All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the existing vehicle-mounted entertainment system, a single-tone area system is often adopted for multimedia playing, so that the whole vehicle can only play the same sound source at the same time. The invention adopts a multi-sound zone audio playing management method, so that each driver and passengers can enjoy independent sound field space and enjoy respective audio and video entertainment contents, thereby improving the entertainment experience of users.

Referring to fig. 1, fig. 1 is an architecture diagram of a system for managing playing of multi-zone audio according to an embodiment of the present invention, as shown in fig. 1, the architecture diagram includes an audio channel 110 and an audio channel 130 connected to an electronic device 100, where the audio channel 110 is divided into a zone 1, the audio channel 130 is divided into a zone 2, the zone 1 is provided with a policy database 120, and the zone 2 is provided with a policy database 140.

The electronic apparatus 100 divides the plurality of audio channels into a plurality of sound zones according to the positions of the audio channels in the vehicle and independently plays audio in each sound zone, for example, the plurality of audio channels 110 on the main driving side may be divided into sound zone 1. In particular, the soundfield may include one or more of a main driving zone, a secondary driving zone, and a rear row soundfield. Therefore, each driver and passengers in the vehicle have independent sound zone to play audio, and the entertainment experience of users is improved.

In addition, the electronic device 100 may configure the policy database 120 for the sound zone 1, specifically, when a plurality of sound sources request to play simultaneously, the electronic device 100 may configure an audio focus for a high-priority sound source according to the management policy in the policy database 120, for example, when a call is dialed, the electronic device 100 queries the management policy in the policy database 120 to determine that the priority of the call audio is higher, and the electronic device 100 configures an audio focus for the call sound source to play the audio through the corresponding audio channel 110 corresponding to the sound zone 1. Therefore, the audio can be accurately played in different sound field spaces, and the user experience is optimized.

The following describes a method for managing playing of multi-zone audio according to an embodiment of the present invention with reference to fig. 2.

The method for managing the multi-audio-zone audio playing provided by the embodiment of the invention is applied to electronic equipment.

As shown in fig. 2, the flowchart includes S210-S250 according to the method for managing playing of multi-zone audio, and the following steps are described in detail:

s210, the electronic equipment divides the audio channel into a plurality of sound zones according to the position of the audio channel.

Specifically, a plurality of audio channels are provided in the vehicle, the audio channels may be one or more of a speaker, a bluetooth headset, an audio headrest, and the like, and the electronic device divides the audio channels into a plurality of sound zones according to the positions of the audio channels, for example, the plurality of audio channels on the main driving side may be divided into main driving sound zones. In particular, the soundfield may include one or more of a main driving zone, a secondary driving zone, and a rear row soundfield. Therefore, each driver and passengers in the vehicle have independent sound zone to play audio, and the entertainment experience of users is improved.

S220, the electronic equipment configures a strategy database for each sound zone.

Specifically, the policy database is used for storing management policies required by the electronic device for focus arbitration, and more specifically, the management policies in the policy database may be customized according to the location of the sound zone, for example, in the main driving sound zone, the navigation prompt sound has a higher priority than other sound sources, and when the navigation application needs to play the navigation prompt sound, the main driving sound zone may play the navigation prompt sound preferentially. And if other sound zones do not need to be driven, the navigation prompt sound can be forbidden in the management strategy of the corresponding sound zone. Therefore, the sound source priority management strategy with flexible sound zones is more in line with the use habits of users.

And S230, the electronic equipment receives the audio playing request of the target sound zone and judges whether an audio focus is configured for the audio playing request according to the strategy database.

Specifically, the electronic device may configure an audio focus for the high-priority sound source according to a management policy in the policy database, and more specifically, the electronic device may receive an audio play request from the target sound zone, respond to the audio play request, obtain a management policy corresponding to the audio requested to be played from the policy database corresponding to the target sound zone, and determine whether to configure the audio focus for the audio requested to be played according to the management policy, where the audio play request includes a sound zone identifier of the audio requested to be played and a sound source type of the audio requested to be played. Therefore, the audio can be accurately played in different sound field spaces, and the user experience is optimized.

More specifically, the electronic device queries a current playlist of the target sound zone and a policy database corresponding to the sound zone identifier based on the sound zone identifier of the target sound zone, and arbitrates the configuration of the audio focus according to the management policy in the policy database, the sound source type of the audio currently being played in the current playlist, and the sound source type of the audio requested to be played, so as to determine whether to configure the audio focus for the audio requested to be played. The sound source type comprises one of online music, local music, conversation audio and prompt tone. When the current playing list has audio which is being played, the electronic equipment configures an audio focus for the audio with the sound source type with the highest priority according to the priority of the sound source type in the strategy database; and when no audio which is being played exists in the current playlist, the electronic equipment directly configures an audio focus for the audio which is requested to be played according to the management strategy. Therefore, each sound zone can obtain independent audio playing experience by performing audio focus arbitration on each sound zone respectively.

S240, when the audio focus is determined to be configured for the audio requested to be played, the electronic equipment plays the audio requested to be played through the audio channel corresponding to the target sound zone.

Specifically, the electronic device updates the corresponding playlist of the target soundtrack and pauses playing the current audio. Then, the electronic device informs the multimedia program to obtain the audio focus, and the multimedia program plays the audio requested to be played through the audio channel corresponding to the target sound zone.

And S250, when the electronic equipment determines that the audio focus can not be configured for the audio requested to be played, maintaining the current playing state of the sound zone.
