Abstract
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.
