[0040] Currently, vehicles are equipped with speakers for playing music and other audio content, which are essential components of the car entertainment system.
[0041] However, when multiple vehicles are parked within a certain range, for example, when a team gets off the vehicle to rest during a trip or gets off the vehicle to move around after arriving at the destination, if the user wants multiple vehicles to play the target audio at the same time, the user needs to control each vehicle to play the target audio at the same time. The operation is cumbersome and random, the probability of achieving synchronous playback is low, and the playback effect is poor.
[0042] In response to the defects of related technologies in synchronous audio playback in multiple vehicles, the embodiments of the present disclosure provide an audio playback method, device, vehicle and medium, which can connect multiple vehicles to the same network, combine the speakers in multiple vehicles into a whole, and simultaneously control the audio playback of each vehicle through the network, so that multiple vehicles can synchronously play the same audio, thereby improving the synchronous playback effect of the audio.
[0043] The audio playback method provided by the embodiment of the present disclosure may be executed by a vehicle, which may be understood as any device with processing and computing capabilities, and is equipped with at least one speaker.
[0044] In order to better understand the inventive concept of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure are described below in conjunction with exemplary embodiments.
[0045] Figure 1 is a flowchart of an audio playback method provided by an embodiment of the present disclosure, which is applied to a first vehicle, such as Figure 1As shown, the audio playback method provided in this embodiment includes the following steps:
[0046] Step 110: In response to receiving the audio synchronous playback instruction, the first vehicle establishes a target network.
[0047] In the disclosed embodiment, when the user wants multiple vehicles within a certain range to play the target audio at the same time, any one of the multiple vehicles can be determined as the first vehicle, and an audio synchronous playback instruction can be input to the first vehicle. For example, a voice instruction for audio synchronous playback can be input to the first vehicle, and the audio synchronous playback button of the first vehicle can be clicked, slid, etc. to implement the input of the start playback instruction. The first vehicle can respond to the received audio synchronous playback instruction to form a target network, wherein the target network can be an ad-hoc network. In other words, the first vehicle can be used as the master node of the ad-hoc network, and the other second vehicles to be added to the ad-hoc network can be subsequently notified so that the other second vehicles can be added to the ad-hoc network as slave nodes. When all vehicles to be communicated are added to the ad-hoc network, the quality inspection of each vehicle can be realized to communicate.
[0048] Among them, an ad hoc network can be understood as a local wireless communication network that allows individual communication devices, that is, individual vehicles, to communicate directly without a pre-configured infrastructure and without relying on a central infrastructure or network manager.
[0049] Among them, the process of the first vehicle establishing the target network can refer to related technologies and will not be described in detail here.
[0050] Step 120: Notify at least one second vehicle other than the first vehicle to access the target network.
[0051] In the disclosed embodiment, after the target network is established, the first vehicle may notify at least one second vehicle other than the first vehicle to access the target network. In other words, the at least one second vehicle other than the first vehicle may be used as a slave node of the target network.
[0052] In some embodiments, the first vehicle may broadcast a target network identifier of the target network to the target network, so that the second vehicle can access the target network corresponding to the target network identifier.
[0053] In the embodiment of the present disclosure, the target network identifier may be understood as identification information that can uniquely represent the identity information of the target network.
[0054] For example, Figure 2a is a schematic diagram of a network connection provided by an embodiment of the present disclosure, such as Figure 2aAs shown, 200 is a target network, which is an ad-hoc network here, 201 is a first vehicle, 202 , 203 , 204 are second vehicles, and the first vehicle 201 controls the audio playback of the second vehicles 202 , 203 , 204 through the target network 200 .
[0055] Step 130: In response to receiving a start playing instruction of the target audio, send a start playing instruction to at least one second vehicle based on the target network to control the at least one second vehicle to play the target audio simultaneously with the first vehicle.
[0056] In the disclosed embodiment, a user can input a start playback instruction for the target audio to the first vehicle. For example, a voice instruction to start playing the target audio can be input to the first vehicle, and a button for starting to play the target audio of the first vehicle can be clicked, slid, or the like to be performed to input the start playback instruction. The first vehicle can, in response to receiving the start playback instruction for the target audio, send a start playback instruction to at least one second vehicle based on the target network to control the at least one second vehicle to play the target audio simultaneously with the first vehicle.
[0057] For example, Figure 2b is a schematic diagram of a vehicle distribution provided by an embodiment of the present disclosure, such as Figure 2b As shown, Figure 2b There are a total of 4 vehicles, each of which is equipped with at least one speaker that can play audio, and the middle is the audience.
[0058] In some embodiments, in response to receiving a start playback instruction for the target audio, the first vehicle can send the start playback instruction for the target audio to at least one second vehicle based on the target network, so that the at least one second vehicle respectively obtains the audio identifier of the target audio and the start playback time of the target audio from the start playback instruction, and plays the target audio corresponding to the audio identifier at the start playback time simultaneously with the first vehicle.
[0059] In the disclosed embodiment, the first vehicle may, in response to receiving a start playing instruction for the target audio, obtain an audio identifier and a start playing time of the target audio from the start playing instruction. In the disclosed embodiment, the first vehicle may send a start playing instruction for the target audio to each second vehicle based on the target network, so that each second vehicle obtains the audio identifier and the start playing time of the target audio from the start playing instruction, and plays the target audio corresponding to the audio identifier at the start playing time.
[0060] In some other embodiments, in response to receiving a start playing instruction of the target audio, sending a start playing instruction to at least one second vehicle based on the target network to control the at least one second vehicle to play the target audio simultaneously with the first vehicle may include steps 1301-1303:
[0061] Step 1301, in response to receiving a start playing instruction of a target audio, obtaining the distance between a first vehicle and a target audience, and for each second vehicle, sending a request for obtaining the distance between the second vehicle and the target audience to the second vehicle based on a target network.
[0062] For example, the distance between the vehicle and the target audience can be obtained by a distance measuring device arranged on the vehicle, which may include a radar or other equipment.
[0063] Step 1302: For each second vehicle, receiving the distance between the second vehicle and the target audience sent by the second vehicle based on the target network.
[0064] Step 1303: for each of the first vehicle and at least one second vehicle, determine a target playback volume corresponding to the distance between the vehicle and the target audience based on the corresponding relationship between the distance between the vehicle and the target audience and the playback volume, wherein the distance is positively correlated with the playback volume.
[0065] Among them, the distance between the vehicle and the target audience is positively correlated with the playback volume, that is, the greater the distance between the vehicle and the target audience, the louder the playback volume of the vehicle, and the smaller the distance between the vehicle and the target audience, the smaller the playback volume of the vehicle.
[0066] Step 1304: for each second vehicle, carry the target playback volume corresponding to the distance between the second vehicle and the target audience in the start playback instruction, and update the start playback instruction carrying the target playback volume to the start playback instruction corresponding to the second vehicle.
[0067] In the disclosed embodiment, for each second vehicle, in order to enable the second vehicle to play the target audio at a target playback volume corresponding to the distance between the second vehicle and the target audience, the first vehicle may carry the target playback volume corresponding to the distance between the second vehicle and the target audience in the start playback instruction, and update the start playback instruction after carrying the target playback volume to the start playback instruction corresponding to the second vehicle.
[0068] Step 1305: For each second vehicle, a start play instruction corresponding to the second vehicle is sent to the second vehicle based on the target network to control the second vehicle to play the target audio simultaneously according to the target play volume in the start play instruction and the target play volume corresponding to the distance between the first vehicle and the target audience.
[0069] In the disclosed embodiment, for each second vehicle, the first vehicle can send a start playback instruction corresponding to the second vehicle to the second vehicle based on the target network to control the second vehicle to play the target audio simultaneously according to the target playback volume in the start playback instruction and the target playback volume corresponding to the distance between the first vehicle and the target audience.
[0070] In the disclosed embodiment, for each second vehicle, in order to enable the second vehicle to play the target audio at the target playback volume corresponding to the distance between the second vehicle and the target audience, the first vehicle can carry the target playback volume corresponding to the distance between the second vehicle and the target audience in the start playback instruction, and update the start playback instruction after carrying the target playback volume to the start playback instruction corresponding to the second vehicle. The start playback instruction corresponding to the second vehicle is sent to the second vehicle based on the target network, and the second vehicle is controlled to play the target audio at the same time as the first vehicle at the target playback volume corresponding to the distance between the second vehicle and the target audience; wherein the first vehicle plays the target audio at the target playback volume corresponding to the distance between the first vehicle and the target audience.
[0071] In this way, the user can clearly hear the target audio being played at all distances from the vehicle, thereby improving the effect of simultaneous audio playback.
[0072] In the embodiment of the present disclosure, in response to receiving an audio synchronous playback instruction, a first vehicle establishes a target network; notifies at least one second vehicle other than the first vehicle to access the target network; in response to receiving a start playback instruction of the target audio, a start playback instruction is respectively sent to at least one second vehicle based on the target network to control at least one second vehicle to play the target audio simultaneously with the first vehicle. Multiple vehicles can be connected to the same network, speakers in multiple vehicles can be combined into a whole, and audio playback of each vehicle can be simultaneously controlled through the network, so that multiple vehicles can play the same audio synchronously, thereby improving the effect of synchronous audio playback.
[0073] Figure 3 is a flowchart of an audio playback method provided by an embodiment of the present disclosure, which is applied to a first vehicle, such as Figure 3 As shown, the audio playback method provided in this embodiment includes the following steps:
[0074] Step 310: In response to receiving the audio synchronous playback instruction, the first vehicle establishes a target network.
[0075] Step 320: Notify at least one second vehicle other than the first vehicle to access the target network.
[0076] Step 330: Receive a time synchronization request sent by at least one second vehicle.
[0077] In the disclosed embodiment, since the time information of the second vehicle may be out of sync with the first vehicle, in order to ensure the synchronous playback effect of the audio, the Network Time Protocol (NTP) can be used for time synchronization. The Network Time Protocol is a protocol used to synchronize device time in a computer network.
[0078] In the disclosed embodiment, the second vehicle may send a time synchronization request to the first vehicle, that is, the second vehicle requests time synchronization with the first vehicle, and the first vehicle may receive at least one time synchronization request sent by the second vehicle.
[0079] Step 340: For each second vehicle, in response to a time synchronization request of the second vehicle, the first real-time time of the first vehicle is sent to the second vehicle, so that the second real-time time of the second vehicle controlling itself is synchronized with the first real-time time.
[0080] In the disclosed embodiment, for each second vehicle, after receiving the time synchronization request sent by the second vehicle, the first vehicle can respond to the time synchronization request of the second vehicle and send the first real-time time of the first vehicle to the second vehicle, so that the second real-time time of the second vehicle controlling itself is synchronized with the first real-time time, that is, the second real-time time is the same as the first real-time time.
[0081] The first real time is the real time of the first vehicle, and the second real time is the real time of the second vehicle.
[0082] Step 350, based on the synchronization of the second real-time time with the first real-time time, in response to receiving a start playing instruction of the target audio, a start playing instruction is sent to at least one second vehicle based on the target network to control at least one second vehicle to play the target audio simultaneously with the first vehicle.
[0083] In an embodiment of the present disclosure, based on the synchronization of the second real-time time with the first real-time time, the first vehicle can respond to receiving a start playing instruction of the target audio by sending a start playing instruction to at least one second vehicle based on the target network, so as to control the at least one second vehicle to play the target audio simultaneously with the first vehicle.
[0084] In this way, multiple vehicles can be connected to the same network, the speakers in multiple vehicles can be combined into a whole, the time of multiple vehicles can be synchronized, and the audio playback of each vehicle can be controlled simultaneously through the network, so that multiple vehicles can play the same audio synchronously, further improving the synchronous playback effect of the audio.
[0085] In some embodiments of the present disclosure, after the first vehicle forms the target network, when the user does not need multiple vehicles within a certain range to play the target audio at the same time, a stop instruction for the synchronous audio playback can be input to the first vehicle. For example, a voice instruction to stop the synchronous audio playback can be input to the first vehicle, and the stop instruction for the synchronous audio playback can be input by clicking, sliding, etc. on the stop button of the synchronous audio playback of the first vehicle. The first vehicle can delete the target network in response to receiving the stop instruction for the synchronous audio playback.
[0086] Figure 4 is a flowchart of an audio playback method provided by an embodiment of the present disclosure, which is applied to a second vehicle, such as Figure 4 As shown, the audio playback method provided in this embodiment includes the following steps:
[0087] Step 410: The second vehicle accesses the target network, which is established by the first vehicle.
[0088] In the disclosed embodiment, the second vehicle can access the target network, which is formed by the first vehicle. The target network can be understood as a local wireless communication network that allows each communication device to communicate directly without a pre-configured infrastructure, without relying on a central infrastructure or network manager. For example, the target network can be an Ad-hoc Network.
[0089] In some embodiments, the second vehicle accessing the target network may include steps 4101-4102:
[0090] Step 4101: adjust the network mode to pairing mode and search for a network identifier.
[0091] In the disclosed embodiment, the second vehicle may adjust the network mode to a pairing mode and search for a network identifier.
[0092] Step 4102: In response to searching for the target network identifier, access the target network corresponding to the target network identifier.
[0093] In the disclosed embodiment, after searching for the target network identifier, the second vehicle may access the target network corresponding to the target network identifier in response to searching for the target network identifier.
[0094] Step 420: Receive a start playing instruction of the target audio sent by the first vehicle based on the target network.
[0095] In the disclosed embodiment, after accessing the target network, the second vehicle may receive a start playing instruction of the target audio sent by the first vehicle based on the target network.
[0096] Step 430: In response to the start playing instruction of the target audio sent by the first vehicle, play the target audio simultaneously with the first vehicle.
[0097] In an embodiment of the present disclosure, after receiving a start playing instruction for the target audio sent by the first vehicle, the second vehicle can respond to the start playing instruction for the target audio sent by the first vehicle and play the target audio based on the start playing instruction, so that the second vehicle plays the target audio simultaneously with the first vehicle.
[0098] In some embodiments, in response to a start playing instruction of the target audio sent by the first vehicle, playing the target audio simultaneously with the first vehicle may include steps 4301-4302:
[0099] Step 4301: In response to a target audio start playing instruction sent by a first vehicle, an audio identifier of the target audio and a start playing time of the target audio are obtained from the start playing instruction.
[0100] In an embodiment of the present disclosure, after receiving a start playback instruction for the target audio sent by the first vehicle, the second vehicle can respond to the start playback instruction for the target audio sent by the first vehicle based on the target network, and obtain the audio identifier of the target audio and the start playback time of the target audio from the start playback instruction.
[0101] Step 4302: Play the target audio corresponding to the audio identifier simultaneously with the first vehicle at the start playing time.
[0102] In the disclosed embodiment, the second vehicle may play the target audio corresponding to the audio identifier at the start playback time, and at this time, the first vehicle also plays the target audio at the start playback time.
[0103] In this way, multiple vehicles can be connected to the same network, the speakers in multiple vehicles can be combined into a whole, and the audio playback of each vehicle can be controlled simultaneously through the network, so that multiple vehicles can play the same audio synchronously, improving the synchronous playback effect of the audio.
[0104] Figure 5 is a flowchart of an audio playback method provided by an embodiment of the present disclosure, which is applied to a second vehicle, such as Figure 5 As shown, the audio playback method provided in this embodiment includes the following steps:
[0105] Step 510: The second vehicle accesses the target network, which is established by the first vehicle.
[0106] Step 520: Send a time synchronization request to the first vehicle based on the target network, and determine the time to send the time synchronization request.
[0107] In the disclosed embodiment, since the time information of the second vehicle may be out of sync with that of the first vehicle, in order to ensure the synchronous playback effect of the audio, the second vehicle can send a time synchronization request to the first vehicle based on the target network, that is, the second vehicle requests time synchronization with the first vehicle and determines the time of sending the time synchronization request.
[0108] Step 530: Receive the first real-time time of the first vehicle fed back by the first vehicle based on the time synchronization request and the sending time of the first real-time time, and determine the receiving time of the first real-time time.
[0109] In an embodiment of the present disclosure, after receiving a time synchronization request sent by the second vehicle, the first vehicle can send the first real-time time of the first vehicle to the second vehicle. The second vehicle can receive the first real-time time of the first vehicle fed back by the first vehicle based on the time synchronization request, and determine the reception moment of the first real-time time.
[0110] Step 540: Calculate the difference between the receiving time and the sending time, and determine half of the difference as the network delay duration.
[0111] In the disclosed embodiment, the second vehicle can calculate the difference between the receiving time of the first real-time time and the sending time of the first real-time time, and determine half of the difference as the network delay time. For example, if the sending time of the time synchronization request is 12 o'clock and the receiving time of the first real-time time is 12:01, the network delay time is half of the difference between 12:01 and 12 o'clock, that is, 0.5 seconds.
[0112] Step 550: Calculate the target time after the first real-time time is extended by the network delay time.
[0113] In the disclosed embodiment, the second vehicle may calculate the target time after the first real-time time is extended by the network delay duration.
[0114] For example, if the first real time is 12 o'clock and the network delay is 1 second, the target time is 12:01.
[0115] Step 560: Adjust the second real-time time of the second vehicle to the target time, so that the second real-time time is synchronized with the first real-time time.
[0116] In the disclosed embodiment, the second vehicle may adjust the second real-time time of the second vehicle to the target time so that the second real-time time is synchronized with the first real-time time.
[0117] Step 570: Receive a start playing instruction of the target audio sent by the first vehicle based on the target network.
[0118] Step 580: Based on the synchronization of the second real time with the first real time, in response to a start playing instruction of the target audio sent by the first vehicle, play the target audio simultaneously with the first vehicle.
[0119] In the disclosed embodiment, the second vehicle can play the target audio simultaneously with the first vehicle in response to a start playing instruction of the target audio sent by the first vehicle on the basis of synchronizing the second real time with the first real time.
[0120] In this way, multiple vehicles can be connected to the same network, the speakers in multiple vehicles can be combined into a whole, the time of multiple vehicles can be synchronized, and the audio playback of each vehicle can be controlled simultaneously through the network, so that multiple vehicles can play the same audio synchronously, further improving the synchronous playback effect of the audio.
