1. Wide range of applications
Bluetooth technical specifications are unified globally. Mobile phones, PDAs, wireless headsets, laptops, automobiles, medical equipment, computer peripherals and many other devices, as long as they have Bluetooth The adapter can easily connect to Bluetooth devices for data transmission or voice communication. It is widely popular and has good compatibility.
2. Easy to operate
Bluetooth technology is an instant technology that does not require fixed infrastructure and is easy to install and set up. It does not require cables to connect and is very easy to use. Convenient, you only need to complete the pairing to put it into use, 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, which is faster. Speed ??can ensure higher sound quality, making it capable of carrying music with higher bit rates.
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, making it very suitable for use in home environments.
Although it has many advantages, because the Bluetooth transmission protocol, like other 2.4G devices, only uses signals in this frequency band, this 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, and this part of the fee will also be reflected in the cost. In 2012 The price of Bluetooth audio equipment is still higher than that of ordinary products.

How to improve the sound quality of Bluetooth speakers:
1. Adjust the volume of smart terminals such as computers, tablets, mobile phones, etc. to about 80% volume , adjust the speaker volume to 80% and below, not too high or too low.
2. The less interference, the better the sound. Indoor household appliances and computers should avoid sharing a power supply with the audio system. Even if they are placed together, they should obtain power from elsewhere. Secondly, tangling the wiring together will cause the wires to absorb noise from each other and damage the sound quality. Both equipment and cables should be kept free from interference from other electrical appliances or power cords. Try to use them separately.
3. During the playback process, try to use the speaker to play as many music types as possible, so that the high, medium and low frequencies of the speaker can be fully stretched. Prevent the shrapnel of the speaker from aging if it is not used for a long time.
4. Furniture and sundries are already good sound-absorbing materials, and laying a carpet can basically enhance the sound-absorbing effect. The advantage of adding carpet is that it can reduce the reflection sound from the floor and avoid mixing the sound coming from the front to cause turbidity. In addition, the glass and mirrors in the room will have strong sound reflection effects, and curtains need to be used to block them to solve the problem. Adopting these measures can effectively absorb sound and prevent speaker reverberation.
5. Place a dollar coin behind the speaker or place a cork pad (or rubber pad) at each of the four corners of the bottom of the speaker to increase the earthquake resistance and improve the sound quality of the speaker.
