Description
Technical field
The utility model is specifically related to a kind of In-Ear receiver.
Background technology
Receiver is a kind of electroacoustic transducer in speech communication, the signal of telecommunication being converted to corresponding acoustical signal.Voice coil loudspeaker voice coil is arranged in the gap of outside magnet ring and the formation of inner T-shaped iron by the receiver of prior art, and must ensure that voice coil loudspeaker voice coil is placed in the central authorities of magnetic gap, can not collide with magnet or T-shaped iron, so restricted to the size of voice coil loudspeaker voice coil during vibration.But the conductor length of voice coil loudspeaker voice coil is depended on again in the sensitivity of receiver, require that receiver internal capacity must reach certain requirement conversely.Which adds the design difficulty of receiver, the miniaturization of receiver is restricted.
Summary of the invention
The utility model object is the defect for above-mentioned prior art, provides a kind of In-Ear receiver, overcomes with prior art the defect that receiver design difficulty is large, the miniaturization of receiver is restricted.
To achieve these goals, the technical solution of the utility model is:
A kind of In-Ear receiver, comprise stainless steel stent, voice coil loudspeaker voice coil, cylindrical magnetic iron, vibrating diaphragm, PC plate and sheath, described cylindrical magnetic iron is arranged on the cavity center of stainless steel stent inside; The interior cavity diameters of described stainless steel stent is 16-20mm; Described cylindrical magnetic iron diameter is 5-10mm; Described voice coil loudspeaker voice coil is that coiling coiling forms, and voice coil loudspeaker voice coil is fixed on below vibrating diaphragm, and vibrating diaphragm is arranged on above cylindrical magnetic iron; Described stainless steel stent top is provided with ladder, and described sheath lower end is bonded in above the ladder of stainless steel stent; Described PC plate is fixed on the stainless steel stent inside sheath, and is connected with the coiling of voice coil loudspeaker voice coil; Damping fin is provided with below internal stent.
As the improvement to technique scheme, be provided with washer sheet below cylindrical magnetic iron, washer sheet is connected with stainless steel stent, is provided with magnetic conductor above cylindrical magnetic iron.
As the improvement to technique scheme, sheath upper end is circular shape, and sheath center has the phonate hole coaxial with cylindrical magnetic iron.
Useful point of the present utility model is, magnet ring of the prior art is replaced to cylindrical magnetic iron and is arranged on the cavity center of stainless steel stent, stainless steel stent serves the effect of magnetic conduction simultaneously, eliminate T-shaped iron of the prior art, voice coil loudspeaker voice coil is arranged in the gap that cylindrical magnetic iron and stainless steel stent formed, under the condition of not losing the sensitivity of receiver, the miniaturization of receiver can be accomplished further; Meanwhile, cylindrical magnetic iron is arranged on stainless steel stent inside by this programme, can greatly reduce magnetic leakage, improves the sounding effect of receiver.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structural representation.
Reference numeral: 1-stainless steel stent; 2-sheath; 3-cylindrical magnetic iron; 4-voice coil loudspeaker voice coil; 5-vibrating diaphragm; 6-washer sheet; 7-phonate hole; 8-damping fin; 9-magnetic conductor; 10-PC plate.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model; those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
The In-Ear receiver of one as shown in Figure 1, comprise stainless steel stent 1, voice coil loudspeaker voice coil 4, cylindrical magnetic iron 3, vibrating diaphragm 5, PC plate 10 and sheath 2, cylindrical magnetic iron 3 is arranged on the cavity center of stainless steel stent 1 inside; The interior cavity diameters of stainless steel stent 1 is 16-20mm; Cylindrical magnetic iron 3 diameter is 5-10mm; Described voice coil loudspeaker voice coil 4 forms for coiling coiling, and voice coil loudspeaker voice coil 4 is fixed on below vibrating diaphragm 5, and vibrating diaphragm 5 is arranged on above cylindrical magnetic iron 3; Stainless steel stent 1 top is provided with ladder, and sheath 2 lower end is bonded in above the ladder of stainless steel stent 1; PC plate 10 is fixed on the stainless steel stent 1 inside sheath 2, and is connected with the coiling of voice coil loudspeaker voice coil 4; Stainless steel stent 1 lower inside is provided with damping fin 8, be provided with washer sheet 6 below cylindrical magnetic iron 3, washer sheet 6 is connected with stainless steel stent 1, is provided with magnetic conductor 9 above cylindrical magnetic iron 3, sheath 2 upper end is circular shape, and sheath 2 center has the phonate hole 7 coaxial with cylindrical magnetic iron 3.
Cylindrical magnetic iron 3 is arranged on the cavity center of stainless steel stent 1 by this programme, stainless steel stent 1 serves the effect of magnetic conduction simultaneously, voice coil loudspeaker voice coil 4 is arranged in the gap that cylindrical magnetic iron 3 and stainless steel stent 1 formed, and the receiver in this programme can further minification on the basis of existing technology; Meanwhile, this programme can greatly reduce magnetic leakage, and the sounding effect of receiver is better.
