Abstract

The invention discloses a radio frequency transmitting device and an earphone. A first amplifying circuit in the radio frequency transmitting device amplifies an initial radio frequency signal to generate a target radio frequency signal; and a first gating circuit feeds back the signal transmission intensity of each wireless transmitting component in the respective signal transmission direction, and correspondingly gates the wireless transmitting component with the maximum signal transmission intensity in the signal transmission direction according to the switching signal, and the component wirelessly transmits the target radio frequency signal. The first control circuit outputs an initial radio frequency signal to the first amplification circuit, and correspondingly outputs a switching signal according to the signal transmission intensity fed back by the first gating circuit. According to the radio frequency transmitting device and the earphone, the signal transmission directions of the wireless transmitting assemblies are different, the target radio frequency signal is only sent outwards in the direction with the maximum signal transmission intensity, and the target radio frequency signal is obtained after the initial radio frequency signal is amplified, so that the effective communication distance is increased, the signal fidelity is high, and the user experience is high.

Description

technical field [0001] The application belongs to the technical field of audio equipment, and in particular relates to a radio frequency transmitting device and an earphone. Background technique [0002] Wireless radio frequency headsets are widely used in games, music, calls, video playback and other scenarios. Compared with Bluetooth headsets, wireless radio frequency headsets have stronger transmission stability. The radio frequency earphone is composed of a radio frequency transmitting device and a radio frequency receiving device. However, compared with Bluetooth headsets, the transmission power of the radio frequency transmitting device of traditional wireless radio headsets is only 2dB, and the effective communication distance is relatively short. Long-distance (10m-20m) communication is likely to cause signal distortion and poor user experience. [0003] Therefore, the traditional radio frequency transmitting device has a short effective communication distance, whic...
