This electronic buzzer alarm is a self contained audible signaling device that integrates a multivibrator, a piezoelectric buzzer chip, an impedance adjustment unit, a resonator and a case to provide reliable audible alerts. Key benefits - Clear audible notification: The multivibrator drives the piezo buzzer to vibrate and output an audio signal for reliable signaling. - Tone customization: Impedance adjustment allows tuning the buzzer tone to suit different devices and environments. - Continuous operation: When connected to the rated power, the buzzer sounds continuously for persistent alerts. - Durable construction: Built with high quality materials and housed in a protective case for dependable use. - Easy integration: Designed for seamless inclusion in systems that require an audible alert. Performance and operation - Function: The integrated multivibrator vibrates and outputs an audio signal via the piezo buzzer chip. - Tone control: Impedance adjustment controls the piezoelectric buzzer tone to match application needs. - Power and duration: Continuous sound occurs when connected to the rated power. Applications - Security and alarm systems for buildings or safes. - Household appliances and timers that require an audible alert. - Industrial equipment and warning indicators in factories or process lines.
