DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The electronic device according to the present embodiment may be a mobile electronic device such as a mobile phone or a smartphone. The electronic device according to the present embodiment is not limited to a mobile electronic device. The electronic device may be various electronic devices such as a desktop PC (Personal Computer), a notebook PC, a tablet PC, a home appliance, an industrial device or a FA (Factory Automation) device, or a dedicated terminal.

[0010] As shown in Fig. 1, an electronic device 1 according to an embodiment includes a housing 10 and a display 12. The housing 10 holds the display 12. The display 12 may be, for example, a display device such as a liquid crystal display, an organic electroluminescence (EL) display, or an inorganic EL display, but is not limited thereto. The display 12 may be configured as a touch panel including a touch sensor. The electronic device 1 further includes a speaker 14 (see Fig. 4 or Fig. 5).

[0011] In this embodiment, the shape of the housing 10 is an approximately rectangular parallelepiped. The housing 10 has a first surface on which the display 12 is located, and a second surface located on the opposite side of the front surface. The first surface faces in the positive direction of the Z axis. The first surface is also referred to as the front surface. The second surface faces in the negative direction of the Z axis. The second surface is also referred to as the back surface. Each surface of the housing 10 is not limited to a flat surface, but may be a curved surface including a curved shape. Each surface of the housing 10 may be connected to intersect with each other. Each surface of the housing 10 may be smoothly connected to each other. The shape of the housing 10 is not limited to an approximately rectangular parallelepiped, but may be various other shapes.

[0012] The electronic device 1 includes an upper end cover 20 located at the end on the positive side of the Y axis, and a lower end cover 30 located at the end on the negative side of the Y axis. The upper end cover 20 and the lower end cover 30 are also collectively referred to as end covers. The electronic device 1 includes an impact absorbing member 40 located at the end on the positive side of the Y axis, and an impact absorbing member 50 located at the end on the negative side of the Y axis.

[0013] 2, electronic device 1 includes mesh portion 24 at the end on the positive side of the Y axis. When speaker 14 is disposed inside housing 10, mesh portions 24, 35, and 36 communicate the space inside housing 10 in which speaker 14 is disposed with the space outside housing 10 so that sound generated from speaker 14 is transmitted to the outside of housing 10. Mesh portion 24 may be configured in a mesh shape, for example, or may have a plurality of holes.

[0014] A portion of the mesh portion 24 is covered by the upper end cover 20 in a plan view of the first surface of the housing 10. In other words, the upper end cover 20 is positioned so as to overlap a portion of the mesh portion 24 in a plan view of the mesh portion 24.

[0015] 3, the electronic device 1 has mesh portions 35 and 36 at the end on the negative side of the Y axis. A part of the mesh portion 35 and a part of the mesh portion 36 are covered by the bottom end cover 30 in a plan view of the first surface of the housing 10. In other words, the bottom end cover 30 is positioned so as to overlap a part of the mesh portion 35 and a part of the mesh portion 36 in a plan view of the mesh portions 35 and 36.

[0016] The upper end cover 20 has a portion extending along the mesh portion 24 without contacting the mesh portion 24, and a protrusion 23 in contact with the mesh portion 24. The lower end cover 30 has a portion extending along the mesh portions 35 and 36 without contacting the mesh portions 35 and 36, a protrusion 33 in contact with the mesh portion 35, and a protrusion 34 in contact with the mesh portion 36. The portion of the upper end cover 20 extending along the mesh portion 24 without contacting the mesh portion 24, and the portion of the lower end cover 30 extending along the mesh portions 35 and 36 without contacting the mesh portions 35 and 36 are also referred to as the first portion. The portion of the upper end cover 20 in contact with the mesh portion 24, and the portion of the lower end cover 30 in contact with the mesh portions 35 and 36 are also referred to as the second portion.

[0017] The upper end cover 20 and the lower end cover 30 are also referred to as protective parts for the mesh parts 24, 35 and 36. The protective parts have a first part and a second part. The first part extends along the mesh parts without contacting the mesh parts. The second part protrudes from the protective part toward the mesh parts and contacts the mesh parts at its tip.

[0018] 4 and 5, the housing 10 has walls 16A and 16B and a bottom 16C that define a space inside the mesh portion 36. The space defined by the walls 16A and 16B and the bottom 16C is used to collect water that has entered the inside of the housing 10, as described below, and is also referred to as a water reservoir 16. The mesh portion 36 is disposed in a position that covers the water reservoir 16. Moreover, the water reservoir 16 defined by the walls 16A and 16B and the bottom 16C is located on the opposite side of the lower end cover 30 from the mesh portion 36.

[0019] The water reservoir 16 is located between the speaker 14 disposed inside the housing 10 and the space extending outside the mesh portion 36. The bottom end cover 30 is located outside the housing 10 when viewed from the mesh portion 36. The bottom end cover 30 has a protrusion 34 that protrudes toward the mesh portion 36. The protrusion 34 comes into contact with the mesh portion 36 at its tip. The protrusion 34 may be positioned so as to press the mesh portion 36.

[0020] Here, in the electronic device 1, the mesh portion 36 divides a space extending outside the housing 10 from a space extending inside the housing 10, making it difficult for water to enter the inside of the housing 10. However, water may pass through the mesh portion 36 due to high water pressure being applied to the mesh portion 36. The water that passes through the mesh portion 36 enters the inside of the housing 10. The water that enters the inside of the housing 10 is difficult to discharge to the outside by the mesh portion 36.

[0021] Specifically, as illustrated in Fig. 6A, when the invading water 5 comes into contact with the mesh portion 36, a curved meniscus surface 5A is formed in the gaps of the mesh portion 36, and the invading water 5 may not be able to pass through the mesh portion 36. In this case, the mesh spacing of the mesh portion 36 is equal to or smaller than the spacing that generates a meniscus of the invading water 5.

[0022] In the electronic device 1 according to this embodiment, as illustrated in FIG. 6B, the protrusions 34 are in contact with the mesh portion 36. When the protrusions 34 are in contact with the mesh portion 36, a meniscus is generated between the mesh portion 36 and the protrusions 34. When the meniscus is generated between the mesh portion 36 and the protrusions 34, the meniscus curved surface 5A formed in the gap of the mesh portion 36 is destroyed. As a result, the intruding water 5 is easily able to pass through the mesh portion 36. For example, the intruding water 5 is discharged to the outside of the housing 10 by simply shaking the electronic device 1 lightly.

[0023] By contacting the mesh portion 36 from the outside of the housing 10 with the protrusions 34, water outside the housing 10 tends to remain on the side of the protrusions 34. Therefore, in the portion where the protrusions 34 contact the mesh portion 36 from the outside, water tends to pass through the mesh portion 36 from the inside to the outside, but does not easily pass through from the outside to the inside.

[0024] The mesh portion 36 may be subjected to a water-repellent treatment using a waterproof material such as a fluorine-based resin or a silicone-based resin. The mesh portion 36 may be made of a waterproof synthetic fiber such as a fluorine-based resin or a silicone-based resin. By subjecting the mesh portion 36 to a water-repellent treatment or by making the mesh portion 36 of a waterproof synthetic fiber, water on the outside of the housing 10 tends to remain on the side of the protrusions 34. On the other hand, in the portion where the protrusions 34 contact the mesh portion 36 from the outside, water tends to pass through the mesh portion 36 from the inside to the outside.

[0025] When water enters the inside of the housing 10, the water is collected in the water reservoir portion 16 that the mesh portion 36 faces, so that the water can be efficiently discharged from the mesh portion 36. The protrusion portion 34 may be disposed so as to contact the mesh portion 36 at the portion of the mesh portion 36 that faces the water reservoir portion 16, so that the water collected in the water reservoir portion 16 can be efficiently discharged to the outside of the housing 10.

[0026] Water that has collected near the mesh portion 36 is efficiently discharged. For example, water that has collected in the portion partitioned by the bottom portion 16C is closer to the mesh portion 36 than water that has collected in the portion where the bottom portion 16C does not exist and that communicates with the space of the speaker 14. The protrusion portion 34 may be disposed so as to contact the mesh portion 36 at a portion of the mesh portion 36 that faces the bottom portion 16C. In this manner, water is efficiently discharged to the outside of the housing 10.

[0027] The protrusion 34 may be a boss or a rib. The protrusion 34 may be configured as a plurality of bosses. The protrusion 34 may be arranged so that the contour of the surface that contacts the mesh portion 36 is long. At least a portion of the protrusion 34 may contact the mesh portion 36. In other words, at least a portion of the second portion of the protective portion may contact the mesh portion.

[0028] The portion of the lower end cover 30 extending along the mesh portion 36 may be positioned so as to overlap with the mesh portion 36 over an area smaller than half of the portion of the mesh portion 36 that faces the water pool portion 16. In other words, the first portion of the protective portion may be positioned so as to overlap with the mesh portion 36 over an area smaller than half of the portion of the mesh portion 36 that faces the water pool portion 16 in a plan view of the mesh portion 36. Because the area where the first portion of the protective portion overlaps with the mesh portion 36 is small, the sound generated from the speaker 14 is less likely to be blocked by the protective portion.

[0029] (summary) As described above, in the electronic device 1 according to an embodiment of the present disclosure, the protrusions are brought into contact with the portion of the mesh part facing the water pool from the outside of the housing 10. In this way, water that has entered inside the mesh part is easily discharged to the outside of the housing 10.

[0030] In the device according to the comparative example, the mesh portion facing the internal space is not in contact with anything. In the device according to the comparative example, the meniscus occurs in the mesh portion, so water is difficult to remove to the outside by simply shaking the device. Therefore, it becomes necessary to remove the cover so that water that has entered the inside can be wiped off.

[0031] On the other hand, according to the present disclosure, water is discharged from the mesh portion by merely lightly shaking the electronic device 1. In other words, the electronic device 1 is provided from which water can be easily drained without removing the cover.

[0032] In addition, in the electronic device 1 according to the embodiment of the present disclosure, the second portion of the protective part does not contact the mesh part over a wide area, but only partially contacts the mesh part. In this way, the protective part is less likely to hinder the drainage of water. As a result, water is efficiently drained.

[0033] Although the embodiments of the present disclosure have been described based on the drawings and examples, it should be noted that those skilled in the art can make various modifications or alterations based on the present disclosure. Therefore, it should be noted that these modifications or alterations are included in the scope of the present disclosure. For example, the functions included in each component can be rearranged so as not to be logically inconsistent, and multiple components can be combined into one or divided.
