Abstract

A column loudspeaker system is provided. The column loudspeaker system includes a subwoofer base and a loudspeaker column arrangement. The loudspeaker column arrangement includes a loudspeaker region with at least one loudspeaker and an extension region disposed between the subwoofer base and the loudspeaker region and is electrically and mechanically connected thereto. The at least one rechargeable battery is provided in the loudspeaker column or subwoofer base.

Claims

1. An active column loudspeaker system, comprising:

a subwoofer base;

a loudspeaker column arrangement that includes a loudspeaker region with at least one loudspeaker; and

an extension region disposed between the subwoofer base and the loudspeaker region and is electrically and mechanically connected thereto,

wherein at least one rechargeable battery is provided in the loudspeaker column or subwoofer base.

2. The system of claim 1, wherein the loudspeaker region is designed as a loudspeaker column having a separate component and

wherein the extension region includes one or a plurality of extension columns forming separate components,

wherein the loudspeaker column and the extension column is electrically and mechanically connected to one another, and that the battery is disposed in the extension column adjoining the subwoofer base.

3. The system of claim 1 further comprising a charging station integrated into the subwoofer base

4. The system of claim 1 wherein the extension column included with the battery is connected to an external charging station.

5. The system of claim 1, further comprising a display device configured to display the charge state (L1-L4) of the battery that is disposed on the extension column.

6. The system of claim 5, wherein the display device is designed as a bar display.

7. The system of claim 1, further comprising a warning device configured to emit an acoustic or visual warning signal at a predetermined time prior to complete battery discharge.

8. The system of claim 1 wherein the subwoofer base includes an integrated mixing desk.

9. The system of claim 1 wherein, at least one additional extension column having a rechargeable battery is provided as a replacement part.

10. The system of claim 1, further comprising a plug connection provided as an electromechanical connection device.

11. An active column loudspeaker system, comprising:

a subwoofer base;

a loudspeaker column arrangement;

having a loudspeaker region with a loudspeaker, and an extension region disposed between the subwoofer base and the loudspeaker region and is electrically and mechanically connected thereto,

wherein an adapter is electrically and mechanically connected to the loudspeaker column arrangement or to the loudspeaker region, and via the loudspeaker column arrangement or wherein the loudspeaker region is connected to the subwoofer base or another external separate signal source using a signal line

12. The system of claim 11, characterised by at least one characterising part of claim 2.
