Abstract

PROBLEM TO BE SOLVED: To reproduce a sound field in every direction with a headphone by extending a stereophonic sound in terms of three-dimensions.
SOLUTION: A digital surround circuit 4 varies a signal from an amplifier 1 of a headphone stereophonic main body by a time difference of 1/1800s-1/3600s, and the resulting signal is fed to a surround amplifier 3, from which the signal is outputted to a 3-D backup loudspeaker 6 which is placed slightly behind an upper middle part of the headphone to reproduce a 3-D signal. The reproduction of a delicate sound required for 3-D is attained by sounding a surround sound from a rear head with the time difference in addition to a delicate horizontal moving sense of the headphone.

【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】この考案はヘッドホンステレオに関するものである。 BACKGROUND OF THE invention relates to a headphone stereo.

【0002】 [0002]

【従来の技術】従来のヘッドホンステレオは左右のスピーカーのみで再生していて,音の左右の移動感の再生をしていた。 A conventional headphone stereo is being played only in the left and right of the speaker, he had a reproduction of the left and right of the moving sense of sound. 拡がりの音は,再生録音可能で,安易感のある音は楽しめた。 The sound of the spread is, a renewable recording, enjoyed sound with easy feeling.

【0003】 [0003]

【発明の解決する課題】従って,より3−D感を得る為,前後の音も再生するシステムが必要とされる。 A resolve OF THE INVENTION Accordingly, in order to obtain a more 3-D sense, is needed is a system to reproduce even before and after the sound.

【実施例】ヘッドホンステレオ本体のアンプ(1)のL. [Example] L. of headphone stereo body of the amplifier (1) Rch両方を結線してデジタル変換回路(2)でデジタル化した信号をデジタルサラウンド回路(4)で1 By connecting the Rch both digitized signal by a digital converter circuit (2) in digital surround circuit (4) 1
/1800s〜1/3600Sの時間差可変し,D−A / 1800s~1 / and time difference variable 3600S, D-A
変換回路(5)でアナログ信号変換,サラウンド時間はソースに合わせて調整し,TVステレオ信号やFM・A Analog signal converted by the converter circuit (5), surround time was adjusted according to the source, TV stereo signal and FM · A
Mステレオ信号,CD・MDステレオ信号,ステレオテープ信号,いずれも再生しサラウンドアンプ(3)へ加えて従来のヘッドホンの上部中央部やや後方の3−Dバックアップスピーカー(6)へ印加し3−D再生する。 M stereo signal, CD · MD stereo signal, the stereo tape signal, both applied in addition to the reproduced surround amplifier (3) to the upper central portion slightly rearward of the 3-D backup speaker conventional headphones (6) 3-D Reproduce.
ヘッドホンの微妙な左右の移動感にサラウンド音声を後頭部から時間差を付けて音を出すことにより,3−Dに必要な微妙な音の再生を可能とする。 By issuing a sound movement sense subtle left and right headphone surround sound from the back of the head with a time difference to allow the reproduction of subtle sound required 3-D. 3−Dヘッドホンステレオの原理は眼鏡式立体テレビの原理に基づくもので,テレビと視覚者の距離がサラウンド回路の時間差に基づく距離で2つの眼鏡にずれを生じた画像が入る角度がヘッドホンのL・Rchの音像の移動速度と同じであり,その交差位置に音像が現れる。 3-D principle headphone stereo is based on the principle of an eyeglass type stereoscopic television, TV and viewer distance two angles glasses entering image caused deviation in distance based on the time difference of the surround circuit of the headphone L · Rch is the same as the sound image movement speed of the sound image appears in its intersections. スピーカー方式のサラウンド再生は誤差の大きいコンピューターの3−D画像の様なものである。 Surround sound speaker system are those, such as the 3-D image of the big computer error. それを眼鏡に値するヘッドホンで微細にして3−D感覚を向上させている。 And it improves the 3-D sensation in the fine headphones worth spectacles. モノラルの場合,脳の中心に音像が定位しており,両耳を結ぶ直線上の2点間をLch,Rchの音像がステレオの場合移動する。 For mono, the center of the brain and the sound image is localized, between two points on a straight line connecting the ears Lch, the sound image of the Rch is moved for stereo. サラウンドアンプ(3)から3−DバックアップスピーカーはLch,Rchがわずかにずれており,2 3-D backup speaker from surround amplifier (3) is Lch, it is offset slightly Rch, 2
点間からの音波の発生にてこれら4点を結ぶ直線の交差が出現し3−D音像が移動する。 Intersection of the straight line is 3-D sound image moves emergence connecting these four points in waves generated from between the points. 又,2−D(ステレオ)と3−Dを切り換えるスイッチ(11)を設ける。 Further, 2-D (stereo) and a switch (11) for switching the 3-D.
左右のヘッドホンは従来通りL,Rch信号を加えて再生する。 The left and right headphones to play in addition conventional L, and Rch signals. サラウンドアンプ(3)は100mW程度とする。 Surround amplifier (3) is about 100mW.

【0007】 [0007]

【発明の効果】3−D感のある音の再生を可能とするヘッドホンステレオとして,3次元立体音響の前後左右の音場の移動感を得る。 As headphone stereos to enable reproduction of the Effect of the Invention 3-D with a sense of sound to obtain a movement feeling before and after the left and right sound field three-dimensional sound.
