    Abstract: A vibratory penis ring mainly includes an outer and an inner ball made of a soft and elastic silicone material and having an uneven spherical outer surface, and a vibrating mechanism mounted inside the inner ball. When the vibrating mechanism is actuated, the inner ball is caused to continuously vibrate and roll inside the outer ball, so as to touch and lightly knock a user's penis through the outer ball to create a comfortable stimulating and massaging effect on the penis. The vibrating mechanism also includes light-emitting diodes to emit different color light for producing special sexual sensation.
