[0002] Bluetooth technology is not only used in computers, but also in many electronic devices such as mobile phones, digital cameras, camcorders, printers, fax machines, home appliances, etc., to achieve wireless connectivity without having to drag a tail. With the popularization of Bluetooth technology, home decoration no longer requires worries about the wiring of electrical appliances. When using home appliances, there is no need to worry about a large number of remote controls. A mobile phone or a car key can handle everything. When you are away from home, you can get the company's work arrangements and the pictures of your family members at home anytime and anywhere. You don't have to queue up to punch in and pay fees. You can easily complete it by passing by the payment point without entering the door. The widespread application of Bluetooth technology will make our lives extremely easy. Bluetooth speakers refer to speakers with built-in Bluetooth chips that connect to Bluetooth. Replacing the traditional audio equipment connected by wires, it is connected to Bluetooth playback devices such as mobile phones, tablets and laptops to achieve the purpose of convenience and speed. Bluetooth speakers are mainly portable speakers, and their appearance is generally small and portable. Bluetooth speaker technology is gradually valued and accepted by consumers due to its convenience. Most common Bluetooth speakers on the market are mono speakers, and some multi-channel speakers with excellent sound quality have also emerged. Bluetooth speakers apply Bluetooth technology to traditional digital and multimedia speakers, allowing users to avoid the entanglement of annoying wires and listen to music freely in various ways. Since the advent of Bluetooth speakers, with the development of smart terminals, they have received widespread attention from users such as mobile phones and tablets. Bluetooth technology makes wireless speakers possible.

[0003] For example, the patent document with announcement number CN 112272417 B discloses a dual Bluetooth speaker reconnection method and a display device. After the display device is restarted, a connection is established with a first Bluetooth speaker. When the connection status information of the first Bluetooth speaker fed back by the Bluetooth protocol stack is received, a connection with the second Bluetooth speaker is started. This application realizes the reconnection of dual Bluetooth speakers under the DualAudio mechanism, and can reduce the timing conflict when the dual Bluetooth speakers are reconnected, ensuring that both Bluetooth speakers can be effectively reconnected, thereby improving the user experience under the DualAudio mechanism.
