Sound-absorbing material, sound-generating device, and electronic apparatus
The invention discloses a sound absorbing material, a sound production device and electronic equipment. The sound-absorbing material comprises zeolite powder particles, structure reinforcing powder particles and an inorganic adhesive. The average particle size of the zeolite powder particles is greater than 10 microns, and the mass ratio of silicon to aluminum in the zeolite powder particles is less than 200; the structural reinforcing powder particles are made of a structural reinforcing material, and the particle size ratio of the structural reinforcing powder particles to the zeolite powder particles is 0.01-0.5; the inorganic adhesive is used for bonding the plurality of zeolite powder particles and the plurality of structural reinforcing powder particles into the sound-absorbing material, and the structural reinforcing powder particles are filled and bonded in structural gaps formed among the zeolite powder particles; and the crushing resistance of the sound absorbing material is 0.2 N to 10 N. The sound-absorbing material provided by the invention is formed by bonding the plurality of zeolite powder particles and the plurality of structural reinforcing powder particles through the inorganic adhesive, so that the sound-absorbing material has higher structural strength and is not easy to crush and deform in use, thereby improving the sound-absorbing effect of the sound-absorbing material and further improving the acoustic performance of the sound production device.
本发明公开了一种吸音材料、发声装置和电子设备。吸音材料包括沸石粉粒、结构补强粉粒和无机胶黏剂；沸石粉粒的平均粒径＞10μm，且沸石粉粒中的硅铝质量比＜200；结构补强粉粒采用结构补强材料制成，结构补强粉粒与沸石粉粒的粒径比为0.01～0.5；无机胶黏剂用于将多个沸石粉粒和多个结构补强粉粒粘结成吸音材料，且结构补强粉粒填充并粘接于各沸石粉粒之间形成的结构间隙中；吸音材料的抗压碎力为0.2N～10N。本发明提供的吸音材料通过无机胶黏剂将多个沸石粉粒和多个结构补强粉粒粘接而成，使得吸音材料具有更高的结构强度，在使用中不易发生碎粉和形变，从而可以提升了吸音材料的吸音效果，进而提升了发声装置的声学性能。
