The port hole (361a) may be formed in a direction facing the plate hole (371). The port hole (361a) will be described in detail later with reference to FIGS. 9 and 10.

[0112] According to one embodiment, the wearable electronic device (301) may include a plate (370). The plate (370) may be positioned between the housing (310) and a side (342) of the bracket (340). The plate (370) may define at least a portion of the duct (D).

For example, referring to FIG. 8, the acoustic conduit (P) may include a port hole (361a) (or the second opening (314)), a duct (D), at least a portion of the internal space (S) of the housing (310) (e.g., the front volume (S1), the first rear volume (S2) and the second rear volume (S3) of FIG. 8), and an output conduit (O) (or the first opening (313)). The acoustic conduit (P) may mean an empty space extending from the output conduit (O) through the internal space (S) of the housing to the second opening (314). The acoustic conduit (P) may be referred to as a “conduit.” The acoustic conduit (P) may be referred to as a "bypass conduit." The acoustic conduit (P) may be referred to as a "vent hole." The acoustic conduit (P) may be referred to as a "sound path." The acoustic conduit (P) may be referred to as a "tunnel." The acoustic conduit (P) may be referred to as a "flow conduit." When the wearable electronic device (301) is mounted on a user's ear, the inside and outside of the user's ear may be connected through the acoustic conduit (P), thereby improving the sound quality.

[0120] According to one embodiment, the acoustic duct (P) may include a front volume (S1). The front volume (S1) may refer to a space on the side of the first opening (313) of the membrane (331) of the speaker (330). The front volume (S1) may be in communication with the internal space (S) and may be understood as being a part of the internal space (S).

[0121] According to one embodiment, the acoustic duct (P) may include a first rear volume (S2). The first rear volume (S2) may refer to a space on the bracket (340) side of the membrane (331) of the speaker (330). The first rear volume (S2) may be in communication with the internal space (S) and may be understood as being a part of the internal space (S).

[0122] In one embodiment, the acoustic duct (P) may include a second rear volume (S3). The second rear volume (S3) may refer to a space between a side surface of the speaker (330) and the housing (310). The second rear volume (S3) may be understood as a part of the internal space (S). The front volume (S1), the first rear volume (S2), and the second rear volume (S3) may be in communication with each other.

[0123] In one embodiment, the acoustic conduit (P) may include an output conduit (O). The output conduit (O) may be in communication with an internal space (S). For example, the output conduit (O) may be in communication with a front volume (S1).

[0124] In one embodiment, the acoustic conduit (P) may include a duct (D). The duct (D) may extend from the interior space (S) of the housing (310) toward the second opening (314). The duct (D) may be in communication with the interior space (S). For example, the duct (D) may be in communication with the second rear volume (S3). The duct (D) may be in communication with the second opening (314).

[0125] According to one embodiment, the duct (D) may be formed between the side portion (342) of the bracket (340) and the plate (370). For example, the duct (D) may be defined by a recess (R) formed in the side portion (342) of the bracket (340) and the plate (370). In this way, by forming the duct (D) using the bracket (340), which is a component of the wearable electronic device (301), the space efficiency within the housing (310) may be improved. However, the present invention is not limited thereto, and the duct (D) may also be formed using a separate pipe member.

[0126] According to one embodiment, the duct (D) can control the rear leakage sound by the speaker (330). Specifically, the rear leakage sound by the speaker (330) can flow to the outside of the second opening (314) through the duct (D). At this time, when the specific acoustic impedance of the duct (D) and / or the specific acoustic impedance between the duct (D) and the second opening (314) decreases, the sound pressure level of the rear leakage sound decreases, and when the specific acoustic impedance of the duct (D) and / or the specific acoustic impedance between the duct (D) and the second opening (314) increases, the sound pressure level of the rear leakage sound can increase. In this way, the sound pressure level of the rear leakage sound can be controlled through an appropriate design of the duct (D).

[0127] According to one embodiment, the acoustic performance of the speaker (330) can be improved through the duct (D). Specifically, the load applied to the rear of the speaker (330) through the duct (D) can be adjusted. For example, if the non-acoustic impedance of the duct (D) and / or the non-acoustic impedance between the duct (D) and the second opening (314) increases, the load applied to the speaker (330) increases, and thus the acoustic performance of the speaker (330) may deteriorate. On the other hand, if the non-acoustic impedance of the duct (D) decreases, the load applied to the speaker (330) decreases, and thus the acoustic performance of the speaker (330) may improve. In this way, the acoustic performance of a wearable electronic device can be improved through an appropriate design of the duct (D). This will be described in detail later with reference to FIGS. 14 to 19 .

FIG. 10 is an exploded perspective view of a portion of a wearable electronic device according to an embodiment of the present disclosure. FIG. 11 is an exploded perspective view of a portion of a wearable electronic device according to an embodiment of the present disclosure. FIG. 12 is a plan view of a portion of a wearable electronic device according to an embodiment of the present disclosure. FIG. 13 is a perspective view and a cross-sectional view illustrating the volume of a duct of a wearable electronic device according to an embodiment of the present disclosure.

[0129] Specifically, FIG. 9 is a cross-sectional view illustrating an enlarged area M of FIG. 7. FIG. 10 is an exploded view illustrating the configuration of the recess (R) and the second opening (314) area formed in the bracket (340). FIG. 11 is an exploded view illustrating the recess (R) to the plate (370) portion of FIG. 10. FIG. 12 is a front view illustrating the shape of the duct (D). FIG. 13 illustrates the volume of the duct (D) and a cross-section of the duct (D).

[0130] According to one embodiment, the wearable electronic device (301) may include a plate (370). The plate (370) may be positioned between the housing (310) and the side (342) of the bracket (340). For example, the plate (370) may be mounted on the side (342). For example, the plate (370) may be mounted on a mounting portion (343) formed on the side (342) of the bracket (340).

[0131] In one embodiment, the plate (370) may be coupled to the side (342). For example, the plate (370) may be coupled to a mounting portion (343) formed on the side (342) of the bracket (340). For example, the plate (370) may be attached to the side (342) via a first adhesive member (A1). However, the present invention is not limited thereto, and the plate (370) may also be coupled to the side (342) via a separate mechanical mechanism.

[0132] In one embodiment, the plate (370) may cover at least a portion of the recess (R). For example, the plate (370) may cover the remaining portion of the recess (R) except for the portion that overlaps the plate hole (371). However, alternatively, depending on the size or length of the required duct (D), there may be a portion of the recess (R) that is not covered by the plate (370) in addition to the portion that overlaps the plate hole (371).

[0133] According to one embodiment, the plate (370) may include a plate hole (371). The plate hole (371) may connect the duct (D) to the second opening (314). Depending on the size of the plate hole (371), the non-acoustic impedance between the duct (D) and the second opening (314) may be adjusted. For example, as the plate hole (371) becomes larger, the non-acoustic impedance between the duct (D) and the second opening (314) may decrease, and as the plate hole (371) becomes smaller, the non-acoustic impedance between the duct (D) and the second opening (314) may increase. For example, the area of ​​the plate hole (371) is approximately 1.4 mm. 2 It could be.

[0134] According to one embodiment, the plate hole (371) may be formed in a rectangular shape. For example, the plate hole (371) may have a shape extending in a direction (X2) intersecting the extension direction (X1) of the duct (D). Referring to FIG. 12, the plate hole (371) may have a rectangular shape extending in a direction (X2) intersecting the extension direction (X1) of the duct (D). Since the plate hole (371) is formed with a short width along the extension direction (X1) of the duct (D), the length of the duct (D) can be easily adjusted. Accordingly, by easily adjusting the length of the duct (D), the non-acoustic impedance of the duct (D) can be easily adjusted. In addition, since the plate hole (371) is formed long in the direction (X2) intersecting the extension direction (X1) of the duct (D), the plate hole (371) can be formed with a sufficient size. As the plate hole (371) is formed to a sufficient size, an appropriate acoustic impedance between the duct (D) and the second opening (314) can be set.

[0135] According to one embodiment, the plate (370) may include at least one of SUS (steel use stainless), SPCC (steel plate cold rolled commercial), PC (polycarbonate), or PET (polyethyleneterephthalate). For example, the plate (370) may include any combination of SUS, SPCC, PC, or PET. For example, the plate (370) may be composed of SUS or SPCC. In this case, sufficient rigidity of the plate (370) can be secured, thereby improving the durability of the wearable electronic device (301). Alternatively, the plate (370) may be composed of PC Sheet or PET Sheet. In this case, the manufacturing cost of the plate (370) can be reduced, which may be advantageous in terms of cost. However, the material of the plate (370) is not limited to the above-described SUS, SPCC, PC Sheet, and / or PET Sheet.

[0136] According to one embodiment, the bracket (340) may include a recess (R). The recess (R) may be formed in the side (342). The recess (R) may be formed by recessing inwardly from the outer surface of the side (342). The recess (R) may extend toward the first opening (313) in an area overlapping the second opening (314). For example, the recess (R) may extend from the area overlapping the second opening (314) to the edge of the side (342) toward the first opening (313).

[0137] According to one embodiment, the acoustic impedance of the duct (D) can be adjusted depending on the depth of the recess (R). For example, the deeper the recess (R), the larger the cross-sectional area of ​​the duct (D), thus decreasing the acoustic impedance of the duct (D), and the shallower the recess (R), the smaller the cross-sectional area of ​​the duct (D), thus increasing the acoustic impedance.

[0138] According to one embodiment, the bracket (340) may include a mounting portion (343). The mounting portion (343) may be formed on the side portion (342). The mounting portion (343) may be positioned on at least a portion of the periphery of the recess (R). For example, the mounting portion (343) may be formed to surround the remaining portion of the recess (R) except for the end portion on the side of the first opening (313). The plate (370) may be in close contact with the mounting portion (343). For example, the plate (370) may be attached to the mounting portion (343).

[0139] According to one embodiment, the mounting portion (343) may extend parallel to the plate (370). For example, if the plate (370) is flat, the mounting portion (343) may have a correspondingly flat shape. However, the present invention is not limited thereto, and if the plate (370) is curved, the mounting portion (343) may correspondingly have a correspondingly curved shape. Through this, the plate (370) can be stably coupled (or attached) to the mounting portion (343).

[0140] According to one embodiment, the outer line of the mounting portion (343) and the outer line of the plate (370) may correspond at least partially. For example, a portion of the outer line of the mounting portion (343) excluding a portion where a recess (R) is formed may correspond to the outer line of the plate (370). For example, referring to FIGS. 10 and 12 , the plate (370) may have an approximately pentagonal shape, and the mounting portion (343) may be provided with an approximately pentagonal shape corresponding thereto. Through this, the attachment position of the plate (370) may be easily guided.

[0141] According to one embodiment, the bracket (340) may include a protrusion (344). The protrusion (344) may protrude outwardly from at least a portion of an area corresponding to an edge of the plate (370). For example, referring to FIGS. 9 to 11 , the protrusion (344) may protrude from an upper edge of the mounting portion (343). However, the present invention is not limited thereto, and the protrusion (344) may protrude outwardly from any area of ​​the edge of the mounting portion (343).

[0142] According to one embodiment, the side surface of the protrusion (344) and the outline of the plate (370) may at least partially correspond. For example, referring to FIGS. 9 to 11, the upper edge of the mounting portion (343) may have a shape corresponding to the upper edge of the plate (370), and the protrusion (344) may protrude outward from the upper edge of the mounting portion (343). Through this, the shape of the side surface of the mounting portion (343) may correspond to the upper edge of the plate (370). Through this, the position of the plate (370) may be guided during the process of coupling (or attaching) the plate (370) to the mounting portion (343).

[0143] According to one embodiment, the wearable electronic device (301) may include a first adhesive member (A1). The first adhesive member (A1) may be disposed between the side portion (342) and the plate (370). For example, the first adhesive member (A1) may be disposed on a mounting portion (343) formed on the side portion (342). For example, the first adhesive member (A1) may be disposed on an inner surface of the plate (370). The first adhesive member (A1) may attach the plate (370) to the side portion (342).

[0144] According to one embodiment, the first adhesive member (A1) may include an adhesive opening (AH). The adhesive opening (AH) may be understood as a cavity portion formed by penetrating the first adhesive member (A1). The adhesive opening (AH) may have a shape corresponding to the shape of the recess (R). For example, referring to FIG. 11, the recess (R) may extend in a bent shape on the side (342), and the adhesive opening (AH) may have a corresponding bent shape. The adhesive opening (AH) may define a portion of the duct (D). At least a portion of the adhesive opening (AH) may overlap with a plate hole (371) of the plate (370).

[0145] According to one embodiment, the first adhesive member (A1) may be provided with at least one of a double-sided tape, a bond, a glue, or an adhesive. For example, the first adhesive member (A1) may be provided with a double-sided tape. When the first adhesive member (A1) is provided with a double-sided tape, the shape of the first adhesive member (A1) including the adhesive opening (AH) can be precisely defined, and a part of the first adhesive member (A1) can be prevented from being pushed into the interior of the duct (D) and affecting the size of the duct (D). In addition, when the first adhesive member (A1) is provided with a double-sided tape, even if the shape of the mounting portion (343) to which the plate (370) is attached has a three-dimensional curved shape, the application of the first adhesive member (A1) can be easy. In addition, when the first adhesive member (A1) is provided as a double-sided tape, a separate drying process can be omitted, so that the ease of assembly of the wearable electronic device (301) can be improved. In addition, when the first adhesive member (A1) is provided as a double-sided tape, the plate (370) can be easily detached, so that the ease of reassembly can also be improved. However, the present invention is not limited thereto, and the plate (370) may be attached to the side (342) by a bonding method. For example, if the thickness and / or shape of the first adhesive member (A1) can be precisely adjusted, quick drying is possible, and the material of which the plate (370) is easily detachable, the first adhesive member (A1) may be provided as a bond, glue, or adhesive.

[0146] According to one embodiment, the cross-sectional area of ​​the duct (D) can be adjusted depending on the thickness of the first adhesive member (A1), and thus the acoustic impedance of the duct (D) can be adjusted. For example, when the thickness of the first adhesive member (A1) is about 0.05T, the minimum depth (d) of the duct (D) is about 0.15T, and the cross-sectional area (s) of the duct (D) is about 0.4mm. 2For example, when the thickness of the first adhesive member (A1) is about 0.15T, the minimum depth (d) of the duct (D) is about 0.25T, and the cross-sectional area (s) of the duct (D) is about 0.55mm 2 For example, when the thickness of the first adhesive member (A1) is about 0.25T, the minimum depth (d) of the duct (D) is about 0.35T, and the cross-sectional area (s) of the duct (D) is about 0.71mm 2 It may be. In terms of reducing the acoustic impedance of the duct (D), it may be advantageous for the first adhesive member (A1) to be thick in order to increase the cross-sectional area of ​​the duct (D). However, in terms of securing the durability of the duct (D) structure, the cross-sectional area of ​​the duct (D) may be adjusted by the depth of the recess (R), and the first adhesive member (A1) may be used as an auxiliary means to secure the cross-sectional area of ​​the duct (D).

[0147] According to one embodiment, an acoustic conduit (e.g., an acoustic conduit (P) of FIGS. 7 and 8) may include a duct (D). The duct (D) may be defined by a plate (370) and a recess (R). For example, the duct (D) may be formed by the plate (370) covering a concave portion formed by the recess (R). For example, if the plate (370) is structured to be joined to the side (342) without the first adhesive member (A1), the duct (D) may be defined only by the recess (R) and the plate (370).

[0148] According to one embodiment, the duct (D) may be defined by a recess (R), a plate (370), and a first adhesive member (A1). For example, the duct (D) may be formed by the plate (370) covering a concave portion formed by the recess (R) and an adhesive opening (AH) of the first adhesive member (A1) formed in a shape corresponding to the recess (R). In this case, the cross-sectional area of ​​the duct (D) may be adjusted by the thickness of the first adhesive member (A1).

[0149] According to one embodiment, the duct (D) may be in communication with the internal space (S). For example, the end of the first opening (313) side of the duct (D) may be in communication with the internal space (S) (e.g., the second rear volume (S3) of FIG. 8).

[0150] According to one embodiment, the wearable electronic device (301) may include a mesh member (362). The mesh member (362) may be disposed on the outside of the plate (370). For example, the mesh member (362) may be disposed between the plate (370) and the ventilation port (361) (or the second opening (314)). The mesh member (362) may include a material that allows sound (or air) to pass through.

[0151] According to one embodiment, the mesh member (362) can cover the plate hole (371). The mesh member (362) can be provided with a size at least larger than the plate hole (371).

[0152] According to one embodiment, the non-acoustic impedance between the duct (D) and the external environment can be adjusted by the mesh member (362). For example, the non-acoustic impedance between the duct (D) and the second opening (314) can be adjusted depending on the number of mesh counts of the mesh member (362), the size of the opening, the opening ratio, the thickness, and the air permeability.

[0153] According to one embodiment, the non-acoustic impedance between the duct (D) and the second opening (314) can be determined by a complex combination of the characteristics of the plate hole (371) and the characteristics of the mesh member (362). The frequency response characteristics of the speaker according to the non-acoustic impedance between the duct (D) and the second opening (314) determined by the plate hole (371) and the mesh member (362) will be described in detail later with reference to FIG. 19.

[0154] In one embodiment, the mesh member (362) may be a component of the second port assembly (360). For example, the mesh member (362) may be attached to a ventilation port (361) disposed on the outside of the mesh member (362) by a second adhesive member (A2). However, the present invention is not limited thereto, and the mesh member (362) may also be coupled to the ventilation port (361) by a separate mechanical mechanism. During the assembly process of the wearable electronic device (301), before coupling the second housing (312) to the first housing (311), the mesh member (362) may be coupled (or attached) to the ventilation port (361) attached to the second housing (312).

[0155] Contrary to the above, if the desired acoustic impedance can be achieved by adjusting the size of the plate hole (371) alone, the mesh member (362) may not be provided.

[0156] According to one embodiment, the wearable electronic device (301) may include a waterproof member. The waterproof member may be disposed on the outside of the plate (370). For example, the waterproof member may be disposed between the plate (370) and the ventilation port (361) (or the second opening (314)). The waterproof member may be formed of a material that allows sound (or air) to pass through, but does not readily allow moisture to pass through.

[0157] According to one embodiment, the waterproof member and the mesh member (362) may be provided selectively. Both the waterproof member and the mesh member (362) are configured to increase the non-acoustic impedance between the duct (D) and the second opening (314). If both configurations are used, the non-acoustic impedance between the duct (D) and the second opening (314) may become excessively high. Therefore, the waterproof member and the mesh member (362) may be used selectively. For example, referring to FIGS. 9 and 10, if the waterproof member is provided instead of the mesh member (362), the waterproof member may be arranged at the position of the mesh member (362). The specific arrangement relationship and shape of the waterproof member may be the same as or similar to the specific arrangement relationship and shape of the mesh member (362). However, the present invention is not limited thereto, and even if the mesh member (362) and the waterproof member are provided at the same time, if the non-acoustic impedance between the duct (D) and the second opening (314) can be designed to an appropriate value, the mesh member (362) and the waterproof member may be provided at the same time. For example, when the waterproof member and the mesh member (362) are provided at the same time, the waterproof member may be placed on the inside and / or outside of the mesh member (362).

[0158] According to one embodiment, the wearable electronic device (301) may include a ventilation port (361). The ventilation port (361) may be positioned on the outside of the mesh member (362). For example, the ventilation port (361) may be positioned between the mesh member (362) and the second housing (312).

[0159] According to one embodiment, the ventilation port (361) may be positioned inside the second opening (314). For example, the ventilation port (361) may be inserted into the second opening (314) from inside the second housing (312).

[0160] According to one embodiment, a port hole (361a) may be formed in the ventilation port (361). The port hole (361a) may be formed by penetrating the ventilation port (361). The port hole (361a) may be formed in a direction facing the plate hole (371).

[0161] In one embodiment, the second opening (314) may be defined by a port hole (361a). For example, the port hole (361a) may be a space that at least partially overlaps the second opening (314). Specifically, since the ventilation port (361) is arranged on the inside of the second opening (314), the port hole (361a) may be arranged on the inside of the second opening (314). For example, if there is no gap between the outer surface of the ventilation port (361) and the second opening (314), the second opening (314) may be understood to be identical to the port hole (361a). Unlike the above, if the ventilation port (361a) is not structured to be inserted into the second opening (314), the second opening (314) is defined as the second housing (312), the port hole (361a) is configured as a separate space from the second opening (314), and the port hole (361a) and the second opening (314) may have a structure in which they are connected to each other.

[0162] In one embodiment, the ventilation port (361) may be a component of the second port assembly (360). For example, a mesh member (362) may be attached to the inside of the ventilation port (361) by a second adhesive member (A2), and the ventilation port (361) may be attached to the inside surface of the housing (310) (e.g., the second housing (312)) by a third adhesive member (A3). However, the present invention is not limited thereto, and the ventilation port (361) may also be coupled to the inside surface of the housing (310) (e.g., the second housing (312)) by a separate mechanical mechanism. During the assembly process of the wearable electronic device (301), before the second housing (312) is coupled to the first housing (311), the ventilation port (361) can be attached to the inside of the second housing (312) with the mesh member (362) coupled (or attached) to the inside.

[0163] According to one embodiment, the second adhesive member (A2) attaching the mesh member (362) (or waterproof member) and the ventilation port (361) and / or the third adhesive member (A3) attaching the ventilation port (361) and the second housing (312) may be advantageously thinner. As the second adhesive member (A2) and the third adhesive member (A3) become thinner, the space occupied by the second port assembly (360) inside the housing (310) may become smaller. Specifically, the space between the second housing (312) and the side portion (342) of the bracket (340) may be narrow. At this time, in order to secure the size of the duct (D), it may be desirable to design the first adhesive member (A1) and the second adhesive member (A2) as thin as possible to minimize the space occupied by the second port assembly (360) inside the housing (310). For example, the thickness of the second adhesive member (A2) and / or the third adhesive member (A3) may be 0.05T.

[0164] In one embodiment, the wearable electronic device (301) may include a compression member (380). The compression member (380) may be disposed on the outside of the plate (370). For example, the compression member (380) may be disposed between the plate (370) and the mesh member (362) (or the waterproof member). The compression member (380) may be compressed by the plate (370) and the second port assembly (360) as the second housing (312) is assembled to the first housing (311). A compression repulsive force may be generated in the compression member (380), and the compression repulsive force may press the plate (370) toward the side portion (342) of the bracket (340) and the second port assembly (360) toward the second housing (312). Through this, the plate (370) and the second port assembly (360) can be stably fixed, and displacement of the detailed components of the plate (370) and the second port assembly (360) can be prevented. In addition, through the structure in which the plate (370), the compression member (380), and the second port assembly (360) overlap each other and are pressurized, the sealing performance of the acoustic pipe (e.g., the acoustic pipe (P) of FIGS. 7 and 8) from the duct (D) to the second opening (314) can be improved.

[0165] According to one embodiment, the compression member (380) may be fixed between the plate (370) and the second port assembly (360) by being pressed by the plate (370) and the second port assembly (360). However, the present invention is not limited thereto, and the compression member (380) may be attached to the plate (370) by an adhesive means, or may be attached to the mesh member (362) (or, a waterproof member).

[0166] In one embodiment, the compression member (380) may include a flexible material. For example, the compression member (380) may include a material having elastic restoring force. For example, the compression member (380) may be formed of a sponge, foam, or rubber material. Since the compression member (380) includes a flexible material, the compression repulsive force applied to the plate (370) and the second port assembly (360) by the compression member (380) may be improved, and the sealing performance of the acoustic conduit (e.g., the acoustic conduit (P) of FIGS. 7 and 8) may be improved. The compression member (380) may be referred to as a “poron member.”

[0167] Unlike the above, when the second housing (312) is assembled to the first housing (311), if sufficient pressing force is applied between the plate (370) and the second port assembly (360), the compression member (380) may not be provided.

[0168] Figures 14 to 16 illustrate various examples of ducts of a wearable electronic device according to an embodiment of the present disclosure. Figure 17 is a graph showing the sound pressure level of rear leakage noise according to the duct length of a wearable electronic device according to an embodiment of the present disclosure. Figure 18 is a graph showing the acoustic performance of a speaker according to the duct length of a wearable electronic device according to an embodiment of the present disclosure.

[0169] Hereinafter, the length between a point corresponding to the center of the plate hole (371) of the duct (D) and an end portion of the first opening (e.g., the first opening (313) of FIG. 7) of the duct (D) may be referred to as “duct length (L).”

[0170] According to one embodiment, the duct length (L) can be formed in various ways. For example, referring to FIGS. 14 and 15, the duct length (L) of the duct (D) illustrated in FIG. 15 can be longer than the duct length (L) of the duct (D) illustrated in FIG. 14. For example, referring to FIGS. 14 and 16, the duct length (L) of the duct (D) illustrated in FIG. 16 can be shorter than the duct length (L) of the duct (D) illustrated in FIG. 14.

[0171] According to one embodiment, the acoustic performance of the speaker (330) may vary depending on the duct length (L). For example, as the duct length (L) increases, the load applied to the speaker (330) may increase. As the load applied to the speaker (330) increases, the movement of the membrane (331) of the speaker (330) may be restricted, and thus the acoustic performance may deteriorate. Conversely, as the duct length (L) decreases, the load applied to the speaker (330) may decrease. As the load applied to the speaker (330) decreases, the restriction on the movement of the membrane (331) of the speaker (330) is reduced, and thus the acoustic performance may be improved.

[0172] According to one embodiment, the size of the rear leakage sound through the second opening (e.g., the second opening (314) of FIGS. 5 to 10) may vary depending on the duct length (L). For example, as the duct length (L) increases, the path through which the rear leakage sound flows becomes longer, and thus the rear leakage sound may be reduced. On the other hand, as the duct length (L) decreases, the path through which the rear leakage sound flows becomes shorter, and thus the rear leakage sound may be increased.

[0173] In summary, as the duct length (L) increases, rear leakage noise may decrease, but the acoustic performance of the speaker (330) may deteriorate. On the other hand, as the duct length (L) decreases, rear leakage noise may increase, but the acoustic performance of the speaker (330) may improve. Therefore, in order to secure the desired acoustic performance while appropriately controlling the rear leakage noise, an appropriate design of the duct length (L) may be required.

[0174] Figure 17 is a graph showing rear leakage according to duct length (L).

[0175] Specifically, the X-axis of the graph in Fig. 17 represents frequency (Hz), and the Y-axis represents the sound pressure level (SPL) (dB) of the rear leakage sound.

[0176] Referring to Fig. 17, it can be seen that as the duct length (L) increases, the overall sound pressure level of the rear leakage sound decreases. In particular, in the practical audible frequency band of 100 Hz or higher, it can be seen that the sound pressure level of the rear leakage sound decreases when the duct length (L) is 3 mm or 5 mm, compared to when the duct length (L) is 1 mm. Specifically, it can be seen that as the duct length (L) increases in the band around 200 Hz and the band above 2000 Hz, the rear leakage sound is effectively controlled.

[0177] Figure 18 is a graph showing the frequency response (FR) characteristics of a speaker according to the duct length (L) and the target frequency response characteristics of the speaker.

[0178] Specifically, the X-axis of the graph in Fig. 18 represents frequency (Hz), and the Y-axis represents sound pressure level (SPL) (dB).

[0179] Referring to the graph in Fig. 18, it can be confirmed that the frequency response of the speaker when the duct length (L) is 2.1 mm and 3 mm is closer to the target frequency response compared to the frequency response when the duct length (L) is 4.4 mm. In other words, it can be confirmed that the shorter the duct length (L), the better the frequency response characteristics of the speaker. In particular, in the mid-low frequency range below 700 Hz, it can be confirmed that the shorter the duct length (L), the better the frequency response characteristics of the speaker.

[0180] Referring to FIGS. 17 and 18, it can be seen that a longer duct length (L) may be advantageous for controlling rear leakage noise, but a shorter duct length (L) is advantageous for improving the speaker's acoustic performance (e.g., the speaker's frequency response characteristics in the mid-low range). Therefore, it can be seen that the duct length (L) should be designed to an appropriate level in order to improve the speaker's acoustic performance while appropriately controlling rear leakage noise. For example, the duct length (L) may be 4 mm or less.

[0181] FIG. 19 is a graph showing the acoustic performance of a speaker according to the non-acoustic impedance of some components of a wearable electronic device according to one embodiment of the present disclosure.

[0182] FIG. 19 is a graph showing the frequency response characteristics of a speaker (e.g., the speaker (330) of FIGS. 5 to 7, FIGS. 9 and 10) according to the specific acoustic impedance (rayls) between a duct (e.g., the duct (D) of FIGS. 7 to 9, FIGS. 12 and 13) and a second opening (e.g., the second opening (314) of FIGS. 5 to 10), and the target frequency response characteristics of the speaker (e.g., the speaker (330) of FIGS. 5 to 7, FIGS. 9 and 10).

[0183] Specifically, the X-axis of the graph in FIG. 19 represents frequency (Hz), and the Y-axis represents sound pressure level (SPL) (dB).

[0184] The non-acoustic impedance between the duct (e.g., duct (D) of FIGS. 7 to 9, 12, and 13) and the second opening (e.g., second opening (314) of FIGS. 5 to 10) can be determined by a combination of the size of the plate hole (e.g., plate hole (371) of FIGS. 5 to 7 and 9 to 12) and the characteristics of the mesh member (e.g., mesh member (362) of FIGS. 9 and 10).

[0185] Referring to FIG. 19, it can be confirmed that the frequency response characteristics of the speaker when the non-acoustic impedance between the duct (e.g., the duct (D) of FIG. 9) and the second opening (e.g., the second opening (314) of FIGS. 5 to 10) is 38 rayls, 46 rayls, and 56 rayls is closer to the target frequency response characteristics of the speaker compared to the frequency response characteristics when the non-acoustic impedance between the duct (e.g., the duct (D) of FIGS. 7 to 9, 12, and 13) and the second opening (e.g., the second opening (314) of FIGS. 5 to 10) is 83 rayls.

[0186] In this way, in order to improve the acoustic characteristics of the speaker, it is necessary to set an appropriate non-acoustic impedance through the design of the plate hole (e.g., the plate hole (371) of FIGS. 5 to 7 and FIGS. 9 to 12) and the mesh member (e.g., the mesh member (362) of FIGS. 9 and 10). For example, the non-acoustic impedance may be about 30 rayls to about 60 rayls.

[0187] FIG. 20 is a plan view of a portion of a wearable electronic device according to an embodiment of the present disclosure. FIG. 21 is a cross-sectional view of a portion of a wearable electronic device according to an embodiment of the present disclosure. FIGS. 22 to 29 illustrate various examples of portions of a wearable electronic device according to an embodiment of the present disclosure.

[0188] Specifically, Fig. 20 illustrates a front view of the plate (470) so that the duct (D) is visible. Fig. 21 is a cross-sectional view taken along line A-A' of Fig. 20. Figs. 22 to 29 illustrate various examples of ribs (490).

[0189] The detailed configuration of a wearable electronic device (401) according to an embodiment of the present disclosure, which is not described below, may be the same as the detailed configuration of a wearable electronic device (301) according to an embodiment of the present disclosure, which is described with reference to FIGS. 1 to 18.

[0190] According to one embodiment, the bracket (440) may include a rib (490). The rib (490) may protrude from the bottom surface of the recess (R). The rib (490) may contact the plate (470). The rib (490) may be a support that supports the plate (470) with respect to the recess (R). Through the rib (490), even if an external force is applied from the outside of the plate (470), the plate (470) may be prevented from being crushed or damaged.

[0191] According to one embodiment, the rib (490) may extend in the extension direction (X1) of the duct (D). For example, as illustrated in FIG. 29, when viewed from the outside of the plate (470), the rib (490) may be formed in a rectangular shape. For example, it may be understood that the rib (490) has an elongated structure along the extension direction (X1) of the duct (D). Through the structure of the rib (490) as described above, the influence of the rib (490) on the process of sound flowing within the duct (D) can be minimized, and the error in the non-acoustic impedance value of the duct (D) set by the design of the duct (D) can be minimized.

[0192] Unlike the above, the ribs (490) may be provided in various shapes and numbers depending on the shape and / or size of the duct (D). For example, as the size of the duct (D) increases, the number of ribs (490) may increase, the cross-sectional area of ​​the ribs (490) may increase, or the cross-sectional shape of the ribs (490) may be modified in order to effectively support the plate (470). In addition, the ribs (490) may be provided in various shapes in order to adjust the specific acoustic impedance of the duct (D). For example, as the cross-sectional area of ​​the duct (D) becomes narrower due to the ribs (490), the specific acoustic impedance of the duct (D) may increase.

[0193] For example, referring to FIG. 22, the ribs (490) may be provided in two, and the cross-sections of each of the two ribs (490) may be rectangular structures extending along the extension direction (X1) of the duct (D), and the two ribs (490) may be arranged along the extension direction (X1) of the duct (D). For example, referring to FIG. 23, the ribs (490) may be provided in two, and the cross-sections of each of the two ribs (490) may be rectangular structures extending in a direction intersecting the extension direction (X1) of the duct (D), and the two ribs (490) may be arranged along the extension direction (X1) of the duct (D). For example, referring to FIGS. 24 to 26, the ribs (490) may have a structure whose cross-sectional shape is a polygon. For example, the cross-section of the ribs (490) may be approximately triangular. For example, referring to FIG. 27, the rib (490) may have a rectangular cross-sectional shape. For example, referring to FIGS. 28 and 29, the rib (490) may extend to the end of the duct (D) along the extension direction of the duct (D).

[0194] Wearable electronic devices can be worn on a user's ear. Wearable electronic devices can be connected to external electronic devices (e.g., mobile devices) via wired or wireless connections, converting electrical signals transmitted from the external electronic devices into sound and outputting them. Recently, wearable electronic devices equipped with adaptive noise cancellation (ANC) have been introduced. These wearable electronic devices are typically of the canal-type type, including ear tips. Canal-type wearable electronic devices are designed to seal the user's ear. Conventionally, to improve the feeling of fullness when these canal-type wearable electronic devices are placed on a user's ear, structures have been introduced that allow the internal and external spaces of the user's ear to communicate with each other through acoustic conduits formed within the housing and openings formed within the housing. However, wearable electronic devices according to the prior art have had limitations in controlling rear leakage noise generated through the openings in the housing due to the lack of a duct structure within the housing. Furthermore, the narrow internal space of the housing limits the provision of a duct structure.

[0195] The problem to be solved in the present disclosure is to provide a wearable electronic device capable of improving acoustic performance while effectively controlling rear leakage noise through a duct structure.

[0196] The problem to be solved in the present disclosure is to provide a wearable electronic device capable of effectively implementing a duct structure in a narrow space inside a housing of the wearable electronic device.
