An inhaler article includes a tubular housing defining a holder body extending along a longitudinal axis from a mouthpiece end to a consumable receiving end. The holder body includes an inner tube extending along the longitudinal axis and within the tubular housing from a tube intake end to a tube exhaust end. The tube intake end is proximate the consumable receiving end. The inner tube defines an air flow lumen with two or more air flow apertures extending through a wall of the inner tube. An air blocking feature is positioned in the air flow lumen and between two of the air flow apertures. A vibration inducing element disposed on the inner tube proximate to the tube exhaust end or the tube intake end, the vibration inducing element comprises an aperture through the wall of the inner tube and having a tapered or angled downstream aperture edge.

An electronic cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An atomizer and a liquid-supply are in contact with each other. The air inlet, atomizer, and an aerosol passage are interconnected.

The disclosure provides liquid aerosol precursor compositions adapted for use in an aerosol delivery device, comprising two or more organic acids. For example, one such composition includes: at least one aerosol former, nicotine, benzoic acid, lactic acid, and levulinic acid, wherein benzoic acid is present in a molar ratio of benzoic acid to nicotine of at least 0.15, wherein lactic acid is present in a molar ratio of lactic acid to nicotine of at least 0.2, and wherein levulinic acid is present in a molar ratio of levulinic acid to nicotine of at least 0.12. The disclosure further provides devices and kits incorporating such compositions.

A device for heating a smokable material includes an elongate housing assembly having a mouth end with an opening and an opposing open component end. The housing assembly includes a hollow inner tube longitudinally extending therethrough, wherein the inner tube is in fluid communication with the opening of the mouth end and the open component end. A cartridge contains the smokable material and is disposed within the inner tube. A main node assembly includes an upper portion and a lower portion, the upper portion is insertable through the open component end into the inner tube. The lower portion of the main node assembly includes a pressure sensor configured to detect a draw on the mouth end by the user and a membrane assembly configured to generate low-frequency air vibrations in response to a signal received from the pressure sensor.

A base for an e-vaping device is configured to couple with multiple cartridges configured to generate separate, respective dispersions. The cartridges may include one or more atomizer assemblies or vaporizer assemblies. The base may include multiple connectors electrically coupled to the power supply. The connectors may be configured to couple multiple dispersion generators to a power supply of the base. The base may include control circuitry configured to independently control dispersion generation by dispersion generators coupled to the base. The control circuitry may independently control dispersion generation by the first and second cartridges based on cartridge information accessed through at least one of the first and second connectors. The control circuitry may control dispersion generation by controlling power supplied to the dispersion generators.
