Abstract

Un aparato de procesamiento de audio incluye un receptor de señal para recibir una señal de contenido; un primer amplificador para emitir una primera señal amplificada de una señal de audio extraída desde la señal de contenido; un segundo amplificador para emitir una segunda señal amplificada de la señal de audio, la cual tiene una fase invertida de la primera señal amplificada; un altavoz para producir un sonido correspondiente a la señal de audio; un interruptor para ejecutar una operación de conmutación de manera que al menos una de la primera señal amplificada y la segunda señal amplificada respectivamente amplificadas por el primer amplificador y el segundo amplificador y emitidas desde los mismos pueden ser selectivamente transmitidas al altavoz; y al menos un procesador configurado para controlar la operación de conmutación del interruptor de acuerdo con un nivel de la potencia de salida del sonido.
