摘要：

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.
