Abstract[English]
Disclosed herein is a method comprising: sending M alternating currents respectively through M electrical conductors of a transducer while the M electrical conductors are in a magnetic field, resulting in M alternating Lorentz forces being applied to the M electrical conductors respectively, resulting in first vibrations of the M electrical conductors respectively. The M alternating currents have respectively M frequencies each of which is at least 20 kHz, and M is a positive integer.[French]
L'invention concerne un procédé comprenant : l'envoi de M courants alternatifs respectivement à travers M conducteurs électriques d'un transducteur tandis que les M conducteurs électriques sont dans un champ magnétique, ce qui conduit à l'application de M forces de Lorentz alternées aux M conducteurs électriques respectivement, entraînant des premières vibrations des M conducteurs électriques, respectivement. Les M courants alternatifs ont respectivement M fréquences dont chacune est d'au moins 20 kHz, et M est un nombre entier positif.
