Abstract
A sleeping system is provided, including an air bladder and a diaphragm pump. The diaphragm pump communicates with the air bladder. The diaphragm pump includes a base, a first inlet, a first outlet, a first noise-eliminating foam, a pump body and a cover. The first inlet is formed on the base. The first outlet is formed on the base. The first noise-eliminating foam is disposed in the base. The cover is connected to the base and covers the pump body, wherein air flow passes through the first inlet into the base and travels through the pump body and the first noise-eliminating foam, and leaves the diaphragm pump through the first outlet to be infused into the air bladder.
