摘要： To give solution to a problem that a fire-retarded speaker component has a high hygroscopicity and thus exhibits deteriorated acoustic properties, the speaker component undergoes strength drop, elastic modulus drop and internal loss due to fire retardant and the increase of the number of treatment steps adds to manufacturing cost. A speaker component formed by a paper product including a triphenyl phosphate fire retardant is used.

摘要： It is an object of the present invention to ensure that when a speaker diaphragm having an adequate fire resistance is to be obtained, it is possible to ensure stability of various characteristics and thus avoid a deterioration of an audio characteristic of the speaker device. An expansive graphite is mixed/milled with at least one of a natural fiber, a chemical fiber, an inorganic fiber, a synthetic fiber and the like consisting of different fibers selected from the foregoing fibers (step of mixing/milling a fiber with an expansive graphite), thereby obtaining a paper slurry. The paper slurry is adjusted and heated at an adequate molding temperature necessary for the expansive graphite to expand, thereby effecting milling and molding (milling/molding step) and thus obtaining a milled material serving as a diaphragm substrate having a fire resistant layer formed by a heated expansion of the expanding agent. The diaphragm substrate is then dipped in a liquid containing a fire resistant component (step of dipping the diaphragm substrate in a liquid containing a fire resistant component), followed by a drying step (drying the diaphragm substrate) and a finishing step (cutting the diaphragm substrate in accordance with desired inner and outer diameters), thereby obtaining a desired speaker diaphragm having a sufficient fire resistance.
摘要翻译：本发明的目的是确保在获得具有足够的耐火性的扬声器振膜时，可以确保各种特性的稳定性，从而避免扬声器装置的音频特性的恶化。将膨胀石墨与天然纤维，化学纤维，无机纤维，合成纤维等中的至少一种混合/研磨，所述天然纤维，合成纤维等由选自上述纤维的不同纤维构成（将纤维与膨胀剂混合/研磨的步骤石墨），从而获得纸浆。在膨胀石墨膨胀所需的适当成型温度下对纸浆进行调整和加热，从而进行研磨和模制（研磨/模制步骤），从而获得用作具有耐火层的碾磨材料，该耐磨层由膨胀剂的膨胀膨胀。然后将隔膜基板浸入含有耐火部件的液体（将隔膜基板浸入含有耐火成分的液体的步骤）中，然后进行干燥步骤（干燥隔膜基板）和精加工步骤（切割隔膜基板，根据期望的内径和外径），从而获得具有足够耐火性的所需扬声器隔膜。

摘要： A speaker diaphragm is formed from a material combining a fiber-type material and a ceramic-type-coating agent including metal alkoxide, metal hydroxide, and a colloidal or fine-particulate inorganic substance. The combining process for the ceramic-type-coating agent is performed before or after the fiber-type material is formed into a shape of the diaphragm.
