Investigations on dielectric elastomer loudspeaker drivers and flat panel loudspeakers

Research output: Contribution to journalConference articleContributedpeer-review



Electrodynamic loudspeaker technology is one of the oldest and most commonly used electroacoustic transducer technologies, because of several advantages of this technology. However, the material science and electronics made important progresses in the last decade. The progresses allow us to develop new type electroacoustic transducer technologies. The aim of the first part of talk is to give an overview on the recently developed loudspeaker or microphone technologies, such as graphene based, dielectric elastomer based, cellulose based, magnetorheological elastomer based, piezoelectric, metamaterial based technologies. The second part of the talk will focus on our recently developed solutions, such as dielectric elastomer actuators (DEA) as sound source in headphones and exciter integration into the fiber-reinforced and composite materials for flat panel loudspeaker applications. These both technologies offer some advantages for individual acoustic applications. The material and construction properties will be discussed with regard to the acoustical quality, amplitude, size and weight.
