【考案の詳細な説明】
この考案は少なくとも１個のスピーカをそれぞ
れ備えた少なくとも２個のキヤビネツトが相互に
連結されたスピーカ装置における連結部分の改良
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a connecting part in a speaker device in which at least two cabinets, each having at least one speaker, are interconnected.
従来、上記スピーカ装置においては、２個のキ
ヤビネツトを回動自在に連結する手段として、最
も簡便な構造として、キヤビネツトの対向面にお
いて挿通したボルトおよびナツトによるものが考
えられている。 Conventionally, in the above-mentioned speaker device, the simplest structure for rotatably connecting two cabinets has been considered to be a bolt and nut inserted through opposing surfaces of the cabinets.
そして当該ボルトには一方のキヤビネツトのみ
に備えられた入力ターミナルと他方のキヤビネツ
トに備えられたスピーカとを接続するためのリー
ド線を挿通するための貫通孔が設けられている。 The bolt is provided with a through hole through which a lead wire for connecting an input terminal provided in only one cabinet and a speaker provided in the other cabinet is inserted.
このようなスピーカ装置においては次のような
欠点を有していた。 Such speaker devices have the following drawbacks.
すなわち、前記貫通孔を通じてキヤビネツト相
互が音響的に結合されるので一方のキヤビネツト
に固定されたスピーカの動作に伴う背圧で他方の
キヤビネツトに固定されたスピーカの振動板が影
響を受け混変調歪が発生する。 That is, since the cabinets are acoustically coupled through the through hole, the back pressure caused by the operation of the speaker fixed to one cabinet will affect the diaphragm of the speaker fixed to the other cabinet, resulting in cross-modulation distortion. Occur.
又前記貫通孔が音響管として作用する結果、特
定の周波数で共鳴しスピーカ装置の周波数特性が
平坦でなくなる欠点を有していた。 Furthermore, as the through-hole acts as an acoustic tube, it resonates at a specific frequency, resulting in a drawback that the frequency characteristics of the speaker device become uneven.
この考案はこのような欠点を解決するため考案
したスピーカ装置であつて、以下実施例について
更に詳細に説明する。 This invention is a speaker device devised to solve these drawbacks, and examples thereof will be described in more detail below.
第１図において、１はスピーカ装置であつてス
ピーカ２ａ，２ｂがそれぞれ固定されたキヤビネ
ツト１ａ，１ｂが対向面において貫通したボルト
３および当該ボルト３に螺合したナツト４により
回動自在に連結されている。 In FIG. 1, reference numeral 1 denotes a speaker device in which cabinets 1a and 1b to which speakers 2a and 2b are respectively fixed are rotatably connected by a bolt 3 passing through the opposing surfaces and a nut 4 screwed into the bolt 3. ing.

よび５ｂとスピーカ２ｂはリード線６ａおよび６
ｂにより、又スピーカ２ａと前記入力ターミナル
５ａおよび５ｂはリード線７ａおよび７ｂにより
それぞれ接続されている。 5a and 5b are a pair of input terminals provided on the rear surface of one of the cabinets (cabinet 1b in the figure), and the input terminals 5a and 5b and the speaker 2b are connected to lead wires 6a and 6.
b, and the speaker 2a and the input terminals 5a and 5b are connected by lead wires 7a and 7b, respectively.
そして前記リード線７ａおよび７ｂは独立気泡
を有する発泡体８が充填されたボルトの貫通孔３
ａを通じてキヤビネツト１ｂよりキヤビネツト１
ａ内に導入される。 The lead wires 7a and 7b are connected to the bolt through-hole 3 filled with a foam 8 having closed cells.
from cabinet 1b to cabinet 1 through a.
introduced into a.
具体的には第２図に示すように、リード線７ａ
および７ｂにその径が貫通孔３ａ径より適宜大と
なるように独立気泡を有する発泡体シート８を巻
きつけ、貫通孔３ａに圧入すればよい。 Specifically, as shown in FIG.
A foam sheet 8 having closed cells is wound around the foam sheet 7b so that its diameter is appropriately larger than the diameter of the through hole 3a, and the foam sheet 8 is press-fitted into the through hole 3a.
このような構成によれば、発泡体８は独立気泡
を有するので空気の流通が遮断されキヤビネツト
１ａ内空間と１ｂ内空間との音響的結合を防止す
ることができる。 According to this configuration, since the foam 8 has closed cells, air circulation is blocked and acoustic coupling between the interior space of the cabinet 1a and the interior space of the cabinet 1b can be prevented.
したがつて、両スピーカ２ａ，２ｂはそれぞれ
全く独立して動作するので相互の干渉による混変
調を防止でき、かつ音響管としての作用も防止で
きるので、混変調歪のない、かつ周波数特性の平
坦なスピーカ装置を提供することができる。 Therefore, since both speakers 2a and 2b operate completely independently, it is possible to prevent cross-modulation due to mutual interference and prevent them from acting as an acoustic tube, so there is no cross-modulation distortion and the frequency characteristics are flat. It is possible to provide a speaker device with a wide range of functions.
尚、実施例においては、発泡体シートを巻きつ
ける構成であるが大量生産の観点からすればリー
ド線を圧入して挿通する小孔を有する円筒状に成
形した発泡体を用意することが望ましい。 In the embodiment, a foam sheet is wound around the structure, but from the viewpoint of mass production, it is desirable to prepare a cylindrical foam having a small hole through which a lead wire is press-fitted.
