摘要:
A device (20) for controlling an audio signal comprising at least: means for commanding, rotationally mobile around an axis of rotation (A) relatively to a footing, first means for detecting a movement in rotation of the commanding means, capable of delivering a first signal, second means for detecting a movement in translation along an axis (z) substantially parallel to the said axis of rotation (A), capable of delivering a second signal. According to the invention, the said second means for detecting comprise at least one pressure sensor (210) delivering said second signal and comprising at least a upper part (210A), a lower part (210C), and a central part (210B) located between the upper part and the lower part, at least one of these parts being rigid, and at least one of these parts being elastic and deformable along an axis substantially parallel to the said axis of rotation (A).
摘要:
The invention relates to a device for controlling a material, the device including at least one transmitter for transmitting an electromagnetic signal at a carrier frequency Fp to illuminate the material and one receiver for receiving the electromagnetic signal, wherein the device further includes a first modulator for modulating the electromagnetic signal at a frequency Fm1, the first modulator being arranged, on the signal path, between the transmitter and the material in order to spatially sample the emitted electromagnetic signal; second modulator for modulating the electromagnetic signal at a frequency Fm2, the second modulator being arranged, on the signal path, between the material and the electromagnetic signal receiver in order to spatially sample the electromagnetic signal passed through the material.
