Description
本発明の音場創生装置には、頭内定位や不自然な定位感を解消することが可能であるという利点がある。また、受音環境の影響を排除して任意の音場を創造することも可能であるという利点もある。 The sound field creation device of the present invention has an advantage that it is possible to eliminate the in-head localization and unnatural localization. There is also an advantage that an arbitrary sound field can be created by eliminating the influence of the sound receiving environment.
音源１０は、本発明の音場創生装置が創生する音場のソースとなる音を供給するものである。供給する音は如何なる音であっても構わない。具体的には、例えば音楽ＣＤやＤＶＤ等に記録された音情報を再生する装置であれば良い。また、再生する音は、ステレオ音であってもモノラル音であっても良いし、５．１ｃｈ等の多チャンネル信号であっても良い。さらに、反射音が含まれている音や、反射音が含まれない直接音であっても良い。 The sound source 10 supplies sound that is the source of the sound field created by the sound field creation device of the present invention. The sound to be supplied may be any sound. Specifically, any device that reproduces sound information recorded on, for example, a music CD or DVD may be used. The sound to be reproduced may be a stereo sound or a monaural sound, or may be a multi-channel signal such as 5.1ch. Furthermore, it may be a sound that includes a reflected sound or a direct sound that does not include a reflected sound.
スピーカ２０は、音源１０からの音を出力するものである。スピーカ２０は、少なくとも１つ以上あれば良い。即ち、モノラル再生であればスピーカは１つで足り、ステレオ再生であれば、スピーカは最低２つあれば良い。さらに、５．１ｃｈ等の多チャンネルの場合には、例えば前方のチャンネルを再生する３つのスピーカであっても良い。また、スピーカ２０の配置場所は特に限定されない。本発明の音場創生装置では、スピーカを聴取者の前方に配置すれば、聴取者は音が前方から発生していると認識する。したがって、例えば、映像付きのオーケストラのＤＶＤを視聴する場合において、前方のモニタの近傍に配置すれば、聴取者はモニタに映し出されるオーケストラの方向から音が発生しているように感じる。なお、本発明の音場創生装置のスピーカは、特定のものには限定されず、一般的に入手可能なものであれば良い。 The speaker 20 outputs sound from the sound source 10. There may be at least one speaker 20. That is, only one speaker is sufficient for monaural reproduction, and at least two speakers are sufficient for stereo reproduction. Further, in the case of multi-channel such as 5.1ch, for example, three speakers for reproducing the front channel may be used. Moreover, the arrangement | positioning location of the speaker 20 is not specifically limited. In the sound field creation device of the present invention, if the speaker is arranged in front of the listener, the listener recognizes that the sound is generated from the front. Therefore, for example, when viewing an orchestra DVD with video, if it is placed near the front monitor, the listener feels that sound is being generated from the direction of the orchestra displayed on the monitor. In addition, the speaker of the sound field creation apparatus of this invention is not limited to a specific thing, What is necessary is just generally available.
開放型ヘッドホン４０は、上述した反射音生成部３０からの反射音を出力するものである。即ち、開放型ヘッドホン４０からは、反射音のみが出力される。後述のように、反射音生成部３０により生成された反射音は、信号処理部５０を介して開放型ヘッドホン４０により出力される。開放型ヘッドホン４０は、例えばオープンエアー型ヘッドホンとも呼ばれるものであり、発音部の背面が開放されており、外部の音が自由に出入り可能なものである。また、ヘッドホンの背面部だけではなく、耳面部側にも空間を設けたものであっても良い。なお、本発明の音場創生装置の開放型ヘッドホンは、特定のものには限定されず、一般的に入手可能なものであれば良い。 The open headphone 40 outputs the reflected sound from the reflected sound generating unit 30 described above. That is, only the reflected sound is output from the open type headphones 40. As described later, the reflected sound generated by the reflected sound generation unit 30 is output by the open headphones 40 via the signal processing unit 50. The open headphone 40 is also called, for example, an open air headphone, and the back surface of the sound generation unit is open so that external sounds can freely enter and exit. Further, a space may be provided not only on the back surface portion of the headphones but also on the ear surface portion side. The open headphones of the sound field creation device of the present invention are not limited to specific ones, and may be any generally available headphones.
さらに、本発明の音場創生装置によれば、聴取者が頭を回転したとしても、スピーカの位置は固定されているため、常にスピーカの方向に音の発声方向が定位することになる。したがって、不自然な定位感も解消することが可能となる。このように、本発明の音場創生装置によれば、聴取者の横や後方にスピーカを設置しなくても音場創生が可能である。
Furthermore, according to the sound field creation device of the present invention, even if the listener rotates his / her head, the position of the speaker is fixed, so that the direction of sound production is always localized in the direction of the speaker. Therefore, it is possible to eliminate unnatural localization. Thus, according to the sound field creation device of the present invention, it is possible to create a sound field without installing a speaker next to or behind the listener.
