DETAILED DESCRIPTION OF THE INVENTION

[0008] (Background to this disclosure) An example of an electronic device is a notebook computer (laptop PC). The notebook computer includes a first housing that houses a keyboard and a second housing that houses a display unit. The first and second housings are rotatably connected via a hinge. In such a computer, a speaker unit is built into the first housing, and a through-hole is formed in the first housing to transmit sound emitted by the speaker unit to the outside of the computer.

[0009] Remote work has become increasingly common in recent years. Remote work means that employees work from a location other than the office. The spread of remote work has led to an increase in the number of meetings involving multiple people in different locations. In these cases, there is a need to improve the sound pressure emitted from each person's computer.

[0010] However, there are limitations on the placement position of the speaker unit and the formation position of the through hole, as described below.

[0011] For example, when a through-hole is formed in the surface of the first housing on which the keyboard is disposed, the through-hole is formed on the hinge side of the surface of the first housing because if the through-hole is formed on the opposite side of the surface of the first housing from the hinge, the hand or arm of the user operating the keyboard may block the through-hole.

[0012] Furthermore, with the recent spread of fifth-generation mobile communication systems, for example, there is a demand for computers to be equipped with antennas that support high-speed communications. If this antenna is mounted on the hinge side of the surface of the first housing, the placement position of the speaker unit and the formation position of the through-hole are restricted.

[0013] One solution would be to form a through hole in the rear surface of the first housing. However, when the computer is placed on the user's lap, the through hole is blocked, reducing the sound pressure of the sound emitted from the speaker unit.

[0014] Therefore, the inventors discovered that a recess could be formed on the back surface of the first housing, and a through hole formed in the recess for transmitting sound emitted by the speaker unit to the outside, leading to the following invention.

[0015] The electronic device according to the first aspect of the present disclosure includes: a first housing having a first outer surface on which a keyboard is arranged and a second outer surface facing away from the first outer surface; a second housing that houses a display unit and is connected to the first housing; a speaker unit disposed inside the first housing, a recess formed on the second outer surface; a through hole is formed in at least a part of the surface of the recess; At least a portion of the speaker unit faces at least a portion of the back surface of the recess in which the through hole is formed.

[0016] This configuration reduces the possibility that the through-hole will be blocked by the user's knees, etc. This makes it possible to suppress a decrease in the sound pressure of the sound emitted by the speaker unit.

[0017] In the electronic device according to the second aspect of the present disclosure, The first housing may have a third outer surface located between a peripheral edge of the first outer surface and a peripheral edge of the second outer surface, The recess may be open to the third outer surface.

[0018] With this configuration, the recess is open on the third outer surface in addition to the second outer surface, which allows the sound emitted by the speaker unit to be transmitted to the outside of the electronic device via the opening on the third outer surface.

[0019] In the electronic device according to the third aspect of the present disclosure, The recess may have a bottom surface that is continuous with the third outer surface, The bottom surface may be inclined in a direction approaching the first outer surface toward the third outer surface.

[0020] With this configuration, the distance between the bottom surface of the recess and the second outer surface becomes wider as it approaches the third outer surface. This allows the sound from the speaker unit, which is transmitted to the outside of the electronic device through the opening in the third outer surface, to be spread in the recess. This improves the sound pressure and quality of the sound emitted by the speaker unit.

[0021] In the electronic device according to the fourth aspect of the present disclosure, The bottom surface may be inclined at an angle of 1° to 45° with respect to the second outer surface.

[0022] When an electronic device is used on a desk or lap, sound emitted from the speaker unit toward the desk or lap is reflected by the desk or lap. If the tilt angle is 0°, much of the sound reflected by the desk or lap strikes the bottom surface. This muffles the sound between the desk or lap and the bottom surface, potentially making it difficult for the sound to reach the user's ears. On the other hand, if the tilt angle is greater than 45°, the sound tends to escape horizontally, potentially reducing sound pressure. In contrast, with this configuration, by setting the tilt angle to 1° or more, the sound striking the bottom surface can be reduced. Furthermore, with this configuration, by setting the tilt angle to 45° or less, the sound reverberating between the desk or lap and the bottom surface can be utilized to suppress a reduction in sound pressure.

[0023] In the electronic device according to the fifth aspect of the present disclosure, The recess may have a pair of side surfaces facing each other and each of which is continuous with the third outer surface, At least one of the pair of side surfaces may be inclined toward the third outer surface in a direction that increases the distance between the pair of side surfaces.

[0024] With this configuration, the distance between the pair of side surfaces increases toward the third outer surface, which allows the sound from the speaker unit transmitted to the outside of the electronic device through the opening in the third outer surface to be spread in the recess, thereby improving the sound pressure and quality of the sound emitted by the speaker unit.

[0025] In an electronic device according to a sixth aspect of the present disclosure, The recess may have a pair of side surfaces facing each other and each of which is continuous with the second outer surface, At least one of the pair of side surfaces may be inclined toward the second outer surface in a direction that increases the distance between the pair of side surfaces.

[0026] With this configuration, the distance between the pair of side surfaces becomes wider toward the second outer surface, which allows the sound from the speaker unit transmitted to the outside of the electronic device through the opening in the second outer surface to be spread in the recess, thereby improving the sound pressure and quality of the sound emitted by the speaker unit.

[0027] In the electronic device according to the seventh aspect of the present disclosure, The recess may have a pair of side surfaces facing each other and each of which is continuous with the second outer surface and the third outer surface, The pair of side surfaces may be inclined in a direction increasing the distance between the pair of side surfaces toward the second outer surface, and may be inclined in a direction increasing the distance between the pair of side surfaces toward the third outer surface.

[0028] With this configuration, the distance between the pair of side surfaces becomes wider toward the second outer surface and also wider toward the third outer surface. This allows the sound from the speaker unit, which is transmitted to the outside of the electronic device through the openings in the second and third outer surfaces, to be spread in the recess. This improves the sound pressure and quality of the sound emitted by the speaker unit.

[0029] In an electronic device according to an eighth aspect of the present disclosure, The inclination angle of each of the pair of side surfaces, which inclines in a direction increasing the spacing between the pair of side surfaces toward the third outer surface, with respect to a virtual plane perpendicular to the second outer surface and the third outer surface may be greater than or equal to 5° and less than or equal to 45°.

[0030] In this configuration, the inclination angle is set to 5° or more, which increases the sound spread. Also, in this configuration, the inclination angle is set to 45° or less, which makes it possible to utilize the sound reverberation between the pair of side surfaces and suppress a drop in sound pressure.

[0031] In an electronic device according to a ninth aspect of the present disclosure, The inclination angle of each of the pair of side surfaces, which inclines in a direction increasing the spacing between the pair of side surfaces toward the second outer surface, with respect to a virtual plane perpendicular to the second outer surface and the third outer surface may be greater than or equal to 5° and less than or equal to 45°.

[0032] In this configuration, the inclination angle is set to 5° or more, which increases the sound spread. Also, in this configuration, the inclination angle is set to 45° or less, which makes it possible to utilize the sound reverberation between the pair of side surfaces and suppress a drop in sound pressure.

[0033] In an electronic device according to a tenth aspect of the present disclosure, The third outer surface is a right outer surface located outside one end of the keyboard in the longitudinal direction; a left outer surface located outside the other end of the keyboard in the longitudinal direction and facing opposite to the right outer surface, The recessed portion is a first recess that opens to the right outer surface; a second recess that opens to the left outer surface, The speaker unit includes: a first speaker unit facing at least a part of a back surface of the first recessed portion where the through hole is formed; The speaker may further include a second speaker unit facing at least a part of the surface behind the second recess where the through hole is formed.

[0034] With this configuration, the sound pressure and quality of the sound emitted by the speaker unit can be maintained at a good level in 360 degrees around the electronic device when viewing the first housing from a direction perpendicular to the second outer surface.

[0035] An electronic device according to an eleventh aspect of the present disclosure includes: The device may further include a speaker box that is disposed inside the first housing and in which the speaker unit is mounted.

[0036] This configuration can prevent the sounds emitted from the front and rear of the speaker unit from canceling each other out, thereby improving the sound pressure and quality of the sound emitted by the speaker unit.

[0037] (Embodiment 1) [Electronic equipment] Fig. 1 is a perspective view of an example of an electronic device 1 according to a first embodiment of the present disclosure. Fig. 2 is a bottom view of a housing 2 of the electronic device of Fig. 1. The X, Y, and Z directions in the figure indicate the width, depth, and height directions of the housing 2, respectively.

[0038] As shown in Fig. 1, electronic device 1 is a notebook-type personal computer (laptop PC). Electronic device 1 includes housing 2 and housing 3. Housing 2 is an example of a first housing. Housing 3 is an example of a second housing. Housings 2 and 3 each have a thin, box-shaped outer shell and are rectangular when viewed from above.

[0039] The housing 2 houses a keyboard 4 and a touchpad 5. The housing 3 houses a liquid crystal panel 6. The liquid crystal panel 6 is an example of a display unit. In this specification, the keyboard 4 and the touchpad 5 may be referred to as input units 4, 5, and the liquid crystal panel 6 may be referred to as display unit 6.

[0040] The housings 2 and 3 are connected via a hinge unit 7. The hinge unit 7 is provided at an end of the housing 2 in the depth direction (Y direction). The hinge unit 7 rotatably connects the housings 2 and 3. The hinge unit 7 allows at least one of the housings 2 and 3 to rotate, allowing the electronic device 1 to be opened and closed. Specifically, the hinge unit 7 allows the electronic device 1 to be placed in an open state and a closed state. The "open state" refers to a state in which the housings 2 and 3 are separated from each other, exposing the input units 4 and 5 and the display unit 6. The "closed state" refers to a state in which the housings 2 and 3 are arranged opposite each other, the input units 4 and 5 and the display unit 6 face each other, and the input units 4 and 5 and the display unit 6 are not exposed.

[0041] The housing 2 includes cases 10 and 20. The cases 10 and 20 fit together. The cases 10 and 20 are made of a metal material. Examples of metal materials include magnesium alloys.

[0042] When the electronic device 1 is in the closed state, the case 10 faces the housing 3. When the electronic device 1 is in the closed state, the case 20 is located on the opposite side of the housing 3 from the case 10. The cases 10 and 20 are fixed to each other at the outer periphery of the housing 2 with a plurality of screws.

[0043] The space between the cases 10 and 20 is the internal space of the housing 2. A keyboard 4 and a touchpad 5 are housed in this internal space.

[0044] The case 10 has an outer surface 11. The outer surface 11 is an example of a first outer surface. The outer surface 11 faces the liquid crystal panel 6 of the housing 3 when the electronic device 1 is in the closed state.

[0045] Two openings are formed on the outer surface 11. The keyboard 4 is exposed to the outside of the housing 2 through the larger of the two openings. The touchpad 5 is exposed to the outside of the housing 2 through the smaller of the two openings. In other words, the keyboard 4 and the touchpad 5 are disposed on the outer surface 11.

[0046] 1 and 2, the case 20 has outer surfaces 21 and 22. The outer surface 21 is an example of a second outer surface, and the outer surface 22 is an example of a third outer surface.

[0047] The outer surface 21 faces away from the outer surface 11 of the case 10. The outer surface 21 is located on the opposite side of the housing 3 from the outer surface 11 of the case 10 when the electronic device 1 is in the closed state.

[0048] The outer surface 22 protrudes from the peripheral edge 21A of the outer surface 21 in a direction (Z direction) toward the peripheral edge 11A of the outer surface 11 of the case 10. As shown in FIG. 2, the peripheral edge 21A of the outer surface 21 refers to the edges of the outer surface 21 and the vicinity of those edges. As shown in FIG. 1, the peripheral edge 11A of the outer surface 11 refers to the edges of the outer surface 11 and the vicinity of those edges. The outer surface 22 protrudes to a position where it contacts the peripheral edge 11A of the outer surface 11 of the case 10 or to the vicinity of that position. In other words, the outer surface 22 is located between the peripheral edge 11A of the outer surface 11 and the peripheral edge 21A of the outer surface 21.

[0049] 1 and 2, the outer surface 22 includes a right outer side surface 22A, a left outer side surface 22B, a front outer side surface 22C, and a rear outer side surface 22D. In this specification, when the housing 2 is viewed in the depth direction (Y direction), the outer surface 22 on the right side is defined as the right outer side surface 22A, and the outer surface 22 on the left side is defined as the left outer side surface 22B.

[0050] The right outer surface 22A protrudes in the height direction (Z direction) from one end of the width direction (X direction) of the outer surface 21 and extends along the depth direction (Y direction) of the outer surface 21. The left outer surface 22B faces away from the right outer surface 22A. The left outer surface 22B protrudes in the height direction (Z direction) from the other end of the width direction (X direction) of the outer surface 21 and extends along the depth direction (Y direction) of the outer surface 21.

[0051] The front outer surface 22C protrudes in the height direction (Z direction) from an end of the outer surface 21 on the opposite side from the hinge portion 7 in the depth direction (Y direction), and extends along the width direction (X direction) of the outer surface 21. The front outer surface 22C connects the right outer surface 22A and the left outer surface 22B.

[0052] The rear outer surface 22D protrudes in the height direction (Z direction) from the end of the outer surface 21 on the hinge portion 7 side in the depth direction (Y direction), and extends along the width direction (X direction) of the outer surface 21. The rear outer surface 22D connects the right outer surface 22A and the left outer surface 22B.

[0053] When the housing 2 is viewed from the height direction (Z direction), the outer surface 22 is located outside the keyboard 4. In other words, the right outer surface 22A is located outside one end of the keyboard 4 in the longitudinal direction (X direction). The longitudinal direction of the keyboard 4 corresponds to the width direction (X direction) of the housing 2. The left outer surface 22B is located outside the other end of the keyboard 4 in the longitudinal direction. The front outer surface 22C is located outside the end of the keyboard 4 opposite the hinge unit 7 in the lateral direction. The lateral direction of the keyboard 4 corresponds to the depth direction (Y direction) of the housing 2. The rear outer surface 22D is located outside the end of the keyboard 4 on the hinge unit 7 side in the lateral direction.

[0054] A recess 23 is formed on the outer surface 21 of the housing 2. In the first embodiment, the recess 23 includes two recesses 23A and 23B. The recess 23A is an example of a first recess. The recess 23B is an example of a second recess. In the first embodiment, the depth of the recesses 23A and 23B is set to 1 mm or more. This prevents the recesses 23A and 23B from being blocked from below by the knee or the like when the electronic device 1 is used on the lap or the like. The depth of the recesses 23A and 23B may be less than 1 mm.

[0055] As shown in FIG. 2, the recess 23 is formed in the peripheral edge portion 21A of the outer surface 21. As shown in FIG. 1, the recess 23 is formed at the end portion opposite the hinge portion 7 in the depth direction (Y direction) of the housing 2. As shown in FIG. 2, the recess 23A is formed at one end portion in the width direction (X direction) of the housing 2. The recess 23B is formed at the other end portion in the width direction (X direction) of the housing 2. The position of the recess 23A in the width direction (X direction) is the same as the position of the recess 23B in the width direction (X direction).

[0056] Fig. 3 is a right side view of the first housing of the electronic device of Fig. 1. Fig. 4 is a cross-sectional view of the first housing of the electronic device of Fig. 3 taken along line IV-IV.

[0057] 3 and 4, the recesses 23A and 23B open downward (in the direction opposite to the Z direction) of the housing 2. In other words, the recesses 23A and 23B open to the outer surface 21. That is, the recesses 23A and 23B each have an opening 23a.

[0058] 2 and 4, the recesses 23A and 23B open in the width direction (X direction) of the housing 2. In other words, the recesses 23A and 23B open to the outer surface 22. The recess 23A opens to the right outer surface 22A, and the recess 23B opens to the left outer surface 22B. The recesses 23A and 23B each have an opening 23b. The openings 23a and 23b are continuous.

[0059] The configuration of recess 23A will be described in further detail below. Note that recess 23B has the same configuration as recess 23A, except that recess 23B faces the opposite side to recess 23A in the width direction (X direction) of housing 2. Therefore, a detailed description of the configuration of recess 23B will be omitted.

[0060] Fig. 5 is an enlarged view of a portion V in Fig. 2. Fig. 6 is an enlarged view of a portion VI in Fig. 3. Fig. 7 is an enlarged view of a portion VII in Fig. 4.

[0061] 5 and 6, recess 23A has, as surfaces that constitute recess 23A, a bottom surface 231 and a pair of side surfaces 232, 233. Bottom surface 231 and the pair of side surfaces 232, 233 are examples of surfaces of a recess.

[0062] The bottom surface 231 is continuous with the outer surface 21, the right outer surface 22A, and the pair of side surfaces 232, 233.

[0063] 5, one end of the bottom surface 231 in the width direction (X direction) is continuous with the outer surface 21. As shown in Fig. 6, the other end of the bottom surface 231 of the recess 23A in the width direction (X direction) is continuous with the right outer surface 22A.

[0064] 5 and 6, the bottom surface 231 is sandwiched between a pair of side surfaces 232, 233 on both sides in the depth direction (Y direction) of the housing 2. An end portion of the bottom surface 231 on the front outer side surface 22C side in the depth direction (Y direction) is continuous with the side surface 232. An end portion of the bottom surface 231 on the opposite side to the front outer side surface 22C in the depth direction (Y direction) is continuous with the side surface 233.

[0065] As shown in FIG. 7, bottom surface 231 is inclined from one end of bottom surface 231 in the width direction (X direction) to the other end so as to move away from outer surface 21 in the height direction (Z direction) of housing 2. In other words, bottom surface 231 is inclined in a direction (Z direction) approaching outer surface 11 of housing 3 toward right outer side surface 22A. An inclination angle θ1 of bottom surface 231 with respect to outer surface 21 is, for example, 10°. In the first embodiment, inclination angle θ1 is 10°, but it does not have to be 10°. For example, inclination angle θ1 may be any angle between 1° and 45°.

[0066] 5, 28 through holes 23c are formed in the bottom surface 231. The 28 through holes 23c are arranged in a lattice pattern. The 28 through holes 23c are formed in an area excluding the other end of the bottom surface 231 in the width direction (X direction). In other words, the 28 through holes 23c are formed in a partial area of ​​the bottom surface 231.

[0067] The number of through holes 23c is not limited to 28, and may be, for example, 1 or 40. The arrangement of through holes 23c is not limited to a lattice pattern. For example, through holes 23c may be arranged in a line or in a circle.

[0068] The through-holes 23c may be formed in at least a part of the surface of the recess 23. For example, the through-holes 23c may be formed in the entire area of ​​the bottom surface 231.

[0069] As shown in FIGS. 5 and 6, a pair of side surfaces 232, 233 of the recess 23A are continuous with the bottom surface 231, the outer surface 21, and the right outer surface 22A, respectively.

[0070] 5, the pair of side surfaces 232, 233 are sandwiched from both sides in the depth direction (Y direction) of the housing 2 by the bottom surface 231 and the outer surface 21. Ends of the pair of side surfaces 232, 233 of the recess 23A in the width direction (X direction) are each continuous with the right outer surface 22A.

[0071] 5, the side surface 232 is inclined toward the right outer side surface 22A along the width direction (X direction) of the side surface 232, so as to move away from the side surface 233 in the depth direction (Y direction) of the housing 2. Furthermore, the side surface 233 is inclined toward the right outer side surface 22A along the width direction (X direction) of the side surface 233, so as to move away from the side surface 232 in the depth direction (Y direction) of the housing 2. In other words, the pair of side surfaces 232, 233 are inclined toward the right outer side surface 22A in a direction that increases the distance between the pair of side surfaces 232, 233.

[0072] 6, side surface 232 inclines so as to move away from side surface 233 in the depth direction (Y direction) of housing 2 as it moves away from bottom surface 231 in the height direction (Z direction) of housing 2. Side surface 233 inclines so as to move away from side surface 232 in the depth direction (Y direction) of housing 2 as it moves away from bottom surface 231 in the height direction (Z direction) of housing 2. In other words, the pair of side surfaces 232, 233 incline in a direction that increases the distance between the pair of side surfaces 232, 233 toward outer surface 21.

[0073] As a result of the above, the pair of side surfaces 232, 233 of the recess 23A and the recess 23B are inclined in a direction increasing the distance between the pair of side surfaces 232, 233 toward the right outer surface 22A and the left outer surface 22B, respectively, as shown in Figures 5 and 6, and are also inclined in a direction increasing the distance between the pair of side surfaces 232, 233 toward the outer surface 21.

[0074] As shown in Fig. 5, the inclination angle θ2 of each of the pair of side surfaces 232, 233, which incline in a direction increasing the distance between the pair of side surfaces 232, 233 toward the right outer surface 22A, with respect to the imaginary plane 25 is, for example, 10°. The imaginary plane 25 is a plane perpendicular to the outer surface 21 and the right outer surface 22A. In the first embodiment, the inclination angle θ2 is 10°, but it does not have to be 10°. For example, the inclination angle θ2 may be any angle between 5° and 45°.

[0075] As shown in FIG. 6, the angle of inclination θ3 of each of the pair of side surfaces 232, 233, which inclines in a direction increasing the distance between the pair of side surfaces 232, 233 toward the outer surface 21, with respect to the imaginary plane 25 is, for example, 30°. tilt The inclination angle θ3 is 30°, but it does not have to be 30°. For example, the inclination angle θ3 may be any angle between 5° and 45°.

[0076] FIG. 8 is a diagram showing the internal space of the first housing of the electronic device of FIG. 2, with a portion of the first housing removed.

[0077] 4 and 8, a speaker unit 30 and a speaker box 40 are housed in the internal space of the housing 2. In the first embodiment, the speaker unit 30 includes two speaker units 31 and 32, and the speaker box 40 includes two speaker boxes 41 and 42. The speaker unit 31 is an example of a first speaker unit. The speaker unit 32 is an example of a second speaker unit.

[0078] Each of the speaker units 31 and 32 includes a diaphragm and a magnetic circuit. 31 , 32 are well known, so a detailed description of the configuration of the speaker units 31, 32 will be omitted in this specification.

[0079] The speaker boxes 41 and 42 are hollow and have a roughly rectangular parallelepiped shape. The speaker boxes 41 and 42 have openings. The speaker unit 31 is fitted into the opening of the speaker box 41. In this way, the speaker unit 31 is attached to the speaker box 41. The speaker unit 32 is fitted into the opening of the speaker box 42. In this way, the speaker unit 32 is attached to the speaker box 42.

[0080] In the first embodiment, one speaker unit is attached to one speaker box. That is, in the first embodiment, a full-range speaker is housed in the housing 2. However, multiple speaker units may be attached to one speaker box. That is, a two-way speaker, a three-way speaker, or the like may be housed in the housing 2. Furthermore, the speaker box may have through holes for communicating the inside and outside of the speaker box in addition to the locations where the speaker units are attached. In this way, the speaker unit 30 and the speaker box 40 form a bass reflex speaker.

[0081] 8, the speaker unit 31 and the speaker box 41 are disposed at an end of the housing 2 opposite the hinge portion 7 in the depth direction (Y direction), and at one end of the housing 2 in the width direction (X direction). As shown in FIG. 7, the speaker unit 31 is disposed at a position facing the back surface 231A of the bottom surface 231, which is the surface of the recess 23A on which the through-hole 23c is formed. In the first embodiment, the speaker unit 31 faces the area of ​​the back surface 231A on which the through-hole 23c is formed.

[0082] It is not necessarily required that the entire speaker unit 31 be disposed in a position facing the entire rear surface 231A. In other words, it is sufficient that at least a part of the speaker unit 31 be disposed in a position facing at least a part of the rear surface 231A. It is also not necessarily required that the entire speaker unit 31 be disposed in a position facing the area of ​​the rear surface 231A where the through-hole 23c is formed, and a part of the speaker unit 31 may be disposed in a position facing a part of that area.

[0083] 8, the speaker unit 32 and the speaker box 42 are disposed at the end of the housing 2 opposite the hinge portion 7 in the depth direction (Y direction), and at the other end of the housing 2 in the width direction (X direction). The speaker unit 32 is disposed in the same manner as the speaker unit 31. That is, the speaker unit 32 is disposed at a position facing the back surface of the bottom surface 231, which is the surface of the recess 23B on which the through-hole 23c is formed.

[0084] It is not necessarily required that the entire speaker unit 32 be disposed in a position facing the entire back surface of the bottom surface 231. In other words, it is sufficient that at least a part of the speaker unit 32 be disposed in a position facing at least a part of the back surface of the bottom surface 231. It is also not necessarily required that the entire speaker unit 32 be disposed in a position facing the area of ​​the back surface of the bottom surface 231 where the through-hole 23c is formed, and a part of the speaker unit 32 may be disposed in a position facing a part of that area.

[0085] [effect] According to the electronic device 1 of the first embodiment, the following effects can be achieved.

[0086] The electronic device 1 includes housings 2 and 3, and a speaker unit 30. The housing 2 has an outer surface 11 on which a keyboard 4 is arranged, and an outer surface 21 facing away from the outer surface 11. The housing 3 houses a liquid crystal panel 6 and is connected to the housing 2. The speaker unit 30 is arranged inside the housing 2. A recess 23 is formed in the outer surface 21. A through-hole 23c is formed in a bottom surface 231 of the recess 23. At least a portion of the speaker unit 30 faces at least a portion of a back surface 231A of the bottom surface 231 of the recess 23 in which the through-hole 23c is formed.

[0087] This configuration reduces the possibility that through-hole 23c will be blocked by the user's knees, etc. Therefore, a decrease in the sound pressure of the sound emitted by speaker unit 30 can be suppressed.

[0088] The housing 2 has an outer surface 22 located between the peripheral edge portion 11A of the outer surface 11 and the peripheral edge portion 21A of the outer surface 21. The recess 23 opens to the outer surface 22.

[0089] With this configuration, recess 23 is open not only on outer surface 21 but also on outer surface 22. This allows sound emitted by speaker unit 30 to be transmitted to the outside of electronic device 1 via opening 23b in outer surface 22.

[0090] The recess 23 has a bottom surface 231 that is continuous with the outer surface 22. The bottom surface 231 is inclined toward the outer surface 22 in a direction approaching the outer surface 11.

[0091] With this configuration, the distance between the bottom surface 231 of the recess 23 and the outer surface 21 becomes wider toward the outer surface 22. This allows the sound of the speaker unit 30, which is transmitted to the outside of the electronic device via the opening 23b of the outer surface 22, to be spread in the recess 23. This allows the sound pressure and sound quality of the sound emitted by the speaker unit 30 to be improved.

[0092] The inclination angle θ1 of the bottom surface 231 with respect to the outer surface 21 is equal to or greater than 1° and equal to or less than 45°.

[0093] When the electronic device 1 is used on a desk, on a person's lap, or the like, sound emitted from the speaker unit 30 toward the desk, on a person's lap, or the like is reflected by the desk, on a person's lap, or the like. If the tilt angle θ1 is 0°, much of the sound reflected by the desk, on a person's lap, or the like strikes the bottom surface 231. As a result, the sound may be muffled between the desk, on a person's lap, or the like and the bottom surface 231, making it difficult for the sound to reach the user's ears. On the other hand, if the tilt angle θ1 is greater than 45°, the sound may be more likely to escape horizontally, resulting in a decrease in sound pressure. In contrast, in this configuration, by setting the tilt angle θ1 to 1° or more, the sound striking the bottom surface 231 can be reduced. Furthermore, in this configuration, by setting the tilt angle θ1 to 45° or less, the sound reverberation between the desk, on a person's lap, or the like and the bottom surface 231 can be utilized to suppress a decrease in sound pressure.

[0094] Furthermore, in this configuration, the inclination angle θ1 is set to 45° or less. Therefore, the effect of sound reverberation between the pair of side surfaces 232, 233 based on the inclination angle θ2 and the effect of sound reverberation between the pair of side surfaces 232, 233 based on the inclination angle θ3 can be greatly enhanced by the synergistic effect of sound reverberation based on the inclination angle θ1.

[0095] The recess 23 has a pair of side surfaces 232, 233 that face each other and are continuous with the outer surfaces 21, 22. The pair of side surfaces 232, 233 are inclined toward the outer surface 21 in a direction that increases the distance between the pair of side surfaces 232, 233, and are also inclined toward the outer surface 22 in a direction that increases the distance between the pair of side surfaces 232, 233.

[0096] With this configuration, the distance between the pair of side surfaces 232, 233 becomes wider toward the outer surface 21 and also toward the outer surface 22. This allows the sound of the speaker unit 31, which is transmitted to the outside of the electronic device 1 through the opening 23a of the outer surface 21 and the opening 23b of the outer surface 22, to be spread in the recess 23. This allows the sound pressure and sound quality of the sound emitted by the speaker unit 31 to be improved.

[0097] The inclination angle θ2 of each of the pair of side surfaces 232, 233 that inclines in a direction increasing the distance between the pair of side surfaces 232, 233 toward the outer surface 22 with respect to the imaginary plane 25 perpendicular to the outer surfaces 21, 22 is 5° or more and 45° or less.

[0098] In this configuration, the inclination angle θ2 is set to 5° or more, thereby increasing the sound spread in the Y direction. Furthermore, in this configuration, the inclination angle θ2 is set to 45° or less. This makes it possible to utilize sound reverberation between the pair of side surfaces 232, 233 to suppress a drop in sound pressure. Furthermore, in this configuration, the inclination angle θ2 is set to 45° or less. Therefore, the effect of sound reverberation between the desk on which electronic device 1 is placed, laps, etc., and bottom surface 231, and the effect of sound reverberation between the pair of side surfaces 232, 233 based on the inclination angle θ3, can be greatly enhanced by the effect of sound reverberation based on the inclination angle θ2.

[0099] The inclination angle θ3 of each of the pair of side surfaces 232, 233 inclined in a direction increasing the distance between the pair of side surfaces 232, 233 toward the outer surface 21 with respect to an imaginary plane 25 perpendicular to the outer surfaces 21, 22 is 5° or more and 45° or less.

[0100] In this configuration, the inclination angle θ3 is set to 5° or more, thereby increasing the sound spread in the Z direction. Furthermore, in this configuration, the inclination angle θ3 is set to 45° or less. This makes it possible to utilize sound reverberation between the pair of side surfaces 232, 233 to suppress a drop in sound pressure. Furthermore, in this configuration, the inclination angle θ3 is set to 45° or less. Therefore, the effect of sound reverberation between the desk on which the electronic device 1 is placed, the lap, or the like, and the bottom surface 231, and the effect of sound reverberation between the pair of side surfaces 232, 233 based on the inclination angle θ2 can be greatly enhanced by the effect of sound reverberation based on the inclination angle θ3.

[0101] The outer surface 22 includes a right outer surface 22A located outside one longitudinal end of the keyboard 4, and a left outer surface 22B located outside the other longitudinal end of the keyboard 4 and facing away from the right outer surface 22A. The recess 23 includes a recess 23A that opens to the right outer surface 22A, and a recess 23B that opens to the left outer surface 22B. The speaker unit 30 includes a speaker unit 31 that faces at least a part of the back surface 231A of the bottom surface 231 of the recess 23A in which the through-hole 23c is formed, and a speaker unit 32 that faces at least a part of the back surface of the bottom surface 231 of the recess 23B in which the through-hole 23c is formed.

[0102] With this configuration, the sound pressure and quality of the sound emitted by the speaker units 31, 32 can be maintained at a good level in a 360-degree direction around the electronic device 1 when viewing the housing 2 from a direction perpendicular to the outer surface 21 (Z direction).

[0103] The electronic device 1 further includes speaker boxes 41 and 42 that are arranged inside the housing 2 and in which the speaker units 31 and 32 are mounted, respectively.

[0104] This configuration can prevent the sounds emitted from the front and rear of the speaker units 31 and 32 from canceling each other out, thereby improving the sound pressure and quality of the sounds emitted by the speaker units 31 and 32.

[0105] In the first embodiment, the recess 23 has a bottom surface 231 and a pair of side surfaces 232, 233. However, the configuration of the recess 23 is not limited to this. For example, the recess 23 may have a rectangular bottom surface in a plan view and four side surfaces extending from all four sides of the rectangular bottom surface. Furthermore, for example, at least a portion of the surface constituting the recess 23 may be curved. For example, the recess 23 may be constituted by a spherical surface.

[0106] In the first embodiment, the recesses 23A and 23B are formed at the end opposite the hinge portion 7 in the depth direction (Y direction) of the housing 2, and at both ends in the width direction (X direction) of the housing 2. However, the recesses 23A and 23B may be formed at positions other than those mentioned above.

[0107] For example, the recesses 23A and 23B may be formed at the end on the hinge portion 7 side in the depth direction (Y direction), or may be formed at the center of the housing 2 in the depth direction (Y direction).

[0108] Furthermore, for example, the position of the recess 23A in the depth direction (Y direction) may be different from the position of the recess 23B in the depth direction (Y direction).

[0109] Furthermore, for example, recesses 23A and 23B may be formed in the center of outer surface 21 of housing 2, rather than in peripheral edge portion 21A of outer surface 21 of housing 2. In this case, recesses 23A and 23B each have opening 23a but do not have opening 23b.

[0110] In the first embodiment, recess 23A is open to right outer surface 22A, and recess 23B is open to left outer surface 22B. However, recesses 23A and 23B may be open to front outer surface 22C of housing 2 or may be open to rear outer surface 22D of housing 2. Furthermore, as described above, when recesses 23A and 23B are formed in the center of outer surface 21 of housing 2, recesses 23A and 23B are not open to outer surface 22.

[0111] In the first embodiment, two recesses 23, 24 are formed on the outer surface 21 of the housing 2, but the number of recesses is not limited to two. One recess or three or more recesses may be formed on the outer surface 21 of the housing 2. In this case, the speaker unit 30 and the speaker box 40 are arranged corresponding to the respective recesses.

[0112] In the first embodiment, the inclination angle θ2 of the pair of side surfaces 232, 233 is the same as each other, but it does not have to be the same as each other. Similarly, the inclination angle θ3 of the pair of side surfaces 232, 233 is the same as each other, but it does not have to be the same as each other. For example, only one of the pair of side surfaces 232, 233 may be inclined with respect to the virtual plane 25.

[0113] Fig. 9 is a schematic bottom view of the first housing showing a modified recess and its periphery in embodiment 1 according to the present disclosure. Fig. 10 is a schematic right side view of the first housing showing a modified recess and its periphery in embodiment 1 according to the present disclosure. Fig. 11 is a schematic bottom view of the first housing showing a modified recess and its periphery in embodiment 1 according to the present disclosure. Fig. 12 is a schematic right side view of the first housing showing a modified recess and its periphery in embodiment 1 according to the present disclosure.

[0114] In the first embodiment, the bottom surface 231 is inclined toward the right outer surface 22A in a direction approaching the outer surface 11 of the housing 3. The pair of side surfaces 232, 233 are inclined toward the outer surface 21 in a direction increasing the distance between the pair of side surfaces 232, 233, and are also inclined toward the right outer surface 22A in a direction increasing the distance between the pair of side surfaces 232, 233.

[0115] 9 and 10, the bottom surface 231 does not have to be inclined in a direction approaching the outer surface 11 of the housing 2 toward the right outer surface 22A. In this case, the pair of side surfaces 232, 233 may be inclined in a direction increasing the distance between the pair of side surfaces 232, 233 toward the outer surface 21 as shown in Fig. 10, but may not be inclined in a direction increasing the distance between the pair of side surfaces 232, 233 toward the right outer surface 22A as shown in Fig. 9.

[0116] 9 and 10, the recess 23 has a pair of side surfaces 232, 233 that face each other and are each continuous with the outer surface 21. The pair of side surfaces 232, 233 are inclined toward the outer surface 21 in a direction that increases the distance between the pair of side surfaces 232, 233.

[0117] With this configuration, the distance between the pair of side surfaces 232, 233 becomes wider toward the outer surface 21. This allows the sound of the speaker unit 30, which is transmitted to the outside of the electronic device 1 through the opening 23a of the outer surface 21, to be spread in the recess 23. This allows the sound pressure and sound quality of the sound emitted by the speaker unit 30 to be improved.

[0118] 11 and 12, the bottom surface 231 does not have to be inclined in a direction approaching the outer surface 11 of the housing 3 toward the right outer surface 22A. In this case, the pair of side surfaces 232, 233 may be inclined in a direction increasing the distance between the pair of side surfaces 232, 233 toward the right outer surface 22A as shown in FIG. 11, but may not be inclined in a direction increasing the distance between the pair of side surfaces 232, 233 toward the outer surface 21 as shown in FIG.

[0119] 11 and 12, the recess 23 has a pair of side surfaces 232, 233 that face each other and are each continuous with the outer surface 22. The pair of side surfaces 232, 233 are inclined toward the outer surface 22 in a direction that increases the distance between the pair of side surfaces 232, 233.

[0120] With this configuration, the distance between the pair of side surfaces 232, 233 becomes wider toward the outer surface 22. This allows the sound of the speaker unit 30, which is transmitted to the outside of the electronic device 1 through the opening 23b of the outer surface 22, to be spread in the recess 23. Therefore, the sound pressure and sound quality of the sound emitted by the speaker unit 30 can be improved.

[0121] In the first embodiment, the through-hole 23c is formed only in the bottom surface 231 of the recess 23, but the through-hole 23c is not limited to being formed in the bottom surface 231. For example, the through-hole 23c may be formed in both the bottom surface 231 and the pair of side surfaces 232, 233, or may be formed only in the pair of side surfaces 232, 233. When the through-hole 23c is formed in a surface of the recess 23 other than the bottom surface 231, the speaker unit 30 is disposed at a position facing the back surface of the surface of the recess 23 on which the through-hole 23c is formed. For example, when the through-hole 23c is formed in the side surface 232 of the recess 23, the speaker unit 30 is disposed at a position facing the back surface of the side surface 232.

[0122] In the first embodiment, the speaker unit 30 and the speaker box 40 are housed in the internal space of the housing 2. However, the electronic device 1 does not have to be equipped with the speaker box 40. In this case, the speaker unit 30 is housed in the internal space of the housing 2, but the speaker box 40 is not housed therein.

[0123] In the first embodiment, case 10 has outer surface 11, and case 20 has outer surfaces 21 and 22. However, case 10 may have outer surfaces 11 and 22, and case 20 may have outer surface 21.

[0124] In the first embodiment, a notebook personal computer (laptop PC) has been described as an example of the electronic device 1, but the electronic device is not limited to this.

[0125] Although the present invention has been fully described in connection with the preferred embodiments with reference to the accompanying drawings, various changes and modifications will be apparent to those skilled in the art, and it is to be understood that such changes and modifications are included within the scope of the present invention as defined by the appended claims unless they depart therefrom.
