【発明の詳細な説明】
本発明は、スピーカーの再生音を良好な音質で能率良く
再生するためのスピーカーボックスに関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker box for efficiently reproducing sound from a speaker with good sound quality.
一般にスピーカーで音を出す時、スピーカーの背面の音
を何らかの方法で処理しなければ、前面の音と背面の音
は逆位相のためお互に打消し合って能率が悪（なると云
うのが再生理論である。Generally, when producing sound with a speaker, unless the sound from the back of the speaker is processed in some way, the sound from the front and the sound from the back will be out of phase and will cancel each other out, resulting in poor playback efficiency. It's a theory.
処理の方法としてスピーカーを、（１）バフルに取付け
る。（２）密閉箱に取付ける。（３）位相反転箱に取付
ける。（４）バックロード型箱に取付ける。等が有るが
、これらは次の様な欠点が有る。As a processing method, the speaker is (1) attached to a baffle. (2) Install in a sealed box. (3) Attach to the phase inversion box. (4) Attach to a backload type box. etc., but these have the following drawbacks.
（１）はバブルの面積を相当大きくしなければ低音を充
分再生出来ない。In (1), bass cannot be reproduced sufficiently unless the area of the bubble is made considerably large.
（２）はスピーカーの背面を箱で密閉し、背面の音を全
部吸収する方式で有るが、スピーカーコーンの動きによ
り内部の圧力が増減しスピーカーコーンの動きを妨げる
ため能率が悪く、又混変調歪が生じ易い。(2) is a method in which the back of the speaker is sealed with a box and all the sound from the back is absorbed, but the movement of the speaker cone increases or decreases the internal pressure, which impedes the movement of the speaker cone, making it inefficient and cross-modulating. Distortion is likely to occur.
（３）はスピーカーの背面の音の一部・を小さなダクト
から前面に出し低音域の音を増強するもので有るが、箱
の内部で空気が振動を続けるため特定の音で共振を起こ
し、この共振音が他の音を妨害して低音域の音階がはっ
きりせず音の切れが悪い。In (3), a part of the sound from the back of the speaker is brought to the front through a small duct to enhance the low range sound, but as the air continues to vibrate inside the box, it causes resonance with a specific sound. This resonant sound interferes with other sounds, making the scale in the low range unclear and causing poor sound clarity.
（４）はスピーカーの背面にホーンを取り（＝Ｉけて低
音域の位相を反転させて前面に出し、スピーカーの前面
の音と重ねて能率を良くするもので有るが、構造が複雑
で特定の周波数に同調し易く周波数特性に大きな１１１
谷が生じ、ポーンの長さを余程長（しないと超低域の周
波数ではスピーカーの前面の音と背面の音が互に打消し
合って、急激に音量が低下し迫力のない音となる。(4) is a method in which a horn is placed on the back of the speaker (=I), the phase of the bass range is inverted and brought to the front, and the sound is overlapped with the sound from the front of the speaker to improve efficiency, but the structure is complex and specific 111, which is easy to tune to the frequency of
Valleys will appear, and if you don't make the length of the pawn too long, the sound from the front and back of the speaker will cancel each other out at extremely low frequencies, resulting in a sudden drop in volume and a less powerful sound. .
以」二の様に従来の方法では各々欠点が有った。Each of the conventional methods had drawbacks as described below.
これらの欠点を無くしたのが本発明で有り以下図面によ
って説明する。The present invention eliminates these drawbacks and will be explained below with reference to the drawings.

る。FIG. 1 is a front view, a lower sectional view, and a side sectional view of the present invention,
Sound from the back of the speaker ( ) is absorbed by the sound absorbing material part 1'El and the sound absorbing box (3). In this case, the sound-absorbing box (3)
vibrates due to sound pressure, but a sponge-like cushioning material (hereinafter referred to as cushioning material) (4) alleviates the transmission of vibration to the baffle (2). Since the speaker (1) and the baffle (2) vibrate in the same direction, the effect of the vibration of the sound-absorbing box (3), which vibrates differently from the baffle (2), is small, resulting in improved efficiency and efficiency compared to conventional sealed boxes. Improves sound quality. Furthermore, the increase or decrease in the internal pressure of the sound absorbing box (3) becomes air -kM%, which enters between the baffle (2) and the sound absorbing box (3) and acts on the entire baffle (2). This gap allows breathing due to the function of the buffer material (4) and also alleviates changes in internal pressure. In conventional sealed boxes, the cone of the speaker (1) receives all the changes in internal pressure, which suppresses the movement of the cone, resulting in poor efficiency and cross-modulation distortion (this is because the sound quality is poor).Also, the baffle (2) By adjusting the gap between the speaker box and the sound-absorbing box (3), the sound reflection conditions inside the speaker box change, making it possible to reduce the generation of standing waves due to specific frequencies.

のスピーカーボックスでも充分な低音を再生出来る。Figure 2 shows the cushioning material (4) with a gap so that air can freely flow in and out between the baffle (2) and the sound-absorbing box (3). Sound is absorbed by sound-absorbing materials (
5) and a sound absorbing box (3). Increases and decreases in internal pressure result in air entering and exiting (9), and the effect on the speed cutter 111 is minimal. Baffle (2) and sound absorption box (3)
The sound (8) leaking from between the speakers (1)
′! Since the direction is perpendicular to 116), there is little influence. The effect on the speaker (2) is also reduced, and even a relatively small speaker box can reproduce sufficient bass.

。Furthermore, the easy movement of the cone of Speaker +11 increases compliance, making the playback sound clearer at low volumes and increasing the dynamic range, and when listening in stereo, the localization, spread, and power of the sound are all outstanding. There was. In particular, the separation of the scales of low instruments such as contrapass is wonderful. In addition, when using it for broadcasting equipment, the sound absorption efficiency (5
) is sufficient without using it, but when using it with a high-fidelity stereo, it is better to use sound-absorbing material (5).
