Earphone system self-adaptive to hearing characteristics of user

Abstract

The invention discloses an earphone system self-adaptive to hearing characteristics of a user, which comprises an intelligent audio playing device, a specially-made earphone and human ears, wherein amain control module and a signal output end are arranged in the intelligent audio playing device; the specially-made earphone is provided with a loudspeaker device, a sound collecting device, a signalpreprocessing circuit and a signal transmission module; the loudspeaker device is connected with the signal transmission module; the sound collecting device is connected with the signal transmissionmodule through the signal preprocessing circuit; when the specially-made earphone is worn in a sealing mode and connected with the intelligent audio playing device, the main control module transmits agenerated testing audio signal to the loudspeaker device; the main control module receives and records an otoacoustic emission signal, which is collected by the sound collecting device, is processedby the signal preprocessing circuit and exists in the external auditory canal; and the main control module analyzes the otoacoustic emission signal and adjusts the output characteristic of a music audio signal output by the signal output end through a hardware or software algorithm, so that listening feeling is improved aiming at a hearing curve of the user.

Description

technical field [0001] The invention relates to the fields of electronic communication, audio frequency and medicine, in particular to an earphone system adaptive to user's hearing characteristics. Background technique [0002] Otoacoustic Emissions (OAE) refers to a kind of weak audio energy produced in the cochlea of ​​the inner ear, which is transmitted to the external auditory canal through the ossicular chain and tympanic membrane, and is part of the normal function of the human ear. This phenomenon was first discovered by British scholar David Kemp in 1978 and used clinically. By collecting the audio energy, the sensitivity difference of a person's hearing to each frequency can be analyzed and fed back. [0003] At present, as consumers have higher requirements for hearing. Due to the existence of OAE, due to the difference or damage of the internal structure of the human ear, the difference in the auditory spectrum causes the user's perception and sensitivity to the...

Problems solved by technology

Due to the existence of OAE, each person has differences in the perception and sensitivity of the same sound due to differences in the internal structure of the human ear or damage to the auditory spectrum.
