Abstract

The invention provides a waterproof device for a microphone. The waterproof device for the microphone is characterized by comprising a shell and a rigid voice guiding cover plate, wherein a voice guiding hole is formed in the shell; the rigid voice guiding cover plate is arranged on the outer side of the shell, and is opposite to the voice guiding hole; the edge part of the rigid voice guiding cover plate is connected onto the shell in a sealing manner; a gap is formed between the non-edge part of the rigid voice guiding cover plate and the shell; the waterproof device is coated on the microphone. The waterproof device has simple structure, good sealing and water-proof properties and good voice recording effect, and can be used in water 60m or more below the water surface.

Description

A kind of water-tight device for microphone
Technical field
The present invention relates to a kind of water-tight device, relate in particular to a kind of water-tight device for microphone.
Background technology
Underwater photograph technical, recording need to be taked waterproof measure to relevant device.At present, conventionally use traditional waterproof jacket that plurality of devices is set in together, or use special-purpose waterproof cover etc.But, when conventional waterproof is enclosed within waterproof, affected the quality of recording of sound; And special-purpose waterproof cover cost is higher, complex structure, suit complex operation.
Summary of the invention
The object of this invention is to provide a kind of water-tight device for microphone simple in structure.
The technical solution used in the present invention is:
For a water-tight device for microphone, comprise the housing and the rigidity leading note cover plate that have voice guide hole; Described rigidity leading note cover plate is placed in described hull outside, relative with the position of described voice guide hole; The marginal portion of rigidity leading note cover plate is sealedly attached on described housing, and non-marginal portion and the housing of rigidity leading note cover plate leave gap; Microphone is placed in housing.
Preferably, the center of described rigidity leading note cover plate, gap, voice guide hole and microphone point-blank.
Preferably, the rim of described rigidity leading note cover plate is inwardly cast inverted L-shaped and is stretched in the some glue groove that housing arranges, and in some glue groove, injecting glue makes rigidity leading note cover plate be connected with housing seal.
Preferably, described rigidity leading note cover plate is provided with for separating the edge standing part of rigidity leading note cover plate and the V-shaped groove of center sound insulation part, the groove that the V-shaped groove of described housing setting and rigidity leading note cover plate matches.
Preferably, described voice guide hole below arranges elastic seal cartridge, and described microphone 1 is in elastic seal cartridge is fixed on housing.
Preferably, described elastic seal cartridge adopts elastic caoutchouc cover.
Preferably, described rigidity leading note cover plate is circular foil member.
Beneficial effect of the present invention is:
1. the present invention is simple in structure for the water-tight device of microphone, and water-tight is good, and can be placed in 60 meters of above place uses of the depth of water.
2. the present invention leaves gap for rigidity leading note cover plate and the housing of the water-tight device employing of microphone, the dumb sound of having avoided rigidity leading note cover plate to be subject to the pressure of housing and having produced, distorsion, volume decay or high pitch loss etc., make the sound effect recorded basically identical with direct recording effect in air.
3. the present invention is installed on the outside of housing for the rigidity leading note cover plate of the water-tight device employing of microphone, and under water time, rigidity leading note cover plate is subject to inside hydraulic pressure, and rigidity leading note cover plate is more closely connected housing with housing, there will not be the phenomenon of shrinking away from theshell.

Fig. 1 is a kind of cutaway view of implementing structure of the present invention.
Description of reference numerals: 1-microphone, 2-elastic seal cartridge, 3-housing, 4-gap, 5-voice guide hole, 6-rigidity leading note cover plate, 7-point glue groove, 8-V shape groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail:
As shown in Figure 1, a kind of water-tight device for microphone of the present invention, it comprises housing 3 and the rigidity leading note cover plate 6 that has voice guide hole 5; Described rigidity leading note cover plate 6 is placed in the outside of described housing 3, relative with the position of described voice guide hole 5; The marginal portion of rigidity leading note cover plate 6 is sealedly attached on described housing 3, and non-marginal portion and the housing 3 of rigidity leading note cover plate 6 leave gap 4; Described water-tight device is set on microphone 1.
In the present embodiment, the center of described rigidity leading note cover plate 6, gap 4, voice guide hole 5 and microphone 1 point-blank.Described rigidity leading note cover plate 6 adopts rigid materials, and its rim is inwardly cast inverted L-shaped and stretched in the some glue groove 7 that housing 3 arranges, and to an interior injecting glue of glue groove 7, rigidity leading note cover plate 6 is fixed on housing 3, and makes to seal between rigidity leading note cover plate 6 and housing 3.Described rigidity leading note cover plate 6 is provided with for separating the edge standing part of rigidity leading note cover plate 6 and the V-shaped groove 8 of center sound insulation part, and this structure has improved the material stiffness of rigidity leading note cover plate 6.The groove that the V-shaped groove of described housing 3 settings and rigidity leading note cover plate 6 matches, guarantees that rigidity leading note cover plate 6 is stable on housing 3.Described voice guide hole 5 belows arrange elastic seal cartridge 2, and described microphone 1 is in elastic seal cartridge 2 is fixed on housing 3, and the setting of elastic seal cartridge 2 can reduce the impact of the dither of housing on microphone, reduce noise.Described rigidity leading note cover plate 6 is circular, adopts the sheet metal of 0.3mm.
Described elastic seal cartridge can adopt elastic caoutchouc cover.
Water-tight device for microphone of the present invention can be made into the water-tight device of the microphone of the various models of coupling, during use, directly this device is set on microphone, while not using, takes off, and recycles; Also can be made into and microphone integral type; Also can be connected with other water proof equipments or be made into integration use, for example, be made into integration use etc. with the waterproof jacket of video camera.
The foregoing is only preferably execution mode of the present invention, be not used for limiting practical range of the present invention, the equivalence of in every case doing in protection scope of the present invention changes and modifies, and all should think and fall in protection scope of the present invention.
