Ironless Loudspeakers
TL;DR: In this paper, the authors proposed an ironless structure of a classical loudspeaker motor to eliminate the reluctance effect and eddy currents caused by the iron in the motor, which can be optimized to create uniform, high-level induction in the space where the coil moves.

A flexible, transparent and ultrathin single-layer graphene earphone
TL;DR: In this article, a flexible, transparent and ultrathin earphone based on single-layer graphene (SLG) is reported, which operates in the frequency range of 20 Hz to 200 kHz and has a highest sound pressure level (SPL) of 70 dB at a 1 cm distance.
Journal ArticleDOI
Time-varying non linear modeling of electrodynamic loudspeakers
TL;DR: In this article, a nonlinear analytical modeling of the electrodynamic loudspeaker is proposed to take into account the variations of Small signal parameters (R e, L e, Bl, R ms, M ms, C ms ) with respect to both time and input current.

Ironless and Leakage Free Voice-Coil Motor Made of Bonded Magnets
TL;DR: In this paper, two ironless and leakage free structures are presented, one using traditional sintered magnets and the other one using bonded magnets, giving the pros and cons of each solution.

Diagnosis and Remedy of Nonlinearities in Electrodynamical Transducers
TL;DR: In this article, a case study based on a set of drivers intended for woofer application is presented, where large-signal parameters based on extended transducer modeling and measured by system identification techniques reveal the physical causes, allow an objective assessment of the performance and give indications for practical improvements.
