The Hitachi Magic Wand (renamed as Magic Wand Original and Original Magic Wand and referred to simply as Magic Wand) is an electrical, mains-powered vibrating massager, manufactured for relieving tension and relaxing sore muscles. 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 and is able to bring women to clitoral orgasm. The wand is long and weighs with stimulation provided by its rubberized head. Hitachi executives assisted financing the production of chocolates in the shape of the massager in 1992, in honor of the 15-year anniversary of the sex shop by and for women Good Vibrations. Subsequently the company asserted in 1999 its sole intended use was for health care purposes. Hitachi had a conflict with its U.S. distributor in 2000 and briefly stopped selling the device until it reached a new deal with distributor Vibratex. The Magic Wand sold out after being featured in a 2002 episode of ''Sex and the City''. Hitachi decided to cease production of the device in 2013 because of concerns about having the company name attached to a sex toy. Vibratex persuaded the company to continue manufacturing it under the name "Original Magic Wand", omitting the Hitachi name. In 2014, the company used the name "Magic Wand Original". Academics have researched its use for treatment of female sexual arousal disorder and chronic anorgasmiaa sexual dysfunction in which a person cannot achieve orgasm. The ''Journal of Consulting and Clinical Psychology'' published a 1979 study which found self-administered treatment and use of the Magic Wand to be the best method to achieve orgasm. In 2008, ''The Scientific World Journal'' published research finding over 93% of a group of 500 chronic anorgasmic women could reach orgasm using the Magic Wand and the Betty Dodson Method. The device was used in studies in multiple applications, including articles published in ''Dermatology Online Journal'', ''Journal of Applied Physiology'', ''Experimental Brain Research'', ''Neuroscience Letters'', and ''Journal of Perinatal & Neonatal Nursing''. The Magic Wand has alternatively been referred to as the Cadillac of vibrators,〔〔〔 the Rolls-Royce of vibrators,〔〔〔 and the mother of all vibrators.〔〔〔 Counselors Bettina Arndt, Laura Berman, Gloria Brame, and Ruth Westheimer recommended the device to women, and ''Cosmopolitan'' magazine reported the Magic Wand was the vibrator most often suggested by sex therapists. ''Mobile Magazine'' readers in 2005 voted the Magic Wand "the No. 1 greatest gadget of all time".〔 Tanya Wexler's film ''Hysteria'' featured the device while showing the evolution of the vibrator. ''Engadget'' called the Magic Wand "the most recognizable sex toy on Earth".〔 ==Design and features== The device is long and it weighs .〔〔 Muscle and nerve stimulation is provided by the device's rubberised, head, which is attached to the main body of the massager via a flexible neck. A cord is attached to the device to provide power from mains electricity with alternating current, and requires 110 Volts.〔〔 It does not take batteries. The massager provides two vibration rates5,000 and 6,000 rpm, which are equivalent to 83 Hz and 100 Hzthat are controlled by a switch on its body.〔〔〔 Specifically, research published in the journal ''Sexual and Relationship Therapy'' determined that the Magic Wand operated on its low setting at a frequency of 89 Hz and at 101 Hz on its high setting.〔 Its displacement was measured as , with an acceleration of .〔 Because the device was not originally designed as a vibrator, it exhibits some deficiencies when used for this purpose.〔 Apart from its size, bulk, and its reliance on a mains power supply that limits its portability, it is not waterproof or water-resistant, and it overheats when used for more than 25 minutes.〔 It does not work well in electrical outlets in all countries internationally. Because of the Magic Wand's popularity, various aftermarket attachments with differences in colour, pattern of studs, and material, became available to purchase.〔〔 Such attachments have been produced by multiple different companies without ties to Hitachi.〔 Without attachments, the device functions effectively as a clitoral vibrator, able to bring women to clitoral orgasm. Add-ons that are fitted over the top of the device and are used to excite the clitoris are available. An attachment called the "Wonder Wand" allows women to feel vibrations deep into the vagina.〔〔 According to an article in the ''Dermatology Online Journal'', "The Wonder Wand" is created from a plastic material which is even in consistency and may be simply cleansed after utilization.〔 Attachments made of silicone designed to aid with penetrative sensations or to modify texture of the device are available. An add-on called the "G-Spotter" fits over the device in the same fashion and turns the device into a G-spot vibrator. The "Gee-Whiz" (also referred to as "G-Whiz") is a similar type of attachment used to stimulate the G-spot.〔〔 The "Fluffer Tip Wand Attachment" may be placed over the device and can be used to mimic the sensation of cunnilingus.〔 "Liberator Axis" is a booster pillow that stabilizes the Magic Wand so the user does not have to hold it with her hands during use.〔 Attachments have been sold by Betty Dodson on her website, which provides pictorial instructions on their use with the Magic Wand.〔〔 The massager may be used without attachments for men or with the "G-Whiz" attachment; when held on the penis it can stimulate pleasurable sensations to the prostate.〔 An attachment made by an unaffiliated company provides a cap that fits over the top of the device so it can function as a male masturbation sleeve.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hitachi Magic Wand」の詳細全文を読む スポンサード リンク
