CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a National Phase Entry of PCT International Application No. PCT/KR2019/004150, which was filed on Apr. 8, 2019 and claims priority to Korean Patent Application No. 10-2018-0084165, which was filed on Jul. 19, 2018 in the Korean Intellectual Property Office, the contents of which are incorporated herein by reference.

BACKGROUND

1. Field

Various embodiments relate to an electronic device, and more particularly, to an electronic device including a speaker structure.

2. Description of the Related Art

Typically, an electronic device may mean a device that performs a specific function according to a program provided therein (e.g., an electronic scheduler, a portable multimedia reproducer, a mobile communication terminal, a tablet PC, an image/sound device, a desktop/laptop PC, or a vehicle navigation system) as well as a home appliance. As the degree of integration of electronic devices has increased and super-high-speed and large-capacity wireless communication has become popular, various functions have recently come to be provided in a single electronic device, such as a mobile communication terminal. For example, various functions, such as an entertainment function (e.g., a game function), a multimedia function (e.g., a music/video reproducing function), a communication and security function for mobile banking, a schedule management function, and an e-wallet function, in addition to a communication function, have come to be integrated in a single electronic device.

Recently, body-worn electronic devices have been commercialized, and mobile communication terminals, body-worn electronic devices, or the like are in everyday use. The use environment of an electronic device may vary according to the living space or movement of an individual user, and thus the electronic device may be exposed to a risk of contamination, damage, or the like. For example, the inside of the electronic device may be contaminated by foreign matter or moisture, and a manufacturer or a user may come up with a measure to protect the electronic device from such contamination or damage. For example, a manufacturer may improve the reliability of an electronic device by incorporating a dustproof and waterproof structure in the electronic device, or a user may purchase and use an aftermarket product (e.g., a protective film or a dustproof and waterproof case). As the use of electronic devices is becoming more common and dustproof and waterproof structures are being incorporated therein, the number of users who enjoy leisure activities while carrying or wearing electronic devices is gradually increasing, and the demand for the performance of dustproof and waterproof structures is also gradually increasing.

SUMMARY

In securing a dustproof and waterproof structure in an electronic device, a waterproof member may be disposed between components to block foreign matter or moisture from entering from the outside. However, a microphone hole or a speaker hole providing a sound input/output path may be exposed or opened to the outside, and the sound input/output path may partially allow the inflow of moisture or the like. When moisture that has flowed into the sound input/output path remains there, it may become an obstacle to sound input/output, and may cause corrosion in the internal space of the electronic device.

Various embodiments of the disclosure are able to provide an electronic device including a speaker structure capable of suppressing inflow of moisture through a sound input/output path or the like.

Various embodiments of the disclosure are able to provide an electronic device including a speaker structure capable of rapidly discharging moisture remaining in a sound input/output path.

According to various embodiments of the disclosure, an electronic device may include: a housing including a first plate including an inner surface defining a portion of a space within the housing and an outer surface forming a portion of an exterior of the housing, and a side member integrally formed with an edge of the inner surface to be substantially perpendicular to the inner surface so as to form a recess with the inner surface, the side member including an opening; a speaker structure disposed in the recess adjacent to the opening, the speaker structure including a first surface including a speaker diaphragm facing the opening and a second surface facing away from the first surface; a fastening member mounted substantially perpendicular to the inner surface so as to fix the speaker structure to the housing; and a fixing member fixed to the housing and disposed to be in contact with at least a portion of the second surface so as to press the second surface.

According to various embodiments, an electronic device may include: a housing including a first plate forming a rear surface of the electronic device, a side member extending from the first plate towards a front surface of the electronic device, and an opening formed to penetrate the side member; a speaker structure mounted, adjacent to the opening, in a recess at least partially defined by the first plate and the side member; and a fixing member configured to support a rear surface of the speaker structure so as to fix the speaker structure to an inner surface of the side member. The fixing member may include a first portion, which comes into contact with a portion of a side surface of the speaker structure, a second portion extending from the first portion and bound to the side member, a third portion extending from the first portion to come into contact with the rear surface of the speaker structure, and a fourth portion extending from the third portion and at least partially supported on an inner surface of the first plate.

In the electronic device according to various embodiments of the disclosure, it is possible to provide a sound output (or input) path by forming an opening penetrating the side member of the housing, but to form a waterproof structure by disposing the speaker structure on the inner surface of the side member adjacent to the opening. In an embodiment, the opening extends along the sound emission direction of the speaker structure. Thus, it is possible to minimize the sound output path arriving at the outside of the housing. For example, by reducing the space in which foreign matter such as moisture may flow or remain and facilitating the discharge of moisture or the like using the sound pressure of the speaker structure, it is possible to suppress or alleviate contamination of the internal space of the electronic device. In another embodiment, the fixing member is able to support the speaker structure so as to keep the same in close contact with the side member, and is able to maintain a stable waterproof structure even at a water pressure of 5 atm or more.

In an embodiment, the first waterproof protrusion 611 may protrude from the edge of the first surface F1, and may form a closed curve along the edge of the first surface F1. For example, when the speaker structure 303 is mounted in the housing 393, the first waterproof protrusion 611 is disposed in the form of protruding from the first surface F1 in the direction in which the opening 415 extends or in the direction in which the speaker structure 303 outputs sound, and may be in close contact with the inner surface I2 of the side member 393b (e.g., the inner wall of the assembly hole 413) around the opening 415. In another embodiment, the second waterproof protrusion 613 may be disposed adjacent to the first waterproof protrusion 611 on the outer surface of the speaker structure 303. For example, the second waterproof protrusion 613 may protrude from the outer surface of the speaker structure 303, and may form a closed curve along the circumference of the speaker structure 303.

According to various embodiments, waterproof members, for example, the first waterproof protrusion 611 and the second waterproof protrusion 613, may be disposed inside the assembly hole 413, and may form a sealing structure between the speaker structure 303 and the side member 393b. For example, a waterproof structure is formed between the speaker structure 303 and the side member 393b, and the opening 415 may be isolated from the recess S by the speaker structure 303 and the waterproof member. The arrangement structure of the waterproof member described above will be described in more detail with reference to FIGS. 11A and 11B.

According to various embodiments, the speaker structure 303 may further include second fastening bosses 615 corresponding to the first fastening bosses 411. In an embodiment, a pair of second fastening bosses 615 may be disposed on opposite sides of the speaker structure 303, respectively. When the speaker structure 303 is mounted in the housing 393, for example, when the first waterproof protrusion 611 or the second waterproof protrusion 613 is accommodated in the assembly hole 413, the second fastening bosses 615 may be seated on the upper end of the first fastening bosses 411.

FIG. 7 is a perspective view illustrating a second fixing member (e.g., the second fixing member 304 in FIG. 3) of an electronic device according to various embodiments of the disclosure.

Referring to FIG. 7, the second fixing member 304 is formed by processing a plate material including a metal, and may be fixed to the housing 393 so as to come into contact with the rear surface of the speaker structure 303, for example, the second surface F2. For example, the second fixing member 304 may have a shape that at least partially surrounds the speaker structure 303 by cutting or bending a plate material into a designed shape. According to an embodiment, the second fixing member 304 may bring the speaker structure 303 into close contact with the inner surface I2 of the side member 393b (e.g., the inner wall of the assembly hole 413) by pressing the second surface F2 of the speaker structure 303.

According to various embodiments, the second fixing member 304 includes a plurality of portions divided according to a bent shape or a region corresponding to another structure (e.g., the housing 393 or the speaker structure 303). For example, the second fixing member 304 may include a first portion 711 that comes into contact with at least a portion of an outer surface of the speaker structure 303, for example, the fourth surface F4, and a second portion 712 extending from a portion of the first portion 711 and coupled to the side member 393b. In an embodiment, the portion of the second fixing member 304 that comes into contact with the second surface F2 may be defined as a third portion 713 extending from the first portion 711. In another embodiment, the second fixing member 304 may include a fourth portion 714, which extends from the third portion 713 and comes into contact with the housing 393. In another embodiment, the second fixing member 304 may include fastening pieces 715 extending away from each other on opposite sides of the first portion 711.

According to various embodiments, the first portion 711 may be disposed to be in contact with the fourth surface F4 so that the speaker structure 303 can be fixed between the inner surface (e.g., the inner surface I1 in FIG. 5A) of the first plate 393a and the first portion 711. Since the speaker structure 303 is in the state of being partially accommodated in the assembly hole 413, and is constrained between the first portion 711 and the inner surface I1, the speaker structure 303 can be stably fixed. In an embodiment, the second portion 712 may be bent or extend in a stepped state with respect to the first portion 711 and may be substantially parallel to the first portion 711. According to an embodiment, the second portion 712 may form a single substantially flat plate shape, rather than forming a step with respect to the first portion 711. For example, the shapes of the first portion 711 and the second portion 712 may vary depending on the shape or assembly structure of the speaker structure 303 or the side member 393b. In another embodiment, the second portion 712 may include a binding protrusion (e.g., a binding hole 712a corresponding to the binding protrusion 419 in FIG. 4) of the side member 393b. For example, the second portion 712 may at least partially come into contact with the top surface U of the side member 393b, and the binding protrusion 419 may be engaged with the binding hole 712a.

According to various embodiments, the third portion 713 may extend from the first portion 711, and may be bent to be inclined or substantially perpendicular to the first portion 711. In an embodiment, when the second fixing member 304 is mounted in the housing 393, the third portion 713 may be disposed to face or to be in contact with the second surface F2. For example, when the second fixing member 304 is mounted in the housing 393, the speaker structure 303 may be disposed between the third portion 713 and the inner surface I2 of the side member 393b (e.g., the inner wall of the assembly hole 413). In an embodiment, the third portion 713 may bring the waterproof member (e.g., the first waterproof protrusion 611 or the second waterproof protrusion 613 in FIG. 6) into close contact with the inner surface I2 of the side member 393b (e.g., the inner wall of the assembly hole 413) by pressing the second surface F2 of the speaker structure 303. In some embodiments, the waterproof member may be made of an elastic body such as silicone or urethane, and may be pressed while being in close contact with the inner surface I2 of the side member 393b. If the waterproof member is made of an elastic body, the waterproof member may be integrally formed with the speaker structure 303 through double injection molding or insert injection molding. In some embodiments, the waterproof member may be bonded to the speaker structure 303 using adhesive tape, an adhesive, or the like.

According to various embodiments, the fourth portion 714 extends from the third portion 713, and may be bent to be inclined or perpendicular to the third portion 713. In an embodiment, the fourth portion 714 may be disposed in the state of facing the inner surface (e.g., the inner surface I1 in FIG. 5A) of the first plate 393a so as to be supported on the inner surface I1. For example, in the inner surface I1, the support groove 421 may be formed to correspond to the fourth portion 714, and the fourth portion 714 may be accommodated in the support groove 421.

According to various embodiments, a pair of fastening pieces 715 may respectively extend from opposite sides of the first portion 711. Each fastening piece 715 may have a shape that is bent so as to come into contact with the fourth surface F4 at one portion thereof and to come into contact with one of the opposite side surfaces of the speaker structure 303 at another portion thereof. For example, the fastening pieces 715 may be bent in a shape that partially surrounds the outer surface of the speaker structure 303 including a portion of the fourth surface F4. The fastening pieces 715 may include fastening holes 715a formed at the ends thereof, respectively, and the fastening holes 715a may be substantially aligned with the first fastening bosses 411 or the second fastening bosses 615.

FIG. 8 is a perspective view illustrating the state in which a speaker structure (e.g., the speaker structure 303 in FIG. 6) is disposed in the housing in an electronic device according to various embodiments of the disclosure.

Referring to FIG. 8, in the state in which the third surface F3 faces the inner surface (e.g., the inner surface I1 in FIG. 5A), the top surface of the speaker structure 303, for example, the fourth surface F4 side, may enter the assembly hole 413 first, and then the third side F3 side may enter the assembly hole 413. When the speaker structure 303 is partially accommodated in the assembly hole 413, the second fastening bosses 615 may be aligned or seated on the upper ends of the first fastening bosses 411. In an embodiment, a flexible printed circuit board 811 extending from the speaker structure 303 may be partially fixed to the inner surface I1.

FIG. 9 is a perspective view illustrating the state in which a second fixing member (e.g., the second fixing member 304 in FIG. 7) is mounted in the housing in an electronic device according to various embodiments of the disclosure.

Referring to FIG. 9, after the speaker structure 303 is first seated on the housing 393, the second fixing member 304 is coupled so as to fix the speaker structure 303 to the housing 393. According to an embodiment, the second fixing member 304 may be seated on the housing 393 in the state in which the first portion 711 is in contact with the fourth surface F4 and the third portion 713 is in contact with the second surface F2. For example, the second portion 712 may be disposed on the top surface U of the side member 393b in the state in which the binding protrusion 419 is engaged with the binding hole 712a, and the fourth portion 714 may be accommodated in the support groove (e.g., the support groove 421 in FIG. 4). According to another embodiment, the end of the fourth portion 714 may be supported on the inner wall of the support groove 421. For example, the second portion 712 and the fourth portion 714 may support the third portion 713 so as to press the rear surface of the speaker structure, for example, the second surface F2.

According to various embodiments, in the state in which the second fixing member 304 is seated on the housing 393, the fastening pieces 715, for example, the fastening holes 715a, may be disposed on the top surfaces 411 of the first fastening bosses 411, with the second fastening bosses 615 interposed therebetween. According to an embodiment, fastening members (e.g., the fastening members 399 in FIG. 3) may sequentially pass through the fastening holes 715a and the second fastening bosses 615 along a direction parallel to the side member 393b (e.g., a direction perpendicular to the sound output direction), and may be fastened to the first fastening bosses 411.

According to various embodiments, the second fixing member 304 or the fastening members 399 may substantially fix the speaker structure 303 to the housing 393. For example, the second portion 712, the third portion 713, or the fourth portion 714 may constrain the speaker structure 303 to the housing 393 in the sound output direction of the speaker structure 303 (e.g., the direction A in FIGS. 11A and 11B). In another embodiment, the first portion 711, the fastening pieces 715, or the fastening members 399 may constrain the speaker structure 303 to the housing 393 in a direction perpendicular to the sound output direction A.

FIG. 10 is a plan view illustrating the state in which a second fixing member (e.g., the second fixing member 304 in FIG. 7) is mounted in the housing in an electronic device according to various embodiments of the disclosure. FIGS. 11A and 11B are cross-sectional views of the housing, which are taken along line A-A′ in FIG. 10. FIG. 12 is a side view illustrating the state in which the second fixing member (e.g., the second fixing member 304 in FIG. 7) is mounted in the housing in the electronic device according to various embodiments of the disclosure. FIG. 13 is a cross-sectional view of the housing, which is taken along line B-B′ in FIG. 12.

Referring to FIGS. 10 to 13, in the state in which the speaker structure 303 and the second fixing member 304 are assembled to the housing 393, the speaker structure 303 may be partially accommodated in the assembly hole 413, and may be supported by the third portion 713. The third portion 713 may substantially press the speaker structure 303, and the waterproofing member 1106, for example, the first waterproof protrusion 611 or the second waterproof protrusion 613, may be in close contact with the inner wall of the assembly hole 413. According to an embodiment, in the state of being assembled to the housing 393, the first waterproof protrusion 611 may protrude from the first surface F1, for example, the sound emission surface of the speaker structure 303, towards the outer surface O2 of the side member 393b along the sound output direction A. In another embodiment, the second waterproof protrusion 613 may protrude from the third surface F3, the fourth surface F4, or the opposite side surfaces of the speaker structure 303 in a direction perpendicular to the sound output direction A. For example, the first waterproof protrusion 611 and the second waterproof protrusion 613 may be in close contact with the inner wall of the assembly hole 413 at different positions, respectively.

According to various embodiments, in the state in which the first waterproof protrusion 611 or the second waterproof protrusion 613 has already been in close contact with the inner wall of the assembly hole 413, when the third portion 713 presses the speaker structure 303 (e.g., the second surface F2), the first waterproof protrusion 611 or the second waterproof protrusion 613 may be compressed. The shaded area indicated by “C” in the first waterproof protrusion 611 or the second waterproof protrusion 613 in FIGS. 11A and 11B exemplifies a pressed portion. In an embodiment, the outer surface of the first waterproof protrusion 611 or the second waterproof protrusion 613 may at least partially include a curved surface or a flat surface. For example, the first waterproof protrusion 611 may include an outer surface, which is at least partially curved, and may be in close contact with the inner surface I2 of the side member 393b (e.g., the inner wall of the assembly hole 413) substantially around the opening 415. When the first waterproof protrusion 611 is pressed while being in close contact with the inner wall of the assembly hole 413, the contact area between the outer surface formed in a curved surface and the inner wall of the assembly hole 413 can be increased. A more stable sealing structure, for example, a waterproof structure, may be formed, for example, between the first waterproof protrusion 611 and the inner wall of the assembly hole 413. In an embodiment, the second waterproof protrusion 613 may include an at least partially planar outer surface. While a portion of the speaker structure 303 is entering the assembly hole 413, the second waterproof protrusion 613 may be gradually pressed while partially rubbing against the inner wall of the assembly hole 413. For example, the second waterproof protrusion 613 may also be in close contact with the inner wall of the assembly hole 413 so as to form a waterproof structure.

According to various embodiments, the diaphragm 1131 of the speaker structure 303 is disposed to face the opening 415, and thus the sound output from the diaphragm 1131 or the speaker structure 303 is emitted substantially through the opening 415 in the sound output direction A. In some embodiments, the diaphragm 1131 may form a portion of the first surface F1, or may be located further inwards than the first surface F1. When the diaphragm 1131 is contaminated by foreign matter such as dust, sound may not be smoothly output. The electronic device (e.g., the electronic device 300 in FIG. 3) may further include a mesh member 1133 mounted in the opening 415 or mounted on the speaker structure 303, thereby blocking the inflow of foreign matter from the outside while outputting or emitting sound through the opening 415.

According to various embodiments, the sound emission surface of the speaker structure 303, for example, the first surface F1, is disposed to substantially face the inner surface I2 of the side member 393b, and the opening 415 may extend through the side member 393b from the inner surface I2 of the side member 393b (e.g., the inner wall of the assembly hole 413 in FIG. 5A) to the outer surface O2 of the side member 393b. For example, the length of the opening 415 may be substantially smaller than the thickness of the side member 393b, and the space for providing a sound emission path inside the side member 393b may be reduced. According to an embodiment, the opening 415 has a cross-sectional area that decreases gradually from the inner surface I2 of the side member 393b or the assembly hole 413 towards the outer surface O2 of the side member 393b. The shape of the opening described above is able to facilitate discharge of foreign matter or moisture while suppressing the inflow of foreign matter or moisture. For example, since the area of the opening 413 is small in the outer surface O2 of the side member 393b, it is possible to suppress the inflow of foreign matter or the like from the outside. Foreign matter that has already flowed into the opening 415 or remains inside the opening 415 can be easily discharged by the sound pressure generated by the operation of the speaker structure 303.

FIGS. 14 and 15 are perspective views illustrating exemplary modified second fixing members 1404 and 1504, respectively, of an electronic device according to various embodiments of the disclosure.

Referring to FIG. 14, the second fixing member 1404 may further include a support, for example, beads 1441 formed on the third portion 713. The beads 1441 may protrude from the third portion 713 to a surface facing the speaker structure (e.g., the speaker structure 303 in FIG. 9). For example, by forming the beads 1441, force for pressing the speaker structure may be increased, and a more stable fixing structure or waterproof structure may be formed. In some embodiments, since the beads 1441 press the speaker structure, various components are able to form a stable waterproof structure even if there are manufacturing errors, which may occur within a design range (e.g., a tolerance), in various components (e.g., the second fixing member 1504 or the speaker structure 303 in FIG. 9).

Referring to FIG. 15, the support formed on the third portion 713 of the second fixing member 1504 may be formed as leaf springs 1541. For example, the leaf springs 1541 may be formed by partially cutting the third portion 713 and bending the cut portions to protrude towards the surface facing the speaker structure. The leaf springs 1541 press the speaker structure so that the speaker structure can be fixed more stably or so that the waterproof performance can be improved.

FIG. 16 is a perspective view illustrating a modification of an electronic device according to various embodiments of the disclosure.

Referring to FIG. 16, the electronic device (e.g., the electronic device 300 in FIG. 3) may include another type of support 1611. For example, the third portion of the second fixing member 304 may have a substantially flat plate shape in a region facing the speaker structure 303, and the support 1611 may be interposed between the third portion of the second fixing member 304 and the speaker structure 303. In an embodiment, the support 1611 may be made of an elastic body such as sponge or urethane, and a stable fixing structure or a waterproof structure can be formed by pressing the speaker structure 303 together with the second fixing member 304.
