摘要： A loudspeaker for acoustic enclosure, in particular a tweeter or a medium-frequency loudspeaker, which consists of a spherical diaphragm with direct radiation, with a front side that is concave in relation to the spool, and onto which is attached at a certain level, for example at mid-height or approximately at mid-height, the moving spool so as to achieve an optimal mechanical coupling capable of reproducing frequencies lower than 1 kHz with a high efficiency. Material such as pure beryllium or a Be/Al alloy or similar alloys is used to make the diaphragm.Loudspeakers of the tweeter or medium type, especially for very high-fidelity acoustic enclosures.

摘要： The invention relates to a membrane (1) for a loudspeaker, characterised in that: it has a core (2) consisting of structural mousse which is very precisely cut and thermoformed to the desired geometric profile for the membrane; the external face (4) of the membrane is covered by at least one, preferably a plurality of, outer folds (5) of woven or nonwoven fibres impregnated with resin, forming a laminated material or outer skin (6); the inner face (7) of the membrane is covered or not by at least one inner fold (8) of woven or non-woven fibres impregnated with resin, forming a laminated material or an inner skin (9). Essentially the same results are obtained in terms of rigidity, but the invention creates a large difference based on the process for controlling the resin content and the polymerisation cycle. Ultimately, the stability of the characteristics is improved.
摘要翻译：本发明涉及一种用于扬声器的膜（1），其特征在于：它具有由结构的摩丝组成的芯（2），其被非常精确地切割并热成型为膜的所需几何轮廓; 膜的外表面（4）由浸渍有树脂的织造或非织造纤维的至少一个，优选多个外部折叠（5）覆盖，形成层压材料或外皮（6）; 膜的内表面（7）被至少一个浸渍有树脂的织造或非织造纤维的内折叠（8）覆盖，形成层压材料或内皮（9）。在刚性方面基本上获得相同的结果，但是本发明基于用于控制树脂含量和聚合循环的方法产生大的差异。最终，特性的稳定性得到提高。
