Concrete vibrator-principle

The basic principle is to use the effect of the vibration caused by the motor plus eccentric copper. Use the axis of the bar-type motor (Bar Type) to extend, and use an eccentric configuration. Offset (rotating around the core of the motor) creates a feeling of concrete vibrator vibration. Because the traditional coiled motor (Cored Motor) has a large electromagnetic wave noise, it is gradually developing towards a coreless motor, and brushless motors are also beginning to be used. The quality of the motor itself determines the speed (vibration force), volume, life, and price.

Concrete vibrator-- material and appearance

A concrete vibrator is made of rubber, plastic, metal, silicon, and other materials. The surface is smooth. There are many cute shapes on the market and concrete vibrators of various colors to increase the interest of users.

Because of its small size and cuteness and easy to carry, the concrete vibrator is becoming the favorite baby of sisters. Today, Shanghai introduces the usage of the double concrete vibrator. Let's look at the picture below:

1. Standard gameplay: Place one of the concrete vibrators in the vagina, and the vibration head of the other concrete vibrator at the clitoral part, so that the double concrete vibrator can simultaneously synchronize and double stimulate the clitoris and vagina.

2. As shown above, place the double concrete vibrator on both sides of the labia, and stimulate the clitoris at the same time or with each other with two little cute vibrating heads. In actual operation, the two vibrating heads stimulate the clitoris at the same time. It can quickly reach multiple clitoris orgasms.

3. Fully penetrate the two non-vibrating heads of the concrete vibrator into the vagina and back chamber, and the vibrating heads to the outside. Why shake your head everywhere? Because there is no longer the second half of the vibrating head, so if you put it in a sensitive area, you will feel fuller.

4. The method of the back chamber is the same as the above No. 3 game. Cover the entire vulva with the vibration of the longer concrete vibrator. The vibration of the concrete vibrator can caress the sensitive area around the clitoris and labia at the same time.

5. Place the double concrete vibrator into the vagina at the same time, remember to fully penetrate it, shake the head outside, the principle is the same as the No. 3 game. The fullness produced by this gameplay is unparalleled. The double vibration can give the vagina a full range of stimulation, allowing you to quickly reach the vaginal orgasm!
