In the first casing 21 and the second casing 22, for example, the gap is sealed with a sealing member, an adhesive, or the like, and thereby the waterproof space 10 is sealed. The housing 2 incorporates various electronic components 3 that realize functions as a mobile terminal of the mobile electronic device 1 in the internal waterproof space 10 to waterproof the electronic components 3. The portable electronic device 1 includes, for example, a control unit 9, a main body member 53 of the sub display 52, a main body member 55 of the main display 51, and the like as the electronic components 3 to be waterproofed. The main body member 53 of the sub display 52 and the main body member 55 of the main display 51 are built in the waterproof space 10 inside the first housing 21 and are waterproofed. The control unit 9 is built in a waterproof space inside the second housing 22 and is waterproofed.

  Since the portable electronic device 1 has a waterproof structure as described above, and the inside of the case 2 has high sealing performance, as shown in FIGS. 4, 5, and 6, the case 2 An adjustment unit 100 is provided to adjust the pressure difference between the internal atmospheric pressure and the external atmospheric pressure.

  And the adjustment part 100 of this embodiment has the communicating path 101 and the film | membrane 102, and the communicating path 101 is a boundary of the 1st member which comprises the housing | casing 2, and the 2nd member adjacent to this 1st member. By being provided in, the internal pressure of the housing | casing 2 can be adjusted appropriately.

  The adjustment part 100 of this embodiment is demonstrated as what is provided in the 1st housing | casing 21 as an example. The communication path 101 communicates the waterproof space 10 inside the first housing 21 forming the housing 2 with the outside of the first housing 21. The communication path 101 has an external opening 103 that opens to the outside of the first housing 21 and an internal opening 104 that opens to the inside of the first housing 21. In the communication path 101, air (gas) can flow from the external opening 103 side to the internal opening 104 side or from the internal opening 104 side to the external opening 103 side.

  The communication path 101 of the present embodiment is provided at the boundary between the housing member 23 as the first member and the main body member 53 and the cover member 54 as the second member adjacent to the housing member 23. The housing member 23 is a member that constitutes the first housing 21, and more specifically, a front case 23 </ b> A that constitutes the front surface 21 </ b> A of the first housing 21 and a back surface 21 </ b> B of the first housing 21. The rear case 23B is included. That is, here, the casing member 23 constituting the first casing 21 is divided into a front case 23A constituting the front face 21A and a rear case 23B constituting the rear face 21B in the thickness direction. The front case 23A and the rear case 23B are engaged with each other so that a gap between them is a watertight structure. As described above, the main body member 53 and the cover member 54 constitute a part of the display device 5 that is an exposed component, here, the sub display 52.

  Here, the communication path 101 is provided at the boundary between the rear case 23B as the first member, the main body member 53, and the cover member 54. In other words, the communication path 101 is partitioned by the rear case 23B, the main body member 53, and the cover member 54. . That is, the communication path 101 is provided around the sub display 52 that is an exposed part. In the communication path 101, the external opening 103 on the outside of the housing is provided on the surface opposite to the closing surface of the first housing 21, that is, the back surface 21B. The external opening 103 covers the rear case 23B. It is provided so as to extend along the boundary with the member 54 (see FIG. 4). The external opening 103 of the communication path 101 extends along the edge of the cover member 54 of the sub display 52.

  The communication path 101 is provided on the side opposite to the receiver 8 with the sub display 52 as an exposed part interposed therebetween, and the internal opening 104 is provided on the side opposite to the receiver 8 with the sub display 52 interposed therebetween (FIG. 5, FIG. (See FIG. 6). In other words, the communication path 101 is provided on the opposite side of the receiver 8 with the main body member 53 and the cover member 54 being the second members interposed therebetween. As a result, the internal opening 104 of the communication path 101 is provided at a position relatively distant from the receiver 8 that is an acoustic device.

  The film 102 is provided so as to cover the internal opening 104 of the communication path 101. The film 102 does not transmit a liquid such as water and transmits a gas such as air. For example, a porous film, a microporous film, or a microporous structure material is used. The end of the membrane 102 is watertightly attached to the inner wall surface of the housing member 23 or the back surface of the main body member 53 of the sub display 52 with a waterproof tape 105 or the like. The adjustment unit 100 adjusts the internal pressure of the first housing 21 by separating the waterproof space 10 inside the first housing 21 from the outside with the membrane 102 as a boundary.

  The portable electronic device 1 configured as described above is adjusted according to the pressure difference when a pressure difference occurs between the internal pressure and the external pressure of the first housing 21 according to, for example, a change in the external environment. Air flows from the external opening 103 side to the internal opening 104 side, or from the internal opening 104 side to the external opening 103 side, whereby air flows in the waterproof space 10 inside the first housing 21. The pressure is adjusted to be equal to the external pressure. At this time, when the air flows through the communication path 101 from the external opening 103 side to the internal opening 104 side, the adjusting unit 100 causes the membrane 102 to circulate the air while not allowing the water to flow. The pressure difference between the inside and outside of the first housing 21 can be eliminated by adjusting the pressure of the waterproof space 10 inside the first housing 21 while preventing water from entering the waterproof space 10 inside the housing 21.

  The adjusting unit 100 is configured such that the communication path 101 is provided at the boundary between the rear case 23B, the main body member 53, and the cover member 54. Can be assimilated with the boundary line, and can be arranged at a position that is difficult to visually distinguish. Therefore, the adjustment part 100 can make the external opening 103 of the communication path 101 visually inconspicuous compared with the case where a through-hole is provided in the housing member 23 and used as the communication path, for example. Therefore, the design can be improved.

  More specifically, the adjustment unit 100 is provided with the communication path 101 around the sub display 52 and the external opening 103 extending along the boundary between the rear case 23B, the main body member 53, and the cover member 54. Even if the opening area of the external opening 103 and the passage area of the communication passage 101 are relatively large, the communication passage 101 can be visually inconspicuous, so that the pressure adjustment performance is improved while ensuring the design. be able to. That is, the adjustment unit 100 can suppress the deterioration of the design even if the opening area of the external opening 103 or the passage area of the communication path 101 is relatively increased in order to ensure good pressure regulation performance. it can.

  That is, the adjustment unit 100 sets the opening area and the passage area relatively large while visually assimilating the communication path 101 with the boundary line between the rear case 23B, the main body member 53, and the cover member 54. The pressure loss when passing through the communication path 101 can be suppressed, and the effective area of the membrane 102 for adjusting the internal pressure can be secured relatively large. As a result, the adjusting unit 100 can improve the followability and responsiveness of the internal pressure in the waterproof space 10 of the first housing 21 with respect to fluctuations in the external pressure of the first housing 21, and the first housing in a short time. The pressure inside the body 21 can be adjusted to an appropriate pressure.

  Thereby, the portable electronic device 1 can suppress the occurrence of problems such as low sound and distortion when an acoustic device such as the receiver 8 is operating, for example. For example, the portable electronic device 1 is a device that is affected by atmospheric pressure when it is pressed from the outside, or when the internal atmospheric pressure rises in water, at a high place, in the aircraft, etc. until the atmospheric pressure adjustment finishes functioning For example, in an acoustic device such as the receiver 8, the problem that the diaphragm receives an acoustic load due to the atmospheric pressure can be reduced, and adverse effects on the acoustic device can be suppressed.

  In addition, the adjustment unit 100 can visually assimilate the communication path 101 with the boundary line between the rear case 23B, the main body member 53, and the cover member 54. Since the communication path 101 can be made inconspicuous without providing a separate member, both the design and pressure regulation performance can be achieved while suppressing the number of parts constituting the portable electronic device 1 and suppressing an increase in manufacturing cost. can do.

  Furthermore, the adjustment unit 100 can provide the external opening 103 of the communication path 101 at the boundary between the rear case 23B, which is an opaque member, and the cover member 54, which is a transparent member. The boundary line between the case 23B, the main body member 53, and the cover member 54 can be visually assimilated.

  And since the external opening 103 of the communicating path 101 is provided in the back surface 21B of the 1st housing | casing 21, the 1st housing | casing 21 and the 2nd housing | casing 22 became the closed position in the portable electronic device 1, for example Even in such a state, the external opening 103 can be configured not to be closed, so that the pressure inside the first housing 21 can be more reliably adjusted by the adjusting unit 100. Moreover, since the external opening 103 is provided in the back surface 21B side of the 1st housing | casing 21, the portable electronic device 1 can make the communicating path 101 visually inconspicuous also in this point.

  Furthermore, since the internal opening 104 of the communication path 101 is provided on the opposite side of the receiver 8 across the sub-display 52, the portable electronic device 1 has a sufficient interval between the internal opening 104 and the receiver 8 that is an audio device. Can be secured. As a result, the portable electronic device 1 can prevent, for example, the air from the internal opening 104 from reaching the vicinity of the receiver 8 that is the acoustic device. For example, the air from the internal opening 104 is received by the receiver 8. It is possible to suppress the sound pressure from deteriorating by canceling the sound emitted from the sound.

  As a result, the portable electronic device 1 can achieve both design and pressure regulation performance, and can appropriately adjust the internal pressure of the housing 2. In other words, since the portable electronic device 1 places importance on design, it is possible to prevent the adjustment unit 100 from exhibiting sufficient pressure regulation performance.
