Invented at the end of the XIXth century, the electrodynamic loudspeaker has not much changed since then. Although the materials have greatly evolved, the geometry and the transduction principle stay the same. In many applications, the presence of two sets of suspension and the bulkiness of the driver behind the membrane are drawbacks of the classical architecture. The search for a very flat loudspeaker has also been very motivated by several industries. In this paper, we introduce a new kind of flat, purely symmetrical with regards to the membrane, single suspension Halbach array loudspeaker. The simulation results presented here show the promising characteristics of our loudspeaker prototype.
