[0027] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0028] The following description, with reference to the accompanying drawings, describes a method, apparatus, and vehicle for background dynamic rhythm switching based on music genres according to embodiments of this application. Addressing the issue mentioned in the background art that current music software typically uses fixed album art or background animations with low intelligence, this application provides a method for background dynamic rhythm switching based on music genres. In this method, it is determined whether a background dynamic rhythm switching request has been received. If so, a target music playback background, a target music playback mode, and a corresponding ambient light rhythm strategy are determined based on the request. The vehicle's current music playback mode is switched to the target music playback mode, and / or the vehicle's current music playback background is switched to the target music playback background. The ambient lights are then controlled to rhythmically move according to the ambient light rhythm strategy corresponding to the target music playback mode. This solves the problem of current music software typically using fixed album art or background animations with low intelligence, achieving the aggregation of in-vehicle music background and rhythm, and improving the user's driving experience.

[0029] Specifically, Figure 1 This is a flowchart illustrating a method for switching background dynamics based on music genres, provided in an embodiment of this application.

[0030] like Figure 1 As shown, this method for background dynamic rhythm switching based on music genre includes the following steps:

[0031] In step S101, it is determined whether a background dynamic rhythm switching request has been received.

[0032] The background dynamic rhythm switching request can be issued by the user clicking the switch button on the music player or by speaking through the voice assistant.

[0033] In step S102, if a background dynamic rhythm switching request is received, the target music playback background, the target music playback mode, and the ambient light rhythm strategy corresponding to the target music playback mode are determined based on the background dynamic rhythm switching request.

[0034] The target music playback modes include random mode and rhythm mode. The rhythm mode includes line mode, square mode, and spinning mode.

[0035] In step S103, the vehicle's current music playback mode is switched to the target music playback mode, and / or the vehicle's current music playback background is switched to the target music playback background, and the ambient lights are controlled to rhythm based on the ambient light rhythm strategy corresponding to the target music playback mode.

[0036] Optionally, in some embodiments, switching the vehicle's current music playback mode to a target music playback mode includes: if the background dynamic rhythm switching request is a line mode switching request, then processing pulse code modulation (PCM) audio data, converting the PCM audio data into a digital signal representing the audio energy value, and adjusting the movement speed of the lines according to the energy value; if the background dynamic rhythm switching request is a block mode switching request, then controlling the up-and-down swing of the blocks according to the energy value; if the background dynamic rhythm switching request is a switching request, then adjusting the movement speed of the circles according to the energy value.

[0037] Specifically, such as Figure 2 As shown, this embodiment of the application obtains the current music genre of the current song and designs the corresponding current music playback background and current music playback mode according to the type of the current music genre. Each music genre has a corresponding default music playback background and music rhythm mode, which can be displayed using stars, petals, lines, etc. Music genres include pop, electronic, light music, folk, rap, rock, jazz, R&B, blues, classical, post-rock, traditional Chinese style, and Chinese style, etc.

[0038] Currently, music apps are mostly aggregation apps. Bluetooth and USB music can use the default background, while apps like QQ Music, NetEase Music, and Kugou Music design their own music playback backgrounds based on the music genres returned by third-party SDK interfaces.

[0039] If there is ambient lighting, the PCM data processed by the ambient lighting can be directly accessed. If there is no ambient lighting, the PCM data is collected and then the energy value data is obtained through spectrum analysis. The rhythmic resources jump regularly according to the energy value.

[0040] When music plays, the rhythmic elements adapt to the entire screen, jumping rhythmically according to the energy value. The jumping patterns of the rhythmic elements include the speed at which lines move left and right on the screen, the height at which squares jump up and down, and the speed at which they rotate. At the same time, the ambient lights rhythmize according to the target music playback mode. The rhythm stops when the music is paused. The default music playback background and music rhythm mode are applied when music is playing, but users can select the target music rhythm mode and target music playback background.

[0041] As one embodiment, specifically, if the background dynamic rhythm switching request is a line mode, then the pulse code modulation (PCM) audio data is processed, the PCM audio data is converted into a digital signal representing the audio energy value, and a line is displayed on the music playback interface, moving from left to right according to the energy value; if the background dynamic rhythm switching request is a square mode, then a rectangle is displayed on the music playback interface, and it swings up and down according to the energy value; if the background dynamic rhythm switching request is a rotating mode, then 5-10 circles formed by resources in the middle of the screen move clockwise according to the energy value.

[0042] Optionally, in some embodiments, the above-described background dynamic rhythm switching method based on music genre further includes: automatically retrieving and downloading the latest music playback background and the latest music playback mode; and sending a notification to the user through the user interface of the music player to update the music playback background and music playback mode.

[0043] It should be understood that whenever a music player connects to the internet, it automatically searches for the latest music playback backgrounds (such as high-definition images and live wallpapers) and the latest music playback modes (such as animation effects and visual effects templates synchronized with the music rhythm). Once a new music playback mode is detected, the music player will immediately begin downloading these resources and storing them on the local device or in cloud storage for later use.

[0044] Once the download is complete, the music player will appear in the form of a pop-up window, banner, or notification bar message to inform the user that new music playback backgrounds and music playback modes are available. Users can choose to view and apply these new resources.

[0045] Optionally, in some embodiments, the above-described background dynamic rhythm switching method based on music genre further includes: deleting duplicate music playback backgrounds and music playback modes that do not meet preset quality conditions based on preset time intervals, and intelligently recommending new music playback backgrounds and new music playback modes based on the user's actual usage of music playback backgrounds and music playback modes.

[0046] It should be understood that music playback backgrounds and modes that do not meet the preset quality conditions may be music playback backgrounds and modes with lower resolution, music playback backgrounds and modes with lower user ratings, etc.

[0047] To keep the resource library clean and efficient, the music player automatically checks and deletes duplicate or substandard music playback backgrounds and modes at preset time intervals (e.g., weekly, monthly), such as when the music playback background or mode file is too small, has a low resolution, a low user rating, or conflicts with other resources.

[0048] Music players use machine learning algorithms to analyze user preferences based on actual usage data (such as click-through rate, playback duration, user ratings, etc.) of music playback backgrounds and modes, and intelligently recommend new music playback backgrounds and modes that are highly relevant to the user's preferences.

[0049] Optionally, in some embodiments, after switching the vehicle's current music playback mode to the target music playback mode, the process includes: storing the target music playback mode in a cloud server and automatically loading a query command for the target music playback mode when the user launches the music player next time; if a confirmation command to enter the target music playback mode is received from the user based on the query command, the user directly enters the target music playback mode.

[0050] Specifically, when a user switches the current music playback mode to a target playback mode or target music playback background, the music player will store the target playback mode and target music playback background in the cloud server.

[0051] When a user launches the music player again, the music player will send a prompt to the user, asking if the user wants to directly enter the last saved target music playback mode. If the user confirms this prompt within a certain time through clicking, voice response, or gesture, the music player will immediately load and apply the last saved target music playback mode. If the user chooses not to enter the last saved target music playback mode, the music player will return to the default playback state or adjust according to the user's latest selection.

[0052] To enable those skilled in the art to further understand the background dynamic rhythm switching method based on music genre in the embodiments of this application, the following detailed description is provided in conjunction with specific embodiments, such as... Figure 3 As shown.

[0053] Step 1: Categorize according to aggregation type. Design a default set of background and rhythm resources for USB and Bluetooth, and obtain and categorize song genres from QQ, Kugou, etc.

[0054] Step 2: If the genres of the third-party music are consistent, the same dynamic background video can be used. If there are differences, and the aggregated source has two or more third-party music sources, then all genre types are sorted out.

[0055] Step 3: The UI designer creates background and rhythm resources for each genre, and then converts them into PNG format for the corresponding development team.

[0056] Step 4: Connect to the interface for collecting and converting PCM data from the ambient light, register and call back.

[0057] Step 5: Obtain the user-selected mode. Each genre has a default music playback background and music rhythm mode. In random mode, the music playback background and mode are randomly selected when switching songs. In rhythm mode, if it's line mode, the resources are combined into a line that moves from left to right according to the energy value; if it's square mode, the resources are combined into a rectangle that swings up and down according to the energy value; if it's rotating mode, the resources in the center of the screen form 5-10 circles that move clockwise according to the energy value.

[0058] Step 6: When the music is playing, the rhythm starts receiving and processing the data transmitted from the PCM and rhythms according to the rhythm mode selected by the user. The rhythm stops when the music stops.

[0059] Step 7: Process ends.

[0060] According to the background dynamic rhythm switching method based on music genre proposed in this application, it is determined whether a background dynamic rhythm switching request has been received. If a background dynamic rhythm switching request is received, the target music playback background, target music playback mode, and ambient light rhythm strategy corresponding to the target music playback mode are determined based on the background dynamic rhythm switching request. The vehicle's current music playback mode is switched to the target music playback mode, and / or the vehicle's current music playback background is switched to the target music playback background. The ambient light is then controlled to rhythmically move according to the ambient light rhythm strategy corresponding to the target music playback mode. This solves the problem that current music software typically uses fixed album art or background animations, resulting in low intelligence. It achieves the aggregation of in-vehicle music background and rhythm, improving the user's driving experience.

[0061] Next, referring to the accompanying drawings, a background dynamic rhythm switching device based on music genres is described according to an embodiment of this application.

[0062] Figure 4 This is a block diagram of a background dynamic rhythm switching device based on music genre according to an embodiment of this application.

[0063] like Figure 4 As shown, the background dynamic rhythm switching device 10 based on music genre includes: a judgment module 100, a determination module 200 and a switching module 300.

[0064] The system includes a judgment module 100, which determines whether a background dynamic rhythm switching request has been received; a determination module 200, which, if a background dynamic rhythm switching request is received, determines the target music playback background, the target music playback mode, and the ambient light rhythm strategy corresponding to the target music playback mode based on the background dynamic rhythm switching request; and a switching module 300, which switches the vehicle's current music playback mode to the target music playback mode, and / or switches the vehicle's current music playback background to the target music playback background, and controls the ambient light to rhythm based on the ambient light rhythm strategy corresponding to the target music playback mode.

[0065] Optionally, in some embodiments, the switching module 300 is further configured to: if the background dynamic rhythm switching request is a line mode switching request, process pulse code modulation (PCM) audio data, convert the PCM audio data into a digital signal representing the audio energy value, and adjust the movement speed of the lines according to the energy value; if the background dynamic rhythm switching request is a square mode switching request, control the up-and-down swing of the square according to the energy value; if the background dynamic rhythm switching request is a switching request, adjust the movement speed of the circle according to the energy value.

[0066] Optionally, in some embodiments, the background dynamic rhythm switching device 10 based on music genre described above further includes: a download module for automatically retrieving and downloading the latest music playback background and the latest music playback mode; and a notification module for sending a notification to the user through the user interface of the music player to update the music playback background and music playback mode.

[0067] Optionally, in some embodiments, the background dynamic rhythm switching device 10 based on music genre described above further includes: a recommendation module, used to delete duplicate music playback backgrounds and music playback modes that do not meet preset quality conditions based on preset time intervals, and to intelligently recommend new music playback backgrounds and new music playback modes based on the user's actual usage of music playback backgrounds and music playback modes.

[0068] Optionally, in some embodiments, after switching the vehicle's current music playback mode to the target music playback mode, the switching module 300 is further configured to: store the target music playback mode in a cloud server and automatically load the query command for the target music playback mode when the user starts the music player next time; if a confirmation command to enter the target music playback mode is received from the user based on the query command, the target music playback mode is directly entered.

[0069] It should be noted that the foregoing explanation of the background dynamic rhythm switching method embodiment based on music genre also applies to the background dynamic rhythm switching device based on music genre in this embodiment, and will not be repeated here.

[0070] According to the background dynamic rhythm switching device based on music genre proposed in this application, it determines whether a background dynamic rhythm switching request has been received. If a background dynamic rhythm switching request is received, it determines the target music playback background, the target music playback mode, and the ambient light rhythm strategy corresponding to the target music playback mode based on the background dynamic rhythm switching request. It then switches the vehicle's current music playback mode to the target music playback mode and / or switches the vehicle's current music playback background to the target music playback background, and controls the ambient lights to rhythmically move according to the ambient light rhythm strategy corresponding to the target music playback mode. This solves the problem that current music software typically uses fixed album art or background animations, resulting in low intelligence. It achieves the aggregation of in-vehicle music background and rhythm, improving the user's driving experience.
