従来のスピーカ用スタンドＡは、複数の構成部材が一体に固定されて１つの構造物になっており、機械的共振のＱ値が高くなる場合がある。したがって、スピーカの振動がスピーカ用スタンドＡに伝わると、共振周波数に近い振動成分が増幅されたり、スピーカ用スタンドＡの振動と音とが共鳴したりして、音質が低下してしまうおそれがある。 In the conventional speaker stand A, a plurality of constituent members are integrally fixed to form a single structure, and the Q value of mechanical resonance may increase. Therefore, when the vibration of the speaker is transmitted to the speaker stand A, a vibration component close to the resonance frequency may be amplified, or the vibration and sound of the speaker stand A may resonate, resulting in a decrease in sound quality. .

また、スピーカ用スタンドＢは、スピーカ用スタンドＡよりも音質が改善されるが、設置可能なスピーカの形状や大きさが限定されるという問題がある。 Further, the speaker stand B has improved sound quality as compared with the speaker stand A, but there is a problem that the shape and size of the speaker that can be installed are limited.

以下、本考案のスピーカ台の一実施形態について、図面に基づいて説明する。この実施形態のスピーカ台１０は、図１、図２に示すように、上面にスピーカが設置される天板１２と、天板１２を下方から支持する支持構造体１４とを備え、支持構造体１４は、第一及び第二の支持板１６，１８で構成されている。 Hereinafter, an embodiment of a speaker stand of the present invention will be described based on the drawings. As shown in FIGS. 1 and 2, the speaker base 10 according to this embodiment includes a top plate 12 on which a speaker is installed, and a support structure 14 that supports the top plate 12 from below. Reference numeral 14 denotes first and second support plates 16 and 18.

天板１２は、アルミニウム又はアルミニウム合金製の板であり、外形は略正方形で、中央部に透孔１２ａが開口している。 The top plate 12 is a plate made of aluminum or an aluminum alloy, has an outer shape that is substantially square, and has a through hole 12a at the center.

第一の支持板１６は、アルミニウム又はアルミニウム合金製の板である。図３（ａ）に示すように、外形は略四角形の上辺側の端部を等脚台形状に深く切り欠いたような形状で、左右の上端角部に、天板１２の周縁部を支持するための第一天板受け部１６ａが一対に設けられ、左右の下端角部に、床置きするための第一脚部１６ｂが一対に設けられている。また、２つの第一天板受け部１６ａに挟まれた中央部に、この中央部を下端から上向きに切り込んだ第一スリット１６ｃが設けられている。左右一対に設けられた略三角形の透孔１６ｄは、デザイン性を考慮して形成されたものである。 The first support plate 16 is a plate made of aluminum or aluminum alloy. As shown in FIG. 3 (a), the outer shape is a shape in which the end on the upper side of a substantially quadrilateral is deeply cut into an isosceles trapezoid, and the peripheral edge of the top 12 is supported at the upper and lower corners of the left and right. A pair of first top plate receiving portions 16a are provided, and a pair of first leg portions 16b are provided at the left and right lower corners to place the floor. Moreover, the 1st slit 16c which cut this center part upward from the lower end is provided in the center part pinched | interposed into the two 1st top-plate receiving parts 16a. The substantially triangular through holes 16d provided in the left and right pairs are formed in consideration of design.

第二の支持板１８は、第一の支持板１６とほぼ同じものであり、図４（ａ）に示すように、第一の支持板１６の第一天板受け部１６ａ、第一脚部１６ｂ、第一スリット１６ｃ及び透孔１６ｄと同様の第二天板受け部１８ａ、第二脚部１８ｂ、第二スリット１８ｃ及び透孔１８ｄを備えている。ただし、第二の支持板１８の場合、第二スリット１８ｃは、中央部を上端から下向きに切り込んで設けられているという違いがある。 The second support plate 18 is substantially the same as the first support plate 16, and as shown in FIG. 4A, the first top plate receiving portion 16 a and the first leg portion of the first support plate 16. 16b, a second top plate receiving portion 18a, a second leg portion 18b, a second slit 18c, and a through hole 18d similar to the first slit 16c and the through hole 16d are provided. However, in the case of the second support plate 18, there is a difference that the second slit 18c is provided by cutting the center portion downward from the upper end.

さらに、天板１２は、対角に位置する２つの角部の側端面に第一ガイド溝１２ｂ(1)が一対に設けられ、他の対角に位置する２つの角部の側端面に第二ガイド溝１２ｂ(2)が一対に設けられている。第一ガイド溝１２ｂ(1)は、第一の支持板１６の第一天板受け部１６ａに係合してガイドする部分で、第二ガイド溝１２ｂ(2)は、第二の支持板１８の第二天板受け部１８ａに係合してガイドする部分である。 Furthermore, the top plate 12 is provided with a pair of first guide grooves 12b (1) on the side end surfaces of the two corners positioned diagonally, and the first guide groove 12b (1) is formed on the side end surfaces of the two corners positioned on the other diagonal. Two guide grooves 12b (2) are provided as a pair. The first guide groove 12 b (1) is a portion that engages and guides the first top plate receiving portion 16 a of the first support plate 16, and the second guide groove 12 b (2) is the second support plate 18. The second top plate receiving portion 18a engages and guides the second top plate receiving portion 18a.

各部材を組み立てるときは、まず、第一及び第二の支持板１６，１８を用意し、第一及び第二天板受け部１６ａ，１６ｂを上側にして、図２に示す要領で第一及び第二スリット１６ｃ，１８ｃを着脱可能に係合させ、第一及び第二の支持板１６，１８が互いに交差した支持構造体１４を形成する。そして、支持構造体１４を、第一及び第二脚部１６ｂ，１８ｂを床置きすることによって自立させる。 When assembling each member, first, the first and second support plates 16 and 18 are prepared, the first and second top plate receiving portions 16a and 16b are set on the upper side, and the first and second steps are performed as shown in FIG. The second slits 16c and 18c are detachably engaged to form a support structure 14 in which the first and second support plates 16 and 18 intersect each other. Then, the support structure 14 is self-supported by placing the first and second leg portions 16b and 18b on the floor.

そして天板１２を用意して支持構造体１４の上方に配置し、図３（ｂ）、（ｃ）に示すように、一対の第一ガイド溝１２ｂ(1)の内側に第一天板受け部１６ａを係合させるとともに、図４（ｂ）、（ｃ）に示すように、一対の第二ガイド溝１２ｂ(2)の内側に第二天板受け部１６ａを係合させる。これで、天板１２の周縁部が第一及び第二天板受け部１６ａ，１８ａによって着脱可能に支持され、図１に示す組み立て状態となる。 Then, the top plate 12 is prepared and arranged above the support structure 14, and as shown in FIGS. 3 (b) and 3 (c), the first top plate support is placed inside the pair of first guide grooves 12b (1). While engaging the part 16a, as shown to FIG.4 (b), (c), the 2nd top-plate receiving part 16a is engaged inside a pair of 2nd guide groove 12b (2). Thus, the peripheral edge of the top plate 12 is detachably supported by the first and second top plate receiving portions 16a and 18a, and the assembled state shown in FIG. 1 is obtained.

スピーカ台１０は、複数の構成部材が一体に固定されておらず、天板１２、第一の支持板１６及び第二の支持板１８が独立して変位できる構造なので、機械的共振の周波数が分散し、機械的共振のＱ値を低くすることができる。したがって、天板１２にスピーカを設置して使用されたとき、機械的共振による音質の低下が格段に小さく抑えられる。 Since the speaker base 10 has a structure in which a plurality of constituent members are not fixed integrally and the top plate 12, the first support plate 16 and the second support plate 18 can be independently displaced, the frequency of mechanical resonance is low. It is possible to disperse and to lower the Q value of mechanical resonance. Therefore, when a speaker is installed on the top board 12, the deterioration of sound quality due to mechanical resonance can be remarkably suppressed.

なお、本考案は、上記実施形態に限定されるものではない。例えば、上記の天板１２は略正方形であるが、天板の形状は、一対の第一天板受け部と一対の第二天板受け部とで支持できる形状であればよく、例えば、円形、楕円形、多角形等、正方形以外の形状に変更してもよい。また、上記の第一及び第二ガイド溝１２ｂ(1)，１２ｂ(2)は天板１２の側端面に設けてあるが、例えば、天板の下面の一部を掘り込んで設けてもよい。 In addition, this invention is not limited to the said embodiment. For example, the top plate 12 is substantially square, but the shape of the top plate may be any shape that can be supported by the pair of first top plate receiving portions and the pair of second top plate receiving portions. The shape may be changed to a shape other than a square, such as an ellipse or a polygon. The first and second guide grooves 12b (1) and 12b (2) are provided on the side end surface of the top plate 12. However, for example, a part of the lower surface of the top plate may be dug. .

支持構造体を構成する第一及び第二の支持板は、上記の第一及び第二の支持板１６，１８の形態に限定されない。第一及び第二の支持板１６，１８は、略四角形の上辺側の端部を等脚台形状に深く切り欠いたような形状になっているが、上記の要領で組み立て可能であれば、他の形状に変更することができる。また、第一及び第二の支持板は、デザイン性等を考慮して、互いに異なる外形にしてもよい
各部材の素材は、軽くて加工性がよいアルミニウム又はアルミニウム合金が適しているが、他の素材を使用してもよい。 The first and second support plates constituting the support structure are not limited to the form of the first and second support plates 16 and 18 described above. The first and second support plates 16 and 18 are shaped like a substantially quadrangular upper end side cut out into an isosceles trapezoid, but if they can be assembled in the above manner, It can be changed to other shapes.
