Bluetooth earphones are an advanced wireless earphone technology that can communicate with other devices, such as mobile phones, computers, tablets, etc. through the Bluetooth protocol. The working principle of Bluetooth earphones is as follows:
1. Bluetooth module: Bluetooth earphones have a built-in Bluetooth module for connecting and communicating with other devices.
2. Transmitter: Converts audio signals into radio waves and sends them to the receiver.
3. Receiver: Receives radio waves and converts them into raw audio signals.
4. Speaker: Converts the original audio signal into audible sound and transmits it to the headphone driver unit.
5. Driver unit: uses built-in transistors to control the vibration of the speaker and transmit sound to the ear.
Overall, the working principle of Bluetooth earphones is to wirelessly connect with other devices through Bluetooth technology, convert audio signals into wireless waves for transmission, and play sound through receivers, speakers, and driver units, allowing users to enjoy high-quality music or calls anytime and anywhere without wires.
