AI Technical Summary

Technical Problem

Wearable open-ear speakers experience variations in transfer characteristics due to different wearing positions, affecting stereophonic sound reproduction, and existing correction systems are not applicable to these types of speakers.

Method used

A transfer characteristic correction device with a display control unit, input receiving unit, and equalizer processing unit that allows users to select parameters for equalizing transfer characteristics through a graphical equalizer, enabling interactive correction of acoustic signals.

Benefits of technology

Enables users to effectively cancel out transfer characteristics specific to wearable open-ear speakers, improving the stereophonic effect by allowing flexible parameter selection and real-time equalization.

Abstract

The present invention provides a transfer characteristics correction device including: a display control unit that executes control to display, in the form of a graphical equalizer, transfer characteristics from a speaker driver of a wearable open-ear speaker to the external auditory canal entrance; an input reception unit that determines an equalizer parameter for correction, which is a parameter for correcting the transfer characteristics, on the basis of user input with respect to the graphical equalizer; and an equalizer processing unit that executes equalizing of an acoustic signal on the basis of the equalizer parameter for correction.
