Abstract: An electronic device is provided.

Abstract: An acoustic device and an electronic device including the same are provided. The acoustic device and an electronic device include a main body including at least one acoustic output port and at least one air vent port, a speaker unit accommodated in the main body, a first ear tip including at least one first opening area corresponding to the at least one air vent port and detachably coupled to the main body, and a second ear tip including at least one second opening area corresponding to the at least one air vent port and detachably coupled to the main body, wherein one of the first ear tip or the second ear tip may be coupled to the main body so that the main body is worn in a user's ear, and when the first ear tip is mounted, a larger area of the at least one air vent port may be exposed to an external space through the at least one first opening area than when the second ear tip is mounted.

Abstract: A wearable electronic device is provided. The wearable electronic device includes a speaker and a microphone, and more particularly, to a wearable electronic device worn on the user's ear. Various embodiments of the disclosure may provide a wearable electronic device including a first speaker configured to radiate a sound in a first frequency range, a second speaker configured to radiate a sound in a second frequency range higher than the first frequency range, a microphone, and a housing configured to accommodate the first speaker, the second speaker, and the microphone therein. The housing may include a sound path configured to serve as a path through which sounds radiated from the first speaker and the second speaker move, and a recess configured to communicate the sound path with the outside of the housing.
