Electronic device including stylus pen and method for controlling microphone of the same

An electronic device comprising:

• a housing;
• at least one first microphone disposed within the housing and exposed through a first portion of the housing;
• a first wireless communication circuit disposed within the housing;
• an elongated hole formed in a second portion of the housing;
• a stylus pen detachably insertable into the elongated hole and including a second microphone;
• a processor disposed within the housing and functionally connected to the at least one first microphone and the first wireless communication circuit;
• and
• a memory disposed within the housing and functionally connected to the processor,
• wherein the memory stores instructions that are executable by the processor to cause the electronic device to:
• when the stylus pen is located in the elongated hole, operate both the at least one first microphone and the second microphone to detect sound, and
• when the stylus pen is not located in the elongated hole, operate only the second microphone to detect sound.

A method for controlling a first microphone of an electronic device, the method comprising:

• identifying, by a sensor circuit, whether a stylus pen is located within an elongated hole formed in a housing of the electronic device;
• when the stylus pen is located within the elongated hole, operating the first microphone and a second microphone of the stylus pen to detect sound;
• and
• using only the second microphone when the stylus pen is removed from the elongated hole.
