Zusammenfassung:Provided is a ceramic speaker composition. A ceramic speaker composition according to an embodiment of the present invention comprises a ceramic, a sintering aid, and an oxide-based additive containing Bi2O3. According to the present invention, the composition can be formed into a thin film, can be co-sintered with internal electrodes, and has excellent piezoelectric properties, and thus has the effects of exhibiting excellent performance and a high dielectric constant when applied to speakers. L'invention concerne une composition de haut-parleur en céramique. Une composition de haut-parleur céramique selon un mode de réalisation de la présente invention comprend une céramique, un adjuvant de frittage et un additif à base d'oxyde contenant Bi2O3. Selon la présente invention, la composition peut être transformée en film mince, peut être cofrittée avec des électrodes internes et possède d'excellentes propriétés piézoélectriques, ce qui lui permet de présenter d'excellentes performances et une constante diélectrique élevée lorsqu'elle est appliquée à des haut-parleurs. 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.
