Bluetooth headphones are headphones that utilize Bluetooth technology for wireless audio transmission. Its working principle is the transmission of Bluetooth signals. When using Bluetooth headphones, they are first connected through an internal Bluetooth chip. The built-in Bluetooth chip of the earphone will send a Bluetooth signal to nearby devices for connection. After successful connection, a Bluetooth signal channel will be established between the earphone and the device for audio transmission.
After being processed by the internal encoder of the device, the audio signal will be converted into a digital signal for transmission. After the transmission is completed, the built-in decoder of the earphone will convert the digital signal back into an audio signal, and then play it out through the earphone's speaker.
In addition, Bluetooth earphones can also improve sound quality through some special technologies. For example, high-definition audio transmission technology and active noise cancellation technology can improve sound quality while reducing the impact of environmental noise, allowing users to have a better auditory experience.
In short, Bluetooth headphones transmit audio through Bluetooth wireless technology, and their working principle is to connect and transmit audio through Bluetooth signals. With the continuous progress of technology, the technology of Bluetooth earphones will continue to be updated and developed, bringing a better user experience.
