Abstract:
    The invention relates to a dielectric resonator oscillator, comprising a dielectric resonator (4) which is contained in a resonant cavity (2) for generating a signal that oscillates at a predetermined central frequency. The dimensions of the resonator and the conditions at the boundaries of the cavity determine the resonance frequency of the resonator. The invention also comprises means (17, 18, 19) for modifying the distribution of the electromagnetic fields in the cavity according to acoustic pressure waves, said means being sensitive to said acoustic pressure waves. The invention also relates to a voice control device which is provided with an inventive oscillator. The invention is concretely suitable for remote voice control devices for controlling household equipment.
