3. Fast transmission speed. Compared with other methods such as infrared, the Bluetooth transmission protocol has a significant advantage in speed. The theoretical maximum speed of Bluetooth 4.0 reaches 24Mbps. A faster speed can ensure higher sound quality, so that it can carry a higher bit rate if it is satisfied. Music.
4. The transmission interval is moderate. The transmission interval 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.

Therefore, when choosing a Bluetooth speaker, you can choose a stable signal and strong anti-interference.
4. Battery. The quality of the built-in battery of the Bluetooth speaker directly determines its broadcast time and service life. Before purchasing, please inquire carefully about the actual broadcast time and the number of repeated charging attenuations. Consumers are advised to choose lithium polymer batteries as much as possible when choosing Bluetooth speakers, so there is no risk of explosion.
