<p>A hand-held electronic device includes a casing (1) having a first face (11) and a second face (12) opposite to the first face (11). The casing (1) includes an interior intermediate the first face (11) and the second face (12) of the casing (1). A first cover (2) includes a thickness forming an annular periphery (21) and abuts the first face (11) of the casing (1). A joining area between the annular periphery (21) of the first cover (2) and the first face (11) of the casing (1) includes a junction section (C1) having at least one vent (5a, 5b, 5c) in communication with the interior of the casing (1). An electronic component (3) is mounted in the interior of the casing (1). A cooling fan (4) is mounted in the interior of the casing (1). The cooling fan (4) guides air currents via the at least one vent (5a, 5b, 5c) to cool the electronic component (3).</p> |
