Electroacoustic device

摘要

Electroacoustic device 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 support (10) , the transducer being attached to the holder and acoustically coupled with the holder, and the first and second electrodes being sandwiched, at least in part, between the piezoelectric substrate and the holder, the device being configured to generate an ultrasonic surface wave (W) propagating in the remote transducer mount, when an electric current flows through the first and second electrodes.
