BEST MODE FOR CARRYING OUT THE INVENTION

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIG. 1, an embodiment of the present invention provides a method for controlling a split wireless audio device, including the following steps:

S10. The first wireless audio sub-device receives a control instruction.

S20. Adjust an operating state of the first wireless audio sub-device according to the control instruction, and send the control command to a second wireless audio sub-pair paired with the first wireless audio sub-device through a low-power wireless channel. And a device to adjust an operating state of the second wireless audio sub-device.

In this embodiment, the split wireless audio device includes two or more than two wireless audio sub-devices. The split wireless audio device can be a TWS split Bluetooth headset or a split wireless Bluetooth speaker. Unlike other wireless audio devices, each wireless audio sub-device needs to enter a low-power state that can receive commands, rather than a power-off state.

The control method for implementing the split type wireless audio device of the present invention requires the following premise: each wireless audio sub-device has completed pairing. The working state of the wireless audio sub-device includes two types, a power-on state and a low power state. In the power-on state, a high-power wireless channel and a low-power wireless channel are established between each wireless audio sub-device. High-power wireless channels are mainly used for the transmission of audio data. Low-power wireless channels are mainly used to control the transfer of instructions. In low power states, wireless audio sub-devices only retain low-power wireless channels. In a low-power wireless channel, the wireless audio sub-device only retains the receiving function, and the wireless audio sub-device can consume less than 10 microamps.

In step S10, the first wireless audio sub-device refers to a wireless audio sub-device that receives a control command. Taking the TWS split Bluetooth headset as an example, the TWS split Bluetooth headset includes a left ear headset and a right ear headset. The first wireless audio sub-device may be a left ear earphone or a right ear earphone. The control command may be generated by externally pressing a button of the first wireless audio sub-device, or may be sent by a smart terminal paired with the first wireless audio sub-device. Here, the control command is mainly used to adjust the working state of the wireless audio sub-device.

In step S20, one of the roles played by the first wireless audio sub-device is mainly to forward the control command. In the power-on state, the first wireless audio sub-device directly transmits a control command to the second wireless audio sub-device with which it is paired. If the first wireless audio sub-device is paired with more than one wireless audio sub-device, the first wireless audio sub-device may also send a control command to the third wireless audio sub-device or the fourth wireless audio sub-device with which it is paired. The second wireless audio sub-device receiving the control command adjusts its working state according to the control instruction.

When the first wireless audio sub-device sends the control instruction, it also adjusts its working state according to the control instruction. Taking the device as an example, the first wireless audio sub-device enters a low-power state from the power-on state.

Optionally, step S10 includes:

In this embodiment, the control instruction includes a shutdown command. The shutdown command is used to adjust the wireless audio sub-device from the power-on state to the low-power state, that is, after the wireless audio sub-device receives the shutdown command, it does not actually shut down, but enters a low-power state. In the low power state, the wireless audio sub-device can keep connected with the mobile phone or other devices at a very low frequency (such as 0.5S/time); or only has the receiving function, and the power consumption is lower, and the BLE is within 10us. Can only be woken up by physical buttons. It should be noted that, when any one of the wireless audio sub-devices receives the power-on command, the command is sent to the other wireless audio sub-device at a higher frequency, so that the other wireless audio sub-device receives the power-on command in time. The control command is generated by pressing a button on the first wireless audio sub-device, and may also be referred to as a button command. A specific key operation mode can be preset as a control command. For example, "long press the switch button for 3 seconds" as the "power on/off" control command. When the working state of the first wireless audio sub-device is the power-on state, the first wireless audio sub-device receives the shutdown command by pressing and pressing the switch button for 3 seconds.

Optionally, the adjusting the working state of the first wireless audio sub-device according to the control instruction includes:

In this embodiment, when the shutdown command is triggered, the first wireless audio sub-device is adjusted from the working state to the low power consumption state. At this time, the first wireless audio sub-device turns off all functions except the receiving function of the low-power channel, thereby minimizing power consumption.

Optionally, step S10 includes:

In this embodiment, the control command includes a power-on command. The power-on command is used to adjust the wireless audio sub-device from a low-power state to a power-on state. The control command is generated by pressing a button on the first wireless audio sub-device, and may also be referred to as a button command. A specific key operation mode can be preset as a control command. For example, "long press the switch button for 3 seconds" as the "power on/off" control command. When the working state of the first wireless audio sub-device is a low power consumption state, the first wireless audio sub-device receives the power-on command by long pressing the switch button for 3 seconds.

In this embodiment, when the power-on command is triggered, the first wireless audio sub-device is adjusted from the low power consumption state to the working state. At this time, the first wireless audio sub-device returns to a normal working state, and all functions of the first wireless audio sub-device can be realized.

Optionally, if the control instruction is a power-on command, step S20 includes:

The full name of A2DP is the Advanced Audio Distribution Profile Bluetooth Audio Transmission Model Agreement. A2DP defines ACL (Asynchronous Protocols and procedures for transmitting high quality audio information such as mono or stereo over a Connectionless asynchronous connectionless channel. After the A2DP communication channel is enabled, audio data can be transmitted between the first wireless audio sub-device and the paired smart terminal and the second wireless audio sub-device, thereby implementing the function of wirelessly playing audio. At this time, the working state of the first wireless audio sub-device is adjusted from a low power state to a power-on state.

Optionally, if the control instruction is a shutdown command, step S20 includes:

In this embodiment, when the control command is a shutdown command, the working state of the first wireless audio sub-device is adjusted from a power-on state to a low-power state. The first wireless audio sub-device turns off the A2DP communication channel. Similarly, the operating state of the second wireless audio sub-device is also adjusted from the power-on state to the low power state. The second wireless audio sub-device turns off the A2DP communication channel. This can greatly reduce the power consumption of the first wireless audio sub-device and the second wireless audio sub-device, and improve their endurance.

Optionally, the low power wireless channel includes a BLE communication channel or a WiFi communication channel.

Bluetooth Low Energy (BLE) technology is a low-cost, short-range, interoperable, robust wireless technology that operates at license-free 2.4GHz ISM RF band. Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN), typically using a 2.4G UHF or 5G SHF ISM radio frequency band. The first wireless audio sub-device can transmit a control command to the second wireless audio sub-device in one of two ways.

The control method of the split type wireless audio device provided by the invention establishes a low power wireless channel between the wireless audio sub-devices and shares the switching machine command. In this way, any wireless audio sub-device can be turned on and off without affecting the power consumption of the system, so that the other wireless audio sub-devices paired with it can respond to the same switch operation without manually turning on each wireless. Audio sub-devices greatly enhance the user experience.
