摘要：
The present invention provides an air massage device for a bed. The air massage device includes at least one air wave generator disposed on the bed. The air wave generator includes a shell, a permanent magnet disposed in the shell, a coil electromagnet movably disposed in the shell and a membrane attached to the coil electromagnet. When the coil electromagnet is powered by an alternating current, the coil electromagnet moves reciprocatingly relative to the permanent magnet along with the membrane so that the membrane generates an air wave which is adapted to massage people on the bed.
