本発明はスピーカーキャビネット用側として使用しうる
板材に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate material that can be used as a side for a speaker cabinet.
スピーカーギヤビネットにおいては、スピーカーに人力

をおこす。干渉をおこすと音に対しては好ましくないの
で、このスピーカー裏面より生ずる音波を吸収する目的
で、スピーカーキャビネットが使用される。In a speaker gear vignette, when a human power signal is applied to the speaker, the speaker's conductive paper vibrates, and sound waves travel both in the front direction of the speaker and in the rear direction, where the phase is delayed. Causes interference with traveling waves. Since interference is bad for sound, a speaker cabinet is used to absorb the sound waves generated from the back of the speaker.
従って、スピーカーキャビネットの伺料は、■裏面に生
じる音波を吸収することか必要であるほか、次の如き条
件が必要である。Therefore, the cost of a speaker cabinet must be 1) to absorb the sound waves generated on the back surface, and the following conditions must also be met.

り、ハウリングが牛じゃずいという欠点がある。■ The amplitude of the cabinet is small. ◎ When resonance occurs, it is damped completely. ◎ The r old 11 is large so that the cabinet does not vibrate. In general, speaker cabinets are made of solid wood made of natural wood. Heat curing of boards, plywood, and wood chips 1-1
Verticle hoards etc., which were built up in Miki 71f, are used, but they have low specific gravity, low rigidity, low internal gIS loss, and high resonance frequency. It has the disadvantage of being a cow.

:/Ijt1 is made of plastic mixed with a filler and is used in speaker boxes as it has a good balance of specific gravity, rigidity, and internal loss, and provides a more powerful sound with separation. However, unlike the plastic plates that have been put into practical use, the quality filler-containing plastic plates are dead and lacking in charm.
