Recently, Xinyu Intelligence developed the first fully automatic vacuum packaging line for Bluetooth battery cells in China, which greatly promotes the battery production efficiency of electronic products such as Bluetooth earphones. Since our equipment is closely related to Bluetooth technology, let's talk about the past and present of Bluetooth together, and make everyone fall in love with this practical technology even more.

Bluetooth technology was first proposed and implemented by Swedish telecommunications giant Ericsson, which had business dealings with China since the late Qing Dynasty.

The term "Bluetooth" is an anglicized version of Bl å tand/Bl å tann in Scandinavian language (i.e. bl á t ǫ nn in Old Norwegian), which refers to a 10th century king named Harald ▪ The nickname of Bluetooth, he unified the warring Danish tribes into one kingdom, and is said to have introduced Christianity. The idea of naming Bluetooth after this was originally proposed by Jim Kardach in 1997, who developed a system that allowed mobile phones to communicate with computers. His inspiration came from the historical novel The Long Ships, written by Frans G. Bengtsson and depicting the Vikings and the Harald Bluetooth King, which he was reading at the time, suggesting that Bluetooth would also unify communication protocols into a global standard.

Nowadays, Bluetooth is managed by the Bluetooth Special Interest Group (SIG). The Bluetooth Technology Alliance has over 25000 member companies worldwide, distributed in multiple fields related to our lives such as telecommunications, computers, networks, and consumer electronics, making life more convenient. These have indeed fulfilled his original intention.

If there is no built-in Bluetooth on the computer, only a USB dongle is needed. If there is, simply turn it on to transfer data,. In the early days, adapters were needed to connect devices one by one.

Bluetooth has been around for more than 20 years and has produced numerous versions, including version 4.2, which has been continuously optimized to solve some difficulties encountered by manufacturers in product interoperability. It has reduced energy consumption and link loss of earphones during transmission, as well as the strength of wireless circuits when transmitting large amounts of data. The new version covers all old versions.

And the reason why Bluetooth is so powerful is that it adapts to different devices and situations through the Bluetooth protocol stack and numerous sub protocols under the Bluetooth protocol, as well as ensuring successful and exclusive data transmission through baseband error correction and connection settings.

As for health concerns and interference with Bluetooth. The maximum output power of the former is not as good as the minimum output power of the mobile phone, which can be ignored; The latter can increase the distance between USB 3.0 devices and other Bluetooth devices, or provide simple solutions such as purchasing USB cables with better shielding performance. Other solutions include additional shielding of Bluetooth components in the computer.

Fortunately, Bluetooth also has numerous awards, such as the Bluetooth Innovation World Cup set up by the Bluetooth Technology Alliance, which aims to encourage the innovative development of Bluetooth low-power wireless technology in global sports, fitness, and healthcare products, stimulate new markets, and the generous rewards are very inspiring.

In summary, Bluetooth, a highly legendary thing, will undoubtedly provide deeper and broader services in future production and life as technology improves. And as we focus our energy on this related equipment, Xinyu Intelligence is bound to occupy a larger share of the lithium battery market cake in the future. Diversification will definitely give us a strong presence.
