Stimulation device

A stimulation device comprising:

• a housing;
• a wall defining a hollow space in the housing;
• an opening in communication with the hollow space, the opening to sealingly engage a portion of a body of a user including a clitoris;
• a piston at least partially in the hollow space, the piston movable relative to the wall, 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 opening is sealingly engaged with the portion of the body, the second position corresponding to 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;
• and
• a drive unit in the housing, the drive unit to cause the piston to move from the first position to the second position or to the third position and then to move between second position and the third position to cause a volume of the hollow space to alternate between a first volume and a second volume, the alternating volume of the hollow space to cause the pressure in the hollow space to alternate relative to the ambient pressure between positive pressures above the ambient pressure and negative pressures below the ambient pressure, the positive pressures and the negative pressures to be applied to the portion of the body via the sealing engagement of the opening.

A stimulation device comprising:

• a chamber defined by the stimulation device;
• a flexible material covering at least a portion of the stimulation device, an opening defined in the flexible material, at least a portion of the flexible material including the opening to sealingly engage a portion of a body of a user including a clitoris, the opening in communication with the chamber,
• at least a portion of the chamber 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 at least the portion of the flexible material including the opening is sealingly engaged with the portion of the body, the second position corresponding to the pressure in the chamber being at a positive pressure above the ambient pressure, and the third position corresponding to the pressure in the chamber being at a negative pressure below the ambient pressure;
• and
• a drive unit, the drive unit to cause the at least the portion of the chamber to move 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 a volume of the chamber to alternate between a first volume and a second volume, the alternating volume of the chamber to cause the pressure in the chamber to alternate relative to the ambient pressure between positive pressures above the ambient pressure and negative pressures below the ambient pressure, the positive pressures and the negative pressures to be applied to the portion of the body via the opening.

A stimulation device comprising:

• a housing;
• a chamber in the housing;
• a flexible material extending from the housing, the flexible material defining 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;
• and
• 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.
