Abstract

A mobile stereo speaker unit and assembly includes a central speaker for reproducing both left and right stereo sound channels. The central speaker is in a well in the central portion of the front panel of a vehicle, and a reflector is positioned above the speaker to intercept the sound and reflect it in a desired direction. The direction is selectable vertically or horizontally depending on the particular reflector used and the reflected sound may be directed towards the rear or towards the front windshield.

Claims

1. A mobile speaker set for use in a vehicle having a front panel, comprising left and right speakers adapted to be embedded in a front panel of a vehicle on the left and right sides respectively, a central speaker adapted for carrying left and right channel stereo signals and to be embedded in an opening in a central location of the front panel, and a reflector provided in the sound emanating path of said central speaker for selectively directing the further sound path of said sound after reflection therefrom, wherein said reflector has a top planar plate positioned above said central speaker, a semi-cylindrical portion extending from said opening above said central speaker to said planar plate, and a vertical separator panel dividing said reflector into at least two portions, each portion reflecting the sound from said central speaker horizontally but at diverse angles within said vehicle.

2. The invention of claim 1, wherein said reflector is positioned to reflect said sound rearwardly in said vehicle.

3. The invention of claim 1, wherein said reflector is positioned to reflect said sound frontwardly in said vehicle to further reflect off a front windshield of the vehicle.

4. The invention of claim 1, wherein said reflector is horizontally rotatable about a vertical axis running through the center line of said central speaker.

5. A mobile stereo speaker assembly for a vehicle having a front panel and a front windshield;

said speaker assembly comprising,

a central speaker connected for producing sound of left and right stereo channels, said speaker being positioned facing upwards within a well in said front panel; and

an adjustable sound reflector positioned on said panel above said speaker and being adjustable to selectively direct reflected sound therefrom which emanates from said speaker, wherein said reflector has a top planar plate positioned above said central speaker, a semi-cylindrical portion extending from said well above said central speaker to said planar plate, and a vertical separator panel dividing said reflector into at least two portions, each portion reflecting the sound from said central speaker horizontally but at diverse angles within said vehicle.

6. The invention of claim 5, wherein said reflector is positioned to reflect said sound rearwardly in said vehicle.

7. The invention of claim 5, wherein said reflector is positioned to reflect said sound frontwardly in said vehicle to further reflect off said front windshield of the vehicle.

8. The invention of claim 5, wherein said reflector is horizontally rotatable about a vertical axis running through the center line of said central speaker.

9. A mobile speaker set for use in a vehicle having a front panel, comprising left and right speakers adapted to be embedded in a front panel of a vehicle on the left and right sides respectively, a central speaker adapted for carrying left and right channel stereo signals and to be embedded in an opening in a central location of the front panel, and a reflector provided in the sound emanating path of said central speaker for selectively directing the further sound path of said sound after reflection therefrom, wherein said reflector is a planar reflector hinged to a rear edge of said opening and pivotable about said hinge to control the vertical direction of said sound path and to direct said sound toward a front windshield of the vehicle.

10. A mobile stereo speaker assembly for a vehicle having a front panel and a front windshield;

said speaker assembly comprising,

a central speaker connected for producing sound of left and right stereo channels, said speaker being positioned facing upwards within a well in said front panel; and

an adjustable sound reflector positioned on said panel above said speaker and being adjustable to selectively direct reflected sound therefrom which emanates from said speaker, wherein said reflector is a planar reflector hinged to a rear edge of said well and pivotable about said hinge to control the vertical direction of said sound path and to direct said sound toward said front windshield of the vehicle.
