Abstract
The invention relates to a speaker () comprising a coil arrangement () with at least two voice coils (), a magnet system () and a membrane () being fixed to the coil arrangement () and the magnet system (). The membrane () has a first compliance (c) and together with the coil arrangement () causes a first resonance frequency (fres) for an oscillation of the membrane (). In addition, the speaker () comprises a second connector () with a second compliance (c), which interconnects the voice coils (). The second connector () together with the voice coils () causes a higher second resonance frequency (fres) for the oscillation of the membrane (). Moreover, the invention relates to an electronic sound signal circuit (), which is designed to output coil signals (SO, SO) having a frequency dependent phase shift (φ). In addition, invention relates to a sound system comprising an electronic sound signal circuit and a speaker of the above kind and to a method for manufacturing a coil arrangement ().
