Abstract
This invention relates to a loudspeaker having at least one sound collecting tubes attached to the rear of the speaker frame or the sound collecting tubes forming the speaker frame for collecting and directing sound waves emitted from the rear of the speaker diaphragm. The sound collecting tube is particularly useful for directing and boosting sound waves emitted from the rear of the speaker which is otherwise dissipated or absorbed by the loudspeaker housing material or insulation. In addition, conventional or specialized sound horns may be readily attached to the outlet end of the sound collecting tubes which can direct sound waves emitted by the speaker to any desired direction.
Claims22
A sound collecting and directing device for use with a loudspeaker having a diaphragm with a frontal side which generally faces an ambient surrounding and a back side which faces opposite the frontal side;
- a frame means which operatively supports the diaphragm and a speaker driving means, the frame means having a flange at its outermost peripheral edge;
- and a plurality of sound venting cut-outs in the frame means to permit sound waves to substantially freely pass therethrough, said device comprising:
- a sound collecting tube having an inlet tube and an outlet end, said inlet end having a flange means for attaching to the flange of the frame means to attach said inlet end to the frame means to shroud said inlet end over at least one of the cutouts in the frame means and means for isolating the speaker driving means from the sound traveling path in said sound collecting tube;
- and
- a sound concentrating and directing horn means formed at said outlet end of said sound collecting tube,
- wherein said sound collecting tube is for collecting sound emitting from the back side of the diaphragm and directing into said horn means.
A sound collecting and directing device for use with a loudspeaker having a diaphragm with a frontal side which generally faces an ambient surrounding and a back side which faces opposite the frontal side;
- a frame means for operatively supporting the diaphragm and a speaker driving means, the frame means having a flange at its outermost peripheral edge;
- and at least two sound venting cut-outs in the frame means, which permit sound waves to substantially freely pass therethrough, said device comprising:
- a sound collecting tube having an inlet end and an outlet end, said inlet end having a flange means for attaching to the flange of the frame means to attach said inlet end to the frame means to shroud said inlet end over at least one of the cut-outs in the frame means and means for isolating the speaker driving means from the sound traveling path in said sound collecting tube;
- and
- a sound concentrating and directing horn means formed at said outlet end of said sound collecting tube,
- wherein said sound collecting tube is for collecting sound emitting from the back side of the diaphragm and directing into said horn means.
A loudspeaker system comprising:
- a) a loudspeaker comprising:
- a diaphragm with a frontal side which generally faces an ambient surrounding and a back side which faces opposite said frontal side;
- a speaker driving means operatively connected to said diaphragm to cause said diaphragm to vibrate;
- a frame means for operatively supporting said diaphragm and said speaker driving means, said frame means having a flange at its outermost peripheral edge;
- and
- at least two sound venting cut-outs in said frame means to permit sound waves to substantially freely pass therethrough, and
- b) a sound collecting and directing device formed on said frame means, said device comprising:
- a sound collecting tube having an inlet end and an outlet end, said inlet end having a flange means for attaching to said flange of said frame means to attach said inlet end to said frame means to shroud said inlet end over at least one of said cut-outs in said frame means and means for isolating the speaker driving means from the sound traveling path in said sound collecting tube;
- and
- a sound concentrating and directing horn means formed at said outlet end of said sound collecting tube,
- wherein said sound collecting tube collects sound emitted from the back side of said diaphragm and directs into said horn means.
