A conical pendulum consists of a weight (or bob) fixed on the end of a string or rod suspended from a pivot. Its construction is similar to an ordinary pendulum; however, instead of swinging back and forth, the bob of a conical pendulum moves at a constant speed in a circle with the string (or rod) tracing out a cone. The conical pendulum was first studied by the English scientist Robert Hooke around 1660 as a model for the orbital motion of planets. In 1673 Dutch scientist Christiaan Huygens calculated its period, using his new concept of centrifugal force in his book Horologium Oscillatorium. Later it was used as the timekeeping element in a few mechanical clocks and other clockwork timing devices.

A handheld massage device includes an actuator mechanism and a massage unit received in an outer housing. The actuator includes a motor, a bearing and a tilting piece having a first shaft coupled with the motor and a second shaft fitted into the bearing. The crank-shaped first and second shafts do not lie on a straight line. The massage unit has a base plate and massage elements mounted on the base plate. The massage elements protrude from one end of the outer housing. The bearing is fitted in the base plate. Because the first and second shafts form an angle therebetween, the base plate is tilted and swings like a conical pendulum. Therefore, the massage elements on the base plate move back and forth along a direction of an axle of the motor, thereby providing kneading and percussion massages on the user's body.
