摘要 |
<p>A cup (1) has a convex configuration and the distance between the diametric surface (3) of a neodymium magnet (2) and the internal surface (4) of the cup allows forming of a toroidal chamber (5) with a large air volume to achieve good cooling ventilation of the mobile bobbin and to prevent compression phenomena acting on the loudspeaker.</p> |
