Balanced membrane micromachined loudspeaker for hearing instrument application

Jörg Rehder, Pirmin Rombach, Ole Hansen

    Research output: Contribution to journalJournal articleResearchpeer-review


    Different actuator principles are rated with respect to an application as a loudspeaker in a hearing instrument. Fundamental rules are presented that have to be considered when different actuation principles are compared. A loudspeaker design using the most promising actuator principle, namely the balanced change in reluctance principle. is presented and first results of the production of planar coils are discussed.
