Device for stimulating a human erogenous zone using a variable pressure field

A device for stimulating a human erogenous zone, the device comprising:

• a housing;
• a drive device disposed in the housing, the drive device to provide a drive movement;
• a pressure chamber disposed in the housing;
• a movable wall, the drive device to cause at least a portion of the wall to repeatedly move between different wall positions to cause a volume of the pressure chamber to vary to cause pressure in the pressure chamber to modulate between positive pressures relative to an ambient pressure and negative pressures relative to the ambient pressure;
• an opening fluidly connected to the pressure chamber, the positive pressures and the negative pressures to be output via the opening;
• and
• a seal proximate to the opening, the seal to seal the pressure chamber with respect to an ambient environment,
• the drive device including a movable coil through which an electrical current is to flow and a stationary permanent magnet, the movable coil disposed in a magnetic field of the stationary permanent magnet and coupled to the wall to transmit the drive movement to cause at least the portion of the wall to move in a direction of a coil axis of the movable coil, wherein a plane perpendicular to the coil axis extends through at least a portion of the movable coil and at least a portion of the stationary permanent magnet, wherein at least a portion of the movable coil encircles the stationary permanent magnet.
