Description
θ=sin-1(b/a)
次に、図16(C)に示すように、内縁84の先端の周辺に着目して、フィルムスピーカ30の正面に対して平行な面Pを規定した場合、第2放音孔74のフィルムスピーカ側30の面は面Pとも交わることになる。このとき、面Pと第2放音孔74のフィルムスピーカ側30の面とで規定される角度θ’は角度θと錯角の関係となり、角度θと角度θ’とは同じ値となる。
90°>θ>sin-1(b/a)
また、図16(D)に示す角度θは、シミュレーションによって求められてもよい。ただし、シミュレーションによって角度θを求めるには複雑な計算が必要となるが、上述したように第1長さaおよび第2長さbを利用すれば、内縁84の先端を斜めに形成するときの角度θ(条件)を容易に求めることができる。
12 … バックパネル
14 … 取り付け枠
24 … 第1放音孔
30a,30b … 第1フィルムスピーカ、第2フィルムスピーカ
46a,46b … 第1スピーカホルダ、第2スピーカホルダ
74 … 第2放音孔
84 … 内縁
86 … 樹脂テープ
