description A snowboard or ski includes an active piezoelectric damper system. The damper system includes a sensor for sensing the frequency of vibration of a portion of the ski or snowboard body. The damper system also includes a power supply, a control circuit and a piezoelectric damper (14). The control circuit generates a control signal that is an inverse of the electrical signal produced by the sensor, and that is further proportional to the amplitude and to the frequency of the sensed electrical signal. The control signal is supplied to a piezoelectric damper (14), also mounted within the snowboard or ski, which deforms or stiffens in an alternating cyclic fashion to reduce or cancel out the vibrational frequency.
