ABSTRACT:
A piezoelectric beam is fixed at one end and is subdivided into segments, each of which is deflected by a logic one in one of the magnitude bit locations of a digital word. The total deflection of the beam is related to the total magnitude of the digital word. The segment closest to the fixed end is controlled by the most significant bit, and the segment closest to the free end is controlled by the least significant bit. The free end is connected to the cone of a speaker so that the acoustic signal resulting from the motion of the cone is related to the digital word. A buffer regulates the polarity of the voltages applied to each segment according to the sign bit in the word so that the beam deflects in either of two directions depending on the polarity of the digital word.
