An electronic device comprising a housing that defines an internal volume of which one part only is occupied by electronic components and which is provided with at least two ventilation openings in two portions of the housing separated from one another so as to allow the circulation of air in the internal volume between these two openings, the electronic components comprising at least one loudspeaker that has a useful frequency range and that is mounted in the internal volume opposite at least one diffusion opening provided in the housing, characterised in that each ventilation opening is linked to the internal volume by a baffle channel having a length designed to a form a Helmholtz resonator having a resonance frequency located within the useful frequency range of the loudspeaker. |
