The audio playing mode of the present application will be described in detail as follows:

referring to fig. 1 and 2, an embodiment of the present application provides an audio playing mode, where the audio playing mode includes:

step 011: and acquiring the audio information to be played.

Specifically, the vehicle is generally provided with a plurality of Application programs (APP), some APP can play audio in the vehicle through a speaker, the vehicle can receive audio information to be played in real time in the using process, play or pause the audio according to the received audio information, and the user can also select which audio to play independently and issue corresponding playing characterization instructions to the vehicle to control the audio to play or pause. When a vehicle acquires audio information to be played, which is transmitted by a plurality of APP, audio collision occurs. The audio types that need to be played by the APP are often different, and different audio types are generally correspondingly provided with different channels. For example, music, video and other APP are correspondingly provided with a multimedia sound channel; the navigation APP plays the navigation voice audio type and is correspondingly provided with a navigation sound channel; the relevant audio of the system is correspondingly provided with system channels.

Optionally, the audio information includes an audio type, and after the audio information to be played is acquired, a preset channel corresponding to each audio type in the audio information is determined based on a preset mapping relationship between the audio type and the preset channel.

Specifically, the audio types and the preset channels may be in one-to-one correspondence, and a preset mapping table representing a mapping relationship between the audio types and the preset channels may be generated, the preset channel table may be stored in at least one of the memory 40 or the server 200, and after the audio information to be played is acquired, the preset channels corresponding to the audio of each audio type in the audio information may be found through the preset mapping table of the audio types and the preset channels, so as to determine the preset channels required for playing the audio information.

For example, if the acquired audio information to be played includes multimedia audio and navigation audio. Then the audio information can be determined to contain the audio of the multimedia channel and the audio of the navigation channel by finding the multimedia channel corresponding to the multimedia audio and the navigation channel corresponding to the navigation audio through the preset mapping relation between the audio type and the preset channel.

Step 012: and carrying out sound reduction processing on the audio of the target channel in the plurality of preset channels under the condition that the audio information comprises the audio of the plurality of preset channels, so that the playing parameters of the audio of the plurality of preset channels are different, and the playing parameters at least comprise the volume of each loudspeaker for playing the audio.

Specifically, when the audio information received by the vehicle includes audio of a plurality of preset channels, that is, the speakers need to output the audio of the plurality of preset channels, the audio of the target channel in the plurality of preset channels is subjected to a sound reduction process, so that the audio of the plurality of preset channels is different in volume of each speaker.

Alternatively, the sound reduction processing may be to reduce the volume of the audio of the target channel in the plurality of preset channels when the respective speakers play, for example, reduce the volume of the audio of the target channel when the speakers play or reduce the volume of the audio of the target channel in a certain speaker.

Note that, among channels played by speakers, for a channel with a volume of 0, this may be achieved by setting the volume of the target channel in the current speaker to 0, or by not transmitting audio data of a channel with a volume of 0 to the current speaker.

Optionally, the priority ranking of the plurality of preset channels may be determined according to the play priorities of the plurality of preset channels; and determining a preset channel in the target sequencing range as a target channel.

Specifically, based on a preset playing priority order, the acquired plurality of preset channels are subjected to playing priority ordering to obtain an ordering result of the plurality of preset channels, and the preset channels meeting a target ordering range are determined to be target channels.

For example, in the audio information, three channels of a preset channel, a preset channel B and a preset channel C exist, and the preset playing priority order is a > B > C, and after the obtained playing priorities of the three channels of the preset channel a, the preset channel B and the preset channel C are ordered, the preset channel C or the preset channel B and the preset channel C are determined to be the target channels according to the target ordering range (for example, the playing priority is the lowest and the playing priority is located at the last two bits).

Optionally, acquiring an application program operated by a foreground; and determining a preset channel out of the preset channels corresponding to the audio type of the application program as a target channel.

Specifically, as described above, a plurality of APPs on the vehicle play audio inside the vehicle through the speakers, the vehicle may acquire APP information that the foreground is running, and after acquiring, determine a preset channel other than a preset channel corresponding to the audio type of the APP as a target channel.

For example, the vehicle runs a navigation APP, the preset channels corresponding to the navigation APP are navigation channels, and the preset channels except the navigation channels are determined to be target channels needing sound reduction processing. If the acquired audio information to be played comprises the audio of the navigation channel and the audio of the multimedia channel, determining the multimedia channel as a target channel.

Step 013: and playing the audio of a plurality of preset channels according to the audio information after the sound reduction processing.

Specifically, according to the playing parameters of each preset channel obtained after the sound reduction processing, the volume of each loudspeaker when playing each preset channel is determined, so that the playing of the audio information after the sound reduction processing is realized, and the user can distinguish the sound of each preset channel and solve the problem of sound conflict due to the fact that the playing parameters of the audio of a plurality of preset channels are different.

According to the audio playing method, the audio information to be played is obtained, under the condition that the audio information comprises the audio of a plurality of preset channels, the audio of the target channel in the preset channels is subjected to the sound reduction processing, so that the audio of the target channel is different from the playing parameters of the audio of other preset channels in the preset channels, the playing parameters at least comprise the volume of the audio played by each loudspeaker, and therefore when the audio information subjected to the sound reduction processing is played, the audio of the target channel is distinguished from the audio of the other channels, a user can clearly distinguish the audio of the target channel from the audio of the other channels, and the problem of audio conflict of different channels is solved.

Referring to fig. 3, in certain embodiments, step 012: in the case that the audio information includes audio of a plurality of preset channels, performing a sound reduction process on audio of a target channel in the plurality of preset channels, so that playing parameters of the audio of the target channel and audio of other preset channels in the plurality of preset channels are different, wherein the playing parameters at least include volumes of audio played by speakers, and further include:

step 0121: synchronously reducing the volume of the audio of the target channel in each loudspeaker;

specifically, the method is realized by synchronously reducing the volume of a target channel in each loudspeaker and playing the audio subjected to the sound reduction processing in each loudspeaker. That is, when the audio information includes a plurality of preset channels, the volume of the target channel is reduced, and the preset channels with the audio parameters of the target channel reduced synchronously are played at the respective speakers, thereby realizing the sound reduction processing of the target channel.

For example, the vehicle has a speaker a and a speaker B, and the received audio information includes audio of a multimedia channel and a navigation channel, where the preset volumes of the multimedia channel and the navigation channel are both 50. And determining that the target sound channel is a multimedia sound channel, namely, the multimedia sound channel needs to be subjected to sound reduction processing, and then the vehicle reduces the volume of the multimedia sound channel to 10, and at the moment, the loudspeaker A and the loudspeaker B play the audio comprising the multimedia sound channel according to the volume of the multimedia sound channel subjected to sound reduction processing.

Referring to fig. 4, in certain embodiments, step 012: in the case that the audio information includes audio of a plurality of preset channels, performing a sound reduction process on audio of a target channel in the plurality of preset channels, so that playing parameters of the audio of the target channel and audio of other preset channels in the plurality of preset channels are different, wherein the playing parameters at least include volumes of audio played by speakers, and further include:

step 0122: the volume of the audio of the target channel in the first target speaker is synchronously reduced, and the first target speaker is other speakers except for the speaker positioned at the first target azimuth.

Specifically, the volume of the audio of the target channel in the first target speaker is synchronously reduced, the volume is not reduced in other speakers except for the speaker positioned in the first target direction, and finally the audio subjected to the sound reduction processing is played in each speaker.

For example, there are two speakers a and two speakers B on the vehicle, the position of the rear row (the seat other than the driver's seat and the passenger's seat) of the vehicle is determined as the first target position, and the two speakers a are disposed at the first target position, and then the other two speakers B other than the speakers a disposed at the first target position are the first target speakers. At this time, the received audio information includes the audio of the system channel and the navigation channel, the target channel is the navigation channel, and the preset volumes of the navigation channel and the system channel are both 50, so that the volumes of the audio of the navigation channel in the two speakers B on the vehicle driver's seat and the co-driver's seat are synchronously reduced to 20.

Optionally, the volume of the audio of the preset channel outside the target channel is synchronously reduced in the second target speaker, the second target speaker is other speakers outside the speaker located at the second target azimuth, and the first target azimuth and the second target azimuth are different.

Optionally, the method is applied to a vehicle, the vehicle comprises a head and a tail, the first target position is one of the position of the head and the position of the tail, and the second target position is the other of the position of the head and the position of the tail.

Specifically, the first target azimuth is different from the second target azimuth, the vehicle comprises a head and a tail, and when the azimuth of the head is determined to be the first target azimuth, the azimuth of the tail is determined to be the second target azimuth; or determining the position of the tail as a first target position, and determining the position of the head as a second target position. The volume of the speakers in different target orientations is synchronously reduced to realize the audio frequency downconversion processing.

For example, the description will be given taking the position of the vehicle tail as the first target position, the position of the vehicle head as the second target position, the speaker a being located at the vehicle tail (i.e., the first target position), and the speaker B being located at the vehicle head (i.e., the second target position). Assuming that the audio information received at this time includes audio of the multimedia channel and audio of the system channel, the initial volume is 50, and the target channel is determined to be the multimedia channel, the volume of the multimedia channel in the speaker B (for example, the target channel is reduced to 0) can be reduced, and then the volume of the system channel in the speaker a (for example, the target channel is reduced to 0) can be synchronously reduced, so that the multimedia audio is played at the tail of a vehicle, the system audio is played at the head of a vehicle, and the audio of different channels is played through different directions, so that the problem that the audio of a plurality of channels are simultaneously played, and the problem that the user is difficult to distinguish is solved.

Optionally, the preset channels other than the target channel include a plurality of channels, and the method for playing audio further includes: the volume of the audio of each preset channel outside the target channel in the corresponding third target loudspeaker is synchronously reduced, the third target loudspeaker is other loudspeakers except the loudspeaker positioned at the corresponding third target azimuth, the third target azimuth is different from the first target azimuth, and the third target azimuth corresponding to each preset channel outside the target channel is different from each other.

Specifically, when the audio information to be played acquired by the vehicle in actual use includes a plurality of preset channels, the preset channels other than the target channel include a plurality of preset channels.

Taking the left side of the vehicle body as the third target azimuth of the system channel, the navigation channel and the communication channel as an example for explanation, the system channel, the navigation channel and the communication channel have a third target loudspeaker B at the head, a third target loudspeaker A at the tail and a third target loudspeaker D at the right side of the vehicle body. Assuming that the audio information received at this time includes audio of a multimedia channel, a system channel, a navigation channel and a communication channel, the initial volume is 50, the target channel is determined to be the multimedia channel, the first target azimuth is the tailstock azimuth of the vehicle,

(2) Any two channels of the system channel, the navigation channel and the communication channel have the same third target azimuth.

For example, the system channel and the navigation channel each take the left side position of the vehicle body as a third target position, and the communication channel takes the right side position of the vehicle body as a third target position; or the system sound channel and the communication sound channel are both in the third target azimuth of the left side azimuth of the vehicle body, and the navigation sound channel is in the third target azimuth of the right side azimuth of the vehicle body; or the navigation sound channel and the communication sound channel are both in the third target direction of the left side direction of the vehicle body, the system sound channel is in the third target direction of the right side direction of the vehicle body, and the like.

Taking the system sound channel and the navigation sound channel as the third target azimuth, taking the car body left azimuth of the car as the third target azimuth for the communication sound channel, taking the car body right azimuth of the car as the third target azimuth for the illustration, the car head of the car is provided with a third target loudspeaker B, the car tail of the car is provided with a third target loudspeaker A, the right side of the car is provided with a third target loudspeaker D, and the car head of the car is provided with a third target loudspeaker B, the car tail of the car is provided with a third target loudspeaker A, and the left side of the car is provided with a third target loudspeaker C. Assuming that the audio information received at this time includes audio of the multimedia channel, the system channel, the navigation channel, and the communication channel, the initial volume is 50, the target channel is determined to be the multimedia channel, the first target direction is the tail direction of the vehicle, the volume of the multimedia channel in the first target speaker (i.e., speaker B, speaker C, and speaker D) may be reduced (e.g., reduced to 0), the volume of the system channel in the corresponding third target speaker (i.e., speaker B, speaker a, and speaker D) may be reduced (e.g., reduced to 0), the volume of the navigation channel in the corresponding third target speaker (i.e., speaker B, speaker a, and speaker D) may be reduced (e.g., reduced to 0), and the volume of the communication channel in the corresponding third target speaker (i.e., speaker B, speaker a, and speaker C) may be reduced (e.g., reduced to 0).

(3) The system channel, the navigation channel, and the communication channel have different third target orientations.

For example, the third target position of the system channel is the head position of the vehicle, the third target position of the navigation channel is the left side position of the body of the vehicle, and the third target position of the communication channel is the right side position of the body of the vehicle; or the third target azimuth of the system sound channel is the left side azimuth of the vehicle body, the third target azimuth of the navigation sound channel is the right side azimuth of the vehicle body, the third target azimuth of the communication sound channel is the head azimuth of the vehicle, and the like.

Taking the third target azimuth of the system sound channel as the head azimuth of the vehicle, the third target azimuth of the navigation sound channel as the left azimuth of the vehicle body, and the third target azimuth of the communication sound channel as the right azimuth of the vehicle body as an example, the system sound channel is described, wherein the tail of the vehicle is provided with a third target loudspeaker A, the left side of the vehicle is provided with a third target loudspeaker C, and the right side of the vehicle is provided with a third target loudspeaker D; for a navigation sound channel, a third target loudspeaker B is arranged on the head of the vehicle, a third target loudspeaker D is arranged on the right side of the body of the vehicle, and a third target loudspeaker A is arranged on the tail of the vehicle; for the communication channel, the vehicle head is provided with a third target loudspeaker B, the left side of the vehicle body is provided with a third target loudspeaker C, and the vehicle tail is provided with a third target loudspeaker A.
