本発明は高弾性繊維を補強材として熱硬化性樹脂を9f
定形状に積層してなるスピーカー用ホーンに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes a thermosetting resin with high elasticity fiber as a reinforcing material.
This invention relates to a speaker horn formed by laminating layers in a regular shape.

キシ樹脂等の熱硬化性樹脂が用いられていた。Conventionally, zinc, aluminum, or an alloy thereof, or a thermoplastic resin such as vinyl chloride resin or ABS resin, or a thermosetting resin such as phenol resin or epoxy resin has been used as a horn material for a speaker.

が小さいだめに十分な強度が得られないばかりでなく、
ホーンの共振周波数が低い周欧数に下シ、聴感上悪影響
を与え−る欠点かあった。The former has the drawback that either the Young's modulus is large and sufficient strength can be obtained, or the internal loss is small, resulting in large horn resonance, which significantly impairs sound quality. In the latter case, the internal 4p loss is relatively large and the resonance of the horn is suppressed to some extent, or the Young's modulus is small, so not only is sufficient strength not obtained.
The disadvantage was that the horn had a low resonant frequency, which had a negative impact on the audibility.
本発明はこのような従来欠点を改良したもので、以下に
説明する。The present invention improves on these conventional drawbacks, and will be explained below.

用いられる。The high modulus fibers used as reinforcing materials in the present invention include glass fibers, carbon fibers, silicon carbide fibers, aluminum F fibers, boron/tungsten fibers, aromatic holamide fibers (aramid fibers), and various high modulus fiber reinforcements. As a material,
Woven fabrics made of single fibers of high modulus fibers or bundles of multiple fibers used as warp and weft threads, or single fibers that are cut into predetermined dimensions or evenly distributed in no direction. Nonwoven fabrics stacked to a predetermined thickness and hardened with a binder are used.
本発明における熱硬化性樹脂とは、不飽和ポリエステル
樹脂、エポキシ樹脂、フェノール樹脂などである。Thermosetting resins in the present invention include unsaturated polyester resins, epoxy resins, phenol resins, and the like.
以下、本発明の一定施例を説明する。Certain embodiments of the invention will now be described.

積層する。・Next, spread a glass fiber non-woven fabric (Surf Ace Mat) on top of a horn mold made of metal, wood or resin, apply the above-mentioned unsaturated polyester resin mixture to the non-woven fabric with a brush to impregnate it, and use a rubber spatula or roller to impregnate it. Defoaming. On top of that, spread a non-woven fabric (mat) and repeat the same process to form a second layer.Furthermore, spread a woven fabric (roving cloth) on top of that, and then repeat the same process to form a multilayer. Laminate.

を害することがない。The speaker horn manufactured as described above is made of polyester wood reinforced with high elastic fiber reinforcement.
Since the fat is laminated in multiple layers, as shown in Table K below,
The internal loss is almost the same as that made of polyester resin, and the Young's modulus is about 3.3 times higher. Therefore, according to this embodiment, the resonance of the horn is not suppressed to the same extent as that of a resin speaker horn, but the resonance frequency of the horn is shifted to a sufficiently high frequency, so that hearing sense is not impaired.
