Two-way loudspeaker for vehicle

Claim 2

A combination speaker assembly for use in a vehicle comprising an annular housing having a peripheral wall with an opening therein and having first and second open ends, a first speaker for reproducing audio mid frequencies and audio high frequencies mounted essentially within said housing in alignment with said opening to project the output of said first speaker out of said housing through said opening, and a second speaker for reproducing audio low frequencies mounted adjacent to said first open end and outside of said housing to inject the output of said second speaker into said housing and past said first speaker and out said second open end, the acoustical axis of said first speaker being arranged essentially normal to the acoustical axis of said second speaker and in use being directed essentially toward the ears of the listener.

Claim 3

The combination speaker and assembly set forth in claim 1, wherein the plane of said opening in said housing is essentially perpendicular to the planes of said first and second open ends.

Claim 4

The combination speaker assembly set forth in claim 1, wherein said first speaker is a dynamic exponential horn.

Claim 5

The combination speaker assembly set forth in claim 3, wherein said exponential horn has a frequency response in the range from 1200 Hz. to about 20 KHz.

Claim 6

The combination speaker assembly set forth in claim 1, wherein said second speaker is a woofer.

Claim 7

The combination speaker assembly set forth in claim 5, wherein the frequency response of said woofer is in the range from about 35 Hz. and up.

Claim 8

The combination speaker assembly set forth in claim 1, wherein the acoustical axes of said first speaker and said second speaker are laterally offset with respect to each other.

Claim 9

The combination speaker assembly set forth in claim 1, and further comprising an acoustically transparent grille covering said second open end.

Claim 10

The combination speaker assembly set forth in claim 8, wherein said grille is a sheet of foamed plastic.

Claim 11

A combination speaker assembly for use in a vehicle comprising an annular housing having a peripheral wall with an opening therein and having first and second open ends, a first speaker for reproducing audio mid frequencies and audio high frequencies mounted essentially within said housing in alignment with said opening to project the output of said first speaker out of said housing through said opening, a second speaker for reproducing audio low frequencies mounted adjacent to said first open end and outside of said housing to inject the output of said second speaker into said housing and past said first speaker and out said second open end, the acoustical axis of said first speaker being arranged essentially normal to the acoustical axis of said second speaker and in use being directed essentially toward the ears of the listener, and a balancing control mounted on said housing to adjust the balance between the output of said first speaker and said second speaker.

Claim 12

A combination speaker assembly for use in a vehicle comprising an annular housing having a peripheral wall with an opening therein and having first and second open ends, a first speaker for reproducing audio mid frequencies and audio high frequencies mounted essentially within said housing in alignment with said opening to project the output of said first speaker out of said housing through said opening, a second speaker for reproducing audio low frequencies mounted adjacent to said first open end and outside of said housing to inject the output of said second speaker into said housing and past said first speaker and out said second open end, the acoustical axis of said first speaker being arranged essentially normal to the acoustical axis of said second speaker and in use being directed essentially toward the ears of the listener, and a balancing control mounted on said housing to adjust the balance between the output of said first speaker and said second speaker.

Claim 13

The combination speaker assembly set forth in claim 10, wherein said balancing control is mounted in said housing adjacent to said opening.

Claim 14

A combination speaker assembly for mounting in a vehicle on a panel having an aperture therein and with one surface thereof disposed toward a listener and the other surface thereof disposed toward a large acoustical chamber, said combination speaker assembly comprising an annular housing having a peripheral wall with an opening therein and having first and second open ends, means mounting said housing upon the first surface of an associated panel with said first open end in general alignment with the aperture in the panel, a first speaker for reproducing audio mid frequencies and audio high frequencies mounted essentially within said housing in alignment with said opening to project the output of said first speaker out of said housing through said opening, and a second speaker for reproducing audio low frequencies mounted within the associated acoustical chamber on the other side of the associated panel and outside of said housing and adjacent to said first open end to inject the output of said second speaker into said housing and past said first speaker and out said second open end, the acoustical axis of said first speaker being arranged essentially normal to the acoustical axis of said second speaker and in use being directed essentially toward the ears of the listener.

Claim 15

A combination speaker assembly for mounting in a vehicle on a panel having an aperture therein and with one surface thereof disposed toward a listener and the other surface thereof disposed toward a large acoustical chamber, said combination speaker assembly comprising an annular housing having a peripheral wall with an opening therein and having first and second open ends, means mounting said housing upon the first surface of an associated panel with said first open end in general alignment with the aperture in the panel, a first speaker for reproducing audio mid frequencies and audio high frequencies mounted essentially within said housing in alignment with said opening to project the output of said first speaker out of said housing through said opening, and a second speaker for reproducing audio low frequencies mounted within the associated acoustical chamber on the other side of the associated panel and outside of said housing and adjacent to said first open end to inject the output of said second speaker into said housing and past said first speaker and out said second open end, the acoustical axis of said first speaker being arranged essentially normal to the acoustical axis of said second speaker and in use being directed essentially toward the ears of the listener.
