Abstract

L'invention concerne un haut-parleur résonant comprenant un boîtier et, fixé à l'intérieur du boîtier, un haut-parleur résonant et une carte de circuit imprimé. Le boîtier est pourvu d'une rainure de haut-parleur pour tenir le haut-parleur résonant. Une ouverture de la rainure de haut-parleur est située au fond du boîtier. Le boîtier forme une cavité de structure cylindrique le long de la périphérie de la rainure de haut-parleur. Le boîtier a des bords allongés s'étendant vers l'extérieur le long de l'ouverture de la rainure de haut-parleur. Deux des bords allongés opposés l'un à l'autre sont pourvus de plis, formant ainsi des structures en arc. Un trou traversant est formé sur la paroi externe de la rainure de haut-parleur à une position proche de l'un des plis. La carte de circuit imprimé est connectée électriquement au haut-parleur résonant via le trou traversant. La présente invention permet non seulement au haut-parleur résonant d'être structurellement compact et de taille réduite, mais facilite également son utilisation et son transport.
