The present invention provides a composite piezoelectric transducer having a piezoelectric ceramic, an organic polymer, and an electrode group formed only on surfaces of the piezoelectric ceramic. As the head section pivots from the flat orientation to an intermediate orientation, the pivot axis of the head section remains generally stationary. A closed-loop conductive winding is disposed proximate to the first conductive coil and the second conductive coil. In this configuration where the back-end modulator digitizes the error of the front-end modulator, some design constraints of the front-end are relaxed. According to the present invention, it is possible to provide a haptic feedback controller which is suitable for controlling controlled equipment in response to a pointing operation performed by a user with hisher fingertip and, at the same time, is suitable for equipment such as portable equipment deemed necessary to satisfy demand for reduction of thickness and miniaturization.
