[0048] This invention proposes a smart speaker.

[0049] Reference Figures 1 to 5 In one embodiment of the present invention, the smart speaker includes:

[0050] The smart speaker includes:

[0051] Speaker housing 100, wherein the speaker housing 100 is provided with a mounting port;

[0052] The sound-generating component 10 is installed in the speaker housing 100;

[0053] Light guide plate 20, which covers the mounting port;

[0054] A dimming component 30, wherein the light emission direction of the dimming component 30 corresponds to that of the light guide plate 20;

[0055] An electronic control component 40 is electrically connected to the dimming component 30. The electronic control component 40 is used to control the operation of the sound-generating component 10 and the dimming component 30. When the electronic control component 40 controls the dimming component 30 to work synchronously with the sound-generating component 10, it controls the dimming component 30 to dynamically adjust the light emission parameters of the light beam directed toward the light guide plate 20 according to the received audio signal.

[0056] In this embodiment, the speaker housing 100 can be cylindrical, square, prismatic, etc. The speaker housing 100 has an accommodating space and at least one mounting port for installation. It may also have a data interface, a charging interface, etc. The sound-generating assembly 10 has a front cavity and a rear cavity. The front cavity faces the speaker outlet of the speaker housing 100, and the rear cavity of the sound-generating assembly 10 is sealed within the speaker housing 100. The electronic control assembly 40 may include an electronic control board and a main controller 42, a codec, an audio processor, a power amplifier, a power supply circuit, etc., mounted on the electronic control board. The power supply circuit supplies power to the various functional circuit modules on the electronic control board. The codec can process the input digital or analog audio signals and output the results. The codec can perform A / D and D / A conversions on the audio signals. An A / D converter (A / D converter) encodes analog signals audible to the human ear into digital signals audible to a computer; a D / A converter (D / A converter) decodes the processed digital signals into analog signals audible to the human ear. The codec can integrate processing chips with both of these functions. In this embodiment, the audio processor sends the processed digital audio signal to the codec, which then encodes the audio signal and outputs it to the other device via a communication module. A power amplifier is positioned between the sound-generating component 10 and the codec, amplifying the audio signal output by the codec before outputting it to the sound-generating component 10. In other embodiments, the codec can also convert the digital audio signal into an analog audio signal and send it to the power amplifier. The power amplifier then amplifies and filters the input analog audio signal before outputting it to the sound-generating component 10, thus achieving audio playback.

[0057] The light guide plate 20 covers a relevant area of ​​the speaker housing 100, and the projection angle of the dimming component 30 can be adjusted as needed. The dimming component 30 includes RGB-LED lights and a driver chip for driving the RGB-LED lights, etc. By setting up RGB-LEDs, the smart speaker can display changes in LED brightness and color during the power-on process, forming an interaction with the operator. The number of LED driver chips and RGB-LED lights can be expanded according to the needs of the product logo projection, and then controlled by the electronic control component 40 via I2C. Subsequently, in conjunction with the design of the light guide plate 20, the logo pattern displayed on the RGB LEDs of the smart speaker can be projected onto an adjacent wall, not only for changes in LED color and brightness, but also for the RGB LEDs to interact with the user and the music being played.

[0058] This invention uses an electronic control component 40 to control the operation of the sound-generating component 10 and the dimming component 30. When controlling the dimming component 30 and the sound-generating component 10 to operate synchronously, the invention dynamically adjusts the light emission parameters of the beam from the light guide plate 20 based on the received audio signal, so that the displayed content and the played music can change synchronously, achieving a combination of audiovisual elements. This invention can project the display onto a corresponding area, achieving rhythmic display of the projection area, linking sound and display, and enhancing the user experience.

[0059] Reference Figures 1 to 5 In one embodiment, the light emission parameters include at least color, brightness, and light emission duration;

[0060] The electronic control component 40 is specifically used to control the dimming component 30 to dynamically adjust any one or more combinations of the light emission parameters directed at the source, based on the strength and / or frequency of the audio signal.

[0061] When the electronic control component 40 controls the dimming component 30 to dynamically adjust the light emission parameters of the light beam directed towards the light guide plate 20 according to the strength of the audio signal, specifically:

[0062] The dimming component 30 is controlled to emit a color and / or brightness that follows the intensity of the audio signal.

[0063] When the electronic control component 40 controls the dimming component 30 to dynamically adjust the light emission parameters of the light beam directed towards the light guide plate 20 according to the frequency of the audio signal, specifically:

[0064] The display time of the dimming component 30 is controlled to follow the frequency change of the audio signal.

[0065] In this embodiment, adjusting the brightness of the dimming component 30 according to changes in the intensity of the audio signal includes: determining the intensity of the audio signal volume, with different volume intensities corresponding to different brightness levels of the dimming component 30. Specifically, a correspondence is established between the volume intensity and the brightness of the dimming component 30, with different volume intensities corresponding to different brightness levels of the dimming component 30. For example, a brighter brightness can be used to synchronize the audio signal when the volume is high, and a darker brightness can be used to synchronize the audio signal when the volume is low. When the current audio signal volume intensity is obtained, the adjustment brightness and color of the dimming component 30 can be determined according to the correspondence between the volume intensity and the brightness of the dimming component 30, and then the brightness of the dimming component 30 is adjusted. Adjusting the emission color of the dimming component 30 according to changes in the intensity of the audio signal includes: determining the intensity of the audio signal volume, with different volume intensities corresponding to different emission colors of the dimming component 30. Specifically, a correspondence is established between the emission color of the volume and the brightness of the dimming component 30, with different volume intensities corresponding to different emission colors of the dimming component 30. For example, a more vibrant color can be used to synchronize the audio signal when the volume is high, while a more muted color can be used to synchronize the audio signal when the volume is high. Once the current audio signal volume intensity is obtained, the adjustment brightness of the dimming component 30 can be determined based on the correspondence between the volume intensity and the brightness of the dimming component 30, and then the brightness of the dimming component 30 is adjusted.

[0066] The display time follows the frequency change of the audio signal, including determining the frequency of the audio signal. Different frequencies of the audio signal correspond to different display times of the dimming component 30. Specifically, a correspondence is established between the frequency of the audio signal and the display time of the dimming component 30. Different frequencies of the audio signal correspond to different display times of the dimming component 30. For example, a longer display time can be used to synchronize audio signals with lower frequencies, and a shorter display time can be used to synchronize audio signals with higher frequencies. When the frequency of the current audio signal is obtained, the display time of the dimming component 30 can be determined according to the correspondence between the frequency of the audio signal and the display time of the dimming component 30, and then the display time of the dimming component 30 can be adjusted.

[0067] The product logo can be projected onto a nearby wall, and the color and brightness of the projected logo area can be adjusted according to the dynamics of the music playing. For example, when the volume of the music increases, the brightness of the corresponding logo area increases, and when the volume decreases, the brightness of the corresponding logo area decreases. Simultaneously, the corresponding color can be dynamically adjusted. Furthermore, when the frequency of the music changes, the display time of the corresponding logo area changes accordingly.

[0068] Reference Figures 1 to 5In one embodiment, the electronic control component 40 is used to receive video signals output by an external terminal and control the dimming component 30 to dynamically adjust the light emission parameters of the light beam directed toward the light guide plate 20 according to the video signals, so as to follow the changes in the video signals output by the external terminal.

[0069] In this embodiment, when the smart speaker is connected to an external terminal such as a television, the electronic control component 40 can receive video data sent by the external terminal via wired or wireless means. Based on the received video data, it determines the brightness and / or color information of the video frame at the edge of the external terminal and controls the brightness and / or color changes of the dimming component 30 to follow the brightness and / or color information of the video frame at the edge of the external terminal. This adjusts the brightness and color of the dimming component 30, creating an extended display with the video played on the television. This extends the video's atmosphere from the television screen to the surrounding space, making the brightness or color effect of the entire space correspond to the content being played. This allows the light guide plate 20 to illuminate the ceiling, floor, or side walls next to the television as needed, creating a better viewing atmosphere. In some embodiments, the brightness of the dimming component 30 can also be adjusted according to the environment of the external terminal, so that the brightness of the dimming component 30 can adapt to the viewing atmosphere. For example, at night, the color and brightness of the surrounding space can be adjusted to a warm tone, while during the day, it can be adjusted to a more saturated tone.

[0070] Reference Figures 1 to 5 In one embodiment, the electronic control component 40 includes:

[0071] The signal access circuit 41 is used to communicate with an external terminal to receive audio signals output by the external terminal.

[0072] The main controller 42 is electrically connected to the signal access circuit 41, the dimming component 30 and the sound-generating component 10 respectively. The main controller 42 is used to control the dimming component 30 and the sound-generating component 10 to work according to the audio signal accessed by the signal access circuit 41.

[0073] In this embodiment, the signal access circuit 41 can be implemented using a wired communication circuit or a wireless communication circuit. The wired communication circuit can be equipped with a 3.5mm external audio input interface, which can input external wired audio signals to the main controller 42. The wired communication circuit can also be equipped with a Type-C, Micro USB, or round power interface as a charging or direct power supply port for the product. It can also connect to an external terminal via the Type-C, Micro USB, or round power interface, and the external terminal can send audio signals to the main controller 42 via the Type-C, Micro USB, or round power interface. The wireless communication circuit can include wireless modules such as WIFI modules and Bluetooth modules. Through the wireless module connection, the main controller 42 can also obtain the video signal played by the connected terminal (such as a mobile phone, car TV, or television), and can also obtain the edge color data displayed in the video. Then, the MCU can refresh the RGB display state through I2C to achieve the effect of display extension (the same color as the inner edge display of the TV screen). The main controller 42 can be the central processing unit of the smart speaker or a main controller 42 specifically used for LED adjustment. A memory can also be set up in the smart speaker to store programs that implement the above methods, as well as the aforementioned control commands—a voice database. When the main controller 42 is the control center (CPU) of the smart speaker, it can connect various parts of the smart speaker using various interfaces and lines. By running or executing software programs and / or modules stored in the memory, and by calling data stored in the memory, it can perform various functions of the smart speaker and process data, thereby responding to control commands received by the smart speaker. The main controller 42 can also be a microcontroller, a general-purpose main controller 42, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices.

[0074] Reference Figures 1 to 5 In one embodiment, the main controller 42 has a video working mode, an audio working mode, and an audio-visual working mode;

[0075] The electronic control component 40 also includes:

[0076] The user input circuit 43 is electrically connected to the main controller 42. When the user input circuit 43 is triggered by the user, it outputs the corresponding control command.

[0077] When the main controller 42 determines that the control instruction is a mode selection control instruction, it operates in one of the video working mode, audio working mode, and audio-visual working mode.

[0078] In this embodiment, when working in the video working mode, the main controller 42 controls the dimming component 30 to dynamically adjust the light emission parameters of the light beam directed toward the light guide plate 20 according to the video signal received by the electronic control component from the external terminal, so as to follow the changes in the video signal output by the external terminal.

[0079] When operating in the audio working mode, the main controller 42 controls the sound-generating component 10 to work and controls the dimming component 30 to not work.

[0080] When operating in the audio-visual working mode, the main controller 42 controls the dimming component 30 to work synchronously with the sound-generating component 10, and controls the dimming component 30 to dynamically adjust the light emission parameters of the light beam directed towards the light guide plate 20 according to the received audio signal.

[0081] The smart speaker can adapt to different operating modes of the dimming component 30 depending on the usage state. For example, in audio-visual working mode, the smart speaker can connect to external terminals such as mobile phones and smart bracelets to play audio signals received from external terminals. At the same time, the dimming component 30 changes with the changes in the audio signal. That is, the electronic control component 40 controls the dimming component 30 to dynamically adjust the light emission color and / or brightness according to the strength and / or frequency of the audio signal, and controls the display time of the dimming component 30 to follow the frequency changes of the audio signal, so that the logo pattern displayed on the RGB LED of the smart speaker is projected onto the adjacent wall, and the color, strength and time of the projected display pattern can all rhythmically change with the melody of the music being played. In video mode, the smart speaker can connect to external terminals such as TVs or set-top boxes via wired or wireless connections to receive video signals output from these terminals. In this mode, the electronic control component 40 can determine the brightness and / or color information of the video frames at the edge of the external terminal based on the received video data, and control the brightness and color changes of the dimming component 30 to follow the brightness and / or color information of the video frames at the edge of the external terminal. This adjusts the brightness and color of the dimming component 30, creating an extended display with the video played on the TV. In this mode, the smart speaker can either control only the dimming component 30 to work, or receive audio signals output from the TV and simultaneously play audio signals received from the TV. In audio mode, the smart speaker can connect to external terminals such as mobile phones and smart bracelets to play audio signals received from these external terminals. In this case, the dimming module can be disabled, and only the audio signal can be played.

[0082] In some embodiments, in response to a received user-triggered control command, the control of the dimming component 30 is changed, causing at least one of the brightness or color of the dimming component 30 to change. For example, when a user activates voice control via voice input, the smart speaker adjusts the dimming component 30 in response to the voice control command. The smart speaker determines the adjustment parameters of the dimming component 30 based on changes in the input voice parameters, with different adjustment parameters corresponding to different voice parameters. Alternatively, the user can output operation commands to the smart speaker via buttons, operation panels, etc., to adjust the smart speaker's operating mode. Alternatively, the user can also send corresponding control commands to the smart speaker via an external terminal wirelessly connected to the smart speaker to control the dimming component 30, the dimming component, etc., meaning that functions related to the dimming component 30 can be turned on and off, or set to a fixed brightness and color display state, through relevant commands or interactive control.

[0083] Reference Figures 1 to 5 In one embodiment, the light guide plate 20 is rotatably connected to the speaker housing 100, and when the light guide plate 20 rotates to the target position, it forms a corresponding light emission angle;

[0084] And / or, the number of light guide plates 20 is multiple, and the multiple light guide plates 20 are respectively disposed at the mounting ports corresponding to the speaker housing 100.

[0085] In this embodiment, the number of light guide plates 20 can be one or more. When set to one, multiple light guide plates 20 can be installed at different positions on the speaker housing 100 to form different light emission angles. Alternatively, the light guide plates 20 can be rotated by drive components such as motors, gears, and racks to rotatably connect with the speaker housing 100, thereby forming different light emission angles. In practical applications, the light emission angle of the light guide plate 20 can be adjusted to the angle corresponding to the video working mode, audio working mode, or audio-visual working mode, depending on whether the smart speaker is working in video working mode, audio working mode, or audio-visual working mode. For example, when working in video working mode, the light emission angle of the light guide plate 20 can be adjusted to the angle corresponding to the two sides of the TV. When working in audio-visual working mode, the light emission angle of the light guide plate 20 can be adjusted to a certain angle corresponding to the wall, ceiling, or floor. The specific adjustment can be made according to the user's needs and is not limited here.

[0086] To better illustrate the inventive concept of this invention, the working principle of this invention will be explained below in conjunction with the above embodiments:

[0087] See Figure 5In the diagram, A represents the MCU, the control center of the speaker; B is the external power interface, typically Type-C, Micro USB, or a round power interface, used for charging or direct power supply; C is the charger, which controls and manages the speaker's charging current via A; D is the speaker's battery; I is the SPI Flash, which stores pre-set data; J is the memory, specifically DDR4 memory, used to temporarily store MCU operating data or data for interaction with external devices via wireless modules such as WIFI / BT(H); H is the chip for wireless modules such as WIFI or Bluetooth, which connects to and interacts with external WIFI or Bluetooth devices via an antenna; L is the power control button, which controls the power state of the power management IC(K), allowing the MCU(A) to operate in different working modes; synchronous MCU(A) can communicate via SPI or I2C. The control power management (K) IC controls the output voltage of each power supply; M can be used as a 3.5mm external audio input interface; N is the debugging interface, generally used for internal debugging; T is the touch chip, controlled by the touch button (T1) of T1, the number of buttons can be configured as needed, and T2 can be used as the debugging port of the touch chip; U is the digital microphone of the speaker, and an analog microphone can be selected according to the MCU's IO port; W is the audio amplifier, which provides audio power amplification for the speaker, W1 is the tweeter, W2 is the woofer, and can be selected as needed; V is the driver chip for RGB LEDs, and V1 is the RGB LED. M, as a 3.5mm external audio input interface, allows wired audio signals to be input into A (MCU). This smart speaker can also connect wirelessly (via Bluetooth or Wi-Fi) to corresponding terminals (such as mobile phones, car stereos, or TVs). Through the DSP (Digital Signal Processing) integrated within A (MCU), the acquired wired or wireless audio signals are processed by internal algorithms to identify the strength and frequency of the internal audio signal. This allows for I2C refresh of the RGB display state to synchronize with the audio signal. Simultaneously, via Wi-Fi connection, the DSP (Digital Signal Processing) can also acquire video signals played from connected terminals (such as mobile phones, car stereos, or TVs), and simultaneously obtain the edge color data displayed within the video. A (MCU) then refreshes the RGB display state via I2C to achieve the effect of display extension (matching the edge color of the TV screen). Figure 3As shown: A1 is the structural diagram of the smart speaker, where B1 is the arrangement surface of the smart speaker's RGB LEDs, which can be arranged with several related RGB LEDs as needed; where (a1)ABC is set as the logo of the relevant product, and a1 is the relevant area on the light guide plate (film), which covers the area of ​​B1; the angle of RGB projection can be adjusted as needed; c1 is the wall or projection surface of the speaker accessory, b1 is the logo of the product projected onto the wall or projection surface, and d1 is the RGB LED projected onto the corresponding area C1 through the light guide plate (film).

[0088] This invention, through the design of a smart speaker product, projects the product's logo onto a nearby wall. The projected logo area (c1) adjusts its color and brightness according to the dynamics of the music playing. For example, as the music volume increases, the brightness of the corresponding logo area increases; conversely, as the volume decreases, the brightness decreases. Simultaneously, the corresponding color can be dynamically adjusted. Furthermore, as the frequency of the music changes, the display time of the corresponding logo area changes accordingly. This functionality can be turned on and off via commands or interactive controls, or set to a fixed brightness and color display state. Moreover, when the smart speaker is connected to a television, it can create an extended display with the video played on the television, thus providing a better user experience.

[0089] The present invention also proposes a control method for a smart speaker, the smart speaker including a speaker housing and a light guide plate covering the mounting opening of the speaker housing, the smart speaker further including a sound-emitting component and a dimming component, the light emission direction of the dimming component corresponding to the light guide plate;

[0090] Reference Figure 6 The control method for the smart speaker includes the following steps:

[0091] Step S100: Obtain the control command input by the user, and control the sound-generating component and the dimming component to work according to the control command;

[0092] Step S200: When controlling the dimming component and the sound-emitting component to work synchronously, the dimming component is controlled to dynamically adjust the light emission parameters of the light beam directed towards the light guide plate according to the received audio signal.

[0093] In this embodiment, adjusting the brightness of the dimming component according to changes in the intensity of the audio signal includes: determining the intensity of the audio signal volume, with different volume intensities corresponding to different brightness levels of the dimming component. Specifically, a correspondence is established between the volume intensity and the brightness of the dimming component, with different volume intensities corresponding to different brightness levels of the dimming component. For example, a brighter brightness can be used to synchronize the audio signal when the volume is high, and a darker brightness can be used to synchronize the audio signal when the volume is high. Once the current audio signal volume intensity is obtained, the adjustment brightness of the dimming component can be determined based on the correspondence between the volume intensity and the brightness of the dimming component, and then the brightness of the dimming component can be adjusted. Adjusting the color of the dimming component's light emission based on changes in the intensity of the audio signal includes: determining the volume of the audio signal; different volume intensities correspond to different light emission colors from the dimming component; specifically, establishing a correspondence between the volume-based light emission color and the brightness of the dimming component, with different volume intensities corresponding to different light emission colors from the dimming component. For example, a more vibrant color can be used to synchronize the audio signal when the volume is high, while a more muted color can be used to synchronize the audio signal when the volume is high. Once the current audio signal's volume intensity is obtained, the adjustment brightness of the dimming component can be determined based on the correspondence between volume intensity and dimming component brightness, and then the brightness of the dimming component can be adjusted.

[0094] The display time follows the frequency change of the audio signal, including determining the frequency of the audio signal and the corresponding display time of the dimming component for different audio signal frequencies. Specifically, a correspondence is established between the frequency of the audio signal and the display time of the dimming component. Different audio signal frequencies correspond to different display times of the dimming component. For example, a longer display time can be used to synchronize a lower frequency audio signal, and a shorter display time can be used to synchronize a higher frequency audio signal. When the frequency of the current audio signal is obtained, the display time of the dimming component can be determined according to the correspondence between the frequency of the audio signal and the display time of the dimming component, and then the display time of the dimming component can be adjusted.

[0095] The product logo can be projected onto a nearby wall, and the color and brightness of the projected logo area can be adjusted according to the dynamics of the music playing. For example, when the volume of the music increases, the brightness of the corresponding logo area increases, and when the volume decreases, the brightness of the corresponding logo area decreases. Simultaneously, the corresponding color can be dynamically adjusted. Furthermore, when the frequency of the music changes, the display time of the corresponding logo area changes accordingly.

[0096] In this embodiment, when the smart speaker is connected to an external terminal such as a television, the electronic control component can receive video data sent by the external terminal via wired or wireless means. Based on the received video data, it determines the brightness and / or color information of the video frames at the edge of the external terminal and controls the brightness and color changes of the dimming component to follow the brightness and / or color information of the video frames at the edge of the external terminal. This adjusts the brightness and color of the dimming component, creating an extended display with the video played on the television. This extends the video's atmosphere from the television screen to the surrounding space, making the brightness or color effect of the entire space correspond to the content being played. It also allows the light guide plate to illuminate the ceiling, floor, or side walls next to the television as needed, creating a better viewing atmosphere. In some embodiments, the brightness of the adjustment component can also be adjusted according to the environment of the external terminal, so that the brightness of the dimming component can adapt to the viewing atmosphere. For example, at night, the color and brightness of the surrounding space can be adjusted to a warm tone, while during the day, it can be adjusted to a more saturated tone.
