Description of SMD magnetic buzzer: 1 - LCP is applied as housing material with properties including heat resistance and acid-alkali resistance 2 - Well-chosen yellow grass is applied as lead pin material in order to provide best welding property to the product.

3 - Tiny size of the product adapts to more multiple PCB space design.

It meets the trend of making electronic products ultimately small and thin.

4 - Mature SMD design perfectly meets the SMT requirements which greatly improved welding efficiency.

5 - Steadily effective distance of sound output is very suitable for a wide range of portable electronic devices 6 - Rated square wave output and rated voltage are needed 7 - ROHS Directive-compliant Cooperating Company Through seven years effort, we have established long term cooperation with Haier, OPPO, Lenovo, Philips, TCL, BYD, etc.
