Abstract
The utility model discloses the armature that a kind of magnetic is concentrated, comprise armature body, described armature body involving vibrations transducing portion, this vibration transducing portion comprises free end and stiff end, described free end is being arranged on iron core inner ring and between two magnet be oppositely arranged, the sidewall thickness of described free end is less than the sidewall thickness of stiff end.The utility model design is ingenious, easily manufactured, the concentrated object of magnetic is reached by the sidewall thickness of free end in thinning vibration transducing portion, and then improve the amplitude of the up-down vibration vibrating free end in transducing portion, make to show that audio fruit is good, simultaneously due to the sidewall of free end thinning under the effect of magnetic force Oscillation Amplitude larger, go out sound better effects if.
Description
Technical field
The utility model relates to a kind of armature, more particularly, relates to the armature that a kind of magnetic is concentrated.
Background technology
Dynamic iron earphone is as mid-to high-end product in the market, in dynamic iron earphone there is critical component for dynamic iron unit in it, it is for moving-coil earphone, frequency response curve is more stable, sensitivity is higher, pleasant dark, the advantage such as resistance is little, focused on gradually the music-lover of tonequality accept pay attention to institute's fan.The primary structure of existing dynamic iron unit comprises: the compositions such as shielding case, syndeton, magnetic drive assembly and vibrating diaphragm, magnetic drive assembly comprises the compositions such as iron core, magnet, armature and coil.The operation principle of existing dynamic iron unit is: when dynamic iron unit is started working, by coil generating electromagnetic inductive effect, and alternating magnetic field of inducting, alternating magnetic field can magnetize the armature being placed in coil, armature can according to homopolar-repulsion, the principle that heteropole is attracting and permanent magnet produce push-and-pull action power, the free end in one end of syndeton and the vibration transducing portion of armature connects, the other end and vibrating diaphragm bond and connect, the conduct vibrations of armature is driven diaphragm oscillations to vibrating diaphragm by syndeton, vibrating diaphragm drives its ambient air to vibrate, and then audio signal is exported.Therefore according to above-mentioned operation principle, the tone height of the sound that dynamic iron unit exports depends on vibration of membrane of shaking, and then and alternating magnetic field, the density degree that the magnetic induction line that permanent magnet and alternating magnetic field produce acts on the free end in vibration transducing portion is relevant, therefore when not changing intensity and the permanent magnet structure of alternating magnetic field, in order to improve the tone of the sound that dynamic iron unit exports, we can concentrate magnetic to concentrate when considering that the magnetic induction line that the sidewall thickness by changing free end in vibration transducing portion makes alternating magnetic field produce acts on the free end in vibration transducing portion, and then reach above-mentioned object.
Summary of the invention
1. the utility model technical problem that will solve
The purpose of this utility model is to overcome above-mentioned deficiency, provide the armature that a kind of magnetic is concentrated, adopt the technical solution of the utility model, structure is simple, designs ingenious, easily manufactured, reach the concentrated object of magnetic by the sidewall thickness of free end in thinning vibration transducing portion, and then improve the amplitude of the up-down vibration vibrating free end in transducing portion, make to show that audio fruit is good, simultaneously due to the sidewall of free end thinning under the effect of magnetic force Oscillation Amplitude larger, go out sound better effects if.
2. technical scheme
For achieving the above object, the technical scheme that the utility model provides is:
The armature that a kind of magnetic of the present utility model is concentrated, comprise armature body, described armature body involving vibrations transducing portion, this vibration transducing portion comprises free end and stiff end, described free end is being arranged on iron core inner ring and between two magnet be oppositely arranged, the sidewall thickness of described free end is less than the sidewall thickness of stiff end.
Further, the sidewall sections shape of described free end is rectangle.
Further, the sidewall sections shape of described free end is isosceles trapezoid.
3. beneficial effect
The technical scheme adopting the utility model to provide, compared with existing known technology, has following beneficial effect:
The armature that a kind of magnetic of the present utility model is concentrated, the sidewall thickness of its free end is less than the sidewall thickness of stiff end, the sidewall sections shape of free end is the sidewall sections shape of rectangle or free end is isosceles ladders, structure is simple, design ingenious, easily manufactured, the concentrated object of magnetic is reached by the sidewall thickness of free end in thinning vibration transducing portion, and then the amplitude of the up-down vibration of the free end in raising vibration transducing portion, make to show that audio fruit is good, simultaneously due to the sidewall of free end thinning under the effect of magnetic force Oscillation Amplitude larger, go out sound better effects if.
