    • PROBLEM TO BE SOLVED: To provide a "speaker device" including a magnetic circuit that is assembled with excellent workability and allowing each of components to be relatively easily recycled. SOLUTION: In the speaker device, a magnet 12, outer yokes 14, 15 and inner yokes 11, 13 configuring the magnetic circuit are combined to form a magnetic gap that a magnetic flux generated from the magnet crosses between the outer yokes 14, 15 and the inner yokes 11, 13, and a voice coil unit 18 connected to a diaphragm 21 is arranged in the magnetic gap. The speaker device includes positioning members 16a, 16b for positioning the inner yokes 11, 13 and the outer yokes 14, 15 magnetically coupled with the magnet 12 to form the magnetic gap.

    • PURPOSE:To improve waterproof, workability and physical characteristics by forming a synthetic resin coat layer at the surface of the laminated layer which laminates a polyamide resin to a diaphragm main body having a component of a natural fiber only or a natural fiber essentialy. CONSTITUTION:A diaphragm main body 4 mixing a synthetic fiber or a semisynthetic fiber is accommodated at the hole with a cone paper formed by paper making the natural fiber or the natural fiber in an accommodating an accommodating concave part 2b of a female mold 2 as a center, and in the upward direction, a polyamide resin film 5a is installed. Next, the film 5a is heated and softened and collides a male mold 3 for the female mold 2. After that, an air intake operation is executed from an intake port 2a and the vacuum condition is obtained, the air is sent by pressure from an air pressuring port 3a and the laminated layer 5 is formed on the upper surface of the diaphragm main body 4. Finally, on the surface of the laminated layer 5, a synthetic resin coat layer 6 is formed and the diaphragm 7 is obtained.
    • 目的:为了提高防水性,可加工性和物理特性,在层压层的表面形成合成树脂涂层,将聚酰胺树脂层合到仅具有天然纤维成分的天然纤维或天然纤维成分的隔膜主体上。 构成:将合成纤维或半合成纤维混合的隔膜主体4容纳在通过将天然纤维或天然纤维制成的锥形纸容纳在阴模2的容纳凹部2b中, 中心,并且向上方向安装有聚酰胺树脂膜5a。 接着,将膜5a加热软化,与阴模2的阳模3碰撞。之后,从进气口2a进行进气动作,得到真空条件, 在隔膜主体4的上表面上形成有空气压力端口3a和叠层5。最后,在叠层5的表面上形成合成树脂涂层6,并获得膜片7。
