The Bluetooth speaker is the application of Bluetooth technology to traditional digital and multimedia speakers, allowing users to avoid the annoying wires and listen to music in a variety of ways. Since the advent of Bluetooth speakers, with the development of smart terminals, it has attracted widespread attention from users such as mobile phones and tablets. Bluetooth technology (Bluetooth) makes it possible to make speakers wireless. Various well-known brands have launched many "Bluetooth speakers" with a variety of shapes. Consumers can have them for prices ranging from tens of yuan to more than 3,000 yuan Super stylish and convenient Bluetooth speaker.

 

Features:

1. Widely used

Bluetooth technology specifications are unified globally. Mobile phones, PDAs, wireless headsets, laptops, automobiles, medical equipment, computer peripherals and many other devices can easily connect to Bluetooth devices for data transmission or voice communication as long as they have a Bluetooth adapter. , Good compatibility.

2. Easy to operate

Bluetooth technology is a real-time technology. It does not require a fixed infrastructure, and is easy to install and set up. It can be connected without a cable. It is very convenient to use. It can be put into use by simply completing the pairing, and the operation threshold is low.

3. Faster transmission speed

Compared with other methods such as infrared, the Bluetooth transmission protocol has obvious advantages in speed. The theoretical maximum speed of Bluetooth 4.0 reaches 24Mbps. A faster speed can guarantee higher sound quality and make it have enough capacity to carry higher bit rates. Music.

4. Moderate transmission distance

The transmission distance of Bluetooth is generally within 10 meters, which is exactly the size of a room, and can transmit data across walls, which is very suitable for home environment use.

 

Although there are many advantages, the Bluetooth transmission protocol, like other 2.4G devices, shares signals in this frequency band, which will inevitably lead to 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, and this part of the fee will also be reflected in the cost. In 2012, the price of Bluetooth audio equipment was still high for ordinary products.
