In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Referring to fig. 2, fig. 2 is a flowchart illustrating a BLE-based audio sharing method according to a first embodiment of the present invention. In this embodiment, the audio sharing method includes the steps of:
step S10, when a target slave that scans a broadcast signal sent by a BLE master exists in a plurality of slaves, the target slave is connected to the BLE master and receives an audio data packet sent by the BLE master;
the audio sharing method based on BLE in this embodiment is applied to a system composed of a BLE master and a plurality of slaves, the BLE master is a hardware terminal which can receive raw audio data and transmit the processed data as broadcast signals, the hardware terminal has a receiving port for connecting terminals such as a computer and a network television, and can transmit the broadcast signals to use BLE for communication connection after the slave scans, and the slaves are a pair of bluetooth earphones. The BLE host and the slave are both provided with a BLE (Bluetooth Low Energy) module for supporting the communication connection, and the BLE host and the slave are in communication connection through the BLE so as to realize the function of sharing the audio of the BLE host to the slaves.
Further, the slave machine comprises a receiving antenna module which is used for scanning the broadcast signals sent by the BLE host machine; the slave machine also comprises a display screen which is applied to the display of the earphone information and the sending message. The BLE host machine sends the broadcast signals to the plurality of slave machines based on preset broadcast intervals by using a sending antenna module arranged in the BLE host machine; the channels transmitted therein are preset by the bluetooth protocol, preferably 37, 38 and 39 channels. The plurality of slaves scan in 37, 38 and 39 channels specified by the Bluetooth protocol based on the receiving antenna module arranged in the slaves; in addition, the broadcast signal transmitted by the BLE host carries a BLE host device name, which can be identified by a device identification flag, such as the device identification flag a. After the plurality of slave machines start scanning, whether the slave machines scan the broadcast signals carrying the BLE host machine name containing the equipment identification mark A or not is judged, and when the slave machines scan the broadcast signals carrying the BLE host machine name containing the equipment identification mark A, the slave machines scanning the broadcast signals are judged as target slave machines. The target slave displays the BLE host equipment name containing the equipment identification mark A on a display screen so as to enable a user to select the equipment name. When receiving a connection request instruction sent by a user selection device name, the target slave machine establishes connection with the BLE host machine and receives audio data sent by the BLE host machine.
Step S20, the target slave computer decompresses the audio data packet based on a preset mode and a preset proportion to generate audio data;
furthermore, audio codecs are arranged in both the BLE master and the target slave, and are respectively used for compressing received audio data and decompressing audio data packets. The Audio codec may be an OPUS Audio codec or an AAC (Advanced Audio Coding) Audio codec, but the OPUS codec has lower damage to Audio data during compression compared to the AAC Audio codec, and can make the Audio data decompressed from the Audio data packet closer to the original Audio data, so the embodiment is preferably an OPUS Audio codec mode. In addition, the preset ratio for compression and decompression is set in advance according to the requirement, and the preset ratio can be nine to one, ten to one, eleven to one and the like, and the embodiment is preferably ten to one because the ten to one ratio generates better benefit in the compression and decompression process than other ratios.
Understandably, in order to ensure the integrity of the target slave computer for decompressing the audio data packet, before decompressing according to the preset mode and the preset proportion, whether the target slave computer completes the reception of the audio data packet is judged, and if the target slave computer completes the reception, the target slave computer performs decompression. Specifically, when decompressing the received audio data packet, the OPUS audio codec calls the preset ratio to decompress the audio data packet by the preset ratio, and generates audio data that can be played.
Step S30, the target slave machine plays the audio data;
furthermore, the target slave machine is provided with a built-in power amplifier module for playing audio data. In addition, the target slave is also provided with a control switch module, specifically, the control switch module comprises a button switch, when the button switch is pressed, the playing of the audio data is paused, and when the button switch is pressed in the paused state, the playing of the audio data is resumed, so as to realize the control of the playing state of the audio data.
Furthermore, in order to realize better audio playing, the target slave computer is also provided with an audio processor module so as to process the audio data decompressed by the audio codec through input gain control, input equalization adjustment, input end delay adjustment, input polarity conversion and the like, so as to obtain higher playing tone quality, and a user has better listening experience.
In this embodiment, after one or more slaves individually scan the broadcast signal transmitted by the BLE master, the slave scanned with the broadcast signal is determined as a target slave, and the target slave is connected to the BLE master and receives the audio data packet. After the target slave is connected to the BLE host, the audio data packet is decompressed and the audio data is played in a preset mode and proportion, and therefore the purpose that the BLE host is directly connected in a scanning mode without pairing is achieved, and the playing audio data is obtained. Meanwhile, a plurality of target slave machines can be simultaneously connected with the BLE host machine to play audio data, and audio sharing is achieved. In addition, the target slave and the BLE host are in communication connection through BLE, and the power consumption of the target slave is lower than that of a TWS (two way communication) headset or a classic Bluetooth headset.
Further, referring to fig. 3, a second embodiment of the BLE-based audio sharing method according to the present invention is provided based on the first embodiment of the BLE-based audio sharing method according to the present invention, in which the step of the target slave connecting to the BLE host and receiving the audio data packet sent by the BLE host includes:
step S11, the target slave machine displays a device name corresponding to the preset mark on a display screen of the target slave machine, wherein the device name is the name of the BLE master machine;
in step S12, when the target slave receives the connection request command transmitted based on the displayed device name, the target slave establishes a connection with the BLE master and receives the audio data packet transmitted by the BLE master.
In this embodiment, when the broadcast signal is scanned, the target slave displays a device name with a preset mark on the display screen, where the device name is a name set by the BLE master, so that the user can select the device name through the display screen, and send a connection request command to connect the target slave to the BLE master. And the target slave establishes connection with the BLE host and receives the audio data packet once receiving the connection request command sent by the user selection. It should be noted that the target slave includes a left earphone and a right earphone, and the BLE master can be connected to the target slave independently, so that when the target slave receives a connection request command sent based on the displayed device name, the step of establishing the connection between the target slave and the BLE master includes:
step S121, when the target slave machine receives a connection request instruction sent based on the displayed equipment name, judging the earphone attribute in the connection request instruction;
step S122, if the earphone attribute in the connection request instruction is a left ear attribute, establishing the connection between the left earphone and the BLE host;
step S123, if the earphone attribute in the connection request instruction is a right ear attribute, establishing a connection between the right earphone and the BLE host.
Further, the target slave includes a left earphone and a right earphone, both of which are provided with earphone attributes, specifically, the left earphone attribute includes an asserted flag L of the left earphone, and the right earphone attribute includes a asserted flag R of the right earphone. When the target slave receives a connection request instruction transmitted based on the displayed device name, the earphone attribute in the connection request instruction is judged. If the earphone attribute in the connection request instruction contains the identification mark L of the left earphone, establishing the connection between the left earphone and the BLE host; and if the earphone attribute in the connection request instruction contains the identification mark R of the right earphone, establishing the connection between the right earphone and the BLE host. After the target slave machine is connected with the BLE host machine, the left earphone and the right earphone in the target slave machine respectively display an icon L and an icon R which indicate that the connection with the BLE host machine is established on the display screen.
Further, after the connection is established, the target slave machine acquires the address of the BLE host machine, and the subsequent target slave machine only receives the audio data packet sent by the BLE host machine in a broadcast signal through the address; when the BLE master reads and receives the updated audio data from the terminal equipment, the target slave automatically receives the updated audio data packet.
In this embodiment, the left and right earphones of the slave are separately connected to the BLE host, and in order to ensure that the right and left earphones have selected the correct attribute, the user may select the attribute information having the earphone identification flag, thereby realizing the same frequency of the right and left earphones; specifically, when a connection request instruction sent based on the displayed device name is received, the headset attribute in the connection request instruction of the target slave is judged, so that the BLE host can accurately connect to the left headset and the right headset. After the connection with the BLE host is established, the target slave acquires the address of the BLE host, and then only receives the audio data packet sent by the BLE host through the address, wherein the audio data packet is sent by the broadcast signal, so that the phenomenon of repeatedly scanning and receiving is avoided.
Further, referring to fig. 4, fig. 4 is a flowchart illustrating a BLE-based audio sharing method according to a third embodiment of the present invention. In this embodiment, the audio sharing method includes the steps of:
step S40, when the BLE host receives an original audio, compressing the original audio into an audio data packet based on a preset mode and a preset proportion;
in this embodiment, a receiving port is set in the BLE host, the BLE host is connected with a terminal device such as a computer and a network television through the receiving port, and is configured to read and receive original audio data in the terminal device, and after the BLE host completes receiving work of the original audio data, the BLE host compresses the received original audio data in a preset proportion by using an OPUS audio codec set in the BLE host, so as to generate an audio data packet.
Step S50, the BLE master sends the audio data packet to a plurality of slaves;
the BLE host comprises a sending antenna module, and is particularly applied to sending broadcast signals; the BLE host machine sends broadcast signals to a plurality of slave machines in channels 37, 38 and 39 specified by a Bluetooth protocol by using a sending antenna module arranged on the BLE host machine based on a preset broadcast interval, wherein the broadcast signals consist of audio data packets and BLE host machine equipment names containing FLAG marks convenient for a user to identify, so that the slave machines scan the broadcast signals in the channels at different time, receive the audio data packets and realize sharing.
In this embodiment, when the BLE host receives the original audio data, the original audio data is compressed into audio data packets at a preset ratio based on the OPUS codec; the BLE host sends the audio data packets to the plurality of slaves in the form of broadcast signals, and low-power transmission of the BLE-based audio sharing system is achieved. The BLE host sends the audio data packet to the plurality of slaves, and the plurality of slaves can be connected with the BLE host at the same time to play the audio data.
Referring to fig. 5, fig. 5 is a first embodiment and a second embodiment of a BLE-based audio sharing method according to the present invention, and a fourth embodiment of the BLE-based audio sharing method according to the present invention is proposed, in which to ensure the safety of the operation, a security verification mechanism is introduced, and the execution of the security verification mechanism includes the following:

Judging the awakening instruction sent by the display screen based on the target slave again after judging that the execution main body is a conductor, and if the awakening instruction is continuously executed for two times within 2 seconds or is continuously executed for more than or equal to 3 seconds, executing the awakening instruction for awakening the display screen; otherwise, the received awakening instruction is determined to be false touch operation, and the awakening instruction is refused to be executed.
And a manager information input interface for identifying a manager is arranged in the target slave machine. When a user enters a manager information entry interface of the target slave machine for the first time, the target slave machine displays information for prompting the user to perform fingerprint entry on a display screen; after receiving a first fingerprint input operation instruction of a user, displaying information for reminding the user to perform fingerprint input again on a display screen, and when receiving a second fingerprint input operation instruction of the user, identifying the user as a manager of the target slave computer. In the subsequent use process, in order to prevent the occurrence of a malicious behavior of disconnecting the target slave machine from the BLE host machine, which is executed by a non-administrator, when the target slave machine receives a disconnection instruction for disconnecting the target slave machine from the BLE host machine, which is displayed and sent on the basis of a display screen, whether a user sending the instruction is the administrator is judged, specifically, the fingerprint attribution of the user is judged, and if the fingerprint attribution of the user is the administrator, the disconnection instruction is executed to disconnect the target slave machine from the BLE host machine; otherwise, the disconnection instruction is refused to be executed.
Further, when the target slave machine receives an instruction selected and sent by a user, the time length for executing the instruction is judged, if the time length for executing the instruction is more than or equal to 8 seconds, the shutdown instruction is executed, otherwise, the instruction selected and sent by the user based on the display screen is executed.
