Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] The present invention provides a zeolite particle (not shown), the particle size of the zeolite particle is 10 μm to 100 μm, which includes a plurality of zeolite particles and an auxiliary agent, and the auxiliary agent is used to bind the plurality of zeolite particles to combine together. In this embodiment, the particle size of the zeolite particles is more preferably 28 μm to 100 μm. The structure of the zeolite particles includes at least one of MEL, MFI, FER, *BEA, DDR, *-EWT, ISV, *-ITN, ITH, -SVR, and IHW structures. This structure realizes the microporous absorption and desorption sound absorption of zeolite particles and the traditional structural sound absorption (porous sound absorption).

[0035] Specifically, in this embodiment, the zeolite particles are hydrophobic, and the proportion of the zeolite particles in the zeolite part...

Abstract

The invention discloses a zeolite particle. The zeolite particle comprises a plurality of zeolite particle bodies and auxiliaries, and the auxiliaries are used to bond the plurality of zeolite particle bodies together, and the particle diameters of the zeolite particles are in a range from 10 (mu)m to 100 (mu)m. The invention also provides the production method of the zeolite particle. Compared with the prior art, the zeolite particle produced by adopting the production method of the zeolite particle is advantageous in that an effect of lowering low frequency is more obvious, and the low frequency performance of the loudspeaker adopting the zeolite particle is better.

Description

technical field [0001] The invention relates to the field of acoustics, in particular to a zeolite particle and a preparation method thereof. Background technique [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. At present, the functions of mobile phones are extremely diverse, one of which is the function of high-quality music. Therefore, speaker boxes for playing sound are widely used in current smart mobile devices. [0003] The speaker box in the related art includes a lower cover, an upper cover that is combined with the lower cover to form a storage space, and a sound unit housed in the storage space, the sound unit and the upper cover form a front cavity, the sounding unit and the lower cover form a rear cavity, and the upper cover and the lower cover also form an auxiliary sounding cavity commun...
