1. An electronic device comprising:
a housing;
a speaker embedded in the housing;
a first sound path configured to transfer an output from the speaker to a user;
first hole formed in the housing;
second sound path connected to the first hole configured to transfer a external sound introduced through the first hole from outside the electronic device to the user; and
a variable hole member disposed in at least one of the first hole and the second sound path, the variable hole member comprising a conductive member comprising a conductive material, a deformable member comprising a deformable material, a first plate, and a second plate comprising a conductive material,
wherein the conductive member and the deformable member are disposed between the first plate and the second plate,
wherein the conductive member, the deformable member, the first plate, and the second plate form a second hole through which the external sound passes, and
wherein a size of the second hole varies according to a deformation of the deformable member when an electric signal is applied to the deformable member by the conductive member.
