With the rapid development of communication technology, many BIS/BIG are involved in the communication environment, such as a station reporter in a subway, an alarm, a doorbell in a home, an airport boarding broadcast, or a boarding broadcast at a train station. Currently, the type of protocol broadcast defined by the SIG organization is listened to through headphones/speakers. The mobile phone is used as an assistant party to receive the broadcasted configuration information, such as the broadcast receiving password corresponding to each broadcasting device.

However, most of the broadcasts are silent packets, and audio playing (such as boarding prompt, stop report, fire alarm and the like) can be performed only when needed, so if the broadcasts are listened by the earphone according to the SIG scheme, the broadcasts need to be listened by the earphone continuously when no sound is available, otherwise, the broadcasts cannot be received in time when the sound comes, and the defect of excessive power consumption of the earphone is caused; and if the current earphone/stereo plays the voice or music of the mobile phone/TV, the problem that the broadcasting audio data playing conflicts with other audio playing time sequences exists, namely the conflict of time slices is very serious.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

An embodiment of the present application provides an audio transmission method, and fig. 3 is a schematic implementation flow diagram of the audio transmission method provided in the embodiment of the present application, as shown in fig. 3, in the embodiment of the present application, an audio transmission method executed by an audio transmission system may include the following steps:

step 100, after the audio relay device establishes wireless communication connection with the audio output device, the audio relay device obtains target broadcast audio data.

In the embodiment of the application, the audio transmission system may acquire the target broadcast audio data through the audio relay device after the audio relay device establishes the wireless communication connection with the audio output device.

It should be noted that, in the embodiments of the present application, the audio relay device may be any wireless communication electronic device with an audio acquisition and transmission function. Optionally, the audio relay device is not limited to an electronic device such as a smart phone, a gateway device (e.g., a router), a tablet Computer, a television, a Personal Computer (PC), and a notebook Computer.

It should be noted that, in the embodiments of the present application, the audio output device may be any electronic device with wireless communication and having an audio playing function. Specifically, the wireless communication may be bluetooth communication. Optionally, the audio output device is not limited to a bluetooth headset or a bluetooth sound.

It can be understood that, in the embodiment of the application, if the audio data in the audio relay device is to be played using a bluetooth headset or a bluetooth sound, the audio relay device may be an electronic device with a bluetooth communication function. Here, the audio transmission system may first establish a bluetooth communication connection between the audio relay apparatus and the audio output apparatuses.

Specifically, the audio relay device may send a bluetooth connection request to the audio output device, wait to receive pairing connection confirmation information of the audio output device, and when receiving a pairing connection instruction returned by the audio output device, the audio relay device may establish bluetooth communication connection with the audio transmission device based on the pairing connection instruction.

It should be noted that, in the embodiment of the present application, the bluetooth communication connection is not limited to a conventional bluetooth physical link (ACL), but may also be a CIG/CIS link newly introduced by BT 5.2.

Further, in the embodiment of the present application, after the audio relay device establishes the communication connection with the audio output device, the audio relay device may first acquire the broadcast audio data. It should be understood that, in the embodiment of the present application, the audio relay apparatus may acquire the broadcast audio data from the broadcasting apparatus.

It should be understood that the broadcast device may be a device capable of BIG/BIS broadcasting, or a device capable of broadcasting through a speaker/speaker. Such as a station reporter in a subway, an alarm, a doorbell at home, a boarding reporter at an airport or a boarding reporter at a train station.

It can be understood that, in the embodiment of the present application, in order to ensure timely listening to a broadcast, the audio relay device needs to be always kept in a broadcast listening state, however, when outputting and playing received broadcast audio data through the audio output device, it is possible that other audio data are currently being output and played, and in order to avoid time sequence conflict between playing of the broadcast audio data and other currently played audio data, the audio relay device needs to perform real-time detection on a current audio output state while receiving the broadcast audio data.

Further, in the embodiment of the present application, after the audio transmission system obtains the target broadcast audio data through the audio relay device and detects the current audio output state, the audio relay device may further determine whether to execute the audio mixing process of the broadcast audio data according to the current audio output state.

And step 110, if the current state of the audio relay device is outputting the initial audio data, the audio relay device generates audio data to be transmitted according to the initial audio data and the target broadcast audio data.

And step 120, the audio transfer equipment sends the audio data to be transmitted to the audio output equipment.

In the embodiment of the application, after the audio transmission system acquires the broadcast audio data through the audio relay device and detects the current audio output state, if the current state of the audio relay device is to output the initial audio data, the audio relay device may generate the audio data to be transmitted according to the initial audio data and the target broadcast audio data.

It should be noted that, in the embodiments of the present application, the initial audio data refers to other non-broadcast audio data that the audio relay apparatus currently sends to the audio output apparatus.

It should be noted that, in the embodiment of the present application, the current state of the audio relay device may be that the audio relay device currently sends other non-broadcast audio data to the audio output device, so as to play the other non-broadcast audio data through the audio output device; on the other hand, the current state of the audio relay device may also be that the audio relay device does not currently send any audio data to the audio output device, that is, the current audio output device does not play any other non-broadcast audio data.

Here, if the audio relay device determines that the current state is outputting the initial audio data, in order to not affect the playing of other initial audio data and allow the user to listen to the broadcast audio data in time, the audio relay device may obtain the audio data to be transmitted based on the mixing processing of the target broadcast audio data and the initial audio data, and transmit the data to be transmitted to the audio output device.

Specifically, fig. 4 is a schematic view of an implementation flow chart of an audio transmission method provided in an embodiment of the present application, and as shown in fig. 4, in the embodiment of the present application, a method for generating audio data to be transmitted by an audio relay device according to initial audio data and target broadcast audio data may include the following steps:

step 111, if the current state of the audio relay device is to output the initial audio data, the audio relay device performs audio mixing processing on the initial audio data and the target broadcast audio data to generate audio data after audio mixing; the mixed data comprises target broadcast audio data with a first identification level and initial audio data with a second identification level; the first recognition level is greater than the second recognition level.

It can be understood that, since the mixing process is to play a plurality of audio data simultaneously, in order to enable a user to more effectively listen to the broadcast audio data, the audio relay device needs to make the broadcast audio data more prominent when playing the broadcast audio data on the audio output device, and therefore, in the embodiment of the present application, the audio relay device needs to perform a mixing operation on the two audio data, namely, the broadcast audio data and the original audio data, so that the target broadcast audio data in the mixed data is more easily identified by the user than the original audio data.

Specifically, the audio relay device may enable, through the audio mixing process, the identification level of the target broadcast audio data, that is, the first identification level, to be greater than the identification level of the initial audio data, that is, the second identification level, in the mixed data.

Optionally, the audio relay device may make the target broadcast audio data in the audio data after the audio mixing processing more prominent through volume adjustment processing, frequency adjustment processing, and the like.

In detail, fig. 5 is a schematic flow chart of a third implementation of an audio transmission method provided in the embodiment of the present application, and as shown in fig. 5, in the embodiment of the present application, an audio relay device performs audio mixing processing on initial audio data and target broadcast audio data, and a method for generating audio data after audio mixing may include the following steps:

and step 111a, if the current state of the audio relay device is outputting the initial audio data, the audio relay device performs volume adjustment processing on the target broadcast audio data according to the first weight value to obtain the target broadcast audio data with the first volume.

And step 111b, carrying out volume adjustment processing on the initial audio data according to the second weight value to obtain initial audio data with a second volume.

And step 111c, generating the audio data after mixing based on the target broadcast audio data with the first volume and the initial audio data with the second volume.

It should be noted that, in the embodiment of the present application, the audio relay device may perform volume adjustment processing on the audio data by using weights representing different volume sizes.

Specifically, the audio relay device may perform volume adjustment processing on the broadcast audio data according to the first weight value, so as to obtain broadcast audio data with a first volume; and meanwhile, carrying out volume adjustment processing on the initial audio data according to a second weight value smaller than the first weight value so as to obtain the initial audio data with a second volume.

Further, the audio relay device may generate the mixed data based on the two audio data with different volume levels.

Specifically, the audio relay device may perform decoding processing on the broadcast audio data and the currently output initial audio data, further perform audio mixing processing on the decoded data based on the volume weight value to obtain mixed audio data, encode the mixed audio data again to obtain mixed audio data, and use the mixed audio data as the audio data to be transmitted.

And step 112, the audio transit device takes the audio data after the audio mixing as audio data to be transmitted.

Further, after the audio relay device performs sound mixing processing on the sound, the audio relay device may forward the audio data after sound mixing to the audio output device for playing.

In detail, the audio relay device may perform sound mixing processing by weakening other non-broadcast initial audio data currently being played and enhancing the broadcast audio data. For example, the audio relay apparatus may reduce the sound of other initial audio data currently being played to highlight the sound of the broadcast audio data.

Here, if the audio relay device determines that the current state is outputting the initial audio data, in order to avoid the defect of unclear sound generated by the audio mixing process, so as to ensure that the user clearly and effectively listens to the broadcast audio data, the audio relay device may perform the sending process of different audio data according to the time sequence.

Specifically, fig. 6 is a schematic view of an implementation flow of an audio transmission method provided in an embodiment of the present application, and as shown in fig. 6, in the embodiment of the present application, a method for generating, by an audio relay device, audio data to be transmitted according to initial audio data and target broadcast audio data may include the following steps:

and 113, if the current state of the audio transfer device is outputting the initial audio data, the audio transfer device directly takes the initial audio data and the target broadcast audio data as audio data to be transmitted.

Further, the method for sending the audio data to be transmitted to the audio output device by the audio transfer device includes:

and step 121, the audio relay device stops outputting the initial audio data, and sends the target broadcast audio data to the audio output device, so that the audio output device plays the target broadcast audio data.

And step 122, after the target broadcast audio data is sent, the audio relay device continues to send the initial audio data to the audio output device, so that the audio output device continues to play the initial audio data.

In detail, the audio relay device may suspend sending the current initial audio data to the audio output device when receiving the broadcast audio data, and send the broadcast audio data to the audio output device first, so that the audio output device plays the current broadcast audio data.

Further, after the transmission of the broadcast audio data is completed, the audio relay device may continue to transmit the initial audio data to the audio output device, so that the audio output device continues to play the initial audio data next.

For example, when the mobile phone receives a boarding broadcast, at this time, the mobile phone is playing music through the bluetooth headset, the mobile phone pauses music, only the boarding broadcast is played through the headset first, and after the boarding broadcast is played, the mobile phone continues to play music through the headset.

Step 130, the audio output device plays the audio data to be transmitted.

In the embodiment of the application, after the audio output device receives the audio data to be transmitted sent by the audio relay device, the audio output device can play the audio data to be transmitted.

It should be noted that, in the embodiment of the present application, the audio output device adopts different playing strategies for different audio data to be transmitted.

Here, when the data to be transmitted is the mixed audio data obtained by the mixing process, the audio output device plays the broadcast audio data and the initial audio data at different volumes.

Specifically, fig. 7 is a schematic view illustrating an implementation flow of an audio transmission method provided in an embodiment of the present application, as shown in fig. 7, in the embodiment of the present application, after the audio relay device uses the audio data after audio mixing as audio data to be transmitted, and sends the data to be transmitted to the audio output device, that is, after step 120, the method for playing the audio data to be transmitted by the audio output device may include the following steps:

step 131, the audio output device plays the target broadcast audio data according to the first volume, and simultaneously plays the initial audio data according to the second volume.

It should be understood that in the mixed audio data received by the audio output device, the audio relay device has performed volume adjustment processing on the audio data according to different weight values capable of representing the volume, so that the broadcast audio data is more prominent than the original audio data during playing. Therefore, in the embodiment of the present application, the audio output device may play according to a play policy that the volume of the target broadcast audio data is greater than the volume of the initial audio data.

For example, when the mobile phone receives a boarding broadcast, at this time, the mobile phone is playing music through a bluetooth headset, and then the mobile phone may perform sound mixing processing on the boarding broadcast and the music, and may tune the sound of the music down to highlight the sound of the important boarding broadcast; alternatively, the volume of the music data may be directly reduced to 0, and only the boarding broadcast may be played.

Optionally, based on the audio transmission method shown in fig. 6, when the data to be transmitted is different audio data sent according to the time sequence, the audio output device may directly play the received different audio data according to the time sequence.

It should be understood that, since the audio output device is a passive audio playing device, it only passively receives the audio data sent by the audio relay device. Therefore, in the embodiment of the present application, when the audio relay device stops outputting the initial audio data and sends the broadcast audio data, the audio output device only plays the received broadcast audio data at this time; and when the audio transfer equipment finishes outputting the broadcast audio data and continues outputting the initial audio data, the audio output equipment continues playing the initial audio data at the moment. After receiving the target broadcast audio data sent by the audio transfer equipment, the audio output equipment plays the target broadcast audio data; and after the audio output equipment receives the initial audio data sent by the audio transfer equipment, playing the initial audio data.

It should be noted that, if the audio relay device determines that the current state is that no audio data is sent to the audio output device, that is, no initial audio data is output, the audio transmission system may directly send the received broadcast audio data to the audio output device through the audio relay device for playing.

In summary, in the present application, in the audio transmission system, the audio relay device plays a role as a broadcast collector, and the audio relay device may be a mobile phone, a television TV, or a bluetooth gateway. The audio relay device may perform audio decoding on the received broadcast signal, and then forward the obtained broadcast audio data to an audio output device, such as an earphone or a sound device. If the existing song listening service is in progress during forwarding, the broadcasting and the existing music are required to be forwarded to the earphone or the sound after mixed sound processing, or the existing music is suspended to play the broadcasting first. Therefore, the earphone/sound equipment does not need to listen to the broadcast by itself, the broadcast forwarded by the audio relay equipment is received based on the Bluetooth communication connection with the audio relay equipment, and if the Bluetooth communication connection between the audio relay equipment and the earphone is disconnected, the user cannot listen to the broadcast through the earphone.

The embodiment of the application provides an audio transmission method, wherein an audio transmission system comprises an audio transfer device and an audio output device, and after the audio transfer device establishes wireless communication connection with the audio output device, the audio transfer device acquires target broadcast audio data; if the current state of the audio transfer equipment is that the initial audio data are output, the audio transfer equipment performs audio mixing processing on the initial audio data according to the target broadcast audio data to obtain audio data after audio mixing, and sends the audio data after audio mixing to the audio output equipment; the audio output equipment plays the target broadcast audio data according to the first volume and simultaneously plays the initial audio data according to the second volume; wherein the first volume is greater than the second volume. That is to say, in the embodiment of the application, on one hand, audio output equipment such as an earphone/a sound device is not needed to autonomously receive broadcast audio data, but the collection of the broadcast audio data is performed through the audio relay equipment, and the earphone/the sound device only needs to be connected with and receive the audio data forwarded by the audio relay equipment, so that the defect that the power consumption of the earphone is too large is overcome; on the other hand, after the audio transmission system receives the broadcast audio data, the target audio data to be transmitted can be generated according to the broadcast audio data and other currently output audio data, and then the target audio data is played, so that the problem that time sequence conflict exists between the playing of the broadcast audio data and the playing of other audio data is solved, and the system is high in intelligence.

Based on the foregoing embodiment, in a further embodiment of the present application, fig. 8 is a sixth schematic implementation flow chart of an audio transmission method provided in the embodiment of the present application, and as shown in fig. 8, in the embodiment of the present application, a method for an audio transmission system to obtain target broadcast audio data through an audio relay device (step 101) includes the following steps:

step 101a, after the audio relay device establishes wireless communication connection with the audio output device, receiving a wireless broadcast signal sent by the broadcast device.

And step 101b, decoding the wireless broadcast signals to obtain target broadcast audio data.

It should be noted that, in the embodiment of the present application, the broadcasting device may be a Bluetooth Low Energy (BLE) broadcasting device.

Specifically, in the embodiment of the present application, when the external broadcasting device performs broadcast transmission in the form of BIG/BIS, the audio transmission system may receive the wireless broadcast signal transmitted by the broadcasting device through the audio relay device, and decode the wireless broadcast signal to obtain the target broadcast audio data, so that the decoded broadcast audio data may be further transmitted to the audio output device.

It should be understood that the broadcasting device generally has the broadcast receiving authority and the broadcast importance, and before the audio relay device performs the acquisition of the broadcast audio data from the broadcasting device, the audio relay device may first acquire the audio receiving parameters corresponding to the external related broadcasting device through common manners such as network, positioning, or ecological software, and then perform the reception of the wireless broadcast signal based on the audio receiving parameters.

Specifically, in the embodiment of the application, when the audio relay device receives the wireless broadcast signal, the audio relay device may first obtain an audio receiving parameter corresponding to the broadcast device, and then receive the wireless broadcast signal based on the audio receiving parameter.

Optionally, the audio receiving parameter may include an encryption parameter corresponding to a broadcasting device; or the audio receiving parameter may include a priority level corresponding to the broadcasting device; or the audio receiving parameter may include an encryption parameter or a priority level.

Specifically, in a case that the audio receiving parameter includes an encryption parameter, fig. 9 is a seventh implementation flow diagram of the audio transmission method provided in the embodiment of the present application, and as shown in fig. 9, the method for receiving, by the audio transmission system, the wireless broadcast signal sent by the broadcast device through the audio relay device includes:

step 101a1, after the audio relay device establishes wireless communication connection with the audio output device, obtaining the corresponding encryption parameter of the broadcast device.

Step 101a2, receiving a wireless broadcast signal based on the encryption parameters.

In detail, the encryption parameter is not limited to the device name and the broadcast reception password corresponding to the broadcasting device.

Here, after the audio relay device obtains the encryption parameter corresponding to the broadcast device based on the configuration information, the audio relay device may input the device name of the broadcast to be received and the password corresponding to the device name on the parameter setting interface, and the audio relay device may respond to the operation and obtain the receiving authority of the target broadcast signal based on the encryption parameter, so that the target broadcast signal may be further received to obtain the target broadcast audio data.

Specifically, in a case that the audio receiving parameter includes a priority level, fig. 10 is an eighth implementation flow diagram of the audio transmission method provided in the embodiment of the present application, and as shown in fig. 10, the method for receiving, by the audio transmission system, the wireless broadcast signal sent by the broadcast device through the audio relay device includes:

step 101a3, after the audio relay apparatus establishes wireless communication connection with the audio output apparatus, acquiring the priority level corresponding to the broadcasting apparatus.

Step 101a4, receiving the wireless broadcast signal according to the priority level.

It should be understood that there are a plurality of different broadcasting devices outside, and according to the self configuration of the device or the user requirements, there are differences in the priority levels corresponding to the broadcasting devices, for example, the broadcasting priority level corresponding to the fire alarm device is always at the highest priority level; it can be seen that if multiple broadcasts exist at the same time, in order to avoid the problem of conflict generated by broadcast scheduling, the audio relay device may first obtain the broadcast receiving priority corresponding to each broadcast device based on the configuration information of the broadcast device, or a user may manually set the priority level of each broadcast on an operation interface according to actual needs, and then the audio relay device responds to the above operations, and receives the target broadcast signal according to the order of the priority levels from high to low, so as to obtain the target broadcast audio data.

For example, if a site announcer and a fire alarm are currently broadcasting, the mobile phone can select to preferentially receive the wireless broadcast signal sent by the fire alarm because the fire alarm is at the highest priority.

Further, in the embodiment of the present application, if there are multiple broadcast signals with the same priority, to avoid timing conflicts between the multiple broadcasts, the audio relay device may configure multiple antennas for receiving, that is, may be capable of receiving multiple wireless broadcast signals simultaneously to avoid timing conflicts between the multiple broadcast signals.

It should be understood that the audio relay apparatus may be configured with a plurality of receiving antennas, such as a first receiving antenna and a second receiving antenna, and the audio relay apparatus may receive a first wireless broadcast signal transmitted by the first broadcasting apparatus by using the first receiving antenna, and simultaneously receive a second wireless broadcast signal transmitted by the second broadcasting apparatus by using the second broadcasting apparatus, thereby avoiding a timing collision in signal reception between a plurality of broadcasts.

Further, in the embodiment of the present application, while the audio transmission system obtains the broadcast audio data through the audio relay device, the audio relay device may also detect whether it is currently outputting other non-broadcast audio data, that is, detect the current audio output state (102), and then execute the forwarding processing of the target broadcast audio data in combination with the current audio output state.

Therefore, in the application, the audio transmission system can execute the receiving process of the wireless broadcast signal according to the broadcast configuration information corresponding to the broadcast equipment, such as the encryption parameter, the broadcast signal receiving priority level and the like, through the audio relay equipment, and then decode the broadcast signal, and after the broadcast audio data is obtained, further forward the broadcast audio data to the audio output equipment through the audio relay equipment, so that the defect that the power consumption of the earphone is too large is overcome, the problem that the time sequence conflict exists between the broadcast audio data playing and the current audio playing is solved, and the intelligence of the audio relay equipment is high.

Based on the foregoing embodiment, in a further embodiment of the present application, fig. 11 is a schematic diagram illustrating an implementation flow of an audio transmission method proposed in the embodiment of the present application, as shown in fig. 11, in the embodiment of the present application, a method for an audio transmission system to obtain target broadcast audio data through an audio relay device (step 101) includes the following steps:

step 101c, after the audio transfer device establishes wireless communication connection with the audio output device, acquiring current broadcast audio data played by the broadcast device through a sound acquisition module, and detecting the current position state;

and step 101d, if the current position state is the target position, determining the current broadcast audio data as the target broadcast audio data.

It can be understood that, if the broadcasting device plays the broadcast audio data through the speaker or the loudspeaker, the audio transmission system may collect the broadcast audio data in real time through the sound collection module in the audio relay device, such as the microphone, and since the collected broadcast audio data are not all required by the user, the audio relay device may determine the target broadcast audio data that the user needs to listen to in combination with the current position state.

Specifically, the audio transmission system may detect the current position state in real time through the audio relay device, and if the current position state is the target position state, the audio relay device may determine the broadcast audio data collected by the microphone at this time as the target broadcast audio data, and further forward the target broadcast audio data to the audio output device, such as a bluetooth headset.

For example, when a passenger takes an airplane, a mobile phone can acquire real-time position information of the passenger through a WIFI signal in an airport or satellite positioning, and when the passenger is known to be located in the airport at present, the mobile phone collects boarding and broadcasting information of the airport through a microphone and forwards the boarding and broadcasting information to the passenger. In detail, the audio relay device may further combine with the passenger's target flight boarding information, and when it is known that the passenger is currently located in the airport and the collected boarding reminder is the user's target flight boarding reminder, the audio relay device may determine the collected current broadcast audio data as the target broadcast audio data, and further forward the target broadcast audio data to an audio output device, such as a bluetooth headset.

For example, when a passenger takes a subway, the mobile phone can acquire real-time position information of the passenger through a WIFI signal in the subway or satellite positioning, and when the passenger arrives at a certain station, the mobile phone can forward station broadcasting received by the microphone to the passenger with the Bluetooth headset.

Therefore, in the application, the audio transmission system can collect the broadcast audio data through the microphone in the audio transfer device and forward the broadcast audio data to the audio output device through the audio transfer device, so that the defect of overlarge power consumption of the earphone is overcome, the problem of time sequence conflict between the broadcast audio data and the current audio playing is solved, and the intelligence of the audio transfer device is high.

If the mobile phone is playing other audio data through the wireless earphone at present, the mobile phone can perform audio mixing processing on the broadcast audio data and other audio data, so that the broadcast audio data is emphasized in the audio data after audio mixing, and then the audio data after audio mixing is sent to the wireless earphone to enable a user to listen to the broadcast. If the mobile phone does not play other audio data through the wireless earphone currently, the mobile phone can directly send the broadcast audio data to the wireless earphone so as to enable the user to listen to the broadcast.

If the gateway in the living room plays other audio data through the sound box currently, the gateway can perform sound mixing processing on the broadcast audio data and other audio data first, so that the broadcast audio data are highlighted in the audio data after sound mixing, and then the audio data after sound mixing are sent to the sound box to enable a user to listen to the broadcast. If the gateway does not play other audio data currently through the stereo, the gateway can send the broadcast audio data directly to the stereo to enable the user to listen to the broadcast.
