When a voltage is applied to these crystals, they push on one conductor and pull on the other. The result of this push and pull is a sound wave. These buzzers can be used for many things, like signaling when a period of time is up or making a sound when a particular button has been pushed. The process can also be reversed to use as a guitar pickup. When a sound wave is passed, they create an electric signal that is passed on to an audio amplifier. 0-20mm http://www.buzzer-supplier.com/product_category/0-20mm_1528.html 0-20mm 21mm--29mm http://www.buzzer-supplier.com/product_category/21mm--29mm_1529.html 30mm--39mm http://www.buzzer-supplier.com/product_category/30mm--39mm_1530.html 40mm--49mm http://www.buzzer-supplier.com/product_category/40mm--49mm_1531.html ≥50mm http://www.buzzer-supplier.com/product_category/≥50mm_1532.html Magnetic Buzzer(Self-Drive) http://www.buzzer-supplier.com/product_category/magnetic-buzzer(self-drive)_1533.html 1mm--9mm http://www.buzzer-supplier.com/product_category/1mm--9mm_1534.html 10mm--19mm http://www.buzzer-supplier.com/product_category/10mm--19mm_1535.html 20mm--29mm http://www.buzzer-supplier.com/product_category/20mm--29mm_1536.html Mechanical buzzer http://www.buzzer-supplier.com/product_category/mechanical-buzzer_1537.html 0-20mm http://www.buzzer-supplier.com/product_category/0-20mm_1538.html 21mm--29mm http://www.buzzer-supplier.com/product_category/21mm--29mm_1539.html 30mm--39mm http://www.buzzer-supplier.com/product_category/30mm--39mm_1540.html Piezo Ceramic Element http://www.buzzer-supplier.com/product_category/piezo-ceramic-element_1541.html
