Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Referring to fig. 2, fig. 2 is a flow chart of 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 machine which scans a broadcast signal sent by a BLE host machine exists in a plurality of slave machines, the target slave machine is connected with the BLE host machine and receives an audio data packet sent by the BLE host machine;
the audio sharing method based on BLE in this embodiment is applied to a system composed of a BLE host and a plurality of slaves, where the BLE host is a hardware terminal that can receive original audio data and transmit the data in a broadcast signal after processing, the hardware terminal has a receiving port for connecting terminals such as a computer and a network television, and can transmit the broadcast signal to use BLE for communication connection after the slaves scan, and the slaves are a pair of bluetooth headphones. The BLE host computer and the slaves are both provided with BLE (Bluetooth Low Energy, bluetooth low power consumption) modules for supporting the communication connection, and the BLE host computer and the slaves are in communication connection through BLE, so that the function of sharing the audio of the BLE host computer among the slaves is achieved.
Further, the slave comprises a receiving antenna module, which is used for scanning the broadcast signal sent by the BLE host; the slave also comprises a display screen which is applied to the display of the earphone information and the sent message. The BLE host computer uses a transmitting antenna module arranged inside the BLE host computer to transmit broadcast signals to a plurality of slaves based on a preset broadcast interval; wherein the channel transmitted is preset by the bluetooth protocol, preferably 37, 38 and 39 channels. A plurality of slaves scan in 37, 38 and 39 channels specified by the Bluetooth protocol based on internally arranged receiving antenna modules; in addition, the broadcast signal sent by the BLE host carries a BLE host device name, which can be identified by a device identification flag, such as device identification flag a. After a plurality of slaves start scanning, judging whether a broadcast signal scanned by the slaves to the name of the BLE host computer equipment containing the equipment identification mark A exists in the slaves, and when the fact that the slaves scan to the broadcast signal carrying the name of the BLE host computer equipment containing the equipment identification mark A exists is detected, judging the slaves scanned to the broadcast signal as target slaves. The target slave displays the BLE host machine equipment name containing the equipment identification mark A on a display screen so that a user can select the equipment name. When receiving a connection request instruction sent by a user selecting a device name, the target slave establishes connection with the BLE host and receives audio data sent by the BLE host.
Step S20, the target slave machine decompresses the audio data packet based on a preset mode and a preset proportion to generate audio data;
furthermore, the BLE host and the target slave are both provided with audio codecs, which are respectively applied to compress the received audio data and decompress the audio data packets. The audio codec may be an OPUS audio codec, or may be an AAC (Advanced Audio Coding ) audio codec, but compared to an AAC audio codec, the OPUS codec has a lower damage degree to audio data during compression, and can make the audio data decompressed from the audio data packet more similar to the original audio data, so that the OPUS audio codec is preferred in this embodiment. In addition, the preset ratio for compression and decompression is set in advance according to the requirement, and may be nine-to-one, ten-to-one, eleven-to-one, etc., and the present embodiment is preferably ten-to-one because the ten-to-one ratio produces better benefits in the compression and decompression process than the other ratios.
It is understandable that, in order to ensure the integrity of the target slave to decompress the audio data packet, before decompressing according to the preset mode and the preset proportion, it is determined whether the receiving of the audio data packet is completed, and if the receiving is completed, the decompression is performed. Specifically, when the OPUS audio codec decompresses the received audio data packet, the preset ratio is called to decompress the audio data packet by the preset ratio, so as to generate audio data that can be played.
Step S30, the target slave plays the audio data;
further, the target slave is provided with a built-in power amplifier module for playing the audio data. In addition, the target slave machine 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, when the button switch is pressed in the paused state, the playing of the audio data is resumed, and the playing state of the audio data is controlled.
Furthermore, in order to realize better audio playing, the target slave is further provided with an audio processor module, so that the audio data decompressed by the audio codec is processed by input gain control, input equalization adjustment, input end delay adjustment, input polarity conversion and the like, and higher playing tone quality is obtained, so that a user has better listening experience.
In this embodiment, after one or more slaves scan a broadcast signal sent by a BLE master, the slaves that scan the broadcast signal are determined as target slaves, and the target slaves connect to the BLE master and receive audio packets. 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, so that the situation that the BLE host is directly connected in a scanning mode without pairing to obtain the played audio data is realized. Meanwhile, a plurality of target slaves can be connected with the BLE master at the same time to play audio data, so that audio sharing is realized. 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 TWS earphone or classical Bluetooth earphone.
Further, referring to fig. 3, a first embodiment of a BLE-based audio sharing method according to the present invention is provided, in which the target slave is connected to the BLE host, and the step of receiving an audio data packet sent by the BLE host includes:
step S11, the target slave displays a device name corresponding to the preset mark on a display screen of the target slave, wherein the device name is the name of the BLE host;
in step S12, when the target slave receives the connection request instruction sent based on the displayed device name, the connection between the target slave and the BLE host is established, and an audio data packet sent by the BLE host is received.
In this embodiment, when a broadcast signal is scanned, the target slave displays the device name with the preset flag on the display screen, where the device name is the name set by the BLE host, so that the user can select the device name through display on the display screen, and send a connection request instruction to connect the target slave and the BLE host. And once the target slave receives a connection request instruction selected to be sent by a user, establishing connection with the BLE host and receiving an audio data packet. It should be noted that, the target slave includes a left earphone and a right earphone, and can be connected with the BLE host independently, so that when the target slave receives a connection request instruction sent based on the displayed device name, the step of establishing connection between the target slave and the BLE host includes:
step S121, when the target slave 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 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 connection between the right earphone and the BLE host.
Further, the left earphone and the right earphone included in the target slave are both provided with earphone attributes, specifically, the left earphone attribute contains a recognition mark L of the left earphone, and the right earphone attribute contains a right earphone recognition mark R. And when the target slave receives a connection request instruction sent based on the displayed equipment name, judging the earphone attribute in the connection request instruction. If the earphone attribute in the connection request instruction contains a recognition mark L of the left earphone, establishing connection between the left earphone and the BLE host; if the earphone attribute in the connection request instruction contains the identification mark R of the right earphone, the connection between the right earphone and the BLE host is established. After the target slave establishes a connection with the BLE host, the left earphone and the right earphone in the target slave will display an icon L and an icon R on the display screen, respectively, indicating that a connection has been established with the BLE host.
Further, after connection is established, the target slave acquires the address of the BLE host, and the subsequent target slave only receives an audio data packet sent by the BLE host through the address in a broadcast signal; when the BLE host reads and receives updated audio data from the terminal device, the target slave will automatically receive updated audio data packets.
In the embodiment, the left earphone and the right earphone of the slave are respectively and independently connected with the BLE host, so that in order to ensure that the right earphone and the left earphone have selected correct attributes, a user can select attribute information with earphone identification marks, and the same frequency of the right earphone and the left earphone is realized; specifically, when a connection request instruction sent based on a displayed device name is received, the earphone attribute in the connection request instruction of the target slave is judged, so that the BLE host can accurately connect to the left earphone and the right earphone. After connection with the BLE host is established, the target slave acquires the address of the BLE host, and only the audio data packet sent by the BLE host through broadcast signals is received through the address, so that repeated scanning and receiving actions are avoided.
Further, referring to fig. 4, fig. 4 is a flow chart of 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 the original audio, the original audio is compressed 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 used for reading and receiving original audio data in the terminal device, after the BLE host completes the receiving work of the original audio data, the received original audio data is compressed by using an OPUS audio codec set by the BLE host according to a preset proportion, and an audio data packet is generated.
Step S50, the BLE host transmits the audio data packet to a plurality of slaves;
the BLE host includes a transmitting antenna module, specifically, applied to transmitting broadcast signals; based on a preset broadcast interval, the BLE host uses a transmitting antenna module arranged by the BLE host to transmit broadcast signals to a plurality of slaves in 37, 38 and 39 channels specified by a Bluetooth protocol, wherein the broadcast signals consist of audio data packets and BLE host equipment names containing FLAG marks which are convenient for users to identify, so that the slaves scan the broadcast signals in the channels at different times, 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 an audio data packet according to a preset ratio based on an OPUS codec; the BLE host transmits the audio data packet to a plurality of slaves in the form of a broadcast signal, so that low-power transmission of the BLE-based audio sharing system is realized. The BLE host transmits the audio data packet to a plurality of slaves, and the slaves can be simultaneously connected with the BLE host 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 security of operation, a security verification mechanism is introduced, and the execution of the security verification mechanism includes the following:

After the execution main body is judged to be a conductor, judging the wake-up instruction sent by the display screen of the target slave machine again, and executing the wake-up instruction for waking up the display screen if the wake-up instruction is continuously executed twice within 2 seconds or continuously executed for 3 seconds or more; otherwise, the received wake-up instruction is determined to be the false touch operation, and execution of the wake-up instruction is refused.
The target slave is internally provided with an administrator information input interface for identifying an administrator. When a user enters the manager information input interface of the target slave machine for the first time, the target slave machine displays information prompting the user to input fingerprints on a display screen; after the first fingerprint input operation instruction of the user is received, information for reminding the user to input the fingerprint again is displayed on a display screen, and when the second fingerprint input operation instruction of the user is received, the user is identified as a manager of the target slave machine. In the subsequent use process, in order to prevent the malicious disconnection of the target slave machine and the BLE host machine, which are executed by a non-manager, when the target slave machine receives a disconnection instruction for connecting the target slave machine and the BLE host machine based on the display screen display, judging whether a user sending the instruction is a manager, specifically judging that the fingerprint of the user belongs to the user, if the fingerprint of the user belongs to the manager, executing the disconnection instruction, and disconnecting the target slave machine and the BLE host machine; otherwise, refusing to execute the disconnection instruction.
