    • PROBLEM TO BE SOLVED: To achieve a desired sound image localization and a spread feeling with a simple configuration speaker device not depending on only a diaphragm shape.SOLUTION: An acoustic diaphragm 201 made of a material having a physical anisotropy and formed in a predetermined shape, and an actuator 208 attached to the acoustic diaphragm 201 in order to excite a vibration component with a direction corresponding to a physical anisotropy taken into consideration are provided. Therefore, since the vibration component can be excited in the direction corresponding to the physical anisotropy, the sound wave surface shape and frequency characteristics of a sound pressure level radiated from the acoustic diaphragm 201 are changed to obtain a desired sound image localization and the spread feeling compared with an acoustic diaphragm made of material having a physical isotropy.
    • 要解决的问题:使用简单的配置扬声器装置来实现期望的声像定位和扩展感,而不仅仅取决于膜片形状。 解决方案:由具有物理各向异性并形成为预定形状的材料制成的声振膜201和附接到声振膜201的致动器208,以便以与取得的物理各向异性相对应的方向激发振动分量 提供了考虑。 因此,由于可以在与物理各向异性相对应的方向上激发振动成分,所以改变从声膜201辐射的声压级的声波表面形状和频率特性,以获得期望的声像定位和扩展感 与由具有物理各向同性的材料制成的声膜相比。 版权所有(C)2012,JPO&INPIT
