Abstract: There is provided a loudspeaker device comprising at least one loudspeaker (L1, L2) for the playback of audio signals and at least one microphone (M1, M2) for recording ambient noises. The loudspeaker unit further has an audio input (D1) for receiving audio signals to be played back and a signal processing unit (DSP) for controlling the playback of the audio signals to be played back by the at least one loudspeaker (L1, L2) in dependence on the ambient noise recorded by the at least one microphone (M1, M2).

Abstract: There is provided a loudspeaker system having a loudspeaker unit with at least one electroacoustic transducer and a mounting holder. The mounting holder has a first end and a second end, wherein the first end can be fixed to a fixed mounting location. The second end of the mounting holder is in the form of a mounting plate in substantially perpendicular relationship to the mounting holder. The loudspeaker unit has a fixing unit. The mounting plate and the fixing unit are respectively of such a design configuration that the fixing unit can be pushed onto the mounting plate for mechanical mounting of the loudspeaker unit. The first electrical contacting means on the mounting plate and the second electrical contacting means on the fixing unit are arranged in such a way that the first and second electrical contacting means ensure an electrical contact when the fixing unit of the loudspeaker unit is pushed onto the mounting plate of the mounting holder.
