[0002] Bluetooth technology is not only used in computers, but also used in many electronic devices such as mobile phones, digital cameras, camcorders, printers, faxes, household appliances and the like, so that wireless connection can be achieved without dragging a tail. With the popularization of Bluetooth technology, people no longer need to worry about the wiring of electrical appliances during home decoration, and people no longer need to worry about a large number of remote controllers when using household appliances. One mobile phone or one car key can solve all problems. When going out, people can obtain the arrangement of work in the company and the picture of family members at any time and any place. People can easily complete the payment without queuing up, and can easily complete the payment without entering the door when passing by the payment point. The wide application of Bluetooth technology will make people's life much easier. Bluetooth speakers refer to sound equipment with built-in Bluetooth chips, which replace traditional wire connection with Bluetooth connection.
