Description
Technical field
It the utility model is related to a kind of microphone sound pick-up outfit；A kind of more particularly to goldleaf belt sound head.
Background technology
Microphone is divided to two kinds：One kind is：Moving-coil type, Yi Zhongshi：Condenser type.Moving-coil type sound head must be born because of vibrating membrane
Carry than more than hundred times of the voice coil loudspeaker voice coil of itself weighing, it is impossible to use it is too frivolous, so big thousand times of the gross weight specific capacitance formula of vibrating membrane with
On.And condenser type sound head uses thickness about DYN dynamic less than 1/10th, ultra-thin of the gross weight about below one thousandth shakes
Dynamic film directly senses sound press, shows extremely superior physical characteristic.And as audience requires the tonequality of sound more and more higher, it is desirable to
Higher sound-reducing effect, existing microphone are increasingly difficult to meet to require.
The content of the invention
The purpose of this utility model is to provide a kind of goldleaf belt sound head, and sound-reducing effect is good, and tonequality is high, meets higher
Requirement.
The purpose of this utility model is achieved through the following technical solutions：
A kind of goldleaf belt sound head, including：Two panels stainless steel cloth 1,2, two blocks of magnet steel 3 of magnetic loop and ribbon of gold foil 5；Two pieces
Magnet steel 3 is fixed at left and right sides of the inner chamber of magnetic loop 2, and the both ends of ribbon of gold foil 5 are individually fixed in the both ends of magnetic loop 2, mid portion ripple
Shape is placed in the gap 4 between two blocks of magnet steel 3；Two panels stainless steel cloth 1 is respectively arranged on the upper and lower surface of magnetic loop 2.
The described both ends of ribbon of gold foil 5 are respectively clamped by two block pressur plates 6 and fixed by two brass screws 7.
Two blocks of described magnet steel 3 are bonded and fixed at left and right sides of the inner chamber of magnetic loop 2.
Described two panels stainless steel cloth 1 is pasted on the upper and lower surface of magnetic loop 2 respectively.
A kind of goldleaf that the utility model embodiment provides it can be seen from above-mentioned technical scheme provided by the utility model
Belt sound head, sound-reducing effect is good, and tonequality is high, meets higher requirement.
Brief description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme of the utility model embodiment
The accompanying drawing used is briefly described, it should be apparent that, drawings in the following description are only some implementations of the present utility model
Example, on the premise of not paying creative work, can also be according to these accompanying drawings for one of ordinary skill in the art
Obtain other accompanying drawings.
Fig. 1 is the dimensional structure diagram for the goldleaf belt sound head that the utility model embodiment provides；
Fig. 2 is the configuration schematic diagram for the goldleaf belt sound head that the utility model embodiment provides.
Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, it is fully described by, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole realities
Apply example.Based on embodiment of the present utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment obtained, belongs to the scope of protection of the utility model.
The utility model embodiment is described in further detail below in conjunction with accompanying drawing.
As shown in Figures 1 and 2, a kind of goldleaf belt sound head, include in structure：Two panels stainless steel cloth 1, magnetic loop 2, two
Block magnet steel 3 and ribbon of gold foil 5；Two blocks of magnet steel 3 are fixed at left and right sides of the inner chamber of magnetic loop 2, and specific two blocks of described magnet steel 3 are bonded
It is fixed at left and right sides of the inner chamber of magnetic loop 2, gap 4 is left in centre.The both ends of ribbon of gold foil 5 are individually fixed in the both ends of magnetic loop 2, specifically
The described both ends of ribbon of gold foil 5 respectively clamped by two block pressur plates 6 and fixed by two brass screws 7, four M2 × 6 can be used
Screw.The size of pressing plate 6 may be of different sizes by the limitation of structure space, and the mid portion corrugated of ribbon of gold foil 5 is placed in two blocks of magnetic
In gap 4 between steel 3；Two panels stainless steel cloth 1 is respectively arranged on the upper and lower surface of magnetic loop 2, specific described two panels stainless steel
Silk screen 1 is respectively by tape-stripping in the front and bottom surface of the upper and lower surface of magnetic loop 2, that is, magnetic loop 2.
It can be seen that goldleaf belt sound head of the present utility model, ribbon of gold foil 5 does cutting magnetic line movement in magnetic field can produce electricity
Can, we are exactly to be placed in originally with a very thin ribbon of gold foil 5 in magnetic field using this, and ribbon of gold foil is pushed to by voice signal
5 move and are converted to electric signal.Preferably go to complete this acoustic-electric transfer process by the superpower conductive capability of ribbon of gold foil 5.It is logical
It is very warm to cross the sound that this sound head restores.
The electric signal output port of this goldleaf belt sound head is exactly the both ends of ribbon of gold foil 5, so its output impedance is very
It is low, to match somebody with somebody professional audio transformer to improve its output impedance, audio-frequency transformer input is directly connected to the two of ribbon of gold foil 5
End, the output end of audio-frequency transformer may be coupled to 2pin on XLR CANNONs, on 3pin pins.Words are connected to by CANNON line again
Can reappears perfect tonequality on cylinder amplifier or sound console.XLR is commonly called as CANNON joint.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should
It is defined by the protection domain of claims.
