Abstract

An electronic device is provided. The electronic device includes a housing including a front plate, a rear plate disposed to be spaced a predetermined distance apart from the front plate in parallel, and a side plate surrounding a space formed between the front plate and the rear plate, an opening disposed between an upper edge of the front plate and the side plate, a speaker including a sound radiation part in a direction of being directed toward the front plate and disposed inside the housing, a support member disposed to extend from the sound radiation part toward the upper edge of the front plate, and a pipeline including a space formed between the front plate and the support member. The pipeline may include a first structure disposed adjacent to the sound radiation part and a second structure disposed adjacent to the opening, and the second structure may be disposed to be spaced a predetermined length apart from the first structure in a direction of forming an acute angle with respect to a reference line orthogonal to the upper edge.
