Abstract

A method of compensating audio frequency response characteristics of a portable sound system can be performed using acoustic characteristics of a user measured in real-time. The method of compensating the audio frequency response characteristics can be used by a portable sound system. The method includes generating an acoustic characteristics curve of a user based on a minimum perception level of a user with respect to audible audio frequency bandwidths, generating an acoustic compensation curve of the user based on the acoustic characteristics curve of the user and a predetermined frequency characteristics target curve, and compensating the audio frequency response characteristics of a sound based on the acoustic compensation curve of the user.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2004-0113702 filed with the Korean Intellectual Property Office on December 28, 2004, the disclosure of which is hereby incorporated by reference. technical field [0002] The present general inventive concept relates to a portable sound system, and more particularly, to a method of compensating audio frequency response characteristics of a portable sound system using real-time measured user's acoustic characteristics, and a method using the same. sound system. Background technique [0003] Typically, conventional portable sound systems output music to the user's ears through earphones. Such conventional portable sound systems use preset equalizers (for example, with a modern rock mode and a jazz mode) to compensate for poor audio frequency response characteristics when reproducing music through headphones in the user's ears, regardless of the user'...
