Buzzer in a Vacuum Vessel
DDAFRICA-001-0035
The Buzzer in a Vacuum Vessel is a compact alternative to the traditional Bell in a Jar apparatus, made of a strong acrylic vessel with a simple buzzer circuit. As the air is evacuated, the sound of the buzzer is attenuated.
Air is drawn out of the vessel through its outlet using a vacuum pump, which is not included. With no air to transmit the sound to the vessel walls, the buzzer becomes quieter, while the foam mounting reduces the sound passing to the walls through the buzzer's support.
Key Features
- Strong acrylic vessel with a simple buzzer circuit
- Buzzer mounted on foam to reduce sound transmission to the walls
- Outlet for evacuating air with a vacuum pump
- Vacuum pump not included
- Dimensions (H x dia): 14 x 10 cm
- Compact alternative to the Bell in a Jar apparatus
