Description

A kind of wireless bluetooth earphone, master-slave switching optimization method of wireless bluetooth earphone

technical field

The invention relates to the technical field of bluetooth earphone communication, in particular to a wireless bluetooth earphone and a master-slave switching optimization method for the wireless bluetooth earphone.

Background technique

Bluetooth headset is to apply Bluetooth technology to hands-free headsets, so that users can avoid annoying wires and talk easily in various ways. Since the advent of Bluetooth headsets, it has been a good tool for mobile business families to improve efficiency.

Existing wireless Bluetooth headsets often need to connect multiple devices or connect multiple Bluetooth devices to the same terminal, and need to face different and complex environments.

For example, the application number is CN201910182235.X, a wireless bluetooth headset, a wireless bluetooth headset master-slave switching optimization method. The method includes the following method steps: when an external event triggers master-slave switching, the first Bluetooth earphone sends a first switching instruction to the second Bluetooth earphone through the second Bluetooth link, and the second Bluetooth earphone receives the first switching instruction. The link returns the first confirmation instruction to the first Bluetooth headset, the first Bluetooth headset sends the Bluetooth upper layer status information to the second Bluetooth headset through the second Bluetooth link, and the first Bluetooth headset keeps receiving the audio data sent by the smart device.

However, when the master-slave earphones are switched, a dual-channel Bluetooth device is used, which greatly increases the power consumption of the Bluetooth device during work and switching, and worsens the battery life of other Bluetooth devices that have a short standby time. .

Therefore, the present invention provides a wireless bluetooth headset and a master-slave switching optimization method for the wireless bluetooth headset to solve the problems raised in the background technology above.

When the A012 channel is working, the B02 channel remains open. If a new Bluetooth signal appears, it is called the insertion signal for short. For example, the No. 1 Bluetooth headset is identified by the B02 channel and sends a receiving command to the B01 channel , the B01 channel records the inserted signal and connects, and obtains the node information in the A03 channel. After the No. 2 Bluetooth headset is disconnected from the ear, the signal connection is disconnected, and after the No. 1 Bluetooth headset is placed in the ear, from the acquisition node, Start the output of the audio signal to switch the master and slave earphones. At the same time, the master and slave channels are switched, A02 becomes the slave channel, and A01 is the master channel.

As a further solution of the present invention: the new bluetooth signal is called an insertion signal, that is, a new bluetooth device.

As a further solution of the present invention: the coprocessor is provided with an auxiliary channel A03, and the A03 channel is opened after the main channel is opened, and the A03 channel is used to create a node under the current main channel mode, and record node information, and feed back to from the channel.

As a further solution of the present invention: the No. 1 Bluetooth headset and the No. 2 Bluetooth headset are collectively referred to as Bluetooth devices, and ear canal detection devices are provided on the headsets.

Compared with prior art, the beneficial effect of the present invention is:

In the present invention, a bluetooth chip and a coprocessor are provided, the bluetooth chip is provided with two main channels of A01 and A02, and two secondary channels of B01 and B02 are set in A01, and the coprocessor is provided with the A03 channel for creating and processing nodes , to achieve seamless switching between multiple Bluetooth devices without increasing the power consumption of Bluetooth devices, improving the convenience of switching while ensuring battery life.
