Preparation method of composition, loudspeaker sound-absorbing material and manufacturing method of loudspeaker sound-absorbing material
The invention belongs to the technical field of material manufacturing, and particularly relates to a preparation method of a composition, a loudspeaker sound-absorbing material and a manufacturing method of the loudspeaker sound-absorbing material. The invention provides a preparation method of the composition, which comprises the following steps: mixing a porous material, a binder, a low-shrinkage additive and water to obtain mixed slurry, extruding the mixed slurry, shearing, and roasting to obtain a strip-shaped and/or rod-shaped product. The invention further provides a loudspeaker sound absorbing material and a manufacturing method thereof. According to the application, the porous material is of a three-dimensional structure formed by gathering the polyhedral holes in the space, has better mechanical strength, and is not easy to break after being vibrated; meanwhile, during high-frequency vibration, the three-dimensional structure can adsorb and desorb sound, reduce the resistance of the voice diaphragm, further reduce the resonant frequency F0, and effectively improve the acoustic performance. Through the selection of a specific porous material, the technical defects that in the prior art, a granular acoustic material affects the hearing feeling and the loudspeaker monomer is easily damaged when particles are broken are overcome.
本申请属于材料制造技术领域，尤其涉及一种组合物的制备方法及一种扬声器吸音材料、制造方法。本申请提供了一种组合物的制备方法，为：多孔材料、粘结剂、低收缩添加剂和水混合得混合浆料，混合浆料挤出后剪切、焙烧，得条状和/或棒状产品。本申请还提供了一种扬声器吸音材料及其制造方法。本申请中，多孔材料由多面体形状的孔洞在空间聚集形成三维结构，具有较好的机械强度，不易在受到震动后发生破碎；同时，在高频震动时，该三维结构可对声音进行吸附及脱附，降低音膜阻力，进一步降低谐振频率F0，有效提升声学性能；通过特定的多孔材料的选择，解决了现有技术中，颗粒型声学材料存在着影响听感以及颗粒破碎时易损坏扬声器单体的技术缺陷。
