Abstract

An enclosure for one or more loudspeakers includes a housing having a top panel, a bottom panel, a front panel, a back panel and opposed end panels collectively defining a hollow interior which is open at an aperture formed in one of the panels. A baffle is mounted within the housing interior which supports one or more loudspeakers and forms a port to direct sound radiating from the back of the speakers to the aperture. All of the panels, and at least the portion of the baffle which is visible through the aperture, are covered with carpeting to provide a finished appearance for mounting of the enclosure within the interior of a vehicle.

Claims

1. An enclosure for use with a loudspeaker which radiates sound in a first direction and in a second direction generally opposite to said first direction, comprising:

a housing including a top panel, a bottom panel, a front panel, a back panel and opposed side panels interconnected to collectively form a hollow interior, said front panel being formed with an aperture;

a baffle structure located within said hollow interior of said housing, including;

(i) a front wall connected to said bottom panel and to each of said side panels of said housing, said front wall being spaced from said front panel of said housing and being adapted to mount at least one loudspeaker in a position to direct sound radiating therefrom in said first direction toward said aperture;

(ii) a back wall located between said front wall and said back panel of said housing, said back wall extending between said side panels of said housing;

(iii) a top wall connected to said front wall and said back wall, said top wall extending between said side panels and being spaced from said top panel of said housing;

said baffle forming a port for the transmission of sound radiating in said second direction from the at least one loudspeaker to said aperture in said front panel of said housing.

2. The enclosure of claim 1 in which a first space is formed between said back wall of said baffle and said back panel of said housing, and a second space is formed between said top wall of said baffle and said top panel of said housing, said first and second spaces forming said port.

3. The enclosure of claim 2 in which said baffle further includes a bottom wall connected to said back wall and extending between said side panels of said housing.

4. The enclosure of claim 3 in which a third space is formed between said bottom wall of said baffle and said bottom panel of said housing, said first, second and third spaces forming said port.

5. An enclosure for use with a loudspeaker which radiates sound in a first direction and in a second direction generally opposite to said first direction, comprising:

a housing including a top panel, a bottom panel, a front panel, a back panel and opposed side panels interconnected to collectively form a hollow interior, said front panel being formed with an aperture;

a baffle structure located within said hollow interior of said housing, including;

(i) a front wall connected to said bottom panel and to each of said side panels of said housing, said front wall being spaced from said front panel of said housing;

(ii) a back wall spaced from said back panel and extending between said side panels of said housing;

(iii) an intermediate wall connected to said bottom panel and located between said front wall and said back wall, said intermediate wall being adapted to mount at least one loudspeaker in a position to direct sound radiating therefrom in a first direction toward said front wall;

(iv) a top wall connected to said front wall, said intermediate wall and said back wall and extending between said side panels of said housing, a closed cavity being formed by said top wall, front wall, intermediate wall, opposed side panels and bottom panel which receives sound radiating in said first direction from the at least one loudspeaker;

said baffle forming a port for the transmission of sound radiating in said second direction from the at least one loudspeaker to said aperture in said front panel of said housing.

6. The enclosure of claim 5 in which a first space is formed between said back wall of said baffle and said back panel of said housing, and a second space is formed between said top wall of said baffle and said top panel of said housing, said first and second spaces collectively forming said port.

7. The enclosure of claim 6 in which said baffle further includes a bottom wall connected to said back wall and extending between said side panels of said housing.

8. The enclosure of claim 7 in which a third space is formed between said bottom wall of said baffle and said bottom panel of said housing, said first, second and third spaces collectively forming said port.
