Abstract
(EN) An acoustic adjusting material, a sound production apparatus, a filling method, and an electronic device. The acoustic adjusting material comprises an expandable high-molecular polymer filler containing styrene chain links and an acoustic improving filler, wherein the expandable high-molecular polymer filler containing the styrene chain links is foamed under a triggered condition to form a foam buffering filler, such that a buffering effect is provided for the acoustic improving filler during moving and collision; and the volume of the foamed expandable high-molecular polymer filler containing the styrene chain links changes along with changes in the temperature and/or foaming time, and when the temperature rises, damping is increased, and the buffering capacity is enhanced. In this way, the breakage risk of the acoustic improving filler is significantly reduced, the durability of the acoustic adjusting material is improved, and the service life of the acoustic adjusting material is prolonged.
(FR) Matériau de réglage acoustique, appareil de production de son, procédé de remplissage et dispositif électronique. Le matériau de réglage acoustique comprend une charge de polymère de poids moléculaire élevé expansible contenant des liaisons de chaîne de styrène et une charge d'amélioration acoustique, la charge de polymère de poids moléculaire élevé expansible contenant les liaisons de chaîne de styrène étant moussée sous une condition déclenchée pour former une charge de mise en tampon de mousse, de sorte qu'un effet de mise en tampon soit fourni pour la charge d'amélioration acoustique pendant le déplacement et la collision ; et le volume de la charge de polymère de poids moléculaire élevé expansible moussée contenant les liaisons de chaîne de styrène change avec des changements de température et/ou de temps de moussage, et lorsque la température augmente, l'amortissement est augmenté, et la capacité de mise en tampon est améliorée. De cette manière, le risque de rupture de la charge d'amélioration acoustique est significativement réduit, la durabilité du matériau de réglage acoustique est améliorée, et la durée de vie du matériau de réglage acoustique est prolongée.
(ZH) 一种声学调节材料、发声装置、填充方法及电子设备。声学调节材料包括:含有苯乙烯链节的可发性高分子聚合物填料和声学改善填料,所述含有苯乙烯链节的可发性高分子聚合物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,所述含有苯乙烯链节的可发性高分子聚合物填料发泡后的体积随温度和/或发泡时间的变化而变化,温度升高时阻尼增大,缓冲能力增强。通过这种方式,大大降低了声学改善填料破碎的风险,提高了声学调节材料的耐用性和使用寿命。
