The Origin and Development of Bluetooth Headphones
/kloc-in the 0/0 century, the Nordic princes fought for hegemony, and the Danish king stepped forward. With his unremitting efforts, the bloody war was stopped and all parties sat at the negotiating table. Through communication, the princes bridged their differences and became friends. Because the Danish king loves blueberries very much, and his teeth are dyed blue, he is called the king of Bluetooth, so Bluetooth has become synonymous with communication.
1000 years later, a new wireless communication standard came out, and people named it Bluetooth. 1995, Ericsson first proposed the concept of Bluetooth. Bluetooth profile works in microwave band, the transmission rate is 1m bytes per second, and the maximum transmission distance is 10m, which can be achieved by increasing the transmission power.
