    • A speaker mounting system comprising a speaker housing configured to house a speaker, a wall mount configured to be mechanically fastened to a wall, and one or more adjustment pieces actuatably connecting the speaker housing to the wall mount. The adjustment pieces may comprise a first adjustment piece fixed to the wall mount and a second adjustment piece slidably and rotatably attached to the first adjustment piece and pivotally attached to the speaker housing. The second adjustment piece may be configured to laterally slide toward and away from the wall mount and to rotate about a first axis and the speaker housing may be configured to rotate or pivot relative to the second adjustment piece about a second axis perpendicular to the first axis. The speaker mounting system may also comprise a biasing member and locking mechanism for selectively allowing and preventing rotation about the first and second axes.

    • A coaxial speaker system that minimizes detrimental sound wave reflections from its high frequency speaker. The coaxial speaker system includes a high frequency speaker coaxially mounted within a low frequency speaker. The high frequency speaker includes a sound reproducing membrane, a voice coil assembly and magnet assembly for actuating the sound reproducing membrane in response to an electrical audio signal, and optionally a wave guide horn for directing sound waves produced by the sound reproducing membrane. The wave guide horn has a throat disposed adjacent the sound reproducing membrane and a mouth disposed opposite the throat. The low frequency speaker also includes a sound reproducing membrane assembly and a voice coil assembly and magnet assembly for actuating the sound reproducing membrane assembly in response to an electrical audio signal. At least a portion of the low frequency speaker sound reproducing membrane assembly is positioned adjacent the mouth of the wave guide horn (or adjacent the outer edge of the high frequency speaker sound reproducing membrane when no horn is provided) to inhibit the detrimental effects of sound waves produced by the high frequency speaker that reflect off the low frequency speaker.
    • 一种同轴扬声器系统,可将来自其高频扬声器的有害声波反射最小化。 同轴扬声器系统包括同轴安装在低频扬声器内的高频扬声器。 高频扬声器包括声音再现膜,音圈组件和用于响应于电音频信号致动声音再现膜的磁体组件,以及可选地用于引导由声音再现膜产生的声波的波导喇叭。 波导喇叭具有邻近声音再现膜设置的喉部和与喉部相对设置的嘴。 低频扬声器还包括声音再现膜组件和用于响应于电音频信号致动声音再现膜组件的音圈组件和磁体组件。 低频扬声器声音再现膜组件的至少一部分位于波导喇叭的嘴部附近(或者当没有提供喇叭时与高频扬声器声音再现膜的外边缘相邻)定位,以抑制声音的不利影响 由高频扬声器产生的反射低频扬声器的波形。
