Abstract
(EN)
The present invention addresses the problem of protecting a sound output unit without compromising sound volume. An alarm (10) comprises: a sound output unit (30) for generating sound and a housing (50) for storing the sound output unit (30). The housing (50) includes a shielding section (61c) and one or more air passages (P11). The shielding section (61c) has an airtight structure and covers the sound output unit (30). The one or more air passages (P11) transmit the sound from the sound output unit (30) to the outside of the housing (50) through an opening (51) located in a section different from the shielding section (61c).

La présente invention vise à protéger une unité de sortie sonore sans compromettre le volume sonore. À cet effet, la présente invention concerne une alarme (10) qui comprend : une unité de sortie sonore (30) pour générer un son et un boîtier (50) pour stocker l'unité de sortie sonore (30). Le boîtier (50) comprend une section de blindage (61c) et un ou plusieurs passages d'air (P11). La section de blindage (61c) a une structure étanche à l'air et recouvre l'unité de sortie sonore (30). Le ou les passages d'air (P11) transmettent le son de l'unité de sortie sonore (30) à l'extérieur du boîtier (50) à travers une ouverture (51) située dans une section différente de la section de blindage (61c).
