Patent number: 8515118Abstract: A magnetic circuit includes an inner permanent magnet assembly and an outer permanent magnet assembly, a magnetically permeable yoke, and first and second air gap portions conducting first and second magnetic flux densities, respectively, the first and second air gap portions being adapted to receive first and second voice coil segments, respectively. The magnetic flux density in the first air gap portion is generated by superposition of magnetic flux generated by the inner permanent magnet assembly and magnetic flux generated by the outer permanent magnet assembly, and wherein the magnetic flux density in the second air gap portion is generated substantially exclusively by the inner permanent magnet assembly.Type: GrantFiled: August 17, 2012Date of Patent: August 20, 2013Assignee: Gettop Europe R&D ApSInventors: Kurt Sørensen, Andreas Sørensen, Morten Kjeldsen Andersen

Publication number: 20110299703Abstract: The present invention relates to a miniature transducer assembly for a wireless portable terminal. The miniature transducer assembly of the present invention comprises a transducer unit comprising a number of voice coils for displacing a diaphragm of said transducer unit. Moreover, the transducer assembly comprises at least one de-coupling coil for avoiding interference between the transducer unit and an antenna of the wireless portable terminal. In order to reduce the dimensions of the transducer assembly at least one de-coupling coil forms an integral part of a lead-out wire from of a voice coil.Type: ApplicationFiled: December 3, 2009Publication date: December 8, 2011Applicant: Gettop Europe R&D ApSInventors: Petteri Annamaa, Petri Huhtalo, Matti Niemi, Aki Lamponen, Yasser Amin, Morten Kjeldsen Andersen
