Provided herein are devices, systems, and methods configured to alleviate erectile dysfunction by more effectively preventing outwards blood flow away from the penis while more effectively allowing inward blood flow into the penis to aid in erection initiation, maintenance, and stamina. The disclosed geometry, configuration, flexibility, and pliability of the device enable its use on flaccid or erect penises. The disclosed system comprising the penile constriction device and a band enables the system to apply an adjustable compressive force on a flaccid or an erect penis.

Small high efficiency motors in order to produce large amounts of power must be operated such that they are running at high speed outside the desired vibration range for sexual stimulation. Accordingly, designs allowing for the appropriate gearing to allow heavy weights to be spun with small diameter and high efficiency whilst not increasing the outer diameter of an adult device are disclosed. Beneficial embodiments of the invention provide users with adult devices providing high impact (amplitude) vibration in a range of physical geometries compatible with providing internal and/or external stimulation which can also be offered at low cost and/or low manufacturing cost with extended operating life. Additionally, design flexibility via axial designs, non-axial designs, flexible drive designs, aperiodic drive designs, and linearly driven designs provide design solutions for implementing vibrators with low cost, high impact, targeted frequency characteristics, increased efficiency, and increased power.

Disclosed is an air suction stimulator. A suction head is formed by components, located at a suction opening, of a sleeve, and the suction head is driven by a drive component to perform suction to simulate an effect of sucking sensitive positions, such that a more gentle and pleasant suction experience is provided to improve the sexual quality.

A system and method for generating a drive signal for an electronic device provides a drive signal that causes the electronic device to be actuated in synchronization with action in a video feed. A drive signal generator predicts actions that are likely to occur next in the video feed based on an action model for the video feed and based on information about action that recently occurred in the video feed. The predicted future actions are then used to generate the drive signal that is used to actuate the electronic device.

A stimulation device is provided in accordance with one embodiment. The stimulation device includes a chamber which has a flexible wall portion. A drive unit of the stimulation device is in physical communication with the flexible wall portion so as to cause deflections of the flexible wall portion in opposing directions, thereby resulting in a changing volume of the chamber. The changing volume of the chamber results in modulated positive and negative pressures with respect to a reference pressure. An opening of the stimulation device is for applying the modulated positive and negative pressures to a body part. An appendage of the stimulation device may be used as a handle to allow a user to position the stimulation device over the body part. The stimulation device includes a control device for controlling the drive unit.

A massage device includes a shell configured to be inserted into a vagina, a lateral wall of the shell concaved inwardly and laterally relative to an outer lateral surface of the shell to define a moving space which communicates with an outside environment out of the outer lateral surface of the shell; a driving member arranged in a chamber of the shell, wherein the chamber is adjacent to and not communicating with the moving space; and a massage member connected to the driving member in a transmission way. The massage member is swingable in a lateral direction of the shell, wherein when the massage member swings, a portion of the massage member is reciprocating to at least a first position inside the moving space of the shell and at least a second position in the outside environment out of the outer lateral surface of the shell.

A massage device includes a shell, a first massage portion and a first driving unit. The shell is configured to be inserted into a human body along an insertion direction. A moving space is defined in a middle portion of the shell in the insertion direction and extends through a lateral wall of the shell to define an opening therein. The moving space communicates with an external environment out of the shell through the opening of the lateral wall of the shell. The first massage portion extends into the moving space of the shell. The first driving unit is arranged in the shell and connected to the first massage portion. Under the driving of the first driving unit, the first massage portion moves along an annular trajectory.

A massage device includes a shell configured to be inserted into the human body, a driving assembly supported by the shell, and a massage member. The shell defines a moving space therein, and the moving space communicates with an external environment out of the shell. The driving assembly includes a driving wheel and a driven wheel cooperating with the driving wheel. The massage member at least partly extends into the moving space of the shell, and is shaped as an annular belt and mounted around the driving wheel and the driven wheel. The driving wheel engages with the massage member to drive the massage member to rotate, generating a kneading stimulation effect on the human body.

A massage device includes a shell configured to be inserted into a vagina along an insertion direction and a first massage module mounted in the shell. A first massage portion is provided at a middle of the shell along the insertion direction. The first massage module includes a first motor and a swinging bar. The swinging bar is rotatably connected to the shell by a pivot extending along a lateral direction of the shell, one end of the swinging bar is connected to the first motor in a transmission way, and another end of the swinging bar extends into the first massage portion of the shell. The swinging bar is swingable about the pivot under the driving of the first motor, and the first massage portion is swingable together with the another end of the swinging bar to slap on a vaginal wall around the shell.
