[0069] The technical solutions of the embodiments of this application 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 application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0070] This application provides a method, apparatus, vehicle, and computer-readable storage medium for controlling vehicle sound and light effects.

[0071] The vehicle sound and light effect control method provided in this application embodiment can be applied to a vehicle or a vehicle sound and light effect control device in a vehicle. The vehicle can be a fuel vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc. This disclosure does not make any specific limitations.

[0072] The following is a detailed description in conjunction with the accompanying drawings. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments. Although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown in the drawings.

[0073] Please refer to Figure 1 The first embodiment of the vehicle sound and light effect control method is proposed. The vehicle sound and light effect control method of the first embodiment includes the following steps:

[0074] Step 101: Collect user audio and obtain multimedia audio sent by the central control system;

[0075] In this step, the user can select the desired multimedia audio in the central control system, which will then send the multimedia audio to the vehicle's infotainment system. At the same time, the vehicle will collect the user's audio and send it to the vehicle's infotainment system.

[0076] For example, the vehicle includes an audio acquisition device, a vehicle-mounted infotainment system, and a central control system. The audio acquisition device is an in-vehicle microphone, and the central control system is an in-vehicle tablet. The in-vehicle tablet has a karaoke application installed, with multimedia audio serving as the accompaniment to the song and the user's voice as the audio input. When a user wants to sing karaoke in the vehicle, the user selects the desired song accompaniment in the karaoke application on the in-vehicle tablet. The vehicle-mounted infotainment system can acquire the song accompaniment and play it through the vehicle's speakers. The user sings into the in-vehicle microphone according to the song accompaniment, and the in-vehicle microphone acquires the user's voice and sends it to the vehicle-mounted infotainment system.

[0077] Step 102: Control the light effect system according to the multimedia audio, and output the user audio and the multimedia audio through the sound effect system.

[0078] In this step, after acquiring the user's audio and multimedia audio, the vehicle's infotainment system controls its own lighting system based on the multimedia audio and outputs the user's audio and multimedia audio through the sound system. Specifically, the vehicle includes a lighting system that can implement different lighting effects based on the multimedia audio, and a sound system that can play the user's audio and multimedia audio.

[0079] For example, the lighting system includes a lighting system in the vehicle and a lighting system in the audio acquisition device. The audio acquisition device is an in-vehicle microphone, the multimedia audio is the accompaniment to the song, and the user's audio is the voice. When the user sings karaoke in the car, the lighting system in the vehicle and the lighting system in the audio acquisition device will change the color and brightness according to the accompaniment to the song. At the same time, the sound system will blend the voice and the accompaniment to output the sound, so that the sound and light effects work together to create a stronger karaoke atmosphere, realize the linkage of vision and hearing, and improve the user's karaoke experience in the car.

[0080] Furthermore, the multimedia audio control light effect system includes:

[0081] Step 1021: If the sound effect system is in the first working mode, then control the light effect system in the vehicle according to the multimedia audio control.

[0082] Step 1022: If the sound effect system is in the second working mode, then the light effect system in the audio acquisition device is controlled according to the multimedia audio control.

[0083] Step 1023: If the sound effect system is in the third working mode, then the light effect system in the vehicle and the light effect system in the audio acquisition device are controlled according to the multimedia audio synchronization.

[0084] In steps 1021 to 1023, after the vehicle's infotainment system receives the multimedia audio sent by the central control system, it determines the working mode of the sound effect system. If the sound effect system is in the first working mode, it controls the light effect system in the vehicle according to the multimedia audio. If the sound effect system is in the second working mode, it controls the light effect system in the audio acquisition device according to the multimedia audio. If the sound effect system is in the third working mode, it synchronously controls the light effect system in the vehicle and the light effect system in the audio acquisition device according to the multimedia audio.

[0085] For example, in the first working mode, the sound system is used to play music, and no audio acquisition device is needed. Therefore, the vehicle only needs to control the lighting system in the vehicle according to the multimedia audio. In the second working mode, the sound system is used for karaoke, but the user sets not to use the lighting system in the vehicle. Therefore, the vehicle only needs to control the lighting system in the audio acquisition device according to the multimedia audio. In the third working mode, the sound system is used for karaoke, and the user sets to use both the lighting system in the vehicle and the lighting system in the audio acquisition device simultaneously. Therefore, the vehicle synchronously controls the lighting system in the vehicle and the lighting system in the audio acquisition device according to the multimedia audio as needed.

[0086] For example, when the sound effects system is in the second operating mode, and the light effects system in the audio acquisition device is controlled according to the multimedia audio, such as... Figure 2 and Figure 3 As shown, the vehicle includes a microphone, receiver, in-vehicle infotainment system, PAD (in-vehicle tablet), external amplifier, and audio system. The microphone includes a lighting device. Data transmission between the microphone and receiver uses UHF (Ultra-High Frequency) and BLE (Bluetooth). After the human voice data is input to the microphone, it is transmitted via UHF to the receiver. After processing by the receiver's audio algorithms, it is transmitted to the in-vehicle infotainment system via USB (Universal Serial Bus). In the infotainment system, the human voice data and the accompanying audio from the PAD are mixed and sent to the amplifier for audio optimization before being output by the vehicle's audio system. Simultaneously, after the PAD sends the accompanying audio to the infotainment system, the audio is split into two paths. One path is mixed with the human voice audio from the receiver and output to the amplifier; the other path is a downlink audio link within the vehicle, transmitted to the receiver via USB. The receiver analyzes the accompanying audio and transmits the analyzed data to the microphone via BLE, controlling the microphone's lighting device to move in sync with the accompanying audio.

[0087] Further, step 1023 includes:

[0088] Step 10231: Control the vehicle's lighting system according to the multimedia audio, and obtain the lighting display parameters and light flashing frequency corresponding to the vehicle's lighting system;

[0089] In this step, after the vehicle's infotainment system determines that the sound system is in the third working mode, it processes the multimedia audio to obtain audio characteristics. Based on the audio characteristics, it determines the lighting display parameters and the light flashing frequency. Based on the lighting display parameters and the light flashing frequency, it controls the vehicle's lighting system. At the same time, it acquires the lighting display parameters and the light flashing frequency corresponding to the vehicle's lighting system and sends the lighting display parameters and the light flashing frequency to the audio acquisition device.

[0090] Step 10232: Synchronously control the light effect system in the audio acquisition device according to the light display parameters and the light flashing frequency.

[0091] In this step, the vehicle's infotainment system sends the lighting display parameters and flashing frequency to the audio acquisition device. Then, it controls the lighting system in the audio acquisition device to change the color and brightness of the lights and make them flash according to the lighting display parameters and flashing frequency. This achieves synchronous control between the lighting system in the vehicle and the lighting system in the audio acquisition device, allowing multiple light and shadow effects to work together to create a stronger karaoke atmosphere and improve the user's in-car karaoke experience.

[0092] Furthermore, the step of outputting the user audio and the multimedia audio through the sound effects system includes:

[0093] Step 1024: The user audio and the multimedia audio are mixed using the sound effects system to obtain the target audio;

[0094] Step 1025: The target audio is sent to the in-vehicle speaker and / or the external speaker for playback via the sound effect system.

[0095] In steps 1024 and 1025, the vehicle's infotainment system mixes the user audio and multimedia audio using a sound effects system to obtain the target audio; the target audio is then transmitted to the in-vehicle speakers and / or external speakers for playback. Specifically, refer to... Figure 4 The vehicle supports adding wireless external Bluetooth speakers as external speakers, allowing for simultaneous karaoke both inside and outside the vehicle. After the external speakers are paired with the vehicle's Bluetooth system, the vocals and accompaniment data are transmitted synchronously via the UHF signal from the built-in receiver. At this time, the external speakers can obtain the vocal signal processed by the receiver's DSP chip, achieving synchronization of the accompaniment and vocal signals inside and outside the vehicle.

[0096] In this embodiment, the vehicle's infotainment system collects user audio via an audio acquisition device and acquires multimedia audio from the central control system. It controls the lighting system within the audio acquisition device based on the multimedia audio and outputs both the user audio and the multimedia audio through a sound system. This allows the lighting system in the vehicle's audio acquisition device to be controlled based on the multimedia audio. Simultaneously, the sound system blends vocals and song accompaniment before outputting, creating a stronger karaoke atmosphere through the interplay of sound and light effects. This achieves visual and auditory synergy, enhancing the user's in-car karaoke experience.

[0097] Please refer to Figure 5 The second embodiment of this application is proposed. The difference between the second embodiment and the first embodiment is that the step of controlling the light effect system in the vehicle according to the multimedia audio includes:

[0098] Step 201: Process the multimedia audio to obtain audio features;

[0099] In this step, the vehicle's infotainment system processes the multimedia audio to obtain audio features, including pitch, rhythm, and melody.

[0100] Step 202: Determine the light display parameters and light flashing frequency based on the audio characteristics;

[0101] In this step, the vehicle's infotainment system determines the lighting display parameters and the lighting flashing frequency based on audio characteristics. The lighting display parameters include the color and brightness of the displayed lights. For example, the vehicle has pre-set mapping tables between audio characteristics and lighting display parameters, as well as between audio characteristics and lighting flashing frequencies. When the vehicle processes multimedia audio and obtains the audio characteristics, it can find the corresponding lighting display parameters in the mapping table based on the determined audio characteristics. Similarly, it can find the corresponding lighting flashing frequency in the mapping table based on the determined audio characteristics.

[0102] Step 203: Control the lighting system in the vehicle according to the light display parameters and the light flashing frequency.

[0103] In this step, the vehicle's infotainment system controls the lighting devices in the vehicle's lighting system to display the corresponding colors and brightness based on the lighting display parameters and the lighting flashing frequency, and controls the lighting devices in the vehicle's lighting system to flash based on the lighting flashing frequency.

[0104] Specifically, step 203 includes:

[0105] Step 2031: Generate a pulse width modulation signal based on the light flashing frequency;

[0106] In this step, the vehicle's infotainment system generates a pulse width modulation (PWM) signal based on the obtained headlight flashing frequency. Specifically, the headlights in the vehicle's lighting system flash by repeatedly switching them on and off. The flashing frequency indicates the interval between the switching on and off of the headlights. The generated PWM signal is a signal that alternates between high and low levels; a high level controls the headlights to turn on, and a low level controls the headlights to turn off, thus achieving the flashing of the headlights.

[0107] Step 2032: Generate a color control signal and a brightness control signal based on the light display parameters;

[0108] In this step, the vehicle's infotainment system acquires the color and brightness parameters from the lighting display parameters. It generates a color control signal based on the color parameter and a brightness control signal based on the brightness parameter. Specifically, the lighting display parameters use RGB values, which can represent both color and brightness. For example, when the RGB value is (255,0,0), the vehicle adjusts the lighting system to display red, as the R value for red is 255, resulting in maximum brightness. When the RGB value is (139,0,0), the vehicle's infotainment system adjusts the lighting system to display dark red, as the R value for red is relatively small (139), resulting in lower brightness. Therefore, the vehicle's infotainment system can generate color and brightness control signals based on the corresponding RGB values ​​of the lighting display parameters.

[0109] Step 2033: Control the lighting device in the vehicle's lighting system to flash based on the pulse width modulation signal, and control the color and brightness displayed by the lighting device in the vehicle's lighting system based on the color control signal and the brightness control signal.

[0110] In this step, the vehicle's infotainment system inputs a pulse width modulation (PWM) signal into the vehicle's lighting system to control the lights in the lighting system to blink according to the high and low levels of the PWM signal; the vehicle's infotainment system also inputs color control signals and brightness control signals into the vehicle's lighting system to control the lights in the lighting system to display the corresponding color according to the color control signal, and to control the lights in the lighting system to adjust the brightness of the displayed color according to the brightness control signal.

[0111] In this embodiment, the vehicle's infotainment system processes multimedia audio to obtain audio characteristics; it then determines lighting display parameters and flashing frequency based on these characteristics; and finally, it controls the vehicle's lighting system according to these parameters and flashing frequency. This allows the vehicle's lighting system to change according to the multimedia audio, enhancing the fun and atmosphere of in-car karaoke and thus improving the user's overall karaoke experience.

[0112] Please refer to Figure 6 The third embodiment of this application is proposed. The difference between the third embodiment and the first and second embodiments is that the step of controlling the light effect system in the audio acquisition device according to the multimedia audio includes:

[0113] Step 301: Process the multimedia audio to obtain audio features; the audio features represent the level changes of the multimedia audio.

[0114] In this step, after acquiring the multimedia audio, the vehicle's infotainment system processes the multimedia audio to obtain audio features; the audio features represent the level changes of the multimedia audio. Specifically, the infotainment system performs frame-by-frame processing on the multimedia audio to obtain a set of audio frames. For each audio frame in the audio frame set, the infotainment system calculates the average level value of each audio frame and maps the average level value to a range of 0 to 255 as the audio feature.

[0115] Specifically, the processing of the multimedia audio to obtain audio features includes:

[0116] Step 3011: Filter the multimedia audio to obtain the target audio;

[0117] In this step, the vehicle's infotainment system filters the multimedia audio to obtain the target audio. Specifically, the infotainment system performs a low-pass filter on the multimedia audio, filtering out the audio frequencies above 500Hz and retaining the frequencies at or below 500Hz to obtain the target audio.

[0118] Step 3012: Based on a preset duration, the target audio is divided into frames to obtain audio frames;

[0119] In this step, the vehicle's infotainment system performs frame-by-frame processing on the target audio based on a preset duration, resulting in audio frames. For example, the preset duration is 50ms, and the vehicle's infotainment system performs frame-by-frame processing on the target audio in 50ms increments, resulting in multiple audio frames.

[0120] Step 3013: Process the level information of each audio frame to obtain the audio features corresponding to each audio frame.

[0121] In this step, the vehicle's infotainment system processes the level information of each audio frame to obtain the average level value of each audio frame, and maps the average level value to a range of 0-255 as an audio feature. Specifically, for each audio frame, the infotainment system applies a window function (such as a Hamming window or Hanning window) to reduce spectral leakage and endpoint effects; for the data of each audio frame, its root mean square value is calculated, which is the square root of the average of the sum of squares of each sample point. The specific formula is: Where, x i Here, is the audio data of the i-th sample point, N is the number of samples in each audio frame, and RMS is the average level value. After determining the average level value of each audio frame, the vehicle-mounted system determines the minimum and maximum level values ​​of the target audio. Based on the average level value, minimum level value, and maximum level value, the average level value is mapped to a range of 0 to 255 as an audio feature. The specific formula is as follows: Where DATA represents the audio characteristics, RMS represents the average level value, and RMS represents the average level value. min This is the minimum level value. RMS max This is the maximum voltage level.

[0122] Step 302: Control the light effect system in the audio acquisition device according to the audio characteristics.

[0123] In this step, the vehicle's infotainment system compares the audio features corresponding to two adjacent audio frames and controls the light effect system in the audio acquisition device based on the comparison results.

[0124] Specifically, step 302 includes:

[0125] Step 3021: Determine the level corresponding to each audio frame based on the audio characteristics;

[0126] In this step, the vehicle's infotainment system determines the level of each audio frame based on its audio characteristics and a pre-defined mapping between audio characteristics and frequency levels. For example, the audio characteristics obtained by the vehicle's infotainment system are average level values ​​mapped to the range of 0-255. The system divides 0-255 into 30 level levels, assigning every 8 consecutive values ​​within the range to one level, and assigning 240-255 to the last level. Based on the audio characteristics of each audio frame, the system determines which value within 0-255 corresponds to the audio characteristic, and then determines the level of the audio frame based on which level the audio characteristic value falls into.

[0127] Step 3022: Compare the level levels corresponding to the audio frames to control the light effect system in the audio acquisition device.

[0128] In this step, the vehicle's infotainment system compares the audio level corresponding to each audio frame to control the lighting system in the audio acquisition device. Specifically, the audio frames are received by the infotainment system frame by frame in the playback order of the multimedia audio. At this time, the infotainment system compares the level corresponding to the currently received audio frame with the level corresponding to the previously received audio frame, and then controls the lighting system in the audio acquisition device based on the comparison result.

[0129] Specifically, step 3022 includes:

[0130] Step 30221: If the level of the current audio frame is higher than the level of the reference audio frame, then control the light device in the light effect system to blink; the reference audio frame is the previous audio frame before the current audio frame.

[0131] In this step, the vehicle's infotainment system compares the level of the current audio frame with the level of the reference audio frame. If it determines that the level of the current audio frame is higher than that of the reference audio frame, it controls the lights in the lighting system to flash. The reference audio frame is the previous audio frame received by the vehicle's infotainment system before receiving the current audio frame.

[0132] Furthermore, when the lighting device in the vehicle's infotainment system flashes, the lighting parameters of the lighting device in the system are determined based on the audio characteristics corresponding to the current audio frame.

[0133] Step 30222: If the level of the current audio frame is lower than the level of the reference audio frame, then determine the lighting parameters of the lighting device in the lighting system based on the audio characteristics of the current audio frame.

[0134] In this step, the vehicle's infotainment system compares the level of the current audio frame with the level of the reference audio frame. If the level of the current audio frame is lower than that of the reference audio frame, the lighting parameters of the lighting device in the lighting system are determined based on the audio characteristics of the current audio frame. Then, the color or intensity of the light displayed by the lighting device in the lighting system is adjusted according to the lighting parameters.

[0135] For example, the vehicle's infotainment system calculates the lighting parameters of the lighting device in the lighting system based on the audio features corresponding to the current audio frame as weights. The lighting parameters are the RGB values ​​of the colors that the lighting device needs to display. When the RGB value is (255, 128, 128), the vehicle's infotainment system adjusts the color of the lighting device in the lighting system to light red based on (255, 128, 128). When the RGB value is (255, 0, 0), the vehicle's infotainment system adjusts the color of the lighting device in the lighting system to red based on (255, 0, 0). When the RGB value is (139, 0, 0), the vehicle's infotainment system adjusts the color of the lighting device in the lighting system to dark red based on (139, 0, 0).

[0136] Further, before determining the level corresponding to each audio frame based on the audio features, the process includes:

[0137] Step a1: If the audio feature is not the same as the reference audio feature, then perform the following step: determine the level corresponding to each audio frame based on the audio feature; the reference audio feature is the audio feature corresponding to the previous audio frame before the current audio frame.

[0138] Step a2: If the audio feature is the same as the reference audio feature, then control the light effect system in the audio acquisition device according to the preset light effect control rules.

[0139] In steps a1 to a2, when the vehicle's infotainment system receives the current audio frame, it first compares the audio feature corresponding to the current audio frame with the reference audio feature corresponding to the reference audio frame. The reference audio frame is the previous audio frame received by the vehicle's infotainment system before receiving the current audio frame, and the reference audio feature is the audio feature corresponding to the previous audio frame received by the vehicle's infotainment system before receiving the current audio frame. If the vehicle's infotainment system determines that the audio feature corresponding to the current audio frame is different from the audio feature corresponding to the reference audio frame, it can determine that the multimedia audio is still playing, and then continues to execute the step: determining the level corresponding to each audio frame according to the audio feature. If the vehicle's infotainment system determines that the audio feature corresponding to the current audio frame is the same as the audio feature corresponding to the reference audio frame, it can determine that the multimedia audio has finished playing. At this time, the vehicle's infotainment system controls the light effect system in the audio acquisition device according to the preset light effect control rules, wherein the preset light effect control rules are the color change rules of the light effect system in the audio acquisition device when no multimedia music is playing.

[0140] In this embodiment, the vehicle's infotainment system processes multimedia audio to obtain audio features corresponding to each audio frame. Based on the comparison between the audio features corresponding to the current audio frame and the audio features corresponding to the previous audio frame, the system controls the lighting system in the audio acquisition device. This allows the color and intensity of the lights in the lighting system to change based on the multimedia audio, enhancing the fun and atmosphere of karaoke in the car and improving the overall karaoke experience.

[0141] refer to Figure 7 The fourth embodiment of this application is proposed. The difference between the fourth embodiment and the first to third embodiments is that, before controlling the light effect system in the audio acquisition device according to the multimedia audio, the following steps are included:

[0142] Step 401: When no multimedia audio is received from the central control system, control the light effect system in the audio acquisition device according to the preset light effect control rules;

[0143] In this step, after the vehicle's infotainment system powers on the audio acquisition device but does not receive multimedia audio from the central control system, it controls the lighting system in the audio acquisition device according to preset lighting control rules. Specifically, the preset lighting control rules are as follows: the lighting device in the audio acquisition device cycles through five basic colors—red, yellow, blue, green, and purple—changing one basic color every 10 seconds. The intervals between the basic colors are filled with gradient colors, each basic color lasts for 8 seconds, and the gradient color is completed within 2 seconds.

[0144] Furthermore, controlling the light effect system in the audio acquisition device according to the multimedia audio includes:

[0145] Step 402: If multimedia audio is received from the central control system, the light effect system in the audio acquisition device is controlled based on the current light effect information of the light effect system and the multimedia audio.

[0146] In this step, when the vehicle's infotainment system receives multimedia audio from the central control system, it controls the lighting system in the audio acquisition device based on the current lighting information of the lighting system and the multimedia audio. Specifically, if the current lighting information of the lighting system is in the basic color (red, yellow, green, blue, purple), then upon receiving multimedia audio from the central control system, the system controls the lighting device in the audio acquisition device to use this basic color as the starting color for rhythmic movement. In the initial stage of controlling the lighting system in the audio acquisition device, the lighting device stays in this basic color for a target duration before changing color according to the multimedia audio. The target duration is the difference between the preset basic color dwell time and the dwell time of the basic color when no multimedia audio is received. For example, if the preset basic color dwell time is 8 seconds and the dwell time of the basic color when no multimedia audio is received is 3 seconds, then in the initial stage of controlling the lighting system in the audio acquisition device, the lighting device stays in this basic color for 5 seconds before changing color according to the multimedia audio. 2. When the current lighting effect information of the lighting system is in a gradient color, upon receiving multimedia audio from the central control system, the lighting device of the lighting system in the audio acquisition device will use this gradient color as the starting color to rhythmically change. In the initial stage of controlling the lighting system in the audio acquisition device, the lighting device of the lighting system will remain in the gradient color for a target duration, and then change color according to the multimedia audio. The target duration is the difference between the preset gradient color dwell time and the dwell time of the gradient color when no multimedia audio is received. For example, if the preset gradient color dwell time is 2 seconds and the gradient color dwell time when no multimedia audio is received is 1 second, then in the initial stage of controlling the lighting system in the audio acquisition device, the lighting device of the lighting system will remain in the gradient color for 1 second, and then change color according to the multimedia audio.

[0147] Furthermore, when the vehicle's infotainment system determines that multimedia audio playback has finished, if the current lighting information of the lighting system is in the basic color (red, yellow, green, blue, purple), then upon determining that the multimedia audio playback has finished, the system controls the lighting device of the lighting system in the audio acquisition device to rhythmically move using this basic color as the starting color. The lighting device of the lighting system stays in this basic color for a target duration before switching to the next color. The target duration is the difference between the preset basic color dwell time and the dwell time of the basic color when receiving multimedia audio. For example, if the preset basic color dwell time is 8 seconds and the basic color dwell time when receiving multimedia audio is 5 seconds, then upon determining that the multimedia audio playback has finished, the system controls the lighting device of the lighting system to stay in this basic color for 3 seconds before switching to the next color. 2. When the current lighting effect information of the lighting system is in a gradient color, upon determining that the multimedia audio playback has ended, the lighting device of the lighting system in the audio acquisition device is controlled to use this gradient color as the starting color for rhythmic movement. The lighting device of the lighting system stays in this base color for a target duration before switching to the next color. The target duration is the difference between the preset gradient color dwell time and the gradient color dwell time when the multimedia audio is received. For example, if the preset gradient color dwell time is 2 seconds and the gradient color dwell time when the multimedia audio is received is 0.5 seconds, then upon determining that the multimedia audio playback has ended, the lighting device of the lighting system is controlled to stay in this gradient color for 1.5 seconds before switching to the next color.

[0148] In this embodiment, the vehicle's infotainment system controls the lighting system in the audio acquisition device according to preset lighting control rules when no multimedia audio is received from the central control system. When multimedia audio is received from the central control system, the system controls the lighting system in the audio acquisition device based on the current lighting information of the lighting system and the multimedia audio. This prevents sudden color changes in the lighting devices of the audio acquisition device from disrupting the fun and atmosphere of in-car karaoke, thereby improving the user's in-car karaoke experience.

[0149] refer to Figure 8 The fifth embodiment of this application is proposed. The difference between the fifth embodiment and the first to fourth embodiments is that, after the user's audio is collected by the audio acquisition device, the process includes:

[0150] Step 501: Send the user audio to the main control screen corresponding to the multimedia audio, so that the main control screen generates and displays audio interaction information based on the user audio and the multimedia audio;

[0151] Step 502: Send the audio interaction information to other screens besides the main control screen so that the other screens display the audio interaction information.

[0152] In steps 501 to 502, when the vehicle's infotainment system receives multimedia audio and user audio, it sends the user audio to the main control screen corresponding to the multimedia audio, so that the main control screen generates and displays audio interaction information based on the user audio and multimedia audio. Simultaneously, it sends the audio interaction information to other screens besides the main control screen, so that these other screens display the audio interaction information. For example, as... Figure 9 As shown, the main control screen for multimedia audio is the vehicle's main control screen. Other screens include the rear-seat screen and the passenger-side screen. The microphone transmits the user's audio to the vehicle's infotainment system via USB through a receiver. The system identifies the screen currently using the karaoke app as the main control screen and distributes the user's audio to the corresponding screen. The main control screen can score the user's karaoke performance based on both the user's audio and the multimedia audio, and display the score. Furthermore, the system can send the karaoke score, the music video, and lyrics to the rear-seat screen and the passenger-side screen, enabling multi-screen interconnected karaoke and allowing users in each location to easily view the music video and lyrics.

[0153] The vehicle infotainment system in this embodiment can generate and display audio interaction information on the main control screen based on user audio and multimedia audio, which can enhance the in-cabin entertainment experience. At the same time, it can send audio interaction information to other screens besides the main control screen so that other screens can display audio interaction information, enabling multiple users to participate and enhancing the fun of karaoke.
