Abstract

L'invention concerne un lecteur acoustique Bluetooth, comprenant un haut-parleur (6), une carte de circuits imprimés (5) comportant un circuit intégré Bluetooth, une batterie rechargeable (4) et un boîtier (1, 2) utilisé pour recevoir le haut-parleur (6), la carte de circuits imprimés (5) et la batterie (4). Un tapis antidérapant (10) est agencé sur le fond du boîtier (1, 2). Puisque le tapis antidérapant (10) est agencé sur le fond du boîtier (1, 2) et que le tapis antidérapant (10) a un coefficient de frottement élevé, le frottement entre le lecteur acoustique Bluetooth et la section de boîtier est accru et le lecteur acoustique Bluetooth ne glissera pas sur la section de boîtier même si le lecteur acoustique Bluetooth est utilisé dans une voiture qui se déplace normalement.
