Abstract
The invention relates to a hair dryer including a tapered plastic shell between a rear end and a front end through which flows out the air set into motion and heated by the hair dryer, this plastic shell defining at least one air inlet and an air outlet and being intended to accommodate at least one motor and one fan, the shaft of which is borne by an attached internal structure in the central portion of the fuselage. According to the invention, the plastic shell is conformed in order to receive the air between the air inlet and the internal structure bearing the fan, on a longer acoustic path as compared with the length of the acoustic path between the rear end and the internal structure bearing the fan.
