Abstract

See full text

Electroacoustic device (5) comprising: —an ultrasonic wave transducer (15) comprising a piezoelectric substrate (10) and first (30) and second (35) electrodes in contact with the piezoelectric substrate, and —a carrier (10), the transducer being attached to the carrier and acoustically coupled to the carrier, and the first and second electrodes being sandwiched, at least partly, between the piezoelectric substrate and the carrier, the device being configured to generate an ultrasonic surface wave (W) propagating through the carrier at a distance from the transducer when an electric current passes through the first and second electrodes.
