Song Shiqiang on the technical route of Bluetooth headset (thirty-eight):

Song Shiqiang said I used to be an engineer by birth, and I have a natural sensitivity to technology. What is the Bluetooth (blue tooth) technology applied to headphones? It is a short-range communication technology, covering a range of 10 meters or less, and the meaning of the name is to compare it to a person's gold teeth, which are both precious and small in size. Bluetooth communication is characterized by point-to-point one-to-one mode, but in the headset application scenario, people have two ears, which brings the Bluetooth headset to solve the problem of synchronous playback of two points, that is, how to transmit a sound source to two headphones at the same time, this problem has not been solved on the lack of development, has been using wired headphones.

Later Apple solved this problem, the method is to first use the phone's Bluetooth (blue tooth) signal to activate a headset, and then use this headset and then send a signal to activate another headset, the middle process of a bit of a delay, the two headphones are not synchronized to boot, but the difference is only a few seconds, the human ear basically do not recognize, I Song Shiqiang that there is stereo effect. So the idea and technology breakthroughs let Apple grabbed the first opportunity. Later, our domestic constant string and Zhongke Lancel, Jerry, these TWS bluetooth headset main chip company is to learn this method, huawei, millet, oppo, etc. Immediately follow up. Our gold beacon at that time is to do some bluetooth headset ceramic antenna, and miniature charging connector, this product and the application of technology we kinghelm (www.kinghelm.com.cn) engineers in advance on in-depth research, but also with SLKOR (www.slkoric.com) of the mos tube and TVS tube sl3401, sl2n7002 to sell together, so our company in a wave also earned some money, this is the Bluetooth headset technology breakthrough route.

Later, the bluetooth headset market pattern has gradually evolved into, part of the authentic apple bluetooth headset, another part of the imitation apple bluetooth headset, this to Huaqiang north as the distribution center for the production and sales, the third part of the bluetooth headset is other domestic, they are generally with the domestic cell phone manufacturers technology synergies with huawei yu seung tung led by huawei cell phone, opo, millet, vivo and other cell phone pairing, because bluetooth headset Is dependent on the cell phone application.

This is the current market distribution of bluetooth headset! "Kinghelm" brand "KH" series of products, used in high-speed railroads, new energy vehicles, personal transportation, wireless intelligent terminals, Internet of things, smart cities, new infrastructure, smart home, industrial equipment, industrial Internet, medical, Scientific research, military industry, commercial aerospace and other fields. Under the leadership of Mr. Song Shi-Qiang, JASL strives to research new technologies and launch new products to contribute to the progress and development of the society!
