WIPO Patent Application WO/2017/173624
Kind Code:
A1
Abstract:
Disclosed is a resonant loudspeaker comprising a housing and, fixed within the housing, a resonant speaker and a circuit board. The housing is provided with a speaker groove for holding the resonant speaker. An opening of the speaker groove is located at the bottom of the housing. The housing forms a cylindrically structured cavity along the periphery of the speaker groove. The housing has extended edges extending outwards along the opening of the speaker groove. Two of the extended edges opposite each other are provided with folds, thus forming arced structures. A through hole is provided on the outer wall of the speaker groove at a position in proximity to one of the folds. The circuit board is electrically connected to the resonant speaker via the through hole. The present invention not only makes the resonant loudspeaker to be overall structurally compact and reduced in size, but also facilitates use and carrying.
