摘要： A loudspeaker vibrating diaphragm with has a foam layer and two un-foamed skin layers formed on both sides of the foam layer. The average foaming magnification including the foam layer and two un-foamed skin layers is 1.1-3.0. The average foaming magnification is the ratio of the thickness of the resin after foaming (which equals the sum of the thicknesses of the foamed layer and the two un-foamed layers) to the thickness of the resin before foaming. The foam layer contains foaming bubble cells which are formed with their longer axes arranged in the thickness direction of the diaphragm. The thickness of each un-foamed skin layer is 0.05-0.20 mm.

摘要： An acoustic diaphragm employed in a speaker or the like and a method for producing the acoustic diaphragm are disclosed. A diaphragm substrate is a diaphragm exhibiting air permeability such as a paper diaphragm. The substrate is processed with filling by microfibrilated pulp. For filling, the substrate is immersed in the liquid dispersion of the microfibrilated pulp and the pulp is deposited on the substrate under suction. When the microfibrilated pulp is deposited on the substrate under suction, any voids present in the substrate are closed by the microfibrilated pulp so that air tightness is improved without lowering the sound quality or detracting from desirable properties of the diaphragm, such as low density, high toughness and low losses.
摘要翻译：公开了一种在扬声器等中使用的声学隔膜以及用于制造声膜的方法。隔膜基板是表现透气性的隔膜诸如纸张隔膜的隔膜。用微纤维化纸浆填充底物。为了填充，将基板浸入微纤维化纸浆的液体分散体中，并且在抽吸下将纸浆沉积在基材上。当微纤维化纸浆在抽吸下沉积在基材上时，基质中存在的任何空隙都被微纤维化的纸浆封闭，使得气密性得到改善，而不降低声音质量或降低隔膜的期望性能，例如低密度，高韧性低损失。

摘要： The invention relates to a wide-band loudspeaker in which the overall diaphragm is divided into an inner and an outer diaphragm sub-area. The inner diaphragm sub-area preferably consists of a dome-shaped cover of the moving-coil support. The outer diaphragm sub-area can be formed as a cone or NAWI diaphragm or as a shaped or moulded body, the shaped body having an at least approximately planar front face and its rear boundary face having the form of a cone or NAWI diaphragm. The outer diaphragm sub-area is connected to the moving-coil support by a frequency-dependent yieldable connection with high damping which at high audiofrequencies practically decouples the outer diaphragm sub-area from the moving-coil support but at low audiofrequencies acts like a rigid connection.
摘要翻译：本发明涉及一种宽带扬声器，其中整个隔膜被分成内隔膜和外隔膜子区域。内隔膜子区域优选地由移动线圈支架的圆顶形盖子组成。外隔膜子区域可以形成为锥形或NAWI隔膜或成形或成型的本体，成形体具有至少近似平面的前表面，其后边界面具有锥形或NAWI隔膜的形式。外隔膜子区域通过具有高阻尼的频率依赖的可屈服连接而连接到动圈线圈支架，其在高音频频率下实际上将外隔膜子区域与动圈线圈支撑件分离，但是在低音频作用下，像刚性连接。

摘要： A diaphragm for use in an electro-acoustic transducer comprises a diaphragm main body only or mainly composed of natural fibers, a layer formed by laminating thereover a polyamide resin and a synthetic resin coating layer further formed to the surface of the laminate layer. The diaphragm is free from pin holes, exhibits satisfactory water proofness and excellent physical properties such as sonic propagation velocity inherent to the natural fibers. It can be fabricated with ease at a good yield and can reduce the fabrication cost.
