We are familiar with Bluetooth, two years ago we started using Bluetooth wireless transfer photos, music, share files, and Bluetooth headset hanging on the ear phone is also particularly Latin style. Today, these applications are not rare, and now almost every mobile phone, tablet comes with a Bluetooth module, Bluetooth applications but is more of a concern in new areas.

Bluetooth technology, plainly, is a short-range communications support equipment (10m inside) radio technology. We see more wireless technology, infrared earlier, 2.4G, Bluetooth more fire to the nearest, wifi wireless transmission can be done, the same wireless transmission of its use and application areas are not the same, depending on the their different characteristics.

As now, there are six versions of Bluetooth technology, including V1.1, 1.2,2.0,2.1,3.0,4.0, backward compatible with the high version, which V1.1, 1.2 version has been basically eliminated, this was undoubtedly the most widely used application surface V2.0, 2.1 version, the transmission rate of up to 2Mbps or more, and can transmit both data and voice. Although the latest improvements Stupid V3.0, 4.0 has been out, and significantly increased to 24Mbps, the theoretical value of the transmission distance is up to 60 meters in transmission speed, high-performance but also means large power consumption.

In addition, we will also see the word X version + EDR of the Bluetooth on the product packaging, "EDR" refers to what is it? "EDR" is in order to achieve high data traffic transmission while doing supplement form, it is the acronym for Enhanced data rate, meaning that the rate enhancement. With his supplementary, V2.1 version of Bluetooth rates up to 2.1M, but also do not have to consume power.

Because CD-quality data (44.1KHz sampling rate, 16bit sampling precision) valid audio data about 1.4Mbit, CD-quality music signal to be transmitted, the transmission rate is only maintained at 2Mbit / s can be achieved, while taking into account the Bluetooth speaker transmission power, Bluetooth "2.1 + EDR" version competent, and therefore also the mainstream market Bluetooth speaker version V2.1 + EDR majority.

Today, the PC market is gradually shrinking, a subsidiary of PC peripherals derivatives have also been greatly affected sales of traditional computer speakers representing a decrease of 68 percent more, but Bluetooth smart phones, tablet PC sales is a clear upward trend, increasing move to the front of the surrounding the demand for mobile accessories also increased significantly. While the front-end rich music class software category, also contributed to the increased desire for people to speakers. So last year became the Bluetooth speaker fast start of the year, this year has been aimed more brands Bluetooth speaker market, the Bluetooth as one of the new growth point.

Bluetooth speakers are not limited to portable speakers, computer speakers are also many traditional adds Bluetooth functionality on the basis of the original product. Compare Microlab FC-50 FC-50BT introduced this year edition, Yamaha ISX-B820 is also in the original ISX-800 adds Bluetooth. Therefore, a far cry from speakers ranging from the volume of use, quality of its price from three different fifty dollars to seven or eight thousand dollars.

Bluetooth speaker entourage just started last year, but the homogenization phenomenon has emerged. Some clever manufacturers have noticed this, and strive in the function and shape a new breakthrough, so we see in the market combined with Bluetooth and NFC technology, the speaker has "three" function, speakers pack-touch, dual-radio speaker series, and so novel.

Bluetooth speakers give new ideas is one of the major manufacturers brains trying to stand out in the market approach, the same Bluetooth portable speakers, and some called "outdoor speakers," some call it "social speaker", as well as with "appreciation class" speakers, and both are used in order to accelerate the pace of new concepts market segments, tight encirclement.

Any product can not escape the question:

Etekcity T12 Portable Wireless Rechargeable Bluetooth Speaker development less than two year, is also facing the problem can not be avoided. First, set aside a large computer speakers and home speakers aside, but in a portable Bluetooth speaker, the problem they face is how to maintain a longer battery life. The battery life of portable speaker phones and tablets preferably not less than the life, after all, such a function is that Bluetooth speakers traveling gatherings, bursts of power affect the atmosphere also affects mood, which is updated in every generation Bluetooth version is not Operators trying to get perfect.

Secondly, the theoretical value Bluetooth speaker transmission distance within 10 meters, the premise requires no obstacles, there are some limitations here. like the shower the next while listening to music, waterproof speakers broadcast music in the bathroom, the phone is not waterproof on the outside of the bathroom, but the bathroom is only separated by a wall, the music began to play off, can not help but feel disappointed. Of course, every kind of technology is not perfect, there are certain limitations on the basis of how to improve on the original, get a better user experience, and this is indeed a problem.

So Bluetooth will by virtue of its own technological advantage in audio circles to show its mettle, but Bluetooth speakers will certainly intensify competition.
