    Abstract: The transducer comprises for example a block (1) of sensitive elements such as piled piezoelectric disks held up by a stud bolt between two ferrules and a shell (8) all in one piece, that is arranged around the piling with a concave central part (8A) extended on either side by a solid cylindrical part (8 B, 8 C). Two sleeves are arranged at the two opposite ends of the transducer and elastic elements (14) for decoupling them in relation to the vibrating block (1) are interposed. A flexible housing (18) can be placed around the shell (8) so as to insulate from the outside environment the inner volume of the transducer that can be filled with a fluid such as oil. Connecting means allow the vibrating block to be connected to an exciting voltage source. The transducer can be used for the emission of vibrations at sea or in wells and notably petroleum or gas wells for example.

    Abstract: A spray head for spraying a cosmetic or dermatological composition, in particular for application to the human body, may include a sonotrode for transmitting ultrasound vibration from a transducer to an ejection surface for ejecting particles of composition, the sonotrode including a channel for feeding the composition to the ejection surface. The channel may present a narrow portion between a composition inlet into the sonotrode and the composition outlet to the ejection surface.
