Title: Wiert Kopinga: Innovator in Electroacoustic Transducer Technology

Introduction

Wiert Kopinga is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of electroacoustic transducers, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

One of his latest patents is a magnet system for an electroacoustic transducer. This invention comprises a diaphragm equipped with conductors and a magnet system featuring permanent magnetic zones on both sides of the diaphragm. The design aims to produce an energizing field at the location of the conductors. Additionally, auxiliary magnetic fields are generated at the boundary areas of the magnetic zones to minimize stray fields. This results in improved concentration of the energizing magnetic fields in the diaphragm's plane, leading to a stronger magnetic field at the conductors' location.

Another significant patent by Kopinga is a mechanical filter for an electrodynamic transducer. This invention incorporates a mechanical filter as a coupling element between a voice coil former and a cone. The goal is to achieve a frequency characteristic with a high-frequency roll-off that begins at a lower frequency. A part of the centering diaphragm situated within the periphery of the voice coil former is utilized as the mechanical filter.
