Abstract
A reflector disperses the audio waves from a loudspeaker acoustic source in a substantially 180 degree pattern. The reflector, coupled with a speaker, forms a loudspeaker system producing a wide dispersion of audio waves in a listening area. The reflector can be adjusted to alter the direction of the dispersal pattern in the listening area.
Claims28
A reflector for distributing audio waves in a substantially 180 degree dispersal pattern from a diaphragm speaker propagating the audio waves along a substantially single axis into a listening area comprising:
- a flat back wall substantially parallel to and laterally spaced from said axis;
- a reflecting surface from which said audio waves reflect directly into said listening area connected to said back wall, said reflecting surface having a leading edge connected to said back wall near said speaker, said leading edge approximately intersecting said axis;
- and
- a trailing edge connected to said back wall and said reflecting surface, said trailing edge encompassing an area greater than an area of said speaker.
A loudspeaker system for distributing audio waves into a listening area in a substantially 180 degree dispersal pattern comprising:
- an acoustic source comprised of at least one diaphragm speaker capable of propagating audio waves along a substantially single axis;
- a reflector, comprised of a flat back wall substantially parallel to and laterally spaced from said axis, a reflecting surface from which said audio waves reflect directly into said listening area connected to said back wall, said reflective surface having a leading edge connected to said back wall near said acoustic source, said leading edge approximately intersecting said axis, and a trailing edge connected to said back wall and said reflecting surface, said trailing edge encompassing an area greater than an area of said acoustic source;
- and
- means to acoustically couple said acoustic source to said reflector.
A reflector for distributing audio waves in a substantially 180 degree dispersal pattern from a diaphragm speaker propagating the audio waves along a substantially single axis wherein the reflector is programmable to adjust a direction of the dispersal pattern comprising:
- a flat back wall substantially parallel to and laterally spaced from said path;
- a reflecting surface connected to said back wall, said reflecting surface having a leading edge connected to said back wall near said speaker, said leading edge approximately intersecting said axis;
- and
- a trailing edge connected to said back wall and said reflecting surface, said trailing edge encompassing an area greater than an area of said speaker;
- a support plate positioned parallel to back wall and opposite said reflecting surface;
- a tensioning device disposed between said plate and said back wall;
- and
- adjusting means connecting said back wall and said support plate for rendering said back wall non-parallel to said support plate.
