An article in the shape of a circle (so-called ‘coin vibration motor’) with a diameter of 9 mm and a thickness of 4 mm with an inbuilt 4 V DC, 1 W electrical motor. The article is designed to be used in tablets, mobile phones etc. to create a vibration effect. That effect is the result of the rotation of the shaft of the motor due to the presence of a non-symmetric mass attached to the shaft. For mounting purposes the article is provided with self-adhesive tape on one side.
