【考案の詳細な説明】
本考案は空気クツシヨンの吸音材を有するスピ
ーカボツクスに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker box having an air cushion sound absorbing material.
従来、スピーカボツクスの吸音材には再生綿又
は再生ナイロン等が使用されていた。これらの吸
音材をスピーカボツクスの内壁に貼付していたが
吸音特性は吸音材自身の大きさ、厚み等で決つて
おり、自由に変えることができない欠点があつ
た。 Conventionally, recycled cotton or recycled nylon has been used as the sound absorbing material for speaker boxes. These sound-absorbing materials were attached to the inner walls of speaker boxes, but the sound-absorbing properties were determined by the size, thickness, etc. of the sound-absorbing material itself, which had the disadvantage that it could not be changed freely.
本考案は上記欠点を取除く為に考案されたもの
で、図面に示す実施例いついて説明すれば、第１
図に示すごとく、密閉ボツクス１の前部に複数個
のスピーカ６，７を取付け、後部内壁と吸音材２
に囲まれた空気室３と密閉ボツクス１外の空気タ
ンク４内とを導通管５で連絡せるスピーカボツク
スである。 The present invention was devised to eliminate the above-mentioned drawbacks, and the first embodiment will be described with reference to the embodiment shown in the drawings.
As shown in the figure, a plurality of speakers 6 and 7 are attached to the front part of the closed box 1, and the rear inner wall and sound absorbing material 2
This is a speaker box in which an air chamber 3 surrounded by a closed box 1 is connected to the inside of an air tank 4 outside a closed box 1 through a conduction pipe 5.
本考案は上記のような構造になつているので、
密閉ボツクス後部の空気室３による空気クツシヨ
ンと空気タンク４内の空気量により自由自在に吸
音特性を変えることにより、スピーカボツクスよ
り放音される音質の向上をはかる優れた考案であ
る。 Since the present invention has the structure described above,
This is an excellent idea that improves the sound quality emitted from the speaker box by freely changing the sound absorption characteristics by the air cushion provided by the air chamber 3 at the rear of the sealed box and the amount of air in the air tank 4.
