Description
この発明は、多チャンネルのスピーカー装置に関するものである。 The present invention relates to a multi-channel speaker device.
従来、いろいろな楽器の音色や人の声を発すると、その音が混ざり合ってスピーカーから汚く聞こえていた。 In the past, when the tones of various musical instruments and human voices were uttered, the sounds were mixed and heard dirty from the speakers.
これは、次のような欠点があった。
従来、いろいろな楽器の音色や人の声を発すると、その音が混ざり合ってスピーカーから汚く聞こえる。厳密に言えば、高音のスピーカーでも、僅かではあるが、中音・低音の音が漏れているし、中音のスピーカーでも、僅かではあるが、高音・低音の音が漏れているし、低音のスピーカーでも、僅かではあるが、高音・中音の音が漏れていた。
つまり、一つの系統の信号(チャンネル)を、複数のスピーカーで共用していた。
本発明は、以上のような欠点をなくすためになされたものである。This had the following drawbacks.
Conventionally, when the tones of various musical instruments and human voices are uttered, the sounds are mixed and sound dirty from the speaker. Strictly speaking, even a high-pitched speaker leaks a small amount of mid-range and low-pitched sound, and a medium-pitched speaker also leaks a small amount of high-pitched and low-pitched sound, and a low-pitched sound. Even with the speaker of, there was a slight amount of high-pitched and medium-pitched sound leaking.
That is, the signal (channel) of one system was shared by a plurality of speakers.
The present invention has been made to eliminate the above-mentioned drawbacks.
まず、コンピューター(10)で、デジタル化された音のデータ、例えばCDロムなどを読み込む。そうして、何の楽器で演奏しているかとか、人の声などを、コンピューター(10)で回析(かいせき)し、その楽器は、高音の音で信号を出すのか、中音の音で信号を出すのか、低音の音で信号を出すのか、得られた結果を検知し、自動判別する。そして、それらのデジタルデータをデジタルアンプ(1)に出力する。
次に、デジタルアンプ(1)では、もし、ビオラの音が演奏されていれば、ビオラの音は高い音なので、高音の信号(チャンネル)のみを、デジタル技術のイコライザー(2)を用いて抽出し、高音のスピーカー(4)のみを出力し鳴らす。ここがポイントで、高音の音を低減・減衰するのでは無く、完全に遮断・シャットアウトするのである。つまり高音以外の音を完全にカットするのである。
同様に、バイオリンの音が演奏されていれば、バイオリンの音は中ぐらいの音なので、中音の信号(チャンネル)のみを、デジタル技術のイコライザー(2)を用いて抽出し、中音のスピーカー(5)のみを出力し鳴らす。
同様に、コントラバスの音が演奏されていれば、コントラバスの音は低い音なので、低音の信号(チャンネル)のみを、デジタル技術のイコライザー(2)を用いて抽出し、低音のスピーカー(6)のみを出力し鳴らす。
本発明は、以上の構成よりなる、多チャンネルのスピーカー装置である。First, the computer (10) reads digitized sound data such as a CD ROM. Then, what kind of instrument you are playing, human voice, etc. are diffracted by a computer (10), and that instrument outputs a signal with a high-pitched sound, a middle-pitched sound. Detects the obtained result and automatically determines whether to output a signal with a low-pitched sound or a low-pitched sound. Then, those digital data are output to the digital amplifier (1).
Next, in the digital amplifier (1), if the viola sound is played, the viola sound is high, so only the high-pitched signal (channel) is extracted using the equalizer (2) of digital technology. Then, only the high-pitched speaker (4) is output and sounded. This is the point, not to reduce or attenuate the high-pitched sound, but to completely block or shut it out. In other words, it completely cuts sounds other than high-pitched sounds.
Similarly, if the violin sound is played, the violin sound is medium sound, so only the medium sound signal (channel) is extracted using the digital technology equalizer (2), and the medium sound speaker. Only (5) is output and sounded.
Similarly, if the sound of the contrabass is played, the sound of the contrabass is low, so only the low-pitched signal (channel) is extracted using the equalizer (2) of digital technology, and the low-pitched speaker (6). ) Is output and sounds.
The present invention is a multi-channel speaker device having the above configuration.
高音のスピーカーと中音のスピーカーと低音のスピーカーが、音が混ざり合って汚く聞こえない為、クリアでノイズが少なく、まるで生演奏のオーケストラのコンサートで聴いている様な効果がある。 The high-pitched, mid-pitched, and low-pitched speakers are mixed and do not sound dirty, so they are clear and have little noise, and have the effect of listening to a live orchestra concert.
以下、本発明を実施するための形態について説明する。
まず、コンピューター(10)で、デジタル化された音のデータ、例えばCDロムなどを読み込む。そうして、何の楽器で演奏しているかとか、人の声などを、コンピューター(10)で回析(かいせき)し、その楽器は、高音の音で信号を出すのか、中音の音で信号を出すのか、低音の音で信号を出すのか、得られた結果を検知し、自動判別する。そして、それらのデジタルデータをデジタルアンプ(1)に出力する。
次に、デジタルアンプ(1)では、もし、ビオラの音が演奏されていれば、ビオラの音は高い音なので、高音の信号(チャンネル)のみを、デジタル技術のイコライザー(2)を用いて抽出し、高音のスピーカー(4)のみを出力し鳴らす。ここがポイントで、高音の音を低減・減衰するのでは無く、完全に遮断・シャットアウトするのである。つまり高音以外の音を完全にカットするのである。
同様に、バイオリンの音が演奏されていれば、バイオリンの音は中ぐらいの音なので、中音の信号(チャンネル)のみを、デジタル技術のイコライザー(2)を用いて抽出し、中音のスピーカー(5)のみを出力し鳴らす。
同様に、コントラバスの音が演奏されていれば、コントラバスの音は低い音なので、低音の信号(チャンネル)のみを、デジタル技術のイコライザー(2)を用いて抽出し、低音のスピーカー(6)のみを出力し鳴らす。
本発明は、以上のような構造である。
例では、3個のスピーカーを挙げているが、これが複数の系統の信号(チャンネル)がある場合、複数個のスピーカーが必要になってくるし、それぞれの担当とする周波数帯域も違ってくる。Hereinafter, modes for carrying out the present invention will be described.
First, the computer (10) reads digitized sound data such as a CD ROM. Then, what kind of instrument you are playing, human voice, etc. are diffracted by a computer (10), and that instrument outputs a signal with a high-pitched sound, a middle-pitched sound. Detects the obtained result and automatically determines whether to output a signal with a low-pitched sound or a low-pitched sound. Then, those digital data are output to the digital amplifier (1).
Next, in the digital amplifier (1), if the viola sound is played, the viola sound is high, so only the high-pitched signal (channel) is extracted using the equalizer (2) of digital technology. Then, only the high-pitched speaker (4) is output and sounded. This is the point, not to reduce or attenuate the high-pitched sound, but to completely block or shut it out. In other words, it completely cuts sounds other than high-pitched sounds.
Similarly, if the violin sound is played, the violin sound is medium sound, so only the medium sound signal (channel) is extracted using the digital technology equalizer (2), and the medium sound speaker. Only (5) is output and sounded.
Similarly, if the sound of the contrabass is played, the sound of the contrabass is low, so only the low-pitched signal (channel) is extracted using the equalizer (2) of digital technology, and the low-pitched speaker (6). ) Is output and sounds.
The present invention has the above structure.
In the example, three speakers are listed, but when there are signals (channels) of a plurality of systems, a plurality of speakers are required, and the frequency band in charge of each is different.
