Waveguide for a boat
A waveguide mounted in the area beneath the helm of a boat directs acoustic output from one or more loudspeakers to its windshield where the sound can be contained, reinforced and directed toward the entertainment areas of the boat.
1. A waveguide for delivering acoustic output from a loudspeaker to a windshield which overlies the helm of a boat, comprising:
a housing having a hollow interior, said housing being foi lied with an acoustic inlet opening and at least one acoustic outlet opening;
an adaptor coupled to said acoustic inlet opening, said adaptor being effective to mount a loudspeaker in position outside of said hollow interior, said loudspeaker directing its acoustic output through said adaptor and through said acoustic inlet opening into said hollow interior of said housing;
a mounting bracket which mounts said housing to the helm of the boat, said mounting bracket having at least one bracket opening which aligns with said at least one acoustic outlet opening of said housing, said mounting bracket and said housing being positioned on the helm of the boat so that acoustic output from said loudspeaker is directed to the windshield of the boat whose slope redirects said acoustic output toward the aft end of the boat.
2. The waveguide of claim 1 in which said adaptor is located at one end of said housing, said adaptor having a peripheral edge mounted to the frame of the loudspeaker.
3. The waveguide of claim 1 in which said housing has a front wall, a back wall, a bottom wall, a top wall and opposed end walls interconnected to form said hollow interior, said top wall being formed with said at least one acoustic outlet opening.
4. The waveguide of claim 3 in which said at least one acoustic outlet opening comprises two acoustic outlet openings separated by a divider formed in said top wall of said housing.
5. The waveguide of claim 3 in which one of said end walls of said housing is formed with said acoustic inlet opening.
6. The waveguide of claim 1 further including a projection extending from said at least one bracket opening in said mounting bracket in position to mount within said at least one acoustic outlet opening in said housing.
7. The waveguide of claim 3 further including a drain tube connected to said bottom wall of said housing.
8. The waveguide of claim 1 further including a trim piece mounted to the helm of the boat over said mounting bracket.
