Patent number: 12208409Abstract: The invention provides a head for a fluid excitation device in which a transducer comprising a vibration generation portion and a fluid excitation portion is secured to a flexible substrate using an adhesive layer located between the vibration generation portion and the flexible substrate. An external force-applying structure is not needed to secure the vibration generation portion to the fluid excitation portion, removing a cause of significant vibration damping. Rather than damping the vibrations generated by the transducer, the flexible substrate instead itself moves in co-operation with the transducer, reducing damping effects. The design and manufacture of this arrangement is relatively simple and no complex tuning is required to ensure efficient operation over the entire operational life of the head. The head can be used in a fluid excitation device such as an atomiser or ultrasonic bath.Type: GrantFiled: November 22, 2021Date of Patent: January 28, 2025Assignee: Specialist Health Solutions LimitedInventors: Tautvydas Karitonas, Kurt Morgan
