Application of bluetooth speaker
With the rapid development of Bluetooth smartphones and tablet computers in 2012, consumers have been amazed by their performance and screens. Due to the size, speakers alone have no good solutions. Hearing is also one of the most important human perceptions, and consumers are increasingly demanding this part. The bluetooth speaker takes advantage of the trend, and the portable way, wireless transmission, and stylish appearance are strongly loved by consumers.
Unlike other wireless speakers, Bluetooth speakers have their unique characteristics: [1]
1. Widely used
Bluetooth technical specifications are unified globally. Mobile phones, PDAs, wireless headsets, notebook computers, automobiles, medical equipment, computer peripherals and many other devices, as long as you have a Bluetooth adapter, you can easily connect to Bluetooth devices for data transmission or voice communication, which is widely popular , 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 only 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 ensure 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 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 signal interference. In addition, the Bluetooth protocol is not a free technology. Any manufacturer using 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.
