Electronic device and image pickup device

Abstract

The invention provides an electronic device and a camera device, deterioration of sound properties can be prevented even in the event that inner pressure within a frame is increased owing to heating-up of electronic components within the frame. A digital camera (1) includes: a front cover (2a), a back cover (2b) including watertight structures as the frame; a camera element (6), ASIC (8) configured within the frame as heating components; a loudspeaker (9) configured within the frame; a sound hole (2d) for passing the sound from the loudspeaker (9) to outside of the frame; a non-air permeable watertight component, which is a loudspeaker watertight slice (22), which can elastically deform and cover the sound hole (2d); and a clapboard (24) for separating the loudspeaker (9) within the frame, on account of the separation of the loudspeaker (9), protrusion of the loudspeaker watertight slice (22) can be avoided and reduction of the sound-making performance can be inhibited even under a condition that the inner pressure within the frame is increased as a result of heat of the heating components.

Description

technical field [0001] The present invention relates to an electronic device or an imaging device having a waterproof structure and having a sound generating unit (speaker) or a sound collecting unit (microphone). Background technique [0002] Conventionally, electronic devices having a waterproof structure that can be used in water or rain are generally known. Such an electronic device incorporates a microphone as a sound collecting unit or a speaker as a sound producing unit. [0003] For example, the electronic device disclosed in Patent Document 1 has a structure in which a microphone is covered with an air-permeable waterproof sheet, or a sound hole of a speaker is covered with an air-permeable waterproof sheet. [0004] Figure 9 A vertical cross-section of the main part (including the periphery of the microphone) of the electronic device of Patent Document 1 is shown. A sound hole 52a is provided in the housing 52 of the electronic device 51, and a microphone 55 is ...

AI Technical Summary

Problems solved by technology

However, in the case of the air-impermeable sheet with high waterproof performance, when the internal pressure of the frame rises, it takes time to disperse the internal pressure to the outside, and the desired effect cannot be obtained until the internal pressure is radiated to the outside. Problems with sound characteristics

[0011] For example, when the above Figure 9 When the temperature inside the housing of the electronic device 51 rises, such as Figure 10 As shown in the figure showing the state around the microphone 55, the air-impermeable sheet, that is, the microphone waterproof sheet 54 bulges, and becomes in a state where it is difficult to vibrate, causing problems in sound transmission.
