1. A sexual stimulation device comprising:
a housing;
a drive unit at least partially disposed within the housing; and
a first stimulator directly or indirectly coupled with the drive unit and driven by the drive unit to generate a reciprocating motion, the reciprocating motion being configured to stimulate a sensitive area of a human body,
wherein:
the first stimulator is coupled to a motor of the drive unit via a mechanical linkage,
a stroke of the mechanical linkage has a stroke length within a range of 0 mm to 15 mm,
the first stimulator is driven at a frequency of impact of less than 3000 times per minute,
the motor has an output shaft coupled with a gear having a slide,
the mechanical linkage comprises a connecting rod having a slot,
the slide is disposed within the slot such that, as the slide traces its circle, the connecting rod moves up and down in a reciprocating fashion, and
the connecting rod is restricted from lateral motion by a guide such that the connecting rod moves in a reciprocating fashion as a result of movement of the motor.
