Abstract: An electronic device according to an embodiment of the disclosure may include a support bracket, a display disposed on the front surface of the support bracket, a printed circuit board disposed on the rear surface of the support bracket, a sound output module, an electronic component disposed on the printed circuit board and generating heat during operation, and a heat transfer unit disposed between the display and the support bracket and configured to transfer the heat generated from the electronic component. The heat transfer unit may be configured to provide a portion of a sound output passage through which sound generated from the sound output module passes.

Abstract: According to an embodiment of the disclosure, an electronic device may include a housing positioned at a front surface thereof and including a first part made of a non-metallic material; a first support member disposed in the housing and including a first opening having at least a portion facing the first part; a speaker unit disposed in the housing and configured to face the first opening of the first support member; a sound hole formed in the housing to emit a sound output to the speaker unit; a first sealing member disposed between the first support member and the speaker unit and configured to enclose a sound emission port of the speaker unit and the first opening of the first support member; a first sound channel formed by being enclosed by the first sealing member and configured to connect the first opening and the speaker unit; and a second sound channel positioned between the first support member and the first part and configured to connect the first opening and the sound hole.

Abstract: A motor structure according to one embodiment of the present disclosure may comprise: a shaft; a hollow magnet formed with the shaft at the center thereof; and a rotation part that rotates with respect to the shaft, and that is divided into a first region, which is divided with respect to the shaft, and a second region, which is the region excluding the first region. The rotary part can include: a coil assembly operating together with the magnet so as to generate electromagnetic force; a counterweight which is positioned in the first region and which is a first weight; and a metal member of which at least one portion is positioned in the second region, and which is a second weight that is lighter than the first weight.
