摘要： An audio speaker system employs an annular gasket that separates the sound reproducing membrane of a speaker driver with a horn waveguide. The annular gasket is disposed in an area outside of and adjacent to the throat of the horn waveguide. The annular gasket is preferably realized from closed cell foam or other compliant acoustically-absorbable material. The gasket minimizes the volume of the compression chamber that the sound reproducing membrane is compressing, thus leading to less frequency cancellation (which leads to improved frequency response of the speaker driver).
摘要翻译：音频扬声器系统采用将扬声器驱动器的声音再现膜与喇叭波导分离的环形垫片。环形垫片设置在喇叭波导管的喉部以外的区域中。环形垫片优选地由闭孔泡沫或其它柔顺的吸声材料实现。垫圈最小化声音再现膜正在压缩的压缩室的体积，从而导致较少的频率消除（这导致扬声器驱动器的频率响应的改善）。

摘要： A speaker system includes a speaker driver loaded by a horn waveguide. The speaker driver reproduces sound within an extended frequency range that includes a high frequency band between 8 kHz and 11 kHz. In the preferred embodiment, the extended frequency range includes a wide frequency band between 2 kHz and 11 kHz (and most preferably including the frequency band between 800 Hz and 11 kHz). The horn waveguide has an axi-symmetrical waveguide surface that provides uniform polar dispersion at dispersion angles greater than 90 degrees for sound within the extended frequency range. The waveguide surface preferably has an annular cross section with a radial dimension that increases curvilinearly from its throat to its mouth, such as a tractroid surface.

摘要： A projection screen is constructed of an open mesh fabric central portion for imaging a projected image, a sturdier border, and hanging hardware at each of the corners of the border. The central portion is constructed of a knit of multiple synthetic fibers twisted together and provides a screen with high diffusion. The open mesh provides substantial transparency to the screen when no image is being projected onto the screen permitting the screen to be used in a manner in which it will not act as a significant visual barrier when installed but not in use. The screen is mounted with hanging hardware that pulls the border and central portion taut. The screen when installed and taut has high diffusion and permits both front and rear projection with substantially equal brightness at both sides of the screen.
摘要翻译：投影屏幕由打开的网状织物中央部分构成，用于对投影图像，更坚固的边框进行成像，并在边框的每个角落处悬挂硬件。中心部分由多根合成纤维的针织物组成，并且提供具有高扩散的筛网。当没有图像投影到屏幕上时，打开的网格可以为屏幕提供实质的透明度，允许以安装但不使用的方式使其不会作为显着视觉屏障的方式使用屏幕。屏幕安装有悬挂的硬件，拉动边框和中央部分拉紧。安装和拉紧时的屏幕具有高扩散性，并且允许前屏幕和后投影器在屏幕两侧具有基本相等的亮度。
