| description | The present invention relates to a pure wireless headphone with a ground reflector, pertaining to the field of communication technology, including an in-ear headphone shell and an RF signal generating device arranged in the in-ear headphone shell. The RF signal generating device includes an antenna, a main RF PCB, a battery and a charging PCB, wherein the helical antenna is used, the top tail end of which is connected with a laterally extending metal tail line. The RF signal generating device further includes a metal frame and a metal ground ring. The main RF PCB is arranged at the top of the metal frame, the metal ground ring is located under the helical antenna, and a gap is reserved between a bottom coil of the helical antenna and the top of the metal ground ring. The metal ground ring can change a radiation ground current, and adjust the angle of the radiation direction. The radiation direction of the antenna inclines about 15 degrees. A change in radiation direction ensures more stable transmission and reception of the wireless signal between the earbuds and between the main device and the audio frequency source, such that the wireless connection is more stable and reliable. |
