Abstract

L'invention concerne un bouchon d'oreille Bluetooth (10), une oreillette Bluetooth (20) et une boîte de charge (30). Le bouchon d'oreille Bluetooth (10) comprend une unité de production de son, une carte de commande principale et une batterie, un module Bluetooth étant prévu sur la carte de commande principale. Le bouchon d'oreille Bluetooth comprend en outre un corps d'écouteur principal (11) qui peut être placé dans la cavité de la conque auriculaire d'une oreille humaine, une surface avant du corps d'écouteur principal (11) étant pourvue d'une cavité sonore (12), et un tube de guidage de son (13) est disposé sur la cavité sonore (12) ; et un manchon d'oreille (14) est installé de manière amovible sur le tube de guidage de son (13), et une ailette (15) est disposée sur le corps d'écouteur principal (11). Lorsque le bouchon d'oreille Bluetooth (10) prévu dans la présente solution est porté, le manchon d'oreille (14) peut être étiré dans le canal auditif externe de l'oreille humaine, le corps d'oreillette principal (11) et la cavité sonore (12) peuvent être placés dans la cavité de la conque auriculaire de l'oreille humaine, et l'ailette (15) peut être placée dans la cymba de la conque auriculaire de l'oreille humaine, de façon à empêcher le bouchon d'oreille Bluetooth de tomber. Comme l'ailette est agencée sur le corps d'oreillette principal, le corps d'oreillette principal et/ou la cavité sonore peuvent être fabriqués pour être relativement petits, ce qui permet de réduire la quantité d'espace occupé.
