  • Patent number: 5937073
    Abstract: The present invention provides a speaker mounted within a speaker enclosure. The speaker enclosure provides a sidewall defining an interior space sufficient for enclosing the speaker, and a grille is mounted on an open end of the speaker enclosure. A pair of electrically conducting wires connect a speaker electrode to an electrical binding post mounted on an enclosing back wall of the speaker enclosure, providing an electrical connection between the speaker and an outside source. A hanger is pivotally engaged with the speaker enclosure such that the speaker enclosure is positionable over a range of downwardly directed angles relative to the hanger. The invention includes a breather hole that provides ventilation between the grille and the interior space of the enclosure. This ventilation allows the speaker to vibrate for maximum sound quality, while also excluding dust from the speaker enclosure.
