    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 inorganic or organic filler in an amount of 3 to 30 % by weight is added to a resin containing a foaming agent. The resulting resin mixture material is injection molded into a loudspeaker diaphragm (1) having a three-layer structure in which a foamed layer (3) is covered with unfoamed skin layers (2). For forming the three-layer structure, a resin mixture material of polypropylene containing a foaming agent is injected into a cavity of a mold (20). Immediately after the injection and the completion of forming the skin layers (2), the mold (20) is separated so that the material may start foaming at its inside to form the foamed layer (3). Since the surfaces of the resin mixture material are in contact with the inner surfaces of the mold in the injection, the surfaces of the resin mixture material have solidified before the foaming takes place, so as to form the unfoamed skin layers (2). By adjusting the filler to the appropriate content, the loudspeaker diaphragm (1) is improved in appearance quality while keeping the other physical properties with favourable characteristics.

    摘要: An organic electroluminescent display device includes an organic electroluminescent element (10) formed on a substrate (1) thereof and having an organic compound layer group sandwiched between cathodes (6) and anodes (2). The organic compound layer group has laminated electroluminescence functional layers formed of at least one kind of organic compound. Further, the organic electroluminescent display device includes an airtight case (10) that encloses the organic electroluminescent element with a space formed between the airtight case itself and the organic electroluminescent element and isolates the organic electroluminescent element from outside air, and a filler gas filling the space within the airtight case. The filler gas contains at least one kind of combustion supporting gas.
