US Patent 7252085 Device for inhalation therapy

The invention relates to a device for inhalation therapy. Said device comprises an aerosol-producing device for spraying a liquid (3), preferably comprising a membrane (1), a support unit (6), an electromechanical transducer unit (7), and a connecting device (8,9) for supplying an oscillation control signal. The inventive device also comprises a control device (10) from which an oscillation control signal can be supplied to the connecting device of the aerosol-producing device, such that the aerosol-producing device sprays the liquid. Another control signal is supplied to the aerosol-producing device (1,6,7), moving the membrane (1) in oscillation in an audible frequency range, thus causing the emission of audible signals for a user.
