The liquid spray-head comprises: a housing to be secured to a container containing a sprayable liquid; a liquid ejecting member connected to said housing, to be contacted with a liquid providing member for providing liquid to said liquid ejecting member; and a vibrating actuator connected to said liquid ejecting member for actuating said liquid ejecting member so as to generate a spray of liquid. The spray-head comprises a flexible member extending from an outer perimeter of said liquid ejecting member to an inner wall of the housing for providing a flexible connection between said housing and said liquid ejecting member, the flexible member being arranged so as to provide a stable working contact between said liquid ejecting member and said liquid providing member.
