1. An ultrasonic head comprising several ultrasonic devices, characterized in that each of said ultrasonic devices comprises an ultrasonic transducer and a supplying device to individually supply power to the ultrasonic transducer of said ultrasonic device,
for each of said ultrasonic devices, the supplying device comprises a power interface configured to receive a drive signal, and to provide an analog power signal to said ultrasonic transducer so as to produce an ultrasonic wave of a setpoint frequency,
for each of said ultrasonic devices, the supplying device comprises a tuning circuit that is mounted between the power interface and the ultrasonic transducer of said ultrasonic device, which tuning circuit is controlled by a tuning control circuit, wherein the assembly formed by the transducer and said tuning circuit has a determined resonant frequency.
