Dielectric resonator oscillator and voice control device

摘要

The invention relates to a dielectric resonator oscillator, comprising a dielectric resonator (4) contained in a resonant cavity (2) in order to generate a signal oscillating at a predetermined central frequency, the dimensions of the resonator and the limiting conditions in the cavity being capable of determining the resonant frequency of the resonator. It comprises means (17, 18, 19) sensitive to acoustic pressure waves capable of modifying the distribution of the electromagnetic fields in the cavity as a function of said acoustic pressure waves. The invention also relates to a voice control device equipped with an oscillator according to the invention. Particular application to remote voice control devices for controlling domestic equipment.
