    Abstract: The oscillation generator includes an oscillator circuit, a push-pull amplifier with inductive positive feedback connected in the circuit, a piezoceramic atomizer vibrator element, and a load-dependent regenerative feedback coupling connected to the circuit. The coupling is in the form of a tunable frequency-selective sensor having outputs connected to the inputs of the amplifier.

    Abstract: An acrosol generator core (1) has an integral body (2) and membrane (4), and a vibratory drive connected to an electrical voltage supply. In some examples the body provides the vibration drive and comprises a piezoelectric polymer (2) of P(VDF-TrFE) material. In this manner a single manufacturing operation can provide the membrane. the support. and the vibration drive. and operations such as attaching a membrane to an annular support are avoided.
