Abstract:
1. An audio speaker comprising: at least one valve-less electrostatic pump, wherein each of the at least one valve-less electrostatic pumps comprises: (a) an electrically conductive membrane; (b) a first solid electrically conductive stator located on a first side of the electrically conductive membrane; (c) a second solid electrically conductive stator located on a second side of the electrically conductive membrane; (d) a plurality of first support material members located between the electrically conductive membrane and the first solid electrically conductive stator; (e) a plurality of second support material members located between the electrically conductive membrane and the second solid electrically conductive stator; (f) a first cross-sectional airflow area located between the plurality of the first support material members, the first solid electrically conductive stator, and the electrically conductive membrane; and (g) a second cross-sectional airflow area located between the plurality of the second support material members, the second solid electrically conductive stator, and the electrically conductive membrane, wherein
