Abstract: A waveguide configured to function as a high frequency waveguide for a high frequency sound source mounted to the waveguide, and to function as an acoustical low pass filter for a low frequency sound source mounted behind the waveguide in a multi-way loudspeaker system. The waveguide includes openings that overlay the vibrating surface of the low frequency source. The openings are configured by selection of various geometrical parameters to tailor filtering characteristics as desired.

Abstract: This invention provides a two-stage phasing plug located within a compression driver. The two-stage phasing plug housed within the compression driver may be coupled to a horn. The two-stage phasing plug includes first and second phasing plugs. The advantages of having a two-stage phasing plug is that the first and second phasing plugs may be simpler to manufacture, cost less and the overall dimensional tolerances may be tightly controlled. The higher dimensional tolerances may be obtained because the first phasing plug may be made from a unitary work-piece, and therefore, may be tooled and cut in the same machining set up. This allows the unitary work-piece to be machined and cut very accurately when compared to assembling separate components together during the manufacturing process. Since the most dimensionally critical area is the rear side of the first phasing plug, the tolerances of the second phasing plug may not be as critical. Thus, a more expensive material, such as steel, may be used for the first phasing plug, and less expensive material, such as plastic, may be used to manufacture the second phasing plug.

Abstract translation: 本发明提供一种位于压缩驱动器内的两级定相插头。 容纳在压缩驱动器内的两级定相插头可以连接到喇叭。 两级定相插头包括第一和第二定相插头。 具有两级定相插头的优点在于，第一和第二相位插头可以更容易制造，成本更低并且整体尺寸公差可以被严格控制。 可以获得更高的尺寸公差，因为第一相位插头可以由整体工件制成，因此可以在相同的机械加工中进行加工和切割。 与制造过程中将单独的部件组装在一起相比，这允许整体工件被加工和切割非常精确。 由于最大尺寸关键区域是第一定相插头的后侧，因此第二定相插头的公差可能不是至关重要的。 因此，诸如钢的更昂贵的材料可以用于第一定相插头，并且较便宜的材料（例如塑料）可用于制造第二定相插头。
