| description | A composition for a ceramic speaker is provided. The composition for a ceramic speaker, according to one embodiment of the present invention, comprises: ceramics; sintering aids; and oxide-based additives containing Bi2O3. Therefore, the present invention can be sintered at the same time as an inner electrode while being thin, has excellent piezoelectric property so as to have excellent performance when applied to a speaker, and has high permittivity.
La présente invention concerne une composition pour un haut-parleur en céramique. La composition pour un haut-parleur en céramique, selon un mode de réalisation de la présente invention, comprend : des céramiques ; des auxiliaires de frittage ; et des additifs à base d'oxyde contenant du Bi2O3. Par conséquent, la présente invention peut être frittée en même temps qu'une électrode interne tout en étant mince, a une excellente propriété piézoélectrique de façon à avoir une excellente performance lorsqu'elle est appliquée à un haut-parleur, et a une permittivité élevée.
세라믹 스피커용 조성물이 제공된다. 본 발명의 일 실시예에 따른 세라믹 스피커용 조성물은 세라믹스, 소결조제 및 Bi2O3를 포함하는 산화물계 첨가제를 포함하여 구현된다. 이에 의하면, 박막화가 가능하면서도, 내부 전극과 동시 소결이 가능하며, 압전 특성이 우수하여 스피커 적용 시 성능이 우수하고, 유전율이 높은 효과가 있다. |
