Abstract

L'épaisseur de ce récepteur radio portatif est réduite autant que faire se peut. Des bornes de connexion (3) permettant d'envoyer les signaux sonores à un écouteur (2) sont constituées en motif conducteur près de l'arête extérieure du boîtier (1) du récepteur. Un cordon relie l'écouteur (2) à un organe de fixation (5) lui-même rattaché, mais non à demeure, au boîtier (1). L'organe de fixation (5) est pourvu de deux bras repliés vers l'intérieur qui assurent une prise solide sur l'arête extérieure du boîtier (1). Sur la face interne de l'organe de fixation (5), se trouvent, en outre, des bornes de connexion destinées à l'envoi de signaux à l'écouteur (2) et, lorsque les bornes de connexion (3) sont entrées en contact avec les bornes de connexion du boîtier (1), les signaux sonores sortis du récepteur sont envoyés à l'écouteur (2). Dans la mesure où l'organe (5)est aisément détachable, il est possible de ne l'attacher au boîtier, à proximité des bornes de connexion (3), qu'au moment d'utiliser ce récepteur radio portatif.
