[0053] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0054] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0055] The main solution of the embodiment of the present application is: by providing an adjustable reflector on the back of the upper cover of the liftable speaker cover, multimedia playback instructions are obtained; data to be played is determined according to the multimedia playback instructions; a target reflection angle is determined based on the data to be played; and the adjustable reflector is adjusted according to the target reflection angle to realize vehicle multimedia playback control.

[0056] In the prior art, a reflector with a special angle is usually set on the back of the speaker cover to improve the sound reflection effect and enhance the performance of the high-frequency range. According to the research on the influence of the bulge on the back of the speaker cover (i.e. the angle of the reflector) on the high-frequency range, it is found that at the same frequency, as the angle of the reflector changes, the degree of decline in the high-frequency range varies. However, the reflectors on the back of the lifting speaker covers of the models currently on the market are all fixed structures and cannot be adjusted in angle.

[0057] The present application provides a solution, which includes setting an adjustable reflector plate, obtaining the optimal reflection angle through audio analysis, and then adjusting the angle of the reflector plate to make the reflection angle at the global optimal angle for high-frequency performance, thereby highlighting the layering of the sound and enhancing the passengers' sound experience and sense of driving technology.

[0058] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle multimedia playback control device, etc. The following takes the vehicle multimedia playback control device as an example to illustrate this embodiment and the following embodiments.

[0059] Based on this, the embodiment of the present application provides a vehicle multimedia playback control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle multimedia playback control method of the present application.

[0060] In this embodiment, the vehicle multimedia playback control method includes steps S10 to S40:

[0061] The vehicle multimedia playback control method is applied to a speaker cover on a vehicle, and the speaker cover is provided with an adjustable reflection plate facing the sound source.

[0062] It should be noted that if Figure 2 As shown, Figure 2A cross-sectional schematic diagram of a speaker cover includes a speaker generator and a speaker cover on the upper part of the speaker generator. An adjustable reflector is provided on the triangular part on the back of the speaker cover. The speaker cover is an upgradeable speaker cover, such as Figure 3 As shown, Figure 3 Schematic diagram of the structure of an adjustable reflector. The internal structure of the adjustable reflector may be an umbrella-shaped structure, so that when adjusting the angle, its shape, size or opening degree may be adjusted according to different needs.

[0063] Step S10: Obtain multimedia play instructions.

[0064] It is understandable that the multimedia play instruction may be a music play instruction, a video play instruction, etc., and this embodiment does not limit this. This embodiment is described by taking the music play instruction as an example.

[0065] In a specific implementation, when a user sits in the front row of a vehicle or a user opens the front door of the vehicle but does not sit down for a preset waiting time, the vehicle's liftable speaker cover is controlled to rise, and it is detected whether there is a multimedia playback instruction.

[0066] The multimedia playback instructions can be preset instructions for "music playback" that users manually operate through the "music playback" application or set in advance, such as gesture instructions, voice instructions, etc. Users can customize specific gestures or voices in advance as instructions for automatic music playback.

[0067] Step S20: determining the data to be played according to the multimedia play instruction.

[0068] In a specific implementation, the multimedia play instruction may be analyzed to determine the data to be played, and the data to be played may include the type, name, content, etc. of the data to be played.

[0069] For example, if the multimedia play instruction is a music play instruction, the data to be played includes the type of music to be played, the name of the music to be played, the specific content of the music to be played, etc.

[0070] Step S30: determining a target reflection angle based on the data to be played.

[0071] It should be understood that the optimal reflection angle of the reflection plate under the currently played content can be determined by analyzing the data to be played.

[0072] The target reflection angle may be an angle at which the data to be played is optimally displayed within a certain range of the user's hearing.

[0073] Step S40: adjusting the adjustable reflector according to the target reflection angle to achieve vehicle multimedia playback control.

[0074] In a specific implementation, after the target reflection angle is determined, the adjustable reflector can be controlled to adjust the angle according to the target reflection angle. When the liftable speaker cover is just raised, the angle of the adjustable reflector can be 0 degrees or 90 degrees. After the target reflection angle is determined, the angle of the adjustable reflector can be adjusted to the target reflection angle. For example, if the target reflection angle is 30 degrees, the adjustable reflector is adjusted to 30 degrees. After the angle adjustment is complete, the data to be played is played to complete the vehicle multimedia playback control.

[0075] It should be noted that when adjusting the adjustable reflector, the appropriate hearing range corresponding to the position of the occupant in the vehicle may also be comprehensively considered. Therefore, step S40 may include steps A11 to A13:

[0076] Step A11: Obtain the head range information of the occupant in the vehicle.

[0077] It should be noted that the head range information of the occupants in the vehicle can be pre-stored in the vehicle computer in advance, and when the angle of the reflector needs to be adjusted, the pre-stored head range information of the occupants in the vehicle can be directly read. Specifically, the position information of the occupants in the vehicle can be obtained first, and after determining the specific position of the occupants in the vehicle, the head range information of the occupants in the vehicle can be obtained.

[0078] Step A12: Controlling the adjustable reflector to rotate based on the head range information of the vehicle occupant.

[0079] It is understandable that after determining the head range information of the occupant in the vehicle, the angle at which the adjustable reflector needs to be rotated can be determined based on the head range information of the occupant in the vehicle, thereby controlling the adjustable reflector to rotate.

[0080] Step A13: When the adjustable reflector plate has completed its rotation, the adjustable reflector plate is adjusted to the target reflection angle.

[0081] Specifically, the adjustable reflective plate can be controlled to rotate to within the head range of the vehicle occupant, and after rotating to within the head range of the vehicle occupant, the rotation is completed, and then the adjustable reflective plate is adjusted to the target reflection angle.

[0082] like Figure 4 As shown, Figure 4 This is a schematic diagram of the effect of adjusting the angle of the reflector on the sound reflection angle. The reflector is rotated to within the range of the occupant's head, and the reflection angle of the reflector is adjusted.

[0083] In a feasible implementation manner, after step S40, step S41 may also be included:

[0084] Step S41: after detecting that the angle adjustment of the adjustable reflector is completed, controlling the liftable speaker cover to play multimedia according to the data to be played.

[0085] In a specific implementation, it can be detected in real time whether the angle of the adjustable reflector plate has been adjusted. If not, the adjustable reflector plate will continue to be controlled for adjustment. If the adjustable reflector plate has been adjusted, the liftable speaker cover can be controlled according to the data to be played to perform multimedia playback, such as music or video playback.

[0086] In a specific implementation, it is also possible to detect in real time whether the data to be played has been completed. If the playback is completed or the user switches the playback data, the target reflection angle needs to be re-determined, and the step of determining the data to be played is returned to re-analyze the data to be played, determine the latest reflection angle, and complete the adjustment of the adjustable reflector, and continue multimedia playback after the adjustment is completed.

[0087] This embodiment provides a vehicle multimedia playback control method, which is applied to a speaker cover on a vehicle, wherein the speaker cover is provided with an adjustable reflector opposite to a sound source; the vehicle multimedia playback control method comprises: obtaining a multimedia playback instruction; determining the data to be played according to the multimedia playback instruction; determining a target reflection angle based on the data to be played; and adjusting the adjustable reflector according to the target reflection angle to achieve vehicle multimedia playback control. The angle is flexibly adjusted by the adjustable reflector, and the optimal reflection angle of the adjustable reflector is adjusted based on audio analysis, so that when facing different multimedia playback data, the optimal reflection angle is determined, so that the layering of the sound is highlighted when playing multimedia data, and the user experience is improved.

[0088] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 5 , step S30 includes steps S301 to S302:

[0089] Step S301: performing audio band analysis on the data to be played to obtain audio band data.

[0090] It should be noted that the data to be played can be pre-read, so as to perform audio band analysis on the data to be played to obtain audio band data.

[0091] It can be understood that the audio band data is the audio data at each reflection angle in the data to be played and the corresponding decibel data, etc.

[0092] Step S302: determining a target reflection angle based on the audio band data.

[0093] In a specific implementation, the target reflection angle may be determined according to the audio band data. For example, the audio band data with different reflection angles may be screened to obtain the reflection angle corresponding to the audio band data with the best performance, and use it as the target reflection angle.

[0094] In a feasible implementation, step S302 may include steps B11 to B13:

[0095] Step B11: determining the sound range frequency decibel curve corresponding to different reflection angles based on the audio band data.

[0096] It is understandable that the sound range frequency decibel curves under different reflection angles can be predicted based on the audio band data analysis, and the same audio band data may have different corresponding curves under different reflection angles.

[0097] Step B12: Obtain a preset audio range.

[0098] It should be noted that the preset audio range is the range in which human hearing is most sensitive, specifically, it may be in the range of 2kHz to 5kHz. The preset audio range may be determined in advance, and when angle adjustment is required, the preset audio range may be read.

[0099] Step B13: determining a target reflection angle based on the preset audio range and the sound range frequency decibel curve.

[0100] In a specific implementation, the changes of different curves in the preset audio range can be determined in the sound range frequency decibel curve according to the preset audio range of 2kHz to 5kHz, so as to determine the optimal reflection angle among different reflection angles.

[0101] In a feasible implementation, step B13 may include: searching for a target sound range frequency decibel curve that meets preset requirements in the sound range frequency decibel curve based on the preset audio range; and using the reflection angle corresponding to the target sound range frequency decibel curve as the target reflection angle.

[0102] It should be noted that the target sound range frequency decibel curve of the preset requirement is the sound range frequency decibel curve with the least obvious drop in decibel value. For example, the sound range frequency decibel curve includes curve 1, curve 2 and curve 3. Within the preset audio range, the curve with the least obvious drop in decibel value is curve 2, then the target sound range frequency decibel curve is curve 2, and the reflection angle corresponding to curve 2 is used as the target reflection angle.

[0103] like Figure 6 As shown, Figure 6The decibel curves of the sound range frequency of the data to be played at different reflection angles include flat placement without a deflector, 60° deflector (reflection angle of 60°), 45° deflector (reflection angle of 45°), 30° deflector (reflection angle of 30°), 90° deflector (reflection angle of 90°) and upright placement. The decibel curves of the sound range frequency corresponding to different angles vary differently.

[0104] It can be analyzed that in the range of 2kHz to 5kHz, the 30-degree refraction plate has the least obvious drop in decibel value, so the target reflection angle is 30 degrees.

[0105] This embodiment obtains audio band data by performing audio band analysis on the data to be played, and determines the target reflection angle based on the audio band data. By analyzing the audio band, specific frequency components in the audio signal can be identified and optimized, thereby improving the sound quality. The most suitable reflection angle among the reflection angles of different reflectors can be quickly determined based on the specific frequency, thereby improving the accuracy of adjustment.

[0106] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 7 , step S30 includes steps S301' to S303':

[0107] Step S301': Determine whether the data to be played is data to be played for the first time.

[0108] It should be noted that before adjusting the angle, in order to improve the efficiency of the adjustment, it is possible to first determine whether the data to be played is the first time to play the data. If it is the first time to play the data, the data to be played can be analyzed to determine the optimal reflection angle. After the playback is completed, the played data and the corresponding parameters of the target reflection angle can also be stored in the vehicle computer to facilitate the next call.

[0109] Step S302': when the data to be played is not the first-time played data, historical play information is called.

[0110] In the specific implementation, if the data to be played is not the first time to be played, it proves that the corresponding data has been played before, and the corresponding reflection angle will also be stored. The saved historical playback information can be directly called. The historical playback information includes detailed information of the data to be played and the adjustment angle of the corresponding reflector.

[0111] Step S303 ′: searching the historical playback information for a historical reflection angle corresponding to the data to be played according to the data to be played, and using the historical reflection angle as a target reflection angle.

[0112] It is understandable that the corresponding historical reflection angle can be queried in the historical playback information according to the data to be played, so as to be used as the target reflection angle.

[0113] This embodiment determines whether the data to be played is the first time to be played; if the data to be played is not the first time to be played, the historical play information is called; according to the data to be played, the historical reflection angle corresponding to the data to be played is searched in the historical play information, and the historical reflection angle is used as the target reflection angle. By determining whether there is a play record of the data to be played, the target reflection angle can be quickly determined according to the stored parameters, thereby improving the efficiency of determining the reflection angle.

[0114] For example, in order to help understand the implementation process of the vehicle multimedia playback control method obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 8 , Figure 8A brief flow chart of a vehicle multimedia playback control method is provided. Specifically, when a user sits in the front row of the vehicle, a seat sensor detects, or the user opens the front door without sitting down, and waits for a preset time, such as 6 seconds, the vehicle IBCM (Integrated Body Control Module) controls the lifting horn to rise, and detects whether there is a playback instruction through the interaction interface of the vehicle DA (Driver Assistance), such as the user manually operates through a "music playback" APP or a preset "music automatic playback" instruction. When the instruction is detected, the vehicle CDC (Continuous Damping Control) determines whether the data to be played is the first time the music is played. If there is already a playback record of the music, the vehicle CDC calls the corresponding parameters that have been saved, and at the same time the DMS (Driver Monitoring System) and OMS (Occupancy Monitoring System) in the vehicle System, passenger monitoring system) captures the position of the driver's head and the front passenger's head to obtain the range information of the occupant's head; performs calculations according to the preset program: 1. Reads the pre-stored occupant's head range information; 2. Inputs the optimal reflection angle information obtained from the previous step of analysis; 3. Calculates the required rotation angle of the reflector and ensures that the angle covers the range of the occupant's head; If it is the first time to play music, the entire CDC audio song is pre-read, and the audio band analysis is performed through the CDC of the whole vehicle: the audio is read, the sound range frequency decibel curve of different reflection angles is analyzed and predicted, and the reflection angle with the best performance (the least obvious decrease in decibel value) within 2kHz to 5kHz (the most sensitive range of human hearing) is determined, and the calculation is performed according to the preset program. The CDC of the whole vehicle outputs the required rotation angle of the above-mentioned reflector and sends it to the IBCM of the whole vehicle. The IBCM of the whole vehicle controls the actuation of the reflector of the lifting speaker to adjust the angle. After the adjustment, the current music is played through the speaker. After the music is played to the next song, it returns to the above-mentioned step of analyzing the music data to determine the angle.

[0115] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the vehicle multimedia playback control method of the present application.
