Abstract
A fluid pump is disclosed with a fluid pump housing, a first pole piece having a first polarity and positioned within the fluid pump housing, an opposing pole piece having a second polarity different from the first polarity, positioned within the fluid pump housing and spaced from the first pole piece, a wire coil comprising a coiled electrically conductive wire comprising a first end and a second end, the wire coil movably positioned between the first pole piece and the opposing pole piece, at least one membrane coupled between the fluid pump housing and the wire coil, the membrane configured to move responsive movement of the wire coil through elongation of a membrane suspension section, and at least one vent extending through a wall of the fluid pump housing to an fluid chamber immediately adjacent to the at least one membrane.
