1:  Bluetooth Speaker Introduction

Bluetooth speaker refers to a built-in Bluetooth chip to connect Bluetooth audio devices to replace traditional wire connected via Bluetooth connection with mobile phones and other playback devices, to achieve the purpose of convenience. Currently, portable Bluetooth speaker to speaker and speaker-based micro desktop 2.0, 2.1, shape generally more compact and portable, Bluetooth speaker technology with its convenient user-friendly  features gradually being valued and accepted by consumers.

   2: Bluetooth Speaker features

   1, wide range of applications. Global harmonization of technical specifications Bluetooth mobile phone, PDA, wireless headsets, laptops, automotive,  medicalequipment, computer peripherals and other devices, as long as a Bluetooth adapter, you can easily Connecting 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, easy to use, simply complete the pairing can be Put into use, lower operating threshold. 
   3, the transmission speed. Compared to other methods such as infrared, Bluetooth protocol on speed has a clear advantage, Bluetooth 4.0 theoretical maximum  speed of 24Mbps, faster speed can ensure higher quality, It has sufficient capacity to carry ahigher 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. While there are many advantages, but because Bluetooth transmission protocol and other 2.4G devices, are common signal of this band, which will inevitably lead to the emergence signals interfere with each other. In addition, the Bluetooth protocol is not A free technology, any vendor should  use this technology to the organization pay a patent fee, which is part of the costs will be reflected in the cost, the 2012 Bluetooth audio equipment prices are still  higher than ordinary products.

   3: optional Bluetooth Speaker 
   1 compatibility. Although Bluetooth speaker basic 100% compatibility to support existing Bluetooth devices, but still find out whether your playback device supports 
Bluetooth before buying. 
   2, the chip brand. 2012 Bluetooth audio chip suppliers There are two major companies, one British company CSR, and the other is the United States of OVC companies. CSR 
Bluetooth speaker occupy most of the market entirely. 
   3, the transmission distance. Bluetooth Speaker transmission distance problem is we are more concerned about. Bluetooth Speaker Bluetooth version has nothing to do with  the transmission distance, depending on the sophistication of the technology. PowerClass2 standard biography  Transmission distance of 10 meters; while upgrading PowerClass1 transmission distance will be raised to 100 meters, and provides Hi-Fi stereo effect. In general, the phone with a Bluetooth speaker distance is not too far away, the transmission distance safer Approximately 10 meters. Bluetooth speaker market reached 10 meters standard.    4, version. When consumers purchase a Bluetooth speaker, often see Bluetooth 1.1,1.2,2.0,3.0,4.0 such as numbers, these numbers represent the different versions, but also represents the interference of Bluetooth speakers Capacity. 2012 to 2.0 most common, 3.0 is the new mainstream, 4.0 just launched shortly. Bluetooth versions, concerns the quality of the received signal. The new version also stressed overcome noise. The new version can be backward compatible, Consumers should purchase to measure price and demand. 
   5, built-in battery. Bluetooth digital speakers are built-in battery, so that the truly wireless. Built-in battery is good or bad will determine the Bluetooth digital speakers playing  
time and life. Please ask for actual play carefully before buying Time and repeated the charge decay times.

   The key people in the optional Bluetooth speaker when, in addition to functional considerations, Bluetooth speaker appearance and function are also consumers must pay attention to when  buying. Everyone likes the shape of different users to try before buying quality and functionality, and then shot to buy.
