Abstract
Volatile liquid droplet dispenser device, comprising: a first substrate having a space for containing liquid, and liquid outlet means for ejecting liquid from the device, the space arranged proximate to the liquid outlet means so liquid may exit the space by traversing the liquid outlet means, a second substrate comprising a support for receiving and holding the first substrate, and a vibrating element arranged to actuate liquid in the space so liquid undergoes vibration and contacts the liquid outlet means thereby exiting the device as a liquid droplet spray, wherein the liquid outlet means comprises a perforated nozzle membrane having a plurality of outlet nozzles, and an actuating element arranged between the vibrating element and the first substrate, and a sealing element arranged between the actuating element and the first substrate, wherein the actuating element and the sealing element are arranged to transmit ultrasound energy to liquid in the space.
