Patent

CA 2436464

The invention provides an electroacoustic transducer such as a speaker, a headphone, an earphone, a microphone, an acoustic wave sensor, etc., which is able to set a distribution of magnetic fluxes capable of uniformly driving the entire diaphragm in a wide range of a conductor formed on the diaphragm and with respect to the vibration direction thereof, does not require any high machining accuracy during production, and is able to efficiently convert electric signals into sounds or sounds into electric signals at a low distortion level. The electroacoustic transducer 20 includes magnet plates 21 and 22, the entirety of which are formed like a disk or a ring; and an acoustic diaphragm 23 disposed parallel to said magnet plates 21 and 22 and having a conductor formed on the plane thereof; wherein a component parallel to the vibration plane of said acoustic diaphragm 23 is zero or in the radius direction of said magnet plates 21 and 22 in the direction of magnetizing respective partial areas of said magnet plates 21 and 22, and angles formed by said magnetizing direction with respect to the vibration plane of said acoustic diaphragm 23 are made gradually different from each other in accordance with the distance from the center axis of said magnet plates 21 and 22.

L'invention concerne un convertisseur électroacoustique (20), notamment un haut-parleur, un casque téléphonique, un casque d'écoute, un microphone et un capteur acoustique, pouvant établir la distribution d'un flux magnétique permettant à un diaphragme d'être entraîné de façon uniforme sur la totalité de sa surface sur un conducteur formé sur le diaphragme dans un large domaine de directions de vibration, et de convertir un signal électrique en son, ou un son en signal électrique, avec une faible distorsion, sans nécessité d'une précision élevée d'usinage à la fabrication. Ce convertisseur comprend des plateaux magnétiques (21, 22), généralement en forme de disque ou d'anneau, et le diaphragme acoustique (23), disposé de façon parallèle aux plateaux magnétiques (21, 22), comportant le conducteur formé sur sa surface, un composant parallèle à la surface vibrante du diaphragme acoustique (23), dans les directions de magnétisation dans les zones partielles des plateaux magnétiques (21, 22) étant zéro ou formé dans la direction radiale des plateaux magnétiques (21, 22), les angles des directions de magnétisation relatives à la surface vibrante du diaphragme acoustique (23) étant différentiés graduellement l'un de l'autre en fonction de la distance des plateaux magnétiques (21, 22) par rapport à leur axe central.
