CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is based on and claims priority under 35 U.S.C. 119(a) of a Korean patent application number 10-2018-0134603, filed on Nov. 5, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND

The disclosure relates to a speaker module configured to output a sound by using a diaphragm, and to an electronic device (e.g., a portable communication device) including the speaker module.

2. Description of Related Art

With the increasing use of electronic devices, such as portable terminals (e.g., smartphones), modules that perform various functions have come to be provided in such electronic devices.

For example, an electronic device may include a speaker module in order to output various sounds.

The speaker module may convert an electric signal generated by an electronic device into a sound that can be heard by a user, and thus may output the sound.

SUMMARY

In order to smoothly transmit a sound output from the speaker module to the outside of an electronic device, it is required to align a sound hole of the speaker module with a hole (e.g., a speaker hole) disposed in the electronic device.
