Abstract

L'invention porte sur un microphone (40) d'un dispositif micro-casque qui comprend un élément de support de capteur (46) pour supporter une partie convexe (46B) dans un état séparé d'un boîtier de microphone (41) afin de transmettre une vibration à un capteur de vibration (47), une pluralité d'éléments circulaires (46D1) ayant différents diamètres étant formés au niveau d'une unité de support (46D) de l'élément de support du capteur (46). L'élément de support du capteur (46) est fait d'un matériau élastique. Ainsi, la partie convexe (46B) (le capteur de vibration) est dans un état flottant contre le boîtier du microphone (41). Même dans le cas où une vibration de glissement entre un crochet auriculaire et une oreille et analogue est générée côté crochet auriculaire, l'unité de support (46D) (chaque rainure circulaire (46D1)) de l'élément de support du capteur (46) absorbe la vibration, de sorte que la transmission d'une vibration de l'extérieur au capteur de vibration (47) est restreinte.
