Green speaker design is a new concept for developing active loudspeaker systems that generate the required sound output with minimum size, weight, cost, and energy. This paper focuses on the optimization of the transducer by exploiting the new opportunities provided by digital signal processing. Nonlinear adaptive control can compensate for the undesired signal distortion, protect the transducer against overload, stabilize the voice coil position, and cope with time varying properties of the suspension. The transducer has to provide maximum efficiency of the electroacoustical conversion and sufficient voltage sensitivity to cope with the amplifier limitations. The potential of the new concept is illustrated on a transducer intended for automotive application.
