Abstract[English]
A helmet speaker system includes a helmet shell (102) with a helmet impact liner (104) inside the helmet shell. A hole (110) is formed in the helmet impact liner (104), the hole penetrating through the helmet impact liner (104). A speaker (130) is fixed in the hole (110). A space (108) formed between the helmet impact liner (104) and the interior sidewall of the helmet shell (102) is directly acoustically connected to a rear portion of the speaker (130) fixed in the hole (110). The speaker is configured to use the space to produce improved sound, particularly with respect to low frequency sound.[French]
La présente invention concerne un système de haut-parleur pour casque comprenant une coque de casque (102) avec une doublure d'amortissement de casque (104) à l'intérieur de la coque de casque. Un trou (110) est formé dans la doublure d'amortissement de casque (104), le trou traversant la doublure d'amortissement de casque (104). Un haut-parleur (130) est fixé dans le trou (110). Un espace (108) formé entre la doublure d'amortissement de casque (104) et la paroi latérale intérieure de la coque de casque (102) est directement relié acoustiquement à une partie arrière du haut-parleur (130) fixée dans le trou (110). Le haut-parleur est conçu pour utiliser l'espace pour produire un son amélioré, en particulier en ce qui concerne les basses fréquences.
