30x15mm Piezoelectric Buzzer 200V-250V 5mA Beep 

30x15mm Piezoelectric Buzzer 200V-250V 5mA Beep Jiangsu Huawha Electronics Co., Ltd. was founded in 1999 and has devoted in the acoustic field for more than 20 years. There are about 200-300 employees including more than 20 professional and experienced engineers. The company is a reliable, well-developed and professional manufacturer of electronic acoustic products, providing electromagnetic buzzer,  speaker, Mylar Speaker, SMD Piezo Buzzer, Mechanical Buzzer, alarms and so on. The piezoelectric buzzer for Driver Circuit Built-in offer optimal sound, performance, and efficiency for all types of medical and industrial applications. Our piezo buzzers are constructed in a variety of sizes and work across varying frequencies which allows them to produce different sounds and tones. As voltage is applied to a piezo buzzer, the piezoceramic disc vibrates, flexing with respect to input voltage to generate sound. Our piezo buzzers maintain low current draw which is advantageous…
