This branch of acoustic engineering deals with the design of headphones, [[microphone]]s, [[loudspeaker]]s, sound systems, sound reproduction, and recording.<ref>{{cite web|last=Acoustical Society of America|title=Acoustics and You (A Career in Acoustics?)|url=http://asaweb.devcloud.acquia-sites.com/education_outreach/careers_in_acoustics|access-date=21 May 2013|archive-url=https://web.archive.org/web/20150904010934/http://asaweb.devcloud.acquia-sites.com/education_outreach/careers_in_acoustics|archive-date=2015-09-04|url-status=dead}}</ref> There has been a rapid increase in the use of portable electronic devices which can reproduce sound and rely on electroacoustic engineering, e.g. [[mobile phone]]s, [[portable media player]]s, and [[tablet computer]]s.

The term "electroacoustics" is also used to describe a set of electrokinetic effects that occur in heterogeneous liquids under influence of ultrasound.<ref name="dukhin2002">Dukhin, A.S. and Goetz, P.J.
