Abstract

<abstract abstract-type="graphical" xml:lang="en" id="smll201402982-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A low‐voltage driven thermoacoustic speaker</bold> is fabricated based on three‐dimensional graphene foams synthesized by a nickel‐template assisted chemical vapor deposition method. The corresponding thermoacoustic performances are found to be related to its microstructure. Graphene foams exhibit low heat‐leakage to substrates and feasible tunability in structures and thermoacoustic performances, having great promise for applications in flexible or ultrasonic acoustic devices. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjn22tsbs" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
