この考案は、電気音響機器の分野におけるスピ
ーカキヤビネツト用の装飾板の構造の改良に関す
る。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement in the structure of a decorative plate for a speaker cabinet in the field of electroacoustic equipment.
スピーカキヤビネツトの前面装飾布は、安価な
キヤビネツトでは装飾布をバツフル板に直接張り
付けているが、通常は第５図ａに示すごとくキヤ
ビネツト本体５３とは別部材からなる装飾布取付

一般的である。
In inexpensive cabinets, the front decorative cloth of the speaker cabinet is attached directly to the butt-full board, but normally it is attached to the decorative cloth mounting plate 51, which is a separate member from the cabinet body 53, as shown in Figure 5a. It is common to have a structure in which a front decorative plate with a decorative cloth 52 pasted thereon is removably attached to the cabinet body 53.
上記した構造のキヤビネツトにおいては、装飾
布取付板５１は、従来は木製であつたが現在は合
成樹脂を一体成形したものが量産性に富み、外観
的にも良好である点から多用されている。 In the cabinet having the above structure, the decorative cloth mounting plate 51 was conventionally made of wood, but now it is often made of integrally molded synthetic resin because it is easy to mass produce and has a good appearance. .
上記構造のスピーカキヤビネツトが高温環境に
遭遇すると装飾布５２は収縮し、その張力によつ

湾曲して垂下し、外観が不良になるだけでなく、
バツフル板、或はスピーカ振動板に接触して異常
音を生じさせる欠点を有していた。
When the speaker cabinet having the above structure encounters a high-temperature environment, the decorative cloth 52 contracts, and its tension deforms the cross section as shown in FIG. In addition to becoming
It has the disadvantage that it comes into contact with the baffle plate or the speaker diaphragm, producing abnormal noise.
また、装飾布取付板５１が合成樹脂製であるた
め塑性により変形が永久に残留するので、スピー
カシステムを不良とする大きい要因となつてい
た。 Furthermore, since the decorative cloth mounting plate 51 is made of synthetic resin, deformation remains permanently due to plasticity, which is a major factor in the failure of the speaker system.
上記従来例の欠点を解決するために、本考案の
スピーカキヤビネツト用装飾板においては、装飾

In order to solve the above-mentioned drawbacks of the conventional example, in the speaker cabinet decorative plate of the present invention, the decorative cloth mounting plate to which the decorative cloth is pasted is integrally molded from synthetic resin, and the decorative cloth mounting plate to which the decorative cloth is pasted is integrally molded. frame and
It consists of one or more inner crosspieces for preventing deformation, has a structure in which a notch is provided from the back near the joint boundary between the inner crosspiece and the outer frame, and a thin wall is formed on the front surface of the outer frame. .
このような構造の外枠を有するスピーカキヤビ
ネツト用装飾板においては、装飾布が熱により収
縮し、外枠の前方が張力を受けて内方に変形して

該肉薄部が大きく屈曲するのみで中桟は少しも変
形垂下することはなく、従来例の有する欠点は除
去されることとなる。
In a decorative panel for a speaker cabinet having an outer frame having such a structure, even if the decorative fabric shrinks due to heat and the front of the outer frame receives tension and deforms inward, the inner frame cannot be removed in conventional examples. The moment due to the tension that caused the bending is not transmitted to the inside of the thin section, and therefore, as shown in Figure 4a, the thin section only bends greatly and the middle crosspiece does not deform or sag in the slightest. Therefore, the drawbacks of the conventional example are eliminated.
第１図、第２図は実施例を示し、１は装飾布
取付板で低発泡スチロール樹脂で１本成形され、
装飾布２を張り付ける外枠１ａと、該外枠１ａの
変形を防止するための中桟１ｂとから構成されて
いる。
Figures 1 and 2 show examples, 1 is a decorative cloth mounting plate molded from low-foam polystyrene resin,
It is composed of an outer frame 1a to which a decorative cloth 2 is pasted, and a middle crosspiece 1b for preventing deformation of the outer frame 1a.
外枠１ａと中桟１ｂとは、材料を節約するため
に断面がコ字型となつているが、一般的には断面
形状はこれに限定されるものではない。 Although the outer frame 1a and the middle crosspiece 1b have a U-shaped cross section in order to save material, the cross-sectional shape is generally not limited to this.
また材料も上記低発泡スチロールに限定される
ことなく、ABS樹脂、その他の合成樹脂単体も
しくは低発泡体、等が使用できる。 Furthermore, the material is not limited to the above-mentioned low-foam polystyrene, but ABS resin, other synthetic resins alone, low-foam bodies, etc. can be used.
中桟１ｂと外枠１ａとの結合部境界に装飾布取
付板の裏面から切込み１ｃが形成され、当該切込
み部の前面は肉薄部１ｄとなつている。 A notch 1c is formed from the back surface of the decorative cloth mounting plate at the boundary of the joint between the middle crosspiece 1b and the outer frame 1a, and the front surface of the notch portion is a thin portion 1d.
第３図は実施例であつて、第１の切込み部１

徴を有する。 FIG. 3 shows an embodiment, in which the first notch 1
c' is provided inside the outer frame 1a, and the notch 1
A second notch 1e is provided in the outer frame 1a along the middle crosspiece 1b so that up to the part c′ is integrated with the middle crosspiece 1b, and when the cut portion 1c′ bends under the tension of the decorative fabric 2. , since the notch 1c' exists within the range of the outer frame 1a, the amount of deformation of the outer frame 1a as shown in FIG. 4b is smaller than that of the outer frame 1 of the embodiment shown in FIG. 4a.
It has the characteristics of being smaller than the deformation of a and having superior appearance.
