A low-frequency improvement material and a speaker system applying the same

Abstract

A low-frequency improvement material is disclosed and includes a plurality of zeolite granules including a plurality of zeolite particles including a plurality of zeolite crystal particles. The zeolite crystal particles include a skeleton and positive ions outside the skeleton. The skeleton includes SiO2 and an oxide MxOy containing an element M. The average crystal particle size of the zeolite crystal particles is 5-75 nm. The invention further provides a speaker system applying the low-frequency improvement material. The material and the system can achieve further improved performance of thesystem, reduction in disabled molecular sieve, and improvement in performance stability of the system.

Description

【Technical field】 [0001] Embodiments of the present invention relate to the technical field of low-frequency improving materials, and in particular to a low-frequency improving material and a speaker system using the low-frequency improving material. 【Background technique】 [0002] With the development of science and technology and the improvement of living standards, people have higher and higher requirements for the performance of the speaker system. Especially, for mobile phone speaker systems, it is required to provide excellent acoustic performance while keeping the volume as small as possible. Due to the increasingly compact volume of consumer electronics, the volume left for the speaker system’s rear cavity is getting smaller and smaller. Recently, low-frequency improvement materials such as activated carbon and zeolite are introduced into the rear cavity to increase the volume of the virtual rear cavity and improve the low-frequency performance of the speaker system....

AI Technical Summary

Problems solved by technology

[0003] However, because the loudspeaker system emits a small amount of various VOCs in the actual environment, the performance of the low-frequency improvement material deteriorates. Especially recently, the integration of electronic consumer products is getting higher and higher, and the system is becoming more and more complex. The components and amount of VOCs that can be emitted are increasing It is difficult to predict and control, and the requirements for the environmental stability of low-frequency improved materials resistant to complex VOCs are becoming more and more stringent
