[0013] FIG. 1 is a block diagram illustrating an electronic device 101 in a network environment
100 according to various embodiments.
[0014] Referring to FIG. 1, the electronic device 101 in the network environment 100 may
communicate with an electronic device 102 via a first network 198 (e.g., a short-range
wireless communication network), or an electronic device 104 or a server 108 via a
second network 199 (e.g., a long-range wireless communication network). According
to an embodiment, the electronic device 101 may communicate with the electronic device
104 via the server 108. According to an embodiment, the electronic device 101 may
include a processor 120, memory 130, an input module 150, a sound output module 155,
a display module 160, an audio module 170, a sensor module 176, an interface 177,
a connecting terminal 178, a haptic module 179, a camera module 180, a power management
module 188, a battery 189, a communication module 190, a subscriber identification
module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the
components (e.g., the connecting terminal 178) may be omitted from the electronic
device 101, or one or more other components may be added in the electronic device
101. In some embodiments, some of the components (e.g., the sensor module 176, the
camera module 180, or the antenna module 197) may be implemented as a single component
(e.g., the display module 160). The processor 120 may execute, for example, software
(e.g., a program 140) to control at least one other component (e.g., a hardware or
software component) of the electronic device 101 coupled with the processor 120, and
may perform various data processing or computation. According to one embodiment, as
at least part of the data processing or computation, the processor 120 may store a
command or data received from another component (e.g., the sensor module 176 or the
communication module 190) in volatile memory 132, process the command or the data
stored in the volatile memory 132, and store resulting data in non-volatile memory
134. According to an embodiment, the processor 120 may include a main processor 121
(e.g., a central processing unit (CPU) or an application processor (AP)), or an auxiliary
processor 123 (e.g., a graphics processing unit (GPU), a neural processing unit (NPU),
an image signal processor (ISP), a sensor hub processor, or a communication processor
(CP)) that is operable independently from, or in conjunction with, the main processor
121. For example, when the electronic device 101 includes the main processor 121 and
the auxiliary processor 123, the auxiliary processor 123 may be adapted to consume
less power than the main processor 121, or to be specific to a specified function.
The auxiliary processor 123 may be implemented as separate from, or as part of the
main processor 121.
[0015] The auxiliary processor 123 may control at least some of functions or states related
to at least one component (e.g., the display module 160, the sensor module 176, or
the communication module 190) among the components of the electronic device 101, instead
of the main processor 121 while the main processor 121 is in an inactive (e.g., sleep)
state, or together with the main processor 121 while the main processor 121 is in
an active state (e.g., executing an application). According to an embodiment, the
auxiliary processor 123 (e.g., an image signal processor or a communication processor)
may be implemented as part of another component (e.g., the camera module 180 or the
communication module 190) functionally related to the auxiliary processor 123. According
to an embodiment, the auxiliary processor 123 (e.g., the neural processing unit) may
include a hardware structure specified for artificial intelligence model processing.
An artificial intelligence model may be generated by machine learning. Such learning
may be performed, e.g., by the electronic device 101 where the artificial intelligence
is performed or via a separate server (e.g., the server 108). Learning algorithms
may include, but are not limited to, e.g., supervised learning, unsupervised learning,
semi-supervised learning, or reinforcement learning. The artificial intelligence may
include a plurality of artificial neural network layers. The artificial neural network
may be a deep neural network (DNN), a convolutional neural network (CNN), a recurrent
neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network
(DBN), a bidirectional recurrent deep neural network (BRDNN), deep Q-network or a
combination of two or more thereof but is not limited thereto. The artificial intelligence
model may, additionally or alternatively, include a software structure other than
the hardware structure.
[0016] The memory 130 may store various data used by at least one component (e.g., the processor
120 or the sensor module 176) of the electronic device 101. The various data may include,
for example, software (e.g., the program 140) and input data or output data for a
command related thereto. The memory 130 may include the volatile memory 132 or the
non-volatile memory 134.

(e.g., the processor 120) of the electronic device 101, from the outside (e.g., a
user) of the electronic device 101. The input module 150 may include, for example,
a microphone, a mouse, a keyboard, a key (e.g., a button), or a digital pen (e.g.,
a stylus pen).
[0019] The sound output module 155 may output sound signals to the outside of the electronic
device 101. The sound output module 155 may include, for example, a speaker or a receiver.
The speaker may be used for general purposes, such as playing multimedia or playing
record. The receiver may be used for receiving incoming calls. According to an embodiment,
the receiver may be implemented as separate from, or as part of the speaker.
[0020] The display module 160 may visually provide information to the outside (e.g., a user)
of the electronic device 101. The display module 160 may include, for example, a display,
a hologram device, or a projector and control circuitry to control a corresponding
one of the display, hologram device, and projector. According to an embodiment, the
display module 160 may include a touch sensor adapted to detect a touch, or a pressure
sensor adapted to measure the intensity of force incurred by the touch.
[0021] The audio module 170 may convert a sound into an electrical signal and vice versa.
According to an embodiment, the audio module 170 may obtain the sound via the input
module 150, or output the sound via the sound output module 155 or a headphone of
an external electronic device (e.g., an electronic device 102) directly (e.g., wiredly)
or wirelessly coupled with the electronic device 101.
[0022] The sensor module 176 may detect an operational state (e.g., power or temperature)
of the electronic device 101 or an environmental state (e.g., a state of a user) external
to the electronic device 101, and then generate an electrical signal or data value
corresponding to the detected state. According to an embodiment, the sensor module
176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure
sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor,
a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor,
a humidity sensor, or an illuminance sensor.
[0023] The interface 177 may support one or more specified protocols to be used for the
electronic device 101 to be coupled with the external electronic device (e.g., the
electronic device 102) directly (e.g., wiredly) or wirelessly. According to an embodiment,
the interface 177 may include, for example, a high definition multimedia interface
(HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface,
or an audio interface.
[0024] A connecting terminal 178 may include a connector via which the electronic device
101 may be physically connected with the external electronic device (e.g., the electronic
device 102). According to an embodiment, the connecting terminal 178 may include,
for example, a HDMI connector, a USB connector, a SD card connector, or an audio connector
(e.g., a headphone connector).
[0025] The haptic module 179 may convert an electrical signal into a mechanical stimulus
(e.g., a vibration or a movement) or electrical stimulus which may be recognized by
a user via his tactile sensation or kinesthetic sensation. According to an embodiment,
the haptic module 179 may include, for example, a motor, a piezoelectric element,
or an electric stimulator.
[0026] The camera module 180 may capture a still image or moving images. According to an
embodiment, the camera module 180 may include one or more lenses, image sensors, image
signal processors, or flashes.
[0027] The power management module 188 may manage power supplied to the electronic device
101. According to one embodiment, the power management module 188 may be implemented
as at least part of, for example, a power management integrated circuit (PMIC).
[0028] The battery 189 may supply power to at least one component of the electronic device
101. According to an embodiment, the battery 189 may include, for example, a primary
cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel
cell.
[0029] The communication module 190 may support establishing a direct (e.g., wired) communication
channel or a wireless communication channel between the electronic device 101 and
the external electronic device (e.g., the electronic device 102, the electronic device
104, or the server 108) and performing communication via the established communication
channel. The communication module 190 may include one or more communication processors
that are operable independently from the processor 120 (e.g., the application processor
(AP)) and supports a direct (e.g., wired) communication or a wireless communication.
According to an embodiment, the communication module 190 may include a wireless communication
module 192 (e.g., a cellular communication module, a short-range wireless communication
module, or a global navigation satellite system (GNSS) communication module) or a
wired communication module 194 (e.g., a local area network (LAN) communication module
or a power line communication (PLC) module). A corresponding one of these communication
modules may communicate with the external electronic device via the first network
198 (e.g., a short-range communication network, such as Bluetooth
TM, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second
network 199 (e.g., a long-range communication network, such as a legacy cellular network,
a 5G network, a next-generation communication network, the Internet, or a computer
network (e.g., LAN or wide area network (WAN)). These various types of communication
modules may be implemented as a single component (e.g., a single chip), or may be
implemented as multi components (e.g., multi chips) separate from each other. The
wireless communication module 192 may identify and authenticate the electronic device
101 in a communication network, such as the first network 198 or the second network
199, using subscriber information (e.g., international mobile subscriber identity
(IMSI)) stored in the subscriber identification module 196.
[0030] The wireless communication module 192 may support a 5G network, after a 4G network,
and next-generation communication technology, e.g., new radio (NR) access technology.
The NR access technology may support enhanced mobile broadband (eMBB), massive machine
type communications (mMTC), or ultra-reliable and low-latency communications (URLLC).
The wireless communication module 192 may support a high-frequency band (e.g., the
mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication
module 192 may support various technologies for securing performance on a high-frequency
band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive
MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large
scale antenna. The wireless communication module 192 may support various requirements
specified in the electronic device 101, an external electronic device (e.g., the electronic
device 104), or a network system (e.g., the second network 199). According to an embodiment,
the wireless communication module 192 may support a peak data rate (e.g., 20Gbps or

mMTC, or U-plane latency (e.g., 0.5ms or less for each of downlink (DL) and uplink
(UL), or a round trip of 1ms or less) for implementing URLLC.
[0031] The antenna module 197 may transmit or receive a signal or power to or from the outside
(e.g., the external electronic device) of the electronic device 101. According to
an embodiment, the antenna module 197 may include an antenna including a radiating
element composed of a conductive material or a conductive pattern formed in or on
a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, the
antenna module 197 may include a plurality of antennas (e.g., array antennas). In
such a case, at least one antenna appropriate for a communication scheme used in the
communication network, such as the first network 198 or the second network 199, may
be selected, for example, by the communication module 190 (e.g., the wireless communication
module 192) from the plurality of antennas. The signal or the power may then be transmitted
or received between the communication module 190 and the external electronic device
via the selected at least one antenna. According to an embodiment, another component
(e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element
may be additionally formed as part of the antenna module 197.
[0032] According to various embodiments, the antenna module 197 may form a mmWave antenna
module. According to an embodiment, the mmWave antenna module may include a printed
circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the
printed circuit board, or adjacent to the first surface and capable of supporting
a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas
(e.g., array antennas) disposed on a second surface (e.g., the top or a side surface)
of the printed circuit board, or adjacent to the second surface and capable of transmitting
or receiving signals of the designated high-frequency band.
[0033] At least some of the above-described components may be coupled mutually and communicate
signals (e.g., commands or data) therebetween via an inter-peripheral communication
scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface
(SPI), or mobile industry processor interface (MIPI)).
[0034] According to an embodiment, commands or data may be transmitted or received between
the electronic device 101 and the external electronic device 104 via the server 108
coupled with the second network 199. Each of the electronic devices 102 or 104 may
be a device of a same type as, or a different type, from the electronic device 101.
According to an embodiment, all or some of operations to be executed at the electronic
device 101 may be executed at one or more of the external electronic devices 102,
104, or 108. For example, if the electronic device 101 should perform a function or
a service automatically, or in response to a request from a user or another device,
the electronic device 101, instead of, or in addition to, executing the function or
the service, may request the one or more external electronic devices to perform at
least part of the function or the service. The one or more external electronic devices
receiving the request may perform the at least part of the function or the service
requested, or an additional function or an additional service related to the request,
and transfer an outcome of the performing to the electronic device 101. The electronic
device 101 may provide the outcome, with or without further processing of the outcome,
as at least part of a reply to the request. To that end, a cloud computing, distributed
computing, mobile edge computing (MEC), or client-server computing technology may
be used, for example. The electronic device 101 may provide ultra low-latency services
using, e.g., distributed computing or mobile edge computing. In another embodiment,
the external electronic device 104 may include an internet-of-things (IoT) device.
The server 108 may be an intelligent server using machine learning and/or a neural
network. According to an embodiment, the external electronic device 104 or the server
108 may be included in the second network 199. The electronic device 101 may be applied
to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based
on 5G communication technology or IoT-related technology.
[0035] The electronic device according to various embodiments may be one of various types
of electronic devices. The electronic devices may include, for example, a portable
communication device (e.g., a smartphone), a computer device, a portable multimedia
device, a portable medical device, a camera, a wearable device, or a home appliance.
According to an embodiment of the disclosure, the electronic devices are not limited

[0133] Referring to FIG. 15, information about sound transmitted through the speaker 390
when the acoustic passage 420 is opened or closed by the opening device 430 may be
observed. Graph S1 is a graph representing sound information (e.g., dB) according
to frequency bands when the acoustic passage 420 is opened. Graph S2 is a graph representing
sound information (e.g., dB) according to frequency bands when the acoustic passage
420 is closed. It can be observed that when the acoustic passage 420 is opened, the
level (dB) of sound in the first frequency band (e.g., less than 3K) is higher than
when the acoustic passage 420 is closed. It can be observed that when the acoustic
passage 420 is opened, the level (dB) of sound in a second frequency band (e.g., 3K
to 5K) is lower than when the acoustic passage 420 is closed. Accordingly, the wearable
electronic device 300 according to various embodiments of the disclosure may control

a comparative embodiment in which control of an opening device is not performed. FIG.
16B is a graph of information about sound according to an embodiment of the disclosure
in which control of the opening device 430 is performed. Referring to FIG. 16A, it
can be observed that sound is amplified in a predetermined frequency band (e.g., 1000
to 10000 Hz) H1 by the sound transmitted through an acoustic passage. In the wearable
electronic device according to the comparative embodiment in FIG. 16A, howling may
occur due to the amplification of sound in the frequency band H1. Referring to FIG.
16B, in the wearable electronic device according to an embodiment of the disclosure,
sound is not amplified in the frequency band (e.g., 1000 to 10000 Hz) H2, and thus
howling does not occur.
[0135] FIGS. 17 and 18 are diagrams illustrating howling occurring in a wearable electronic
device according to a comparative embodiment. FIG. 17 is a diagram visually illustrating
howling that occurs when sound is amplified in a predetermined frequency band. FIG.
18 is a drawing illustrating that a frequency shift occurs due to the operation of
the wearable electronic device for removing the howling.
[0136] A wearable electronic device may be worn in the user's ear. The wearable electronic
device may include a housing in which a speaker and a microphone are disposed. The
speaker may output sound to the outside of the housing, and the microphone may receive
sound from the outside of the housing. The sound output to the outside of the housing
through the speaker may be received again by the microphone via an acoustic passage
formed inside the housing. When the acoustic passage is permanently opened, the sound
output to the outside of the housing through the speaker may be continuously received
by the microphone through the acoustic passage, thereby causing amplification in a
predetermined frequency band.
[0137] A problem to be solved in the disclosure may be to reduce noise in sound received
through a microphone.
[0138] A problem to be solved in the disclosure may be to control the transmission of sound
through an acoustic passage.
[0139] Problems to be solved in the disclosure are not limited to the aforementioned problems,
and may be variously defined without departing from the spirit and scope of the disclosure.
