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

[0030] Next, a first embodiment of the present invention will be described with reference to FIGS. 1 to 4 .

[0031] FIG. 1 shows a digital camera 10 as an example of an electronic device having a voice recording and playback function. The housing 11 of the digital camera 10 is provided with a lens barrel 12 including an imaging optical lens, a shutter button 13, an electronic flash 14, a viewfinder optical system 15, a microphone 16, a speaker 17, and the like.

[0032] Inside the casing 11 is accommodated a sound recording and reproducing circuit composed of electronic components (not shown in the figure) for sound recording and reproducing, and the like. This recording and reproducing circuit has functions of recording the sound input from the microphone unit 16 on a recording medium and outputting the recorded sound from the speaker unit 17 , for example. The recording medium referred to here may be a built-in memory such as a flash memory installed in the digital camera ...

Abstract

The present invention provides an electronic apparatus with a recording reproducing function which is highly waterdrop proof and has excellent sound quality. A digital camera comprises a first cover (31) with a first sound hole (21) formed at a position opposite to a microphone (25), a waterproof sheet (40) arranged to cover the first sound hole (21), a second cover (32) arranged away from the waterproof sheet (40), and a second sound hole (22) formed on the first cover (31). The second sound hole (22) is shifted and arranged on the side of a circumference of the first sound hole (21) so as not to be located on an extended line in an axial direction to the first sound hole (21). A circumference part (40a) of the waterproof sheet (40) is extended to the position opposite to the second hole (22).

Description

technical field [0001] The present invention relates to a water-proof structure of sound-emitting or sound-collecting parts used in digital cameras, portable phones, tape recorders, etc., and an electronic device with the same structure. Background technique [0002] It is desirable to have a waterproof function for sound-collecting parts such as sound-collecting parts such as speakers or microphones built into digital cameras and mobile phones with audio-recording and playback functions. The existing method used to make it waterproof is to set waterproof sheets or anti-drip sheets to cover the sound holes formed on the relative positions of the pronunciation or sound collection parts. (For example, refer to the following Patent Document 1 or 2). [0003] (Patent Document 1) JP-A-05-007390 [0004] (Patent Document 2) JP-A-10-210121 [0005] When a sound hole is provided at a position facing a speaker or a microphone, a waterproof sheet member having a certain degree of w...
