摘要： A bobbin for an electro- acoustic driver includes an outer surface, a substantially planar surface at an end of the bobbin, and a bobbin axis that is substantially coaxial with a housing axis. The bobbin is disposable inside a housing and configured to move along the bobbin axis. The substantially planar surface at the end of the bobbin is securable to an acoustic diaphragm. The bobbin includes one or more of (a) legs extending from the outer surface to the substantially planar surface, (b) a wall which extends about substantially all of a perimeter of the planar surface, and (c) a plurality of through holes in the substantially planar surface.

摘要： A tool for arranging voice coil leadouts in a microspeaker comprises a mandrel having a top surface on which a bobbin and voice coil are positioned during formation of helicoidal leadout regions of the voice coil, a bobbin alignment feature for positioning at an inner diameter of the bobbin; a sleeve alignment element at a bottom region of the bobbin alignment feature, the sleeve alignment element having a first surface on which a sleeve of the microspeaker is positioned during the formation of the helicoidal leadout regions, and a gluing ring positioned about the mandrel and on a second surface of the sleeve alignment element for providing guide paths for distal ends of the leadout end regions extending in a direction from the mandrel to the sleeve alignment element.

摘要： A method of forming a device having a compliant member (16) includes creating a membrane (22) having one or more elastomeric layers which are at least partially cured. Another elastomeric layer (26) is provided on the membrane (22) in an uncured state. A bobbin (30) and a housing (28) are positioned so that an end of the bobbin or housing, or the ends of both the bobbin and housing, extend at least partially into the uncured elastomeric layer (26). The uncured elastomeric layer (26) is then cured to secure it to the membrane (22) and to the housing (18) or bobbin (30), or both the housing and bobbin. The method substantially reduces or eliminates the formation of holes that can form during fabrication or use of the device.
摘要翻译：一种形成具有柔性构件（16）的装置的方法包括形成具有一个或多个至少部分固化的弹性体层的膜（22）。另一弹性体层（26）以未固化状态设置在膜（22）上。线轴（30）和壳体（28）被定位成使得线轴或壳体的端部或线轴和壳体的端部至少部分地延伸到未固化的弹性体层（26）中。然后固化未固化的弹性体层（26）以将其固定到膜（22）和壳体（18）或线轴（30）上，或固定到壳体和线轴上。该方法大大减少或消除了在制造或使用该装置期间可形成的孔的形成。
