Description
Technical Field
The invention relates to the technical field of Bluetooth voice communication, in particular to a Bluetooth group talkback communication system and an implementation method thereof.
Background
The popularization of bluetooth technology and the support of voice make bluetooth application scenarios more and more. Bluetooth headsets are not only connected to one host but are also relayed to other bluetooth headsets, e.g. TWS technology. However, voice is also a mode of one bluetooth headset to one bluetooth host, and bluetooth group talkback cannot be realized.
Disclosure of Invention
Aiming at the defects in the prior art, the technical problem to be solved by the invention is to provide a Bluetooth group talkback communication system and an implementation method thereof, which are used for realizing multi-person talkback of Bluetooth voice equipment.
The technical scheme adopted by the invention for realizing the purpose is as follows: a Bluetooth group talkback communication system comprises a plurality of Bluetooth devices, wherein each Bluetooth device is at least connected with one other Bluetooth device through audio streams, the Bluetooth device initiating connection is used as a master node, the other Bluetooth devices connected with the plurality of Bluetooth devices are used as master and slave nodes, and the Bluetooth device connected with only one Bluetooth device is used as a slave node;
the slave node is used for sending the audio input by the slave node to the master node/master-slave node connected with the slave node, receiving the audio sent by the master node/master-slave node connected with the slave node and playing the audio;
the master node/the master-slave node is used for receiving and mixing audio transmitted by other Bluetooth equipment and playing the audio after mixing the audio; and sending mixed audio to any Bluetooth device connected with the Bluetooth device, wherein the mixed audio is the audio input by the Bluetooth device and the audio sent by other Bluetooth devices connected with the Bluetooth device.
The Bluetooth devices all comprise an earphone, a microphone and a Bluetooth transceiver.
A method for realizing a Bluetooth group talkback communication system comprises a plurality of Bluetooth devices, wherein each Bluetooth device is connected with at least one other Bluetooth device through audio streams, the Bluetooth device initiating connection is used as a master node, the other Bluetooth devices connected with the Bluetooth devices are used as master and slave nodes, and the Bluetooth device connected with only one Bluetooth device is used as a slave node;
for the slave nodes, the audio input by the slave nodes is sent to the master node/master-slave node connected with the slave nodes, and the audio sent by the master node/master-slave node connected with the slave nodes is received and played;
for the main node/the master-slave node, receiving and mixing audio transmitted by other Bluetooth equipment, and playing the audio after mixing; and sending mixed audio to any Bluetooth device connected with the Bluetooth device, wherein the mixed audio is the audio input by the Bluetooth device and the audio sent by other Bluetooth devices connected with the Bluetooth device.
The Bluetooth devices all comprise an earphone, a microphone and a Bluetooth transceiver.
The invention has the following advantages and beneficial effects:
1. the invention uses the tree network to transmit the broadcast data, avoids the generation of the ring, and can achieve the effect of broadcasting voice by using a simple flooding mechanism.
2. The voice of the invention is characterized by adopting audio mixing transmission, so that one voice stream can transmit a plurality of voices, the bandwidth is greatly saved, and the group Bluetooth intercommunication is realized.
3. Compared with the mode of independently transmitting each voice of each Bluetooth node to all other Bluetooth nodes, the method has obvious advantages.
Drawings
FIG. 1 is a schematic diagram of the system of the present invention;
fig. 2 is a schematic diagram of a voice mixing and forwarding method of a bluetooth node according to an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, one bluetooth device, as one bluetooth node, can support simultaneous connection of audio streams (SCO/eSCO) with multiple bluetooth nodes, each of which can transmit bi-directional voice. One bluetooth node can be used as a pure master node to connect 3 slave nodes. After being connected by the master node, the slave node can also be used as the master node to connect other slave nodes, namely, one node can simultaneously play a master-slave role. This supports the basic conditions for multiple networking talkbacks. Starting from the master node, it can grow as a tree structure.
The bluetooth device includes an earpiece, a microphone, and a bluetooth transceiver.
Realize speech transmission and relay through the network deployment between the bluetooth equipment for the audio mixing of the microphone of other bluetooth equipment in the group can both be sent out to the earphone of every bluetooth equipment, and every people who uses bluetooth equipment in the group can both hear other people's sound promptly.
When one bluetooth node is disconnected from the master node SCO due to distance, other master/slave nodes may discover and connect it. Discovery of nodes is not within the scope of this patent discussion, for example, BLE broadcasts may be utilized.
After a bluetooth node joins the network, no matter what role, the method of routing talkback voice is the same: an incoming voice is broadcast to the other ports, and the headset local to the node (Mic in fig. 2) also computes an audio.
As shown in fig. 2, taking one bluetooth device as a bluetooth node as an example, if the bluetooth node is connected with 3 SCO audio streams, the voice routing is as follows:
incoming audio from SCO1, sent to SCO2, SCO3 and speakers;
incoming audio from SCO2, sent to SCO1, SCO3 and speakers;
incoming audio from SCO3, sent to SCO1, SCO1 and speakers;
incoming audio from Mic is sent to SCO1, SCO2 and SCO 3.
Like this, the audio outlet of this bluetooth node all has many audio streams to send out, and the SCO only has one, and the method of sending out after many audio mixing of accessible just can realize the demand, sees the audio mixing from the delivery outlet direction, is exactly:
audio coming from SCO1, SCO2 and SCO3 is mixed and sent out from a loudspeaker;
audio coming from SCO2, SCO3 and Mic is mixed and then sent out from SCO 1;
audio coming from SCO1, SCO3 and Mic is mixed and then sent out from SCO 2;
incoming audio from SCO1, SCO2 and Mic is mixed and sent out from SCO 3.
After networking, the Mic input of any node is transferred to the output of other loudspeakers.
