Abstract: A sexual stimulation device has a housing and an exposed sexual organ contact surface supported by the housing. The housing defines an elongated internal cavity having a longitudinal axis extending away from the contact surface. The device also includes a mass laterally constrained within and movable linearly along the cavity, and an electrically driven actuator disposed within the housing and operable to accelerate the mass along the axis of the cavity, thereby oscillating the contact surface in a linear motion along the longitudinal axis.

Abstract: An eccentric mass (EM) motor in a vibrotactile transducer provides a wide band vibrational stimulus to a mechanical load in response to an electrical input. The eccentric mass and motor may form part of the transducer actuator moving mass, which is in contact with a load, i.e, the skin of a user. The moving mass and the actuator housing may be in simultaneous contact with the load. The moving mass may be guided by a spring between the actuator housing and the moving mass. The load, moving mass, spring compliance, and housing mass make up a moving mass resonant system. The spring compliance and system component masses may be configured to maximize the actuator displacement and/or tailor the transducer response to a desired level. This configuration may be implemented as a low-mass wearable wide-band vibrotactile transducer.

Abstract: The present invention provides a novel implementation of a low cost eccentric mass motor vibrotactile transducer providing a point-like vibrational stimulus to the body of a user in response to an electrical input. Preferably the eccentric mass and motor form part of the transducer actuator moving mass. The actuator moving mass is constrained into vertical motion by a spring between the actuator housing and moving mass. The actuator moving mass is in contact with a skin (body) load. The actuator housing is in simultaneous contact with the body load. The body load, actuator moving mass, spring compliance and housing mass make up a moving mass resonant system. The spring compliance and system component masses can be chosen to maximize the actuator displacement and/or tailor the transducer response to a desired level.

Abstract: A method and device for improving the detection of a vibrotactile stimulus. Such method may include the steps of temporarily altering the threshold of vibrational detection prior to the onset of a vibrotactile stimulus. This allows the vibrotactile system to achieve improved detection of the intended vibrotactile alert or communication stimulus without necessarily increasing the vibratory displacement amplitude of the stimulus. A corresponding enhanced vibrotactile transducer device is able to produce, over a wide frequency range, or at multiple frequencies, a vibrational stimulus against the body of a user.

Abstract: The present invention is a vibrational roller utilizing a motorized vibrational drive using a plurality of eccentric weights and associated supports. The weights are positioned along the axis of rotation in a manner to synchronize them and minimize vibrational dissipation throughout the roller. Each weight has at least one associated support. The supports then transmit vibrational forces to the surface of the roller in an evenly distributed manner. A second co-operational motor may be used to extend motor life and aid in initiating vibrations. A control panel and associated circuitry are utilized to alter vibrational characteristics. The roller may be battery powered or powered through a standard wall outlet. The roller itself is manufactured of a durable yet deformable material, such as foam rubber, and may be inserted into selectable sleeves of varying physical properties for desired effect.

Abstract: The transmission mechanism of the vibrating massager includes a stator, a movable frame supported on springy members and movably mounted around the stator, and a magnetic coil mounted around the stator and fixedly secured to the movable frame and energized to produce a magnetic force, causing the movable frame to be reciprocated relative to the stator.
