[0030] In a vehicle, an audio playback application used on a display screen usually plays audio through an audio playback device provided in the vehicle. For example, an audio playback application used on the main driver's display screen plays audio through a speaker provided in the vehicle, and an audio playback application used on the co-driver's display screen plays audio through a Bluetooth headset provided in the vehicle. With the increase in in-vehicle display screens, such as the overhead display screen in the back row and the seat-back display screen in the back row, since multiple display screens all have audio playback requirements, there has emerged a problem of adapting multiple audio playback devices to multiple display screens. Therefore, how to better implement the audio playback of audio playback applications used on different display screens is an urgent problem to be solved currently.

[0031] To solve the above technical problems, the present application proposes an audio playback method, which is applied to a vehicle. The vehicle includes multiple display screens and multiple audio playback devices, and the multiple audio playback devices include an in-vehicle audio system, an out-of-vehicle audio system, and headphones. In this audio playback method, the display screen is bound to the audio playback device. When an audio playback instruction is received, the target display screen is determined based on the target audio playback application, and the target audio playback device is determined based on the target display screen. When the target audio playback application has the audio playback permission, the target audio playback application plays the corresponding audio through the target audio playback device, so as to realize the audio playback of the audio playback applications on different display screens. Through this method, the target display screen, the target audio playback device corresponding to the target audio playback application, and the audio playback permission of the target audio playback application can be determined, so that the audio playback of the audio playback applications used on different display screens can be better realized, thereby improving the user experience.

[0032] Reference Figure 1 , Figure 1 FIG. is a schematic flowchart of an audio playback method disclosed in an embodiment of the present invention. In an embodiment of the present invention, the method includes the following steps.

[0033] Step S1, in response to receiving an audio playback instruction for a target audio playback application, determine the target display screen corresponding to the target audio playback application.

[0034] Step S2, according to the binding relationship between the display screen and the audio playback device, determine the target audio playback device bound to the target display screen.

[0035] Step S3, when it is determined that the target audio playback application has the audio playback permission according to the target audio playback device, enable the target audio playback application to play the corresponding audio through the target audio playback device.

[0036] When the above audio playback method is adopted, when an audio playback instruction is received, the target audio playback device bound to the target display screen can be determined based on the target display screen corresponding to the target audio playback application. When it is determined that the target audio playback application has the audio playback permission according to the target audio playback device, enable the target audio playback application to play the corresponding audio through the target audio playback device. Through this method, the target display screen, the target audio playback device corresponding to the target audio playback application, and the audio playback permission of the target audio playback application can be determined, so that the audio playback of the audio playback applications used on different display screens can be better realized, thereby improving the user experience.

[0037] The audio playback method disclosed in the embodiments of the present invention is applied to a vehicle. Specifically, the audio playback method is applied to the audio playback system in the vehicle.

Among them, the multiple display screens may include a vehicle head unit central control display screen, a co-pilot display screen, a rear row display screen, etc., and the multiple audio playback devices may include in-vehicle speakers, out-of-vehicle speakers, and headphones, etc. Further, the in-vehicle speakers may include in-vehicle speakers and in-vehicle headrests equipped with speakers, and the headphones include Bluetooth headphones and wired headphones. In addition, the number of in-vehicle speakers, out-of-vehicle speakers, and headphones in the vehicle can be set to multiple respectively.

[0038] In the audio playback method disclosed in the embodiments of the present invention, it is necessary to pre-bind the display screen and the audio playback device.

[0039] Reference Figure 2 , Figure 2 is a schematic diagram of the binding relationship between a display screen and an audio playback device in a vehicle in an audio playback method disclosed in an embodiment of the present invention. In the audio playback method disclosed in the embodiments of the present invention, the in-vehicle speakers can be divided into a first zone of speakers and a second zone of speakers based on the area, and the first zone of speakers can be used as the default audio playback device. The default audio playback device is not bound to the display screen, and the audio playback applications on all the display screens in the vehicle can select to play audio through the default audio playback device. Further, the first zone of speakers can be a group of speakers marked as in-vehicle 1, and the second zone of speakers can be a group of speakers marked as in-vehicle 2. The multiple headphones may include: a first headphone and a second headphone. Further, the first headphone can be Bluetooth headphone 1, and the second headphone can be Bluetooth headphone 2. Further, the binding of the display screen and the audio playback device may include: the central control display screen is bound to the second zone of speakers, the co-pilot display screen is bound to the first headphone, and the rear row screen is bound to the second headphone, where the central control display screen can be the central control screen, the co-pilot display screen can be the co-pilot screen, and the rear row display screen can be the rear row screen.

[0040] Further, the display screen and the audio playback device can be bound one-to-one, or one display screen can be bound to multiple audio playback devices, which is not limited herein, and the user can perform the binding based on specific requirements.

[0041] Further, the specific steps of step S1 include: when the user performs a triggering operation on the display screen or inputs a voice command for audio playback of the target audio playback application, the audio playback system generates an audio playback instruction for the target audio playback application based on the triggering operation or the voice command for audio playback of the target audio playback application. In response to the received audio playback instruction for the target audio playback application, the audio playback system determines the target display screen corresponding to the target audio playback application based on the correspondence between the audio playback application and the display screen. This audio playback instruction is used to instruct the target audio playback application to play the target audio. The specific steps of step S2 include: based on the pre-set binding relationship between the display screen and the audio playback device and the determined target display screen, determining the target audio playback device bound to the target display screen.

[0042] Further, the specific steps of the audio playback method disclosed in the embodiment of the present invention further include: before playing the audio corresponding to the target audio playback application through the target audio playback device, determining whether the target audio playback application has the audio playback permission according to the target audio playback device. If the target audio playback application has the audio playback permission, step S3 is executed; if the target audio playback application does not have the audio playback permission, the audio corresponding to the target audio playback application is played through the default audio playback device pre-set in the vehicle.

[0043] The audio playback method disclosed in the embodiment of the present invention further includes: determining whether the target audio playback application has the audio playback permission according to whether the target audio playback device can obtain the audio focus.
