Abstract
The utility model relates to a dynamic microphone, and relates in particular to a direct inserting type dynamic microphone of a small size. 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 circuit boards. A contracted plug-in board is fixed in the housing. The contracted plug-in board is provided with a groove. The circuit boards are fixed in the groove. With the above structure, the internal space of the microphone is greatly saved. With the direct inserting type design, the direct inserting type moving-coil microphone can be used when the contracted plug-in board is inserted, and the operation is simple and convenient.
Description
Technical field
The utility model relates to a kind of moving-coil microphone, particularly a kind of small direct insertion moving-coil microphone.
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.Present moving-coil microphone adopts the design of traditional external circuit plate, and it is big to take up room.The direct insertion moving-coil microphone that needs now a kind of small, compact conformation.
Summary of the invention
The utility model technical issues that need to address provide a kind of direct insertion moving-coil microphone of small, compact conformation.
For solving above-mentioned technical problem; The embedded lines plate 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, is 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; Side near vibrating diaphragm on the said housing has MIC, and said vibrating diaphragm, copper pin are electrically connected with wiring board, and said housing internal fixation has the contraction plug-in unit; Said contraction plug-in unit has groove, and said wiring board is fixed in the groove.
Said contraction plug-in unit is processed by ABS plastic.
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, shrink on the plug-in unit, will shrink the plug-in unit compression earlier and be inserted in the groove of housing, shrink plug-in unit then, be fixed in the housing automatically because of elastic dilatation because wiring board is fixed on.The inner space of adopting Embedded wiring board design to replace traditional external circuit plate design to practice thrift microphone greatly like this.Adopt the direct insertion design can plug and play, simple to operation.
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.
Fig. 2 is the structural representation of the utility model embedded lines plate.
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 are damping paper, and 11 for shrinking plug-in unit, and 12 is wiring board
Embodiment
Said housing comprises upper shell and lower house, and upper shell and lower house are fastened.
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, the copper pin is set directly to form direct insertion moving-coil microphone on the housing like this, and plug and play, easy to use.
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 housing internal fixation has the plug-in unit 11 of contraction, and said contraction plug-in unit 11 has groove, and said wiring board 12 is bonded in the groove.Said contraction plug-in unit 11 is processed by ABS plastic, shrinks plug-in unit 11 like this and has elasticity, collapsible.During installation, plug-in unit 11 is shunk in compression, is inserted in the draw-in groove of enclosure interior, unclamps then, shrinks plug-in unit 11 and can automatically restore to original state, thereby be able to fix.Practice thrift the inner space of microphone so greatly, made the more compact structure of microphone.
Said vibrating diaphragm 6, copper pin 4 are electrically connected with wiring board 12.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.
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.
Certainly, the contraction plug-in unit 11 of the utility model also can adopt other toughness materials that is suitable for, and such conversion all drops within the protection range of the utility model.
