Abstract

L'invention porte sur un lecteur MP3 comprenant un boîtier comportant une carte à circuits, un écran d'affichage relié à la carte à circuits et une batterie rechargeable pour fournir une puissance à la carte à circuits. Des colonnes de trou de vis utilisées pour fixer la carte à circuits sont disposées à l'intérieur du boîtier. Des trous de vis correspondant aux colonnes de trou de vis sont disposés sur la carte à circuit. La carte à circuits est fixée avec des vis à l'intérieur du boîtier. En raison du fait que la carte à circuits est fixée avec les vis à l'intérieur du boîtier et que les vis sont fermement fixées, la carte à circuits est empêchée de se balancer à l'intérieur du boîtier, ce qui garantit ainsi un fonctionnement normal du lecteur MP3.
