In this state, the casing components 1 and 2 are exposed, and the display panel 9 is disposed so as to be held by the casing component 1. The display unit 10 shown in FIG. 1 is realized by the display panel 9 shown in FIG. The display panel 9 may also serve as a touch panel. The housing of the electronic device 101 is configured by combining the upper housing component 1 and the lower housing component 2. The housing component 1 is provided with two first openings 31.

  Actually, the housing component 1 may be provided with another opening in addition to the first opening 31, but the illustration is omitted here. The number of the first openings 31 is 2 here, but may be a number other than 2.

  FIG. 3 shows a cross-sectional view of the state where the lower casing component 2 is removed from the structure shown in FIG.

The first surface 1 a has a protrusion 6 at a position between the board-shaped component 8 and the adhesive member 3 when viewed in plan. The board-like component 8 is arranged so as to avoid the position of the adhesive member 3 when viewed in plan.

  Even if only the configuration described so far is effective, in the electronic device 101 in the present embodiment, it is more preferable that the first component includes the housing component 1 and the housing component 1. Has a second surface 1b facing away from the first surface 1a, and the housing component 1 has a first opening 31 that communicates the first surface 1a and the second surface 1b, and the adhesive member 3 Are arranged so as to surround the first opening 31, and the second component includes a component holder 4 that holds the target component 5. The component holder 4 has a second opening 32 that communicates the first opening 31 and the target component 5.

  In this example, the target component 5 is a speaker. In this example, the component holder 4 is a speaker holder. Here, the first component includes the housing component 1. However, only the housing component 1 may be the first component, and the combination of the housing component 1 and something else is the first component. There may be. Although the second component includes the component holder 4, only the component holder 4 may be the second component, or the combination of the component holder 4 and something else may be the second component.

  The place where the housing component 1 is taken out alone is shown in FIGS. As shown in FIG. 4, irregularities may be provided on the surface of the casing component 1. The entire downward surface visible in FIG. 4 is the first surface 1a, and the entire upward surface is the second surface 1b. A perspective view of the vicinity of the first opening 31 in the housing component 1 is shown in FIG. 5, and a plan view is shown in FIG. In FIG. 6, the longitudinal direction 81 of the housing component 1 is indicated by a double-headed arrow. In FIG. 6, a state in which the board-like component 8 overlaps the first surface 1a is indicated by a two-dot chain line. The board-like component 8 may be a component mounting board, for example. In the example shown in FIGS. 5 and 6, the two first openings 31 are arranged in a symmetrical positional relationship at one end of the housing component 1. An adhesive member disposition region 14 is provided so as to surround each of the first openings 31. The adhesive member arrangement area 14 is an area in which the adhesive member 3 (see FIG. 3) is arranged. It is preferable that the surface of the adhesive member arrangement region 14 is processed so as to be easily adhered. In this example, the protrusion 6 is arranged outside the adhesive member arrangement region 14. As shown in FIG. 6, the end of the board-like component 8 has a notch so as to avoid the first opening 31, the adhesive member arrangement region 14, and the protrusion 6.

  Here, for convenience of explanation, the case component 1 is described as a single component, but actually, the case component 1 may be a combination of a plurality of components. The casing component 1 is not limited to only one type of material, and may be a combination of components made of different materials. The housing component 1 may be, for example, a combination of a metal component and a resin component. Further, the casing component 1 alone may constitute the entire casing of the electronic device, or may constitute only a part of the casing of the electronic device.

  The place which took out the component holder 4 independently is shown in FIGS. FIG. 7 is a perspective view when the component housing portion 17 is arranged so as to face upward. FIG. 8 is a perspective view of the component holder 4 shown in FIG. FIG. 9 is a plan view, and FIG. 10 is a cross-sectional view taken along line XX in FIG. The component holder 4 is roughly symmetrical in shape, but also includes an asymmetrical portion. The component holder 4 includes two component accommodating portions 17. The component accommodating portion 17 is a recess for accommodating the target component 5. The two component housing parts 17 are arranged so as to be substantially symmetrical. An oval adhesive member arrangement region 16 is provided in the vicinity of the outer edge of the bottom surface of the component housing portion 17. A bottom plate 15 and a second opening 32 are provided in an inner region surrounded by the adhesive member arrangement region 16 in the bottom surface of the component housing portion 17. As shown in FIG. 7, the bottom plate 15 is lower than the adhesive member arrangement region 16. The adhesive member placement region 16 is a region where the adhesive member 12 (see FIG. 3) is placed. It is preferable that the surface of the adhesive member arrangement region 16 is processed so as to be easily adhered. As shown in FIG. 10, the second opening 32 may be a through hole whose opening area changes in the middle of the thickness direction.

  The place where the target component 5 is taken out alone is shown in FIG. The shape of the target component 5 shown in FIG. 11 is merely an example, and is not necessarily such a shape. A lead wire may protrude from the target component 5. In the present embodiment, as an example, the target component 5 has been described as a speaker, but the type of the target component 5 is not limited to this. The number of the component accommodating portions 17 provided in one component holder 4 is 2 here, but is not limited to 2, and may be another number.

(Action / Effect)
In the present embodiment, the displacement of the board-like component 8 is limited by the protrusions 6 provided on the first surface 1a of the first component. It is prevented. As a result, durability against impact can be improved.

  Further, preferably in the present embodiment, the first component includes the casing component 1, the second component includes the component holder 4, the casing component 1 has the first opening 31, and the component holder 4 is the first In the case of such a configuration, the first surface 1a of the housing component 1 is located at a position between the board-shaped component 8 and the adhesive member 3. Since the projection 6 is provided, even when the board-like component 8 is displaced due to an impact such as dropping, further displacement is prevented by the end 8 e of the board-like component 8 colliding with the projection 6. Therefore, it is possible to prevent a situation in which the end 8e of the substrate-like component 8 collides with the adhesive member 3 or the component holder 4 and impairs the adhesion between the component holder 4 and the housing component 1. Therefore, according to the present embodiment, in the electronic device, durability against an impact such as dropping can be improved while maintaining the communication state by the first opening and the second opening.

  In addition, it is preferable that the 1st opening part 31 exists in one edge part of the housing component 1, and the processus | protrusion 6 exists in the side near the center of the housing component 1 rather than the adhesive member 3. FIG. That the protrusion 6 is closer to the center of the housing component 1 than the adhesive member 3, that is, the board-shaped component 8 is also closer to the center of the housing component 1 than the adhesive member 3 is. is there. In the case of such a configuration, the board-like part 8 near the center of the housing part 1 is displaced toward the end by an impact, and a large load may be applied from the board-like part 8, Since the displacement of the substrate-like component 8 can be stopped by the protrusions 6, a particularly remarkable effect can be obtained regarding the protection of the adhesive member 3.

  The protrusion 6 is preferably a linear protrusion extending so as to block the board-shaped component 8 and the adhesive member 3. The protrusion 6 illustrated in FIGS. 5 and 6 satisfies this condition. Since the protrusion 6 is such a linear protrusion, the protrusion 6 disperses the load received from the substrate-like member 8 when the protrusion 6 receives the displacement of the substrate-like member 8 caused by the impact of the electronic device. I can take it. Therefore, the displacement of the substrate-like member 8 can be effectively prevented. The protrusion 6 is “a linear protrusion extending so as to block the substrate-like component 8 and the adhesive member 3”, for example, in the case of a positional relationship as shown in FIG. As shown in FIG. 5, the case where the protrusion 6 is shorter than the adhesive member 3 is also applicable.

  The casing component 1 has a shape having a longitudinal direction, and there is a portion where the substrate-like component 8 and the adhesive member 3 are arranged along the longitudinal direction 81. Are preferably provided at positions sandwiched between the board-shaped component 8 and the adhesive member 3. The configuration illustrated in FIG. 6 satisfies this condition. In the case of such a configuration, the protrusion 6 can efficiently prevent displacement of the substrate-like component 8 that occurs along the longitudinal direction 81. The “location where the substrate-like component 8 and the adhesive member 3 are arranged along the longitudinal direction 81” may be a location where such an arrangement order is locally established. Since the projection 6 only needs to be “provided at a position sandwiched between the board-shaped component 8 and the adhesive member 3 along the longitudinal direction 81”, the length and shape of the projection 6 are not limited. For example, as shown in FIGS. 12 and 13, the protrusion 6 may be a linear protrusion, but this is not a limitation. For example, as shown in FIG. 14, the structure provided with the dotted | punctate protrusion 6i may be sufficient. In FIG. 14, only one dot-like protrusion 6i is provided, but a plurality of dot-like protrusions 6i may be provided.

  The casing component 1 has a shape having a longitudinal direction 81, and there is a portion where the substrate-like component 8 and the adhesive member 3 are arranged along the longitudinal direction 81. 6 extends in a direction perpendicular to the longitudinal direction 81 at the location. In the configuration illustrated in FIG. 6, this condition is satisfied. Since the protrusions 6 that are linear protrusions extend in a direction perpendicular to the longitudinal direction 81 in this way, the protrusions 6 can efficiently block the displacement of the board-like component 8. The configuration illustrated in FIGS. 12 and 13 also satisfies this condition.

  The target component 5 is preferably a component that inputs or outputs sound. Examples of components that input or output sound include a speaker and a microphone. As described above, when the target component 5 is a component that inputs or outputs sound, it is required that the sound can be transmitted between the target component 5 and the outside. In the present embodiment, the first opening is used. By connecting the part 31 and the second opening 32, a sound transmission path is secured between the target component 5 and the outside. Since the portion corresponding to the joint of the first opening 31 and the second opening 32 is closed by the adhesive members 3 and 12, sound can be transmitted efficiently.

  The adhesive member 3 is preferably a waterproof double-sided tape. Thus, when it is going to give waterproofness by using a waterproof double-sided tape, when the board-shaped component 8 collides with the adhesive member 3 or the component holder 4, there exists a possibility that the waterproof function of a waterproof double-sided tape may be impaired. However, in the present embodiment, since the projection 6 is provided at a position between the board-like component 8 and the adhesive member 3 on the first surface 1a, the board-like component 8 is attached to the adhesive member 3 or Colliding with the component holder 4 is prevented and contributes to securing waterproofness. In particular, in an electronic device in which waterproofing is a problem by using a waterproof double-sided tape for the adhesive member 3, this effect becomes remarkable. The adhesive member 12 is also preferably a waterproof double-sided tape.

  The adhesive member 3 is not limited to the double-sided tape, and may be another member. Moreover, the adhesive member 3 is not limited to an independent shape such as a tape, for example, and may be one in which an adhesive is applied and sandwiched. In that case, the adhesive layer formed by application corresponds to the adhesive member 3.

  As shown in FIG. 6, when viewed in plan, the substrate-like component 8 has a notch at the end, the adhesive member 3 is disposed inside the notch, and the protrusion 6 is located inside the notch. It is preferable that it is arrange | positioned at least in the innermost part of the said notch. By adopting this configuration, the board-like component 8 can be disposed in the space around the adhesive member 3, and the space can be effectively utilized. Even in such a case, the adhesive member 3 can be disposed by providing a notch at the end of the board-like component 8. In this case, the adhesive member 3 can be efficiently protected by the protrusion 6 arranged at the innermost part of the notch.

  In the present embodiment, the first component includes the casing component 1 and the second component includes the component holder 4. However, the first component is a component other than the casing component. Also good. Similarly, the second component may be a component other than the component holder 4. For example, when the housing of the electronic device includes a front part and a rear part, the first part may be a front part and the second part may be a rear part. The front and rear may be reversed.

  In the present embodiment, as illustrated in FIGS. 1 and 2, the example in which the first opening 31 is provided on the front surface of the electronic device has been described. In the present embodiment, since the target component 5 is a speaker, the fact that the first opening 31 is provided in front of the electronic device means that the sound from the speaker of the electronic device is from the front of the electronic device. It means that it is discharged toward the front. However, the 1st opening part 31 is not necessarily arrange | positioned in the front surface of the electronic device. The 1st opening part 31 may be provided in other than the front of an electronic device, ie, a back surface, a side surface etc. In the present embodiment, as shown in FIG. 3, the first opening 31 and the second opening 32 are in a substantially overlapping positional relationship, and the sound that has passed through the second opening 32 from the target component 5 has passed. The first opening 31 and the second opening 32 are not overlapped with each other, but the first opening 31 and the second opening 32 do not overlap each other. It may be. In that case, the sound that has exited the target component 5 and passed through the second opening 32 passes through an appropriate path inside the casing component 1 and then passes through the first opening 31 of the casing component 1 to form the casing. A structure that goes out of the part 1 can be considered. Here, the case where the sound emitted from the target component 5 goes outside has been described as an example, but the same applies to the case where the sound enters the target component 5 from the outside. The same applies even if the reason why the target component 5 should be communicated with the outside is other than sound input / output.

  In the present embodiment, as shown in FIG. 3, the protrusion 6 is provided inside a region where the target component 5 is projected onto the housing component 1. In other words, the protrusion 6 is in a position overlapping the target component 5. This is merely an example, and the configuration is not limited to this. The protrusion 6 may be provided outside the region where the target component 5 is projected onto the housing component 1. However, as in the example shown in FIG. 3, it is preferable to arrange the protrusion 6 inside the region where the target component 5 is projected onto the housing component 1 because the degree of freedom in design increases. For example, when the size of the target component 5 is larger than the size of the first opening 31 when viewed in plan, it is preferable to arrange the protrusions 6 in the projection area of the target component 5 because space saving is achieved.

(Modification)
Variations in the positional relationship among the adhesive member 3, the board-shaped component 8, and the protrusions will be further described. 12 to 24, the positional relationships among the adhesive member 3, the board-shaped component 8, and the protrusions are respectively shown in plan views. 12 to 14 show an example in which the end of the board-like component 8 is a simple straight line and the adhesive member 3 is disposed in the vicinity thereof. There are various things.

  For example, as shown in FIG. 15, the L-shaped side of the board-like component 8 is arranged so as to be close to two adjacent sides of the adhesive member 3 arranged in a substantially rectangular shape, that is, two sides forming an L-shape. In this case, as shown in FIG. 15, it is preferable to provide an L-shaped protrusion 6 j between the adhesive member 3 and the board-shaped component 8. The protrusion 6j shown in FIG. 15 is a continuous protrusion, but as shown in FIG. 16, the separate linear protrusions 6a and 6b may be arranged so as to be substantially L-shaped.

  As shown in FIG. 17, when the board-like components 8a and 8b are arranged with the adhesive member 3 interposed therebetween, linear protrusions 6a along two sides of the adhesive member 3 facing the board-like components 8a and 8b, respectively. , 6b may be arranged. In FIG. 17, the substrate-like components 8a and 8b are shown as being separate components, but the substrate-like components 8a and 8b may be integrated components connected in other places that do not appear in this figure. .

  As shown in FIG. 18, a configuration in which the opening 18 is provided in the substrate-like component 8 and the adhesive member 3 and the first opening 31 are exposed from the opening 18 is also conceivable. In this case, it is preferable that the protrusions 6 a and 6 b are provided along two sides of the adhesive member 3 so as to sandwich the adhesive member 3 while being aligned in the longitudinal direction 81. Even if only one of the protrusions 6a and 6b is provided, a certain effect can be obtained, but it is preferable that the adhesive member 3 is sandwiched between the two sides facing each other. Furthermore, as shown in FIG. 19, the opening 18 may be provided with protrusions 6 a, 6 b, 6 c, 6 d along all four sides so as to surround the adhesive member 3. In this case, there is a disadvantage that a large installation space for the protrusions is required, but in the sense that the adhesive member 3 is protected from the collision of the board-like component 8, more reliable protection can be expected, which is further preferable. In the example shown in FIG. 19, the protrusions 6a, 6b, 6c, and 6d are shown as four independent linear protrusions, but some or all of them may be connected.

  As shown in FIG. 20, the same can be considered when the adhesive member 3 and the first opening 31 are disposed so as to be surrounded by the plurality of board-like components 8a, 8b, and 8c. That is, a configuration in which the protrusions 6a, 6b, 6c, and 6d are provided along all four sides so as to surround the adhesive member 3 is preferable.

  As shown in FIG. 21, when the board-shaped component 8 has a notch, as shown in FIG. 21, the protrusion 6 may be arranged in the innermost part of the notch. Thus, it is more preferable if the projections 6a, 6b, and 6c are arranged so as to surround the adhesive member 3 from three sides inside the notch, that is, to form a U-shape. In this case, there is a drawback that a large installation space for the protrusions is required, but more reliable protection can be expected in the sense that the adhesive member 3 is protected from the collision of the board-like component 8.

  Up to this point, the first opening 31 has been described as being substantially rectangular. However, the shape of the first opening 31 is not limited to being substantially rectangular, but may be other shapes. For example, as shown in FIG. 23, the first opening 31 may be circular. In that case, the adhesive member 3 surrounding the first opening 31 may also be provided in an annular shape. Even if the outer shape of the adhesive member 3 is circular, the protrusion 6 may be linear as shown in FIG. Alternatively, as shown in FIG. 24, a curved projection 6f may be provided in accordance with the shape of the cutout of the board-like component 8.

  The shape of the first opening 31, the outer shape of the adhesive member 3, the shape of the end of the board-like component, and the like when viewed in plan are not limited to those exemplified so far.
