1. for generation of a sound system for sound, sound system comprises:

  • Processing unit, for the treatment of input audio signal to produce loudspeaker signal;

    Loud speaker, produces sound for depending on loudspeaker signal, and loud speaker comprises that the temperature of voice loop depends on loudspeaker signal for driving the voice loop of loud speaker;

    AndMonitor, for monitoring voice loop for the electroresponse of loudspeaker signal, processing unit is configured for change loudspeaker signal, the temperature of voice loop is controlled in the response of being monitored to depend on, and changes loudspeaker signal and comprises at least one signal component in loudspeaker signal is decayed to control the temperature of voice loop;

    Wherein, processing unit comprises;

    For generation of the signal generator of estimated signal, to process input audio signal and be configured for estimated signal and input audio signal are combined to produce the processing unit of loudspeaker signal, estimated signal comprises the signal with specific estimated frequency, andFrequency filter, for removing the signal component of estimated frequency before the input audio signal of filtering and estimated signal are combined from input audio signal.
