9x4.2mm Magnetic Buzzer 3V 16ohm 80db 100mA 2700Hz
Our products are widely used in home appliances, medical devices, cars, cordless phones, electric bicycles, computers, alarm systems. We are able to make 7 to 9 million pieces monthly based on our professional engineers, advanced audio analyzers, ISO 9001, ISO 140001 and QS 9000 certifications.
Magnetic Buzzer Self-drive Type, also known as indicators, are designed with an internal drive circuit for easy application integration. During operation, current is driven through a voice coil to produce a magnetic field. When a voltage is applied, the coil generates a magnetic field and then allows the diaphragm to vibrate and produce sound. This Buzzer type has a low operating voltage ranging from 1.5 – 12V+. Our magnetic buzzers are desirable for applications requiring a lower sound pressure level (SPL) and frequency.
From product designing, purchasing and testing, every step is controlled strictly by our QC staffs in order to make sure the perfect quality of our products. Currently, over 70% products are exported to US. South East Asia and Europe.
With professional skills, enthusiasm and ambition, we are looking forward to corporate with you. Welcome to Huawha!
