  • Device and method for filtering the resonance peak in a circuit for supplying at least one loud speaker upstream of the latter
    Patent number: 10271139
    Abstract: The present invention relates to an acoustic signal supply circuit of at least one loudspeaker (HP), this circuit comprising a filtering device of the resonance peak occurring at a given frequency of the supply current, characterized in that the filtering device of the peak is incorporated in a first branch bypassing the intermediate circuit between at least two converters (A, A0), this filtering device being purely electrical in the form of an impedance (Z3) connected, on the one hand, at a point on the intermediate circuit and, on the other hand, to a ground instrumentation, the impedance being called RLC (Z3) for comprising at least one first resistor (R3), at least one first capacitor (C3) and at least one first inductor (L3) arranged in series, the parameters of the first resistor (R3), the first capacitor (C3) and the first inductor (L3) being predetermined as a function of the resonance peak to be filtered.
    Type: Grant

  • Device and method for filtering the resonance peak in a power supply circuit of at least one loudspeaker
    Patent number: 10212515
    Abstract: The present invention relates to an acoustic signal supply circuit of at least one loudspeaker (HP) incorporating a filtering device of the resonance peak of said at least one loudspeaker (HP) occurring at a given frequency, characterized in that the filtering device of the resonance peak of said at least one loudspeaker (HP) is incorporated either into the first instrumentation ground circuit or in the feedback loop, this filtering device being purely electrical in the form an impedance incorporated in the first instrumentation ground circuit or in the feedback loop, the impedance parameters being predetermined as a function of the resonance peak to be filtered of said at least one loudspeaker (HP).
