Problems solved by technology

[0003] However, the density of the existing polycarbonate shell is relatively high, and the general density range is 1.35-1.55g / cm 3 , leading to a large mass of the shell, causing the weight of the sounding device to be too large, which affects the consumer's sense of use; and the benzene ring structure in the polycarbonate molecular chain has high rigidity and large steric hindrance, resulting in polycarbonate The melt viscosity of the material is high, the fluidity is poor, and it is difficult to form thin-walled products

Abstract

The embodiment of the invention provides a shell for a sound production device and the sound production device, the shell comprises a plastic component and a reinforcing component, the plastic component comprises syndiotactic polystyrene, the range of the mass fraction of the syndiotactic polystyrene is 40-90, and the range of the mass fraction of the reinforcing component is 5-50. The shell comprises a plastic component and a reinforcing component, the plastic component comprises syndiotactic polystyrene, the range of the mass fraction of the syndiotactic polystyrene is 40 to 90 parts, and the range of the mass fraction of the reinforcing component is 5 to 50 parts. Through the cooperation of the low density of the syndiotactic polystyrene and the high strength of the reinforcing component, the shell has the characteristics of high strength, low density, small deformability and high assembly precision, and the aim of light weight of the shell is achieved.

Description

technical field [0001] The present application belongs to the technical field of acoustic components, and in particular, the present application relates to a housing for a sound-generating device and a sound-generating device. Background technique [0002] Existing housings for sound-generating devices are mostly made of plastic, for example, the housings of the sound-generating devices are formed by injection molding of polycarbonate. Polycarbonate has the advantages of high temperature resistance and good impact performance, and can provide good protection for sound devices. [0003] However, the density of the existing polycarbonate shell is relatively large, and the general density range is 1.35-1.55g / cm 3 , resulting in the large mass of the shell, resulting in the excessive weight of the sounding device, affecting the consumer's sense of use experience; and the benzene ring structure in the molecular chain of the polycarbonate has high rigidity and large steric hindra...
