    摘要: A loudspeaker having a magnetizable pole piece, a voice coil member surrounding the pole piece with a portion of magnetic gap and connected to a vibratable diaphragm, and a damper supporting the voice coil member, is characterized in that an elastic member is provided between the pole piece and the voice coil member in the magnetic gap wherein an elastic member is made of an elastic material having an elastic constant substantially 1.5 times or more than that of the damper. In addition, the elastic material is made of a silicone rubber.

    摘要: An internal magnetic circuit is formed by a plate (20) forming a pole piece, a vertically magnetized magnet (21) attached to a bottom face of the plate, and a yoke (22) attached to a bottom face of the magnet. A magnetic gap (G 0 ) is formed between the plate and the yoke. The yoke includes a bottom part (22b) attached to the bottom face of the magnet, a side part (22c) standing on the side of the plate, and a folded-back part(22d) folding downwards over the side part to face the magnetic gap. Thus, the internal magnetic circuit having a uniform magnetic flux density inside the magnetic gap along the direction of its length is provided.

    摘要: An EL display panel comprises a plurality of insulating substrates (10) which are aligned side by side. Each substrate has an elongated first side surface (11) and an opposite second side surface (18), a plurality of discrete electrodes (20) formed on the first side surface (11), a common electrode (30) formed on the second side surface (12), and a plurality of luminescent elements (40) formed on a top surface (13) of the substrate (10). The discrete electrodes (20) of the adjacent substrates are electrically connected with each other.
