Sound-absorbing particles, preparation method thereof and loudspeaker
The invention relates to the field of acoustics, in particular to sound-absorbing particles, a preparation method thereof and a loudspeaker. The sound-absorbing particles are formed by combining a molecular sieve and an adhesive, and each sound-absorbing particle comprises a first flat surface, a second flat surface and an arc-shaped side edge, wherein the first flat surface and the second flat surface are symmetrically distributed, and the arc-shaped side edge is connected with the first flat surface and the second flat surface; wherein the ratio of the molecular sieve to the adhesive is 1: (0.02-0.1) in terms of components. The sound-absorbing particles provided by the invention have a smaller longitudinal size under the same volume, the path of gas entering the sound-absorbing particles is shorter, and more gas molecules can be adsorbed or desorbed in a short time, so that the sound-absorbing particles have a better sound-absorbing effect; the sound-absorbing particles are filled in the rear cavity of the loudspeaker, so that the acoustic performance of the loudspeaker can be remarkably improved.
本发明涉及声学领域，尤其涉及一种吸音颗粒及其制备方法以及扬声器。所述吸音颗粒由分子筛和胶黏剂组合而成，所述吸音颗粒包括对称分布的第一扁平面和第二扁平面以及连接所述第一扁平面和所述第二扁平面的弧形侧边；其中，所述分子筛和所述胶黏剂的比例以组份计为1：（0.02~0.1）。本发明提出的吸音颗粒的在相同体积下具有更小的纵向尺寸，气体在进入吸音颗粒内部时路径更短，可以在短时间内吸附或脱附更多的气体分子，从而具有更好的吸音效果，将吸音颗粒填充于扬声器的后腔中可以显著提高扬声器的声学性能。
