摘要：【中文】本发明公开了一种新型超薄多媒体扬声器及其工作方法，包括扬声器，扬声器包括磁罩及与磁罩组配围成收纳空间的支架和球顶，磁罩与支架之间相互卡合，且相互间隙之间设有磁钢，自磁钢由上而下依次设有极片与带管音圈；采用钕铁硼作为永磁场提供源，以减小高度空间需求；采用片型弹波，同时采用片状膜片设计以取代传统的锥形音盆组件，以降低高度空间的要求和限制振幅，满足失真需求，与现有技术相比，本发明通过二次转向将不同方向上的壳体支架最终转换成生产加工用的同一方向，方便工作人员将元件放入至壳体支架中进行组装，提高了效率，且不需要人工转向，使工人能更加专心地对扬声器进行组装。 【EN】The invention discloses a novel ultrathin multimedia loudspeaker and a working method thereof, wherein the loudspeaker comprises a magnetic cover, a bracket and a dome, wherein the bracket and the dome form a containing space by being combined with the magnetic cover; neodymium iron boron is used as a permanent magnetic field supply source to reduce the height space requirement; compared with the prior art, the loudspeaker assembly has the advantages that the shell supports in different directions are finally converted into the same direction for production and processing through secondary steering, so that a worker can conveniently put elements into the shell supports for assembly, the efficiency is improved, manual steering is not needed, and the loudspeaker can be assembled by the worker more intensely.

摘要：【中文】本发明公开了一种扬声器用膜片材料的制备方法，包括下列步骤：S1、制备聚对苯二甲酸乙二醇酯薄膜，聚对苯二甲酸乙二醇酯薄膜的孔径为10～30nm；S2、采用聚氨酯泡棉胶带将步骤S1得到的所述聚对苯二甲酸乙二醇酯薄膜与聚酰亚胺薄膜胶合；S3、进行阵列式热压，使热压辊压合部分的所述聚对苯二甲酸乙二醇酯薄膜与聚酰亚胺薄膜直接焊接在一起，得到复合膜片材料。本发明的扬声器用膜片材料通过热压，使得每层基材薄膜连接更为紧密，提高膜片整体抗疲劳能力和耐高温能力，防止膜片材料试验后分层，能通过高温、高功率等高强度测试的能力；具有良好的强度等力学性能，阻尼减振效果好，振动内部损失较小，失真小，音质好，使用寿命长。 【EN】The invention discloses a preparation method of a diaphragm material for a loudspeaker, which comprises the following steps: s1, preparing a polyethylene terephthalate film, wherein the aperture of the polyethylene terephthalate film is 10-30 nm; s2, gluing the polyethylene terephthalate film obtained in the step S1 with a polyimide film by adopting a polyurethane cotton adhesive tape; and S3, carrying out array type hot pressing to directly weld the polyethylene terephthalate film and the polyimide film at the press-fit part of the hot pressing roller together to obtain the composite film sheet material. According to the diaphragm material for the loudspeaker, each layer of base material film is connected more tightly through hot pressing, the integral fatigue resistance and high temperature resistance of the diaphragm are improved, the diaphragm material is prevented from layering after a test, and the capability of high-strength tests such as high temperature and high power can be passed; the damping vibration attenuation structure has the advantages of good mechanical properties such as strength, good damping vibration attenuation effect, small vibration internal loss, small distortion, good sound quality and long service life.
