, in the process of the sound-light linkage device 1 deriving the corresponding audio information from the audio device and collecting and analyzing the audio information, the transmission of the audio signal from the music playback source to the audio device will not be affected.
[0111] In summary, the acousto-optic linkage device, equipment, and system described in this application have the following beneficial effects:
