Introduction to Bluetooth speakers
Bluetooth is a low-cost and large-capacity short-range wireless communication specification. A Bluetooth laptop is a laptop with Bluetooth wireless communication capabilities. There is a legend about the name Bluetooth. In the 10th century AD, when the princes of Northern Europe fought for hegemony, the King of Denmark stepped forward. With his unremitting efforts, the bloody war was stopped and all parties sat at the negotiating table. Through communication, the princes relieved their suspicions and became friends. Because the king of Denmark loves to eat blueberries so much that his teeth are dyed blue, he is called the king of Bluetooth, so Bluetooth has become synonymous with communication. Today, a thousand years later, when a new wireless communication specification was introduced, people used Bluetooth to name it again.
In 1995, Ericsson first proposed the Bluetooth concept. The Bluetooth specification uses microwave frequency bands with a transmission rate of 1M bytes per second and a maximum transmission distance of 10 meters. The transmission power can be increased to 100 meters. Bluetooth technology is open globally and has good compatibility worldwide. The whole world can be connected through a low-cost invisible Bluetooth network.
Bluetooth technology is not only used in computers. Many electronic devices such as mobile phones, digital cameras, camcorders, printers, fax machines, home appliances, etc. can use Bluetooth technology to achieve wireless connectivity without having to drag a tail (connecting line). With the popularization of Bluetooth technology, you no longer have to worry about wiring electrical appliances when decorating your home; when using home appliances, you don’t have to worry about a lot of remote controls. You can do everything with a mobile phone or a car key. The company’s work arrangements and the pictures of family members at home can be obtained anytime and anywhere; there is no need to queue for check-in and payment, pass near the payment point, and can be easily completed without entering the door… The wide application of Bluetooth technology will make our life extremely easy.
