A silencer device for a hair dryer comprises a container structure (2) exhibiting a plurality of inlet openings (8), an outlet opening (9) and a conduit (10) connecting the inlet (8) and outlet (9) openings to one another and further comprising a ring (14) made of sound-absorbent material, inserted

A silencer device for a hair dryer comprises a container structure (2) exhibiting a plurality of inlet openings (8), an outlet opening (9) and a conduit (10) connecting the inlet (8) and outlet (9) openings to one another and further comprising a ring (14) made of sound-absorbent material, inserted in the conduit (10) such as to interfere with a flow of air between the inlet openings (8) and the outlet (9) opening in such a way as to at least partly attenuate sound vibrations associated to the air flow. The inlet openings (8) are made on a lateral wall (6) of the container structure (2) and face the axis (X) such as to define an air flow along a first transversal direction to the axis (X) such as to define a flow of air along a first transversal direction to the axis (X), and deviating means (12) arranged in the conduit (10) impress an axial deviation along the axis (X) on the air flow coming from the inlet openings (8).
