Claims

[Scope of Claim for Utility Model Registration] A noise-reducing structure that prevents noise generated from a sound-producing object such as a cooling fan disposed inside the housing 20 from leaking outside the device, comprising an outer wall portion 1, an inner wall portion 2, and the like. and a connecting frame 6 that connects the outer wall part 1 and the inner wall part 2.
A cavity 3 formed therebetween, an intake hole 11 communicating from the outside of the outer wall 1 to the cavity 3, and an intake hole 11 communicating with the cavity 3 from the outside of the outer wall 1 to the inside of the housing 20 from the cavity 3 opened at the end of the inner wall 2. A sound deadening structure for an electronic device, characterized in that a sound deadening cover 5 is disposed on a side surface of the casing 20, and a flow path for cooling air 10 is formed by a communicating exhaust hole 13.
