The housing (310) may be formed by combining an upper housing (310a) and a lower housing (310b) to form a single housing, and may form a space for mounting various components therein. For example, audio components (e.g., a speaker or a microphone) and electronic components (e.g., a battery, a power management module, a wireless communication module) may be placed inside the housing (310).

[0060] According to one embodiment, the wearable electronic device (300) may have an asymmetrical shape, as illustrated in FIG. 3(b). The reason the wearable electronic device (300) is formed to have an asymmetrical shape is partly due to ergonomic considerations, but in terms of securing acoustic performance, the arrangement relationship between the acoustic components and electronic components within the housing (310) may be given priority.

[0061] A wearable electronic device (300) according to various embodiments of the present disclosure may be a device that can be worn on a part of the body, for example, on the ear or head. Examples of the wearable electronic device (300) may include an in-ear earset (or in-ear headset) and a hearing aid, and in addition, various product groups equipped with speakers or microphones may be included.

[0062] In the various drawings of the present disclosure, as an example of a wearable electronic device (300), a canal-type in-ear earset, which is primarily mounted in the external auditory canal extending from the auricle to the eardrum, may be described as the target. However, it should be noted that the present invention is not limited thereto. In another embodiment, although not depicted in the drawings, the wearable electronic device (300) may also be an open-type earset mounted on the auricle.

[0063] Referring to FIGS. 3(a) and 3(c) together, a wearable electronic device (300) (e.g., 101 of FIG. 1) may be integrated into an electronic device (e.g., 102 of FIG. 1) or may be configured separately from the electronic device (e.g., 102 of FIG. 1). The electronic device (e.g., 102 of FIG. 1) herein may correspond to various types of devices. The electronic device (e.g., 102 of FIG. 1) may include, for example, a smartphone, a mobile phone, a navigation device, a game console, a TV, a head unit for a vehicle, a notebook computer, a laptop computer, a tablet computer, a personal media player (PMP), a personal digital assistant (PDA), a portable communication device, a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or various home appliance devices. The electronic device according to the embodiment of the present document is not limited to the above-described devices.

[0064] A wearable electronic device (300) can be connected to an electronic device (e.g., 102 of FIG. 1) wired or wirelessly. In this case, the wearable electronic device (300) can, in a relationship with the electronic device (e.g., 102 of FIG. 1), function as an audio output interface (or an audio output device (e.g., 155 of FIG. 1)) that outputs an audio signal generated in the electronic device (e.g., 102 of FIG. 1) to the outside. Additionally or alternatively, the wearable electronic device (300) disclosed in the present document can also function as an audio input interface (or an input device (e.g., 150 of FIG. 1)) for receiving an audio signal corresponding to a sound acquired from the outside of the electronic device (e.g., 102 of FIG. 1).

[0065] Hereinafter, it can be described as an example that the wearable electronic device (300) is provided separately from the electronic device (e.g., 102 of FIG. 1). Accordingly, in the following embodiments, the electronic device (e.g., 102 of FIG. 1) may be referred to as an “external electronic device (e.g., 102 of FIG. 1)” in the sense that it may be provided separately from the wearable electronic device (300). Referring to FIG. 3(c), the wearable electronic device (300) may also be connected to the external electronic device (e.g., 102 of FIG. 1) by a wire. In this case, the wearable electronic device (300) may communicate with the external electronic device using a cable (350). As an embodiment different from FIG. 3(a), the wearable electronic device (300) may additionally be provided with a connection portion (340) for connecting the cable (350). According to one embodiment, one end of the cable (350) may be connected to the wearable electronic device (300), and the other end of the cable (350) may be connected to a connection terminal (not shown) formed on an external electronic device. As a result, an electronic device external to the wearable electronic device (300) may be directly connected.

[0066] When a wearable electronic device (300) is wirelessly connected to an external electronic device (e.g., 102 of FIG. 1) (e.g., FIG. 3(a)), the wearable electronic device (300) can communicate with the external electronic device via a network (e.g., a short-range wireless communication network or a long-range wireless communication network). The network may be, but is not limited to, a mobile or cellular communication network, a local area network (LAN) (e.g., Bluetooth communication), a wireless local area network (WLAN), a wide area network (WAN), the Internet, a small area network (SAN), etc.

[0067] A wearable electronic device (300) may include a communication module. In addition, according to various embodiments, the wearable electronic device (300) may further include at least one of a power management module, a sensor module, a battery, and an antenna module. In an embodiment in which the wearable electronic device (300) is wirelessly connected to an external electronic device, the communication module may be a wireless communication module. In addition, in addition to the components according to the above-described embodiments, the wearable electronic device (300) according to various embodiments may further include an audio module (e.g., 170 of FIG. 1), and may be integrated into a compact structure inside the housing (310) of the wearable electronic device (300).

Descriptions of each component of the audio module included in the wearable electronic device (300) will be omitted to the extent that they overlap with the embodiment described above in FIG. 2.

[0068] According to one embodiment, the wearable electronic device (300) may not communicate with an external electronic device. In this case, the wearable electronic device (300) may be implemented to receive a signal corresponding to a sound acquired from the outside according to the operation (or control) of the components included in the wearable electronic device (300) itself without being controlled by an external electronic device, and to output an acoustic signal to the outside. For example, the wearable electronic device (300) may be a stand-alone electronic device that plays music or a video on its own without communicating with an external electronic device, outputs a sound corresponding thereto, or receives and processes a user's voice.

[0069] According to another embodiment, the wearable electronic device (300) may communicate with and / or be controlled by an external electronic device. The wearable electronic device (300) may be an interaction-type electronic device that is paired with an external electronic device, such as a smart phone, through a communication method such as Bluetooth, and converts data received from the external electronic device to output sound or receives a user's voice and transmits it to the external electronic device.
