Abstract (en)
[origin: WO2015195952A1] An improved electrically conductive membrane pump/transducer. The electrically conductive pump/transducer includes an array of electrically conductive membrane pumps that combine to generate a desired sound by moving a membrane (such as a membrane of PDMS), a piston, and/or by the use of pressurized airflow in the absence of such a membrane or piston. The electrically conductive membranes in the array can be, for example, graphene-polymer membranes. The electrically conductive pump can include mid-range, tweeter, and sub-woofer speakers.
