This electronic buzzer has several advantages over other styles of buzzers, including being more insect resistant, more power efficient, and allowing for multiple tone settings.

The GM-A0256BL is made of an ABS composite plastic that has superior physical properties when compared to other plastics and is also resistant to various temperatures and water. It has a standard working voltage of 12VDC and can work at the frequency range of 1.5K-4KHz. The typical sound level at a distance of 10cm is about 70dB and it also has an IP65 rating for weather resistance.

The GM-A0256BL works by vibrating a thin cardboard diaphragm that is attached to its frame using magnets. When an electric current passes through the diaphragm, it vibrates, creating a sound that is heard by the operator. The sound that is created depends on the size and type of diaphragm and the frequency of the current that is passed through. As the frequency of the current varies, the sound produced changes accordingly.

The GM-A0256BL is designed for many applications, including industrial machines, fire alarms, vehicle alarms, emergency call systems, and communication systems. It is also used in public places such as movie theatres, offices, shopping malls, airports, schools, and hospitals.
