Embodiments for Carrying Out the Invention

[0054] An electronic device according to an example of this embodiment will be described. The electronic device in this embodiment is a peripheral device related to an information processing device such as a smartphone. Note that the information processing device is not limited to a smartphone, and may be any type of information processing device such as a portable or stationary game device, a mobile phone, a tablet terminal, a personal computer, or a wearable terminal. The electronic device is, for example, a portable electronic device that is used in a situation where it is carried by a user together with a portable information processing device. The electronic device, for example, communicates with the information processing device, transmits information indicating an operation performed on the electronic device to the information processing device, or transmits information detected in the electronic device to the information processing device. In addition, the electronic device notifies the user by vibrating, lighting up, or outputting sound. For example, the electronic device notifies the user according to an operation performed on the electronic device, notifies the user according to information detected by the electronic device, or notifies the user according to an instruction from the information processing device. Note that in this embodiment, an electronic device having the above functions will be described as an example, but the electronic device may have any function.

[0055] [1. External Configuration of the Electronic Device] First, the external configuration of the electronic device will be described. FIG. 1 is a four-sided view showing an example of the electronic device. In FIG. 1, (a) is a plan view, (b) is a bottom view, (c) is a rear view, and (d) is a front view.

[0056] As shown in Fig. 1, electronic device 1 includes a housing 2. Housing 2 has a shape having a top surface and a bottom surface. In this embodiment, the direction from the bottom surface to the top surface (more specifically, the direction from the center of the bottom surface to the center of the top surface) is defined as the upward direction (i.e., the positive z-axis direction shown in Fig. 1), and the direction opposite to the upward direction is defined as the downward direction (i.e., the negative z-axis direction shown in Fig. 1).

[0057] FIG. 2 is a diagram illustrating an example of each part of the housing 2. In FIG. 2, (a) is a rear view, and (b) is a front view. As shown in FIG. 2, the housing 2 has a side portion (the portion indicated by diagonal lines in FIG. 2) between the top surface and the bottom surface. If the housing 2 does not have an edge that forms a boundary between the top surface or bottom surface and the side surface, the boundary between the top surface or bottom surface and the side surface may be determined, for example, as follows. That is, the boundary between the top surface and the side surface is a line formed by positions where the angle formed between the normal to the housing 2 and the upward direction is a predetermined first angle, and the side surface is a portion where this angle is within a predetermined range equal to or greater than the first angle. Furthermore, the boundary between the bottom surface and the side surface is a line formed by positions where the angle formed between the normal to the housing 2 and the downward direction is a predetermined second angle, and the side surface is a portion where this angle is within a predetermined range equal to or greater than the second angle. The first angle and the second angle may be the same or different.

[0058] Terminals 5 are provided on the side surfaces of the housing 2 (see FIG. 1). In this embodiment, the direction perpendicular to the up-down direction, from the center of the housing 2 to the terminals 5, is defined as the front direction (i.e., the negative y-axis direction shown in FIG. 1), and the direction opposite to the front direction is defined as the rear direction (i.e., the positive y-axis direction shown in FIG. 1). In other words, the terminals 5 are provided at the front end of the housing 2. Furthermore, by defining the up-down direction and the front-rear direction as described above, the left direction (i.e., the positive x-axis direction shown in FIG. 1) and the right direction (i.e., the negative x-axis direction shown in FIG. 1) that are perpendicular to the up-down direction and also perpendicular to the front-rear direction are defined.

[0059] In this embodiment, the housing 2 is composed of an upper housing 11 and a lower housing 12 (see FIG. 2). In this embodiment, the upper housing 11 has the above-described top surface, and the lower housing 12 has the above-described bottom surface and side surfaces. That is, the boundary between the top surface and the side surfaces becomes the boundary between the upper housing 11 and the lower housing 12. Note that the position of the boundary between the upper housing 11 and the lower housing 12 is arbitrary. For example, in other embodiments, the upper housing may have a part or all of the side surfaces.

[0060] As shown in FIG. 1, the housing 2 is circular when viewed from above. Here, the "circular shape" means a shape whose appearance generally looks like a circle. The circular shape may be a perfect circle, or a shape having a missing part with respect to the perfect circle and / or a protruding part with respect to the perfect circle. The circular shape may also mean a shape in which a part of its outer periphery is not an arc. Further, the circular shape may also mean a shape in which the perfect circle is slightly distorted.

[0061] Also, it can be said that the housing 2 has a shape formed by a curve that bulges outward when viewed from above. For example, when viewed from above, the housing 2 may have a shape other than the above-described circular shape, such as an elliptical shape or an oval shape (see "(Modification Example Regarding the Shape of the Housing)" described later).

[0062] As shown in FIG. 1, the housing 2 has a shape in which the length in the vertical direction is shorter than the length in the direction perpendicular to the vertical direction. In the present embodiment, the housing 2 is circular when viewed from above, and the housing 2 has a shape in which the length in the vertical direction is shorter than the length in any direction perpendicular to the vertical direction. Further, in the present embodiment, the housing 2 has a length (i.e., thickness) in the vertical direction of 21 [mm], and a length (i.e., the diameter of the circular shape when viewed from above) in the direction perpendicular to the vertical direction of 65 [mm]. Thus, it can be said that the housing 2 in the present embodiment is flat. For example, a shape in which the length in the vertical direction is half or less of the length in the direction perpendicular to the vertical direction can be said to be flat. In other embodiments, the housing may have a shape that cannot be said to be flat, as long as the length in the vertical direction is shorter than the length in the direction perpendicular to the vertical direction.

[0063] In the present embodiment, the top surface of the housing 2 has a shape that bulges upward (see FIG. 1). More specifically, in the present embodiment, the top surface of the housing 2 has a shape in which the cross-sectional shape parallel to the vertical direction is convex upward. Also, when the internal region of the housing 2 in the electronic device 1 is cut by a plane perpendicular to the vertical direction, the cross-sectional area becomes smaller as the plane goes upward from the position of the plane where the cross-sectional area is the largest. Note that the "shape that bulges upward" is not limited to the above-described shape, and refers to a shape in which a portion other than the outer edge of the top surface is located above the outer edge of the top surface. For example, when the top surface is convex upward in a portion near the outer edge of the top surface, and is flat or concave downward in a portion near the center of the top surface, but is located above the outer edge of the top surface, the top surface having such a shape can be said to be a "shape that bulges upward". In other embodiments, the top surface of the housing may not have a shape that bulges upward, and may be, for example, flat or concave downward.

[0064] In addition, in the present embodiment, the bottom surface of the housing 2 has a shape that bulges downward (see FIG. 1). That is, the bottom surface of the housing 2 has a shape in which the cross-sectional shape parallel to the vertical direction is convex downward. Further, when the internal region of the housing 2 in the electronic device 1 is cut by a plane perpendicular to the vertical direction, the cross-sectional area becomes smaller as the plane goes downward from the position of the plane where the cross-sectional area is the largest. In other embodiments, the bottom surface of the housing may be a flat surface or a shape that is recessed upward.

[0065] FIG. 3 is a diagram showing an example of how the user holds the electronic device 1. As shown in FIG. 3, in the present embodiment, the housing 2 is sized such that the user can hold the entire housing 2 with one hand. Thus, the electronic device 1 in the present embodiment is a portable (which can also be said to be a portable type) device that the user can hold with one hand. For example, it can be said that a housing having a length in the left-right direction and the front-rear direction of 100 [mm] or less is sized such that the user can hold the entire housing with one hand.

[0066] As shown in FIG. 1, the electronic device 1 includes a top surface button 3. The top surface button 3 is an example of an input unit for receiving an operation input by the user, and more specifically, is an input unit of a type that the user can press. The top surface button 3 is provided on the top surface of the housing 2. Specifically, a hole is formed in the top surface of the housing 2, and the top surface button 3 is provided such that a part of the top surface button 3 is exposed from the hole. In the present specification, "a member is exposed" means that the member (which may be a part thereof) is visible from the outside of the electronic device 1. Note that "a member is exposed" includes both a mode in which the member is provided to protrude from the housing and a mode in which the member is provided without protruding from the housing. In the present specification, the surface of the top surface button 3 that is exposed from the above hole is referred to as the "exposed surface". In other embodiments, the top surface of the housing and the exposed surface of the top surface button may be integrally formed of, for example, a material having elasticity.

[0067] In this embodiment, the above-described hole is circular, and the exposed surface of the top surface button 3 is circular. In this embodiment, the exposed surface of the top surface button 3 is larger than the exposed surface of the side surface button 4, which will be described later. Further, in this embodiment, the top surface button 3 is provided at the center of the housing 2 when viewed from above. More specifically, the top surface button 3 is provided such that the center of the housing 2 and the center of the top surface button 3 coincide (or are close to each other) when viewed from above. Also, the top surface button 3 is provided at the upper end of the housing 2. As shown in FIG. 1, in a state where the top surface button 3 is not pressed, the top surface button 3 protrudes upward from the housing 2. Although details will be described later, the top surface button 3 is movable downward in response to the exposed surface being pressed downward.

[0068] In this embodiment, the top surface button 3 is made of a material having light transmissibility. Note that the "material having light transmissibility" means a material that transmits light, and may be a transparent material (that is, a material through which the shape of an object on the other side of the material can be clearly recognized) or a translucent material (that is, a material through which the shape of an object on the other side of the material cannot be clearly recognized). Also, although details will be described later, a top surface light-emitting portion (that is, the top surface light-emitting portion 42 shown in FIG. 4) is provided inside the housing 2 at a position closer to the inside of the housing 2 than the top surface button 3. By the light from the top surface light-emitting portion passing through the top surface button 3 and being emitted, the top surface button 3 can be made to appear to be glowing. Note that the detailed configuration of the top surface button 3 will be described later.

[0069] As shown in FIG. 1, the electronic device 1 includes a side button 4. The side button 4 is an example of an input unit for receiving an operation input by the user, and more specifically, is an input unit of a type that can be pressed by the user. The side button 4 is provided on the side surface portion of the housing 2. Specifically, a hole (i.e., the hole 2b shown in FIG. 8) is formed in the side surface portion of the housing 2, and the side button 4 is provided such that a part of the side button 4 is exposed from the hole. The above-described hole has a horizontally long shape, and the portion of the side button 4 exposed from the housing 2 (i.e., the exposed surface) has a horizontally long shape (see FIG. 1). Further, in the present embodiment, the side button 4 is provided near the center of the housing 2 in the vertical direction. As shown in FIG. 1, in a state where the side button 4 is not pressed, the side button 4 protrudes rearward from the housing 2. Although details will be described later, the side button 4 is movable forward in response to the exposed surface being pressed forward.

[0070] As shown in FIG. 1, in the present embodiment, the side button 4 is provided at the rear end of the side surface portion of the housing 2. That is, the side button 4 and the terminal 5 are provided at positions symmetric with respect to the center of the housing 2 when viewed from above. According to this, when the user holds the electronic device 1 so as to operate the top surface button 3 and the side button 4 (see FIG. 3), it is difficult for the user's hand to cover the terminal, so that the electronic device 1 can be easily held even when a cord or the like is connected to the terminal.

[0071] In the present embodiment, a hole is formed in the exposed surface of the side button 4, and a light guide portion 23 described later is exposed from the hole (see FIG. 1). Although details will be described later, in the present embodiment, a side surface light emitting portion (i.e., the side surface light emitting portion 224 shown in FIG. 15) is provided inside the housing 2, and the light from the side surface light emitting portion is emitted through the light guide portion 23 so that the light guide portion 23 can appear to be lit. Note that the detailed configuration of the side button 4 will be described later.

[0072] Terminal 5 is a terminal for electrically connecting the electronic device 1 to another device. In the present embodiment, terminal 5 is a USB connector (more specifically, a female connector of USB Type-C). Terminal 5 may be used for the electronic device 1 to receive power supply from another device, or may be used for the electronic device 1 to communicate with another device. Although details will be described later, in the present embodiment, the electronic device 1 includes a rechargeable battery 27 (see FIG. 4), and the rechargeable battery 27 can be charged by the power supplied through terminal 5. From the above, terminal 5 in the present embodiment can be called a charging terminal. Note that the charging terminal means a terminal through which charging can be performed, and is not limited to a terminal that can be used only for charging (for example, a terminal that cannot be used for communication). In other embodiments, the terminal may be one that can be used only for charging.

[0073] Terminal 5 is provided on the side surface portion of the housing 2 (see FIG. 1). Specifically, a hole is formed at the position of the front end on the side surface portion of the housing 2, and terminal 5 is provided such that a part of terminal 5 (for example, a part including pins) is exposed from the housing 2. Note that terminal 5 does not protrude from the housing 2 and is provided inside the housing 2 from the opening portion of the hole.

[0074] In this embodiment, the electronic device 1 includes a bottom button 6. The bottom button 6 is an example of an input unit for receiving an operation input by a user. More specifically, it is an input unit of a type that can be pressed by the user. As shown in FIG. 1, the bottom button 6 is provided on the bottom surface of the housing 2. Specifically, a hole is formed in the bottom surface of the housing 2, and the bottom button 6 is provided such that a part thereof is exposed from the housing 2. In this embodiment, the bottom button 6 functions as a so-called reset button. The bottom button 6 is for receiving an instruction to redo a setting process (for example, pairing) for communication connection between the electronic device 1 and another device that performs wireless communication with the electronic device 1. Therefore, in order to reduce the possibility that the user accidentally presses the bottom button 6, the exposed portion (that is, the exposed surface) of the bottom button 6 is provided at a position recessed with respect to the bottom surface of the housing 2 (that is, so as not to protrude) (see FIG. 1). Also, the area of the exposed surface of the bottom button 6 is smaller than the area of the exposed surface of the top button and the area of the exposed surface of the side button.

[0075] In this embodiment, a strap hole 7 is formed in the housing 2. As shown in FIG. 1, the strap hole 7 is formed in the bottom surface of the housing 2. The strap hole 7 has a shape in which two openings 7a and 7b formed in the bottom surface of the housing 2 are connected by a wall inside the housing 2. By passing a strap through the two openings and tying them, the strap can be attached to the electronic device 1.

[0076] In this embodiment, the strap holes 7 (i.e., the two openings 7a and 7b) are formed on the side of the position of the rear end of the housing 2 (i.e., the rear side) with reference to the center of gravity position of the electronic device 1 (here, it is assumed to be a position near the center of the housing 2) (see Fig. 1). According to this, in the state where the user holds the strap attached to the electronic device 1 (that is, the state where the electronic device 1 is suspended), the electronic device 1 assumes a posture in which the side button 4 is on the upper side and the terminal 5 is on the lower side. Here, it is assumed that the electronic device 1 in this embodiment is held in such a way that the user operates the top surface button 3 with the thumb and the side button 4 with the index finger (see Fig. 3). Therefore, when the electronic device 1 assumes the above posture, the user can hold the suspended electronic device 1 as it is (that is, without changing the posture) and hold the electronic device 1 in a convenient way for operation. Thereby, the convenience of the electronic device 1 can be improved.

[0077] In addition, in other embodiments, the strap holes may be formed at arbitrary positions. For example, in other embodiments, the strap holes may be formed on the side surface portion of the housing. Even when the strap holes are formed on the side surface portion, when the strap holes are formed on the side of the position of the rear end of the housing 2 with reference to the center of gravity position of the electronic device 1, the same effects as in this embodiment can be achieved. Further, in other embodiments, the strap holes may not be formed.

[0078] In this embodiment, a sound hole 2a is formed in the housing 2. As shown in Fig. 1, the sound hole 2a is formed on the side surface portion of the housing 2. Although details will be described later, a speaker is provided inside the housing 2, and the sound hole 2a is formed at a position near the speaker. In this embodiment, the sound hole 2a is formed at a position in front of the center of the housing 2 (see Fig. 1).

[0079] [2. Internal Configuration of Electronic Device 1] Next, the internal configuration of the electronic device 1 will be described. Fig. 4 is an exploded perspective view showing an example of the internal configuration of the electronic device 1. Fig. 5 is an enlarged view of a portion of Fig. 4, and is an exploded perspective view showing components provided below the rechargeable battery 27 in the internal configuration shown in Fig. 4. Figs. 6 and 7 are cross-sectional views showing an example of the internal configuration of the electronic device 1. The cross-sectional view shown in Fig. 6 is a cross-section parallel to the vertical direction, and shows a cross-section passing through the center of the housing 2 and the position of the sound hole 2a. Fig. 7 is a cross-sectional view of the cross-section on the reference plane as seen from above.

[0080] Here, the reference plane is one of the planes that is perpendicular to the vertical direction and intersects with the rechargeable battery 27 included in the electronic device 1. In this embodiment, the reference plane is the plane that is perpendicular to the vertical direction and intersects with the rechargeable battery 27 included in the electronic device 1, and that is the plane where the cross-sectional area of the space inside the housing 2 is largest (see the dashed-dotted line in FIG. 6 ). Note that this cross-sectional area refers to the cross-sectional area of the internal space of the housing 2 when no components are placed inside the housing 2, and refers to a cross-sectional area that is not affected by the presence or absence of components inside the housing 2. The reference plane is defined to explain the placement of each component of the electronic device 1, and is not an actual component included in the electronic device 1. Furthermore, it is not necessary for any components to be placed along the entire reference plane.

[0081] The reference plane is not limited to the plane at which the cross-sectional area is greatest, but may be any plane that is perpendicular to the up-down direction and intersects with the rechargeable battery. For example, in this embodiment, the reference plane intersects with a side surface of the housing, but in other embodiments, it may not intersect with the side surface. In other embodiments, if the plane at which the cross-sectional area is greatest does not intersect with the rechargeable battery, the reference plane may be a plane different from the plane at which the cross-sectional area is greatest. Even if the plane at which the cross-sectional area is greatest intersects with the rechargeable battery, the reference plane may be a plane different from the plane at which the cross-sectional area is greatest.

[0082] (Side button) First, the above-described side button 4 will be described. A part of the side button 4 is provided outside the housing 2, and the other part is provided inside the housing 2. FIG. 8 is an exploded perspective view of the side button 4. In addition to the side button 4, FIG. 8 shows a part of the housing 2 and the guide portion 21. As shown in FIGS. 4, 5, and 8, the side button 4 includes a side key top 22, a light guide portion 23, and a biasing portion 24.

[0083] The side key top 22 has a plate-shaped portion 101, a button portion 102, a stopper 103, a protruding portion 104, and a shaft portion 105. The plate-shaped portion 101 has a plate-shaped shape provided parallel to a plane perpendicular to the front-rear direction (i.e., the xz plane in FIG. 8). The plate-shaped portion 101 is disposed inside the housing 2, and the size of the plate-shaped portion 101 when viewed from the front-rear direction is larger than the hole 2b provided in the side surface portion of the housing 2 when viewed from the front-rear direction. The button portion 102 is provided so as to protrude rearward through the hole 2b from the rear surface of the plate-shaped portion 101. The rear surface of the button portion 102 is the above-described exposed surface. When the side button 4 is not pressed, the rear surface of the plate-shaped portion 101 contacts the inside of the housing 2, and the button portion 102 protrudes from the hole.

[0084] The stopper 103 is provided so as to protrude forward from the front surface of the plate-like portion 101. In the present embodiment, the side key top 22 has two stoppers 103. One stopper 103 is provided at the upper right portion on the front surface of the plate-like portion 101, and the other stopper 103 is provided at the upper left portion on the front surface of the plate-like portion 101. Each stopper 103 has a protruding portion that protrudes upward at a position behind the front end of the stopper 103. In a state where the side button 4 is pressed by a predetermined amount from the state where it is not pressed, the protruding portion of each stopper 103 abuts on an upper substrate 40 (specifically, the side portion on the rear side of the upper substrate 40) described later. As a result, the side key top 22 does not move forward from the state where each stopper 103 abuts on the upper substrate 40. In this way, the stopper 103 can suppress the application of an excessive load to the side input detection unit 25 described later when the side button 4 is pressed. Further, in the present embodiment, by providing the two stoppers 103 on the left and right, even when either the right side or the left side of the side button 4 is pressed, at least one of the protruding portions of each stopper 103 abuts on the upper substrate 40. As a result, it is possible to more reliably suppress the application of an excessive load to the side input detection unit 25.

[0085] The shaft portion 105 is provided on the front surface of the plate-like portion 101 near the central portion in the left-right direction (which can also be said to be the position between the two stoppers 103). The shaft portion 105 is provided so as to protrude forward from the front surface of the plate-like portion 101 (see FIG. 5). The protruding portion 104 is provided above the shaft portion 105 and is provided so as to protrude forward from the front surface of the plate-like portion 101.

[0086] The electronic device 1 also includes a guide portion 21 inside the housing 2. The guide portion 21 is provided in front of the side keytop 22 and is fixed to the lower housing 12, for example, by screws. The guide portion 21 has a bottom portion 111 that is parallel to the horizontal direction (i.e., a direction perpendicular to the up-down direction) and wall portions 112 to 115 that extend vertically upward from the bottom portion 111. In this embodiment, the upper surface of the bottom portion 111 contacts the lower end of the shaft portion 105. A portion of the stopper 103 (specifically, a portion forward of the protruding portion) contacts the lower surface of the upper substrate 40. In this manner, the guide portion 21 and the upper substrate 40 restrict the vertical movement of the side keytop 22. Two of the walls 112 to 115, the wall portions 112 and 113, are provided on both the left and right sides of the shaft portion 105 of the side keytop 22, extending in the front-rear direction along the shaft portion 105. That is, the shaft 105 is inserted between these two walls 112 and 113. This restricts left-right movement of the side keytop 22. As described above, the side keytop 22 is restricted from moving up and down and left and right, but is movable in the front-rear direction.

[0087] Further, the biasing portion 24 is provided to extend in the front-rear direction in a state where the rear end of the biasing portion 24 contacts the front surface of the plate-like portion 101 of the side key top 22 directly below one of the stoppers 103 (here, the right stopper 103). In the present embodiment, the biasing portion 24 is a spring (more specifically, a coil spring), but any material having elasticity may be used. Further, a shaft extending forward from the front surface is provided on the front surface of the plate-like portion 101. The biasing portion 24 is arranged in a state where the above shaft is inserted inside the coil spring. Two of the four wall portions 112 to 115 of the guide portion 21, i.e., the wall portions 113 and 114, are provided on both the left and right sides of the biasing portion 24 to extend in the front-rear direction along the biasing portion 24. Therefore, the biasing portion 24 is positioned in the left-right direction by the above shaft and the two wall portions 113 and 114, and is positioned in the up-down direction by the above shaft, the bottom portion 111, and the stopper 103. Further, among the four wall portions 112 to 115, the wall portion 115 extending in the left-right direction is provided to contact the front end of the biasing portion 24 (see the dotted line shown in FIG. 8). Thus, the biasing portion 24 biases the plate-like portion 101 rearward (i.e., the positive y-axis direction shown in FIG. 8; it can also be said to be the direction from the inside to the outside of the housing 2). Therefore, the side key top 22 is biased rearward and protrudes most from the housing 2 when the side button 4 is not pressed, and can move forward when the side button 4 is pressed.

[0088] As described above, the side button 4, which is an example of the input portion, has a key top (i.e., the side key top 22) that can be pressed in the pressing direction from the outside to the inside of the housing 2 (for example, the front direction), and a biasing portion 24 that is provided inside the housing 2 rather than the key top and biases the key top in the direction opposite to the pressing direction. Thus, in the present embodiment, the side button 4 has a configuration for applying a force to push back the pressed key top inside the housing 2.

[0089] In addition, the electronic device 1 includes a side input detection unit 25 that detects depression of the side button 4 inside the housing 2 (see FIG. 4). The side input detection unit 25 is an electronic component (for example, a switch) that converts an input (specifically, a depression input) made to the side button 4 into a signal. The side input detection unit 25 is provided in front of the protruding portion 104 of the side key top 22. In the present embodiment, the side input detection unit 25 is provided on the upper substrate 40 described later. When the side button 4 is depressed, as a result of the protruding portion 104 moving forward, the side input detection unit 25 is depressed. The side input detection unit 25 detects that the side button 4 has been depressed by detecting that it has been depressed by the protruding portion 104.

[0090] In the present embodiment, the guide portion 21 is provided above (more specifically, directly above) the strap holes 7 described above. That is, the bottom portion 111 of the guide portion 21 is provided at the back of the two openings 7a and 7b when viewed from the outside of the housing 2, and the lower surface of the bottom portion 111 becomes the bottom of the openings. That is, in the present embodiment, it can be said that the guide portion 21 is a bottom forming portion that forms the bottom of the opening. When the user inserts the string of the strap into one of the openings 7a and 7b, the string hits the bottom forming portion and is guided to the other of the openings 7a and 7b, so that the user can easily take out the string from the other of the openings 7a and 7b, and it becomes easier to attach the strap to the electronic device 1. In other embodiments, the bottom of the opening may be configured by the housing instead of being configured by the bottom forming portion (that is, the guide portion 21).

[0091] Note that "the first component is provided above the second component" means that the first component is located above the second component and is provided in a position where at least a portion of the first component appears to overlap at least a portion of the second component when viewed from above. "The first component is provided above the second component" does not necessarily mean that the first component is provided so that the entire first component overlaps the second component when viewed from above. Furthermore, "the first component is provided directly above the second component" means that the first component is provided above the second component with no other components provided between the first and second components.

[0092] As described above, the guide portion 21 has a surface (specifically, the rear surface of the wall portion 115) facing the opposite side to the pressing direction, and the urging portion 24 is sandwiched between this surface and the side keytop 22, thereby urging the side keytop 22 in the opposite direction to the pressing direction. In other words, the guide portion 21 has the function of pressing the urging portion 24 in addition to functioning as the bottom of the strap hole 7. By giving the guide portion 21 multiple functions in this way, the number of parts inside the housing 2 can be reduced, which saves space inside the housing 2 and makes it easier to manufacture the electronic device 1.

[0093] The light guide 23 is a component for guiding light from a side light-emitting portion inside the housing 2 (i.e., the side light-emitting portion 224 shown in FIG. 15 ) to the outside of the housing 2. The light guide 23 is made of a light-transmitting material (more specifically, a transparent material). As shown in FIG. 8 , the light guide 23 has a shape extending in the front-rear direction, and is provided so that its rear end surface is exposed from the hole 4a on the exposed surface of the button portion 102 (see the dotted line in FIG. 8 ). The light guide 23 is fixed to the side keytop 22 by, for example, screwing. In this embodiment, the side light-emitting portion is provided on the upper substrate 40 described later, and the front end surface of the light guide 23 is provided so as to be located near the side light-emitting portion. When the side light-emitting portion emits light, light is incident on the front end surface of the light guide 23, passes through the inside of the light guide 23, and is emitted from the rear end surface. This allows the rear end surface of the light guide 23 provided on the exposed surface to be illuminated.

[0094] (Terminal 5) Next, the above-mentioned terminal 5 will be described. Fig. 9 is a diagram showing an example of the internal configuration of the electronic device 1. Fig. 9 shows the components arranged inside the housing 2, excluding the upper substrate 40 (described later) and the components arranged above it, and the holder 28 (see Fig. 4) (described later). However, in Fig. 9, the arrangement position of the rechargeable battery 27 is indicated by a dashed line. Also, in Fig. 9, only the portion of the housing 2 below the reference plane is shown in order to make the arrangement of the components easier to see.

[0095] The electronic device 1 includes a terminal board 26 fixed to the terminals 5 inside the housing 2 (see FIGS. 5 and 9). In this embodiment, the terminals 5 are fixed by bonding the lower surfaces of the terminals 5 to the upper surfaces of the terminal board 26. Therefore, the terminal board 26 is provided below the terminals 5. The terminal board 26 is fixed to the lower housing 12 by, for example, screws. Although not shown, the terminals 5 are electrically connected to a lower board 32 (described later) via the terminal board 26.

[0096] In this embodiment, the terminal 5 is provided in a position that overlaps with the rechargeable battery 27 when viewed in a direction perpendicular to the up-down direction (i.e., horizontally). This allows the length of the housing 2 in the up-down direction to be shortened, thereby enabling the housing 2 to be made thinner. Note that "provided in an overlapping position" means that it is sufficient that at least a portion of the terminal 5 and at least a portion of the rechargeable battery 27 overlap, and is not limited to the entire terminal 5 overlapping with the rechargeable battery 27, nor is it limited to the entire rechargeable battery 27 overlapping with the terminal 5.

[0097] (rechargeable battery) As shown in Fig. 4, the electronic device 1 includes a rechargeable battery 27. In this embodiment, the rechargeable battery 27 is provided near the center of the housing 2. Specifically, the rechargeable battery 27 is provided so as to overlap the center position of the housing 2 (see Fig. 6). The terminal 5 and side button 4 described above are provided to the side of the rechargeable battery 27.

[0098] In this embodiment, the rechargeable battery 27 has a rectangular parallelepiped shape (see FIG. 4). Specifically, the rechargeable battery 27 has a rectangular parallelepiped shape with some of the sides rounded. The top surface of the rechargeable battery 27 is arranged perpendicular to the vertical direction. This reduces the vertical length of the housing 2, allowing the electronic device 1 to be made thinner.

[0099] In this specification, the axis passing through the center of the rechargeable battery 27 and parallel to the longer side of the sides parallel to the horizontal plane is referred to as the "long axis of the rechargeable battery," and the axis passing through the center and parallel to the shorter side of the sides parallel to the horizontal plane is referred to as the "short axis of the rechargeable battery." Furthermore, the rechargeable battery 27 has a rectangular shape on the reference plane (it can also be said that the cross-sectional shape on the reference plane is rectangular; see FIG. 7). In this specification, the longer side of the four sides of the rechargeable battery 27 on the reference plane may be referred to as the "long side of the rechargeable battery," and the shorter side may be referred to as the "short side of the rechargeable battery." The "long side of the rechargeable battery" and the "short side of the rechargeable battery" may refer to the sides of a rectangular parallelepiped or to a straight line on a surface (specifically, a side surface) of the rectangular parallelepiped. Furthermore, in this specification, the front long side of the long sides of the rechargeable battery 27 on the reference plane may be referred to as the "first long side," and the rear long side may be referred to as the "second long side."

[0100] In this embodiment, the rechargeable battery 27 has a flat shape (see FIGS. 4 and 6). In this embodiment, the rechargeable battery 27 is arranged so that the surface with the largest area is the top surface (and bottom surface). That is, like the housing 2, the rechargeable battery 27 is arranged so that its length in the up-down direction is shorter than its length in the direction perpendicular to the up-down direction. This allows the rechargeable battery 27 to be arranged by efficiently utilizing the space within the housing 2, and the electronic device 1 can be made thinner than when the rechargeable battery 27 is arranged in a different direction.

[0101] In this embodiment, the rechargeable battery 27 is disposed so that its long axis is oblique to the front-to-rear direction, as shown in Fig. 9. On the reference plane, the long side of the rechargeable battery 27 is oblique to the front-to-rear direction (specifically, it faces in a direction midway between the front-to-rear direction and the left-to-right direction), as shown in Fig. 7.

[0102] In this embodiment, a side button 4 is provided at the rear end of the housing 2. The side button 4 (e.g., the shaft 105 of the side button 4) extends from the rear end to a position between the second long side of the rechargeable battery 27 and a portion of the side surface of the housing 2 facing the second long side on the reference plane (see FIG. 7). The rechargeable battery 27 is disposed at an angle relative to the front-to-rear direction as described above, so as not to interfere with the side button 4 (or, alternatively, so as not to overlap when viewed from above). The side button 4 also has components (e.g., the biasing portion 24 and the shaft 105) disposed inside the housing 2, but in this embodiment, these components can be disposed without interfering with the rechargeable battery 27. This allows the electronic device 1 to be made more compact.

[0103] It can also be said that the side button 4 is provided at a position on the side surface of the housing 2 that overlaps with the rechargeable battery 27 when viewed perpendicular to the up-down direction. Note that in other embodiments, the side button may be provided at a position that overlaps with the rechargeable battery when viewed perpendicular to the up-down direction, but does not intersect with the reference plane. As described above, by arranging the side button 4 and the rechargeable battery 27 at approximately the same height, the electronic device 1 can be made thinner.

[0104] In this embodiment, a terminal 5 is provided at the front end position of the housing 2. In the reference plane, the terminal 5 extends from the front end position of the housing 2 to a position between a first long side of the rechargeable battery 27 and a portion of the side surface of the housing 2 that faces the first long side (see FIG. 7). The terminal 5 is provided at a position on the side surface of the housing 2 that overlaps with the rechargeable battery 27 when viewed from a direction perpendicular to the up-down direction. By arranging the rechargeable battery 27 at an angle with respect to the front-to-rear direction as described above, the rechargeable battery 27 is positioned so as not to interfere with the terminal 5.

[0105] Here, if the rechargeable battery 27 is arranged such that the major axis is parallel to the front-rear direction, in order to prevent the rechargeable battery 27 from interfering with the terminal 5 and the side button 4, the length of the rechargeable battery 27 in the major axis direction needs to be made shorter than in this embodiment (alternatively, the housing 2 needs to be enlarged). The dashed-dotted line shown in FIG. 9 indicates an example of the position of the rechargeable battery 27 when the major axis is parallel to the front-rear direction and the rechargeable battery 27 is arranged so as not to interfere with the terminal 5 and the side button 4. Thus, when the rechargeable battery 27 is arranged with the major axis facing the front-rear direction, only a rechargeable battery 27 smaller than this embodiment (the dotted line shown in FIG. 9) can be arranged (alternatively, the miniaturization of the housing 2 cannot be achieved). In contrast, in this embodiment, by arranging the rechargeable battery 27 such that the major axis of the rechargeable battery 27 is inclined with respect to the front-rear direction as described above, the rechargeable battery 27 can be arranged closer to the inner wall of the housing 2, making it easier to arrange a larger rechargeable battery 27.

[0106] It can also be said that in this embodiment, by arranging the rechargeable battery 27 obliquely with respect to the front-rear direction as described above, it becomes easier to secure space for arranging the terminal 5 and the side button 4 within the housing 2. Here, in this embodiment, the cross-sectional shape of the internal space of the housing 2 by a plane that intersects the rechargeable battery 27 and is perpendicular to the vertical direction is circular (see FIG. 7). Therefore, with respect to the region inside the housing 2 at the same height as the rechargeable battery 27, the space for arranging other components between the rechargeable battery 27 and the inner wall of the housing 2 is restricted. Regarding this, in this embodiment, by arranging the rechargeable battery 27 obliquely as described above, it is possible to facilitate the arrangement of the terminal 5 and the side button 4 even in a situation where the above space is restricted.

[0107] In addition, in the present embodiment, the angle formed by the longitudinal axis of the rechargeable battery 27 and the front-rear direction is approximately 55°, but the angle is not limited thereto. As described above, by arranging the rechargeable battery 27 such that the longitudinal axis of the rechargeable battery 27 is inclined with respect to the front-rear direction, at least the above effects can be obtained. For example, when the above angle is in the range of 30° or more and 60° or less, sufficient effects can be obtained.

[0108] In other embodiments, the rechargeable battery may be arranged such that the angle between the longitudinal axis of the rechargeable battery and the front-rear direction is a right angle. Even in such an arrangement, as in the present embodiment, it becomes easier to arrange the rechargeable battery so as not to interfere with the terminals and the side buttons. When the rechargeable battery 27 is arranged obliquely with respect to the front-rear direction as in the present embodiment, compared with the case where the angle between the longitudinal axis of the rechargeable battery 27 and the front-rear direction is a right angle, the space between the terminal 5 and the rechargeable battery 27 (specifically, the space where the speaker described later is arranged), and the space between the side button 4 and the rechargeable battery 27 (specifically, the space where the vibrator described later is arranged) can be widened, so that it becomes easier to arrange components in the housing 2.

[0109] As shown in FIG. 4, the electronic device 1 includes a holder 28. The holder 28 covers at least a portion of the rechargeable battery 27 to protect the rechargeable battery 27. In this embodiment, the holder 28 is provided above the rechargeable battery 27 and covers at least a portion of the top surface (i.e., the upper side) of the rechargeable battery 27. Specifically, the holder 28 has a ceiling portion 121 that is perpendicular to the up-down direction and sidewall portions 122 that extend downward from the ceiling portion 121 (see FIG. 6). The holder 28 is provided in a position where the ceiling portion 121 covers the top surface of the rechargeable battery 27 and the sidewall portions 122 surround the side surfaces of the rechargeable battery 27. As a result, the holder 28 covers the top surface and four side surfaces of the rechargeable battery 27. Note that in other embodiments, the holder may also cover a portion of the bottom surface of the rechargeable battery 27. For example, the holder may further have a protrusion extending horizontally from the lower end of the side wall, and the protrusion may be provided so as to cover part of the bottom surface of the rechargeable battery 27. In this embodiment, since the holder 28 does not cover the bottom surface of the rechargeable battery 27, a lower substrate 32 (described later) can be disposed below the rechargeable battery 27 in close proximity to (or in contact with) the rechargeable battery 27, thereby enabling the electronic device 1 to be made thinner.

[0110] In this embodiment, the rechargeable battery 27 is fixed to the holder 28. While any fixing method may be used, in this embodiment, the top surface of the rechargeable battery 27 is fixed to the holder 28 by adhering the top surface of the rechargeable battery 27 to the lower surface of the ceiling portion 121 of the holder 28 with, for example, double-sided tape. The holder 28 is also fixed to the lower housing 12 with, for example, screws. In this way, the rechargeable battery 27 is fixed to the lower housing 12.

[0111] As shown in FIG. 9 , in this embodiment, the rechargeable battery 27 is large enough that each side between adjacent side surfaces is close to the inner wall of the housing 2 (more specifically, the inner wall of the side surface of the housing 2). As shown in FIG. 7 , in the reference plane, both ends of the long side of the rechargeable battery 27 (i.e., the long side of the rechargeable battery 27 that forms a rectangle in the reference plane) are close to the housing 2. This allows the rechargeable battery 27 to be placed by efficiently utilizing the space within the housing 2, thereby achieving a compact electronic device 1. In this embodiment, the side surfaces of the rechargeable battery 27 are surrounded by the holder 28, and the holder 28 is present between the side surfaces of the rechargeable battery 27 and the side surfaces of the housing 2 (see FIG. 7 ). However, in other embodiments, the holder need not cover the side surfaces of the rechargeable battery, and in this case, the side surfaces of the rechargeable battery may be in contact with the inner wall of the housing. In this embodiment, the holder 28 may be in contact with the inner wall of the side surface of the housing 2, or may not be in contact (although close to the inner wall).

[0112] In this embodiment, recesses 2c are formed on the inner wall of the housing 2 at locations close to or in contact with the corners of the rechargeable battery 27 (see FIG. 9). The holder 28 is disposed with a portion of the holder 28 in the recess 2c. This allows the housing 2 to be made more compact (which also allows a rechargeable battery as large as possible to be accommodated in the housing 2). The holder 28 may or may not be in contact with the recess 2c. In this embodiment, recesses 2c are formed at four locations corresponding to the four vertices on the lower side of the rechargeable battery 27 (see FIG. 9). However, in other embodiments, the number of recesses may be one to three. In other embodiments, recesses may be formed on the inner wall of the housing at least in one of four locations corresponding to the four vertices on the upper side of the rechargeable battery 27. In other embodiments, if the holder does not cover the side surfaces of the rechargeable battery, the rechargeable battery may be disposed with a portion of the rechargeable battery in the recess. In this case, the rechargeable battery may or may not be in contact with the recess.

[0113] (Vibrator and Speaker) As shown in FIGS. 4 and 5, the electronic device 1 includes a vibrator 29. The vibrator 29 vibrates the entire electronic device 1 by its own vibration and is used to notify the user by vibration. The vibrator 29 has a shape with a longitudinal direction (which can also be said to be a shape that is long in one direction), and more specifically, it has a columnar shape extending in the longitudinal direction. The vibrator 29 is provided inside the housing 2 on the side of the rechargeable battery 27 (more specifically, the left rear side) (see FIGS. 6 and 9). As shown in FIG. 9, when viewed from above, the vibrator 29 is provided in a space (for example, the space A surrounded by the dotted line shown in FIG. 9) between the side surface of the rechargeable battery 27 (specifically, the side surface including the second long side) and the portion of the inner wall of the housing 2 (more specifically, the inner wall of the side portion of the housing 2) that faces the side surface. More specifically, the vibrator 29 is provided at a position surrounded by the rechargeable battery 27, the inner wall of the housing 2, and the side button 4 within the above space. In the reference plane, the vibrator 29 is provided at a position between the second long side of the rechargeable battery 27 and the portion of the side portion of the housing 2 that faces the second long side (for example, a position within the above space A) (see FIG. 7). As described above, in this embodiment, by arranging the rechargeable battery 27 obliquely, the above space can be made wider, making it easier to arrange the vibrator 29.

[0114] In this embodiment, the vibrator 29 is arranged such that the longitudinal direction of the vibrator 29 is parallel to the horizontal direction. The vibrator 29 is provided at a position overlapping the rechargeable battery 27 when viewed from the horizontal direction. Thereby, the vibrator 29 can be arranged by efficiently using the space inside the housing 2 (that is, the vibrator 29 is arranged so that the length in the vertical direction becomes shorter), and the housing 2 can be made thinner.

[0115] In addition, in the present embodiment, the vibrator 29 is arranged such that the longitudinal direction of the vibrator 29 and the major axis of the rechargeable battery 27 are in a close orientation (i.e., an angle less than 45°) (see FIG. 9). Note that the speaker may be arranged such that the longitudinal direction of the vibrator 29 and the major axis of the rechargeable battery 27 are parallel. As a result, the vibrator 29 can be arranged by efficiently using the space in the above-described space, and the electronic device 1 can be made smaller than in the case where it is arranged in other orientations. It can also be said that it becomes easier to arrange a larger vibrator.

[0116] The vibrator 29 is fixed to the lower housing 12. Specifically, the lower housing 12 has a frame portion 131 that surrounds the vibrator 29 in the horizontal direction (see FIGS. 5 and 9). The frame portion 131 has a wall that extends upward from the inner wall on the back side of the bottom surface of the lower housing 12, and the vibrator 29 is sandwiched from all four sides by the wall. The vibrator 29 is fixed to the lower housing 12 by being sandwiched by the wall with a certain amount of force applied from the wall.

[0117] The vibrator 29 is also fixed by the holder 28. FIG. 10 is a diagram showing the position of the holder 28 inside the housing 2. Note that in FIG. 10, among the components arranged inside the housing 2, the components arranged above the holder 28 are omitted. Also, in FIG. 10, only the portion of the housing 2 below the reference plane is shown for the purpose of making it easier to view the arrangement of each component.

[0118] As shown in FIG. 10, the holder 28 that covers the rechargeable battery 27 has a first arm portion 123 that extends above the vibrator 29. The first arm portion 123 contacts the upper portion of the vibrator 29 and presses the vibrator 29 from above (see FIG. 6). Therefore, in the vertical direction, the vibrator 29 is also fixed by being sandwiched between the inner wall of the lower housing 12 and the holder 28. As a result, the vibrator 29 can be fixed more firmly to the housing 2. Also, the vibration caused by the vibrator 29 can be more easily transmitted to the housing 2.

[0119] As shown in FIGS. 4 and 5, the electronic device 1 includes a speaker 30. In the present embodiment, the speaker 30 has a flat shape with a wider front and back surfaces compared to other surfaces, and the front and back surfaces are vertically long. The speaker 30 is provided inside the housing 2 on the side of the rechargeable battery 27 (more specifically, the right front side) (see FIGS. 6 and 9). As shown in FIG. 9, when viewed from above, the speaker 30 is provided in a space (for example, space B surrounded by the dotted line shown in FIG. 9) between the side surface of the rechargeable battery 27 (specifically, the side surface including the first long side) and the portion of the inner wall of the housing 2 (more specifically, the inner wall of the side portion of the housing 2) that faces the side surface. More specifically, the speaker 30 is provided at a position surrounded by the rechargeable battery 27, the inner wall of the housing 2, and the terminal 5 within the above space. In the reference plane, the speaker 30 is provided at a position between the first long side of the rechargeable battery 27 and the portion of the side portion of the housing 2 that faces the first long side (see FIG. 7). As described above, in the present embodiment, by arranging the rechargeable battery 27 obliquely, the above space can be widened, making it easier to arrange the speaker 30.

[0120] In the present embodiment, the speaker 30 is arranged such that the longitudinal direction of the speaker 30 and the major axis of the rechargeable battery 27 are in a direction close to each other (specifically, a direction forming an angle less than 45°). Note that the speaker 30 may be arranged such that the longitudinal direction of the speaker 30 and the major axis of the rechargeable battery 27 are parallel. Thereby, the speaker 30 can be arranged by efficiently using the space within the above space, and the miniaturization of the electronic device 1 can be achieved compared to the case where it is arranged in other directions. It can also be said that it becomes easier to arrange a larger speaker.

[0121] Note that the electronic device 1 includes a pedestal 31 (see FIG. 4). The speaker 30 is fixed to the lower housing 12 via the pedestal 31. Specifically, the pedestal 31 is fixed to the inner wall on the back side of the bottom surface of the lower housing 12 by, for example, screwing. The speaker 30 is fixed to the pedestal 31 by being adhered, for example, with double-sided tape.

[0122] In this embodiment, the speaker 30 is also fixed by the holder 28. As shown in FIG. 10, the holder 28, which covers the rechargeable battery 27, has a second arm 124 that extends above the speaker 30. The second arm 124 presses the speaker 30 from above via a buffer material (see FIG. 6). Therefore, the speaker 30 is also fixed by being sandwiched between the base 31 and the holder 28. This allows the speaker 30 to be fixed more firmly to the housing 2.

[0123] As described above, in this embodiment, holder 28, which covers at least a portion of rechargeable battery 27, presses vibrator 29 from above and also presses speaker 30 from above. That is, in this embodiment, it can be said that the members for fixing rechargeable battery 27, vibrator 29, and speaker 30 are integrated. This reduces the number of parts inside housing 2, thereby saving space within housing 2 and facilitating the manufacture of electronic device 1. Note that in this embodiment, holder 28 fixes rechargeable battery 27, vibrator 29, and speaker 30. However, in other embodiments, the holder may fix only rechargeable battery 27, or may fix either vibrator 29 or speaker 30 in addition to rechargeable battery 27. Furthermore, in other embodiments, electronic device 1 may include a component other than holder 30 that presses vibrator 29 from above, or a component other than holder 30 that presses speaker 30 from above.

[0124] As shown in FIG. 6 , in this embodiment, the flat speaker 30 is disposed with its front and back surfaces tilted relative to a horizontal plane. Specifically, the speaker 30 is disposed tilted in the direction of rotation about an axis roughly parallel to the long axis of the rechargeable battery 27 (which can also be said to be parallel to the long side of the rechargeable battery 27 on a reference plane). More specifically, the speaker 30 is tilted so that the side closer to the rechargeable battery 27 is at the bottom and the side farther from the rechargeable battery 27 is at the top. It can also be said that the speaker 30 is tilted so that the side closer to the center of the housing 2 when viewed from above is at the bottom and the side farther from the center is at the top. As a result, compared to when the flat speaker 30 is disposed horizontally without tilting, the width of the speaker 30 in the direction perpendicular to the long axis of the rechargeable battery 27 (i.e., the width of the speaker 30 when viewed from above) can be made smaller, thereby enabling the electronic device 1 to be made more compact. It can also be said that this makes it easier to arrange larger speakers. The tilt direction of the speaker 30 is not limited to the rotation direction around an axis parallel to the major axis of the rechargeable battery 27, but may be the rotation direction around any axis that faces in a direction closer to the major axis than the minor axis of the rechargeable battery 27. In this case, similar to this embodiment, the electronic device can be made smaller. In other embodiments, the flat speaker may be arranged so that the front and back surfaces are parallel to a horizontal plane, or so that the front and back surfaces are perpendicular to the horizontal plane.

[0125] Furthermore, the above-mentioned sound hole 2a is formed in a position on the side surface of the housing 2 near the speaker 30 (see FIG. 6). For example, the sound hole 2a is formed in a position such that the speaker 30 is located between the center of the housing 2 and the sound hole 2a when viewed from above. This makes it easier for sound from the speaker 30 to be transmitted to the outside of the housing 2. Note that in other embodiments, the position of the sound hole is arbitrary, and for example, the sound hole may be formed in the top or bottom surface of the housing near the speaker.

[0126] As described above, in this embodiment, the vibrator 29 and the speaker 30 are disposed at positions where the rechargeable battery 27 is sandwiched between the vibrator 29 and the speaker 30 (see FIG. 9). That is, inside the housing 2, the vibrator 29 is disposed on one side of the rechargeable battery 27, and the speaker 30 is disposed on the other side of the rechargeable battery 27. This allows the vibrator 29 and the speaker 30 to be disposed by efficiently utilizing the space inside the housing 2 other than the rechargeable battery 27, thereby enabling the electronic device 1 to be made more compact. It also makes it easier to dispose a larger vibrator 29 and a larger speaker 30.

[0127] In other embodiments, the vibrator and speaker may be arranged on the same side of the rechargeable battery 27. Furthermore, in other embodiments, the electronic device may include a vibration unit (e.g., a voice coil motor) capable of generating vibrations and sound, instead of including the vibrator 29 and speaker 30. For example, the vibration unit may be arranged in the space where the speaker 30 is arranged (i.e., space B surrounded by the dotted line in FIG. 9).

[0128] In this embodiment, the speaker 30 and the vibrator 29 are provided at positions offset in the front-to-rear direction (see FIG. 9 ). As described above, in this embodiment, the long axis of the rechargeable battery 27 is oblique to the front-to-rear direction. Therefore, on one of the left and right sides of the housing 2 (here, the right side), a space (for example, space B surrounded by a dotted line in FIG. 9 ) is created in front of the center of the housing 2, while on the other side (here, the left side), a space (for example, space A surrounded by a dotted line in FIG. 9 ) is created behind the center of the housing 2. Therefore, by arranging the speaker 30 and the vibrator 29 on the right and left sides of the housing 2 at positions offset in the front-to-rear direction, the speaker 30 and the vibrator 29 can be arranged so as not to interfere with the rechargeable battery 27.

[0129] In this embodiment, the speaker 30 is provided at a position in front of the vibrator 29. The speaker 30 and the sound hole 2a are provided on the front side of the center of the housing 2 (which can also be said to be the side opposite to the side where the side button 4 is provided). Here, in this embodiment, it is assumed that the user holds the electronic device 1 by operating the top surface button 3 with the thumb and the side button 4 with the index finger (see FIG. 3). At this time, when the user holds the electronic device 1 by tilting it so that the front side of the electronic device 1 (i.e., the side where the terminal 5 is provided) approaches the front side as seen by the user, and the rear side of the electronic device 1 (i.e., the side where the side button 4 is provided) moves away from the user to the back side as seen by the user. When the user holds the electronic device 1 as described above, by arranging the speaker 30 and the sound hole 2a on the front side of the center of the housing 2 as in this embodiment, the sound from the speaker 30 can be made easier for the user to hear. In other embodiments, the arrangement of the speaker 30 and the vibrator 29 in this embodiment may be interchanged.

[0130] Also, in this embodiment, the rechargeable battery 27 is provided such that the center of the housing 2 and the center of the rechargeable battery 27 coincide or are close to each other when viewed from above. Thereby, in the housing 2, spaces of approximately the same width can be secured on both sides of the rechargeable battery 27 (that is, the space A and the space B shown in FIG. 9 can be made to have approximately the same width). In other embodiments, the center of the rechargeable battery may be provided at a position different from the center of the housing when viewed from above. In other embodiments, for example, when the volume of the speaker is larger than that of the vibrator, the rechargeable battery may be arranged such that the space B is wider than the space A.

[0131] (Lower substrate) As shown in FIG. 4, the electronic device 1 includes a lower substrate 32. The lower substrate 32 is a substrate on which a control circuit (i.e., a control circuit 221 shown in FIG. 15) that executes control processing in the electronic device 1 is provided. The electronic device 1 also includes an acceleration sensor (i.e., an acceleration sensor 222 shown in FIG. 15) and a connector 141 (see FIG. 9). In this embodiment, the acceleration sensor and connector 141 are provided on the lower substrate 32. The lower substrate 32 is provided below the rechargeable battery 27 (see FIG. 6). The lower substrate 32 is fixed to the lower housing 12 (more specifically, to the inner wall on the back side of the bottom surface of the lower housing 12) by, for example, screws.

[0132] The acceleration sensor is an example of an inertial sensor, and detects acceleration applied to the electronic device 1. In this embodiment, the acceleration sensor is provided on the bottom surface (i.e., the lower surface) of the lower substrate 32. By providing the acceleration sensor on the bottom surface, the distance between the lower substrate 32 and the rechargeable battery 27 arranged above it can be narrowed, thereby saving space. This allows the electronic device 1 to be made thinner. It also prevents contact between the rechargeable battery 27 and the acceleration sensor. Note that in other embodiments, the electronic device may be provided with another type of inertial sensor (for example, an angular velocity sensor) instead of (or in addition to) the acceleration sensor, or may not be provided with an acceleration sensor.

[0133] The connector 141 is for electrically connecting the lower substrate 32 and the rechargeable battery 27. In this embodiment, a cord is connected to the rechargeable battery 27, and the cord extends from a hole 28a formed in the holder 28 to the outside of the holder 28 and is connected to the connector 141. Thereby, the connector 141 is electrically connected to the rechargeable battery 27. Note that the connector 141 is provided at a position different from the portion directly below the rechargeable battery 27 (that is, the portion hidden by the rechargeable battery 27 when viewed from above) on the top surface side (i.e., the upper surface) of the lower substrate 32 (see FIG. 9). That is, the connector 141 is provided at a position where it does not overlap with the rechargeable battery 27 when viewed from above. Thereby, the distance between the lower substrate 32 and the rechargeable battery 27 disposed above it can be narrowed, and the electronic device can be made thinner.

[0134] In this embodiment, no component protruding from the lower substrate 32 is provided in the portion directly below the rechargeable battery 27 on the top surface side of the lower substrate 32 (see FIG. 6). Thereby, the distance between the lower substrate 32 and the rechargeable battery 27 disposed above it can be narrowed, and the electronic device can be made thinner. Note that the lower substrate 32 and the rechargeable battery 27 may be disposed with a gap therebetween, or may be disposed in contact with each other. Further, the lower substrate 32 and the rechargeable battery 27 may be adhered to each other.

[0135] Also, the lower substrate 32 is provided at a position overlapping with the vibrator 29 and the speaker 30 when viewed in the horizontal direction (see FIG. 6). Thereby, the length of the housing 2 in the vertical direction can be shortened, and the housing 2 can be made thinner.

[0136] (Bottom button) The bottom button 6 is provided such that a part of it is exposed from the hole on the bottom surface of the housing 2. In this embodiment, the bottom button 6 has a bottom key top 33 and a bottom key lever 34. The bottom key top 33 has an upper surface and a lower surface, and the lower surface, which is the exposed surface, is provided so as to cover the hole on the bottom surface of the housing 2 from the inside of the housing 2. The bottom key lever 34 has a ceiling portion extending parallel to the horizontal direction and a side wall portion extending downward from the outer periphery of the ceiling portion. The bottom key lever 34 is provided above the bottom key top 33, and the lower surface of the ceiling portion contacts the upper surface of the bottom key top 33. The lower housing 12 has a frame portion 132 extending upward from the inner wall of the lower housing 12 around the above-mentioned hole (see FIG. 5). By this frame portion contacting the side wall portion of the bottom key lever 34, the bottom key lever 34 is fixed in the horizontal direction. Also, in the vertical direction, the bottom key lever 34 is fixed by being sandwiched between the upper lower substrate 32 and the lower lower housing 12.

[0137] A protrusion is provided near the center on the upper surface of the ceiling portion of the bottom key lever 34. A bottom input detection portion (that is, the bottom input detection portion 223 shown in FIG. 15) for detecting the depression of the bottom button 6 is provided at a position directly above the protrusion on the lower surface of the lower substrate 32. In a state where the bottom button 6 is not depressed, the protrusion does not press the bottom input detection portion. On the other hand, when the bottom button 6 is depressed, the bottom key lever 34 elastically deforms, and as a result of the protrusion moving upward, the bottom input detection portion is pressed. The bottom input detection portion detects that the bottom button 6 has been depressed by detecting that it has been pressed by the protrusion.

[0138] (Upper substrate) As shown in FIG. 4, the electronic device 1 includes an upper substrate 40. The upper substrate 40 is provided above the holder 28 inside the housing 2 (see FIG. 6). The upper substrate 40 is fixed to the upper housing 11 (more specifically, the inner wall on the back side of the top surface of the upper housing 11) by, for example, screwing. In the present embodiment, the above-described side input detection unit 25 and the side light-emitting unit (that is, the side light-emitting unit 224 shown in FIG. 15) are provided on the upper substrate 40. The side input detection unit 25 is provided at the rear end of the upper substrate 40 so as to be disposed in front of the protruding portion 104 on the side key top 22 of the side button 4 described above. Further, the side light-emitting unit is provided near the front end of the upper substrate 40 so as to be disposed in the vicinity of the front end of the light guide unit 23 of the side button 4 described above. Note that the side light-emitting unit is, for example, an LED.

[0139] Further, the electronic device 1 includes a top surface input detection unit 41 that detects depression of the top surface button 3, and a top surface light-emitting unit 42. The top surface input detection unit 41 is an electronic component (for example, a switch) that converts an input (specifically, a depression input) performed on the top surface button 3 into a signal. In the present embodiment, the top surface input detection unit 41 is provided directly below the center position on the exposed surface of the top surface button 3 on the upper surface of the upper substrate 40 (see FIG. 12 described later). Thus, by providing the top surface input detection unit 41 on the top surface side surface (that is, the upper surface) of the upper substrate 40, the distance between the bottom surface side surface (that is, the bottom surface; also referred to as the surface on the rechargeable battery 27 side) of the upper substrate 40 and the rechargeable battery 27 can be narrowed, and space can be saved. Thereby, the electronic device 1 can be made thinner.

[0140] In this embodiment, the electronic device 1 includes four top surface light-emitting units 42. The top surface light-emitting units 42 are light sources for illuminating the top surface buttons 3, and are, for example, LEDs. The four top surface light-emitting units 42 are provided on the upper surface of the upper substrate 40, respectively, around the top surface input detection unit 41. By providing the top surface light-emitting units 42 on the top surface of the upper substrate 40 in this manner, light can be emitted to the outside of the housing 2 through the light-transmitting top surface buttons 3. This allows the top surface buttons 3 to glow (or, it can be said, the top surface buttons 3 appear to be glowing). In other embodiments, the number of top surface light-emitting units is arbitrary and is not limited to four. As will be described in detail later, providing multiple top surface light-emitting units 42 allows the exposed surfaces of the top surface buttons 3 to glow evenly.

[0141] The electronic device 1 also includes an antenna (that is, the antenna 225 shown in FIG. 15) for communicating with the information processing device described above. In this embodiment, the antenna is provided on the upper substrate 40.

[0142] As described above, in this embodiment, no components protruding from the upper substrate 40 are provided on the bottom surface (i.e., the lower surface) of the upper substrate 40 in the portion directly above the rechargeable battery 27 (i.e., the portion hidden by the rechargeable battery 27 when viewed from below) (see FIG. 6). This makes it possible to narrow the gap between the bottom surface of the upper substrate 40 and the rechargeable battery 27, thereby enabling the electronic device 1 to be made thinner. Note that, as will be described in detail later, in this embodiment, the lower surface of the upper substrate 40 and the upper surface of the holder 28 are adhered, for example, with double-sided tape. However, in other embodiments, the lower surface of the upper substrate and the upper surface of the holder may not be adhered or may not be in contact with each other.

[0143] In addition, in the present embodiment, the sum of the area of one side of the lower substrate 32 and the area of one side of the upper substrate 40 is larger than the cross-sectional area of the space inside the housing 2 by a plane (in the present embodiment, the reference plane) in a plane perpendicular to the vertical direction when the cross-sectional area of the space inside the housing 2 is the largest. According to this, even when the area of the substrate is so large that the substrate cannot be completely accommodated in the housing 2 when it is a single substrate, each substrate can be accommodated in the housing 2, and the miniaturization of the electronic device 1 can be achieved.

[0144] In addition, in the present embodiment, the above-described speaker 30 and the vibrator 29 are disposed below the upper substrate 40 (see FIG. 6). Therefore, the speaker 30 and the vibrator 29 can be arranged so as to overlap the upper substrate 40 when viewed from above, and the length of the housing 2 in the horizontal direction (that is, the left-right direction or the front-back direction) can be shortened. Thereby, the miniaturization of the electronic device 1 can be achieved.

[0145] (Top surface button 3) With reference to FIGS. 11 and 12 and the like, the detailed configuration of the top surface button 3 will be described. FIG. 11 is an exploded perspective view of the top surface button 3. In FIG. 11, in addition to the top surface button 3, the upper housing 11 is shown. FIG. 12 is a cross-sectional view showing an example of the internal configuration of the electronic device 1. In FIG. 12, the upper substrate 40 and the components above it are shown.

[0146] The top surface button 3 is provided above the upper substrate 40 (see FIG. 12). As shown in FIG. 11, in the present embodiment, the top surface button 3 includes a top surface key top 43, a spacer 44, and a top surface key lever 45. A top surface key lever 45 is provided above the upper substrate 40, a spacer 44 is provided above the top surface key lever 45, and a top surface key top 43 is provided above the spacer 44. A part of the top surface key top 43 is provided so as to protrude from the hole of the upper housing 11.

[0147] As shown in FIG. 12, the top surface keytop 43 has a central portion 151, an outer edge portion 152, and a rising portion 153. The central portion 151 is the portion whose upper surface is exposed from the hole in the upper housing 11, and is a flat plate extending horizontally. The central portion 151 has a circular shape when viewed from above, and is the same size as or slightly smaller than the hole. In this embodiment, the upper surface of the central portion 151 (i.e., the exposed surface) is a curved surface that bulges slightly upward, but it may also be flat.

[0148] The outer edge portion 152 is an outer edge portion of the top surface keytop 43, and is provided around the central portion 151. When viewed from above, the outer edge portion 152 has an annular shape that surrounds the central portion 151. The lower surface of the outer edge portion 152 is provided below the lower surface of the central portion 151.

[0149] Furthermore, the rising portion 153 is a portion between the central portion 151 and the outer edge portion 152. When viewed from above, the rising portion 153 has a circular ring shape surrounding the central portion 151. As shown in FIG. 12 , the rising portion 153 is provided so as to extend in the vertical direction. Specifically, the rising portion 153 extends upward from the inner peripheral portion of the outer edge portion 152, and its upper end is connected to the outer peripheral portion of the central portion 151. Furthermore, the rising portion 153 is located to the side of the opening of the hole in the upper housing 11. As described above, in this embodiment, since the top surface keytop 43 has a rising portion, the top surface keytop 43 is less likely to shift horizontally relative to the housing 2 and is less likely to come off the housing 2. Note that the above-mentioned phrase "extending in the vertical direction" means that the extending direction may have a vertical component, and is not limited to extending parallel to the vertical direction.

[0150] The top surface keytop 43 is entirely made of a light-transmitting material. However, in other embodiments, only a part of the top surface keytop (for example, the center) may be light-transmitting.

[0151] The spacer 44 has a central portion 161, an outer edge portion 162, and a rising portion 163. The central portion 161 is on a flat plate extending in the horizontal direction and is circular when viewed from above. The central portion 161 of the spacer 44 is provided below the central portion 151 of the top surface key top 43. In this embodiment, the lower surface of the central portion 161 of the spacer 44 is arranged at the same height (i.e., the vertical position) as the lower surface of the outer edge portion 152 of the top surface key top 43. Thereby, the thickness of the component composed of the top surface key top 43 and the spacer 44 can be reduced, and the thickness of the top surface button 3 can be reduced. Also, the upper surface of the central portion 161 of the spacer 44 is flat. The spacer 44 has a protruding portion 164 that protrudes downward from the flat portion of the lower surface at the lower surface of the central portion 161. The protruding portion 164 is provided at the center position when viewed from above (which can also be said to be the center of the exposed surface of the top surface key top 43) (see FIG. 12).

[0152] The outer edge portion 162 is the portion of the outer edge of the spacer 44 and is provided around the central portion 161. When viewed from above, the outer edge portion 162 is in an annular shape surrounding the central portion 161. Also, the lower surface of the outer edge portion 162 is provided below the lower surface of the central portion 161. The lower surface of the protruding portion 164 is located above the lower surface of the outer edge portion 162. Thereby, the thickness of the top surface button 3 can be reduced.

[0153] The raised portion 163 is a portion between the central portion 161 and the outer edge portion 162. When viewed from above, the raised portion 163 has a circular ring shape surrounding the central portion 161. As shown in FIG. 12 , the raised portion 163 is provided so as to extend in the vertical direction. That is, the raised portion 163 extends upward from the inner peripheral portion of the outer edge portion 162, and its upper end is connected to the outer peripheral portion of the central portion 161. By providing the raised portion 163 on the spacer 44, the distance between the central portion 161 of the spacer 44 and the upper substrate 40 can be increased. This reduces the possibility that a component (e.g., the top light-emitting unit 42) provided on the upper substrate 40 will hit the central portion 161 via the top key rubber 45 when the top button 3 is pressed. Note that in this embodiment, the raised portion 163 extends diagonally upward from the outer edge portion 162; however, in other embodiments, the raised portion 163 may be provided so as to extend directly upward from the outer edge portion 162.

[0154] Furthermore, the rising portion 163 of the spacer 44 is provided at a position where, when viewed from above, at least a portion of the rising portion 163 overlaps with the rising portion 153 of the top surface keytop 43. It can also be said that the rising portion 163 of the spacer 44 is provided in the vicinity of the rising portion 153 of the top surface keytop 43 (see FIG. 12). This makes it possible to increase the distance between most of the central portion 161 of the spacer 44 and the upper substrate 40, thereby reducing the possibility that components provided on the upper substrate 40 will hit the central portion via the top surface key rubber 45 when the top surface button 3 is pressed.

[0155] The spacer 44 is made of a material that is optically transparent as a whole, but in other embodiments, only a part of the spacer (for example, the center part) may be optically transparent.

[0156] The spacer 44 is fixed to the top surface key top 43. Specifically, the outer edge portion 152 of the top surface key top 43 and the outer edge portion 162 of the spacer 44 are fixed. In the present embodiment, the top surface key top 43 has protrusions 154 on the lower surface of the outer edge portion 152, and holes 44a are formed at the positions of the protrusions 154 in the outer edge portion 162 of the spacer 44 (see FIG. 11). In the present embodiment, there are three protrusions 154 and holes 44a respectively, but the number of protrusions 154 and holes 44a provided is arbitrary. By performing thermal caulking in a state where the protrusions 154 are inserted into the holes 44a, the top surface key top 43 and the spacer 44 are fixed.

[0157] As described above, in the present embodiment, in a state where the top surface key top 43 is not pressed, the outer edge portion 162 of the spacer 44 contacts the outer edge portion 152 of the top surface key top 43 (see FIG. 12). According to this, since the spacer 44 moves downward immediately in response to the start of pressing of the top surface key top 43, it is possible to easily detect the pressing of the top surface button 3. In the present embodiment, whether the top surface key top 43 is not pressed or the top surface key top 43 is pressed, the outer edge portion 162 of the spacer 44 contacts the outer edge portion 152 of the top surface key top 43. However, in other embodiments, in a state where the top surface key top 43 is not pressed, the outer edge portion 162 of the spacer 44 does not contact the outer edge portion 152 of the top surface key top 43, and in a state where the top surface key top 43 is pressed, the outer edge portion 162 of the spacer 44 may be configured to contact the outer edge portion 152 of the top surface key top 43.

[0158] Also, in other embodiments, the outer edge portion 162 of the spacer 44 and the outer edge portion 152 of the top surface key top 43 may be connected via an intermediate member. For example, the electronic device may include a cushioning material sandwiched between the upper surface of the outer edge portion 162 of the spacer 44 and the lower surface of the outer edge portion 152 of the top surface key top 43 as an intermediate member. Even in this case, the spacer 44 can be moved downward in response to the pressing on the top surface key top 43.

[0159] Note that a frame portion 171 extending downward is provided on the inner wall of the upper housing 11 (see FIG. 11). The frame portion 171 is provided so as to surround the outer edge portion 152 of the top surface key top 43 (see FIG. 12). The outer edge portion 152 of the top surface key top 43 when viewed from above is generally circular, but has a protruding portion 155 that protrudes outside the circle at a part thereof. A concave portion 172 into which the protruding portion 155 can be fitted is provided in the frame portion 171, and the top surface key top 43 is arranged such that the protruding portion 155 is fitted into the concave portion 172 in the horizontal direction. Thereby, the top surface key top 43 (and the spacer 44) is positioned in the horizontal direction and is configured to be movable in the vertical direction. Note that in the present embodiment, the number of the protruding portions 155 and the concave portions 172 is four, but may be any number of one or more.

[0160] The top surface key rubber 45 has a bottom portion 181 and a side wall portion 182 (see FIG. 12). The bottom portion 181 is provided so as to extend in the horizontal direction below the spacer 44. The side wall portion 182 is annular and is provided so as to extend upward from the outer periphery of the bottom portion 181. The upper end of the side wall portion 182 contacts the inner wall of the upper housing 11 (more specifically, the portion around the hole in the inner wall) or extends to the vicinity of the inner wall. By the inner side of the side wall portion 182 contacting the outside of the frame portion 171 of the upper housing 11, the top surface key rubber 45 is positioned in the horizontal direction. Further, a part of the lower surface of the bottom portion 181 contacts the upper surface of the upper substrate 40, and a part of the upper surface of the bottom portion 181 contacts the lower end of the frame portion 171 of the upper housing 11, whereby the top surface key rubber 45 is positioned in the vertical direction.

[0161] The top surface key rubber 45 is made of a material having light transmissivity and elasticity. Note that in the present embodiment, the top surface key rubber 45 is made of a material having light transmissivity as a whole. However, in other embodiments, the top surface key rubber may have light transmissivity only in a part thereof (for example, the bottom portion).

[0162] As shown in FIG. 12, in the bottom portion 181, the portion above the top surface input detection portion 41 and the top surface light emitting portion 42 provided on the upper substrate 40 protrudes upward (it can also be said that the lower surface of the bottom portion 181 is recessed upward). Thereby, among the bottom portion 181, portions other than the portion above the top surface input detection portion 41 and the top surface light emitting portion 42 can be arranged at positions in contact with or close to the upper substrate 40, and the thickness reduction of the top surface button 3 can be achieved.

[0163] Further, on the upper surface of the bottom portion 181, at a position directly below the protruding portion 164 of the lower surface of the spacer 44, an upward protruding upper protruding portion 183 is provided (see FIG. 12). In the present embodiment, in a state where the top surface key top 43 is not pressed, the upper protruding portion 183 contacts the lower surface of the protruding portion 164 of the spacer 44. Further, on the lower surface of the bottom portion 181, at a position below the protruding portion 164 of the spacer 44, a downward protruding lower protruding portion 184 is provided (see FIG. 12). In a state where the top surface button 3 is not pressed, the lower surface of the lower protruding portion 184 may or may not be in contact with the top surface input detection portion 41.

[0164] In the present embodiment, at least a part of the upper surface (that is, the upper protruding portion 183) of the portion of the top surface key lever 45 located directly above the top surface input detection portion 41 is located above the upper surface of the portion located directly above the top surface light emitting portion 42. According to this, when the top surface button 3 is pressed, the possibility that the spacer 44 hits the portion of the top surface key lever 45 located directly above the top surface light emitting portion 42 can be reduced, so that the possibility that the spacer 44 hits the top surface light emitting portion 42 via the top surface key lever 45 can be reduced.

[0165] Further, in the present embodiment, the top surface light emitting portion 42 is provided on the upper substrate 40 at a position excluding the portion directly below the protruding portion 164 in the central portion 161 of the spacer 44 (see FIG. 12). Also by this, the possibility that the spacer 44 hits the top surface light emitting portion 42 via the top surface key lever 45 can be reduced.

[0166] With the above configuration, the top surface button 3 can move in the up and down direction, and the top surface input detection unit 41 can detect a press input on the top surface button 3. Specifically, when the top surface button 3 is not pressed, the top surface keytop 43 protrudes to the maximum extent from the upper housing 11. That is, the upper surface of the outer edge 152 of the top surface keytop 43 comes into contact with the inner wall of the upper housing 11. Note that in this embodiment, the upper surface of the outer edge 152 of the top surface keytop 43 comes into contact with the inner wall of the upper housing 11 via a buffer material, but in other embodiments, the upper surface of the outer edge 152 of the top surface keytop 43 may come into direct contact with the inner wall of the upper housing 11.

[0167] Furthermore, when the top surface button 3 is not pressed, the protrusion 164 of the spacer 44 comes into contact with the upper protrusion 183 of the top surface key rubber 45. Therefore, the top surface key top 43 and the spacer 44 do not move unless a force is applied in the vertical direction. Furthermore, as described above, the top surface key rubber 45 deforms immediately in response to the start of pressing the top surface key top 43, making it easier to detect pressing of the top surface button 3. Note that in other embodiments, the protrusion of the spacer does not have to come into contact with the upper protrusion of the top surface key rubber in the above state.

[0168] Furthermore, when the top surface button 3 is not pressed, the lower protrusion 184 of the top surface key rubber 45 does not press the top surface input detection unit 41. At this time, the lower protrusion 184 of the top surface key rubber 45 may or may not be in contact with the top surface input detection unit 41 to the extent that almost no force is applied to the top surface input detection unit 41.

[0169] When the top surface keytop 43 is pressed by the user, the top surface keytop 43 and the spacer 44 move downward. When the top surface button 3 is pressed, the protrusion 164 of the spacer 44 comes into contact with the upper protrusion 183 of the top surface key rubber 45. Therefore, as the spacer 44 moves downward, the top surface key rubber 45 deforms, and the lower protrusion 184 of the top surface key rubber 45 moves downward. In the above state, the lower protrusion 184 of the top surface key rubber 45 comes into contact with the top surface input detection unit 41, so the lower protrusion 184 of the top surface key rubber 45 presses the top surface input detection unit 41. The top surface input detection unit 41 detects that the top surface button 3 has been pressed by detecting the lower protrusion 184 of the top surface key rubber 45. At this time, the top surface input detection unit 41 outputs a signal indicating that the button has been pressed.

[0170] As described above, in this embodiment, the electronic device 1 includes an optically transparent, elastically deformable rubber portion (i.e., top surface key rubber 45) between the spacer 44 and the substrate (i.e., upper substrate 40). When the keytop (i.e., top surface keytop 43) is pressed, the spacer 44 moves downward, and the protrusion 164 of the spacer 44 presses the detection portion (i.e., top surface input detection portion 41) via the rubber portion. This allows the rubber portion to apply a force that pushes the keytop back when pressed. Furthermore, because the detection portion is pressed via the rubber portion, it is possible to reduce unevenness in the pressing force when pressing the keytop.

[0171] In this embodiment, the detection unit (i.e., top surface input detection unit 41) is provided directly below the center position of the keytop (i.e., top surface keytop 43) (see FIG. 12). Therefore, the detection unit can more reliably detect pressing of the keytop.

[0172] In addition, in the present embodiment, the top surface input detection unit 41 has a function of generating a click feeling when pressed. For example, the top surface input detection unit 41 is a tactile switch. Note that the specific configuration for generating a click feeling when pressed is arbitrary. Here, in the present embodiment, by disposing a spacer 44 between the top surface key top 43 and the top surface key rubber 45, the top surface key rubber 45 can be thinned. Therefore, even when the top surface input detection unit 41 is pressed via the top surface key rubber 45, the click feeling by the top surface input detection unit 41 can be transmitted to the top surface key top 43, and a click feeling can be given to the user who has pressed the top surface button 3.

[0173] In the present embodiment, a depression that depresses downward is formed at a position including the protrusion 154 of the outer edge portion 152 of the top surface key top 43 and the portion directly below the hole 44a of the outer edge portion 162 of the spacer 44 in the bottom portion 181 of the top surface key rubber 45 (see FIG. 12). Further, a hole is formed at the above position in the upper substrate 40 (see FIG. 12). Thereby, when the top surface button 3 is pressed, the possibility that the lower end of the protrusion 154 (that is, the portion where heat caulking is performed) contacts the upper substrate 40 can be reduced. Note that in the present embodiment, the depression in the top surface key rubber 45 and the hole in the upper substrate 40 are set to such a size that the protrusion of the top surface key top 43 does not contact when the top surface button 3 is pressed.

[0174] In the present embodiment, the top surface button 3 can be illuminated by the light from the top surface light emitting unit 42 passing through the top surface button 3 and being emitted to the outside of the housing 2. Note that in the present embodiment, a film that scatters light is provided on the exposed surface of the top surface key top 43. Thereby, when the top surface light emitting unit 42 emits light, the exposed surface of the top surface button 3 appears to be illuminated.

[0175] Here, in the present embodiment, the spacer 44 can make the light from the light source be emitted evenly from the exposure surface. FIG. 13 is a diagram showing an example of the difference in the light path between the case where the spacer 44 is provided and the case where it is not provided. Note that (a) shown in FIG. 13 shows the light path in a configuration where the spacer 44 is not provided below the top surface key top 43, and (b) shown in FIG. 13 shows the light path in a configuration where the spacer 44 is provided below the top surface key top 43 as in the present embodiment. In FIG. 13, for the purpose of making the drawing easy to view, the light path of the light emitted only from one light emitting part 42 for the top surface is shown.

[0176] As shown in FIG. 13(a), when the spacer 44 is not provided, the top surface key top 43 is provided with a shaft portion 191 for pressing the top surface key rubber 193 instead of the spacer 44 when the top surface button 3 is pressed. This shaft portion 191 extends downward from the lower surface of the central portion 192 of the top surface key top 43. Therefore, while a part of the light emitted from the light emitting part 42 for the top surface has its light path changed by passing through the shaft portion 191 before being emitted from the exposure surface of the top surface key top 43, another part is emitted from the exposure surface without passing through the shaft portion 191. As a result, for example, in the example shown in FIG. 13(a), the interval between the path b and the path c on the exposure surface becomes wide. Therefore, unevenness is likely to occur in the light emitted from the exposure surface, and it becomes difficult to illuminate the exposure surface evenly. Also, even if the shaft portion 191 is made of a light-transmissive material, when light passes through the shaft portion 191, the loss is greater than when it passes through the air. Therefore, in the path c, the amount of light emitted from the exposure surface is smaller than that in the path b that does not pass through the shaft portion 191 by the amount of light passing through the shaft portion 191. For this reason too, unevenness is likely to occur in the light emitted from the exposure surface.

[0177] In contrast, when the spacer 44 is provided as shown in Fig. 13(b), the above-mentioned shaft portion 191 is not provided, and therefore the path of part of the light emitted from the top surface light-emitting portion 42 is not changed by the shaft portion 191. Therefore, for example, in the example shown in Fig. 13(b), the distance between path b and path c on the exposed surface is narrower than in the example shown in Fig. 13(a). Therefore, it is possible to make it less likely that unevenness will occur in the light emitted from the exposed surface, making it easier to make the exposed surface shine evenly.

[0178] In this embodiment, the protrusion 164 is provided on the lower surface of the spacer 44, but in other embodiments, the lower surface of the spacer may be flat (i.e., the protrusion 164 may not be provided). In this way, the path of the light emitted from the top surface light-emitting unit 42 will not be changed by passing through the protrusion 164, and therefore unevenness in the light emitted from the exposed surface will be less likely to occur.

[0179] In this embodiment, the protrusion 164 is provided at a position lower than the upper surface of the outer edge 152 of the top surface keytop 43 in the vertical direction (see FIG. 12). This makes it more difficult for light that passes from the top surface light-emitting unit 42, passes through the spacer 44, and is emitted from the exposed surface to pass through the protrusion 164, making it less likely for unevenness to occur in the light emitted from the exposed surface. The protrusion 164 may also be provided at a position lower than the lower surface of the outer edge 152 of the top surface keytop 43 in the vertical direction. This makes it more difficult for light that passes from the top surface light-emitting unit 42, passes through the spacer 44, and is emitted from the exposed surface to pass through the protrusion 164, making it more unlikely for unevenness to occur in the light emitted from the exposed surface.

[0180] In another embodiment, in order to reduce the unevenness in the light emitted from the exposed surface due to the above-mentioned shaft portion 191, instead of the configuration using a spacer, a configuration may be adopted in which the thickness (i.e., the length in the vertical direction) of the central portion of the top surface key top is increased, or a configuration may be adopted in which the thickness of the bottom portion of the top surface key lever is increased. The configuration of increasing the thickness of the central portion of the top surface key top means that, for example, the lower surface of the central portion of the top surface key top is set to the same height as the lower surface of the outer edge portion (i.e., the positions in the vertical direction are made the same), so that the lower surface of the central portion of the top surface key top contacts or is close to the top surface key lever 45.

[0181] Also, the configuration of increasing the thickness of the bottom portion of the top surface key lever means that, for example, the upper surface of the top surface key lever is arranged at a height such that it contacts or is close to the lower surface of the central portion of the top surface key top. An example of this configuration is shown in FIG. 14. FIG. 14 is a diagram showing an example of a comparative example of the top surface button 3. The comparative example shown in FIG. 14 differs from this embodiment in that no spacer is used and the shape of the top surface key lever is different.

[0182] In the above comparative example, the top surface key lever 200 has a central portion 201, a lower protruding portion 202, a skirt portion 203, a bottom portion 204, and a side wall portion 205. In the above comparative example, the central portion 201 is provided below the central portion 151 of the top surface key top 43. Also, the lower protruding portion 202 is provided at a position directly above the top surface input detection portion 41 on the lower surface of the central portion 201 and protrudes downward from the lower surface. Note that the central portion 201 of the top surface key lever 200 is formed thick so that its upper surface contacts the lower surface of the top surface key top 43 and the lower surface of the central portion 201 does not contact the top surface light emitting portion 42 when the top surface button 3 is pressed.

[0183] Further, the skirt portion 203 is provided so as to extend obliquely downward (more specifically, in a direction having a downward component and directed outward from the central portion 201) from the outer periphery of the lower surface of the central portion 201. The skirt portion 203 has the shape of a portion between two planes parallel to the horizontal direction passing through the side surface of a cone. The bottom portion 204 is provided so as to extend further outward in the horizontal direction from the outer periphery of the skirt portion 203. The side wall portion 205 has the same shape as the side wall portion 182 in the above-described embodiment and is provided so as to extend upward from the outer periphery of the bottom portion 204. The skirt portion 203, the bottom portion 204, and the side wall portion 205 each have an annular shape.

[0184] In the above comparative example, when the top surface key top 43 is pressed by a user, the top surface key top 43 moves downward. Accordingly, the central portion 201 of the top surface key lever 200 moves downward, and the downward protruding portion 202 presses the top surface input detection portion 41. The top surface input detection portion 41 detects that the top surface button 3 has been pressed by detecting that it has been pressed by the downward protruding portion 184 of the top surface key lever 45. Note that since the skirt portion 203 is deformed when the top surface key top 43 is pressed, when the pressing is released, the skirt portion 203 returns to its original shape, and the top surface key top 43 returns to the position before pressing.

[0185] In addition, in the case of a configuration in which the thickness of the central portion of the top surface key top 43 is increased, it may be difficult to manufacture the top surface key top 43 (for example, forming the film that scatters light as described above on the exposed surface). Also, in the case of a configuration in which the thickness of the bottom portion of the top surface key lever 45 is increased as in the above comparative example, the operating feeling when the top surface button 3 is pressed deteriorates (for example, since the top surface key lever 200 is thick, it takes a certain amount of deformation of the top surface key lever 200 before the pressing is detected, so the pressing is not detected immediately after the top surface key top 43 is pressed). On the other hand, in the present embodiment, by providing the spacer 44, it is not necessary to thicken the top surface key top 43 or the top surface key lever 45, so that the manufacture of the top surface key top 43 can be facilitated and the operating feeling when the top surface button 3 is pressed can be improved.

[0186] In other embodiments, the top surface key lever may have a structure with a skirt portion as shown in the above comparative example around the portion located directly above the top surface input detection unit 41 (i.e., the central portion 201), instead of the structure of the top surface key lever 45 in this embodiment. According to this, when the top surface button 3 is pressed, a click feeling can be generated by the top surface key lever. At this time, the top surface input detection unit 41 does not necessarily have a function of generating a click feeling. Note that, in order to generate a click feeling by the skirt portion of the top surface key lever, the skirt portion needs to have a certain height. On the other hand, in this embodiment, by not providing a skirt portion on the top surface key lever, the thickness of the top surface key lever can be reduced, and the thickness of the top surface button can be reduced.

[0187] (Assembly of the electronic device 1) In this embodiment, the electronic device 1 can be assembled, for example, by attaching each component to the upper housing 11 and attaching each component to the lower housing 12, and then fixing the upper housing 11 and the lower housing 12 to which each component is attached to each other. Regarding the upper housing 11, with the top surface button 3 arranged on the upper housing 11, the upper substrate 40 is attached to the upper housing 11, so that each component can be in an attached state. Regarding the lower housing 12, after attaching the side surface button 4, the bottom surface button 6, the vibrator 29, the pedestal 31 to which the speaker 30 is fixed, the lower substrate 32, the terminal 5 and the terminal substrate 26 to the lower housing 12, the holder 28 to which the rechargeable battery 27 is fixed is attached to the lower housing 12, so that each component can be in an attached state.

[0188] In this embodiment, the upper housing 11 and the lower housing 12 are fixed by a locking portion 211 and a locked portion 212. Specifically, the upper housing 11 has the locking portion 211 on the inner side of the housing 2 at the outer peripheral portion of the upper housing 11 (see FIG. 11). The locking portion 211 is provided so as to protrude downward from the lower end of the portion of the upper housing 11 excluding the locking portion 211. The locking portion 211 has a shaft portion extending downward from the above-mentioned portion of the upper housing 11 and a claw portion protruding outward (that is, to the outside of the upper housing 11) from the shaft portion. In FIG. 11, only two locking portions 211 are shown, but in this embodiment, the upper housing 11 has three locking portions. Also, in other embodiments, the number of locking portions is arbitrary. Further, the shapes of the locking portion and the locked portion are also arbitrary.

[0189] Also, the lower housing 12 has the locked portion 212 inside the lower housing 12 (see FIG. 9). The locked portion 212 has a shape that can be hooked by the locking portion 211, and is provided at a position where it is locked to the locking portion 211 in a state where the edge portion of the upper housing 11 and the edge portion of the lower housing 12 are aligned. In this embodiment, the locked portion 212 has a shape having a downward-facing surface extending toward the center of the housing 2. The claw portion of the locking portion 211 catches on the downward-facing surface, whereby the locking portion 211 is locked to the locked portion 212.

[0190] As described above, in this embodiment, the upper housing 11 has a locking portion 211, and the lower housing 12 has a locked portion 212 to which the locking portion 211 can be locked. Therefore, by locking the locked portion 212 with the locking portion 211, the upper housing 11 and the lower housing 12 can be fixed to each other. Furthermore, for example, if the upper housing 11 and the lower housing 12 are fixed by adhesive, each housing needs to have an adhesive surface, which may result in an increase in size of the housing. In contrast, in this embodiment, there is no need to provide an adhesive surface on each housing, which allows for a reduction in size of the housing. Note that in other embodiments, the lower housing may have a locking portion and the upper housing may have a locked portion. In other words, one of the upper housing and the lower housing may have a locking portion, and the other of the upper housing and the lower housing may have a locked portion.

[0191] In the lower housing 12, at least one (here, two) of the latched portions 212 is provided on a portion of the inner wall of the housing 2 that faces a surface parallel to the short axis of the rechargeable battery 27 (which can also be said to be a surface including the short side of the rechargeable battery 27) (see FIG. 9). Here, the space sandwiched between the surface parallel to the short axis of the rechargeable battery 27 and the inner wall of the housing is narrower than the space sandwiched between the surface parallel to the long axis of the rechargeable battery 27 and the side portion, making it difficult to place the vibrator 29 or speaker 30 in this space. By arranging a latched portion that is smaller than the vibrator 29 or speaker 30 in this space, it is possible to efficiently use the space inside the housing 2 to arrange components, and it is possible to reduce the size of the electronic device 1.

[0192] In this embodiment, the upper housing 11 and the lower housing 12 are also fixed to each other with screws. Specifically, holes 2d are formed on both the left and right sides of the terminals 5 in the side surface of the lower housing 12 (see FIG. 1). Although not shown, the upper housing also has screw holes formed at the back of the holes. The upper housing 11 and the lower housing 12 are fixed together by threading a screw into the screw hole of the upper housing 11 while passing through the hole in the lower housing 12. By fixing the upper housing 11 and the lower housing 12 in this way using screws in addition to the locking portion and the locked portion, the upper housing 11 and the lower housing 12 can be fixed together more firmly.

[0193] Furthermore, in this embodiment, when attaching the lower housing 12 to the upper housing 11, the top surface of the holder 28 and the bottom surface of the upper substrate 40 are bonded together. This allows the components inside the housing 2 to be more firmly fixed. As described above, in this embodiment, the upper substrate 40 is fixed to the upper housing 11, and the holder 28 is fixed to the lower housing 12. Therefore, the upper housing 11 and the lower housing 12 are fixed together not only by the engagement between the locking portions and the locked portions, but also by the adhesion between the holder 28 and the upper substrate 40. This allows the upper housing 11 and the lower housing 12 to be fixed together more firmly.

[0194] In this embodiment, the top surface of the housing 2 has a shape that bulges upward, and the bottom surface has a shape that bulges downward. Here, when viewed in a direction perpendicular to the up-down direction, the height of the lower housing 12 is higher than the height of the upper housing 11 (see FIG. 6 ). In other words, the boundary between the upper housing 11 and the lower housing 12 is located at a position different from the ends of the housings in the direction perpendicular to the up-down direction (e.g., the front end, rear end, right end, and left end) (specifically, it is located higher than the ends). This reduces the possibility that the boundary portion will collide with another object and cause the upper and lower housings to become detached. Furthermore, when a hole is formed in the side portion of the housing 2 as in this embodiment, the heights of the two housings 2 can be made different, so that the hole can be formed in one of the housings 2 (here, the lower housing 12). This allows the opening of the hole to be formed as an integrated part, thereby improving the strength of the hole portion.

[0195] [3. Electrical configuration] 15 is a block diagram showing the electrical connection relationships of the components included in electronic device 1. As shown in Fig. 15, control circuit 221 is electrically connected to rechargeable battery 27, acceleration sensor 222, terminal 5, bottom input detection unit 223, side input detection unit 25, top input detection unit 41, side light-emitting unit 224, top light-emitting unit 42, and antenna 225.

[0196] The control circuit 221 is a processing circuit including a processor and a memory, and is, for example, an MCU (Micro Controller Unit). The control circuit 221 is electrically connected to the rechargeable battery 27 via the connector 141 provided on the lower substrate 32. The control circuit 221 supplies power from the rechargeable battery 27 to each component electrically connected to the control circuit 221 (specifically, the acceleration sensor 222, the bottom input detection unit 223, the side input detection unit 25, the top input detection unit 41, the side light-emitting unit 224, the top light-emitting unit 42, and the antenna 225). Furthermore, when the terminal 5 is electrically connected to, for example, a charger or an AC adapter, and external power is supplied to the electronic device 1 from the terminal 5, the control circuit 221 charges the rechargeable battery 27 with the supplied power.

[0197] Furthermore, the control circuit 221 acquires a signal output from the acceleration sensor 222. This signal indicates, for example, the detection result detected by the acceleration sensor 222 (i.e., the acceleration applied to the electronic device 1). For example, the control circuit 221 executes processing based on the detection result, or transmits the detection result to the information processing device via the antenna 225. Based on the detection result by the acceleration sensor 222, the control circuit 221 may calculate, for example, exercise information related to the exercise performed by the user (for example, information indicating that the user is walking or information indicating the number of steps taken by the user), or body movement information related to the body movement of the user while sleeping (for example, information indicating that the user has turned over in bed while sleeping).

[0198] The control circuit 221 also acquires signals from each input detection unit (specifically, the bottom input detection unit 223, the side input detection unit 25, and the top input detection unit 41). These signals indicate, for example, the detection results of the input detection units, i.e., whether or not there is an input to each button (specifically, the bottom button 6, the side button 4, and the top button 3). The control circuit 221, for example, executes processing based on the detection results, or transmits the detection results to the information processing device via the antenna 225.

[0199] Further, the control circuit 221 causes each light emitting unit (specifically, the side surface light emitting unit 224 and the top surface light emitting unit 42) to emit light by supplying power thereto. The control circuit 221 causes each light emitting unit to emit light, for example, according to the result of the processing executed by the control circuit 221 or an instruction from an information processing apparatus received via the antenna 225.

[0200] [4. Effects and Modifications of the Present Embodiment] (Configuration Regarding Diagonal Arrangement of Rechargeable Battery 27) As described above, in the above embodiment, the electronic device 1 includes the following configuration. · A housing 2 having a top surface and a bottom surface, being flat with a length in the vertical direction shorter than the length in the direction perpendicular to the vertical direction, and having a circular cross-sectional shape in a reference plane perpendicular to the vertical direction · Charging terminals (i.e., terminals 5) exposed on the side surface portion between the top surface and the bottom surface of the housing 2 · A rectangular parallelepiped rechargeable battery having a cross-sectional shape in the reference plane that is rectangular with a first long side and a first short side, and from a first position (i.e., the front end position of the housing 2) where the charging terminal is exposed on the side surface portion to a second position on the side surface portion that is on the opposite side of the first position (more specifically, the position on the opposite side of the first position with respect to the center of the housing 2 when viewed from above) (i.e., the rear end position of the housing 2), the rechargeable battery 27 provided inside the housing 2 is arranged such that the first long side is diagonal in the reference plane. · At least one of a vibrator 29 and a speaker 30 provided at a position intersecting the reference plane and at a position between the first long side of the rechargeable battery 27 and the portion of the side surface portion facing the first long side in the reference plane.

[0201] As described above, in the above embodiment, the rechargeable battery is disposed at an angle, which makes it easier to arrange the rechargeable battery and the charging terminal without interfering with each other. Furthermore, by disposing the vibrator and / or speaker between the diagonally disposed rechargeable battery and the housing, the rechargeable battery, the charging terminal, and the vibrator and / or speaker can be arranged at positions where they intersect with the reference plane. This allows for the miniaturization of the electronic device, or allows larger components (e.g., the rechargeable battery, vibrator, speaker, etc.) to be arranged within the housing. In this way, the above embodiment allows for an improved arrangement of components within the electronic device.

[0202] In the above embodiment, the electronic device 1 includes both the vibrator 29 and the speaker 30, but in other embodiments, the electronic device may include only one of the vibrator 29 and the speaker 30. Even in this case, similar to the above embodiment, the rechargeable battery 27 can be disposed at an angle to improve the layout of the components inside the electronic device 1.

[0203] In the above embodiment, the housing 2 has a top surface that bulges upward and a bottom surface that bulges downward. The housing 2 may have at least one of a top surface that bulges upward and a bottom surface that bulges downward. When the housing 2 has such a shape, the vertical length of the outer periphery of the housing 2 when viewed from above is shorter than the length of the center, and therefore the space available for arranging components near the periphery inside the housing 2 is limited. In this regard, in the present embodiment, by arranging the rechargeable battery 27 at an angle as described above, components such as the charging terminal 5, the vibrator 29, and / or the speaker 30 can be more easily arranged even when the arrangement space is limited.

[0204] Further, in the above embodiment, the electronic device 1 further includes a first input unit (i.e., the side button 4) provided at the second position where operation input by the user is performed. In the above embodiment, by arranging the rechargeable battery 27 obliquely as described above, the first input unit can be arranged on the side surface portion of the housing 2 without interfering with the rechargeable battery 27.

[0205] Also, in the above embodiment, the electronic device 1 further includes a second input unit (i.e., the top surface button 3) provided on the top surface of the housing 2 and a first substrate (i.e., the upper substrate 40). The first substrate is provided on the top surface side of the rechargeable battery 27 inside the housing 2, and an input detection unit for converting an input made to the second input unit into a signal is provided on the first substrate. According to this, by collectively arranging each component for detecting an input to the second input unit above the rechargeable battery 27, each of these components can be arranged by efficiently using the space inside the housing.

[0206] Furthermore, in the above embodiment, the electronic device 1 further includes a second substrate (i.e., the lower substrate 32) provided on the bottom surface side of the rechargeable battery 27 inside the housing 2. According to this, by dividing the substrate into two, the size of one substrate can be reduced, so that the electronic device 1 can be miniaturized.

[0207] Also, in the above embodiment, it can also be said that the electronic device 1 has the following configuration. · A housing 2 having a top surface and a bottom surface, with the length in the vertical direction being shorter than the length in the direction perpendicular to the vertical direction and being circular when viewed from above · A rectangular parallelepiped-shaped rechargeable battery 27 provided inside the housing 2 and having a first long side and a first short side when viewed from above · A terminal 5 provided between the first long side when viewed from above and the portion of the outer periphery of the housing 2 facing the first long side, with a part being exposed · When viewed from above, at least one of the vibrator 29 and the speaker 30 provided between the first long side and the portion of the inner circumference of the housing 2 facing the first long side, or between the second long side which is the opposite side of the first long side and the portion of the inner circumference of the housing 2 facing the second long side

[0208] In the present specification, "a certain component (specifically, the terminal 5, the vibrator 29, or the speaker 30) is provided between the long side of the rechargeable battery and the portion of the housing facing the long side" means that a part of the certain component exists in the space between the long side of the rechargeable battery and the portion of the housing facing the long side, and it does not mean that all of the certain component exists in the space.

[0209] As described above, in the above embodiment, by arranging the rechargeable battery 27 obliquely, it becomes easier to arrange the rechargeable battery 27 and the terminal 5 without interference. Further, by arranging the vibrator 29 and / or the speaker 30 between the obliquely arranged rechargeable battery 27 and the housing 2, it becomes easier to arrange the rechargeable battery 27 and the vibrator 29 and / or the speaker 30 without interference. Thus, according to the above embodiment, the arrangement of the components inside the electronic device 1 can be improved.

[0210] (Configuration regarding the arrangement of the substrate and the rechargeable battery 27, etc.) As described above, in the above embodiment, the electronic device 1 includes the following configuration. · A housing 2 having a top surface and a bottom surface, and being flat with a length in the vertical direction shorter than the length in the direction perpendicular to the vertical direction · A flat rechargeable battery 27 provided at a position intersecting with a reference plane perpendicular to the vertical direction inside the housing 2 · A first substrate (i.e., the upper substrate 40) provided parallel to the reference plane on the top surface side of the rechargeable battery 27 · A second substrate (i.e., the lower substrate 32) provided parallel to the reference plane on the bottom surface side of the rechargeable battery 27 · At least one of the vibrator 29 and the speaker 30 provided at a position intersecting with the reference plane

[0211] In the above embodiment, it can also be said that the electronic device 1 has the following configuration. A housing 2 having a top surface and a bottom surface, the length in the vertical direction being shorter than the length in the direction perpendicular to the vertical direction. A flat rechargeable battery 27 is provided inside the housing 2 in a direction perpendicular to the up-down direction. A first substrate (i.e., upper substrate 40) that is provided parallel to the top surface and closer to the top surface than the rechargeable battery 27. A second substrate (i.e., lower substrate 32) that is provided parallel to the bottom surface and closer to the bottom surface than the rechargeable battery 27. At least one of a vibrator 29 and a speaker 30 provided between the side surface of the rechargeable battery 27 and the inner periphery of the housing 2

[0212] According to the above configuration, by disposing the two boards separately on either side of the rechargeable battery 27, the boards can be efficiently arranged inside the housing 2, thereby achieving a reduction in the size of the electronic device 1. Furthermore, by disposing the vibrator 29 and / or the speaker 30 on the sides of the rechargeable battery 27, the electronic device 1 can be made thinner. In this way, according to the above embodiment, the arrangement of the components inside the electronic device 1 can be improved.

[0213] As described above, in this embodiment, the reference plane is a plane perpendicular to the up-down direction that maximizes the cross-sectional area of the space inside the housing 2. By arranging the rechargeable battery 27 and at least one of the vibrator 29 and the speaker 30 so that they intersect with this reference plane, the electronic device 1 can be made smaller.

[0214] Also, as described above, in the above embodiment, the top surface and the bottom surface of the housing 2 have a shape that bulges in the vertical direction, and the space for arranging components is restricted in the vicinity of the outer periphery inside the housing 2. Regarding this, in the present embodiment, by arranging the rechargeable battery 27, each substrate, and the vibrator 29 and / or the speaker 30 as described above, even in a state where the arrangement space is restricted, it becomes easier to arrange components such as the rechargeable battery 27, the vibrator 29, and / or the speaker 30.

[0215] (Configuration regarding the top surface button 3) In the above embodiment, the electronic device 1 includes a button device (that is, the top surface button 3, the top surface input detection unit 41, the top surface light emitting unit 42, and the upper substrate 40) having the following configuration. · A key top having light transmissibility (that is, the top surface key top 43) · A spacer 44 provided below the key top and having light transmissibility · A substrate provided below the spacer 44 and having a light emitting unit (that is, the top surface light emitting unit 42) and a detection unit (that is, the top surface input detection unit 41) on the upper surface Here, the lower surface at the central portion of the key top is located above the lower surface at the outer edge portion around the central portion (see FIG. 12). The spacer 44 has a protruding portion that protrudes downward from the flat portion of the lower surface above the detection unit on the lower surface at the central portion of the spacer 44, and the flat portion is located above the lower surface at the outer edge portion around the central portion (see FIG. 12). In response to the downward movement of the spacer 44 due to the pressing of the key top, the protruding portion presses the detection unit.

[0216] Note that "a certain component is located above another component" means that the vertical position of a certain component is above the vertical position of another component, and it is not limited to the meaning that the two components are arranged so that a certain component and another component appear to overlap when viewed from above (that is, a certain component is located above another component).

[0217] According to the above configuration, by forming the spacer 44 into the above shape (that is, a shape in which the lower surface at the central portion is located above the lower surface at the outer edge portion), the possibility of other components (for example, the spacer 44) coming into contact with the components on the substrate (for example, the light-emitting portion) can be reduced. In addition, since the spacer 44 itself can be made thinner, the thickness of the button device can be reduced.

[0218] Note that the above button device can also be used in an electronic device different from the electronic device 1 in the present embodiment. For example, the above button device may be used in an electronic device having a spherical housing. At this time, the direction in which the pressed key top moves is downward, and the direction opposite to the downward direction is upward.

[0219] In the above embodiment, the electronic device 1 has a top surface provided with the key top of the button device and a bottom surface having a shape bulging downward (see FIG. 1). At this time, the electronic device 1 is likely to tilt obliquely. When the key top is pressed in a state where the electronic device 1 is placed on a plane such that the lower surface of the electronic device 1 is in contact, the user is likely to press the key top obliquely. Then, when the key top is pressed obliquely, there is a risk that other components will come into contact with the substrate. In this regard, in the above embodiment, by forming the spacer 44 into the above shape, even when the key top is pressed obliquely, the possibility of other components coming into contact with the substrate can be reduced.

[0220] (Modification Example Regarding Rechargeable Battery) Note that in other embodiments, the electronic device may be configured to include a housing case capable of accommodating a battery (in the sense including a rechargeable battery) instead of the rechargeable battery 27. That is, the electronic device may be configured to include a power supply unit (the power supply unit is a general term for the housing case and the battery), which is either the housing case or the battery.

[0221] The storage case removably houses the battery. The storage case is rectangular like the rechargeable battery 27. The storage case may also be flat, with its vertical length shorter than its length perpendicular to the vertical direction. When the electronic device includes a storage case instead of the rechargeable battery 27, the electronic device may or may not include the holder 28. When the electronic device does not include the holder 28, the storage case may have an arm similar to the first arm 123 of the holder 28 (i.e., an arm that extends above the vibrator 29 and presses down on the vibrator 29 from above). In the above case, the storage case may also have an arm similar to the second arm 124 of the holder 28 (i.e., an arm that extends above the speaker 30 and presses down on the speaker 30 from above).

[0222] Furthermore, if the electronic device has a housing case instead of the rechargeable battery 27, the electronic device does not need to have a charging terminal. In this case, the electronic device may have the same terminal 5 as in the above embodiment, and the terminal 5 may be used for communication with other devices.

[0223] The storage case may also have a shape in which one of its four sides is open (i.e., one side is missing, or one side has a hole). In this case, a hole is formed in the housing at a portion facing the open side of the storage case, and the electronic device is provided with a battery cover attached to cover the hole. The hole is large enough to allow a battery to be inserted into the storage case from outside the housing through the hole. The battery cover is also detachable from the housing. With the above configuration, the user can easily replace the battery in the storage case.

[0224] More specifically, the open side may be a side parallel to the minor axis of the case, which allows the vibrator and speaker, located on the side parallel to the major axis of the case, to be out of the way when removing or inserting the battery from the case, making it easier to replace the battery inside the case.

[0225] In another embodiment, the storage case may have a shape with an open bottom, similar to the holder 28 in the above embodiment. At this time, a hole is formed in the portion of the bottom surface of the housing that faces the opening of the storage case, and the electronic device includes a battery cover attached so as to cover the hole. The lower substrate is disposed above the storage case (and below the upper substrate). The bottom button is provided in a portion of the bottom surface of the housing other than the above hole (alternatively, a button having the same function as the bottom button may be provided on the side surface or the top surface of the housing). With the above configuration, the user can easily replace the battery in the storage case.

[0226] In the above embodiment, the rechargeable battery 27, which is an example of the power supply unit, has a rectangular shape when viewed from above, but the shape of the power supply unit is not limited to this. For example, in another embodiment, the power supply unit may have a square shape when viewed from above. At this time, the power supply unit does not have to be arranged such that the sides parallel to the horizontal plane are inclined with respect to the front-rear direction. Regardless of the shape of the power supply unit, by arranging the two substrates on the upper and lower sides of the power supply unit, the substrates can be efficiently arranged inside the housing.

[0227] (Modification of the shape of the housing) In the above embodiment, the housing has a flat shape when viewed from the horizontal direction and a circular shape when viewed from above, but the shape of the housing is not limited to this. The shape of the housing (which can also be referred to as the external shape of the electronic device) may be, for example, the following shapes.

[0228] In another embodiment, the housing may have a shape formed by a curve that bulges outward when viewed from above and has a longitudinal direction (for example, an elliptical shape or an oval shape). Even if the housing has such a shape, by arranging the long axis of the power supply unit obliquely with respect to the front-rear direction as in the above embodiment, it becomes easier to arrange the power supply unit without buffering against other components (for example, terminals and / or side buttons).

[0229] In addition, when the longitudinal direction of the housing coincides with the front-rear direction (that is, when a side button is provided at one end in the longitudinal direction and a terminal is provided at the other end in the longitudinal direction), the power supply unit may be arranged such that the major axis of the power supply unit is inclined with respect to the front-rear direction and the major axis is closer to the longitudinal direction than the short-side direction of the housing (for example, the angle formed by the major axis and the longitudinal direction is less than 45°). According to this, it becomes easier to arrange a larger power supply unit.

[0230] Also, the housing may be rectangular when viewed from above. Regardless of the shape of the housing when viewed from above, by arranging the two substrates separately on the upper and lower sides of the power supply unit, the substrates can be efficiently arranged inside the housing.

[0231] In other embodiments, the housing may not be flat and may have a shape (for example, spherical) in which the length in the vertical direction is the same as the length in the direction perpendicular to the vertical direction. When the housing has such a shape, the vibrator may be arranged below the power supply unit. Note that the downward direction of the power supply unit in this case is the direction perpendicular to the widest surface among the surfaces of the rectangular parallelepiped-shaped power supply unit and is the direction from the power supply unit to the lower substrate. Also, in the above case, the speaker may be arranged so as to extend downward from a position on the side of the power supply unit. In the above case, since a space for arranging components is likely to be generated below the power supply unit, by arranging the vibrator and the speaker as described above, it becomes easier to arrange a larger vibrator and speaker.

[0232] (Modification regarding the arrangement of the side button and the terminal) In the above embodiment, the side button 4 and the terminal 5 are located symmetrically with respect to the center of the housing 2 when viewed from above. However, the arrangement of the side button and the terminal is not limited to this. For example, the side button may be located at a position other than the rear end of the housing 2, and the terminal may be located at a position other than the front end of the housing 2. Furthermore, the electronic device may not have a side button or a terminal. If the electronic device does not have a terminal on the side of the housing, the front-to-rear direction of the electronic device may be determined based on the side button. For example, the direction perpendicular to the up-down direction, from the center of the housing to the side button, may be defined as the rear direction, and the direction opposite to the rear direction may be defined as the front direction. Even if the positions of the side button and the terminal are different from those in the above embodiment, the power supply unit may be located so as not to interfere with the side button and the terminal. For example, the power supply unit may be located so that the side button and the terminal are located in the space (e.g., space A and / or space B shown in FIG. 9 ) between the side of the power supply unit and the portion of the inner wall of the housing 2 (more specifically, the inner wall of the side portion of the housing 2) facing the side.

[0233] (Modifications regarding the input unit) In the above embodiment, each input unit (i.e., the top button 3, the side button 4, and the bottom button 6) through which the user performs an operation input is an input unit of a type that the user can press, but the type of input unit is not limited to this. For example, in other embodiments, the input unit may be a slide switch or a touch button that detects a user's touch input with a touch sensor. The input unit may also be an input unit of a type that allows directional input (e.g., a joystick). Furthermore, the input unit may be an input unit of a type that the user can press and that allows directional input (e.g., a joystick that allows press input). For example, the electronic device may be configured such that a joystick is provided on the top surface instead of the top button.

[0234] In other embodiments, the sizes, shapes, numbers, installation positions, and installation methods of the components provided on the surface and inside of the housing are arbitrary. The electronic device may not include some of the components in the above embodiments, or may not execute some of the processes executed in the above embodiments. For example, in order for the electronic device to exhibit some specific effects in the above embodiments, it may include the components for achieving the effects and execute the processes for achieving the effects, and may not include other components or execute other processes. Also, in other embodiments, the electronic device may include components different from those in the above embodiments.
