What is a Bluetooth speaker? Bluetooth speaker refers to rely on Bluetooth transmission  protocol (A2SP stereo protocol) information transmission speakers, bluntly speaking refers  to the "Bluetooth" technology in the traditional digital and multimedia speakers, so that users can remove the wire to tie him down, comfortable listen to music in various ways.

   Speaking of "Bluetooth" technology, will have to look at what "Bluetooth" is. "Bluetooth" is a short-range  communications device (10m inside) radio technology support. It uses microwave frequency band, the transmission  rate per Second 1M byte, the maximum transmission distance of 10 meters, can be achieved by increasing the transmit power of 100 meters, can include mobile phones, PDA, wireless headsets, laptops between computers, peripherals and  other related equipment for wireless signal Exchange of information. The use of "Bluetooth" technology, can effectively  simplify communication between mobile communication terminal equipment, which has become more rapid and efficient data  transmission, wireless communication widen the road. Since Bluetooth technology is full Ball open, plus it is a low-cost high-capacity short-range wireless communication standard, so Bluetooth technology (Bluetooth) wireless technology also  allows the speaker becomes possible.

   Bluetooth was first put forward by Ericsson, followed by a large number of Bluetooth applications, such as computers, mobile  phones, digital cameras, camcorders, printers, fax machines, home appliances and other electronic devices are many, especially  in 2011 after Bluetooth smart phones and Bluetooth tablet has been rapid development, both from all aspects of performance, screen,  etc. are amazing, but the affected volume and wires, speakers have no breakthrough in the development, and consumers because they have mastered the Bluetooth phone or Bluetooth tablet and other front-end equipment, for this part of the demand is growing. Bluetooth speakers homeopathic sky, portable way, wireless transmission, stylish look to get strong consumer favorite.

   Bluetooth speakers as a Bluetooth application, relative to other wireless speaker has its four unique features

   1,wide range of applications 
   Global harmonization of technical specifications Bluetooth mobile phone, PDA, wireless headsets, laptops, automotive, medical equipment, computer  peripherals and other equipment, As long as a Bluetooth adapter, you can easily connect a Bluetooth device for data transmission or voice communications,  widespread popularity, good compatibility. 
   2, easy to operate 
   Bluetooth technology is a real-time technology, it does not require fixed infrastructure, and easy installation and setup, no cables to connect, so  Very easy to use, simply complete the pairing can be put into use, lower operating threshold. 
   3, the transmission speed is faster 
   Compared to other methods such as infrared, Bluetooth protocol on speed has a clear advantage, Bluetooth 4.0 theoretical maximum speed of 24Mbps, faster  The speed can ensure higher quality, it has sufficient capacity to carry a higher bit rate music. 
   4, the transmission distance is moderate 
   Bluetooth transmission distance is generally less than 10 meters, just a room size, and can transmit data partition, very suitable for home environments

   Since Bluetooth protocol is not a free technology, the use of this technique for any vendor to the organization must pay a royalty, and this  Costs will be reflected in the cost of points, the current price is still higher than that of Bluetooth audio devices ordinary products. Above several Bluetooth speakers in the mainstream market, Overall quality of the music is good, the price close to the people most Microlab H21, Microlab H21 Bluetooth  module using the quality of the most stable of the British name factory CSR BC5 Chip, 2.1 + EDR (Enhanced data rate- rate enhancement technology) allows Bluetooth  transmission bandwidth of 2.1M, in order to achieve high-quality music Transmission. H21 Bluetooth search and access almost instantaneously, very fast. The most important is not how basically operating in the speaker end, just in their own hands Turn on the Bluetooth function on the machine or tablet, you can search for Microlab H21. Without  pairing code to connect. Thus Bluetooth speakers, as mature Bluetooth technology in an application, at the technical level and product realization terms, is likely to replace  traditional wired speakers.
