  • Patent number: 11925212
    Abstract: An aerosol-generating device includes a sound generator to produce sound. The sound may be described as “high fidelity.” The sound may emulate the sound of one or more conventional uses of different smoking materials, emulate a masking noise, or include information. The sound generated may be modulated based on a user's puff. A user interface may be provided to configure the aerosol-generating device, which may include selection of the smoking material to emulate. The aerosol-generating device may store a library of sounds to use with different types of aerosol-generating substrates. The sound may be retrieved from a plurality of sounds.
