Vibrator structure, and cartridge and aerosol generating device including the same

A cartridge comprising:

• a liquid storage unit;
• a wick for absorbing an aerosol generating material stored in the liquid storage unit;
• and
• a vibrator structure comprising:
• a vibrator configured to vibrate according to an electrical energy applied to the vibrator, the vibrator comprising a first surface and a second surface opposite to the first surface;
• a first electrode arranged on at least one region of the first surface;
• a second electrode arranged on at least one region of the second surface;
• a metal body having an outer surface and an inner surface, the inner surface of the metal body surrounding the vibrator and being in contact with at least one region of the first electrode;
• a first elastic body coupled to the outer surface of the metal body to receive a vibration of the vibrator and absorb the vibration, the first elastic body including a hole portion exposing at least a portion of a surface of the vibrator;
• a support supporting the metal body, the support comprising a conductive portion and an insulator;
• a lower electrode in contact with the second electrode;
• and
• a pressing body in contact with at least a portion of the vibrator and the lower electrode, wherein
• the metal body comprises a side wall forming a hollow for accommodating the vibrator,
• the conductive portion of the support is electrically connected to the metal body at one end of the sidewall of the metal body, and
• the electrical energy applied from an external power source is transferred to the first electrode through the metal body, and the vibrator structure atomizes the aerosol generating material supplied to the vibrator through the wick.
