Description

Electronic device including speaker and microphone Various embodiments of the present disclosure relate to an electronic device including a speaker and a microphone. At least one component related to acoustic effects may be mounted in the electronic device. The components related to acoustic effects may include, for example, speakers and microphones, and these components may be mounted inside the housing of the electronic device, having various shapes and arrangement structures corresponding to the various external designs of the electronic device. A wearable electronic device is disclosed that includes a speaker and a microphone, and is capable of being worn in a portion close to the user's ear, such as in-ear earphones (or headsets) or hearing aids. In such a wearable electronic device, a microphone disposed inside a housing may be provided to perform an active noise cancellation (ANC) function. The ANC function may be a function that receives sound waves using a microphone, inverts the phase of these waves, and then outputs the phase-inverted waves through a speaker to block noise. By performing the ANC function, noise generated inside or outside the wearable electronic device can be eliminated by destructive interference.
