模块化声号筒和号筒阵列
摘要：
一种模块化号筒式扬声器和由模块化扬声器形成的模块化号筒阵列。声号筒包括第一声学模块。第一声学模块包括第一声学驱动器和用于传导来自第一声学驱动器的声能的第一声波导。第一声波导具有第一开口，声能通过该第一开口辐射。第一声波导以第一中心线为特征。第二声学模块包括第二声学驱动器和用于传导来自该声学驱动器的声能的第二声波导。第二声波导具有第二开口，声能通过该第二开口辐射。第二声波导以第二中心线为特征。第一模块和第二模块被配置成布置并保持在合适的位置，使得第一开口和第二开口对齐以形成基本上连续的衍射槽，并且使得第一中心线和第二中心线垂直于弧并且以多个角度中的第一角度相交。
摘要（英）：

A modular horn type loudspeaker and a modular horn array formed of modular loudspeakers. An acoustic horn includes a first acoustic module. The first acoustic module includes a first acoustic driver and a first acoustic duct, for conducting acoustic energy from the first acoustic driver. The first acoustic duct has a first opening through which acoustic energy is radiated. The first acoustic duct is characterized by a first centerline. A second acoustic module includes a second acoustic driver and a second acoustic duct, for conducting acoustic energy from the acoustic driver. The second acoustic duct has a second opening through which acoustic energy is radiated. The second acoustic duct is characterized by a second centerline. The first module and the second module are configured to be positioned and held in place so that the first and second openings are aligned to form a substantially continuous diffraction slot and so that the first and second centerlines are normal to an arc and intersect at a first one of a plurality of angles.
