Embodiment Construction

[0025] Reference will now be made in detail to embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements. The embodiments are described below in order to describe the present general inventive concept by referring to the figures.

[0026] FIG. 1 illustrates an earphone used in a portable audio reproducing apparatus according to the present general inventive concept.

[0027] Referring to FIG. 1 , the earphone includes an earpiece 110 , a speaker unit 120 , an earphone case 130 and a microphone 140 .

[0028] The microphone 140 faces the outside of the ear, receives external noise, and outputs microphone signals (MIC+, MIC−) having inverted output characteristics with respect to the received external noise. In other words, the microphone receives an input signal (eg, external noise) and outputs an output signal (eg, anti-noise) completely out of phase with the inp...

Abstract

An apparatus and method of reducing noise in a portable audio reproducing apparatus using earphones. The apparatus includes an earphone unit having a speaker unit and a microphone to output an audio signal and to generate anti-noise with respect to external noise, and a circuit unit to compensate a frequency characteristic of the anti-noise generated by the microphone of the earphone unit, to add the anti-noise to an input audio signal, and to remove background noise using the anti-noise by outputting the audio signal having the anti-noise to the speaker unit.

Description

[0001] Related Application Cross Reference [0002] This application claims priority from Korean Patent Application No. 10-2006-0004174 filed in the Korean Intellectual Property Office on Jan. 14, 2006, the entire contents of which are hereby incorporated by reference. technical field [0003] The present general inventive concept relates to a portable audio reproducing device, and more particularly, to an apparatus and method for reducing noise in a portable audio reproducing device using an earphone. Background technique [0004] Audio reproducing devices capable of reproducing sounds such as music and voice are becoming more portable with the development of related industries. These portable audio reproduction devices enable listening to music or learning a language regardless of location, for example, in a subway, on a bus, or on the road. Examples of such portable audio reproduction devices include MP3 players, media players, minicassette players, and CD players. [0...
