The vibration frequency determines the output tone, with maximum SPL at the resonant frequency (~2.3kHz). An external drive circuit provides the AC signal, allowing frequency and amplitude control. The piezo element converts electrical energy directly to mechanical vibration without a coil.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Positive<\/td><td>Drive signal input<\/td><\/tr><tr><td>2<\/td><td>Negative<\/td><td>Ground \/ return<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Home appliance alert tones<\/li><li>Medical device alarm beeps<\/li><li>Industrial equipment status sounds<\/li><li>Security system warnings<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Spec1<\/th><th>Spec2<\/th><\/tr><tr><td>PKMMCS1218C-Q0<\/td><td>Murata<\/td><td>12mm piezo<\/td><td>SMD<\/td><\/tr><tr><td>CEM-1203(42)<\/td><td>CUI Devices<\/td><td>12mm magnetic<\/td><td>THT<\/td><\/tr><tr><td>PS1240P02BT<\/td><td>TDK<\/td><td>12mm piezo<\/td><td>SMD<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9731","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=9731"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9731\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=9731"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=9731"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=9731"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=9731"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
