Abstract

A loudspeaker arrangement comprises a mid-range loudspeaker arranged in a dashboard of a vehicle, a first tweeter arranged adjacent to the mid-range loudspeaker in the dashboard of the vehicle, and a second tweeter arranged adjacent to the mid-range loudspeaker in the dashboard of the vehicle. The mid-range loudspeaker is arranged between the first tweeter and the second tweeter. The mid-range loudspeaker is a non-directional loudspeaker that radiates sound towards a driver's seat and towards a passenger seat in equal parts. The first tweeter is a directional loudspeaker that radiates sound primarily towards the passenger seat, and the second tweeter is a directional loudspeaker that radiates sound primarily towards the driver's seat.

First claim

The invention claimed is:

1. A loudspeaker arrangement comprising:
a mid-range loudspeaker arranged in a dashboard of a vehicle;
a first tweeter arranged adjacent to the mid-range loudspeaker in the dashboard of the vehicle; and
a second tweeter arranged adjacent to the mid-range loudspeaker in the dashboard of the vehicle, wherein
the mid-range loudspeaker is arranged between the first tweeter and the second tweeter,
the mid-range loudspeaker is a non-directional loudspeaker that radiates sound towards a driver's seat and towards a passenger seat in equal parts,
the first tweeter is a directional loudspeaker that radiates sound primarily towards the passenger seat, and
the second tweeter is a directional loudspeaker that radiates sound primarily towards the driver's seat,
wherein the first tweeter and the second tweeter are each arranged at a distance of no more than 10 cm
a third tweeter and a fourth tweeter, wherein
the third tweeter is arranged distant to the mid-range loudspeaker on a first side of the mid-range loudspeaker,
the fourth tweeter is arranged distant to the mid-range loudspeaker on a second side of the mid-range loudspeaker that is opposite to the first side,
the third tweeter is a directional loudspeaker that radiates sound primarily towards the passenger seat, and
the fourth tweeter is a directional loudspeaker that radiates sound primarily towards the driver's seat, and

wherein:
the first tweeter is arranged closer to the passenger seat than to the driver's seat, and
the second tweeter is arranged closer to the driver's seat than to the passenger seat, such that a main radiation lobe of the first tweeter and a main radiation lobe of the second tweeter do not intersect.

2. The loudspeaker arrangement of claim 1 , wherein the mid-range loudspeaker has a circular cross-section, and wherein the first tweeter and the second tweeter each have a rectangular cross-section.

3. The loudspeaker arrangement of claim 1 , wherein
the third tweeter is arranged at a distance of at least 50 cm from the mid-range loudspeaker, and
the fourth tweeter is arranged at a distance of at least 50 cm from the mid-range loudspeaker.

4. The loudspeaker arrangement of claim 3 , wherein the third tweeter and the fourth tweeter each are either mounted to or in the dashboard of the vehicle or coupled to an A-pillar of the vehicle.

5. A loudspeaker arrangement comprising:
a mid-range loudspeaker arranged in a center console of a vehicle;
a first tweeter arranged adjacent to the mid-range loudspeaker in the center console of the vehicle; and
a second tweeter arranged adjacent to the mid-range loudspeaker in the center console of the vehicle, wherein
the mid-range loudspeaker is arranged between the first tweeter and the second tweeter,
the mid-range loudspeaker is a non-directional loudspeaker that radiates sound towards a first rear seat and a second rear seat in equal parts,
the first tweeter is a directional loudspeaker that radiates sound primarily towards the first rear seat, and
the second tweeter is a directional loudspeaker that radiates sound primarily towards the second rear seat,
wherein the first tweeter and the second tweeter are each arranged at a distance of no more than 10 cm from the mid-range loudspeaker, and
a third tweeter and a fourth tweeter, wherein
the third tweeter is arranged distant to the mid-range loudspeaker on a first side of the mid-range loudspeaker,
the fourth tweeter is arranged distant to the mid-range loudspeaker on a second side of the mid-range loudspeaker that is opposite to the first side,
the third tweeter is a directional loudspeaker that radiates sound primarily towards the first rear seat, and
the fourth tweeter is a directional loudspeaker that radiates sound primarily towards the second rear seat, and

wherein:
the first tweeter is arranged closer to a front passenger seat than to a driver's seat, and
the second tweeter is arranged closer to the driver's seat than to the front passenger seat, such that a main radiation lobe of the first tweeter and a main radiation lobe of the second tweeter do not intersect.

6. The loudspeaker arrangement of claim 5 , wherein the third tweeter and the fourth tweeter each are either mounted to or in a back of the driver's seat or the front passenger seat, or coupled to a B-pillar of the vehicle.

7. A loudspeaker arrangement comprising:
a mid-range loudspeaker arranged in a dashboard of a vehicle;
a first tweeter arranged adjacent to the mid-range loudspeaker in the dashboard of the vehicle; and
a second tweeter arranged adjacent to the mid-range loudspeaker in the dashboard and positioned opposite to the first tweeter in the dashboard, wherein
the mid-range loudspeaker is a non-directional loudspeaker that radiates sound towards a driver's seat and towards a passenger seat in equal parts,
the first tweeter is a directional loudspeaker that radiates sound primarily towards the passenger seat, and
the second tweeter is a directional loudspeaker that radiates sound primarily towards the driver's seat,
wherein the first tweeter and the second tweeter are each arranged at a distance of no more than 10 cm from the mid-range loudspeaker,
a third tweeter and a fourth tweeter, wherein
the third tweeter is arranged distant to the mid-range loudspeaker on a first side of the mid-range loudspeaker,
the fourth tweeter is arranged distant to the mid-range loudspeaker on a second side of the mid-range loudspeaker that is opposite to the first side,
the third tweeter is a directional loudspeaker that radiates sound primarily towards the passenger seat, and
the fourth tweeter is a directional loudspeaker that radiates sound primarily towards the driver's seat, and
wherein:
the first tweeter is arranged closer to the passenger seat than to the driver's seat, and
the second tweeter is arranged closer to the driver's seat than to the passenger seat, such that a main radiation lobe of the first tweeter and a main radiation lobe of the second tweeter do not intersect.

8. The loudspeaker arrangement of claim 7 , wherein the loudspeaker arrangement is arranged centrally in the dashboard of the vehicle, such that a distance from the mid-range loudspeaker to the driver's seat equals a distance from the mid-range loudspeaker to the passenger seat.

9. The loudspeaker arrangement of claim 7 , wherein the mid-range loudspeaker has a circular cross-section, and wherein the first tweeter and the second tweeter each have a rectangular cross-section.

10. The loudspeaker arrangement of claim 7 , wherein
the third tweeter is arranged at a distance of at least 50 cm from the mid-range loudspeaker, and
the fourth tweeter is arranged at a distance of at least 50 cm from the mid-range loudspeaker.
