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 mike
Technical field
The present invention relates to a kind of water-tight device, more particularly to a kind of water-tight device for mike.
Background technology
Underwater photograph technical, recording need to take waterproof measure to relevant device.At present, it will be many that traditional waterproof jacket is usually used Plant device suite together, or using special waterproof cover etc..But, while conventional waterproof is enclosed within waterproof, have impact on sound Recording quality；And special waterproof cover is relatively costly, complex structure is set with cumbersome.
The content of the invention
It is an object of the invention to provide a kind of water-tight device for mike of simple structure.
The technical solution used in the present invention is：
A kind of water-tight device for mike, including the housing for being provided with voice guide hole and rigid leading note cover plate；The rigidity Leading note cover plate is placed in the hull outside, relative with the position of the voice guide hole；The marginal portion sealing of rigid leading note cover plate connects It is connected on the housing, non-edge part and the housing of rigid leading note cover plate leave gap；Mike is placed in housing.
Preferably, the center of described rigid leading note cover plate, gap, voice guide hole and mike is point-blank.
Preferably, the rim of described rigid leading note cover plate is inwardly cast inverted L-shaped and is stretched in the point glue groove of housing setting, In point glue groove, injecting glue is hermetically connected with the shell rigid leading note cover plate.
Preferably, described rigid leading note cover plate is provided with the edge attachments for separating rigid leading note cover plate with The groove that the V-shaped groove of the V-shaped groove of septum cordis line point, the housing setting and rigid leading note cover plate matches.
Preferably, elastic seal cartridge is set below described voice guide hole, and 1 Jing elastic seal cartridges of the mike are fixed on In housing.
Preferably, described elastic seal cartridge adopts gum elastic set.
Preferably, described rigid leading note cover plate is circular foil member.
Beneficial effects of the present invention are：
1. water-tight device simple structure of the present invention for mike, seals good waterproof performance, and be placed in 60 meters of the depth of water with Upper place uses.
2. the present invention leaves gap for the water-tight device rigid leading note cover plate and the housing that adopt of mike, it is to avoid just Property leading note cover plate be subject to housing pressure and dumb sound, distorsion, volume attenuation or high pitch loss for producing etc., make the sound of recording Effect is basically identical with direct recording effect in atmosphere.
3. the rigid leading note cover plate that the water-tight device for mike of the invention is adopted is installed on the outside of housing, in water When lower, rigid leading note cover plate is subject to inside hydraulic pressure, rigid leading note cover plate to be closely connected housing with housing, be not in The phenomenon of shrinking away from theshell.
Invention description of the drawings
Fig. 1 is a kind of sectional view for implementing structure of the present invention.
Description of reference numerals：1- mikes, 2- elastic seal cartridges, 3- housings, 4- gaps, 5- voice guide holes, 6- rigidity leading notes Cover plate, 7- point glue grooves, 8-V shape grooves.
Specific embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description：
As shown in figure 1, a kind of water-tight device for mike of the present invention, which includes the housing 3 for being provided with voice guide hole 5 and just Property leading note cover plate 6；The rigid leading note cover plate 6 is placed in the outside of the housing 3, relative with the position of the voice guide hole 5；Rigidity The marginal portion of leading note cover plate 6 is sealedly attached on the housing 3, and non-edge part and the housing 3 of rigid leading note cover plate 6 leave Gap 4；The water-tight device is set on mike 1.
In the present embodiment, the center of described rigid leading note cover plate 6, gap 4, voice guide hole 5 and mike 1 is in straight line On.The rigid leading note cover plate 6 adopts rigid material, and inverted L-shaped of its rim inwardly casting is stretched in the point glue groove 7 of the setting of housing 3, The injecting glue into a glue groove 7, rigid leading note cover plate 6 is fixed on housing 3, and is made close between rigid leading note cover plate 6 and housing 3 Envelope.The rigid leading note cover plate 6 is provided with for separating the edge attachments of rigid leading note cover plate 6 and the V of center sound insulation part Shape groove 8, this configuration has improved the material stiffness of rigid leading note cover plate 6.The housing 3 arranges the V-shaped groove with rigid leading note cover plate 6 The groove for matching, it is ensured that rigid leading note cover plate 6 is stable on housing 3.Elastic seal cartridge 2, institute are set below the voice guide hole 5 State 1 Jing elastic seal cartridges 2 of mike to be fixed in housing 3, the setting of elastic seal cartridge 2 can reduce the dither of housing to wheat The impact of gram wind, reduces noise.The rigid leading note cover plate 6 is circle, using the foil of 0.3mm.
Described elastic seal cartridge can adopt gum elastic set.
Water-tight device for mike of the present invention can be made into the water-tight device of the mike for matching various models, During use, directly the device is set on mike, is removed when not using, recycled；May be made as and mike one Formula；Also can be connected with other water proof equipments or be made into integration use, for example, be made into integration with the waterproof jacket of video camera and use.
The present invention preferably embodiment is the foregoing is only, not for limiting the practical range of the present invention, as long as The equivalence changes done in protection scope of the present invention and modification, have all been deemed to fall in protection scope of the present invention.
