[0052] The present application is described below based on embodiments, but the present application is not limited to these embodiments. In the detailed description of the present application below, some specific details are described in detail. It is possible for those skilled in the art to fully understand the present application without the description of these details. In order to avoid confusing the essence of the present application, known methods, processes, flows, components and circuits are not described in detail.

[0053] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0054] At the same time, it should be understood that in the following description, "circuit" refers to a conductive loop composed of at least one element or subcircuit through electrical connection or electromagnetic connection. When an element or circuit is said to be "connected to" another element or an element / circuit is said to be "connected between" two nodes, it can be directly coupled or connected to another element or there can be an intermediate element. The connection between the elements can be physical, logical, or a combination thereof. Conversely, when an element is said to be "directly coupled to" or "directly connected to" another element, it means that there is no intermediate element between the two.

[0055] Unless the context clearly requires otherwise, the words "include", "comprising" and the like throughout this application should be interpreted as including rather than exclusive or exhaustive; that is, as meaning "including but not limited to".

[0056] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, "multiple" means two or more. In addition, the schemes described in this specification and the embodiments, if involving the processing of personal information, will be processed on the premise of having a legal basis (for example, with the consent of the subject of personal information, or necessary for the performance of a contract, etc.), and will only be processed within the prescribed or agreed scope. The user's refusal to process personal information other than the necessary information required for basic functions will not affect the user's use of basic functions.

[0057] At present, in some specific scenarios, multiple audio playback devices are often set up to meet the needs of the specific scenario. For example, in the scenario of a vehicle cockpit, multiple audio playback devices are set up in the vehicle cockpit to meet the needs of dual-source playback. For another example, in a conference scenario, an audio playback device can be set up near each seat or near multiple adjacent seats in advance so that all participants can hear the corresponding audio content clearly.

[0058] However, if there are users or areas with specific needs such as silence, low volume or personalization in the above-mentioned scenes, the relevant technology will not be able to guarantee the specific needs, so that the scenes of multiple audio playback devices have certain defects. For example, when the driver is driving the vehicle, he often needs to concentrate. At this time, the audio (such as songs and other audio) played in the vehicle cockpit other than the navigation audio will distract the driver's attention to a certain extent, thereby causing certain safety hazards. Correspondingly, the navigation audio listened to by the driver will also cause certain interference to the passengers in the vehicle cockpit (for example, the navigation audio will interfere with the passengers listening to songs to a certain extent). That is to say, in this case, the driver and the passenger (or the area where the driver and the passenger are located) have specific needs such as silence, low volume or personalization in the scene of the vehicle cockpit, but the relevant technology cannot currently meet the specific needs. For another example, if only some people participate in a meeting or class in a venue, the people or areas other than the participants are users or areas with specific needs such as silence, low volume or personalization, but the relevant technology cannot currently meet the specific needs.

[0059] Therefore, how to meet specific requirements such as silence, low volume or personalization in a scene is an urgent problem that needs to be solved.

[0060] In order to solve the above problems, the embodiment of the present application provides an audio playback control method to play the target audio data in one or more areas and not play the target audio data in other areas, so as to meet specific requirements such as mute, low volume or personalization. Among them, the audio playback control method of the embodiment of the present application can be applied to a control device, the control device can be a terminal or a server, the terminal can be a smart phone, a tablet computer, a vehicle control terminal or a personal computer (PC), etc., and the server can be a single server, a server cluster configured in a distributed manner, or a cloud server.

[0061] like Figure 1 As shown, the audio playback control method of the embodiment of the present application may include the following steps:

[0062] In step S100, target audio data of multiple audio sources are determined.

[0063] The target audio data of each sound source may be provided to one or a group of audio playback devices for playback, that is, the target audio data of each sound source may correspond to one or more audio playback devices.

[0064] In an optional embodiment, if Figure 2 As shown, the above step S100 may include the following steps:

[0065] In step S110, at least one original audio data is acquired.

[0066] The original audio data may be one or more of multimedia audio data (such as music, etc.), navigation audio data, call audio data, conference voice data or other applicable audio data.

[0067] In step S120, upmix processing is performed on each original audio data to determine target audio data of multiple audio sources.

[0068] Specifically, the embodiment of the present application can perform upmixing processing on each original audio data based on an upmixing algorithm, wherein the upmixing algorithm refers to an algorithm that expands the sound source of the audio data input by the front end into more output sound sources.

[0069] It should be noted that if the number of original audio data obtained by the embodiment of the present application is greater than 1, the embodiment of the present application needs to perform upmixing processing on each original audio data separately to determine the multi-source target audio data corresponding to each original audio data. The embodiment of the present application can effectively expand the number of audio sources of audio data through upmixing processing, so that the target audio data of each audio source can be used separately for one or a group of audio playback devices, thereby improving the controllability of the audio playback device in a single scene, and further meeting specific needs such as mute, low volume or personalization in the scene.

[0070] In step S200, a control interface is displayed.

[0071] Among them, the control device of the embodiment of the present application can display the control interface through the display unit set by itself, and can also display the control interface through an external display device (such as an external display screen or other display device). The control interface includes at least a plurality of adjustment controls corresponding to predetermined areas, each predetermined area corresponds to at least one audio playback device, and the target audio data of each sound source corresponds to one or more audio playback devices. The user can trigger the adjustment controls displayed in the control interface by touch control, voice control or external devices (such as external devices such as a mouse or keyboard).

[0072] That is to say, the embodiment of the present application can divide a certain scene (vehicle cabin scene, meeting scene or classroom scene, etc.) into multiple predetermined areas, and control whether the audio playback device in each predetermined area plays audio, as well as the audio content played (i.e., target audio data) through a control interface.

[0073] Take the vehicle cockpit scene as an example. Figure 3 As shown, in one case, if the number of target audio data of the multi-source is 1 ( Figure 3Taking navigation audio as an example), in the navigation audio control interface 31 corresponding to the navigation audio, the user can press and hold the vehicle adjustment control 311 and move it toward the upper left corner (for example Figure 3 The main driving adjustment control 312 is triggered (i.e., selected) by sliding the main driving adjustment control 312 in the upper left corner. Accordingly, the navigation audio is played in the predetermined area (i.e., the main driving area) corresponding to the main driving adjustment control 312. Figure 3 The filled adjustment control represents the triggered adjustment control.

[0074] In addition, if the user wishes to deselect the main driver adjustment control 312, the user may press and hold the whole vehicle adjustment control 311 again and slide it toward the upper left corner to deselect the main driver adjustment control 312. If the user wishes to play the navigation audio in all audio players in the vehicle cockpit, the user may click to select the whole vehicle adjustment control 311 to play the navigation audio in all audio players in the vehicle cockpit.

[0075] In another case, if the number of target audio data of multiple audio sources is greater than 1, the embodiment of the present application can set adjustment controls for each category of target audio data. Figure 4 As shown, in the embodiment of the present application, corresponding adjustment controls are respectively set for media audio data, call audio data and navigation audio data in the control interface 41. The user can trigger the adjustment controls by clicking or the like to make the corresponding audio data play in the corresponding predetermined area.

[0076] In another case, if the number of target audio data of multiple audio sources is greater than 1, the embodiment of the present application can also set each adjustment control in a multi-level manner. Figure 5 As shown, in the embodiment of the present application, adjustment controls for jumping are respectively set for media audio data, call audio data and navigation audio data in the control interface 51. When the user triggers the adjustment control for jumping by clicking or the like, the control interface 51 can jump to the corresponding interface. Figure 5 As shown, if the user triggers the adjustment control for jumping corresponding to the navigation audio data, the embodiment of the present application can control the display interface to jump to the navigation audio control interface 31, so that the user can further choose to trigger the adjustment control corresponding to each predetermined area.

[0077] Need to explain, Figure 3 , Figure 4 and Figure 5 This is only an example of the embodiment of the present application. The embodiment of the present application does not limit the use scenario of the control interface, the user interface design (UI) and the triggering method of the adjustment control. Figure 3For example, the various adjustment controls in the navigation audio control interface 31 can adopt other UI designs, and the user can also trigger the various adjustment controls in the navigation audio control interface 31 by clicking or voice control.

[0078] In addition, the control interface of the embodiment of the present application can also be applied to other applicable scenarios such as conferences and classrooms. For example, in a conference scenario, the embodiment of the present application can set a control device in the conference venue to display the control interface, and further, the user can trigger the adjustment control displayed by the control device to make the target audio data play in the corresponding area.

[0079] In step S300, in response to at least one adjustment control being triggered, each audio playback device is controlled so that the target audio data is played in a predetermined area corresponding to the triggered adjustment control.

[0080] Among them, the audio playback device can be a speaker, a speaker or other device. The embodiment of the present application can control each audio playback device through a mute interface (mute) or an audio adjustment algorithm, so that the target audio data can be played in a predetermined area selected by the user.

[0081] The embodiment of the present application can determine the target audio data of multiple audio sources and display a control interface to the user for the user to select one or more predetermined areas. When the user chooses to trigger the adjustment control corresponding to one or more predetermined areas, the embodiment of the present application can control each audio playback device so that the target audio data is played in the predetermined area corresponding to the triggered adjustment control. In this way, when there are multiple audio playback requirements in a scene, the embodiment of the present application can meet the specific requirements of mute, low volume or personalization of different predetermined areas through the control interface and the target audio data of multiple audio sources.

[0082] In an optional implementation, the embodiment of the present application can control each audio playback device through a mute interface. Figure 6 As shown, the above step S300 may include the following steps:

[0083] In step S310, the target playback device corresponding to the triggered adjustment control is determined.

[0084] The target playback device is used to represent the audio playback device selected from the various audio playback devices. Since there is a corresponding relationship between the adjustment control and the predetermined area, when the adjustment control is triggered, the embodiment of the present application can determine the various target playback devices in the predetermined area according to the predetermined area corresponding to the triggered adjustment control.

[0085] In step S320, the target playback device is controlled to play the target audio data through the mute interface corresponding to each audio playback device.

[0086] Among them, the mute interface is an interface for controlling whether the audio playback device is mute, which can be set in an audio processing chip (Digital Signal Processing, DSP). Through the mute interface, the embodiment of the present application can set the devices other than the target playback device in each audio playback device to be mute, so as to achieve the target audio data being played only in the predetermined area where the target playback device is located, and to achieve specific requirements such as playing other audio, mute or low volume in other predetermined areas.

[0087] In an optional implementation, the embodiment of the present application can also control each audio playback device through an audio adjustment algorithm. Specifically, the above step S300 can also be performed as follows: adjusting the strength and balance of the target audio data through a preset audio adjustment algorithm so that the target audio data is played in a predetermined area corresponding to the triggered adjustment control.

[0088] Among them, the audio adjustment algorithm of the embodiment of the present application may include at least an audio fade algorithm and / or an audio balance adjustment algorithm. The audio fade algorithm can be used to adjust the volume of the target audio data between each audio playback device, and the audio balance adjustment algorithm can be used to adjust the balance of the target audio data between each audio playback device. Therefore, through the audio adjustment algorithm, the embodiment of the present application can adjust the strength and balance of the target audio data of each audio playback device according to the triggered target playback device, so that the target audio data is played in the predetermined area corresponding to the triggered adjustment control, and the specific needs of mute, low volume or personalization of different predetermined areas are met respectively.

[0089] According to the above implementation, it can be seen that the audio playback control method provided in the embodiment of the present application can be applied to a variety of scenarios, thereby meeting the specific needs of each scenario such as mute, low volume or personalization.

[0090] Based on the same technical concept, the embodiment of the present application also provides a control device, such as Figure 7 As shown, the control device 71 at least includes a control unit 711, an audio processing chip 712 and a display unit 713, wherein the control unit 711 can be connected to the audio processing chip 712 and the display unit 713, and is configured to control the display unit 713 and the audio processing chip 712. In addition, the control device 71 can be connected to each audio playback device 72 in the vehicle through a controller area network bus (Controller Area Network, CAN), so as to control each audio playback device 72 through the audio processing chip 712.

[0091] In the control device 71, the display unit 713 is configured as a controlled display control interface.

[0092] The control interface at least includes adjustment controls corresponding to a plurality of predetermined areas, and each predetermined area corresponds to at least one audio playback device 72. Specifically, the control interface displayed by the display unit 713 may be as follows: Figure 3 , Figure 4 or Figure 5 The control interface shown may also be other applicable control interfaces.

[0093] The audio processing chip 712 is configured to control and determine the target audio data of the multiple audio sources, and in response to at least one adjustment control being triggered, control each audio playback device 72 so that the target audio data is played in a predetermined area corresponding to the triggered adjustment control. The target audio data of each audio source corresponds to one or more audio playback devices 72 respectively.

[0094] The control device of the embodiment of the present application can determine the target audio data of multiple audio sources and display the control interface to the user for the user to select one or more predetermined areas. When the user chooses to trigger the adjustment control corresponding to one or more predetermined areas, the control device of the embodiment of the present application can control each audio playback device so that the target audio data is played in the predetermined area corresponding to the triggered adjustment control. In this way, when there are multiple audio playback requirements in the vehicle cockpit scene, the embodiment of the present application can meet the specific requirements of mute, low volume or personalization of different predetermined areas through the control interface and the target audio data of multiple audio sources.

[0095] by Figure 4 For example, for target audio data of the media type, the user can choose to trigger the front passenger seat, rear left and rear right in the control interface 41 to prevent the driver from being affected by the media audio data while driving the vehicle, thereby improving the safety of driving the vehicle.

[0096] In an optional implementation, the audio processing chip may also be configured to obtain at least one original audio data, perform upmixing processing on each original audio data, and determine target audio data of multiple audio sources.

[0097] The original audio data may be one or more of multimedia audio data (such as music, etc.), navigation audio data, call audio data, conference voice data, or other applicable audio data. The embodiment of the present application may perform upmixing processing on each original audio data based on an upmixing algorithm, wherein the upmixing algorithm refers to an algorithm for expanding the sound source of the audio data input by the front end into more output sound sources.

[0098] The embodiment of the present application can effectively expand the number of audio sources of audio data through upmixing processing, so that the target audio data of each audio source can be used separately for one or a group of audio playback devices, thereby improving the controllability of the audio playback device in a single scene, and further meeting specific needs such as muteness, low volume or personalization in the scene.

[0099] In an optional implementation, the audio processing chip may include a mute interface, wherein the mute interface is an interface for controlling whether the audio playback device is muted. Further, the audio processing chip may also be configured to control the target playback device corresponding to the triggered adjustment control, and control the target playback device to play the target audio data through the mute interface corresponding to each audio playback device.

[0100] like Figure 8 As shown, the audio processing chip 712 may include multiple mute interfaces, each of which may be used to control whether one or more audio playback devices are muted. In the process of audio playback control, the control unit 711 may input at least one original audio data into the audio processing chip 712 through a time-division multiplexing (TDM) channel, and the audio processing chip 712 may first perform a control operation on each original audio data (e.g. Figure 8 The audio processing chip 712 performs upmixing processing on the original audio data (including original audio data of types such as media, navigation, calls, and notifications) to determine the multi-source target audio data corresponding to each original audio data. Further, after the user selects to trigger at least one adjustment control through the control interface, the audio processing chip 712 can mute the devices other than the target playback device in each audio playback device through each mute interface.

[0101] Furthermore, after the target audio data is processed by the mute interface, the audio processing chip 712 can mix the target audio data of various types, and output the mixed target audio data to the Accelerated Massive Parallelism (AMP) unit 81 through the time division multiplexing channel, so that the parallel computing unit 81 can control the audio playback devices 72 in parallel. Therefore, through the mute interface set in the audio processing chip 712, the audio processing chip 712 can set the devices other than the target playback device in the audio playback devices to be mute, so as to achieve the target audio data being played only in the predetermined area where the target playback device is located, and to achieve specific requirements such as playing other audio, mute or low volume in other predetermined areas.

[0102] In an optional implementation, the audio processing chip can also control each audio playback device through an audio adjustment algorithm. Specifically, the audio processing chip can also be configured to adjust the strength and balance of the target audio data through a preset audio adjustment algorithm so that the target audio data is played in a predetermined area corresponding to the triggered adjustment control.

[0103] The audio adjustment algorithm of the embodiment of the present application may include at least an audio fade algorithm and / or an audio balance adjustment algorithm. The audio fade algorithm may be used to adjust the volume of the target audio data between various audio playback devices, and the audio balance adjustment algorithm may be used to adjust the balance of the target audio data between various audio playback devices.

[0104] like Fig. 9 As shown, during the audio playback control process, the control unit 711 can input at least one original audio data into the audio processing chip 712 through a time division multiplexing channel, and the audio processing chip 712 can first process each original audio data (for example Fig. 9 The audio processing chip 712 performs upmixing processing on the original audio data (including original audio data of media, navigation, call, and notification types) to determine the multi-source target audio data corresponding to each original audio data. Further, after the user selects to trigger at least one adjustment control through the control interface, the audio processing chip 712 can adjust the strength and balance of the target audio data through the audio adjustment algorithm.

[0105] Furthermore, after the target audio data is processed by the audio adjustment algorithm, the audio processing chip 712 can mix the target audio data of various types, and output the mixed target audio data to the parallel computing unit 81 through the time division multiplexing channel, so that the parallel computing unit 81 controls the audio playback devices 72 in parallel. Therefore, the audio processing chip 712 can adjust the strength and balance of the target audio data of each audio playback device according to the triggered target playback device through the audio adjustment algorithm, so that the target audio data is played in the predetermined area corresponding to the triggered adjustment control, respectively meeting the specific requirements of mute, low volume or personalization of different predetermined areas.

[0106] Based on the same technical concept, the embodiment of the present application provides a vehicle for a vehicle cabin scenario, wherein the vehicle at least includes the above-mentioned control device (for example Figure 7 The control device 71 shown in the figure) and at least one audio playback device. It should be noted that the control device of the embodiment of the present application can be installed in the vehicle as a vehicle control terminal and connected to other devices in the vehicle through a controller area network bus to control other devices.

[0107] For example, Fig.10As shown, the vehicle 1001 may include a control device 71 and at least one audio player 72. The control device 71 may be connected to each audio player 72 in the vehicle via a controller area network bus, so as to control each audio player 72 via an audio processing chip.

[0108] Specifically, the control device 71 in the vehicle 1001 can determine the target audio data of multiple sound sources and display the control interface to the user for the user to select one or more predetermined areas. When the user chooses to trigger the adjustment control corresponding to one or more predetermined areas, the control device 71 can control each audio playback device so that the target audio data is played in the predetermined area corresponding to the triggered adjustment control. In this way, when there are multiple audio playback requirements in the cockpit of the vehicle 1001, the embodiment of the present application can meet the specific requirements of mute, low volume or personalization of different predetermined areas through the control interface and the target audio data of multiple sound sources.

[0109] In an optional implementation, the vehicle of the embodiment of the present application includes at least a main driving area and a co-pilot area, wherein the main driving area and the co-pilot area each include at least one audio playback device.

[0110] Furthermore, the driver or passenger can control at least the audio playback devices in the main driving area and the co-pilot area through a control device (i.e., a vehicle control terminal) provided in the vehicle to meet specific requirements of different predetermined areas such as mute, low volume, or personalization.
