声换能器
摘要：
本发明提出一种声换能器(1)，包括膜片罐形件(3)、换能器元件(16)和壳体，其中，所述膜片罐形件(3)具有膜片(2)和壁(4)。所述膜片罐形件(3)的所述膜片(2)、所述壁(4)和至少一个壳体部分(6)一件式地构型为纤维塑料复合构件(7)，其中，所述纤维塑料复合构件(7)的至少一个第一区域(10)是以纤维增强的并且所述纤维塑料复合构件(7)的至少一个第二区域(11)是无纤维的，使得在所述纤维塑料复合构件(7)中的波在从所述至少一个第一区域(10)至所述至少一个第二区域(11)的过渡部处至少部分地被反射。
摘要（英）：

A sound transducer (1) is proposed, comprising a diaphragm cup (3), a transducer element (16) and a housing, wherein the diaphragm cup (3) comprises a diaphragm (2) and a wall (4). The diaphragm (2),the wall (4) of the diaphragm cup (3) and at least one housing part (6) are formed in one piece as a fibre-plastic composite component (7), wherein at least one first region (10) of the fibre-plasticcomposite component (7) is reinforced with fibres and at least one second region (11) of the fibre-plastic composite component (7) is free of fibres, and so in the fibre-plastic composite component (7) waves are at least partially reflected at a transition from the at least one first region (10) to the at least one second region (11).
