摘要： A modularized loudspeaker enclosure having an open-ended enclosure body, a loudspeaker support at one open end and an end structure at the other end. The enclosure body can be modified to alter the volume of the enclosure. A finally assembled enclosure can be sealed or ported. In one embodiment, the enclosure body includes a cylindrical tube cut to a length that provides a desired volume. In another embodiment the enclosure comprises standard corner, wall and end structures that constitute a component set for a constant length enclosure that can have different cross section areas.

摘要： A compound driver acoustic transducer. A frame supports a motion generator to one side of two diaphragms. An intermediate diaphragm is continuous and is driven by the motion generator. The intermediate diaphragm forms a closed volume with a solid portion of the frame that opens into a central opening through the other, open diaphragm. An axially rigid coupling connects the two diaphragms so they operate in unison.

摘要： A hand tightenable connector provides a high pressure seal between a first element and a second element. A first female element includes a recess for supporting a compressible O-ring and a second male element includes a ferrule which deforms the O-ring in the recess when the male and female elements are mated. The ferrule abuts against the surface defining the opening of the O-ring recess so that a high pressure seal is effected between the first and second elements without severely distorting the O-ring. The connector may be used to couple various components of a high pressure fluid delivery system such as are found in a jet cutting system.
摘要翻译：可手动拧紧的连接器在第一元件和第二元件之间提供高压密封。第一阴元件包括用于支撑可压缩O形环的凹部，并且第二阳元件包括当公阳元件配合时使凹部中的O形环变形的套圈。套圈抵靠限定O形环凹部的开口的表面，使得在第一和第二元件之间实现高压密封，而不会严重扭曲O形环。连接器可以用于联接诸如在喷射切割系统中发现的高压流体输送系统的各种部件。

摘要： An electronic linear motor particularly for use with loudspeakers includes first and second annular counterfacing air gaps centered on a motor axis. An armature and spider carry first and second voice coils in the first and second annular air gaps, respectively. A rigid link connects the armature and an output device, such as a loudspeaker cone. A releasable coupling attaches either or both ends of the rigid link to an adjacent armature or output device.

摘要： A dual-cone loudspeaker includes a primary speaker cone and an axially displaced secondary speaker cone mounted to the back of a magnet structure. A rigid link causes both cones to move in unison. The rigid link includes an open support structure with equiangularly extending spokes that form a central hub. A ring circumscribes the spokes and ataches to the first speaker cone. A rigid element connects to the spokes and the secondary speaker cone so the primary and secondary speaker cones move in unison and improve the bass response for the loudspeaker. The rigid coupling device is also adapted to support a high frequency radiator to extend the overall loudspeaker frequency response into higher frequencies.
