Description

Wearable electronic device and method of operation thereof

[0001] The present disclosure relates to a wearable electronic device and a method of operating the same.

[0002] Portable electronic devices (e.g., wearable electronic devices) that provide various functions are being developed to satisfy consumers' purchasing desires. With the advancement of display technology, wearable electronic devices have been developed that include displays (e.g., augmented reality glasses, or human mounted devices) capable of implementing extended reality (XR) or augmented reality (AR). Wearable electronic devices that include displays capable of implementing extended reality (XR) or augmented reality (AR) can combine virtual images displayed on the display with real scenes (e.g., external images, external real-world images) to be perceived by the user's eyes. Users can simultaneously view virtual images displayed on the display and real scenes (e.g., external images, or external real-world images), and can experience extended reality or augmented reality by combining virtual images with real scenes (e.g., external images, or external real-world images).

[0003] A wearable electronic device may include an audio module that outputs sound. Sound output from the wearable electronic device may leak out, and if another person approaches the user, the leaked sound may be heard by that person. The user may reduce the volume of the wearable electronic device to prevent sound from leaking to others, and by reducing the volume, the loudness of the sound the user wishes to hear may also be reduced.

[0004] Embodiments of the present disclosure may provide a wearable electronic device and a method of operating the same that can prevent sound output from a speaker module of a wearable electronic device from being heard by other people outside.

[0005] Embodiments of the present disclosure can detect when another person approaches within a certain distance (e.g., a designated distance) of a wearable electronic device worn by a user. When another person is present within a certain distance, the wearable electronic device and a method of operation thereof can be provided so that the sound is not heard by another person outside without reducing the volume of the sound output from the speaker module of the wearable electronic device.

[0006] Embodiments of the present disclosure can detect when another person approaches within a certain distance (e.g., a designated distance) of a wearable electronic device worn by a user. When another person is present within the certain distance, the opening and closing of at least one port (or port hole) formed in an audio module can be controlled to prevent sound from being heard by another person outside, thereby providing a wearable electronic device and a method of operation thereof.

[0007] Embodiments of the present disclosure may provide a wearable electronic device and a method of operation thereof that, when another person approaches a wearable electronic device worn by a user within a certain distance (e.g., a designated distance), controls the opening and closing of at least one port formed in an audio module according to the location of the other person so that sound is not heard by another person outside.

[0008] The technical tasks intended to be accomplished in this document are not limited to those mentioned above, and other technical tasks not mentioned can be clearly understood by a person skilled in the art to which this document belongs from the description below.

[0013] A wearable electronic device and a method of operation thereof according to an embodiment of the present disclosure can detect when another person approaches within a certain distance (e.g., a designated distance) of a wearable electronic device worn by a user. When another person is present within a certain distance, the opening and closing of at least one port formed in an audio module can be controlled so that sound is not easily heard by another person outside.

[0014] A wearable electronic device and a method of operation thereof according to an embodiment of the present disclosure can control the opening and closing of at least one port formed in an audio module according to the location of another person when another person approaches within a certain distance (e.g., a designated distance) of a wearable electronic device worn by a user, so that sound cannot be heard clearly by another person outside.

[0015] The wearable electronic device and the method of operation thereof according to the embodiment of the present disclosure can protect the user's privacy by reducing the leakage of sound heard by the user to an external user.

[0069] In the present disclosure, 'extended reality (XR)' or 'augmented reality' may mean overlaying a computer-generated virtual image onto a physical, real-world environment or a real-world object to display it as a single image.

[0070] In the present disclosure, the term "extended reality (XR) display device" or "augmented reality display device" refers to a device capable of combining and displaying virtual images with real reality. It may encompass not only virtual reality glasses or augmented reality glasses in the form of glasses worn by a user, but also head-mounted display apparatus, extended reality helmet, or augmented reality helmet. Such extended reality display devices or augmented reality display devices are usefully utilized in daily life for purposes such as information retrieval, navigation, or camera shooting. Furthermore, wearable electronic devices in which an extended reality device or augmented reality display device is implemented in the form of glasses can be worn as a fashion item and used for both indoor and outdoor activities.

[0071] In the present disclosure, a ‘real scene’ (e.g., external image, or external real image) is a scene of the real world viewed by an observer or user through a wearable electronic device (e.g., XR glasses, AR glasses, extended reality display, or augmented reality display) and may include real world objects.

[0072] In the present disclosure, a virtual image may be an image generated through a display unit. The virtual image may include both static and dynamic images. Such an AR image (or virtual image) may be an image that is overlaid on a real-world scene (e.g., external image, or external real-world image) to display information about real-world objects within the real-world scene (e.g., external image, or external real-world image), information about the operation of an extended reality device or an augmented reality device, or a control menu, etc.

[0073] FIG. 2a is a drawing showing a wearable electronic device according to one embodiment of the present disclosure.

[0074] FIG. 2b is a block diagram of a wearable electronic device according to one embodiment of the present disclosure.

[0075] Referring to FIGS. 1, FIGS. 2a and FIGS. 2b, the wearable electronic device (106) may include at least a portion of the electronic device (101) of FIG. 1.

[0076] According to one embodiment, the wearable electronic device (106) may include glasses-type XR (extended reality) glasses, AR (augmented reality) glasses, VR (virtual reality) glasses, or MR (mixed reality) glasses.

[0077] According to one embodiment, a user (201) may wear a wearable electronic device (106) (e.g., an extended reality electronic device or a virtual reality electronic device). According to one embodiment, the wearable electronic device (106) may include a processor (120) (e.g., the processor (120) of FIG. 1), a memory (130) (e.g., the memory (130) of FIG. 1), an artificial intelligence module (290), at least one sensor (280), and / or a speaker module (200).

[0078] According to one embodiment, the speaker module (200) of the wearable electronic device (106) can also be applied to a bar-type electronic device (e.g., a bar-type smartphone), a foldable-type electronic device (e.g., a foldable-type smartphone), or a tablet electronic device.

[0079] For example, the speaker module (200) may include a housing forming an outer case (e.g., the housing (270) of FIG. 2c), at least one dynamic vent section (210, 220), a speaker section (250) (e.g., a speaker and a speaker circuit), a first port (260) (e.g., a main port), and at least one second port (230) (e.g., a sub port).

[0080] For example, the speaker module (200) can be worn on the user's (201) ear (202) (e.g., placed close to it) to output sound to the user's (210) ear (202).

[0081] According to one embodiment, at least one sensor (280) may include various sensors for sensing a person approaching within a certain distance (e.g., a specified distance) and a person located within a certain distance.

[0082] For example, at least one sensor (280) may include a LiDAR (Light Detection and Ranging) sensor.

[0083] For example, at least one sensor (280) may include a camera such as a tracking camera. The tracking camera is a camera used for detection and spatial recognition of 3 degrees of freedom (DoF) or 6 DoF, and may include a GS (global shutter) camera. Since a stereo camera is required for head tracking and spatial recognition, the tracking camera may include two cameras (e.g., a first recognition camera and a second recognition camera).

[0084] For example, at least one sensor (280) may include at least one microphone for sensing ambient sound of the wearable electronic device (106).

[0085] For example, sensing data (e.g., sensing result) from at least one sensor (280) can be provided to the processor (120).

[0086] According to one embodiment, a processor (120) (e.g., a processing circuit) may be implemented as one or more IC (integrated circuit (or circuitry)) chips and may perform various data processing operations. The processor (120) may include at least one electrical circuit and may process instructions (or programs, data) stored in memory (130) individually or collectively in a distributed manner. The processor (120) may include a processor assembly comprising one or more processing circuits. The processor (120) may include any processing circuit that is operative to control the performance and operations of one or more components of the electronic device (101) (e.g., memory (130), display module (160), sensor module (176) (e.g., sensor), camera module (180) (e.g., image sensor) and / or communication module (190) (e.g., communication circuit)). For example, a processor (120) (e.g., an application processor (AP)) may be implemented as a system on chip (SoC) (e.g., a single chip or a chipset). For example, the processor (120) may be implemented as a plurality of cores (or at least one core circuit), a plurality of chips, or a plurality of chipsets. For example, the processor (120) may include one or more processing circuits. For example, the processor (120) may include one or more processing circuits configured to perform the various functions of the present disclosure individually and / or collectively. As an example without limitation, at least a portion of the processor (120) may be included in a first chip of an electronic device (101, 106), and at least another portion of the processor (120) may be included in a second chip of an electronic device (101, 106) different from the first chip of the electronic device (101, 106).

[0087] According to one embodiment, the number of processors (120) may be one or more. For example, the processor (120) may have the structure of a multi-core processor such as a dual core, quad core, hexa core, or octa core. The processor (120) can control the operations of electronic devices (101, 106) by executing instructions stored in memory (130). For example, the processor (120) may correspond to a plurality of processors that collectively perform a plurality of operations by dividing them among the processors.

[0088] According to one embodiment, the wearable electronic device (106) can generate a three-dimensional (3D) map of the surrounding environment by operating a LiDAR sensor of at least one sensor (280).

[0089] For example, the wearable electronic device (106) can determine in real time the relative position, relative distance, and angle of a person located within a certain distance from the user wearing the wearable electronic device (106) by operating the LiDAR sensor of at least one sensor (280). The wearable electronic device can acquire in real time information regarding the relative position, relative distance, and angle of a person located within a certain distance from the user wearing the wearable electronic device (106) by operating the LiDAR sensor of at least one sensor (280).

[0090] According to one embodiment, the wearable electronic device (106) can track the position of a person's face and ears located within a certain distance of a user wearing the wearable electronic device (106) by operating a tracking camera (e.g., a vision sensor) of at least one sensor (280).

[0091] For example, the wearable electronic device (106) can track the position of the face and ears of a person in the vicinity located within a certain distance of the user, and obtain detailed directional data of the person in the vicinity based on the result of tracking the position of the face and ears of the person in the vicinity.

[0092] According to one embodiment, a wearable electronic device (106) can generate high-precision location information by combining information on the relative position, relative distance, and angle of a person within a certain distance of a user obtained by operating a LiDAR sensor, and detailed directional data of a person within a certain distance of a user wearing the wearable electronic device (106) obtained by operating a tracking camera (e.g., a vision sensor).

[0093] According to one embodiment, the wearable electronic device (106) can check the location of a person nearby by operating a camera (e.g., a tracking camera) in addition to a LiDAR sensor. Therefore, even if the wearable electronic device (106) does not include a LiDAR sensor, the location of a person nearby can be checked by operating a camera (e.g., a tracking camera).

[0094] According to one embodiment, the artificial intelligence module (290) of the wearable electronic device (106) can learn high-precision location information generated by combining information on the relative position, relative distance, and angle of a person in the vicinity located within a certain distance from the user, and detailed directional data of a person in the vicinity located within a certain distance from the user.

[0095] For example, the artificial intelligence module (290) can generate meaningful feature data of the location, distance, angle, or size of a person located within a certain distance of the wearable electronic device (106) using a feature engineering method. For example, the artificial intelligence module (290) can estimate the directionality of the person's ear based on the generated feature data.

[0096] For example, the artificial intelligence module (290) can generate label data by measuring the reduction effect of sound leakage by direction using an initial data labeling method and providing feedback (satisfaction / dissatisfaction, etc.) to reduce sound leakage.

[0097] For example, the artificial intelligence module (290) can classify the volume reduction value by direction and whether the volume reduction in a specific direction is satisfactory or unsatisfactory based on a regression, classification, and reinforcement learning model.

[0098] For example, the artificial intelligence module (290) can obtain control information of dynamic vents to optimize the control of opening or closing of multiple dynamic vents based on feedback from the user.

[0099] For example, the artificial intelligence module (290) can provide control information for the dynamic vent section to the processor (120). The processor (120) can control the opening or closing of a plurality of dynamic vent sections (210, 220) in real time based on the control information for the dynamic vent section obtained from the artificial intelligence module (290).

[0100] For example, the artificial intelligence module (290) can perform reinforcement learning for controlling the opening or closing of a plurality of dynamic vents by reflecting user feedback on controlling the opening or closing of a plurality of dynamic vents (210, 220).

[0101] The artificial intelligence module (290) provides control information of the dynamic vent section obtained as a result of reinforcement learning to the processor (120) so that the control of opening or closing of the multiple dynamic vent sections (210, 220) can be optimized.

[0102] According to one embodiment, a person may be an object identified as a human based on at least one of a biosignal, facial shape, and / or thermal characteristics among external object(s) detected by a sensor. In one embodiment of the present disclosure, a person may be used interchangeably with an external object having a feature point associated with a human.

[0103] FIGS. 2c to 2e are drawings showing a speaker module worn on a user's ear.

[0104] Referring to FIGS. 2a through 2e, according to one embodiment, the first port (260) may be formed so that sound output from the speaker unit (250) is output toward the user's ear (202). For example, at least a portion of the first port (260) may be open so that sound is output toward the user's ear (202). For example, the first port (260) may be positioned on the front of the speaker unit (250) (e.g., in a direction close to the user's eardrum). For example, the first port (260) may be acoustically coupled to the external environment as well as the eardrum of the user (201) as a main port.

[0105] According to one embodiment, the housing (270) may include an inner surface positioned to face the user's body (e.g., head or ear) when the wearable electronic device (106) is worn, and an outer surface positioned opposite the inner surface or exposed to the outside. In this case, a first port (260) may be formed on the inner surface to output sound in a first direction, and a second port (230) may be formed on the outer surface or side to output sound in a second direction.

[0106] According to one embodiment, the second port (230) is formed such that sound output from the speaker part (250) is output to the outside of the speaker module (200) through a first port hole (232, 2nd port1) and / or second porthole (234, 2 nd It may include port2).

[0107] For example, the first port hole (232) and the second port hole (234) of the second port (230) may be positioned on the rear of the speaker part (250) (e.g., opposite the direction of the user's eardrum).

[0108] For example, the processor (120) can operate at least one sensor (280) to sense whether a person is located within a certain distance (e.g., a predetermined distance). At least one sensor (280) can provide sensing data (e.g., a sensing result) to the processor (120). Based on the sensing data (e.g., a sensing result), the processor (120) can determine whether a person is detected within a certain distance (e.g., whether a person is located within a certain distance).

[0109] For example, when a person is detected within a certain distance (e.g., a designated distance), the processor (120) can operate at least one of the plurality of dynamic vents (210, 220) to control the sound leaking through the first port hole (232) and / or the second port hole (234).

[0110] For example, the first dynamic vent portion (210) may be positioned so that the degree of opening or closing of the first port hole (232) can be adjusted. For example, the first dynamic vent portion (210) may operate to open or close the first port hole (232) based on the control of the processor (120). For example, the first port hole (232) may be formed on the lower part of the -z axis of the housing (270).

[0111] For example, the processor (120) can operate the first dynamic vent (210) so that the first port hole (232) is opened when a person is detected within a certain distance (e.g., a designated distance) so that the leaked sound is not heard by the surrounding people (or the leaked sound is canceled out). For example, the processor (120) can control the degree of opening and closing of the first dynamic vent (210) so that the sound leaking in that direction can be attenuated according to the location or direction of the surrounding people. For example, the processor (120) can control the degree (%) of opening (or closing) of the first dynamic vent (210). For example, the processor (120) can control the degree (%) of opening (or closing) of the first dynamic vent (210) to form a location (null point) where the leaked sound is canceled out based on the result of confirming the location of the surrounding people. Through this, sound with the inverse phase of the sound output through the first port (260) can be output to the outside through the second port (230), thereby canceling out the sound leaking from the first port (260).

[0112] For example, the processor (120) can operate the first dynamic vent (210) so that the first porthole (232) is closed if no person is detected within a certain distance (e.g., a specified distance).

[0113] For example, the second dynamic vent (220) may be positioned so that the degree of opening or closing of the second port hole (234) can be adjusted. For example, the second dynamic vent (220) may operate to open or close the second port hole (234) based on the control of the processor (120). For example, the second port hole (234) may be formed on the upper part of the z-axis of the housing (270).

[0114] For example, the processor (120) can operate the second dynamic vent (220) so that the second port hole (234) is opened (open) so that the leaked sound is not heard by the surrounding people (or the leaked sound is canceled out) when a person is detected within a certain distance (e.g., a predetermined distance). For example, the processor (120) can control the degree of opening and closing of the second dynamic vent (220) so that the sound leaking in that direction can be attenuated according to the location or direction of the surrounding people. For example, the processor (120) can control the degree (%) of opening (or closing) of the second dynamic vent (220). For example, the processor (120) can control the degree (%) of opening (or closing) of the second dynamic vent (220) to form a location (null point) where the leaked sound is canceled out based on the result of confirming the location of the surrounding people. Through this, sound with the inverse phase of the sound output through the first port (260) can be output to the outside through the second port (230), thereby canceling out the sound leaking from the first port (260).

[0115] For example, the processor (120) can operate the second dynamic vent (220) so that the second porthole (234) is closed if no person is detected within a certain distance (e.g., a specified distance).

[0116] For example, the processor (120) can operate at least one sensor (280) to obtain direction and distance information of a person located within a certain distance (e.g., a specified distance).

[0117] For example, the processor (120) can operate the first dynamic vent (210) to control the degree to which the first port hole (232) is opened or closed based on direction and distance information of a person located within a certain distance (e.g., a specified distance) so that the leakage sound is not heard by people nearby (or so that the leakage sound is canceled out).

[0118] For example, the processor (120) can operate the second dynamic vent (220) to control the degree to which the second porthole (234) is opened or closed based on direction and distance information of a person located within a certain distance (e.g., a specified distance) so that the leakage sound is not heard by people nearby (or so that the leakage sound is canceled out).

[0119] For example, sound output from the speaker unit (250) can be output towards the user's ear (202) through the first port (260). Sound output through the first port (260) may leak out, but when the first dynamic vent unit (210) operates and the first port hole (232) opens, sound is output to the outside through the first port hole (232), and the sound output through the first port (260) may be canceled out. Sound output through the first port (260) may leak out, but when the second dynamic vent unit (220) operates and the second port hole (234) opens, sound is output to the outside through the second port hole (234), and the sound output through the first port (260) may be canceled out.

[0120] FIG. 3a is a drawing showing a first state (open state) of a dynamic vent portion (e.g., a dynamic vent portion of a piezoelectric element type) of a wearable electronic device according to one embodiment of the present disclosure.

[0121] FIG. 3b is a drawing showing a first state (closed state) of a dynamic vent portion (e.g., a dynamic vent portion of a piezoelectric element type) of a wearable electronic device according to one embodiment of the present disclosure.

[0122] Referring to FIGS. 2a, 2b, 2e, FIGS. 3a, and FIGS. 3b, according to one embodiment, a speaker module (200) of a wearable electronic device (106) according to one embodiment of the present disclosure may include a plurality of dynamic vent portions (300) (e.g., a first dynamic vent portion (210) of FIG. 2e, or a second dynamic vent portion (220)). FIGS. 3a and 3b show one dynamic vent portion (300) among the plurality of dynamic vent portions (300).

[0123] For example, the dynamic vent section (300) may include a dynamic vent section of the piezoelectric element type that operates as an actuator according to an electrical signal. The dynamic vent section (300) may be opened when in a first state. For example, the dynamic vent section (300) may be closed when in a second state.

[0124] For example, the second electrode (340) (e.g., piezo electrode) can operate as an actuator by the potential difference applied to the first electrode (330) (e.g., base electrode) and the second electrode (340) (e.g., piezo electrode).

[0125] For example, when the switch (350) is turned off by control of the processor (120), the dynamic vent (300) operates in a first state so that the first contact (310) and the second contact (320) can be separated. When the first contact (310) and the second contact (320) are separated, the first port hole (232) or the second port hole (234) can be opened.

[0126] For example, when the switch (350) is turned on by control of the processor (120), the dynamic vent (300) operates in a second state so that the first contact (310) and the second contact (320) can be closed. When the first contact (310) and the second contact (320) are closed, the first port hole (232) or the second port hole (234) can be closed.

[0127] For example, the degree to which the first contact (310) and the second contact (320) are opened (or closed) (e.g., the ratio of opening and closing (%)) can be controlled by adjusting the potential difference applied to the first electrode (330) (e.g., base electrode) and the second electrode (340) (e.g., piezo electrode).

[0128] Figure 4a is a diagram showing the position of the eardrum according to the open and closed states of the dynamic vent.

[0129] FIG. 4b is a diagram showing the sound pressure level (SPL) of leakage sound according to the open and closed states of the dynamic vent section.

[0130] Referring to FIG. 2e, FIG. 4a and FIG. 4b, according to one embodiment, the first port hole (232) may be opened or closed depending on the operation of the first dynamic vent portion (210). For example, the degree to which the first dynamic vent portion (210) is opened (or closed) (e.g., the ratio of opening to closing (%)) may be controlled.

[0131] According to one embodiment, the second port hole (234) may be opened or closed depending on the operation of the second dynamic vent section (220). For example, the degree to which the second dynamic vent section (220) is opened (or closed) (e.g., the ratio of opening to closing (%)) may be controlled.

[0132] For example, the first dynamic vent (210) may operate in a first state (open state) to open the first port hole (232), and the second dynamic vent (220) may operate in a second state (close state) to close the second port hole (234). In this case, as shown in FIG. 4b, the average sound pressure level (430) (SPL) of the leakage sound may be reduced as at least a portion of the second port (e.g., the second port (230) in FIG. 2b and FIG. 2e) is opened. At this time, as shown in FIG. 4a, the change in the average sound pressure level (430) (SPL) at the eardrum of the user may be small.

[0133] For example, the second dynamic vent (220) may operate in a first state (open state) to open the second port hole (234), and the first dynamic vent (210) may operate in a second state (close state) to close the first port hole (232). In this case, as shown in FIG. 4b, as at least a portion of the second port (230) is opened, the average sound pressure level (420) (SPL) of the leakage sound may be reduced. At this time, as shown in FIG. 4a, the change in the average sound pressure level (420) (SPL) at the eardrum of the user may be small.

[0134] According to one embodiment, if either the first port hole (232) or the second port hole (234) is opened, the average sound pressure level (410, 430) of the leakage sound can be reduced. Additionally, if both the first port hole (232) and the second port hole (234) are opened, the average sound pressure level (410, 430) of the leakage sound can be further reduced. For example, the first dynamic vent section (210) and the second dynamic vent section (220) may operate in an open state so that both the first port hole (232) and the second port hole (234) are opened. In this case, as illustrated in FIG. 4b, as the second port is opened, the average sound pressure level (SPL) of the leakage sound can be reduced. At this time, as shown in FIG. 4a, the change in the average sound pressure level (SPL) at the eardrum of the user may be small.

[0135] For example, the first dynamic vent section (210) and the second dynamic vent section (220) may operate in a second state (close state) so that both the first port hole (232) and the second port hole (234) are closed. In this case, as shown in FIG. 4b, the second port is closed, and the average sound pressure level (410) (SPL) of the leakage sound may increase relatively compared to when at least one of the first port hole (232) and the second port hole (234) is open. At this time, as shown in FIG. 4a, the change in the average sound pressure level (410) (SPL) at the eardrum of the user may be small.

[0136] FIGS. 5a to 5c are drawings showing the distribution of sound pressure levels (SPL) of leakage sound according to the open and closed states of the dynamic vent section.

[0137] Referring to FIG. 2e and FIG. 5a to 5c, according to one embodiment, the first dynamic vent section (210) and the second dynamic vent section (220) may operate in a second state (close state) so that both the first port hole (232) and the second port hole (234) may be closed. In this case, the second port is closed, so the average sound pressure level (SPL: sound pressure level) of the leakage sound (510, 520) may be about 40[dB] to about 60[dB]. Therefore, the average sound pressure level (SPL: sound pressure level) of the leakage sound (510, 520) may be relatively increased compared to when at least one of the first port hole (232) and the second port hole (234) is open.

[0138] According to one embodiment, the first dynamic vent (210) operates in a first state (open state) and the second dynamic vent (220) operates in a second state (close state), so that the first port hole (232) can be opened. At this time, the second port hole (234) can be closed. In this case, the first port hole (232) of the second port is opened, so the average sound pressure level (SPL: sound pressure level) of the leakage sound (530, 540) can be about -20[dB] to about 40[dB]. Therefore, the first port hole (232) of the second port is opened, so the average sound pressure level (530, 540) of the leakage sound can be relatively reduced. Sound leaking from the first port (260) (e.g., main port) and sound leaking from the first port hole (232) of the second port (230) may cancel each other out, thereby forming a null point where the magnitude of the leak sound is rapidly attenuated.

[0139] According to one embodiment, the second dynamic vent (220) operates in a first state (open state) and the first dynamic vent (210) operates in a second state (close state) so that the second port hole (234) can be opened. At this time, the first port hole (232) can be closed. In this case, the second port hole (234) of the second port (230) is opened so that the average sound pressure level (550, 560) of the leakage sound (SPL: sound pressure level) can be -20[dB] to 40[dB]. Therefore, the second port hole (234) of the second port (230) is opened so that the average sound pressure level (550, 550) of the leakage sound can be relatively reduced. Sound leaking from the first port (260) (e.g., main port) and sound leaking from the second port hole (234) of the second port (230) may cancel each other out, thereby forming a null point where the magnitude of the leak sound is rapidly attenuated.

[0140] According to one embodiment, by comparing FIG. 5b and FIG. 5c, it can be seen that the direction of the null point (an area where the sound pressure drops rapidly) formed when only the first port hole (232) is opened is different from when only the second port hole (234) is opened. Using this characteristic, the processor (120) can select a combination of opening and closing of a plurality of dynamic vent sections (210, 220) or adjust the opening ratio so that a null point is formed that matches the position (or direction or a combination thereof) of another person detected by the sensor (280).

[0141] In this way, the magnitude of the sound leaking from the wearable electronic device is reduced at the location where the magnitude of the leak sound rapidly attenuates (null point), so the sound heard by other people outside can be reduced.

[0142] FIGS. 6a and 6b are drawings illustrating the operation of a dynamic vent portion of a wearable electronic device according to one embodiment of the present disclosure to open or close a port hole.

[0143] Referring to FIGS. 2a, FIGS. 6a and FIGS. 6b, a speaker module (600) of a wearable electronic device (106) (e.g., speaker module (200) of FIG. 2b) may include a housing (670) (e.g., an outer case), at least one dynamic vent portion (610, 620), a speaker portion (650) (e.g., a speaker and a speaker circuit), a first port (660) (e.g., a main port), and / or a second port (230) (e.g., a sub-port).

[0144] For example, the speaker module (600) can be worn on the user's (201) ear (202) (e.g., placed close to it) to output sound to the user's (210) ear (202).

[0145] According to one embodiment, the first port (660) may be formed so that sound output from the speaker unit (650) is output in the direction of the user's ear (202). For example, the first port (660) may be positioned on the front of the speaker unit (650) (e.g., in a direction close to the user's eardrum).

[0146] According to one embodiment, the second port (230) is formed such that sound output from the speaker part (650) is output to the outside of the speaker module (600), and the first port hole (630, 2 nd port1) and the second porthole (640, 2 nd It may include port2).

[0147] For example, the first port hole (630) and the second port hole (640) of the second port may be positioned on the rear of the speaker part (650) (e.g., opposite the direction of the user's eardrum).

[0148] According to one embodiment, as illustrated in FIG. 6a, the speaker module (600) may include a first dynamic vent (610) that controls the degree to which the first port hole (630) of the second port (230) is opened or closed. For example, a processor (e.g., the processor (120) in FIG. 2b) may control the degree (%) to which the first dynamic vent (610) is opened (or closed) to configure a location (null point) where leaked sound is canceled out, based on the location, direction, and / or distance of a person in the vicinity.

[0149] According to one embodiment, the speaker module (600) may include a second dynamic vent (620) that controls the degree to which the second port hole (640) of the second port (230) is opened or closed. For example, the processor (120) may control the degree (%) to which the second dynamic vent (620) is opened (or closed) to form a null point where the leaking sound is canceled out, based on the location, direction, and / or distance of a person nearby.

[0150] For example, sound output from the speaker unit (650) can be output towards the user's ear (202) through the first port (660). The sound output through the first port (660) may leak out, but when the first dynamic vent unit (610) operates and the first port hole (630) is opened, sound with the inverse phase of the sound output through the first port (660) is output outward through the first port hole (630), thereby canceling out the sound output through the first port (660). Sound output through the first port (660) may leak out, but when the second dynamic vent (620) operates and the second port hole (234) is opened, sound with the inverse phase of the sound output through the first port (660) is output out through the second port hole (640), so that the sound output through the first port (660) can be canceled out.

[0151] According to one embodiment, as illustrated in FIG. 6b, the speaker module (600) may include a first dynamic vent portion (610) that opens or closes the first port hole (630) of the second port. The dynamic vent portion may not be placed in the second port hole (640) of the second port, and the second port hole (640) of the second port may be open.

[0152] For example, sound output from the speaker unit (250) can be output towards the user's ear (202) through the first port (660). Sound output through the first port (660) may leak out. When the first dynamic vent unit (610) operates and the first port hole (630) is opened, sound is output to the outside through the first port hole (630), and the sound output through the first port (660) can be canceled out. Additionally, since the second port hole (640) is open, sound with the inverse phase of the sound output through the first port (660) can be output to the outside through the second port hole (640), and the sound output through the first port (660) can be canceled out.

[0153] FIGS. 7a to 7c are drawings showing an acoustic mesh (or waterproof member) disposed inside a speaker module of a wearable electronic device according to one embodiment of the present disclosure.

[0154] Referring to FIGS. 2a and FIGS. 7a through 7c, a speaker module (700) (e.g., speaker module (200) of FIG. 2b) of a wearable electronic device (106) may include a housing (770) (e.g., an outer case), a plurality of dynamic vent sections (710, 720), a speaker section (750) (e.g., a speaker and a speaker circuit), a first port (760) (e.g., a main port), and a second port (230) (e.g., a sub-port).

[0155] For example, the speaker module (700) can be worn on the user's (201) ear (202) (e.g., placed close to it) to output sound to the user's (210) ear (202).

[0156] According to one embodiment, the first port (760) may be formed so that sound output from the speaker unit (750) is output in the direction of the user's ear (202). For example, the first port (760) may be positioned on the front of the speaker unit (750) (e.g., in a direction close to the user's eardrum).

[0157] According to one embodiment, the second port (230) is formed such that sound output from the speaker part (750) is output to the outside of the speaker module (700) through a first port hole (730, 2 nd port1) and the second porthole (740, 2 nd It may include port2).

[0158] For example, the first port hole (730) and the second port hole (740) of the second port (230) may be positioned on the rear of the speaker part (650) (e.g., opposite the direction of the user's eardrum).

[0159] According to one embodiment, a plurality of dynamic vent sections (710, 720) may include a first dynamic vent section (710) that opens or closes a first port hole (730). For example, a processor (e.g., processor (120) of FIG. 2b) may control the degree (%) to which the first dynamic vent section (710) is opened (or closed) to form a location (null point) where leaked sound is canceled out, based on the location, direction, and / or distance of a person nearby.

[0160] According to one embodiment, a plurality of dynamic vent sections (710, 720) may include a second dynamic vent section (720) that opens or closes a second port hole (740). For example, the processor (120) may control the degree (%) of opening (or closing) the second dynamic vent section (720) to form a null point where the leaking sound is canceled out, based on the location, direction, and / or distance of a person nearby.

[0161] According to one embodiment, FIGS. 7a and 7b show that an acoustic mesh (or waterproof member) is placed on the front (or rear) side of the dynamic vent.

[0162] According to one embodiment, a plurality of acoustic meshes (711, 721, 712, 722) may be disposed inside the housing (770).

[0163] For example, as shown in FIG. 7a, a first acoustic mesh (711) may be placed inside based on the first dynamic vent section (710). A second acoustic mesh (721) may be placed inside based on the second dynamic vent section (720).

[0164] For example, as shown in FIG. 7b, a first acoustic mesh (712) may be placed outside the first dynamic vent section (710). A second acoustic mesh (722) may be placed outside the second dynamic vent section (720).

[0165] According to one embodiment, FIG. 7c shows that an acoustic mesh (or waterproof member) is placed so as to form an acoustic passage between the first port (760) and the second port (230).

[0166] For example, as illustrated in FIG. 7c, at least one acoustic mesh (713) may be placed in at least a part of the speaker section (750). An acoustic passage may be formed between the first port (760) and the second port (230) by the acoustic mesh (713).

[0167] FIG. 8a is a drawing showing a first state (open state) of a dynamic vent portion (e.g., piezoelectric element) of a wearable electronic device according to one embodiment of the present disclosure.

[0168] FIG. 8b is a drawing showing a first state (closed state) of a dynamic vent portion (e.g., an electrostatic dynamic vent portion) of a wearable electronic device according to one embodiment of the present disclosure.

[0169] Referring to FIGS. 2a, 2b, FIGS. 8a, and FIGS. 8b, according to one embodiment, a speaker module (200) of a wearable electronic device (106) according to one embodiment of the present disclosure may include a plurality of dynamic vent portions (800) (e.g., a first dynamic vent portion (210) of FIG. 2e, or a second dynamic vent portion (220)). FIGS. 8a and 8b show one dynamic vent portion (800) among the plurality of dynamic vent portions (800).

[0170] For example, the dynamic vent section (800) may include an electrostatic type dynamic vent section in which switching of the moving electrode is performed by electrostatic force.

[0171] For example, the dynamic vent (800) can be opened when in a first state. For example, the dynamic vent (800) can be closed when in a second state.

[0172] For example, the dynamic vent portion (800) may include a first contact (810) and a second contact (820), a first electrode (830) (e.g., a fixed electrode), and a second electrode (840) (e.g., a movable electrode). The first electrode (830) (e.g., a fixed electrode) and the second electrode (840) (e.g., a movable electrode) may be positioned to face each other. Above a specific bias threshold value (e.g., a pull-in voltage), the second electrode (840) (e.g., a movable electrode) may move toward the first electrode (830) (e.g., a fixed electrode).

[0173] For example, when the switch (850) is turned off by control of the processor (120), the dynamic vent (800) operates in a first state so that the first contact (810) and the second contact (820) can be separated. When the first contact (810) and the second contact (820) are separated, the first port hole (e.g., the first port hole (232) in FIG. 2e) or the second port hole (e.g., the second port hole (234) in FIG. 2e) of the second port can be opened.

[0174] For example, when the switch (850) is turned on by control of the processor (120), the dynamic vent (800) operates in a second state so that the first contact (810) and the second contact (820) can be closed. When the first contact (810) and the second contact (820) are closed, the first port hole (232) or the second port hole (234) can be closed.

[0175] FIG. 9a is a drawing showing a first state (open state) of a dynamic vent portion (e.g., an electromagnetic dynamic vent portion) of a wearable electronic device according to one embodiment of the present disclosure.

[0176] FIG. 9b is a drawing showing a first state (closed state) of a dynamic vent portion (e.g., an electromagnetic dynamic vent portion) of a wearable electronic device according to one embodiment of the present disclosure.

[0177] Referring to FIGS. 2a, 2b, 9a, and 9b, according to one embodiment, a speaker module (200) of a wearable electronic device (106) according to one embodiment of the present disclosure may include a plurality of dynamic vent portions (900) (e.g., a first dynamic vent portion (210) of FIG. 2e, or a second dynamic vent portion (220)). FIGS. 9a and 9b show one dynamic vent portion (900) among the plurality of dynamic vent portions (900).

[0178] For example, the dynamic vent section (900) may include an electromagnetic type dynamic vent section in which switching of the moving electrode is performed by electromagnetic force.

[0179] For example, the MEMS (micro-electromechanical system) film may be formed of a ferromagnetic material sensitive to changes in a magnetic field, or coated with a ferromagnetic material. When a bias current flows through the coil and a magnetic field is generated, the moving electrode (940) can move toward the fixed electrode (930).

[0180] For example, the dynamic vent (900) can be opened when in a first state. For example, the dynamic vent (900) can be closed when in a second state.

[0181] For example, when the switch (950) is turned off by control of the processor (120), the dynamic vent (900) operates in a first state so that the first contact (910) and the second contact (920) can be separated. When the first contact (910) and the second contact (920) are separated, the first port hole (e.g., the first port hole (232) in FIG. 2e) or the second port hole (e.g., the second port hole (234) in FIG. 2e) of the second port can be opened.

[0182] For example, when the switch (950) is turned on by control of the processor (120), the dynamic vent (900) operates in a second state so that the first contact (910) and the second contact (920) can be closed. When the first contact (910) and the second contact (920) are closed, the first port hole (232) or the second port hole (234) can be closed.

[0183] FIG. 10a is a drawing showing a first state (open state) of a dynamic vent portion (e.g., a dynamic vent portion of a thermoelectric element type) of a wearable electronic device according to one embodiment of the present disclosure.

[0184] FIG. 10b is a drawing showing a first state (closed state) of a dynamic vent portion (e.g., a dynamic vent portion of a thermoelectric element type) of a wearable electronic device according to one embodiment of the present disclosure.

[0185] Referring to FIGS. 2a, 2b, FIGS. 10a, and FIGS. 10b, according to one embodiment, a speaker module (200) of a wearable electronic device (106) according to one embodiment of the present disclosure may include a plurality of dynamic vent portions (1000) (e.g., a first dynamic vent portion (210) of FIG. 2e, or a second dynamic vent portion (220)). FIGS. 10a and FIG. 10b illustrate one dynamic vent portion (1000) among the plurality of dynamic vent portions (1000).

[0186] For example, the dynamic vent section (1000) may include a dynamic vent section of the thermoelectric type in which switching occurs when mechanical thermal expansion / deformation occurs when current is applied.

[0187] For example, when current is applied to the film on the top of the movable electrode (1040), it is heated due to thermal resistance, and the material may expand due to the temperature rise. When the material expands due to the temperature rise of the movable electrode (1040), the movable electrode (1040) may move toward the fixed electrode (1030). The top of the movable electrode (1040) may be formed of a material (e.g., polycrystalline silicon) having a higher resistivity than MEMS component materials (e.g., gold, silver, copper). The dynamic vent portion (1000) may be driven with a significantly low current for the desired temperature rise and thermal deformation.

[0188] For example, the dynamic vent (1000) can be opened when in a first state. For example, the dynamic vent (1000) can be closed when in a second state.

[0189] For example, when the switch (1050) is turned off by control of the processor (120), the dynamic vent (1000) operates in a first state so that the first contact (1010) and the second contact (1020) can be separated. When the first contact (1010) and the second contact (1020) are separated, the first port hole (e.g., the first port hole (232) in FIG. 2e) or the second port hole (e.g., the second port hole (234) in FIG. 2e) of the second port (e.g., the second port (230) in FIG. 2e) can be opened.

[0190] For example, when the switch (1050) is turned on by control of the processor (120), the dynamic vent section (1000) operates in a second state so that the first contact (1010) and the second contact (1020) can be closed. When the first contact (1010) and the second contact (1020) are closed, the first port hole (232) or the second port hole (234) can be closed.

[0191] FIG. 11a is a drawing showing a first state (open state) of a dynamic vent portion (e.g., a dynamic vent portion of the ventilation hole type) of a wearable electronic device according to one embodiment of the present disclosure.

[0192] FIG. 11b is a drawing showing a first state (closed state) of a dynamic vent portion (e.g., a dynamic vent portion of the ventilation hole type) of a wearable electronic device according to one embodiment of the present disclosure.

[0193] Referring to FIGS. 2a, 2b, FIGS. 11a, and FIGS. 11b, according to one embodiment, a speaker module (200) of a wearable electronic device (106) according to one embodiment of the present disclosure may include a plurality of dynamic vent portions (1100) (e.g., a first dynamic vent portion (210) of FIG. 2e, or a second dynamic vent portion (220)). FIGS. 11a and FIG. 11b show one dynamic vent portion (1100) among the plurality of dynamic vent portions (1100).

[0194] For example, the dynamic vent section (1100) may include a dynamic vent section of the ventilation hole type, which can directly open or close the hole by causing mechanical expansion and deformation around the hole when voltage is applied to a polymer actuator (1110) of a conductive polymer material. In this case, even when closed, the hole may not be completely closed.

[0195] For example, when a voltage (DC) is applied to the polymer actuator (1110), cations inside the polymer electrolyte move to the negative electrode, and a difference in expansion and compression occurs within the space, which may cause deformation in the polymer actuator (1110).

[0196] The diameter of the hole (1120, 1130) in the shape of a donut (a shape with a hole in the center) can be varied by the pressing pressure of the polymer actuator (1110) to open or close.

[0197] For example, when the dynamic vent section (1100) is in a first state, the hole (1030) can be opened. For example, when the dynamic vent section (1100) is in a second state, the hole (1020) can be closed.

[0198] A speaker module (e.g., speaker module (200) of FIG. 2b) of a wearable electronic device (e.g., wearable electronic device (106) of FIG. 2a) according to an embodiment of the present disclosure may be applied to XR electronic devices, AR electronic devices, as well as bar-type electronic devices (e.g., bar-type smartphones), foldable-type electronic devices (e.g., foldable-type smartphones), or tablet electronic devices. For example, when the speaker module (200) of the present disclosure is applied to a bar-type electronic device or a foldable-type electronic device, at least one second port (e.g., second port (230) of FIG. 2b) and at least one variable vent (e.g., dynamic vent portions (210, 220) of FIG. 2b) may be formed on the rear portion of a housing in which a receiver for outputting call sound is disposed.
