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

[0028] The following describes the background dynamic rhythm switching method, device, and vehicle based on the music genre of the embodiment of the present application with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that the current music software generally has a fixed cover or background dynamic effect when playing, and the intelligence is low, the present application provides a background dynamic rhythm switching method based on the music genre, in which it is determined whether a background dynamic rhythm switching request is received. 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, the current music playback mode of the vehicle is switched to the target music playback mode, and / or the current music playback background of the vehicle is switched to the target music playback background, and the ambient light is controlled to rhythm based on the ambient light rhythm strategy corresponding to the target music playback mode. As a result, the problem that the current music software generally has a fixed cover or background dynamic effect when playing, and the intelligence is low is solved, and the aggregation of the car-machine music background and rhythm is realized, thereby improving the user's driving experience.

[0029] Specifically, Figure 1 A flowchart of a background dynamic rhythm switching method based on music genre provided in an embodiment of the present application.

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

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

[0032] Among them, the background dynamic rhythm switching request can be issued by the user clicking the switch button of the music player, or through the voice of the voice assistant.

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

[0034] Among them, the target music playback modes include random mode and rhythm mode, and the rhythm mode includes line mode, square mode, circle mode, etc.

[0035] In step S103, the current music playback mode of the vehicle is switched to the target music playback mode, and / or the current music playback background of the vehicle is switched to the target music playback background, and the ambient light is controlled to move according to the ambient light rhythm strategy corresponding to the target music playback mode.

[0036] Optionally, in some embodiments, the current music playback mode of the vehicle is switched to the target music playback mode, including: if the background dynamic rhythm switching request is a line mode switching request, processing the pulse code modulation PCM audio data, converting the PCM audio data into a digital signal representing an audio energy value, and adjusting the moving speed of the line according to the energy value; if the background dynamic rhythm switching request is a block mode switching request, controlling the up and down swing of the block according to the energy value; if the background dynamic rhythm switching request is a switching request, adjusting the moving speed of the circle according to the energy value.

[0037] Specifically, Figure 2 As shown, the embodiment of the present 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. Among them, each music genre designs a corresponding default music playback background and music rhythm mode, and the music rhythm mode can be displayed by stars, petals, lines, etc., among which the music genres include pop genre, electronic genre, light music genre, folk genre, rap genre, rock genre, jazz genre, R&B genre, blues genre, classical genre, post-rock genre, ancient style genre, Chinese style genre, etc.

[0038] Currently, music apps are all aggregation apps. Bluetooth and USB music can use the default background. QQ, NetEase, Kugou, etc. design music playback backgrounds that match their types based on the music genres returned by the third-party SDK interface.

[0039] If there is an atmosphere light, the PCM data processed by the atmosphere light can be directly called. If there is no atmosphere light, the PCM data is collected and then the spectrum is analyzed to obtain the energy value data. The rhythmic resources jump regularly according to the energy value.

[0040] When music is playing, the rhythmic resources adapt to the entire screen and beat regularly according to the energy value. The beating methods of the rhythmic resources include the speed of the lines moving left and right on the screen, the height and speed of the blocks jumping up and down, and the speed of circles. At the same time, the atmosphere light beats according to the target music playback mode. The rhythm pauses when the music is paused. The default music playback background and music rhythm mode are applied when music is playing. Users can select the target music rhythm mode and target music playback background.

[0041] As an embodiment, specifically, if the background dynamic rhythm switching request is a line mode, 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 speed of the energy value; if the background dynamic rhythm switching request is a square mode, a rectangle is displayed on the music playback interface, and swings up and down according to the energy value; if the background dynamic rhythm switching request is a circle mode, the middle resources of the screen form 5-10 circles that move clockwise according to the energy value.

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

[0043] It should be understood that whenever the music player is connected to the Internet, the music player will automatically retrieve the latest music playback background (such as high-definition pictures, dynamic wallpapers) and the latest music playback mode (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 start downloading these resources and store them in the local device or cloud storage for subsequent use.

[0044] After 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. The user can choose to view and apply these new resources.

[0045] Optionally, in some embodiments, the above-mentioned background dynamic rhythm switching method based on music genre also includes: deleting music playback backgrounds and music playback modes that are repeated or 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 the music playback backgrounds and music playback modes.

[0046] It should be understood that the music playback background and music playback mode that do not meet the preset quality conditions may be a music playback background and music playback mode with lower resolution, a music playback background and music playback mode with lower user ratings, and so on.

[0047] To keep the resource library tidy and efficient, the music player will automatically check and delete music backgrounds and music playback modes that are duplicate or do not meet preset quality requirements based on preset time intervals (such as weekly or monthly). For example, the music backgrounds and music playback modes have small files, low resolutions, low user ratings, or conflict with other resources.

[0048] The music player uses machine learning algorithms to analyze user preferences based on the user's actual usage of music playback backgrounds and music playback modes (such as click-through rate, playback time, user ratings, etc.), and intelligently recommends new music playback backgrounds and new music playback modes that are highly relevant to the user's preferences.

[0049] Optionally, in some embodiments, after the current music playback mode of the vehicle is switched to the target music playback mode, the process includes: storing the target music playback mode in a cloud server, and automatically loading a query instruction for the target music playback mode when the user starts the music player next time; if a confirmation instruction for entering the target music playback mode is received from the user based on the query instruction, the target music playback mode is directly entered.

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

[0051] When the user starts the music player next time, the music player will send a query command to the user, asking the user whether he wants to directly enter the target music playback mode saved last time. If the user confirms this command within a certain period of time by clicking, voice response or gesture, the music player will immediately load and apply the target music playback mode saved last time. If the user chooses not to enter the target music playback mode saved last time, the music player will return to the default playback state or adjust according to the user's latest selection.

[0052] In order to enable those skilled in the art to further understand the background dynamic rhythm switching method based on music genres in the embodiment of the present application, it is described in detail below in conjunction with specific embodiments. Figure 3 shown.

[0053] Step 1: According to the type of aggregation, USB, Bluetooth, etc., design a set of default background and rhythm resources, and obtain and classify song genres through QQ, Kugou, etc.

[0054] Step 2: If the third-party genres 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, then all genre types are sorted out.

[0055] Step 3: UI designs the background and rhythm resources corresponding to each genre type according to all genre types, and after completion, converts them into png format and gives them to the corresponding development.

[0056] Step 4: Connect to the PCM data interface collected and converted by the ambient light, register and call back.

[0057] Step 5: Get the mode selected by the user. Each genre has a default music background and music rhythm mode. In random mode, the music background and music mode are randomly selected when switching songs; in rhythm mode, if it is line mode, the resources are combined into a line that moves from left to right according to the energy value. If it is square mode, the resources are combined into a rectangle that swings up and down according to the energy value. If it is circle mode, the resources in the middle 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 and the data transmitted by the PCM is received and processed, and the rhythm is performed according to the rhythm mode selected by the user. The rhythm is paused when the music is paused.

[0059] Step 7: The process ends.

[0060] According to the background dynamic rhythm switching method based on music genres proposed in the embodiment of the present application, it is determined whether a background dynamic rhythm switching request is received. 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, the current music playback mode of the vehicle is switched to the target music playback mode, and / or the current music playback background of the vehicle is switched to the target music playback background, and the ambient light is controlled to rhythm based on the ambient light rhythm strategy corresponding to the target music playback mode. In this way, the problem that the current music software generally has a fixed cover or a fixed background dynamic effect when playing, and the intelligence is low is solved, and the aggregation of the car computer music background and rhythm is realized, thereby improving the user's driving experience.

[0061] Next, a background dynamic rhythm switching device based on music genres proposed in an embodiment of the present application will be described with reference to the accompanying drawings.
