Stimulation device having an appendage

A stimulation device, comprising:

• a pressure field generator having a flexible wall;
• a drive unit in physical communication with the flexible wall to cause at least a portion of the flexible wall to deflect in opposing directions, thereby resulting in a changing volume of the pressure field generator, the changing volume of the pressure field generator resulting in modulated positive and negative pressures with respect to an external reference pressure;
• an opening for applying the modulated positive and negative pressures to a portion of a body of a user;
• a control device for controlling the drive unit;
• and
• a housing including an appendage configured to be inserted into an orifice of the body of the user.

A handheld stimulation device comprising:

• a housing;
• an appendage associated with the housing, the appendage defining a handle of the handheld stimulation device, the appendage configured to be inserted into an orifice of a body of a user;
• a wall disposed in the housing, the wall defining at least a portion of a chamber, and the housing including an opening to the chamber;
• a drive unit in communication with the wall, the drive unit to cause at least a portion of the wall to move to cause a volume of the chamber to alternate between a first volume, the first volume associated with positive pressures in the chamber relative to an ambient pressure, and a second volume, the second volume associated with negative pressures in the chamber relative to the ambient pressure, the positive pressures and the negative pressures to be applied to a portion of the body of the user via the opening;
• and
• a controller to control the drive unit.

A stimulation device comprising:

• a housing including an appendage configured to be inserted into an orifice of a body of a user;
• a chamber disposed in the housing, the housing defining an opening to the chamber;
• a drive unit disposed in the housing, the drive unit to cause at least a portion of the chamber to move between (a) an expanded position to cause negative pressures relative to an ambient pressure to be generated in the chamber and (b) a compressed position to cause positive pressures relative to the ambient pressure to be generated in the chamber, the positive pressures and the negative pressures to be applied to a portion of the body of the user via the opening;
• and
• a controller to actuate the drive unit.

A stimulation device comprising:

• a housing including:
• a chamber;
• and
• a wall at least partially disposed in the chamber;
• an opening to the chamber;
• an appendage configured to be inserted into an orifice of a body of a user;
• a drive unit disposed in the housing, the drive unit to apply a force to the wall to cause a volume of the chamber to alternate between a first volume and a second volume, pressure in the chamber to modulate between positive pressures relative to an ambient pressure and negative pressures relative to the ambient pressure in response to the alternating volume of the chamber, the positive pressures and the negative pressures to be applied to a portion of the body of the user via the opening;
• and
• a controller to actuate the drive unit.
