Patent ID: 7477752

Claim:
Loudspeaker system with three loudspeakers, comprising: a first and a second amplifier, each of which amplifies one channel of an audio signal, wherein outputs of the amplifiers are in phase opposition, the outputs of the amplifiers being connected to inputs of the first and second loudspeakers, respectively, wherein the outputs of the amplifiers are also connected to the inputs of the third loudspeaker; said amplifiers being configured as bridge output stages (BF, BR); a device for partitioning the audio signal into at least two parallel channels is connected to inputs of both bridge output stages, wherein an inverter is provided between the output of a first part of the device for a first channel and, in each case, one of the inputs of the bridge output stages, wherein summators are connected in front of each of the inputs to the bridge output stages, and the output of a second part of the device for a second channel is connected to inputs of the summators, wherein for one bridge output stage, a further inverter is provided between the output of the second device of the second channel and inputs of the summators for the one bridge output stage, and wherein the third loudspeaker is connected to two opposite-phase outputs of the two bridge output stages.
