Please refer to FIG. 4 , which is a schematic flowchart of a method for selecting a Bluetooth connection of a multiplayer device provided by an embodiment of the present invention. The method includes the following steps:

Step S101, when the control terminal is connected to the main playback device in the multi-player device through wireless fidelity Wi-Fi, the main playback device obtains the Wi-Fi of each playback device in the control terminal and the multi-player device. -Fi signal strength value.

A playback system composed of multiple playback devices will form a private network, such as a MESH network, through which each playback device can exchange control information and playback data. In the private network of the playback system, at least one playback device is connected to the router, for example, connected to the router by wired or wireless means. This playback device is called the main playback device of the playback system, and other playback devices are called slave playback devices. . The main playback device is the bridge connecting the playback system with external devices, and also the control core of the entire playback system. On the one hand, through the main playback device, the playback system can access the Internet and local area network, and can obtain playback data from the Internet and local area network for playback. On the other hand, each control terminal (such as a smartphone) connected to the playback system is actually the main playback device connected to the playback system. The main playback device receives control commands from the control terminal to coordinate and control the work of the entire playback system. And return the status information of the playback system and each playback device to the control terminal. The master playback device and other slave devices in the playback system exchange control commands and status information through the private network, and the master playback device can realize synchronous playback of multiple playback devices through these control commands and status information.

Of course, the slave playback device is also connected to the router, because the master and slave playback devices of the playback system are relative, and the relationship between the master and slave sometimes changes, so the slave playback device also needs to be connected to the router.

The control terminal and each playback device are connected to the router, and the control terminal and each playback device can detect their own Wi-Fi signal strength values, and send the detected Wi-Fi signal strength values to the main playback device. Since the distance between the control terminal and each playback device is different from the router, their Wi-Fi signal strength values may also be different.

Step S102, the main playback device selects the Wi-Fi connection with the control terminal among the plurality of playback devices according to the Wi-Fi signal strength value of each playback device in the control terminal and the multi-player device. At least one first playback device with the closest signal strength value.

The main playback device can locate the control terminal and each playback device according to the Wi-Fi signal strength value of the control terminal and each playback device. The playback device closest to the Wi-Fi signal strength value of the control terminal is also the space away from the control terminal. closest.

Screening the playback device according to the Wi-Fi signal strength value facilitates the user to select the Bluetooth playback device on the control terminal.

Step S103, the main playback device sends a connection instruction to the selected at least one first playback device, the connection instruction is used to instruct the at least one first playback device to turn on the bluetooth module, through the bluetooth module and the The control terminal performs Bluetooth communication.

Select the playback device closest to the control terminal for Bluetooth communication, and transmit playback data through Bluetooth, which can improve the signal quality of Bluetooth transmission.

According to a method for selecting a Bluetooth connection of a multi-playback device provided in an embodiment of the present invention, the one or the closest to the Wi-Fi signal strength value of the control terminal is selected according to the Wi-Fi signal strength values of the control terminal and each playback device. Multiple playback devices perform Bluetooth communication between the control terminal and the playback devices, which facilitates the user to select playback devices on the control terminal, and improves the Bluetooth transmission quality between the control terminal and the playback devices.

Please refer to FIG. 5 , which is a schematic flowchart of another method for selecting a Bluetooth connection of a multiplayer device according to an embodiment of the present invention. The method includes the following steps:

Step S201, the main playback device periodically acquires the Wi-Fi signal strength value of the wireless router connected to the main playback device detected by the control terminal and each playback device in the multi-player device.

When a smart terminal is connected to the playback system through the Wi-Fi wireless network (that is, connected to the playback system through the control software on the smart terminal), the smart terminal will periodically (for example, every 10 seconds) transmit the Wi-Fi signal detected by itself Intensity value, sent to the main playback device of the playback system. Similarly, each playback device in the playback system will also periodically send the value of the Wi-Fi signal strength detected by itself to the main playback device of the playback system. The smart terminal and the playback device should detect the Wi-Fi signal strength value of the same wireless router.

Step S202, the main playback device compares the Wi-Fi signal strength value of each playback device in the multi-player device with the Wi-Fi signal strength value of the control terminal.

Step S203, the main playback device selects at least one first playback device whose Wi-Fi signal strength value difference between the control terminal and each playback device in the multi-player device is the same, as the control terminal and the control terminal. The playback device whose Wi-Fi signal strength value is closest to the terminal.

Step S204, the main playback device sends a connection instruction to the selected at least one first playback device, the connection instruction is used to instruct the at least one first playback device to turn on the bluetooth module, through the bluetooth module and the The control terminal performs Bluetooth communication.

The main playback device of the playback system, among all the playback devices, searches for at least one playback device with the Wi-Fi signal strength value closest to it for the smart terminal, and turns on the bluetooth module of the playback device. The smart terminal can be connected with the playback device via bluetooth to play music. If the Wi-Fi signal strength values of two or more playback devices are similar to those of the smart terminal, the Bluetooth modules of these playback devices can be turned on at the same time, and the user can choose one of them to connect; or the playback system can choose one of them to turn on the Bluetooth module.

For example: There are 6 playback devices in a playback system. In a certain period, the Wi-Fi signal strength values detected by them are as follows:

There is a smart terminal connected to the playback system, and the Wi-Fi signal strength value of the smart terminal is -29dBm. Then, the playback system finds for the smart terminal a playback device whose Wi-Fi signal strength value is closest to it—player device 2. Thus, the playback system turns on the bluetooth module of the playback device 2 and turns off the bluetooth modules of other playback devices. On the one hand, the user can only see and select one playback device in the Bluetooth device selection list; on the other hand, because the Wi-Fi signal strength of this playback device is closest to the Wi-Fi signal strength of the smart terminal , they are most likely in the same area and the closest, so when they use Bluetooth to transfer music data, they can get the best transfer quality. After the playback device 2 receives the audio data transmitted by the smart terminal through Bluetooth, it will also distribute it to the other 5 playback devices through the private network of the playback system, so that the 6 playback devices in the entire playback system can play music synchronously.

Step S205, if the main playback device detects that the playback device closest to the Wi-Fi signal strength value of the control terminal has changed, and the main playback device detects that the control terminal and the at least one first The playback device is transmitting data, and detecting whether the data transmission is completed.

Step S206, if it is detected that the data transmission is completed, the main playback device sends a disconnection instruction to the at least one first playback device.

Step S207, the main playback device sends the connection instruction to the at least one second playback device, and the connection instruction is used to instruct the at least one second playback device to turn on the Bluetooth module.

When the user's smart terminal moves, the detected Wi-Fi signal strength will change, and the smart terminal periodically sends the detected Wi-Fi signal strength value to the main playback device of the playback system. The main playback device of the playback system will search for the playback device with the closest Wi-Fi signal strength for the smart terminal. However, if the smart terminal is transmitting audio and playing music to the playback system through Bluetooth, the playback system will not turn on and off the Bluetooth module of the playback device, and will still keep the Bluetooth module of the original playback device turned on, so that music playback will not be interrupted . When the smart terminal interrupts the playback, the playback system completes the bluetooth startup and shutdown actions of the playback device, and notifies the smart terminal to switch to a new playback device to connect to the bluetooth.

According to a method for selecting a Bluetooth connection of a multi-playback device provided in an embodiment of the present invention, the one or the closest to the Wi-Fi signal strength value of the control terminal is selected according to the Wi-Fi signal strength values of the control terminal and each playback device. Multiple playback devices perform Bluetooth communication between the control terminal and the playback device, which can facilitate the user to select the playback device on the control terminal, and improve the quality of Bluetooth transmission between the control terminal and the playback device; and the hand-held control terminal When the user's location changes, it can automatically switch to a playback device with a better Bluetooth signal.
