i tried that no voltage

I am doing a project on piezoelectricty and i need to know where to get piezo disks that will have this effect i live in Canada and fast shipping is preffered

thank you very much I will try with green LED I will also try using more than one disk at a time. just wondering i sodor the WIRES to to metal disk and the smaller part of the crystal disk that is seprsted from the rest

My disks are 3.7 cm in diameter what type of led should i use. by the way thanks for the help

how do i wire this disk with the detectors

how would you find a combo like that

so how do all the videos on youtube of someone poking a disk and the led soldered to it lighting up work?

I hae aqiured a piezo disk and LEDS but it will not power them. i do not know if it is the disk or an led. I tried the LED with AA AAA and D batteries but only turned on with 9V they are sea green

can small piezoelectric disks 3.7x3.7 cm inside a tube with a buzzer at the other end be able to power an LED

thank you so much for you help i may change the idea of a low frequency, here is the model of sound generator i have it was supposedly good for piezoelectricty HT2844 4-Sound Generator and thanks again for the help

I am in the process of building a piezoelectric device to harvest sound with a frequency generator at one side of a plastic/glass tube which sends out a low frequency which is then picked up by a piezo disk which send the energy to an led which demonstrates hoe sound can be converted to...
