Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2018-0051447, filed on May 3, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND

1. Field

The disclosure relates to a conduit connecting the inside and outside of an electronic device.

2. Description of Related Art

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

A speaker arranged inside an electronic device may directly emit its sound to the outside, and may also emit the sound to the outside of the electronic device by using a conduit. When the speaker is arranged to directly emit sound therefrom, a complicated structure such as a conduit may become unnecessary, but there may be a limit on the position in which the speaker can be arranged. When a conduit is used to emit sound to the outside, the speaker can be arranged in various positions, but the conduit may increase the thickness of the electronic device.

SUMMARY

An electronic device may have a hole or a conduit formed therein so as to connect the inside and outside of the electronic device. As the electronic device becomes thinner, the space for forming the hole or conduit may be reduced. Particularly, in the case of a hole connected through a side surface of the electronic device, the problem of insufficient space may be exacerbated as the electronic device becomes thinner.

For example, in order to implement a conduit of a component such as a speaker on a side surface of an electronic device, a duct may be needed to convert the path of sound vertically emitted from the speaker into a horizontal path. In the case of a speaker module having a horizontal duct laminated and integrated in the thickness direction of the speaker, the thickness occupied by the speaker module may increase.

An electronic device according to an embodiment may have a duct implemented inside the electronic device so as to convert a speaker sound path into a horizontal path, thereby preventing an increase of the thickness occupied by the speaker, and implementing a conduit toward a side surface of the electronic device.

An electronic device according to an embodiment may include: a display; an electronic component; an inner structure including a front surface on which the display is seated, a rear surface having a seating portion for the electronic component formed thereon, and a side surface connecting the front surface and the rear surface; and a housing in which the inner structure is seated. The inner structure may include: a first space formed by indentation of a part of the bottom surface of the seating portion toward the front surface of the inner structure; a second space formed to be open toward the front surface of the inner structure such that the second space is connected to and partially overlaps with the first space in a direction defined toward the front surface of the inner structure; and a duct formed to be open toward the side surface of the inner structure such that the duct is connected to and partially overlaps with the second space in a direction defined toward the rear surface of the inner structure.

A conduit structure according to an embodiment may include: an inner structure including a front surface on which a display is seated, a rear surface having a seating portion for an electronic component formed thereon, and a side surface connecting the front surface and the rear surface; and a housing in which the inner structure is seated. The inner structure may include: a first space formed by indentation of a part of the bottom surface of the seating portion toward the front surface of the inner structure; a second space formed to be open toward the front surface of the inner structure such that the second space is connected to and partially overlaps with the first space in a direction defined toward the front surface of the inner structure; and a duct formed to be open toward the side surface of the inner structure such that the duct is connected to and partially overlaps with the second space in a direction defined toward the rear surface of the inner structure.

The speaker sound path may be converted into a horizontal path such that a conduit is implemented toward a side surface of the electronic device. This increases the degree of freedom of component arrangement in connection with designing the electronic device, and makes it possible to design the electronic device thinner.

The display 500 according to an embodiment may be seated on the upper side of the inner structure 410 and may be identical or similar to the display 330 of FIG. 3.

The inner structure 410 may be seated on the housing 420 according to an embodiment. The housing 420 may have an opening 421 formed in a position corresponding to that of the duct 416 of the inner structure 410.

An upward sloping surface 418 may be formed on the side surface 413 (see FIG. 6A) of the inner structure 410 according to an embodiment in a direction defined from the front surface 411 toward the rear surface. Alternatively, a downward sloping surface 418 may be formed on the side surface 413 of the inner structure 410 in a direction defined from the upper side to the lower side. This may minimize friction occurring between the inner structure 410 and the housing 420 in the process of seating the inner structure 410 on the housing 420 such that the same is naturally seated thereon.

The inner structure 410 according to an embodiment may include a seating portion 417, a first space 414, a second space 415, and a duct 416.

The seating portion 417 according to an embodiment may be a space formed by indentation from the rear surface 412 of the inner structure 410 toward the front surface such that a speaker 430 can be seated therein. A first sealing member 440 may be arranged on the seating portion 417 such that, when the speaker 430 is seated therein, the sound does not diffuse to parts other than the first space 414, thereby preventing the sound from diffusing into the electronic device 400.

The second space 415 may be formed toward the upper side of the inner structure 410 so as to partially overlap with the first space 414, and the overlapping parts may be connected to each other. The second space 415 may be formed to be open to the upper side of the inner structure 410. The duct 416 may be formed toward the lower side of the inner structure 410 so as to partially overlap with the second space 415, and the overlapping parts may be connected to each other. The duct 416 may be formed to be open toward the right side of the inner structure 410.

The part of the second space 415 according to an embodiment, which is open to the upper side of the inner space, may be sealed by a sealing plate 450. A second sealing member 460 formed in a shape corresponding to that of the sealing plate 450 may be arranged between the second space 415 and the sealing plate 450. The sealing plate 450 and the second sealing member 460 may play the role of preventing the sound generated by the speaker 430 from diffusing into the electronic device 400 through the space between the display 500 and the inner structure 410, and the role of gathering the sound such that the same is discharged through the duct 416 and the opening 421 of the housing 420.

A third sealing member 470 may be arranged between the part of the duct 416 according to an embodiment, which is open to the right side of the inner structure 410, and the opening 421 of the housing 420. The third sealing member 470 may be configured to prevent moisture from entering the electronic device 400 through the opening 421 of the housing 420, and to guide the sound generated by the speaker 430 such that the same is discharged to the opening 421 without diffusing to the space between the inner structure 410 and the housing 420. The third sealing member 470 may be made of a water-repellent work mesh or a Gore-Tex® material. The peripheral part of the third sealing member 470 may be made of an elastic material and may seal the space between the inner structure 410 and the housing 420 along the part of connection between the duct 416 and the opening 421.

The fourth sealing member 480 according to an embodiment may seal the space between the housing 420 and the seating portion 417 such that, when the inner structure 410 is seated on the housing 420, the sound does not diffuse to parts other than the first space 414.

According to an embodiment, the sound generated by the speaker 430 may be transferred to the outside through the conduit structure formed by the first space 414, the second space 415, the duct 416, and the opening 421 of the housing 420.

FIG. 9A illustrates the open part of the second space 415 according to an embodiment. FIG. 9B illustrates the open part of the duct 416 according to an embodiment.

With reference to the condition illustrated in FIG. 9A, the open area of the left end of the second space 415 may different from the open area of the right end. For example, the open area 415′ of the passage part that connects the second space 415 and the first space 414 may differ from the open area 415″ of the passage part that connects the second space 415 and the duct 416.

Referring to FIG. 9A and FIG. 9B, according to an embodiment, the open area 415′ of the passage part that connects the second space 415 and the first space 414 may be larger than the open area 415″ of the passage part that connects the second space 415 and the duct 416. Sound is generated radially by and around the speaker 430 as a wave, and the energy thereof diffuses and gradually dissipates in proportion to the distance from the speaker 430. This may appear as a sound that gradually decreases and dissipates. The sound generated by the speaker 430 is configured to be discharged through the opening 421 (see FIG. 5) of the housing 420 (see FIG. 5) after moving along the conduit structure according to an embodiment and via the duct 416. A predetermined magnitude of sound can be secured by guiding the sound generated by the speaker 430 (see FIG. 6B) such that the same is gathered to the duct 416 instead of diffusing radially and dissipating. Accordingly, in connection with the first space 414 into which the sound generated by the speaker 430 is initially introduced, the open area 415′ of the passage part that connects the second space 415 and the first space 414 is formed to be large such that a large amount of sound energy can be introduced, and the open area 415″ of the passage part that connects the second space 415 and the duct 416 may be formed to be narrow such that, when the introduced sound energy is discharged, the energy is concentrated and discharged through the opening 421.

The sealing plate 450 (see FIG. 6A) according to an embodiment may be formed in the shape of a trapezoid, the left side of which is relatively wider than the right side thereof, in view of the above-mentioned characteristics of the second space 415. The sealing plate 450 itself, however, may be also formed in various shapes, including a circle and a quadrangle, regardless of the structure of the second space 415.
