  As shown in FIG. 3, 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. 3, a microphone 52 and an atmospheric pressure sensor 54 covered with a waterproof sheet 56 are located between 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.

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.

  2 and 3, 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.

(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. 3, 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 portion covered with the front panel 40 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.

(Securing the sound path)
The electronic device 1 according to the present embodiment has ribs 11 around the first surface of the housing 10. The rib 11 protrudes in the positive direction of the Z axis from the touch panel 30. Since the rib 11 protrudes in the positive direction of the Z axis, the impact in the Z axis direction on the touch panel 30 can be reduced. The rib 11 may protrude at a uniform height at each part around the first surface of the housing 10. Since the rib 11 protrudes at a uniform height, the impact on the touch panel 30 can be further reduced.

  In the case where the rib 11 protrudes at a uniform height, when the electronic device 1 is placed so that the first surface is faced down to a surface such as a floor surface or a desk surface, the electronic device 1 is placed on the rib 11. It can contact the entire surface of the first surface with respect to the surface. As shown in FIG. 3, the electronic device 1 according to the present embodiment includes a convex portion 41 of the front panel 40 that protrudes larger than the rib 11 in the positive direction of the Z-axis direction.

  As shown in FIG. 4, when the electronic device 1 is placed on the placement surface 80 so that the first surface is turned down, the convex portion 41 protrudes larger than the rib 11, so that a part of the rib 11 is formed. It leaves | separates from the mounting surface 80. When a part of the rib 11 is separated from the placement surface 80, a sound transmission path between the outside of the housing 10 and the speaker 50 or the microphone 52 can be secured.

  In the electronic device 2 according to the comparative example illustrated in FIG. 5, it is assumed that the rib 11 protrudes in the positive direction of the Z axis from the convex portion 41. When the electronic device 2 according to the comparative example is placed on the placement surface 80 so that the first surface is turned down, the rib 11 contacts the placement surface 80 over the entire circumference of the first surface. When the entire circumference of the rib 11 contacts the mounting surface 80, it is difficult to secure a sound transmission path between the outside of the housing 10 and the speaker 50 or the microphone 52. That is, when the rib 11 is in contact with the entire surface of the first surface, sound emitted from the speaker 50 is difficult to be output to the outside of the housing 10 and sound from the outside of the housing 10 is input to the microphone 52. It becomes difficult to be done.

  In the electronic apparatus 1 according to this embodiment, the convex portion 41 of the front panel 40 protrudes larger than the rib 11. When the convex portion 41 protrudes, a sound transmission path between the speaker 50 and the microphone 52 is more easily secured when the electronic device 1 is placed face down than when the convex portion 41 does not protrude. As a result, the sound emitted from the speaker 50 is easily output to the outside of the housing 10, and the sound from the outside of the housing 10 is easily input to the microphone 52.

  The convex portion 41 of the front panel 40 may be configured symmetrically with respect to a line along the longitudinal direction of the first surface of the housing 10. The electronic device 1 placed face down on the placement surface 80 is supported by the rib 11 positioned on the positive direction side of the Y axis and the convex portion 41 positioned on the negative direction side of the Y axis. When the convex portion 41 is configured to be line-symmetric with respect to a line along the longitudinal direction of the first surface, at least a part of the rib 11 located on the positive direction side of the Y axis and at least two points of the convex portion 41 are Contact the mounting surface 80. As a result, the posture of the electronic device 1 placed on the mounting surface 80 can be stabilized. The rib 11 positioned on the positive direction side of the Y axis may be configured to contact the placement surface 80 in line symmetry with respect to a line along the longitudinal direction of the first surface of the housing 10.

  The convex portion 41 of the front panel 40 may be provided in the vicinity of the speaker 50 or the microphone 52. Providing the convex portion 41 in the vicinity of the speaker 50 or the microphone 52 facilitates securing a sound transmission path between the outside of the housing 10 and the speaker 50 or the microphone 52. As a result, the sound emitted from the speaker 50 is easily output to the outside of the housing 10, and the sound from the outside of the housing 10 is easily input to the microphone 52.

  The convex portion 41 of the front panel 40 may be provided in the vicinity of the atmospheric pressure sensor 54. By providing the convex portion 41 in the vicinity of the atmospheric pressure sensor 54, an air passage between the outside of the housing 10 and the atmospheric pressure sensor 54 is easily secured. As a result, the accuracy of the atmospheric pressure outside the housing 10 measured by the atmospheric pressure sensor 54 can be improved.
