The periphery of the vibrating membrane is provided with a fixing ring of which the middle part is provided with a membrane body, a metal ring is arranged above the vibrating membrane, wherein a PCB board is arranged above the metal ring and the middle position of the lower surface of the PCB board is provided with an FET. The external surface of the metal ring is provided with an insulation layer, and the upper surface of the metal ring is in conduction with the electrical property of the PCB board.
Description
Technical field
The utility model relates to a kind of pick-up of microphone, relates in particular to a kind of pick-up that can improve the sound collecting effect.
Background technology
Microphone has become the instrument that arrives commonly used in people's live and work, and the parts that microphone is collected sound are exactly pick-up.
See also Fig. 1, pick-up generally comprises a brazen tubular cylindrical shell 7 ', the bottom of this cylindrical shell 7 ' is provided with vibrating membrane 5 ', the periphery of this vibrating membrane 5 ' is provided with the retainer ring 52 ' of the annular of stainless steel material, be provided with the film body 54 ' of plastic material in the middle of this retainer ring 52 ', this retainer ring 52 ' top pad is put the packing ring 3 ' of the annular of a plastic material, the top of this packing ring 3 ' is provided with the teething ring 2 ' of an annular, be provided with the becket 6 ' of the annular of a metal material in the inside of this teething ring 2 ', the top of this becket 6 ' is provided with a pcb board 1 ', the upper surface of this becket 6 ' and pcb board 1 ' electrically conduct, the lower surface centre position installing FET9 ' of this pcb board 1 ', a box body 8 ' is established in the outside of this FET9 ', offers some through holes (figure does not show) on the diapire of this cylindrical shell 7 ' and passes through for sound wave.Sound wave is collected by vibrating membrane 5 '.
The effect of sound collecting is subjected to the influence of area size of the film body 54 ' of vibrating membrane 5 ', if the area of film body 54 ' is big, then radio reception is effective, if film body 54 ' area is little, the radio reception effect is relatively poor relatively.Because cylindrical shell 7 ' and becket 6 ' all are that the material with electric conductivity is made, this teething ring 2 ' separates them and prevents that them from electrically conducting, this teething ring 2 ' is indispensable, this teething ring 2 ' has certain thickness, make this becket 6 ' volume inside less, the area of the film body 54 ' of this vibrating membrane 5 ' is also corresponding less, therefore has influence on the radio reception effect of whole pick-up.
Summary of the invention
Main purpose of the present utility model is to provide a kind of pick-up that can improve the sound collecting effect.For realizing above-mentioned purpose, the utility model provides a kind of pick-up, the cylindrical shell that comprises a metal material, offering some through holes on the diapire of this cylindrical shell passes through for sound wave, the bottom of this cylindrical shell is provided with a vibrating membrane, the periphery of this vibrating membrane is provided with a retainer ring, be provided with a film body in the middle of this retainer ring, the top of this vibrating membrane is provided with the becket of a metal material, the top of this becket is provided with a pcb board, a FET is installed in the lower surface centre position of this pcb board, and the outer surface of this becket is provided with a layer insulating, and the upper surface and the pcb board of this becket electrically conduct.
The utility model is with respect to prior art, the circumferential outer surface of becket is got a layer insulating, cylindrical shell and becket can electrically not conducted, played the effect of teething ring 2 ', therefore can omit teething ring 2 ', and owing to omitted the thickness of teething ring 2 ', it is big that this becket volume inside becomes relatively, it is big that the area of the film body of this vibrating membrane also becomes relatively, so the radio reception effect of pick-up is better relatively.

Fig. 2 is the cutaway view of the utility model pick-up.
Embodiment
See also Fig. 2, a kind of pick-up comprises a brazen tubular cylindrical shell 7.
The bottom of this cylindrical shell 7 is provided with a vibrating membrane 5, and the periphery of this vibrating membrane 5 is provided with the retainer ring 52 of the annular of stainless steel material, is provided with the film body 54 of plastic material in the middle of this retainer ring 52.
These retainer ring 52 top pads are put the packing ring 3 of the annular of a plastic material.
The top of this packing ring 3 is provided with the becket 6 of the annular of a metal material, and this becket 6 is dipped in the insulating varnish, adopts centrifugation method to obtain the even and thin insulating barrier 62 of one deck on the circumferential outer surface of this becket 6 then.And the insulating varnish polishing of this becket both ends of the surface about in the of 6 is removed, and can conduct electricity.
The top of this becket 6 is provided with a pcb board 1, and the upper surface and the pcb board 1 of these becket 6 polishings electrically conduct, the lower surface centre position installing FET9 of this pcb board 1, and a box body 8 is established in the outside of this FET9.
Offering some through holes (figure does not show) on the diapire of this cylindrical shell 7 passes through for sound wave.Sound wave is collected by vibrating membrane 5.
Because the utility model is with respect to prior art, the circumferential outer surface of becket 6 is got a layer insulating 62, cylindrical shell 7 and becket 6 can electrically not conducted, played the effect of teething ring 2 ', therefore can omit teething ring 2 ', and owing to omitted the thickness of teething ring 2 ', it is big that these becket 6 volume inside become relatively, it is big that the area of the film body 54 of this vibrating membrane 5 also becomes relatively, so the radio reception effect of pick-up is better relatively.
