We proposed different states of piezoelectric transducer's mounting on DJ and examined the results to determine the optimum state for maximization of the converted power. We proposed a technique which comprises four stages, and each stage is composed of a piezoelectric transducer followed by a voltage multiplier. The outputs of the four stages were connected in parallel, and these transducers were mounted via their bodies on the slim diaphragm of the acoustic focusing tube. The results indicated that the maximum converted power values were 1.225 mW with a load resistor of 10 k for one stage, 1.089 mW with a load resistor of 10 k for two stages, 1.682 mW with a load resistor of 5 k for three stages, and 5.891mW with a load resistor of 2.2 k for four stages at a sound intensity level of 85 dB and sound wave frequency of 2.1 kHz.en-USUniversity for Acoustic energy scavengingpower extractionpiezoelectric arrayload resistordisk jockeyArticlehttps://doi.org/10.1080/00207217.2018.144042
