  • Piezoelectric Resonator with the Water as Acoustic Path

    Created by LTsim84, published on 20-11-2012

    piezoelectric transducer (PZT-5A material) with acoustic path that consists of the transducer body X1 with thickness L=0.5m and two infinite water layers X2,X3 with cross-sectional area of 1cm2 (S=1e-4m2) for all layers. V=1500m/s is sound speed and d=1000kg/m3 is the density.

  • Piezoelectric Resonator with the Air round-up

    Created by LTsim84, published on 16-11-2012

    this circuit uses a model of the acoustic medium adapted to an electric transmission line. In analogy to the equivalent circuit of a transmission line, the model proposed represents the piezoelectric thickness vibrator by lumped elements, i.e., capacitor, inductor, and current-controlled current source. In order to unify electric and acoustic theory, an impedance type analogy is chosen where mechanical force is represented by voltage and particle velocity is represented by current. This configuration implements a Resonator with the Air round-up.

  • Electro-acoustic Echo System of an Ultrasonic Piezoelectric Transducer

    Created by LTsim84, published on 14-11-2012

    The project consists of a pulse generator and diode limiters and an acoustic path with the piezoelectric transducer (PZT-5A material). The acoustic path consist of two infinite iron layers X2, X4; transducer body X1, with thickness L=0.5mm; and water layer X3 L=10mm. All acoustic elements cross-sectional area is 1cm2 (S=1e-4m2). The V parameter under X2, X3, X4 is sound speed and d is density (Water: V=1500m/s, d=1000kg/m3; Iron: V=5170m/s, d=7900kg/m3). This model allows the simultaneous evaluation of the electric and acoustic characteristics of a complex piezoelectric system with an acoustic load. This model is very useful for the investigation of the acoustic and electric coupling. It also helps to optimize the transducer’s power amplifier for best acoustic effectiveness.

  • SPICE Simulation of a Crystal Oscillator

    Created by LTspiceDesigner, published on 25-10-2012

    This circuit models the crystal with the low impedance series resonance and the high impedance resonance, through parameters Rs, Ls, Cs and Cp. the series frequency resonance is fs = 1/(6.28*SQRT(Ls*Cs)), and the parallel frequency resonance is fp= fs*SQRT(1+Cs/Cp)
