Abstract
A blower comprises a housing, an inlet to receive air, an outlet to deliver a flow of air and a deformable member configured to pump a chamber. The deformable member may be configurable to a first configuration and a second configuration, for example by electrical energy that may be applied as current or voltage. The blower may comprise a plurality of chambers, wherein each chamber may be compressed out of phase with each other, for example such that the flow rate of the generated air flow may not fluctuate as much. In other forms, the blower may comprise a plurality of chambers that vary in size.
