なる。In conventional speaker systems having four or more speaker elements or three or more speaker elements and one passive radiator, each speaker element and passive radiator are arranged at each vertex of an arbitrary polygon.
In this case, the distances from each speaker element and passive radiator to the measuring point or listening point are generally different.

う欠点がある。Therefore, even if the outputs of each speaker element and passive radiator are well aligned, and no matter how omnidirectional each speaker element is, at the measuring point or listening point, the sound from the speaker elements and passive radiator near those points The disadvantage is that the sound is strong, but the sound from a distant object is weak.

欠点を解決するものである。The present invention solves the above-mentioned conventional drawbacks by arranging at least four speaker elements or at least three speaker elements and one passive radiator on one circumference.
以下本発明になるスピーカシステムを図に示す実施例に
より説明する。DESCRIPTION OF THE PREFERRED EMBODIMENTS The speaker system according to the present invention will be described below with reference to embodiments shown in the drawings.

ぞれのスピーカ１，２，３゜４は１つの円５の円周上に
装置されている。In the present invention, at least four speaker elements having different frequency bands or at least three speaker elements each having different frequency bands and a passive radiator are arranged on one circumference, and in the figure, 1 is a bass speaker; 2 and 3 are speakers for medium sounds, and 4 are speakers for high sounds.The center of the diaphragm of each speaker is placed on the virtual circle 5, and each speaker 1, 2, 3° 4 is arranged on the circumference of one circle 5.

いが、互の距離は小さい程円５の中心軸上以外の点での
各スピーカニレメンＮ、２゜３．４．’ｌ’）らの距離
の差が小さくなるのでよい。Here, each speaker element L2, 3.4 must be arranged at intervals so as not to interfere with each other dimensionally, but the smaller the distance between each other, the more each speaker element at a point other than the center axis of circle 5. Niremen N, 2°3.4. 'l') is good because the difference in distance between them becomes small.
円周方向の配置の順序は任意であるが、受持ち帯域の周
波数の順に配置するのが一般的である。Although the order of arrangement in the circumferential direction is arbitrary, it is common to arrange them in the order of the frequency of the assigned band.
なお図に示したスピーカニレメンＮ、２，３．４（７）
うちいずれか１個をパッシブラジエタで構成してもよい
。In addition, the speaker name N, 2, 3.4 (7) shown in the figure
Any one of them may be a passive radiator.
このような構成としたので、円５の中心軸上の任意の１

カシステムの理論ニ従って揃えれば理論通りの合成音圧
が得られる。With this configuration, any point on the central axis of the circle 5
At a point, each speaker element l arranged on the circumference,
Since the distances from 2 and 3.4 are equal, if the outputs of each speaker element and passive radiator are aligned according to the theory of a multi-way speaker system, a theoretical composite sound pressure can be obtained.
５個以上のスピーカエレメントまたは４個以上のスピー
カエレメントと１個のパッシブラジエタからなるスピー
カシステムの場合は、例えばスピーカシステムの使用目
的に対して重要順位の低いエレメントまたはパッシブラ
ジエタを円周上からはずしてもよい。In the case of a speaker system consisting of 5 or more speaker elements or 4 or more speaker elements and one passive radiator, for example, remove the elements or passive radiator that are less important for the intended use of the speaker system from the circumference. It's okay.
ウーファとパッシブラジエタ間の距離が近すぎると相互
放射インピーダンスが無視できなくなり理論が複雑とな
るので一般にこの距離を大きくすることが多い。If the distance between the woofer and the passive radiator is too short, the mutual radiation impedance cannot be ignored and the theory becomes complicated, so generally this distance is often increased.
この場合仮想の円を大きくして距離を大きくすることが
できるが、パッシブラジエタだけを仮想の円の円周上か
らはずせばよい。In this case, the virtual circle can be enlarged to increase the distance, but only the passive radiator needs to be removed from the circumference of the virtual circle.

ートと読みかえてもよい。Note that in the present invention, a passive radiator and a port can be considered to be equivalent in a bass reflex speaker system, so a passive radiator may be read as a port.

それら２つの周波数帯域の中間の周波数帯域についての
音質評価がより正確にできる。In the present invention, if a straight line connecting the center of a speaker element or passive radiator that receives one frequency band and the adjacent frequency band immediately above or below it is arranged perpendicular to the bottom surface of the speaker system, ,
During general dual listening, interference of waves of the same frequency radiated from each speaker element or passive radiator can be avoided in the horizontal direction.
Sound quality evaluation for a frequency band intermediate between these two frequency bands can be performed more accurately.
これは一般に比較的波長の短かいシステムの最高周波数
帯域を受は持つスピーカエレメントとそのすぐ下の周波
数帯域を受は持つスピーカエレメントに適用した時聴感
上最も効果的である。Generally, this is most effective in terms of audibility when applied to a speaker element that receives the highest frequency band of a system with a relatively short wavelength, and a speaker element that receives the frequency band immediately below it.
