            Micro-vibration sensors, sometimes referred to as bone-conduction microphones or vibration pickup capsules, are becoming increasingly relevant in product categories that require stable sound capture in challenging conditions. These sensors detect solid-borne mechanical vibration, enabling applications that conventional air-conducted microphones cannot reliably support. One commonly used model in vibration pickup applications is the ECM-B9745AL70-318A (9.7 mm vibration microphone capsule), which provides […]<\/p>\n","protected":false},"author":1,"featured_media":3671,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[400],"tags":[533,518,521,532],"class_list":["post-3670","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-product-guides","tag-contact-microphone","tag-high-spl","tag-o9-7mm","tag-vibration-pickup"],"_links":{"self":[{"href":"https:\/\/ecmicrophones.com\/ko\/wp-json\/wp\/v2\/posts\/3670","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ecmicrophones.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ecmicrophones.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ecmicrophones.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ecmicrophones.com\/ko\/wp-json\/wp\/v2\/comments?post=3670"}],"version-history":[{"count":0,"href":"https:\/\/ecmicrophones.com\/ko\/wp-json\/wp\/v2\/posts\/3670\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ecmicrophones.com\/ko\/wp-json\/wp\/v2\/media\/3671"}],"wp:attachment":[{"href":"https:\/\/ecmicrophones.com\/ko\/wp-json\/wp\/v2\/media?parent=3670"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ecmicrophones.com\/ko\/wp-json\/wp\/v2\/categories?post=3670"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ecmicrophones.com\/ko\/wp-json\/wp\/v2\/tags?post=3670"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
