Title
(EN) Sounding device, voice coil thereof and winding method of voice coil
(ZH) 发声器件及其音圈和音圈的绕制方法
Abstract
(EN) The invention provides a sounding device, a voice coil thereof and a winding method of the voice coil. The voice coil comprises a first voice coil and a second voice coil; the first voice coil comprises a first inner layer and a first outer layer formed on the side, away from a through hole, of the first inner laye; the first inner layer is provided with a first protruding part which protrudes outof the first outer layer along the axis direction of the through hole and forms a first accommodating groove together with the first outer layer; the second voice coil comprises a second inner layerwhich abuts against the first inner layer and forms a through hole with the first inner layer, and a second outer layer which is formed at one side, far away from the through hole, of the second innerlayer; the second outer layer is provided with a second protruding part protruding out of the second inner layer in the axis direction of the through hole and forming a second containing groove withthe second inner layer; the first accommodating groove completely contains and fixes the second protruding part; and the second accommodating groove completely contains and fixes the first protrudingpart. According to the sound production device, the voice coil thereof and the winding method of the voice coil, the influence of the first voice coil on the second voice coil is reduced, so that thepurpose that the voice coil is regular is achieved, and the performance of the voice coil is improved.
(ZH) 本发明提供了一种发声器件及其音圈和音圈的绕制方法,音圈包括第一音圈及第二音圈,第一音圈包括第一内层以及成型于第一内层远离通孔一侧的第一外层,第一内层具有沿通孔的轴线方向凸出于第一外层并与第一外层围合形成第一收容槽的第一凸部,第二音圈包括与第一内层抵接并与第一内层围合形成通孔的第二内层以及成型于第二内层远离通孔一侧的第二外层,第二外层具有沿通孔的轴线方向凸出于第二内层并与第二内层围合形成第二收容槽的第二凸部,第一收容槽完全收容并固定第二凸部,第二收容槽完全收容并固定第一凸部。本发明的发声器件及其音圈和音圈的绕制方法减少了第一音圈对第二音圈的影响,从而达到音圈规整的目标以提高音圈的性能。
