Abstract (en)
[origin: WO2015091446A1] Accoustic enclosure (1) comprising: - a non heat-conducting external wall (20) defining at least in part a chamber (25), - at least one electrodynamic loudspeaker (5) comprising a motor (48), the loudspeaker having a peripheral portion (50) fixed on the external wall, and - at least one electronic control circuit (10) for the loudspeaker. The motor and the electronic circuit are linked to one and the same member (15) of the acoustic enclosure. The member is heat-conducting and comprises an exchange surface (66) able to be traversed by a heat flux (68) circulating in the member originating from the motor and from the electronic circuit when the acoustic enclosure is operational, the heat flux being intended to dissipate in the air (76) outside the acoustic enclosure or to pass into a heat-conducting element outside the acoustic enclosure.
