In the embodiment of the present application, a data transmission method is provided, which is used for transmitting audio data in the data transmission system. The electronic device can receive audio data sent by other electronic devices and send the audio data to the bluetooth headset 600 connected with the electronic device; the electronic device may also receive audio data transmitted by the bluetooth headset 600 connected to its bluetooth and transmit it to other electronic devices. The embodiment of the present application mainly takes the first electronic device 400a as an example for description.
The data transmission method, the data transmission apparatus, the electronic device 400, and the storage medium provided in the embodiments of the present application will be described in detail below with specific embodiments.
Referring to fig. 4, in the data transmission method, audio data is transmitted between a first electronic device 400a, a second electronic device 400b and a plurality of bluetooth headsets 600. Specifically, the method comprises the following steps:
step S110: the first electronic device 400a receives the audio data transmitted by the second electronic device 400 b.
The second electronic device 400b may transmit audio data to the first electronic device 400 a. The source of the audio data is not limited, and may be, for example, audio data into which voice information inputted by voice is converted, audio data stored inside the second electrical device, audio data downloaded from a server, or the like. The second electronic device 400b transmits the audio data to the first electronic device 400a through the network.
The first electronic device 400a receives audio data transmitted by the second electronic device 400 b.
Step S120: the first electronic device 400a sends the audio data to the plurality of bluetooth headsets 600 through bluetooth connection, respectively.
When receiving the audio data transmitted by the second electronic device 400b, the first electronic device 400a transmits the audio data to the plurality of bluetooth headsets 600 connected by bluetooth. Therefore, under the condition that the plurality of bluetooth earphones 600 receive the audio data, the voices corresponding to the audio data can be played, and users corresponding to the bluetooth earphones 600 can hear the voice information.
Step S130: the first electronic device 400a receives the audio data corresponding to the voice information collected by the plurality of bluetooth headsets 600, mixes the simultaneously received audio data, and sends the mixed audio data to the second electronic device 400 b.
In addition, any one of the bluetooth headsets 600 can collect voice information through the audio collection unit and convert the voice information into audio data. For example, a user inputs voice through a microphone of the bluetooth headset 600, and the bluetooth headset 600 collects the voice information and converts the voice information into audio data. The acquisition and conversion process is not limited in the embodiments of the present application, for example, sound is converted into a series of signals with voltage changes by a microphone, and the signals are converted into digitized audio data by sampling.
When receiving the voice information, each bluetooth headset 600 converts the voice information into audio data and transmits the audio data to the first electronic device 400a connected to the bluetooth headset.
If one of the plurality of bluetooth headsets 600 transmits audio data to the first electronic device 400a, the first electronic device 400a may transmit the audio data to the second electronic device 400b through the network.
If two or more bluetooth headsets 600 of the plurality of bluetooth headsets 600 transmit audio data to the first electronic device 400a at the same time. When receiving audio data of more than one bluetooth headset 600, the first electronic device 400a mixes the simultaneously received audio data and then transmits the mixed audio data to the second electronic device 400 b.
The specific manner of mixing the audio data of the different bluetooth headsets 600 in the first electronic device 400a is not limited. For example, the audio data may be obtained by superimposing sampling values at the same time in the simultaneously received audio data.
Specifically, the mixed audio data may be defined as mixed audio data. When receiving the plurality of audio data, the first electronic device 400a superimposes the sample values of the sounds at the same time in the plurality of audio data, and obtains the sample value corresponding to the time in the mixed audio data. For example, the electronic device receives the first audio data, the second audio data, and the third audio data corresponding to the three bluetooth headsets 600 at the same time, and superimposes the sampling values of the sounds at the same time in the first audio data, the second audio data, and the third audio data to obtain the sampling value corresponding to the time in the mixed audio data corresponding to the first audio data, the second audio data, and the third audio data.
It is to be understood that if not every audio data has a sample value at a certain time, the sample value corresponding to the time in the mixed audio data may be a superposition of the sample values of the audio data having the sample value at the time.
The first electronic device 400a then transmits the mixed audio data to the second electronic device 400 b.
In the embodiment of the present application, the first electronic device 400a may receive the audio data transmitted by the second electronic device 400b and send the audio data to the bluetooth headset 600 connected to the bluetooth, or may send the audio data collected by the bluetooth headset 600 and sent to the first electronic device 400a to the second electronic device 400 b. In this scheme, the first electronic device 400a enables the bluetooth headset 600 to communicate with the second electronic device 400b even if the first electronic device is located at a far end, so that the transmission mode of the bluetooth data is enriched.
In this embodiment, the first electronic device 400a may determine the bluetooth headset 600 performing data interaction among the plurality of bluetooth headsets 600 according to an actual situation when performing the audio data transmission of the bluetooth headset 600 to the second electronic device 400b and the audio data transmission of the second electronic device 400b to the bluetooth headset 600. Specifically, referring to fig. 5, the method may include:
step S210: the first electronic device 400a establishes bluetooth connections with a plurality of bluetooth headsets 600.
The first electronic device 400a may establish connections with a plurality of bluetooth headsets 600. The electronic device may include a plurality of bluetooth modules, and the electronic device may be connected to the plurality of bluetooth headsets 600 through each bluetooth module.
Optionally, before the electronic device is connected to the bluetooth headset 600, a bluetooth headset 600 queue may be set, and the bluetooth headset 600 in the bluetooth headset 600 queue allows the connection so as to control the connection permission.
When the bluetooth headset 600 initiates a pairing request to the electronic device, the electronic device may carry its own identity, and receive the pairing request of the bluetooth headset 600. When receiving the pairing request, the electronic device determines whether the identity carried by the pairing request is in a preset identity queue, where each identity in the preset identity queue is an identity of each bluetooth headset 600 in a preset bluetooth headset 600 queue.
If the identity carried in the pairing request is in the identity queue, the bluetooth headset 600 corresponding to the pairing request establishes a bluetooth connection. If the identity carried in the pairing request is not in the identity queue, it indicates that the bluetooth headset 600 corresponding to the identity does not have the permission for the audio data transmission, and the bluetooth headset 600 corresponding to the identity is rejected from establishing the bluetooth connection.
Step S220: the first electronic device 400a receives the audio data transmitted by the second electronic device 400 b.
In the data interaction process between the electronic devices, the first electronic device 400a may receive audio data transmitted by the second electronic device 400 b.
For one embodiment, the second electronic device 400b may be connected to a plurality of bluetooth headsets 600 as shown in fig. 2. The second electronic device 400b receives the audio data transmitted from the bluetooth headset 600 connected to the bluetooth and transmits the audio data to the first electronic device 400 a.
As an embodiment, the second electronic device 400b may also include an audio capturing unit, such as a microphone. The second electronic device 400b collects voice information input by the user through the audio collection unit, and converts the voice information into audio data. The second electronic device 400b transmits the obtained audio data to the first electronic device 400 a.
Step S230: the first electronic device 400a sends the audio data to the plurality of bluetooth headsets 600 through bluetooth connection, respectively.
The first electronic device 400a transmits the received audio data to the bluetooth headset 600.
If the number of the second electronic devices 400b is one, the first electronic device 400a receives audio data of one electronic device and sends the audio data to the bluetooth headset 600.
If the second electronic device 400b includes a plurality of devices, the first electronic device 400a may mix audio data transmitted by the second electronic devices 400 b. That is, if the first electronic device 400a simultaneously receives audio data transmitted by two or more second electronic devices 400b, the simultaneously received audio data are mixed. The manner in which the first electronic device 400a mixes the audio data of the multiple second electronic devices 400b is not limited in the embodiment of the present application, for example, as described above, the sampling values at the same time in different audio data are overlapped to obtain the sampling value corresponding to the time in the mixed audio data.
The first electronic device 400a then sends the mixed audio data to the plurality of bluetooth headsets 600 through bluetooth connection, respectively.
As an implementation manner, in the embodiment of the present application, the first electronic device 400a simultaneously distributes the received audio data to the respective bluetooth headsets 600.
As an implementation manner, the data transmission method provided in the embodiment of the present application may further include transmission of private data. That is, the first electronic device 400a may receive only audio data that is intended for one or more bluetooth headsets 600. Accordingly, the first electronic device 400a may transmit audio data intended for only one or more bluetooth headsets 600 only to the corresponding bluetooth headset 600.
Specifically, when the second electronic device 400b transmits audio data, the audio data may include sub-audio data carrying the identity of the bluetooth headset 600.
For example, as an embodiment, when the user inputs voice through the second electronic device 400b, the second electronic device 400b displays the respective bluetooth headsets 600 to which the first electronic device 400a is currently connected. The user can select the bluetooth headset 600 that wants to transmit voice in the second electronic device 400b and perform voice input. The voice input may be directly through the second electronic device 400b or through a bluetooth headset 600 that is bluetooth connected to the second electronic device 400 b. The electronic device carries the identity of the bluetooth headset 600 selected by the user in the audio data generated corresponding to the voice information.
For another example, as another embodiment, a private information button is provided in the bluetooth headset 600 bluetooth-connected to the second electronic device 400b, and the user can select the bluetooth headset 600 to which the voice information is to be sent through the private information button. The manner of selecting through the private information key is not limited, for example, pressing once corresponds to one determined bluetooth headset 600, pressing twice corresponds to another determined bluetooth headset 600, pressing three times corresponds to one determined bluetooth headset 600, and the like. After the user selects the bluetooth headset 600 connected to the first electronic device 400a through the private information key, when the bluetooth headset 600 corresponding to the private information key converts the received voice information into audio data, the audio data carries the identity of the selected bluetooth headset 600.
In this embodiment, when the second electronic device 400b receives the audio data of the plurality of bluetooth headsets 600, if the audio data of one of the bluetooth headsets 600 carries the identity of the bluetooth headset 600 to be transmitted, the audio data is not mixed with other audio data.
The second electronic device 400b transmits the received audio data to the first electronic device 400 a.
The first electronic device 400a receives the audio data sent by the second electronic device 400b, and determines whether the audio data includes sub-audio data carrying the identity of the bluetooth headset 600. That is, the first electronic device 400a determines whether a part of the audio data corresponds to the id of the bluetooth headset 600 in the received audio data.
If the sub audio data carrying the identification of the bluetooth headset 600 exists, the sub audio data is sent to the bluetooth headset 600 corresponding to the identification of the bluetooth headset 600, and other audio data in the received audio data is sent to the bluetooth headsets 600 other than the bluetooth headset 600 corresponding to the identification of the bluetooth headset 600. For example, the audio data received by the first electronic device 400a includes sub-audio data a and sub-audio data b, where the sub-audio data b is the sub-audio data b that does not carry the identity of the bluetooth headset 600 except the sub-audio data a in the audio data. The first electronic device 400a sends the sub-audio data a to the bluetooth headset 600 corresponding to the bluetooth headset 600 identity carried in the sub-audio data a, and distributes the sub-audio data b to other bluetooth headsets 600. Of course, the sub-audio data b may also be transmitted to all bluetooth connected bluetooth headsets 600.
Step S240: the first electronic device 400a receives audio data corresponding to the voice information collected by the plurality of bluetooth headsets 600, and determines whether to start the voice transmission permission of each bluetooth headset 600.
The user of the bluetooth headset 600 connected to the first electronic device 400a may also communicate with the second electronic device 400b through the first electronic device 400a, or communicate with the user of the bluetooth headset 600 corresponding to the second electronic device 400 b.
Specifically, each bluetooth headset 600 connected to the first electronic device 400a via bluetooth collects external voice information, converts the external voice information into audio data, and sends the audio data to the first electronic device 400 a. The first electronic device 400a receives the audio data corresponding to the voice information collected by the plurality of bluetooth headsets 600, mixes the simultaneously received audio data, and sends the mixed audio data to the second electronic device 400 b.
Optionally, in this embodiment of the application, the voice transmission authority of each bluetooth headset 600 bluetooth-connected to the first electronic device 400a may also be controlled. For example, if it is necessary to stop the transmission of the audio data of one or more bluetooth headsets 600 so that the audio data of these bluetooth headsets 600 will not interfere with the listening of the second electronic device 400b, the voice transmission permission of these bluetooth headsets 600 is turned off.
As an embodiment, the voice transmission authority of the bluetooth headset 600 may be turned off at the bluetooth headset 600 side. For example, the bluetooth headset 600 is provided with a voice transmission closing key, and the user closes the voice transmission permission of the bluetooth headset 600 through the touch of the key.
As an embodiment, the voice transmission authority of the bluetooth headset 600 may be turned off by the first electronic device 400 a. For example, after the bluetooth headset 600 to be turned off is selected in the first electronic device 400a, the voice transmission right of the bluetooth headset 600 is selected to be turned off.
When the first electronic device 400a receives the audio data sent by the bluetooth headset 600, it is determined whether the bluetooth headset 600 sending the audio data has the voice transmission permission.
Step S250: and mixing the audio data of the bluetooth headset 600 with the voice transmission permission turned on, and sending the audio data to the second electronic device 400 b.
If the voice transmission right of the bluetooth headset 600 is not closed, that is, the voice transmission right is opened, the audio data of the bluetooth headset 600 is sent to the second electronic device 400 b.
If the audio data of the plurality of bluetooth headsets 600 are received simultaneously and the determination result indicates that the voice transmission permission of more than one bluetooth headset 600 is not closed, the audio data corresponding to each bluetooth headset 600 with the voice transmission permission is mixed and then sent to the second electronic device 400 b.
Optionally, in this embodiment of the application, if the voice transmission permission of the bluetooth headset 600 is closed at the end of the bluetooth headset 600, the bluetooth headset 600 may not collect the voice information, that is, the bluetooth headset 600 that closes the voice transmission permission may not transmit the audio data to the second electronic device 400 b.
Step S260: and returning prompt information to the Bluetooth headset 600 which does not start the voice transmission permission for prompting that no voice transmission permission exists.
If the first electronic device 400a determines that the received audio data sent by the bluetooth headset 600 includes the bluetooth headset 600 corresponding to the audio data without the voice transmission permission, the first electronic device 400a does not speak the audio data corresponding to the bluetooth headset 600 and sends the audio data to the second electronic device 400 b.
Optionally, the first electronic device 400a may further return a prompt message to the bluetooth headset 600 that does not turn on the voice transmission permission, so as to prompt that the bluetooth headset 600 does not have the voice transmission permission. The prompt message may be audio data, and the bluetooth headset 600 that receives the audio data plays the audio data, so that the user knows that the bluetooth headset 600 has no voice transmission permission through the play of the bluetooth headset 600.
Optionally, when it is determined that the bluetooth headset 600 corresponding to the audio data does not have the voice transmission permission, the first electronic device 400a may determine which device the voice transmission permission of the bluetooth headset 600 is turned off by. If the voice transmission permission of the bluetooth headset 600 is closed at the bluetooth headset 600 end, the user generally knows that the bluetooth headset 600 has no voice transmission permission, and may not send the prompt message to the bluetooth headset 600. If the voice transmission permission of the bluetooth headset 600 is closed at the first electronic device 400a, a voice prompt message is sent to the bluetooth headset 600.
In this embodiment of the application, the sequence of receiving the audio data sent by the bluetooth headset 600 by the first electronic device 400a and receiving the audio data sent by the second electronic device 400b is not limited, and may be based on the actual receiving sequence.
In this embodiment, after receiving the audio data sent by the second electronic device 400b, the first electronic device 400a sends the audio data to each bluetooth headset 600. After receiving the audio data sent to each bluetooth headset 600, the first electronic device 400a determines whether to send the audio data to the second electronic device 400b according to whether the voice transmission permission of each bluetooth headset 600 is on, and controls the voice transmission permission of each bluetooth headset 600.
The data transmission method provided by the embodiment of the application can be applied to a multi-person conversation scene, and the multi-person conversation scene can be a remote conversation. For example, the first electronic device 400a and the second electronic device 400b are respectively used as two ends in a conversation scene, the first electronic device 400a is defined as a first end of the conversation scene, and the second electronic device 400b is defined as a second end of the conversation scene. Of course, if the number of the second electronic devices 400b is multiple, the multi-person conversation scene is not limited to two ends, each electronic device may serve as one end, each end sends audio data to other conversation ends, and each end may also receive audio data sent by other conversation ends. The present application mainly uses the number of the second electronic devices 400b as one for explanation.
The first electronic device 400a and the second electronic device 400b may be connected to one, two, or more than two bluetooth headsets 600, respectively. A user at a first end of the session scenario wears a bluetooth headset 600 bluetooth connected to the first electronic device 400a and a user at a second end of the session scenario wears a bluetooth headset 600 bluetooth connected to the second electronic device 400 b. The bluetooth headset 600 at each end may be divided into a plurality of groups, each group being configured to be worn by a user. One bluetooth headset 600 may be a group, or two bluetooth headsets 600 may be a group. If one bluetooth is a group, different bluetooth headsets 600 are used for different users to wear; if two bluetooth headsets 600 are in one group, then two bluetooth headsets 600 of each group are intended to be worn by the same user. Since each set of bluetooth headsets 600 is configured to be worn by one user, the same set of bluetooth headsets 600 are controlled in unison. For convenience of description, in the embodiment of the present application, each set of bluetooth headsets 600 is described as one bluetooth headset 600. The use of the data transmission system in a specific session scenario is described below by way of example.
In this session scenario, a session group may be established first. For example, the user creates a new session group at the first electronic device 400a, joins therein the respective bluetooth headsets 600 allowed to enter the session group, and the respective bluetooth headsets 600 in the session group are worn by the user referring to the session.
The joining method of joining the bluetooth headset 600 to the session group may be inputting the identity information of the bluetooth headset 600, or selecting the bluetooth headset 600 from the historical connection data, or selecting the bluetooth headset 600 to be joined to the session group from the self identity information broadcast by each bluetooth headset 600.
When the first electronic device 400a receives the pairing request of the bluetooth headset 600, if the bluetooth headset 600 is the bluetooth headset 600 in the conversation group, the bluetooth connection is established with the bluetooth headset 600, so that the bluetooth connection is established with each bluetooth headset 600 in the conversation group.
After the bluetooth connection of the bluetooth headset 600 is completed and the network connection between the first electronic device 400a and the second electronic device 400b is completed, the session may be started. In the session, if each user at the first end has a speech, the audio acquisition unit of the bluetooth headset 600 worn by the user can acquire speech information of the speech, convert the speech information into audio data, and send the audio data to the first electronic device 400 a.
The first electronic device 400a mixes the simultaneously received audio data and transmits the mixed audio data to the second electronic device 400 b. The second electronic device 400b transmits the received audio data to the respective bluetooth headsets 600 of the second end. Each bluetooth headset 600 at the second end decodes and plays the audio data, so that each user at the second end can hear the speech of each user at the first end through the bluetooth headset 600. If there are users speaking at the same time at the first end, each user at the second end can hear the voice of the users speaking at the same time and play the voice at the same time.
In the session, if only a certain user at the first end is required to speak, the voice transmission permission of the bluetooth headset 600 corresponding to other users except the user may be closed. Therefore, only the bluetooth headset 600 worn by the user who is allowed to speak collects voice information, converts the voice information into audio data, and transmits the audio data to the second electronic device 400 b. And other users do not transmit the sound to the second electronic device 400b through the bluetooth headset 600 worn by the other users even though the other users carelessly emit the sound, thereby reducing the voice noise transmitted to the second electronic device 400 b. Of course, the second end may also turn off all or part of the voice transmission authority of the bluetooth headset 600 in case of a need, so as to reduce the transmission of unnecessary voice noise.
In addition, the bluetooth headset 600 that closes the voice transmission permission can also open its voice transmission permission as required. The open mode may correspond to the closed mode, either through the bluetooth headset 600 itself or through the first electronic device 400 a.
During the session, the user at the second end may also send information separately to a certain user at the first end.
Specifically, the user at the second end selects the bluetooth headset 600 to be sent through the headset worn by the user or through the second electronic device 400b, and the selected bluetooth headset 600 is the bluetooth headset 600 at the first end. When the user at the second end speaks, the voice information is collected by the corresponding bluetooth headset 600, converted into audio data, and then transmitted to the second electronic device 400 b. The second electronic device 400b adds the identity of the bluetooth headset 600 to the audio data, where the identity is the identity of the selected bluetooth headset 600. The second electronic device 400b then sends the audio data carrying the id to the first electronic device 400 a.
After receiving the audio data, the first electronic device 400a sends the audio data corresponding to the identification to the bluetooth headset 600 corresponding to the identification, but not to other bluetooth headsets 600. The bluetooth headset 600 corresponding to the identity identifier plays the audio data, so that the user of the bluetooth headset 600 can know corresponding voice information without revealing the voice information to other users. Thereby realizing that the user at the second end transmits information to some users at the first end.
The data transmission method provided by the embodiment of the application can be used for audio data transmission in a multi-person conversation scene. When a user at one end of the session inputs voice through the bluetooth headset 600, the bluetooth headset 600 sends audio data corresponding to the voice to the first electronic device 400 a. The first electronic device 400a mixes the audio data received at the same time and transmits the mixed audio data to the second electronic device 400b, and the second electronic device 400b receives the audio data and transmits the audio data to the bluetooth headsets 600 connected thereto. Similarly, the second electronic device 400b may also receive audio data transmitted by each bluetooth headset 600, send the audio data to the first electronic device 400a, and the audio data is sent by the first electronic device 400a to each bluetooth headset 600 connected thereto for playing.
