Haptic and sound interface

A multimodal haptic interface, comprising:

• a control circuit;
• and
• an array comprising a plurality of ultrasound transducers connected to said circuit;
• with the control circuit being configured to modulate the signals sent to the transducers in order to:
• generate, with the ultrasound waves emitted by at least some of the transducers, an acoustic pressure that is tactilely detectable on a surface of a user, in at least one first focal zone;
• and/or
• generate, with the ultrasound waves emitted by at least some of the transducers, an acoustic pressure that is audibly detectable by an auditory receiver of the user, in at least one second focal zone.
