Wand Vibrator
A wand vibrator is a massaging device which is often also used as a vibrator and a sex toy. It consists of a rounded vibrating ball attached to a handle. The vibration is provided by an electric motor in the handle that rotates an unbalanced flywheel mounted either within the vibrating ball connected to the motor via a flexible coupling, or, less effectively, within the handle itself attached directly to the motor shaft. The Hitachi Magic Wand, available since 1968, is the best-known wand vibrator brand, but many other similar devices exist, including the Doxy wand vibrator made in Britain. Operation Wand vibrators can be powered either by batteries or from mains power, with the most powerful devices being typically mains-powered. Many recently designed mains-powered wand vibrators use a plug-in AC adaptor power supply which converts mains voltages down to safer voltage levels. In addition to use in masturbation, wand vibrators may also be used in orgasm control play, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vibrator (sex Toy)
A vibrator, sometimes described as a massager, is a sex toy that is used on the body to produce pleasurable sexual stimulation. There are many different shapes and models of vibrators. Most modern vibrators contain an electric-powered device which pulsates or throbs. Vibrators can be used for both solo play and partnered play by one or more people. Devices exist to be used by couples to stimulate the genitals of both partners. They can be applied to erogenous zones, such as the clitoris, the vulva or vagina, penis, scrotum or anus, for sexual stimulation, for the release of sexual frustration and to achieve orgasm. Vibrators may be recommended by sex therapists for women who have difficulty reaching orgasm through masturbation or intercourse. Types Vibrators very often generate their vibrations using eccentric weights driven by a conventional electric motor, but some use electromagnet coils. Some vibrators are marketed as "body massagers"—although they still may be used, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sex Toy
A sex toy is an object or device that is primarily used to facilitate human sexual pleasure, such as a dildo, artificial vagina or vibrator. Many popular sex toys are designed to resemble human genitals, and may be vibrating or non-vibrating. The term ''sex toy'' can also include BDSM apparatus and sex furniture such as slings; however, it is not applied to items such as birth control, pornography, or condoms. Alternative terms for ''sex toy'' include adult toy and the dated euphemism marital aid. ''Marital aid'' also has a broader meaning and is applied to drugs and herbs marketed to enhance or prolong sex. Sex toys are most commonly sold at sex shops or online, but they may also be sold in a pharmacy or chemist store, a pornographic store, a head shop, or a department store. Sex toys are available in almost all countries for males and females. Types Erotic electrostimulation Another form of sex toys for both men and women are those for erotic electrostimulation. Ero ...

Electric Motor
An electric motor is an Electric machine, electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a Electromagnetic coil, wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, Inverter (electrical), inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be Brushed motor, brushed or Brushless motor, brushless, single-phase, Two-phase electric power, two-p ...

Flywheel
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity ...

Flexible Coupling
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiter, torque-limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and maintenance of couplings can lead to reduced maintenance time and maintenance cost. Uses Shaft couplings are used in machinery for several purposes. A primary function is to transfer power from one end to another end (ex: motor transfer power to pump through coupling). Other common uses: * To alter the vibration characteristics of rotating units * To connect the driving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hitachi Magic Wand
The Hitachi Magic Wand (renamed Magic Wand Original and Original Magic Wand) is an AC-powered wand vibrator. It was originally manufactured for relieving tension and relaxing sore muscles, however, it is most known for its use as a sex toy. Japanese company Hitachi listed the device for business in the United States in 1968. Sex educator Betty Dodson popularized its use as a vibrator and masturbation aid for women during the sex-positive movement in the late 1960s. It functions effectively as a clitoral vibrator, to bring women to orgasm. The wand is long and weighs with stimulation provided by its rubberized head. Hitachi asserts that its sole intended use is for health care purposes. Hitachi's national sales manager said "we approach the massagers as personal care items... the people we hire know what it's for without our having to say it". Hitachi had a conflict with its U.S. distributor in 2000 and briefly stopped selling the device, until it reached a new deal with distr ...

AC Adaptor
An AC adapter or AC/DC adapter is a type of external power supply, often enclosed in a case similar to an AC plug. Other common names include wall wart, power brick, wall charger, and power adapter. Adapters for battery-powered equipment may be described as chargers or rechargers (see also battery charger). AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power from mains power. The internal circuitry of an external power supply is very similar to the design that would be used for a built-in or internal supply. External power supplies are used both with equipment with no other source of power and with battery-powered equipment, where the supply, when plugged in, can sometimes charge the battery in addition to powering the equipment. Use of an external power supply allows portability of equipment powered either by mains or battery without the added bulk of internal power components, and ...

Masturbation
Masturbation is the sexual stimulation of one's own genitals for sexual arousal or other sexual pleasure, usually to the point of orgasm. The stimulation may involve hands, fingers, everyday objects, sex toys such as vibrators, or combinations of these. Mutual masturbation is masturbation with a sexual partner, and may include manual stimulation of a partner's genitals ( fingering or a handjob), or be used as a form of non-penetrative sex. Masturbation is frequent in both sexes and at any age. Various medical and psychological benefits have been attributed to a healthy attitude toward sexual activity in general and to masturbation in particular. No causal relationship is known between masturbation and any form of mental or physical disorder. In the Western world, masturbation in private or with a partner is generally considered a normal and healthy part of sexual enjoyment. Masturbation has been depicted in art since prehistoric times, and is both mentioned and discussed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edging (orgasm)
Edging, peaking, or surfing''Extended Massive Orgasm'', Steve and Vera Bodansky, (2000), pp. 91, 92, 94–98, . is a sexual technique whereby an orgasm is controlled. It is practiced alone or with a partner and involves the maintenance of a high level of sexual arousal for an extended period without reaching climax. When practiced by males, direct sexual stimulation without the refractory period after orgasm is observed. When the controlled orgasm is achieved, the physical sensations are greater as compared to conventional orgasm. Orgasm control is referenced as "slow masturbation" in Alex Comfort's ''The New Joy of Sex'' (1993) and "extended massive orgasm" in Vera and Steve Bodansky's 2000 book of the same name. It is similar to the Venus Butterfly technique used in the volume ''The One Hour Orgasm'' (1988) by Leah and Bob Schwartz. Detailed practices including exercises can be found in several books, such as Mantak Chia's ''The Multi-Orgasmic Man''. Orgasm control involves e ...

Forced Orgasm
A forced orgasm is consensual BDSM or kinky sexual play whereby a person consents to be forced to orgasm in a way that is beyond their control. The person being brought to involuntary orgasm would typically be put in physical restraints to deprive them of the ability to control the onset and intensity of orgasm, and to increase the feeling of helplessness, a situation which some people find sexually arousing. The practice of forced orgasm may also be combined with other orgasm control plays, such as orgasm denial, edging, or ruined orgasms. With the consenting partner restrained and unable to stop being sexually stimulated, the active partner would stimulate their genitals and other erogenous zones until the bound partner is brought to orgasm, and sometimes beyond. The bound partner is open to a wide range of sexual stimulation, including vaginal, oral, or anal sex. Forced orgasms may be induced with manual stimulation of the genitals (in the form of a handjob or fingeri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
