のもあるが、これは非常にコスト高となるので、
高級品にしか使用されていない。 Low-priced amplifier casings of this type use a steel plate for the bottom plate. Although this is superior in terms of strength, it has the disadvantage of deteriorating the sound quality. Therefore, the bottom plate has been constructed of a material such as resin, but this has the disadvantage that the strength of the casing is reduced. Therefore, there are some cases where the entire chassis is made of non-magnetic material such as aluminum to maintain sufficient strength and not cause any deterioration in sound quality, but this is extremely costly, so
It is only used for luxury goods.
本考案は、上記事情にもとづいてなされたもの
で、ローコストを維持しながら音質の低下を防
ぎ、かつ、充分に強度を保つことができるアンプ
筐体の構造を提供しようとするものである。 The present invention was developed based on the above circumstances, and aims to provide an amplifier housing structure that can prevent deterioration of sound quality and maintain sufficient strength while maintaining low cost.

である。 For this purpose, the present invention provides that, when the bottom plate of the amplifier case is made of iron, the part of the bottom plate corresponding to the area where there is a lot of magnetic flux coming out from the high current line, electrolytic capacitor, transformer, etc. inside the amplifier case. , which is characterized by being made of non-magnetic material.
以下、本考案の実施例を図面を参照して具体的

上記底板２の部分２ａには特に窓を穿ち、非磁性
材料よりなる板片が取付けられている。 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1 denotes an amplifier housing, and its bottom plate 2 is entirely made of iron plate. Of the electrical components housed within the amplifier housing 1, windows are particularly cut in the portion 2a of the bottom plate 2 that corresponds to areas where a large amount of magnetic flux F escapes to the outside, such as large current lines, electrolytic capacitors, and transformers. , a plate made of non-magnetic material is attached.
上記非磁性材料には、ニツケルあるいはニツケ

それらのアルミ処理合板を用いてもよい。 Nickel, a nickel-copper alloy, or an alloy thereof may be used as the non-magnetic material. Alternatively, it may be simply copper or a copper alloy. Alternatively, a nonferrous metal plywood whose surface is treated with a copper material may be used. Furthermore, magnesium alloy, lead or its alloy, other non-magnetic electromagnetic shielding composite materials, resin, etc. may be used. Naturally, aluminum or its alloys, or aluminized plywood thereof may also be used.

できるという優れた実用上の効果を奏することが
できる。 In this way, corresponding to areas where magnetic flux is concentrated,
By locally configuring a part of the bottom plate of the iron plate with non-magnetic material, it practically prevents the sound quality from deteriorating without interfering with the escape of magnetic flux, and overall, the use of the iron plate significantly increases the cost. It can produce excellent practical effects in that it can avoid this problem, can be manufactured at low cost, and can maintain sufficient strength.
