Abstract
The utility model relates to a dynamic microphone, and relates in particular to a direct inserting type dynamic microphone used in a severe environment. The direct inserting type dynamic microphone comprises a housing. A pin seat provided with a copper pin is fixed to a front end of the housing. A steel magnet and a pole plate are fixed in the housing through a support frame. A gasket with a vibrating diaphragm is fixed on the pole plate. A voice reception hole is provided at one side of the housing close to the vibrating diaphragm. The vibrating diaphragm and the copper pin are electrically connected with a circuit board. A ventilation hole is provided in the housing. A waterproof membrane is fixed to one side of the housing close to the ventilation hole. With the above structure, the waterproof membrane not only can prevent water, but also can well ventilate the direct inserting type dynamic microphone. When the direct inserting type dynamic microphone is used in the severe environment, the direct inserting type dynamic microphone can realize water prevention and high fidelity.
Description
Technical field
The utility model relates to a kind of moving-coil microphone, particularly a kind of direct insertion moving-coil microphone that under adverse circumstances, uses.
Background technology
The moving-coil microphone utilizes electromagnetic induction principle to make, and utilizes coil in magnetic field, and cutting magnetic induction line is converted into the signal of telecommunication with voice signal, and in general effect is relatively good.
Along with the development of society, the progress of science and technology, the extensive utilization of electronic product, electret microphone has been widely used in every field at present.But require the moving-coil microphone can waterproof when under the adverse circumstances in the world of ice and snow, using the moving-coil microphone on the one hand, will guarantee moving-coil microphone high-fidelity on the other hand.
Summary of the invention
The utility model technical issues that need to address provide a kind of direct insertion moving-coil microphone that can waterproof.
For solving above-mentioned technical problem, the waterproof construction of the direct insertion moving-coil microphone of the utility model comprises housing, and said housing front end is fixed with the pin base of band copper pin; Be fixed with magnet steel, pole plate through support in the said housing; Also be fixed with the pad of band vibrating diaphragm on the said pole plate, the side near vibrating diaphragm on the said housing has MIC, and said vibrating diaphragm, copper pin are electrically connected with circuit board; Also have air-vent on the said housing, the side near air-vent in the said housing is fixed with water-proof film.
Two side peripheries up and down of said water-proof film are provided with the water proof rubber pad, and said pad outer periphery also is provided with the water proof rubber pad.
Said housing comprises upper shell and lower house, and upper shell and lower house are fastened.
Said support is ventilative T iron.
Post damping paper on the said ventilative T iron.
After adopting said structure, water-proof film not only can waterproof, and can well breathe freely.When under adverse circumstances, using, can accomplish waterproof, high-fidelity.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the cutaway view of the utility model.
Among the figure: 1 is upper shell, and 2 is lower house, and 3 is pin base, and 4 is the copper pin, and 5 is pad, and 6 is vibrating diaphragm, and 7 is pole plate, and 8 is magnet steel, and 9 are ventilative T iron, and 10 is water-proof film, and 11 is the water proof rubber pad, and 12 are damping paper, and 13 is circuit board
Embodiment
The waterproof construction of direct insertion moving-coil microphone as shown in Figure 1 comprises housing, and housing comprises upper shell 1 and lower house 2 here.Said upper shell 1 is fastened with lower house 2, promptly on a housing, offers draw-in groove, is arranged at the convexity that draw-in groove adapts on another housing, so just can upper and lower casing be fastened.What simultaneously, upper shell 1 engaged with lower house 2 is tight, very close to each other.
Said upper and lower casing forms the pin base 3 that whole front end is fixed with band copper pin 4.Here copper pin 4 can be to be fixed on the pin base 3, also can be to be movably connected on the pin base 3.Said flexible connection is that copper pin 4 is hinged with pin base 3, has the groove that adapts with copper pin 4 on the pin base 3, can copper pin 4 be recovered in the pin base 3 like this, is convenient for carrying.No matter copper pin 4 is fixedly connected or flexibly connects with pin base 3, like this copper pin is set directly at the direct insertion moving-coil microphone of formation on the housing.
Be fixed with magnet steel 8, pole plate 7 through support in the said housing, also be fixed with the pad 5 of band vibrating diaphragm 6 on the said pole plate 7, the side near vibrating diaphragm 6 on the said lower house 2 has MIC, has so just formed the radio reception part of moving-coil microphone.Said vibrating diaphragm 6, copper pin 4 are electrically connected with circuit board 13, and circuit board 13 is fixed between vibrating diaphragm 6 and the copper pin 4.Copper pin 4 is inserted in the supply socket, and after the energising, vibrating diaphragm 6 receives voice signal cutting magnetic induction line in magnetic field, and voice signal is converted into the signal of telecommunication.
Also have air-vent on the said upper shell 1, the side near air-vent in the said upper shell 1 is fixed with water-proof film 10.Two side peripheries up and down of said water-proof film 10 are provided with water proof rubber pad 11, and said water proof rubber pad 11 is circular, along the periphery setting of water-proof film 10, can prevent that effectively sealing enters in the microphone.Water-proof film 10 belongs to pellicle character simultaneously, prevents that on the one hand water from flowing in the microphone, can well breathe freely on the other hand.
Said support posts damping paper 12 for ventilative T iron 9 on the said ventilative T iron 9, said damping paper 12 has the effect of regulating the microphone frequency response curve.
