The second electronic circuit system is configured to output a second electronic signal associated with the first electronic signal.

An apparatus includes a simulated medicament delivery device and an electronic circuit system. The simulated medicament delivery device includes a housing, and is devoid of a medicament delivery mechanism that causes a medicament to be delivered. The electronic circuit system is coupled to the housing and includes an audible output device and a cover. The housing of the medicament delivery device and the cover of the electronic circuit system collectively define an acoustic enclosure. The audible output device is configured to be disposed within the acoustic enclosure.

Some embodiments of the invention relate to an inhaler device for pulmonary delivery of at least one substance from a drug dose cartridge to an inhaling user, comprising: a first conduit for conducting a carrier airflow to a proximal opening of a mouthpiece for use by the user; a holder configured to position the dose cartridge within the carrier airflow; and a second conduit for conducting a shunting airflow to the mouthpiece without passing through the dose cartridge position. In some embodiments, a controller connected to a valve controls a rate of carrier airflow, for example by controlling the shunting airflow, based on a sensor indication of airflow rate and a target airflow profile.

A method and a circuit system for driving a nebulizer are provided. When the nebulizer receives acoustic waves, a control circuit extracts audio signals from the acoustic waves. Afterwards, the control circuit determines if the audio signals are within a predetermined frequency range, and can determine whether or not to drive a circuit to produce an aerosol based on the audio signals. Further, a volume of the acoustic waves can also be used to determine whether or not to produce the aerosol, and also determine an output rate of the aerosol. The circuit system of the nebulizer includes an audio receiver for receiving the acoustic waves, an aerosol generator for producing the aerosol, and the control circuit used to control a driving circuit of the aerosol generator to drive a vibrational element to produce the aerosol through vibration in response to the audio signals and the volume.
