In this case, the second panel 32 faces the front surface of the electronic device 1. The display unit 20 is joined to the second panel side of the first panel 31. That is, the display unit 20 is joined to the inside of the housing 10. It can be said that the display unit 20 is joined to the housing 10 via the composite panel 30.

  When the second panel 32 faces the front surface of the electronic device 1, the first panel 31 is less likely to be damaged even when the electronic device 1 receives an impact. As a result, the first panel 31 is hardly cracked.

  As shown in FIG. 4, the housing 10 includes a rib 11, a back surface portion 14, and a support portion 12. The rib 11 is provided so as to surround the first surface of the housing 10. The back surface part 14 is provided on the surface opposite to the first surface. The support portion 12 is provided at the end of the composite panel 30 in the negative direction of the Y axis. The composite panel 30 is supported by the rib 11 and the support portion 12. The composite panel 30 may be bonded to the rib 11 and the support portion 12 with an adhesive or the like.

  The electronic device 1 includes a speaker 50, a microphone 52, and an atmospheric pressure sensor 54 in a portion covered with the front panel 40. The speaker 50 has a predetermined waterproof performance. The microphone 52 and the atmospheric pressure sensor 54 are covered with a waterproof sheet 56 having a predetermined waterproof performance. The waterproof sheet 56 allows air to pass through. By allowing the waterproof sheet 56 to pass air, the volume of sound passing through the waterproof sheet 56 is not easily attenuated, and the accuracy of the atmospheric pressure measured by the atmospheric pressure sensor 54 via the waterproof sheet 56 can be improved.

  In this embodiment, predetermined waterproof performance shall be prescribed | regulated by the magnitude | size of the water pressure which can be used even if the electronic device 1 is submerged. The predetermined waterproof performance may be defined by a usable time even when the electronic device 1 is submerged. The front panel 40 protects the speaker 50, the microphone 52, and the atmospheric pressure sensor 54. The cover portion 43 protects the speaker 50, the microphone 52, and the atmospheric pressure sensor 54 while allowing air to pass between the outside and the inside of the housing 10. Since the cover part 43 protects the inside of the housing 10, the impact resistance of the electronic device 1 can be improved. The cover part 43 makes it difficult for a human body or an object to come into direct contact with the waterproof sheet 56. As a result, the waterproof performance of the waterproof sheet 56 is easily maintained.

  As shown in FIG. 5, the housing 10 includes a rib 11, a back surface portion 14 provided on the negative direction side of the Z axis, and a support portion 12. The electronic device 1 includes an internal structure 60 in a region surrounded by the rib 11, the back surface portion 14, and the composite panel 30.

  The internal structure 60 may be, for example, a battery or a substrate including a processor or an electronic circuit that functions as a control unit that controls each component of the electronic device 1. The housing 10 has a predetermined waterproof performance so that water does not enter the region where the internal structure 60 is located. Since the housing 10 has a predetermined waterproof performance, the risk of failure due to water adhering to the battery or the substrate can be reduced.

  The control unit of the electronic device 1 is configured as a processor, for example. The control unit may include one or more processors. The processor may include a general-purpose processor that reads a specific program and executes a specific function, and a dedicated processor specialized for a specific process. The dedicated processor may include an application specific integrated circuit (IC). The application specific IC is also called ASIC (Application Specific Integrated Circuit). The processor may include a programmable logic device. The programmable logic device is also called a PLD (Programmable Logic Device). The PLD may include an FPGA (Field-Programmable Gate Array). The control unit may be any of SoC (System-on-a-Chip) and SiP (System In a Package) in which one or a plurality of processors cooperate.

  When the internal structure 60 is located on the negative side of the Z axis when viewed from the front panel 40, the inclined part 42 is positioned on the negative side of the Z axis from the convex part 41, so that the inclined part 42 is external. The frequency with which impacts are applied to the internal structure 60 can be reduced.

  The display unit 20 displays characters, images, operation objects, pointers, and the like based on information acquired from the control unit or the like of the electronic device 1. The display unit 20 may be a display device such as a liquid crystal display, an organic EL (Electroluminescence) display, or an inorganic EL display, but is not limited thereto.

  The first panel 31 may include a touch sensor. The 1st panel 31 provided with a touch sensor is also called a touch panel. The touch panel can detect a touch by a user as an input. The touch panel to which the display unit 20 is bonded is also referred to as a touch panel display.

  As shown in FIG. 5, the electronic device 1 includes a speaker 50, a microphone 52, an atmospheric pressure sensor 54, and a waterproof sheet 56 in an area covered with the front panel 40. The front panel 40 can mitigate the impact on the speaker 50, the microphone 52, the atmospheric pressure sensor 54, and the waterproof sheet 56. The waterproof sheet 56 covers the microphone 52 and the atmospheric pressure sensor 54. A gap 58 may exist between the cover portion 43 of the front panel 40 and the speaker 50 or the waterproof sheet 56.

  In FIG. 5, the microphone 52 and the atmospheric pressure sensor 54 covered with the waterproof sheet 56 are located between the two speakers 50. The positional relationship among the speaker 50, the microphone 52, and the atmospheric pressure sensor 54 is not limited to the example in FIG. The speaker 50, the microphone 52, and the atmospheric pressure sensor 54 may be arranged in various ways.

  The speaker 50 emits sound based on information acquired from the control unit or the like of the electronic device 1. The speaker 50 may emit sound included in the content when the electronic device 1 reproduces content such as music or video. The speaker 50 may emit a ringing tone or the voice of the other party when performing electronic communication in the electronic device 1. The speaker 50 may output the other party's voice at a high volume when the electronic device 1 operates as a speakerphone. The speaker 50 is not limited to these examples, and may emit various sounds.

  The speaker 50 is acoustically connected to the outside of the housing 10 through the cover portion 43. That is, a sound transmission path is ensured through the cover 43 between the speaker 50 and the outside of the housing 10. Sound emitted from the speaker 50 is output to the outside of the housing 10 through the cover portion 43 of the front panel 40.

  The microphone 52 acquires input sound. The microphone 52 generates information based on the input sound and outputs it to the control unit of the electronic device 1. The microphone 52 may acquire sound when recording or recording in the electronic device 1. When the electronic device 1 performs voice communication in the electronic device 1, the microphone 52 may acquire voice to be transmitted to the other party. The microphone 52 is not limited to these examples, and may acquire various sounds.

  The microphone 52 is acoustically connected to the outside of the housing 10 through the cover portion 43 and the waterproof sheet 56. That is, a sound transmission path is secured between the microphone 52 and the outside of the housing 10 through the cover portion 43 and the waterproof sheet 56. Sound from the outside of the housing 10 is input to the microphone 52 through the cover portion 43 of the front panel 40 and the waterproof sheet 56.

  The atmospheric pressure sensor 54 measures the atmospheric pressure outside the housing 10 by being connected to the outside of the housing 10 through the cover portion 43 and the waterproof sheet 56. The atmospheric pressure sensor 54 outputs information related to the atmospheric pressure outside the housing 10 to the control unit or the like of the electronic device 1.

  4 and 5, the speaker 50 and the microphone 52 are disposed on the negative direction side of the Y axis of the housing 10. The speaker 50 and the microphone 52 may be further disposed on the positive side of the Y axis of the housing 10. When the electronic device 1 performs voice communication, the speaker 50 disposed on the positive direction side of the Y axis of the housing 10 may function as a receiver. When the electronic device 1 operates as a speakerphone, the microphone 52 arranged on the positive side of the Y axis of the housing 10 may acquire sound to be transmitted to the other party.

  As shown in FIG. 6, the front panel 40 is detachably disposed on the front surface side of the electronic device 1 so as to cover an end portion of the first panel 31 on the first surface side. By doing in this way, the impact to the edge part of the 1st panel 31 can be relieved. As a result, the first panel 31 is not easily damaged. The front panel 40 is positioned so that the end of the second panel 32 is exposed. By doing so, the front panel 40 is positioned side by side with the second panel 32 on the front surface of the electronic device 1. Compared with the case where the front panel 40 is positioned so as to overlap the second panel 32, the thickness of the electronic device 1 can be reduced.

  The electronic device 1 has a jig 33 (see FIG. 11) for peeling the second panel 32 at the interface where the first panel 31 and the second panel 32 are joined in a state where the front panel 40 is removed from the housing 10. ) Can be inserted. In other words, the electronic device 1 may be configured to be accessible to the interface where the first panel 31 and the second panel 32 are joined in a state where the front panel 40 is detached from the housing 10.

(Configuration of the second panel)
As shown in FIG. 7, the second panel 32 includes a surface portion 321 and a base material 322. The surface portion 321 is located on the front side of the electronic device 1 and is directly touched with a user's finger or the like. The surface portion 321 may be a material having a relatively high hardness. The surface portion 321 may be made of a material that is resistant to a touch such as a finger. The surface portion 321 may be made of a material that is not easily damaged by collision of an object or the like. The surface portion 321 may be made of a material that is difficult to penetrate the colliding object. The surface portion 321 may have a predetermined thickness. The predetermined thickness may be a thickness determined according to the material so that the colliding object is difficult to penetrate. The surface portion 321 may be, for example, an acrylic resin. The surface portion 321 is not limited to an acrylic resin, for example, and may be an organic resin.

  The second panel 32 includes a first adhesive material 323 between the surface portion 321 and the base material 322. The surface portion 321 and the base material 322 are joined by the first adhesive material 323. The first adhesive material 323 may be a material having a high bonding strength with respect to the surface portion 321. When the surface portion 321 is an acrylic resin, the first adhesive material 323 may be an acrylic adhesive material or the like. When the surface portion 321 is an organic resin, the first adhesive material 323 may be an organic adhesive material or the like.

  The second panel 32 has a second adhesive material 324 on the second surface side of the substrate 322. The second panel 32 is joined to the glass surface 311 of the first panel 31 by the second adhesive material 324. The glass surface 311 is a surface on the first surface side of the first panel 31. The second adhesive material 324 may be a material having a high bonding strength with respect to the glass surface 311. The second adhesive material 324 may be a silicon-based adhesive material or the like.

  The base material 322 may be a material having high bonding strength with respect to both the first adhesive material 323 and the second adhesive material 324. When the first adhesive material 323 and the second adhesive material 324 are an acrylic adhesive material and a silicon adhesive material, respectively, the base material 322 may be made of, for example, PET (Polyethylene Terephthalate).

  The surface portion 321 has an antifouling layer 325 on the first surface side corresponding to the front surface side of the electronic device 1. The antifouling layer 325 makes it difficult for oil and fat components such as fingerprints due to a user's touch to adhere. As a result, the composite panel 30 can be difficult to get dirty. The antifouling layer 325 may be a layer formed by various surface treatments such as fluorine coating.

  Since the composite panel 30 includes the second panel 32, the first panel 31 is less likely to be damaged as compared with a panel made of only glass. As a result, the panel can be difficult to break. The composite panel 30 can be hardly contaminated by having the antifouling layer 325 on the front side of the electronic device 1. Unlike the panel made of only glass, the composite panel 30 does not have a possibility that dirt will adhere to the glass surface 311 covered with the second panel 32. The glass surface 311 may not be provided with an antifouling coat such as a fluorine coat. By bonding the second panel 32 directly to the glass surface 311, the bonding strength between the first panel 31 and the second panel 32 can be increased.

  For example, in a device such as a smartphone provided with a panel made of only glass, an antifouling coat may be applied to the surface of the panel. A user may use a device by attaching a protective sheet to a panel provided with an antifouling coating. The antifouling coat is a process that makes it difficult for dust and the like to adhere. The adhesive strength of the protective sheet with respect to the panel to which the antifouling coat is applied can be lower than the adhesive strength to the panel without the antifouling coat.

  The adhesive strength can be measured as a force necessary for peeling two sheets adhered to each other at a constant speed. The first panel 31 and the protective sheet can be regarded as a rigid material and a flexible material, respectively. When measuring the adhesive strength between the rigid material and the flexible material, the sheet may be peeled off by 180 degree peeling. 180 degree peeling is a method in which a flexible material is bent at an angle close to 180 degrees and peeled from a rigid material. According to the actual measurement result, the adhesive strength between the first panel 31 coated with antifouling and the protective sheet is 10 of the adhesive strength between the first panel 31 not coated with antifouling and the protective sheet. It was less than 1 / min. That is, the antifouling coat reduces the adhesive strength of the protective sheet. The peeling method used for measuring the adhesive strength may be another form of peeling method such as T-type peeling.

  The protective sheet attached to the first panel 31 with the antifouling coating may be easily peeled off when the user's nails are caught on the edge of the protective sheet when the electronic apparatus 1 is normally used. is there. In addition, the protective sheet attached to the first panel 31 with the antifouling coating easily deteriorates in adhesive strength due to the entry of oil or moisture into the adhesive interface between the protective sheet and the first panel 31. May peel off. In addition, the protective sheet attached to the first panel 31 with the antifouling coating may be warped and deformed due to the influence of heat or humidity, and the adhesive strength may be easily peeled off without being able to withstand the deformation. On the other hand, the composite panel 30 according to the present embodiment joins the second panel 32 to the glass surface 311 of the first panel 31 that is not subjected to the antifouling coating. By doing in this way, the 2nd panel 32 becomes difficult to peel compared with the case where a user sticks a protection sheet.

  The second panel 32 makes the first panel 31 difficult to be damaged. Instead of scratching the first panel 31, the second panel 32 may be scratched. The composite panel 30 is configured to be peelable while being configured so that the first panel 31 and the second panel 32 are difficult to peel off. Since the second panel 32 is configured to be peelable, only the second panel 32 can be replaced when the second panel 32 is damaged. In this case, the first panel 31 may not be replaced. As a result, repair can be facilitated.

  The first panel 31 may have a curved shape in a region near the end of the housing 10. The second panel 32 joined to the first panel 31 having a curved shape may be easily peeled off at an end portion where the curvature of the curvature is increased. When the second panel 32 has a relatively low flexibility, it is more easily peeled off from the first panel 31 having a curved shape. When the first panel 31 is provided with an antifouling coating, the second panel 32 is more easily peeled off from the first panel 31. Even if the second panel 32 has a relatively low flexibility by being joined to the glass surface 311 of the first panel 31 to which the antifouling coating is not applied, the second panel 32 has a curved shape. It becomes difficult to peel from the 1st panel 31 which has.

  The texture received by the user when touching a panel made of resin alone may be different from the texture received when touching a panel containing glass. The composite panel 30 according to the present embodiment can provide the texture received from the panel containing glass and can reduce the risk of occurrence of cracks in the panel containing glass.

  When the second panel 32 is bonded to the glass surface 311, the second adhesive material 324 may be configured to prevent bubbles from remaining in the bonded portion. For example, the second adhesive material 324 can be configured such that bubbles are easily removed from the joint portion by appropriately setting the ratio of the slightly adhesive component and the strong adhesive component.

  The first panel 31 and the display unit 20 may be joined with a photo-curing material that is cured by irradiation with UV (Ultra Violet) light or the like. When the first panel 31 and the display unit 20 are bonded with a material that is cured by irradiation with UV light, the second panel 32 is bonded to the first panel 31 after the first panel 31 and the display unit 20 are bonded. May be joined. By doing so, the second panel 32 is not irradiated with UV light or the like. As a result, deterioration of the second panel 32 due to irradiation with UV light or the like can be prevented. Further, when the second panel 32 is made of an acrylic resin, the first panel 31 and the display unit 20 are bonded by irradiation with UV light or the like in a state where the second panel 32 is bonded to the first panel 31 first. If it tries to do so, the light of the wavelength of UV region will be absorbed by acrylic resin. As a result, the amount of light necessary for curing the photocuring material cannot be obtained. On the other hand, if the 2nd panel 32 is joined to the 1st panel 31 after the 1st panel 31 and the display part 20 are joined, such a thing can be prevented.

  As shown in FIG. 8, the first panel 31 may have a chamfered portion 312 at the end of the glass surface 311. The chamfered portion 312 has a chamfered shape located at a ridge between the side surface of the first panel 31 and the glass surface 311. The chamfered portion 312 is not limited to the C chamfered shape illustrated in FIG. 8, and may be another chamfered shape such as an R chamfered shape. When the first panel 31 has the chamfered portion 312, the second panel 32 is joined to the inside of the chamfered portion 312. In other words, the end of the second panel 32 is located away from the chamfered portion 312 by a predetermined distance or more.

  As shown in FIG. 9, when the end portion of the second panel 32 is overlapped with the chamfered portion 312, a part of the second adhesive material 324 of the second panel 32 is exposed. When dust or the like adheres to the second adhesive material 324, the bonding strength at the interface between the first panel 31 and the second panel 32 may be reduced. Further, when dust or the like adheres to the second adhesive material 324, appearance quality can be deteriorated. In the composite panel 30 according to the present embodiment shown in FIG. 8, the bonding strength between the first panel 31 and the second panel 32 is easily maintained as compared with the configuration shown in FIG. Further, the composite panel 30 according to the present embodiment shown in FIG. 8 is easily maintained in appearance quality as compared with the configuration shown in FIG.

  As shown in FIG. 10, the second panel 32 may overlap the position where the first panel 31 is supported by the support portion 12. The position where the first panel 31 is supported by the support portion 12 is also referred to as a fulcrum. In other words, the end of the second panel 32 may be located on the outer side closer to the rib 11 of the housing 10 than the fulcrum. The first panel 31 can receive a relatively large stress at the fulcrum. When the second panel 32 is superimposed on the fulcrum, the stress applied to the composite panel 30 at the fulcrum can also be distributed to the second panel 32. As a result, the stress applied to the composite panel 30 at the fulcrum can be relaxed.

  The second panel 32 may be damaged depending on the usage state of the electronic device 1. Even if the second panel 32 is damaged, the first panel 31 can be prevented from cracking due to the impact absorbed by the second panel 32. The second panel 32 may be replaced if it is damaged. The second panel 32 can be replaced by being configured to be peelable from the first panel 31.

  As shown in FIG. 11, the jig 33 is easily inserted into the joint between the first panel 31 and the second panel 32 in a state where the front panel 40 is removed. The second panel 32 can be peeled off by inserting a jig 33 into the joint between the first panel 31 and the second panel 32. The composite panel 30 may be configured such that the second panel 32 can be peeled off by a user's nails or the like in a state where the front panel 40 is removed. In other words, the composite panel 30 is configured to be accessible to the joint between the first panel 31 and the second panel 32 by the jig 33 or the user's claws in a state where the front panel 40 is removed. . The 1st panel 31 may be comprised so that the jig | tool 33 or a user's nail | claw etc. may slide on the 1st surface side. By doing in this way, it will become difficult to peel off the 1st panel 31 together.

  By comparing FIG. 6 with FIG. 11, the positional relationship among the first panel 31, the second panel 32, and the front panel 40 can be specified by the area where the first panel 31 is exposed on the first surface side. In FIG. 6, an exposed portion 31 a that is not covered by the second panel 32 and the front panel 40 exists on the first surface side of the first panel 31. In FIG. 11, an exposed portion 31 b that is not covered by the second panel 32 exists on the first surface side of the first panel 31 from which the front panel 40 is removed. The area of the exposed part 31b is wider than the area of the exposed part 31a. The areas of the exposed portions 31a and 31b are also referred to as exposed areas. In other words, the exposed area that is not covered by the second panel 32 when the front panel 40 is removed is the exposed area that is not covered by the second panel 32 and the front panel 40 when the front panel 40 is attached. More than the area.

  When the second panel 32 is affixed to the first panel 31, the second panel 32 is directed toward the end by a squeegee or the like so that air bubbles or foreign matter do not enter between the second panel 32 and the first panel 31. You may be pushed. By removing the front panel 40, the second panel 32 can be easily pressed toward the end by a squeegee or the like, and can be more strongly joined to the first panel 31. As a result, the second panel 32 is less likely to be unintentionally peeled from the first panel 31.

  As shown in FIG. 4, at least a part of the end portion of the front panel 40 may be provided along the end portion on the negative direction side of the Y axis of the second panel 32. When at least a part of the end portion of the front panel 40 extends along the end portion of the second panel 32, the user's fingertip or the like is not easily caught on the end portion of the second panel 32. As a result, the second panel 32 is less likely to be unintentionally peeled from the first panel 31. Visibility of characters or images displayed on the display unit 20 can be maintained when at least a part of the end of the front panel 40 extends along the end of the second panel 32.

  As shown in FIG. 6, the thickness of the end portion of the front panel 40 in the positive direction of the Y axis may be thicker than the thickness of the second panel 32. In other words, the end portion of the front panel 40 may protrude toward the front side of the housing 10 from the second panel 32. Since the end portion of the front panel 40 protrudes from the second panel 32, it becomes difficult for a user's fingertip or the like to be caught on the end portion of the second panel 32. As a result, the second panel 32 is less likely to be unintentionally peeled from the first panel 31.

  In the electronic device 1 according to another embodiment, the front panel 40 may cover at least a part of the end of the second panel 32 as shown in FIG. In other words, the joint between the first panel 31 and the second panel 32 is not exposed when the front panel 40 is attached. In a state where the front panel 40 is removed, the joint between the first panel 31 and the second panel 32 is exposed. By doing so, it is difficult for dust to adhere to or collide with objects at the end of the second panel 32. As a result, the second panel 32 is less likely to be unintentionally peeled from the first panel 31.

  The front panel 40 may cover at least a part of the end of the second panel 32 in the negative direction of the Y axis. The front panel 40 may cover at least a part of the end of the second panel 32 in the positive or negative direction of the X axis. By doing in this way, it becomes difficult for the 2nd panel 32 to peel from the 1st panel 31 unintentionally.

  The electronic device 1 according to this embodiment includes a detachable front panel 40. When the front panel 40 is attached, the second panel 32 may be difficult to be peeled unintentionally. When the front panel 40 is removed, the second panel 32 can be easily peeled off by the jig 33 or the user's nails. Since the front panel 40 is detachable, the second panel 32 can be configured to be easily peeled off as needed while being configured to be generally difficult to peel off.

(Ease of cleaning)
The electronic device 1 according to the present embodiment has a structure that prevents water or foreign matter from entering the housing 10. The electronic device 1 includes a cover portion 43 that serves as an air passage. Water or foreign matter can enter the inside of the housing 10 from the cover portion 43. The electronic device 1 includes a speaker 50 having a predetermined waterproof performance and a waterproof sheet 56 in a region covered with a cover portion 43 into which water or a foreign object can enter. Since the components disposed in the area where water can enter have a predetermined waterproof performance, the waterproof performance of the electronic device 1 as a whole can be improved.

  The waterproof sheet 56 is configured to allow air to pass through while having a predetermined waterproof performance. When the surface of the waterproof sheet 56 gets wet with water, the waterproof sheet 56 is difficult to pass air. In other words, when the surface of the waterproof sheet 56 gets wet with water, the air permeability of the waterproof sheet 56 is deteriorated. When the breathability of the waterproof sheet 56 is poor, it is difficult for sound from the outside of the housing 10 to be input to the microphone 52 covered with the waterproof sheet 56. When the air permeability of the waterproof sheet 56 is poor, the accuracy of the atmospheric pressure outside the housing 10 measured by the atmospheric pressure sensor 54 covered with the waterproof sheet 56 may be lowered.

  When the surface of the waterproof sheet 56 is wet with water, the air permeability of the waterproof sheet 56 can be recovered by drying the surface of the waterproof sheet 56. By removing the front panel 40, the surface of the waterproof sheet 56 is easily dried.

  As shown in FIG. 5, when a gap 58 exists between the cover portion 43 and the speaker 50 or the waterproof sheet 56, foreign matter that has entered the housing 10 from the cover portion 43 can remain in the gap 58. . When water containing salt such as seawater enters the inside of the housing 10 from the cover portion 43, the salt can be precipitated as crystals in the gap 58. Precipitated salt can become foreign matter remaining in the gap 58. Regardless of the presence of the gap 58, the foreign matter may remain in the air passage of the cover portion 43 or may be deposited.

  The foreign matter remaining in the gap 58 can affect the sound emitted from the speaker 50. For example, the foreign matter remaining in the gap 58 can reduce the volume of sound from the speaker 50 or change the quality of the sound. The foreign matter remaining in the gap 58 can affect the sound input to the microphone 52. For example, the foreign matter remaining in the gap 58 reduces the volume of sound input to the microphone 52 or changes the quality of the sound. The foreign matter remaining in the gap 58 can affect the atmospheric pressure measured by the atmospheric pressure sensor 54. The foreign matter remaining in the gap 58 can damage the waterproof sheet 56. When the waterproof sheet 56 is damaged, the waterproof performance of the waterproof sheet 56 deteriorates. That is, the foreign matter remaining in the gap 58 can reduce the waterproof performance of the waterproof sheet 56.

  When the electronic apparatus 1 is cleaned without removing the front panel 40, water containing a detergent can enter the inside of the housing 10. When water containing detergent enters the inside of the housing 10 from the cover portion 43, the detergent components may remain in the gap 58. When the components of the detergent remain in the gap 58, the waterproof performance of the waterproof sheet 56 may be deteriorated.

  When foreign matter remains in the gap 58, the influence exerted on the speaker 50, the microphone 52, and the atmospheric pressure sensor 54 can be reduced by removing the foreign matter by cleaning or the like. By removing the front panel 40, foreign matters remaining in the gap 58 are easily removed.

  The electronic device 1 according to this embodiment includes a detachable front panel 40. By removing the front panel 40, the waterproof sheet 56 is exposed and can be easily cleaned. As a result, the waterproof performance of the waterproof sheet 56 is easily maintained.

  You may comprise so that the space | gap 58 between the cover part 43 and the waterproof sheet 56 does not exist. In this case, the cover part 43 may be provided so as to contact the waterproof sheet 56. When the cover part 43 contacts the waterproof sheet 56, the waterproof sheet 56 may be pressed down. As a result, the waterproof sheet 56 may be difficult to peel off.
