Description
【発明の詳細な説明】 本発明は、高音域のスピーカと中低音域のスピーカと
ホーン状音道を有するスピーカ装置であり、これにより
超小型で大型並みの音質と低温と且つ少い入力に対する
高効率でローコストなスピーカを得る事ができる。DETAILED DESCRIPTION OF THE INVENTION The present invention is a speaker device having a high-range speaker, a middle- and low-range speaker, and a horn-shaped sound path. It is possible to obtain a speaker with high efficiency and low cost.
第１図および第２図は本発明実施例を示しスピーカボ
ックス１の前面部２に高音域のトゥイータ３と低中音域

のである。1 and 2 show an embodiment of the present invention, in which a tweeter 3 in the high frequency range and a full-range speaker 4 in the low and middle frequency range are detached and opened on the front surface 2 of the speaker box 1, and an upper plate 5 of the speaker box is provided. Vertically to the speaker 3,
A hole 6 is formed in a direction perpendicular to the opening direction of 4, and a horn-shaped sound path adapter 7 having a V shape and having an opening at the bottom is covered.
ホーン状音道７はスピーカボックス１の中に一体に設
けてもよく、あるいは第３図のごとくスピーカボックス
１の横側に設けてもよい。The horn-shaped sound path 7 may be provided integrally in the speaker box 1, or may be provided on the side of the speaker box 1 as shown in FIG.
トゥイータ３の第４図の如くコーン振動板８をフェノ
ール含浸紙製等のリング９にエッヂを接着させ、フレー
ム10に前記リングを接着したものである。As shown in FIG. 4 of the tweeter 3, a cone diaphragm 8 is made to adhere an edge to a ring 9 made of phenol-impregnated paper or the like, and the frame is made to adhere the ring.
このように単一スピーカボックス１に高音域と中音域
のスピーカとホーン状音道の３つを併設することによ
り、高音域と中低音域の指向特性とその両音域のつなが
りが改善され、高音域と中音域の忠実度が向上するとと
もに、ホーン状音道により低周波域および高周波域がそ
れぞれ拡張され周波数特性が極めて広くなり音質が驚く
位顕著に改善されることが実験により確かめられた。In this way, the single speaker box 1 is provided with three high-range and mid-range loudspeakers and a horn-like sound path, so that the directional characteristics of the high-range and mid-low range and the connection between both ranges are improved. Experiments have confirmed that the fidelity of the midrange and midrange is improved, and the low-frequency range and the high-frequency range are expanded by the horn-shaped sound path, the frequency characteristics are extremely widened, and the sound quality is remarkably improved.
また口径を20〜30％増大したと同様の周波数改善効果
があり、スピーカボックスが小型であるのに大型スピー
カ、大型ボックスと同じ高性能を得ることができる。In addition, there is a similar frequency improvement effect when the aperture is increased by 20 to 30%, and it is possible to obtain the same high performance as a large speaker and a large box even though the speaker box is small.
さらに、第１図および第５図に示すように低中音域ス
ピーカ４の前面中央のみに巾広の桟８、その左右に細い
桟９を有する前面カバー10を設ける事により高音域は押
えられ全体としてまろやかな音となり且つ音が左右に分
散して可聴域が広くなる。Further, as shown in FIGS. 1 and 5, by providing a wide crosspiece 8 and a front cover 10 having narrow crosspieces 9 on the left and right sides only in the center of the front surface of the low and mid range speaker 4, the high range is suppressed. As a result, the sound becomes mellow, and the sound is spread to the left and right to widen the audible range.
又、高音域スピーカ３は高温が減衰しやすい遮音材が
なくストレートに出るので高温の出力の出力低下が防止
され高域まで伸びのある音が得られ、全体として超小型
のカーステレオサイズスピーカで35ヘルツ〜20,000ヘル
ツという驚くべき高性能スピーカシステムを得る事が出
来る。Moreover, since the high-frequency speaker 3 does not have a sound insulating material that easily attenuates high temperatures and goes straight, high-frequency output is prevented from being lowered, and a sound that extends to high frequencies is obtained. You can get an amazing high performance speaker system from 35 Hertz to 20,000 Hertz.
上記実施例の他の種々の変形はすべて本発明に含まれ
るものである。All other various modifications of the above embodiment are included in the present invention.
本発明はスピーカ装置の周波数域を拡張するとともに
その特性が向上し、出力が増加する等多くの著効を有す
る画期的な発明である。The present invention is an epoch-making invention which has many remarkable effects such as extending the frequency range of a speaker device, improving its characteristics, and increasing its output.
