Embodiment Construction

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] Such as figure 1 As shown, the electronic device in a preferred embodiment of the present invention includes a housing 1 and a microphone 2 , the microphone 2 is assembled corresponding to the housing 1 , and the housing 1 is provided with a sound guide channel 7 for transmitting sound to the microphone 2 . A sealing structure 8 is provided between the microphone 2 and the housing 1 to form an airtight space A between the microphone 2 and the sound guiding channel 7 that can only be communicated with the outside world through the sound guiding channel 7, so that after water enters the sound guiding channel 7 , relying on the effect of surface tension to stay in the sound guiding channel 7 to prevent water from e...

Abstract

The invention relates to electronic equipment and a microphone waterproof structure. The microphone waterproof structure comprises a housing and a microphone. The microphone and the housing are correspondingly assembled. The housing is provided with a sound guiding channel which realizes sound transmission to the microphone. A sealing structure is arranged between the microphone and the housing, thereby forming a sealed space which can be communicated with outside only through the sound guiding channel between the microphone and the inner end of the sound guiding channel. After water enters the sound guiding channel, the water remains in the sound guiding channel by means of a surface tension, thereby preventing water entry into the sealed space through the sound guiding channel. According to the microphone waterproof structure, after the water enters the sound guiding channel, the water remains in the sound guiding channel by means of the surface tension, and the sealed space is extruded. On the condition that combination of an external pressure and a water pressure does not exceed a preset pressure, the microphone waterproof structure is a sealed container for water and air except for the sound guiding channel, thereby preventing microphone function failure caused by water entry into the sealed space.

Description

technical field [0001] The invention relates to electronic terminal equipment, and more specifically, to an electronic equipment and a microphone waterproof structure. Background technique [0002] In the design of high-level waterproof (such as IPX8) electronic products involving microphone waterproofing in the related art, a commonly used method is to use a waterproof breathable membrane (or waterproof membrane) to isolate the microphone body from the outside world. [0003] A typical profile is Figure 4 As shown (the dust-proof net irrelevant to IPX8 waterproof is omitted), the waterproof structure includes a housing 1, a microphone 2, a waterproof and breathable membrane 3, a sound guide hole 4, a sound cavity before the membrane 5, a sound cavity 6 behind the membrane, and a waterproof The membrane 3 can prevent water from entering the membrane rear sound chamber 6 and the microphone 2 through the sound guide hole 4 and the front sound cavity 5 of the membrane, so as t...
