A study of efficient speaklet driving mechanisms for use in a digital loudspeaker array based on PZT actuators


The concept of a Digital Loudspeaker Array (DLA) requires a driving signal for a speaklet (tiny loudspeaker) with a short rectangle pulse. The speaklet takes the form of a diaphragm, which vibrates freely and emits acoustic energy at its resonant frequency. This study gives a guideline for the design of PZT speaklets for assigning the required resonant… (More)
