The microphone device of correlation technique generally includes vibrational system and magnetic circuit system.Vibrational system comprises vibrating diaphragm and drives the voice coil loudspeaker voice coil of vibrating diaphragm, and magnetic circuit system comprises magnetic bowl and is located at the magnetic steel component in magnetic bowl.Magnetic steel component becomes magnetic gap with magnetic bowl-type, and one end of voice coil loudspeaker voice coil is suspended in this magnetic gap.Voice coil loudspeaker voice coil is entwined by wire, and it has inlet wire and outlet.The microphone device of this structure, because magnetic gap is extremely narrow and small, in diaphragm oscillations process, inlet wire and the outlet of voice coil loudspeaker voice coil easily encounter lower plate, cause microphone device to produce noise, sensitivity decrease.
Therefore, be necessary that the microphone device studying a kind of new construction solves above-mentioned defect.
[utility model content]
For the above-mentioned defect of prior art, the utility model provides a kind of inlet wire of voice coil loudspeaker voice coil and outlet can not encounter the microphone device of lower plate.
The utility model solves the technical scheme that its technical problem adopts: construct a kind of microphone device, its involving vibrations system and magnetic circuit system, described vibrational system comprises vibrating diaphragm and drives the voice coil loudspeaker voice coil of described diaphragm oscillations, described magnetic circuit system comprises lower plate, be located at the magnetic steel component on described lower plate, described magnetic circuit system is provided with magnetic gap, described voice coil loudspeaker voice coil is suspended in described magnetic gap at least partly, described voice coil loudspeaker voice coil is provided with inlet wire and outlet near one end of described lower plate, described lower plate is respectively equipped with the relief portion for dodging described inlet wire and outlet in the position corresponding with described inlet wire and outlet.
Preferably, described relief portion is the groove that described lower plate is recessed to form along the direction away from described voice coil loudspeaker voice coil.
Preferably, described relief portion comprises the first relief portion for dodging described inlet wire and the second relief portion for dodging described outlet, and described first relief portion and described second relief portion are that diagonal angle is arranged.
Preferably, described lower plate has main part and the first sidepiece extended from described main part two lateral buckling respectively and the second sidepiece, described magnetic steel component is located on described main part, and described magnetic gap is formed by described magnetic steel component and described first sidepiece and the second sidepiece.
Preferably, described first relief portion is located at the position near described first sidepiece on described main part, described second relief portion is located at the position near described second sidepiece on described main part, and described first relief portion and described second relief portion are all positioned at described magnetic gap.
Implement microphone device of the present utility model, there is following beneficial effect: lower plate offers relief portion in the position corresponding with voice coil loudspeaker voice coil inlet wire and outlet, when avoiding voice coil loudspeaker voice coil to move downward, lower plate is encountered in inlet wire and outlet, thus avoids inlet wire and outlet to encounter lower plate affecting sensitivity.
[accompanying drawing explanation]
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the installation diagram of voice coil loudspeaker voice coil and magnetic circuit system in microphone device of the present utility model;
Fig. 2 is the exploded view of Fig. 1 in microphone device of the present utility model;
Fig. 3 is the structural representation of lower plate in microphone device of the present utility model.
[embodiment]
As depicted in figs. 1 and 2, a kind of microphone device involving vibrations system and magnetic circuit system.Vibrational system comprises vibrating diaphragm and drives the voice coil loudspeaker voice coil 101 of diaphragm oscillations.Voice coil loudspeaker voice coil 101 is entwined by continuous print wire, therefore has inlet wire and outlet.
Magnetic circuit system comprises lower plate 105, is located at the magnetic steel component on lower plate 105 and is located at the pole piece 102 on magnetic steel component.Magnetic steel component comprises main magnet steel 103 and is separately positioned on the secondary magnet steel 104 of main magnet steel 103 both sides.As shown in Figure 3, lower plate 105 have flat main part 105a and respectively main body 105a both sides bend the first sidepiece 105b and the second sidepiece 105c of extension respectively.Magnetic steel component and define magnetic gap between the first sidepiece 105b and the second sidepiece 105c.One end of voice coil loudspeaker voice coil 101 is suspended in magnetic gap.After voice coil loudspeaker voice coil 101 is energized, the magnetic field force of generation drives voice coil loudspeaker voice coil 101 to drive diaphragm oscillations thus sounding.
The inlet wire of voice coil loudspeaker voice coil 101 and outlet are arranged on the end of voice coil loudspeaker voice coil 101 near lower plate 105 usually, and therefore, the utility model lower plate 105 has offered relief portion in the position corresponding with inlet wire and outlet.Voice coil loudspeaker voice coil 101 is when vibrating, and inlet wire and outlet would not encounter lower plate 105, avoid the impact on sensitivity.Concrete, the position near the first sidepiece 105b on main part 105a offers the first relief portion 106, and the position near the second sidepiece 105c on main part 105a offers the second relief portion 107.And the first relief portion 106 and the second relief portion 107 are all positioned at magnetic gap.Preferably, the first relief portion 106 and the second relief portion 107 are main part 105a along the groove be recessed to form away from voice coil loudspeaker voice coil 101 direction.
In the utility model, the first relief portion 106 and the second relief portion 107 are arranged in diagonal angle, and diagonal angle is arranged need not be distinguished direction when can make mounting magnetic steel assembly thus enhance productivity.
Above-described is only execution mode of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection range of the present utility model.
