Abstract
(EN) An acoustic conditioning material, a sound production apparatus, a filling method, and an electronic device. The acoustic conditioning material comprises an expandable buffer filler and an acoustic improvement filler; the expandable buffer filler is foamed under a triggered condition to form a foam buffer filler, so as to provide a buffer effect when the acoustic improvement filler is moved and collided; and the volume of the foamed expandable buffer filler varies with the change in temperature and/or foaming time.
(FR) L'invention concerne un matériau de conditionnement acoustique, un appareil de production de son, un procédé de remplissage et un dispositif électronique. Le matériau de conditionnement acoustique comprend une charge tampon expansible et une charge d'amélioration acoustique ; la charge tampon expansible est moussée dans une condition activée pour former une charge tampon en mousse, de façon à fournir un effet tampon lorsque la charge d'amélioration acoustique est déplacée et soumise à des chocs ; et le volume de la charge tampon expansible en mousse varie en fonction du changement de température et/ou de temps de moussage.
(ZH) 一种声学调节材料、发声装置、填充方法及电子设备,该声学调节材料包括可发性缓冲填料和声学改善填料,所述可发性缓冲填料在被触发的条件下进行发泡,成为泡沫体缓冲填料,以对所述声学改善填料在移动碰撞时提供缓冲作用,所述可发性缓冲填料发泡后的体积随温度和/或发泡时间的变化而变化。
