Title
(EN) Acoustic adjusting material, sound production device, filling method and electronic equipment
(ZH) 声学调节材料、发声装置、填充方法及电子设备
Abstract
(EN) The embodiment of the invention provides an acoustic adjusting material, a sound production device, a filling method and electronic equipment. The acoustic adjusting material comprises an expandable buffer filler and an acoustic improvement filler, wherein the expandable buffer filler is foamed under a triggered condition to formed a foam buffer filler so as to provide a buffer effect for the acoustic improvement filler during moving collision, and the volume of the foamed expandable buffer filler is changed along with the change of the temperature and/or the foaming time. According to the embodiment of the invention, the foaming temperature and time of the expandable buffer filler are used for flexibly controlling the buffer degree of the expandable buffer filler to the acoustic improvement filler during moving collision. In the working process of the sound production device, the expandable buffer filler greatly reduces the risk of breaking of the acoustic improvement filler, improvesthe durability of the acoustic adjusting material and prolongs the service lifetime of the acoustic adjusting material.
(ZH) 本申请实施例提供了一种声学调节材料、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。本申请实施例通过所述可发性缓冲填料发泡的温度和时间来灵活控制其对所述声学改善填料在移动碰撞时的缓冲程度。在发声装置工作过程中,可发性缓冲填料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。
