Abstract: The invention has for object a device for controlling (2) at least one audio or video signal comprising: means for controlling mounted mobile in rotation about an axis of rotation (z) on a base, first means of detecting a displacement in rotation of the means for controlling able to generate a first signal, said first signal supplying means for processing said at least one audio or video signal, with the first means of detecting comprising means for measuring the angle of rotation of the means for controlling, means for displaying and/or light-emitting means, comprising several sources of light forming at least first and second means of graduation. According to the invention, said sources of light of said first and second means of graduation are selectively controlled by said means for processing according to the measurement of the angle of the rotation of said means for controlling.

Abstract: 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).
