Embodiments provide a compensator for a loudspeaker system having a first loudspeaker group having at least one sound transducer, the first loudspeaker group being configured to generate a first sound signal based on an audio signal, the sound signal having a useful signal portion and a distortion signal portion. The compensator has a second loudspeaker group having at least one sound transducer, the second loudspeaker group being configured to generate a second sound signal based on a compensation signal, the second sound signal compensating and/or reducing the distortion signal portion when superimposed with the first sound signal.

Compensation means for a loudspeaker system and loudspeaker system

An array of electroacoustic actuators includes at least five electroacoustic actuators, wherein the electroacoustic actuators are connected such that, in a first parallel branch, at least two electroacoustic actuators are connected in series and, in a second parallel branch, an electroacoustic actuator is connected in series to a parallel connection of two electroacoustic actuators, the first parallel branch being connected in parallel to the second parallel branch, and the parallel branches connected in parallel being configured to be driven by an actuator amplifier, or wherein the electroacoustic actuators are connected such that, in a first serial branch, at least two electroacoustic actuators are connected in parallel and, in a second serial branch, an electroacoustic actuator is connected in parallel to a serial connection of two electroacoustic actuators, the first serial branch being connected in series to the second serial branch, and the parallel branches connected in series being configured to be driven by an actuator amplifier.

Array of electroacoustic actuators and method for producing an array

A loudspeaker array includes an encapsulated baffle and a multitude of sound transducers. The encapsulated baffle includes a multitude of recesses arranged next to each other on a first main surface. The sound transducers of the multitude of sound transducers are arranged in the associated recesses such that an encapsulated rear volume is formed by each recess for the respective sound transducer.

Loudspeaker array

An electroacoustic driver includes a diaphragm, a diaphragm drive system and a diaphragm suspension. The diaphragm system is configured to subject the diaphragm to a motion, wherein the diaphragm suspension is configured to guide the diaphragm. The diaphragm drive system includes an active element configured to actively influence the motion of the diaphragm.
