Title:
ACOUSTIC ADJUSTING MATERIAL FOR SOUND PRODUCTION APPARATUS, SOUND PRODUCTION APPARATUS, FILLING METHOD AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/007334
Kind Code:
A1
Abstract:
Provided are an acoustic adjusting material for a sound production apparatus, the sound production apparatus, a filling method and an electronic device. The acoustic adjusting material comprises a buffer filler and an acoustic improvement filler. The buffer filler is foamed under a triggered condition to form a foamed body buffer filler so as to provide a buffer effect for the acoustic improvement filler during moving collision, and the volume of the foamed buffer filler is changed along with the change in temperature and/or foaming time, so that different buffer effects can be achieved. According to embodiments, the buffer degree of the buffer filler to the acoustic improvement filler during moving collision is flexibly controlled by means of the foaming temperature and time of the buffer filler. In the working process of the sound production device, the buffer filler greatly reduces the risk of breakage of the acoustic improvement filler, the durability of the acoustic adjusting material is improved, and the service lifetime of the acoustic adjusting material is prolonged.
