Description

An electronic device containing an acoustic duct for a speaker

[0001] The descriptions below relate to electronic devices that include the speaker's sound duct.

[0002] Electronic devices, such as smartphones, may include speakers for outputting sound. For example, an electronic device may include a loudspeaker for outputting audio from media, and an earpiece speaker for outputting call audio so that a user can hear the voice of the person on the other end of a call by holding the device to their ear. Because these speakers differ in their intended use and required acoustic characteristics (e.g., frequency range, volume), an electronic device may typically include both an earpiece speaker and a loudspeaker.

[0003] The above information may be provided as background information to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art in connection with the present disclosure.

[0004] An electronic device according to one embodiment may include a display forming a first part of a front side (or a first surface or front surface) of the electronic device, and a first hole penetrating (i.e., being in, formed in, emerging from, or having an external mouth at) a second part of the front side (e.g., in a first direction facing the display). The second part of the front side may surround the display and / or extend from a side section of the electronic device. The electronic device may include a second hole penetrating (i.e., being in, formed in, emerging from, or having an external mouth at) the (or 'a') side section (which may also be described as an edge section) in a second direction, for example, perpendicular to the first direction. The electronic device may include a casing, a speaker (e.g., within the speaker), and a first conduit extending from the casing, within the casing, or at least partially within the casing, to the second hole so as to connect (e.g., acoustically) a diaphragm of the speaker to the second hole. That is, the first conduit is arranged to conduct sound waves generated by the speaker (in particular by the diaphragm) to the second hole (e.g., so that the sound waves generally emerge from or exit the second hole in the second direction). The electronic device may include a second conduit extending from the first conduit so as to connect (e.g., acoustically) the diaphragm to the first hole.That is, the second conduit is arranged to transmit sound waves generated by the speaker to the first hole (e.g., such that the sound waves generally escape or exit the first hole in the first direction). The second conduit may include a section inclined at an acute angle toward the first hole with respect to the second direction. The second conduit may branch off from the first conduit at an acute angle (e.g., with respect to the second direction). For example, the second conduit may at least include a section branching off from or meeting the first conduit at an acute angle with respect to the second direction, such that, for example, a side wall of the branch section meets a side wall of the first conduit at an obtuse angle.

The second housing (220) may include at least one opening (242a) that overlaps the second camera (242) when the fourth surface (222) is viewed from above. The second camera (242) may acquire an image based on receiving light from the outside of the electronic device (200) through the at least one opening (242a).

[0061] According to one embodiment, the third camera (243) may be disposed in the first housing (210). For example, the third camera (243) may be disposed inside the first housing (210) and at least a portion thereof may be visible through the first surface (211) of the first housing (210). As another example, the third camera (243) may be disposed inside the first housing (210) and at least a portion thereof may be visible through the first display area (231) of the display (230). The first display area (231) of the display (230) may include at least one opening (not shown) that overlaps the third camera (243) when the display (230) is viewed from above. The third camera (243) may acquire an image based on receiving light from the outside of the display (230) through the at least one opening.

[0062] According to one embodiment, the second camera (242) and the third camera (243) may be positioned below the display (230) (e.g., toward the inside of the first housing (210) or the inside of the second housing (220). For example, the second camera (242) and the third camera (243) may be under-display cameras (UDCs). When the second camera (242) and the third camera (243) are under-display cameras, an area of ​​the display (230) corresponding to the positions of the second camera (242) and the third camera (243), respectively, may not be an inactive area. For example, when the second camera (242) and the third camera (243) are under-display cameras, an area of ​​the display (230) corresponding to the respective positions of the second camera (242) and the third camera (243) may have a lower pixel density than the pixel density of other areas of the display (230). The inactive area of ​​the display (230) may mean an area of ​​the display (230) that does not include pixels or does not emit light to the outside of the electronic device (200). As another example, the second camera (242) and the third camera (243) may be punch-hole cameras. When the second camera (242) and the third camera (243) are punch-hole cameras, an area of ​​the display (230) corresponding to the respective positions of the second camera (242) and the third camera (243) may be an inactive area. For example, if the second camera (242) and the third camera (243) are punch hole cameras, an area of ​​the display (230) corresponding to the positions of each of the second camera (242) and the third camera (243) may include an opening that does not include pixels.

[0063] According to one embodiment, the hinge structure (250) can rotatably connect the first housing (210) and the second housing (220). The hinge structure (250) can be positioned between the first housing (210) and the second housing (220) of the electronic device (200) so that the electronic device (200) can be bent, curved, or folded. For example, the hinge structure (250) can be positioned between a portion of the first side (213) and a portion of the second side (223) that face each other. The hinge structure (250) can change the electronic device (200) into an unfolding state in which the first surface (211) of the first housing (210) and the third surface (221) of the second housing (220) are facing in substantially the same direction, or into a folding state in which the first surface (211) and the third surface (221) face each other. When the electronic device (200) is in a folding state, the first housing (210) and the second housing (220) can be folded or overlapped by facing each other.

[0064] According to one embodiment, when the electronic device (200) is in a folded state, the direction in which the first side (211) faces and the direction in which the third side (221) faces may be different from each other. For example, when the electronic device (200) is in a folded state, the direction in which the first side (211) faces and the direction in which the third side (221) faces may be opposite to each other. For another example, when the electronic device (200) is in a folded state, the direction in which the first side (211) faces and the direction in which the third side (221) faces may be inclined with respect to each other. When the direction in which the first side (211) faces is inclined with respect to the direction in which the third side (221) faces, the first housing (210) may be inclined with respect to the second housing (220).

[0065] According to one embodiment, the electronic device (200) may be foldable based on a folding axis (f). The folding axis (f) may refer to a virtual line extending through the hinge cover (251) in a direction substantially parallel to the longitudinal direction of the electronic device (200) (e.g., d1 in FIGS. 2A and 2B), but is not limited thereto. For example, the folding axis (f) may be a virtual line extending in a direction substantially perpendicular to the longitudinal direction of the electronic device (200) (e.g., d2 in FIGS. 2A and 2B). When the folding axis (f) extends in a direction substantially perpendicular to the longitudinal direction of the electronic device (200), the hinge structure (250) may extend in a direction parallel to the folding axis (f) to connect the first housing (210) and the second housing (220). The first housing (210) and the second housing (220) may be rotatable by a hinge structure (250) extending in a direction substantially perpendicular to the longitudinal direction of the electronic device (200).

[0066] According to one embodiment, the hinge structure (250) may include a hinge cover (251), a first hinge plate (252), a second hinge plate (253), and a hinge module (254).

According to one embodiment, the hinge cover (251) surrounding the hinge structure (250) may be at least partially exposed to the outside of the electronic device (200) through a space between the first housing (210) and the second housing (220) when the electronic device (200) is in a folded state. According to one embodiment, when the electronic device (200) is in an unfolded state, the hinge cover (251) may be covered by the first housing (210) and the second housing (220) and may not be exposed to the outside of the electronic device (200).

[0067] According to one embodiment, the first hinge plate (252) and the second hinge plate (253) may be coupled with the first housing (210) and the second housing (220), respectively, thereby rotatably connecting the first housing (210) and the second housing (220). For example, the first hinge plate (252) may be coupled with the first front bracket (215) of the first housing (210), and the second hinge plate (253) may be coupled with the second front bracket (227) of the second housing (220). As the first hinge plate (252) and the second hinge plate (253) are coupled to the first front bracket (215) and the second front bracket (227), respectively, the first housing (210) and the second housing (220) can be rotated according to the rotation of the first hinge plate (252) and the second hinge plate (253).

[0068] The hinge module (254) can rotate the first hinge plate (252) and the second hinge plate (253). For example, the hinge module (254) can rotate the first hinge plate (252) and the second hinge plate (253) about the folding axis (f) by including gears that are interlocked with each other and can rotate. According to one embodiment, the hinge modules (254) can be plural. For example, the plurality of hinge modules (254) can be arranged spaced apart from each other at both ends of the first hinge plate (252) and the second hinge plate (253), respectively.

The first rear bracket (216) may define a portion of an outer surface of the first housing (210). The second front bracket (227) and the second rear bracket (228) may support components of the electronic device (200). The second front bracket (227) can define a second housing (220) by being coupled with the second rear bracket (228). The second rear bracket (228) can define a portion of an outer surface of the second housing (220). For example, the display (230) can be disposed on one side of the first front bracket (215) and one side of the second front bracket (227). The first rear bracket (216) can be disposed on the other side of the first front bracket (215) opposite the one side of the first front bracket (215). The second rear bracket (228) can be disposed on the other side of the second front bracket (227) opposite the one side of the second front bracket (227). The sub display panel (235) can be placed between the second front bracket (227) and the second rear bracket (228).

[0070] In one embodiment, a portion of the first front bracket (215) may be surrounded by the first side (213), and a portion of the second front bracket (227) may be surrounded by the second side (223). For example, the first front bracket (215) may be formed integrally with the first side (213), and the second front bracket (227) may be formed integrally with the second side (223). In another example, the first front bracket (215) may be formed separately from the first side (213), and the second front bracket (227) may be formed separately from the second side (223).

The printed circuit board (261) and the printed circuit board (262) may each form an electrical connection between components within the electronic device (200). For example, components for implementing the overall function of the electronic device (200) (e.g., the processor (120) of FIG. 1) may be arranged on the printed circuit board (261), and electronic components for implementing some functions of the printed circuit board (261) may be arranged on the printed circuit board (262). For another example, components for the operation of a sub-display panel (235) placed on the fourth side (222) of a printed circuit board (262) may be placed.

[0072] According to one embodiment, the printed circuit board (261) may be disposed within the first housing (210). For example, the printed circuit board (261) may be disposed on one surface of the first front bracket (215). According to one embodiment, the printed circuit board (262) may be disposed within the second housing (220). For example, the printed circuit board (262) may be spaced apart from the printed circuit board (261) and disposed on one surface of the second front bracket (227). A flexible printed circuit board (263) may connect the printed circuit board (261) and the printed circuit board (262). For example, the flexible printed circuit board (263) may extend from the printed circuit board (261) to the printed circuit board (262).

[0073] The battery (264) is a device for supplying power to at least one component of the electronic device (200), and may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell. At least a portion of the battery (264) may be arranged substantially on the same plane as the printed circuit board (261) or the printed circuit board (262).

[0074] The antenna (265) may be configured to receive power or a signal from outside the electronic device (200).

For example, the plurality of second holes (420) may be formed as a single hole and may be referred to as a second hole.

[0084] Fig. 5a is a cross-sectional view illustrating an acoustic duct through which sound is output from a speaker module according to one embodiment. Fig. 5a is a cross-sectional view taken along line PP' of Fig. 4a. Fig. 5b is a cross-sectional view taken along line AA' of Fig. 5a. Fig. 5c is a cross-sectional view taken along line BB' of Fig. 5a.

[0085] Referring to FIGS. 5A, 5B, and 5C, the speaker module (340) may include a casing (344) and a speaker (342) within the casing (344). The casing (344) may provide a space in which the internal components of the speaker module (340) are arranged, and may form a conduit (346) for outputting sound output from the speaker (342) to the outside of the speaker module (340). The casing (344) may be accommodated in a recess (379) of a frame (370). The casing (344) may support the display (310) together with the first surface (372) of the frame (370). The speaker (342) may include a diaphragm for generating sound, and a coil and a magnet configured to vibrate the diaphragm based on an electrical signal.

[0087] An electronic device (300) according to one embodiment may include another display (310) disposed on a second surface (372B) of a support member (372). The other display (310) may be, for example, but is not limited to, the display (230) of FIG. 2A. If the other display (310) is the display (230) of FIG. 2A, a substantially transparent window may be disposed on the other display (310). Otherwise, the other display (310) may be replaced with a substantially opaque plate.

[0088] An electronic device (300) according to one embodiment may include an acoustic conduit for transmitting sound output from a speaker module (340) to the outside. For example, the electronic device (300) may include a first conduit (510) and a second conduit (520) formed by a frame (370).

[0089] In one embodiment, the first conduit (510) may extend from the speaker module (340) (e.g., conduit (346)) to the plurality of second holes (420) such that the speaker (342) (e.g., the diaphragm) is connected (e.g., acoustically) to the plurality of second holes (420). For example, the first conduit (510) may connect a conduit (346) formed in a casing (344) of the speaker module (340) to the plurality of second holes (420). For example, the first conduit (510) may include a first section (511) extending from the speaker module (340) (or the casing (344)) and a second section (512) extending from the first section (511) such that the first section (511) is connected to the plurality of second holes (420). For example, a plurality of second holes (420) may be arranged along a third direction (D3), and a second section (512) of a first conduit (510) may extend along the third direction (D3) so as to overlap the plurality of second holes (420) when viewed in the second direction (D2). The second section (512) of the first conduit (510) may include first portions (512a) spaced apart from each other based on the third direction (D3) and second portions (512b) between the first portions (512a). Each of the first portions (512a) may be directly connected to each of the plurality of second holes (420). For example, the first portions (512a) may be directly connected to each of the second holes (422, 423). The second portions (512b) may be closed by the frame (370) with respect to the second direction (D2). For example, one side of the second portions (512b) may be closed by the side member (374) (or the side portion (406)), and the other side may be closed by the support member (372). The first section (511) of the first conduit (510) may connect the conduit (346) of the speaker module (340) to the second section (512). The second section (512) of the first conduit (510) may connect the first section (511) to a plurality of second holes (420).

[0090] In one embodiment, the second section (512) of the first conduit (510) may include a diagonal shape. For example, the second section (512) of the first conduit (510) may include a portion that is inclined at an acute angle toward the first hole (410) with respect to the second direction (D2). For example, each of the second portions (512b) of the first conduit (510) may be inclined at an acute angle toward the first hole (410) with respect to the second direction (D2).

[0091] In one embodiment, a second conduit (520) may branch from the first conduit (510). The second conduit (520) may extend from the first conduit (510) to connect the speaker (342) (e.g., the diaphragm) to the first hole (410). The second conduit (520) may extend from a first opening (521) (which may also be described as a mouth, an inlet, a first cross section, a connection, or a junction) connected to a second section (512) of the first conduit (510) to a second opening (522) (which may also be described as an outlet, an outlet, or a second cross section) formed on (or within) a first surface (372A) of the frame (370). Additionally, the second conduit (520) may extend in a third direction (D3) to be connected to the first portions (512a) and the second portions (512b) of the first conduit (510). For example, the second conduit (520) may extend in the third direction (D3) to be connected above (e.g., in the first direction (D1)) the first portions (512a) and the second portions (512b). The second conduit (520) may be connected to the second section (512) of the first conduit (510). The second conduit (520) may connect the second section (512) of the first conduit (510) to the first hole (410). The second conduit (520) may extend from the second section (512) of the first conduit (510) to the first hole (410).

[0092] In one embodiment, the second conduit (520) may include a diagonal shape. For example, the second conduit (520) may include a section inclined at an acute angle toward the first hole (410) with respect to the second direction (D2). For example, based on a cross-section cut in the second direction (D2), a virtual line segment connecting the center of the first opening (521) and the center of the second opening (522) may be defined. The virtual line segment may be inclined at an acute angle toward the first hole (410) with respect to the second direction (D2). Based on the second direction (D2), a point on the edge of the first opening (521) that is farthest from the side member (374) may be located further from the side member (374) than a point on the edge of the second opening (522) that is farthest from the side member (374). Based on the cross-section cut in the second direction (D2), the area of ​​the first opening (521) may be larger than the area of ​​the second opening (522), but is not limited thereto. Accordingly, the second conduit may be tapered, which may be tapered (at least one dimension and / or cross-sectional area reduced) from the first opening (521) to the second opening (522) and / or the first hole (410). Additionally, a side wall (defining the right edge of the first opening (521) in FIG. 5B) of the second conduit (520) (provided by the surface of the frame (370)) may meet an obtuse angle with a side wall (horizontal, downward facing in FIG. 5B) of the first conduit such that the conceptual center line or center path (or sound path) of the second conduit is inclined at an acute angle with respect to the second direction and / or the conceptual center line or center path (or sound path) of the first conduit. By using a second conduit that branches off from the first conduit at an acute angle and tapers toward the first hole (i.e., widens from the first hole toward the interface, connection, or junction with the first conduit), the acoustic output of the first hole may be increased.

[0093] In one embodiment, the support member (372) may include a first side (372A) for supporting the display (310) and a second side (372B) opposite to the first side (372A) for supporting another display (310). The support member (372) may include a portion (3721) that partially forms the second conduit (520) and supports the display (310). The portion (3721) may be positioned between the recess (379) and the second conduit (520). The portion (3721), together with a speaker module (340) accommodated in the recess (379), may support the display (310).

[0094] An electronic device (300) according to one embodiment may include an acoustic membrane (550) that closes one side of a first conduit (510). For example, the acoustic membrane (550) may close a section of the first conduit (510) that is open in a direction opposite to the first direction (D1). Through the open section of the first conduit (510), a tool for processing the frame (370) to form a second conduit (520) may enter.

[0095] In one embodiment, the sealing member (360) may be disposed between the speaker module (340) and the support member (372). For example, the sealing member (360) may be disposed between the casing (344) and the support member (372). The sealing member (360) may be disposed between the conduit (346) formed by the casing (344) and the first conduit (510). The sealing member (360) may be inclined toward the display (310) in the second direction (D2). The sealing member (360) may cover the conduit (346) of the speaker module (340), thereby preventing foreign substances (e.g., dust) from entering the speaker module (340). In addition, the sealing member (360) may prevent sound from leaking between the speaker module (340) and the support member (372). The sealing member (360) may include a rubber to prevent sound leakage and a mesh-shaped membrane to prevent foreign substances from entering.

[0096] In one embodiment, an outlet of a conduit (346) connected to a sealing member (360) and a first conduit (510) may be formed on one side of the casing (344). The one side of the casing (344) may support the sealing member (360). The one side of the casing (344) may be inclined in substantially the same direction as an inclined section of the second conduit (520). For example, the one side of the casing (344) may be inclined at an acute angle toward the display (310) (or the first hole (410)) with respect to the second direction (D2).

[0097] In one embodiment, the sealing member (360) may be disposed between one surface of the casing (344) and one surface of the frame (370). The one surface of the frame (370) may support the sealing member (360). An inlet of a first conduit (510) connected to the sealing member (360) may be formed on the one surface of the frame (370). The one surface of the frame (370) may be inclined in substantially the same direction as the inclined section of the second conduit (520). For example, the one surface of the frame (370) may be inclined at an acute angle toward the display (310) (or the first hole (410)) with respect to the second direction (D2).

[0098] Fig. 6 is a graph showing a sound pressure level. The graphs (610, 615) of Fig. 6 show a sound pressure level radiated through a first hole (410), and the graphs (620, 625) show a sound pressure level radiated through a plurality of second holes (420). The graphs (610, 620) show a sound pressure level of an electronic device having a diagonal sound conduit according to an embodiment, and the graphs (615, 625) show a sound pressure level of an electronic device not including a diagonal sound conduit according to a comparative embodiment. Referring to Fig. 6, as the electronic device (300) according to an embodiment includes a diagonal sound conduit, the sound pressure level radiated in a first direction (D1) through the first hole (410) may be improved.

[0099] Typically, electronic devices may include both loudspeakers and earpiece speakers, which have different characteristics and uses. However, this wastes space in the device. If an electronic device includes only one of the loudspeakers and earpiece speakers, it may be difficult to secure the required acoustic performance. This is because users typically hold the device up to their ears during calls, whereas they do not do so during media playback, requiring different directions for sound output. Since the acoustic energy output from the speaker module (340) is conserved, closing some of the second holes (420) in the second direction (D2) will degrade the acoustic performance during multimedia playback. To prevent this, increasing the number of second holes (420) may increase the sound leak during calls. In other words, it may be difficult to apply the above-described method to improve the sound output in the first direction (D1). In order to further transmit the acoustic energy output from the speaker module (340) in the first direction (D1), the volume of the second conduit (520) connected to the first hole (410) can be increased. For example, the width of the second opening (522) of the second conduit (520) can be increased by reducing the thickness of the portion (3721) of the support member (372). However, it may be difficult to reduce the thickness of the portion (3721) of the support member (372) in order to stably support the display (310).

[0100] The electronic device (300) according to one embodiment may not include an earpiece speaker independent of the speaker module (340). The electronic device (300) according to one embodiment can increase sound (e.g., a voice signal) output in a first direction (D1) and reduce sound (e.g., a media playback sound) output in a second direction (D2) through the first conduit (510) and the second conduit (520) having a diagonal shape, as described above. For example, referring to FIG. 5B, by forming the diameter (L) of the first opening (521) larger than the first opening (521) so that the second conduit (520) has a diagonal shape, the sound pressure radiated in the first direction (D1) can be improved. Also, referring to FIG. 5c, the sound pipe of the electronic device (300) may include a first area (A1) formed by a second section (512) of a first pipe (510), and a second area (A2) formed by a second pipe (520). The section between the first area (A1) and the second area (A2) may be formed by a diagonal pipe (C1). Referring to FIGS. 5b and 5c, sound output from the speaker module (340) may be transmitted to the first pipe (510) and the second pipe (520) of FIG. 5b. Sound transmitted to the first pipe (510) and the second pipe (520) of FIG. 5b may be transmitted to the first section (511) and the second section (512) of FIG. 5c along the third direction (D3). The first region (A1) has a larger area than the second region (A2), thereby increasing the sound pressure transmitted along the third direction (D3). This increased sound pressure is radiated through the diagonal conduit (C1) and the first region (A1), thereby improving the sound pressure in the first direction (D1). As described above, by appropriately controlling the sound balance, the required sound performance can be secured.In addition, since the part (3721) for supporting the display (310) is not reduced in order to increase the size of the second conduit (520), stable support of the display (310) can be achieved while securing acoustic performance.

[0101] FIG. 7A is a diagram showing an acoustic branching space of an electronic device according to an embodiment. FIG. 7B and FIG. 7C are diagrams showing a direction in which sound branches in an acoustic branching space of an electronic device according to an embodiment. FIG. 7D is a diagram showing an area radiated in a second direction (D2) in an acoustic branching space according to an embodiment. FIG. 7E is a diagram showing an area radiated in a first direction (D1) in an acoustic branching space according to an embodiment. FIG. 8 is a graph showing a sound pressure level in each direction according to an area ratio of an acoustic branching space according to an embodiment.

[0102] Referring to FIGS. 7A, 7B, and 7C, an electronic device (300) according to an embodiment may include an acoustic branching space (700). The acoustic branching space (700) may be connected to a conduit (346) of a speaker module (340) to branch sound output from the speaker module (340). For example, sound output from the speaker module (340) may be branched in a first direction (D1), a second direction (D2), and a third direction (D3) in the acoustic branching space (700).

[0103] In one embodiment, the ratio of sound branching in each direction may vary depending on the shape of the sound branching space (700). For example, referring to FIG. 7d, the plurality of second holes (420) may include at least one hole (421) that overlaps the first section (511) of the first conduit (510) with respect to the second direction (D2). The sound pressure radiated in the second direction (D2) may vary depending on the area (S1) of the at least one hole (421). The area (S1) may be an area along the second direction (D2) (e.g., an area when viewed in the second direction (D2)). Referring to FIG. 7e, the second section (512) of the first conduit (510) may include a portion (712) that overlaps the first section (511) with respect to the second direction (D2) and overlaps the second conduit (520) with respect to the first direction (D1). Depending on the area (S2) of the portion (712), the sound pressure radiated in the first direction (D1) may vary. The area (S2) of the portion (712) may be an area based on a plane perpendicular to the first direction (D1). In one embodiment, the area (S2) may be larger than the area (S1). In one embodiment, when at least one hole (421) is implemented as one hole, the area (S1) may mean the area of ​​the first hole that overlaps the first section (511) of the first conduit (510) with respect to the second direction (D2).

[0104] In one embodiment, the ratio of sound radiated in the first direction (D1) to sound radiated in the second direction (D2) (i.e., sound in the first direction (D1) / sound in the second direction (D2)) may vary depending on the ratio of the area (S2) in the first direction (D1) to the area (S1) in the second direction (D2) (i.e., S2 / S1). For example, referring to FIG. 8, graphs (810, 815) represent sound pressure levels radiated in the first direction (D1) through the first hole (410), and graphs (820, 825) represent sound pressure levels radiated in the second direction (D2) through the plurality of second holes (420). Graphs (810, 820) represent sound pressure levels when the ratio (S2 / S1) of the area (S2) in the first direction (D1) to the area (S1) in the second direction (D2) is relatively high, and graphs (815, 825) represent sound pressure levels when the ratio (S2 / S1) of the area (S2) in the first direction (D1) to the area (S1) in the second direction (D2) is relatively low. As illustrated in Fig. 8, by making the area (S2) in the first direction (D1) larger than the area (S1) in the second direction (D2), the sound radiated in the first direction (D1) can be improved and the sound radiated in the second direction (D2) can be reduced.

[0105] Figures 9a, 9b, and 9c illustrate various shapes of a plurality of second holes according to one embodiment. Figure 10 is a graph showing negative pressure as the inner cross-sectional area of ​​a plurality of second holes decreases according to one embodiment.

[0106] Referring to FIGS. 9A, 9B, and 9C, in one embodiment, the plurality of second holes (420) may include at least one of a first acoustic hole (921), a second acoustic hole (922), and a third acoustic hole (923).

[0107] Referring to FIG. 9A, the first sound hole (921) may extend from a first opening (921a) formed on an outer surface (320C) of a side member (374) forming the side portion (406) to a second opening (921b) formed on an inner surface (374C) of the side member (374). The first sound hole (921) may include a first section (9211) extending from the first opening (921a) and a second section (9212) connecting the first section (9211) to the second opening (921b). The diameter (or cross-sectional area) of the second section (9212) may be formed smaller than that of the first section (9211). The diameter (or cross-sectional area) of the second opening (921b) may be formed smaller than that of the first opening (921a). Accordingly, the first acoustic hole (921) may be tapered. It may taper inwardly from its first opening (or outer opening) to its second opening (or inner opening). In this example, some of this gradual tapering is gradual (or continuous) (see the initially sloped sidewall portions at the outer end of the hole (921)) and some is stepped (or discontinuous) (see the step in the cross-section near the middle portion of the hole (921), i.e., at the junction or interface between the first section (9211) and the second section (212)).

[0108] Referring to FIG. 9b, the second sound hole (922) may extend from a first opening (922a) formed on an outer surface (320C) of a side member (374) forming the side portion (406) to a second opening (922b) formed on an inner surface (374C) of the side member (374). The second sound hole (922) may include a first section (9221) extending from the first opening (922a), a second section (9222) connecting the first section (9221) to a third section (9223), and a third section (9223) connected to the second opening (922b). The diameter (or cross-sectional area) of the third section (9223) may be formed to be smaller than that of the first section (9221). The second section (9222) may be formed so that its diameter (or cross-sectional area) decreases as it extends from the first section (9221) to the third section (9223). The diameter (or cross-sectional area) of the second opening (922b) may be formed smaller than that of the first opening (922a). Again, the second acoustic hole is tapered, gradually narrowing from the first opening (922a) to the second opening (922b). The central portion of this tapering is gradual (continuous) with the second section (9222) sloping inward in this example. Therefore, the second section is tapered. The third section (9223) may not be tapered per se, and may have parallel side walls in at least one cross-section (as illustrated in FIG. 9b).

[0109] Referring to FIG. 9C, the third sound hole (923) may extend from a first opening (923a) formed on an outer surface (320C) of a side member (374) forming the side portion (406) to a second opening (923b) formed on an inner surface (374C) of the side member (374). The diameter (or cross-sectional area) of the second opening (923b) may be formed to be smaller than that of the first opening (923a). For example, the third sound hole (923) may be formed so that the diameter (or cross-sectional area) gradually decreases as it extends from the first opening (923a) to the second opening (923b). The inner circumferential surface (923c) of the third sound hole (923) may extend without a step from the periphery of the first opening (923a) to the periphery of the second opening (923b). Again, the third acoustic hole can therefore be tapered.

[0110] As described above, the structure in which the cross-sectional area decreases from the outside to the inside can reduce the sound pressure radiated through the first sound hole (921), the second sound hole (922), and the third sound hole (923). Accordingly, the sound pressure radiated through the first hole (410) in a direction different from the first sound hole (921), the second sound hole (922), and the third sound hole (923) can be improved. For example, referring to FIG. 10, graphs (1010, 1015) represent sound pressure levels radiated through the first hole (410), and graphs (1020, 1025) represent sound pressure levels radiated through the plurality of second holes (420). Graphs (1010, 1020) represent sound pressure levels when the inner cross-sectional areas of the plurality of second holes (420) are reduced according to one embodiment, and graphs (1015, 1025) represent sound pressure levels when the cross-sectional areas of the plurality of second holes (420) are constant. As illustrated in FIG. 10, as the inner cross-sectional areas of the plurality of second holes (420) are reduced, the sound pressure in the first direction (D1) through the first hole (410) may increase, and the sound pressure in the second direction (D2) through the plurality of second holes (420) may decrease.

[0111] Fig. 11 is a diagram showing an electronic device to which an acoustic element is applied according to one embodiment. Fig. 12 is a graph showing sound pressure according to the application of an acoustic element.

[0112] Referring to FIG. 11, an electronic device (300) according to an embodiment may further include an acoustic member (1150). The plurality of second holes (420) according to an embodiment may include at least one hole (1120) extending from a first opening (1120a) formed on an outer surface (320C) of a side member (374) to a second opening (1120b) formed on an inner surface (374C) of the side member (374). The acoustic member (1150) may be disposed on the inner surface (374C) of the side member (374) so ​​as to cover the at least one hole (1120). The acoustic member (1150) may cover the second opening (1120b) of the at least one hole (1120). The acoustic member (1150) may be formed of a material having a specified acoustic impedance to prevent sound leakage. For example, the acoustic member (1150) may be formed of a material having an acoustic impedance of about 1500 rayl (or pas / m3) or more, but is not limited thereto. The acoustic member (1150) may be applied to the first acoustic hole (921) of FIG. 9A, the second acoustic hole (922) of FIG. 9B, and the third acoustic hole (923) of FIG. 9C.

[0113] In one embodiment, as the acoustic member (1150) is applied, the sound pressure in the second direction (D2) may decrease, and the sound pressure in the first direction (D1) may increase. Accordingly, the difference between the sound pressure in the first direction (D1) and the sound pressure in the second direction (D2) may be reduced. For example, referring to FIG. 12, graphs (1210, 1215) represent sound pressure levels radiated in the first direction (D1) through the first hole (410), and graphs (1220, 1225) represent sound pressure levels radiated in the second direction (D2) through the plurality of second holes (420). Graphs (1210, 1220) represent sound pressure levels when an acoustic member (1150) is applied according to an embodiment, and graphs (1215, 1225) represent sound pressure levels when an acoustic member (1150) is not applied. As illustrated in FIG. 12, when an acoustic member (1150) according to an embodiment is applied, the sound pressure in the second direction (D2) may decrease and the sound pressure in the first direction (D1) may increase. Accordingly, the difference between the sound pressure in the first direction (D1) and the sound pressure in the second direction (D2) may decrease.

[0114] An electronic device (e.g., an electronic device (300) of FIG. 3) according to one embodiment comprises: a display (e.g., a display (310) of FIG. 3) forming a first part (e.g., a first part (402) of FIG. 4b) of a front part (e.g., a front part (401) of FIG. 4b) of the electronic device; a second part (e.g., a second part (404) of FIG. 4b) of the front part that surrounds the display and extends from a side part (e.g., a side part (406) of FIG. 4b) of the electronic device; a first hole (e.g., a first hole (410) of FIG. 4a) penetrating in a first direction (e.g., a first direction (D1) of FIG. 4a) toward the display; a second hole (e.g., a plurality of second holes (420) of FIG. 4b) penetrating in a second direction (e.g., a second direction (D2) of FIG. 4a) perpendicular to the first direction) the side part; and a casing (e.g., a casing). The casing (344) of Fig. 5b), a speaker within the casing (e.g., the speaker (342) of Fig. 5b), a first conduit (e.g., the first conduit (510) of Fig. 5b) extending from the casing to the second hole so that a diaphragm of the speaker is connected to the second hole, and a second conduit (e.g., the second conduit (520) of Fig. 5b) extending from the first conduit to connect the diaphragm to the first hole. The second conduit may include a section inclined at an acute angle toward the first hole with respect to the second direction. Through this, the sound pressure level radiated in the first direction through the first hole can be improved. In addition, by controlling the balance between the sound radiated in the first direction and the sound radiated in the second direction, the sound performance can be improved.

[0115] In one embodiment, the first conduit may include a first section extending from the casing (e.g., the first section (511) of FIG. 5B) and a second section extending from the first section such that the first section is connected to the second hole (e.g., the second section (512) of FIG. 5B). The second conduit may be connected to the second section of the first conduit. The second section of the first conduit may include a portion inclined at an acute angle toward the first hole with respect to the second direction.

[0116] In one embodiment, the second hole may be formed of a plurality of second holes (i.e., the second hole may be one of the plurality of second holes, and the second hole may be at least one second hole). The plurality of second holes may be arranged along a third direction perpendicular to the first direction and the second direction (e.g., the third direction (D3) of FIG. 4A). The second section of the first conduit may extend along the third direction so as to overlap the plurality of second holes when viewed in the second direction.

[0117] In one embodiment, the second section of the first conduit may include first portions spaced apart from each other with respect to the third direction (e.g., first portions (512a) of FIG. 5A) and second portions (e.g., second portions (512b) of FIG. 5A) between the first portions. Each of the first portions may be directly connected to each of the plurality of second holes (or a respective one of the plurality of second holes). The second portions may be closed by the side portion with respect to the second direction.

[0118] In one embodiment, the second portions may be angled at an acute angle toward the first hole with respect to the second direction.

[0119] In one embodiment, the second conduit may be connected above the first portions and the second portions of the first conduit by extending in the third direction.

[0120] In one embodiment, the second hole may be formed of a plurality of second holes. At least one hole among the plurality of second holes (e.g., at least one hole (421) of FIG. 7d) may overlap the first section of the first conduit with respect to the second direction. The second section of the first conduit may include a branch space (e.g., an acoustic branch space (700) of FIG. 7a) that overlaps the first section with respect to the second direction and overlaps the second conduit with respect to the first direction. An area of ​​the branch space (700) cut along a plane perpendicular to the first direction (e.g., an area (S2) of FIG. 7e) may be larger than an area of ​​the first at least one hole (e.g., an area (S1) of FIG. 7d). Through this, acoustic performance may be improved by controlling a balance between sound radiated in the first direction and sound radiated in the second direction.

[0121] In one embodiment, at least one of the second holes (e.g., the first sound hole (921) of FIG. 9A, or the second hole (922) of FIG. 9B, the third sound hole (923) of FIG. 9C, or at least one hole (1020) of FIG. 11) is formed from a first opening (e.g., the first opening (921a) of FIG. 9A, the first opening (922a) of FIG. 9B, the first opening (923a) of FIG. 9C, or the first opening (1120a) of FIG. 11) formed on an outer surface of the side portion (e.g., the outer surface (320C) of FIG. 11)) to a second opening (e.g., the second opening (921b) of FIG. 9A, the second opening (922b) of FIG. 9B, the second opening (923a) of FIG. 9C) formed on an inner surface of the side portion (e.g., the inner surface (374C) of FIG. 11)) The electronic device may include an acoustic member (e.g., an acoustic member (1150) of FIG. 11) disposed on the inner surface of the side portion to cover the second opening. The acoustic member may provide resistance to sound radiated in the second direction, thereby improving the sound pressure level radiated in the first direction.

[0122] In one embodiment, the cross-sectional area of ​​the second opening may be smaller than the cross-sectional area of ​​the first opening. Accordingly, by reducing the sound pressure radiated in the second direction, the sound pressure radiated in the first direction can be improved.

[0123] In one embodiment, the at least one hole may include a first section connected to the first opening and having a first cross-sectional area (e.g., the first section (9211) of FIG. 9A or the first section (9221) of FIG. 9B), and a second section connecting the first section of the at least one hole to the second opening and having a second cross-sectional area (e.g., the second section (9212) of FIG. 9A or the third section (9223) of FIG. 9B). The second cross-sectional area may be smaller than the first cross-sectional area.

[0124] In one embodiment, the at least one hole may include an inner surface (e.g., inner surface (923c) of FIG. 9c) extending from a perimeter of the first opening to a perimeter of the second opening. The inner surface may extend from the first opening to the second opening without a step.

[0125] The electronic device according to one embodiment may include a frame (e.g., frame (370) of FIG. 3) forming the second part and the side part of the front part. The first conduit and the second conduit may be formed by the frame.

[0126] In one embodiment, the frame may include a first surface (e.g., the first surface (372A) of FIG. 5B) supporting the display and a second surface (e.g., the second surface (372B) of FIG. 5B) opposite to the first surface. The second conduit may extend from a first opening (e.g., the first opening (521) of FIG. 5B) connected to the first conduit to a second opening (e.g., the second opening (522) of FIG. 5B) formed in the first surface of the frame. With respect to the second direction, the first opening and the second opening of the second conduit may include a first center point and a second center point. An imaginary line connecting the first center point and the second center point may be inclined at an acute angle toward the first hole with respect to the second direction.

[0127] In one embodiment, with respect to the second direction, the cross-sectional area of ​​the first opening of the second conduit may be larger than the cross-sectional area of ​​the second opening of the second conduit.

[0128] In one embodiment, the casing may be accommodated in a recess formed in the first surface of the frame (e.g., recess (379) in FIG. 3) to support the display together with the first surface of the frame.

[0129] In one embodiment, the frame may include a part (e.g., part (3721) of FIG. 5B) that supports the display and partially forms the second conduit. The part of the frame may be positioned between the second conduit and the recess. This allows for an improvement in the sound pressure radiated in the first direction, even if the part is not reduced, and for the display to be stably supported by the part.

[0130] In one embodiment, a conduit (e.g., conduit (346) of FIG. 5b) that transmits sound output from the speaker to the first conduit may be formed in the casing. The electronic device may include a sealing member (e.g., sealing member (360) of FIG. 5b) disposed between the conduit of the casing and the first conduit.

[0131] In one embodiment, the sealing member may be inclined at an acute angle toward the display with respect to the second direction.

[0132] In one embodiment, an outlet of the conduit (346) connected to the sealing member may be formed on one side of the casing. The one side of the casing may support the sealing member and may be inclined in the same direction as the inclined section of the second conduit.

[0133] According to one embodiment, the electronic device may include a frame. The sealing member may be disposed between one surface of the casing and one surface of the frame. The one surface of the frame may support the sealing member. An inlet of a first conduit connected to the sealing member may be formed on the one surface of the frame. The one surface of the frame may be inclined in the same direction as the inclined section of the second conduit.

[0134] According to one embodiment, the electronic device may include a first housing including the display (e.g., the first housing (210) of FIG. 2A), a second housing (e.g., the second housing (220) of FIG. 2A), and a hinge structure (e.g., the hinge structure (250) of FIG. 2B) rotatably connecting the first housing to the second housing. The front portion may be a front portion of the second housing. The side portion may be a side portion of the second housing. The first hole and the second hole may be formed in the second housing. The casing may be disposed within the second housing.

[0135] The electronic device according to one embodiment may include another display (e.g., another display (380) of FIG. 5B) disposed on the rear surface of the first housing and the rear surface of the second housing across the hinge structure.

[0136] In one embodiment, the other display may include a flexible display.

[0137] In one embodiment, the display may include a display panel (e.g., display panel (311) of FIG. 5B) and a cover (e.g., cover (312) of FIG. 5B) on the display panel. The first hole may be partially formed by the cover.

[0138] In one embodiment, the first hole and the second hole may be located on one side of the display when viewed in the first direction.

[0139] According to one embodiment, the electronic device may not include an earpiece speaker independent of the speaker. Accordingly, mounting space can be saved.

[0142] The embodiments of this document and the terminology used herein are not intended to limit the technical features described in this document to specific embodiments, but should be understood to include various modifications, equivalents, or substitutes of the embodiments. In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more of the items, unless the context clearly indicates otherwise. In this document, each of the phrases "A or B", "at least one of A and B", "at least one of A or B", "A, B, or C", "at least one of A, B, and C", and "at least one of A, B, or C" can include any one of the items listed together in the corresponding phrase among the phrases, or all possible combinations thereof. Terms such as "first," "second," or "first" or "second" may be used merely to distinguish one component from another, and do not limit the components in any other respect (e.g., importance or order). When a component (e.g., a first component) is referred to as "coupled" or "connected" to another component (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0143] The term "module" used in the embodiments of this document may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0144] One embodiment of the present document may be implemented as software (e.g., a program (140)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device (101)). For example, a processor (e.g., a processor (120)) of the machine (e.g., an electronic device (101)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

[0145] According to one embodiment, the method according to one embodiment disclosed in the present document may be provided as included in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or may be distributed online (e.g., downloaded or uploaded) via an application store (e.g., Play Store™) or directly between two user devices (e.g., smart phones). In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily generated in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or an intermediary server.

[0146] According to one embodiment, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and arranged in other components. According to one embodiment, one or more components or operations of the aforementioned components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., a module or a program) may be integrated into a single component. In such a case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to one embodiment, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.
