Loudspeaker with dynamically controlled pairs of voice coil sections

A voice coil driving system of a loudspeaker comprising:

• a magnetic circuit having an air gap;
• a voice coil suspended in said air gap, said voice coil comprising a plurality of voice coil sections, said plurality of voice coil sections comprising a main voice coil section, and a pair of auxiliary voice coil sections arranged along a travelling axis with voice coil sections of said pair of auxiliary voice coil sections arranged respectively on either side of said main voice coil section;
• and
• a voice coil controller arranged to cause application of an audio signal to said voice coil suspended in the air gap to produce an electromotive force configured to move said voice coil along said travelling axis, wherein said applying an audio signal comprises continuously coupling a main driving signal based on said audio signal to said main voice coil section and selectively coupling an auxiliary driving signal based on said audio signal to said pair of auxiliary voice coil sections,
• wherein said main driving signal and said auxiliary driving signal are configured to cause current to flow in a same azimuthal direction around said travelling axis of said voice coil.
