Abstract

The invention discloses an earphone system and a control method of an earplug effect. The earphone system includes at least one speaker, at least one feed-forward microphone, at least one feedback microphone, wherein the feedback microphone is arranged at the sound output end of the loudspeaker, and when the earphone is worn, the feedback microphone is located in an ear canal and used for collecting sound signals in the ear canal; the feed-forward microphone is located on the outer side of the earphone and used for collecting environment sound signals. At least one feed-forward microphone is arranged outside the earphone, when wind exists outside, the size of wind energy can be recognized, a control circuit automatically adopts a signal of the feed-forward microphone with small wind energy as a signal for feed-forward active noise reduction and ear blockage effect elimination, and meanwhile, a signal picked up by the microphone with large wind energy is reduced or closed. The control circuit starts the vibration sensor and the feedback microphone to eliminate the ear blocking effect filter so as to eliminate the ear blocking effect.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to an earphone system and a method for controlling the earplug effect. Background technique [0002] When the opening of the external auditory canal is blocked, the bone conduction hearing threshold is lowered, which is called the occlusion effect. The reason for the ear plugging effect is that when the external auditory canal is blocked, the vibrating sound generated by the external auditory canal cannot be eliminated through the external auditory canal, resulting in about 15-30dB amplification of the self-sound signals such as talking and chewing in the eardrum, and the sound signal The frequency is mainly concentrated in 100Hz-600Hz. In some special cases, the frequency of the sound signal will also be concentrated in 50Hz-1KHz. The frequency of the sound is related to the shape and size of the cartilage of the external auditory canal, the contact area between the blocking ob...
