JP 2010-278616 A

  However, in the above-described electronic device, the decorative plate and the double-sided tape are used in order to maintain the appearance design, so the number of parts increases.

  The objective of this invention is providing the electronic device comprised by few components, without impairing an external appearance.

  An electronic device according to the present invention is formed on a back surface side of the external cover, a speaker that outputs sound, an external cover that configures an external appearance, a plurality of speaker holes provided in a position of the external cover facing the speaker. And a spacer formed at a position surrounding the periphery of the speaker hole, an inner cover located on the back side of the outer cover, a recess formed on the front side of the inner cover and where the spacer is located, and the inner cover A sound passage hole formed between the speaker and the speaker hole and a vent hole formed in the concave portion of the inner cover are provided.

  According to the electronic device of the present invention, the electronic device can be configured with a small number of parts without impairing the appearance.

  A digital camera as an electronic apparatus according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a front surface of a digital camera according to an embodiment. A photographing window 4 for allowing light from a subject to enter is provided on the front surface of the digital camera 2, and a release button 6 for giving a release instruction is provided on the upper surface. The housing of the digital camera 2 includes a front cover 8 serving as a front surface portion, a back cover (not illustrated) serving as a back surface portion, and a side surface cover 10 in which an upper surface portion, a lower surface portion, and a side surface portion are integrated. The side cover 10 is sandwiched between the front cover 10 and the back cover so as to be in close contact with each other without gaps, thereby ensuring the waterproof function of the digital camera 2.

  FIG. 2 is a diagram showing an internal configuration of the digital camera according to the embodiment as viewed from the front side. Inside the digital camera 2, an image sensor 12, a power supply unit 14, a speaker unit 16, and the like are arranged. The imaging element 12 images subject light incident from the imaging window 4. The power supply unit 14 supplies power to each unit of the digital camera 2. The speaker unit 16 outputs sound based on sound data stored in a storage medium (not shown).

  An inner cover 18 is disposed on the back side of the side cover 10 of the digital camera 2. FIG. 3 is a perspective view showing a region facing the speaker unit 16 of the inner cover 18 according to the embodiment. A substantially rectangular concave portion 20 including a position facing the speaker portion 16 is formed on the surface side of the inner cover 18. A sound passage hole 22 is formed at a position of the concave portion 20 facing the speaker portion 16, and a vent hole 24 is formed at a lower portion of the concave portion 20 at a position facing the speaker portion 16.

  FIG. 4 is a perspective view showing a region facing the speaker unit 16 of the side cover 10 according to the embodiment, where (a) shows the front side of the side cover 10 and (b) shows the back side of the side cover 10. Show. The side cover 10 is provided with a plurality of speaker holes 26 at positions facing the speaker unit 16. A waterproof filter 28 is bonded to the back surface side of the side cover 10 so as to cover the speaker hole 26. In addition, a spacer 30 is formed on the back side of the side cover 10 so as to surround the waterproof filter 28 and to have an outer peripheral shape along the recess 20 of the inner cover 18. Therefore, the side cover 10 and the inner cover 18 are combined so that the outer wall portion of the spacer 30 is in contact with the inner wall portion of the recess 20 as indicated by the arrow in FIG. The waterproof filter 28 is a continuous porous filter formed of, for example, PTFE resin, and has air permeability and sound permeability while maintaining waterproofness.

  FIG. 6 is a cross-sectional view showing the structure of the side cover and the inner cover around the speaker unit according to the embodiment. Since the spacer 30 is located in the recess 20, a gap 32 is formed between the inner cover 18 and the side cover 10 in a region surrounded by the spacer 30 of the side cover 10. The gap 32 communicates with the vent hole 24 and the speaker hole 26. Accordingly, the air heated by the heat generated from the image pickup device 12 and the power supply unit 14 is discharged to the outside from the vent hole 24 through the gap 32 and the speaker hole 26 as indicated by arrows in FIG.

  Further, since the waterproof filter 28 is adhered to the back surface side of the side cover 10 so as to cover the speaker hole 26, it is possible to prevent water from entering through the speaker hole 26, and thereby the waterproof property of the digital camera 2. Is maintained.

  According to the digital camera 2 according to the present embodiment, the spacer 32 provided on the back side of the speaker hole 26 of the side cover 10 is positioned in the recess 20 provided on the surface side of the inner cover 18, so that the gap 32 is formed. Since it is formed, air heated inside the digital camera 2 is released to the outside through the vent hole 24, the gap 32, and the speaker hole 26, so that heat generated in the digital camera 2 can be dissipated. . Further, since the vent hole 24 is hidden by the side cover 10, the appearance of the digital camera 2 is not impaired. In addition, since a decorative plate, a double-sided tape, etc. for concealing the vent holes as in the prior art can be reduced, a digital camera can be configured with a small number of parts.

  In addition, since the waterproof filter 28 can prevent water from entering the digital camera 2 from the speaker hole 26, it is possible to maintain waterproofness while ensuring air permeability.

  In the above-described embodiment, the digital camera as an electronic device has been described as an example. However, the present invention is not limited to this, and the same side cover and internal cover are applied to other electronic devices such as a PDA, a mobile phone, and a game machine. Can be configured with a small number of parts without impairing the appearance. Further, by adhering the waterproof filter to the back side of the speaker hole, it is possible to prevent water from entering the electronic device from the speaker hole while ensuring air permeability.
