Unlike other wireless speakers, Bluetooth speakers have their own unique features:
1, the application of a wide range of global Bluetooth technology specifications, mobile phones, PDAs, wireless headsets, laptops, automobiles, medical equipment, computer peripherals and many other devices, as long as you have a Bluetooth adapter, you can easily connect Bluetooth devices for data transmission or voice Communication is widely used and has good compatibility.
2, easy to operate Bluetooth technology is an instant technology, it does not require a fixed infrastructure, and easy to install and set up, do not need the cable to achieve the connection, the use of very convenient, simply complete the matching can be put into use, operation threshold Lower.
3, faster transmission speed compared to infrared and other methods, Bluetooth transmission protocol has a clear advantage in speed, Bluetooth 4.0 theoretical maximum speed of 24Mbps, faster speed can guarantee a higher sound quality, make it enough Ability to carry higher music rates.
4, the transmission distance is moderate Bluetooth transmission distance is generally within 10 meters, just the size of a room, and the partition data transmission, is ideal for home use.
Although there are many advantages, because the Bluetooth transmission protocol and other 2.4G devices share the signal of this band, it will inevitably lead to signal interference with each other. In addition, the Bluetooth protocol is not a free technology. Any manufacturer that uses this technology must pay a patent fee to the organization. This part of the cost will also be reflected in the cost. The price of Bluetooth audio equipment is still higher than today's. normal product.
