Abstract

La présente invention concerne une électronique audio miniature comprenant un boîtier utilisé pour fixer une carte de circuit principale, un interrupteur à bouton poussoir situé sur la carte de circuit imprimé principale pour commander une mise sous tension/hors tension de l'électronique audio miniature, un trou d'évitement d'interrupteur disposé dans la partie inférieure du boîtier et servant à éviter le bouton poussoir ; ainsi qu'un bouton poussoir de commutation emmanché sur l'interrupteur à bouton poussoir, le bouton poussoir de commutation comprenant une partie de manchon emmanchée sur l'interrupteur à bouton poussoir, un bloc coulissant qui est plus grand que le trou d'évitement d'interrupteur, et une poignée qui est plus petite que le trou d'évitement d'interrupteur. Selon la présente invention, étant donné que le bouton poussoir de commutation est emmanché sur l'interrupteur à bouton poussoir, la partie de manchon du bouton poussoir de commutation est emmanchée sur l'interrupteur à bouton poussoir, et le bloc coulissant du bouton poussoir de commutation est plus grand que le trou d'évitement d'interrupteur, le bloc coulissant du bouton poussoir de commutation est disposé dans la partie inférieure du boîtier pour bloquer le trou d'évitement de commutation, la poussière ne peut pas pénétrer dans l'électronique audio miniature par le trou d'évitement d'interrupteur. L'interrupteur à bouton poussoir s'actionne par l'intermédiaire de la poignée du bouton poussoir de commutation, ce qui permet de faciliter le fonctionnement.
