一种分子筛、包括该分子筛的扬声器箱及该分子筛的制备方法
摘要：
本发明涉及分子筛及扬声器，公开了一种分子筛，其具有MFI结构，包括骨架和骨架外阳离子，所述骨架包括SiO2和金属氧化物MxOy；所述骨架中Si/M原子比至少为50，其中M包含硼，所述骨架外阳离子为氢离子、碱金属离子或碱土金属中的至少一种。本发明还提供了一种包括该分子筛的扬声器箱和该分子筛的制备方法。本发明提供的分子筛、包括该分子筛的扬声器箱和该分子筛的制备方法，能够有效防止分子筛失效，提高扬声器的性能稳定性。
摘要（英）：

The invention relates to a molecular sieve and a loudspeaker enclosure, and discloses a molecular sieve. The molecular sieve comprises an MFI structure, wherein the MFI structure comprises a frameworkand outer cation ions of the framework; the framework comprises SiO2 and a metallic oxide MxOy; the ratio of Si atom to M atom in the framework is at least 50; M includes boron; the outer cation ionsof the framework are at least one type of hydrogen ions, alkali metal ions or alkaline-earth metal. The invention further provides a loudspeaker enclosure comprising the molecular sieve and a preparation method of the molecular sieve. According to the molecular sieve, the loudspeaker enclosure with the same and the preparation method of the molecular sieve, the molecular sieve is effectively prevented from failure; the performance stability of the loudspeaker can be improved.
