Problems solved by technology

However, the problem is that if the thickness of the sheet parts with high water resistance is increased, the air permeability will deteriorate, and the sound quality characteristics of the pronunciation and sound collection parts will deteriorate accordingly.
That is, in order to improve water resistance, it is necessary to increase the thickness of the sheet member, or to reduce the aperture diameter of the micropores formed on the porous sheet, which will deteriorate the sound quality characteristics of the sound emitting or sound collecting member.

Embodiment Construction

[0029] Refer to Figure 1 to Figure 4 The first embodiment of the present invention will be described.

[0030] Fig. 1 shows a digital camera 10 as an example of an electronic device having a sound recording and reproducing function. The housing 11 of the digital camera 10 is provided with a lens barrel portion 12 including an optical lens for imaging, a shutter button 13, an electronic flash 14, a viewfinder optical system 15, a microphone portion 16, a speaker portion 17, and the like.

[0031] A recording and reproducing circuit composed of electronic components (not shown in the figure) for sound recording and reproducing is contained in the inside of the casing 11. The recording and reproducing circuit has, for example, a function of recording the sound input from the microphone unit 16 on a recording medium and outputting the recorded sound from the speaker unit 17. The recording medium mentioned here may be a built-in memory such as a flash memory installed in the digital c...

Abstract

The invention provides an electronic device with high water resistance and good sound quality recording and playback functions. The digital camera includes: a first cover (31) having a first sound hole (21) formed at a position facing the microphone (25); a waterproof sheet (40) arranged to cover the first sound hole (21) ; a second cover (32) disposed separately from the waterproof sheet (40); and a second sound hole (22) formed in the first cover (31). The second sound hole (22) is dislocated on the outer periphery of the first sound hole (21), so that it is not located on the extension line of the axis direction of the first sound hole (21). The outer peripheral portion (40a) of the waterproof sheet (40) extends to a position facing the second sound hole (22).

Description

Technical field [0001] The present invention relates to a water-proof structure of sound-producing or sound-collecting parts used in digital cameras, mobile phones, voice recorders, etc., and an electronic device having the structure. Background technique [0002] For digital cameras and mobile phones with recording and reproducing functions, sound-producing parts such as speakers, or sound-collecting parts such as microphones, are desired to be waterproof. The existing method used to make it have a waterproof function is to provide a waterproof sheet or a drip-proof sheet to cover the sound hole formed at a position opposite to the sound generating or sound collecting component. (For example, refer to Patent Document 1 or 2 below). [0003] (Patent Document 1) JP 05-007390 A [0004] (Patent Document 2) JP 10-210121 A [0005] When a sound hole is provided at a position opposite to a speaker or a microphone, a waterproof sheet member having a certain degree of water resistance i...
