Passive Buzzer Unit


Passive Buzzer Unit is a small-sized buzzer module that operates as a passive component, meaning it requires an external signal to produce sound. It is driven by a 4KHz signal and can emit sound with a maximum volume of up to 72dB when measured within a 10cm distance, based on the rating input power.Passive Buzzer Unit delivers impressive audio performance, producing clear and audible sound output. It is enclosed in a protective housing, which helps shield the internal components from external elements and provides durability.The module is designed to be compact in size, making it easy to integrate into various projects and devices. It consumes low power, which is beneficial for applications where energy efficiency is important. This module can be applied in a range of buzzer alarm scenarios where an audible alert or notification is required. It can be used in alarm systems, warning indicators, audible feedback mechanisms, and other applications that rely on sound-based alerts.
