The antenna of Bluetooth earphones is usually a patch antenna or spiral antenna. These antennas are designed to receive and send wireless signals from Bluetooth devices and headphones.
A patch antenna is a rectangular shaped conductor in a plane, usually made of metal foil. It is designed to transmit Bluetooth signals between the left and right headphones, or up or down from the headphones.
A spiral antenna is a coil wound in a spiral shape, usually with a smaller physical size and higher efficiency. This antenna can improve the wireless reception and signal transmission capabilities of Bluetooth earphones, while reducing the possibility of signal differences and distortion.
In summary, the antenna of Bluetooth earphones is a key component, which ensures stable transmission between the earphones and devices, providing a high-quality sound quality and smooth music experience.
