  • METHOD FOR OPERATING A SPEAKER
    Publication number: 20260067620
    Abstract: A method for operating a speaker, in particular a dynamic speaker, in which a reference signal for producing a pilot tone and a useful signal for producing sound by the speaker are processed. The reference signal is generated depending on a property of the useful signal. Advantageously, the reference signal is generated depending on an electrical property, preferably a voltage, a current, and/or a power, of the useful signal.

  • METHOD FOR OPERATING A SPEAKER
    Publication number: 20260067619
    Abstract: A method for operating a speaker, in particular a dynamic-speaker, in which a useful signal for producing sound by the speaker is linearized. According to the disclosure, the useful signal is filtered depending on frequency and only a filtered portion of the useful signal is linearized. Advantageously, the useful signal is filtered by a high-pass filter and/or a low-pass filter. In one embodiment, only a portion of the useful signal that is output by the low-pass filter is linearized.
