Automatic Tunable Earphone And Method For Tuning The Same

Abstract

An automatic tunable earphone connected with an external audio device has an audio signal output unit, a loudspeaker, a microphone, a data memorizer and an arithmetic unit. The audio signal output unit outputs a testing audio signal into the loudspeaker for generating a testing sound which is transmitted into an ear canal. The microphone placed in the ear canal receives the sound that has past through the ear canal and outputs a contrastive audio signal into the data memorizer for restoring. The arithmetic unit compares the contrastive audio signal with the testing audio signal to find out the frequency that needs to be strengthened. The frequency is restored into the data memorizer. When the external audio device outputs a raw signal, the arithmetic unit process the raw signal according to the frequency restored and outputs the processed signal into the loudspeaker for making sound.
