Stimulation device

A stimulation device comprising:

• a housing;
• a chamber in the housing;
• an opening to the chamber, the opening to sealingly engage a portion of a body of a user including a clitoris,
• the chamber having a first volume, a second volume, and a third volume,
• the first volume between the second volume and the third volume,
• the first volume corresponding to a pressure in the chamber being at an ambient pressure when the opening is sealingly engaged with the portion of the body, the second volume corresponding to the pressure in the chamber being at a positive pressure above the ambient pressure, and the third volume corresponding to the pressure in the chamber being at a negative pressure below the ambient pressure;
• a flexible material extending from the housing and covering at least a portion of an exterior surface of the housing;
• a drive unit in the housing, the drive unit to cause a volume of the chamber to change from the first volume to the second volume or to the third volume and then to alternate between the second volume and the third volume to cause the pressure in the chamber to modulate relative to the ambient pressure between positive pressures above the ambient pressure and negative pressures below the ambient pressure, the modulated positive pressures and negative pressures to be applied to the portion of the body via the sealing engagement of the opening;
• a microcontroller in communication with the drive unit;
• and
• a user control element supported by the housing and in communication with the microcontroller.

A stimulation device comprising:

• a housing;
• a chamber in the housing;
• an opening in communication with the chamber;
• a wall defining a portion of the chamber;
• a flexible material surrounding the opening, the flexible material to sealingly engage a portion of a body of a user including a clitoris, the flexible material covering at least a portion of an exterior surface the housing,
• at least a portion of the wall having a first position, a second position, and a third position,
• the first position between the second position and the third position,
• the first position corresponding to a pressure in the chamber being at an ambient pressure when the flexible material is sealingly engaged with the portion of the body, the second position corresponding to the pressure in the chamber being above the ambient pressure, and the third position corresponding to the pressure in the chamber being below the ambient pressure;
• a drive unit carried by the housing, the wall to sealingly separate the opening from the drive unit, the drive unit to cause the at least a portion of the wall to be displaced from the first position to the second position or to the third position and then to move between the second position and the third position to cause the pressure in the chamber to modulate relative to the ambient pressure between positive pressures above the ambient pressure and negative pressures below the ambient pressure, the modulated positive pressures and negative pressures to be applied to the portion of the body including the clitoris via the opening;
• a microcontroller operatively coupled to the drive unit;
• and
• a user control element, at least a portion of the user control element accessible via the exterior surface of the housing, the microcontroller to cause the drive unit to control a frequency of the modulated positive pressures and negative pressures in response to an input received via the user control element.

A stimulation device comprising:

• a housing;
• a wall in the housing, the wall defining a hollow space;
• an opening to the hollow space;
• a flexible material surrounding the opening, the flexible material to sealingly engage a portion of a body of a user;
• a piston in the housing and at least partially extending into the hollow space,
• the piston having a first position, a second position, and a third position,
• the first position between the second position and the third position,
• the first position corresponding to a pressure in the hollow space being at an ambient pressure when the flexible material is sealingly engaged with the portion of the body, the second position corresponding the pressure in the hollow space being at a positive pressure above the ambient pressure, and the third position corresponding to the pressure in the hollow space being at a negative pressure below the ambient pressure;
• a drive unit in the housing, the drive unit to cause the piston to move relative to the wall from the first position to the second position or to the third position and then to alternate between the second position and the third position to cause the pressure in the hollow space to modulate relative to the ambient pressure between positive pressures above the ambient pressure and negative pressures below the ambient pressure, the modulated positive pressures and negative pressures to be applied to the portion of the body via the opening;
• and
• a microcontroller operatively coupled to the drive unit.
