Fully symmetrical single-suspension electrodynamic loudspeaker using a Halbach array

Conference Papers

Abstract

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

Loudspeaker

A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A speaker system, also often simply referred to as a speaker or loudspeaker, comprises one or more such speaker drivers, an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound.

Electrodynamic speaker driver

An electrodynamic speaker driver, often called simply a speaker driver when the type is implicit, is an individual transducer that converts an electrical audio signal to sound waves. While the term is sometimes used interchangeably with the term speaker (loudspeaker), it is usually applied to specialized transducers which reproduce only a portion of the audible frequency range. For high fidelity reproduction of sound, multiple loudspeakers are often mounted in the same enclosure, each reproducing a different part of the audible frequency range.

Classical architecture

Classical architecture usually denotes architecture which is more or less consciously derived from the principles of Greek and Roman architecture of classical antiquity, or sometimes more specifically, from the works of the Roman architect Vitruvius. Different styles of classical architecture have arguably existed since the Carolingian Renaissance, and prominently since the Italian Renaissance. Although classical styles of architecture can vary greatly, they can in general all be said to draw on a common "vocabulary" of decorative and constructive elements.
