Description

Electronic device including heat transfer portion forming sound output channel Technical Field The present disclosure relates to an electronic device comprising a heat transfer unit configured to provide a sound output channel. Background An electronic device (e.g., a portable electronic device) may include a heat generating component (e.g., an application processor) that generates heat during operation and a heat transfer unit (e.g., a soaking plate) for improving heat dissipation performance. The heat generating component and the heat transfer unit of the electronic device may be provided with a support interposed therebetween. The heat generated from the heat generating component may be transferred to the heat transfer unit via the support. The heat transfer unit may be used to spread heat transferred from a heat generating component of the electronic device to other areas of the electronic device. For the purpose of aiding in the understanding of the present disclosure, the above information may be provided as a related art. None of the above is to be claimed as prior art to the present disclosure nor is it to be used to determine prior art. Disclosure of Invention Technical problem The electronic device may include a sound output module configured to output sound and a sound output channel through which sound generated by the sound output module passes. Because the display may be made of a relatively fragile material, the electronic device may include a plate that is disposed separate from the display to define the sound output channel through which sound passes. For example, at least a portion of the sound output channel may be defined by a separate plate made of stainless steel. When a separate board defines a portion of the sound output channel, the manufacturing cost of the electronic device may increase. Solution to the problem An electronic device according to an embodiment of the present disclosure may include a support bracket, a display, a printed circuit board, a sound output module, an electronic component, and a heat transfer unit. In an embodiment, the display may be placed on the front surface of the support bracket. In an embodiment, the printed circuit board may be placed on a rear surface of the support bracket. In an embodiment, the electronic components may be placed on a printed circuit board and may generate heat during operation. In an embodiment, the heat transfer unit may be disposed between the display and the support bracket, and may be configured to transfer heat generated from the electronic part. In an embodiment, the heat transfer unit may be configured to provide a portion of a sound output channel through which sound generated from the sound output module passes. An electronic device according to an embodiment of the present disclosure may include a support bracket, a display, an electronic component, and a heat transfer unit. In an embodiment, the heat transfer unit may comprise a plate and a flow space surrounded by the plate. In an embodiment, at least a portion of the plate may provide a portion of a sound output channel through which sound propagates. Advantageous effects of the invention In the electronic device according to the embodiment of the present disclosure, the sound output channel through which the sound passes may be provided by extending a portion of the heat transfer unit. An electronic device according to embodiments of the present disclosure does not require a separate board to provide a sound output channel through which sound passes. Accordingly, since the sound output channel does not require a separate board, the manufacturing cost of the electronic device can be reduced and the manufacturing process can be simplified.
