Various electronic equipments such as electricity can use Bluetooth technology, wireless communications be realized, without dragging a tail（Connecting line）.
Universal with Bluetooth technology, when house decoration, is no longer worried for the wiring of electric appliance；When using household electrical appliances, it is not necessary to be a lot of distant
Control device and headache, a mobile phone or once all are settled automobile key energy；It is away from home, the job placement of company and family
The picture of relatives can obtain whenever and wherever possible；It checks card, pay the fees without being lined up, nearby pass through from payment point, it is not necessary to enter
Being easily accomplished ... the extensive use of Bluetooth technology will make our life incomparably light.
Different with other wireless sound boxes, Baffle Box of Bluetooth has the characteristics that its uniqueness：
1, it is widely used
The Bluetooth specification whole world is unified, mobile phone, PDA, wireless headset, laptop, automobile, Medical Devices, computer
Numerous equipment such as peripheral hardware can easily connect bluetooth equipment as long as possessing Bluetooth adapter, carry out data transmission or voice is logical
Letter, widely available, good compatibility.
2, easy to operate
Bluetooth technology is an instant technology, it does not require fixed infrastructure, and is easily installed and is arranged, and does not need cable
Connection can be realized, very easy to use, only need to be accomplished in a simple pairing can come into operation, and operation threshold is relatively low.
3, transmission speed is very fast
Compared to the other modes such as infrared, Bluetooth transmission protocol has apparent advantage, the theoretical most high speed of bluetooth 4.0 in speed
Degree reaches 24Mbps, and faster speed ensures that higher sound quality, it is made to have enough ability carrying higher sounds of code check
It is happy.
4, transmission range is moderate
The transmission range of bluetooth is generally within 10 meters, the size in exactly one room, and can partition wall transmission data, it is very suitable
Habitat environment uses of the whole family.
Existing Baffle Box of Bluetooth is merely possible to general speaker and uses, and there is no carry out visualization atmosphere according to music to dry
The function of support, user experience do not reach best.
