A loudspeaker (1) having a conductive suspension section (3) and two electrodes (5, 6) is controlled by generating a measuring current in the conductive suspension section (3), detecting the voltage thus generated, and using the voltage to control the output power to the loudspeaker. The control method and device may be used for loudspeaker protection, motional feedback and limiting the output power. The conductive suspension section (3) may be part of the rim of the loudspeaker and may be made of conductive rubber. |
