Summary of the invention
The objective of the invention is to propose a kind of moving iron unit of structure improved earphone that has, it has adopted balanced armature and the magnetic Circuit Design optimized, can effectively improve the resolution and the conversion efficiency of earphone, reduces harmonic distortion, thereby has overcome deficiency of the prior art.
For realizing the foregoing invention purpose, the present invention has adopted following technical scheme:
A kind of have a moving iron unit of structure improved earphone; Comprise the balanced armature, vibrating diaphragm and the magnet mechanism that are arranged in the shielding case; Said balanced armature is a horseshoe clamp weighing apparatus armature, and its both sides are at least one coil of coiling respectively, and said coil all connects with series system; The corresponding setting of said magnet mechanism with the balanced armature peristome, and said balanced armature and vibrating diaphragm are in transmission connection.
Further, the both sides of said balanced armature are in transmission connection through first, second conductive bar and first, second vibrating diaphragm respectively.
Preferably, said first, second vibrating diaphragm is symmetricly set in the balanced armature both sides, and the upper/lower terminal portion of these two vibrating diaphragms is fixedly connected with the shielding case inwall respectively at least.
Preferably, said shielding case comprises the metal shell with peristome.
Preferably, the regional area of said at least magnet mechanism is inserted in the peristome of said balanced armature.
Preferably, said magnet mechanism first, second permanent magnet of comprising I-shaped iron core and being symmetricly set in the iron core both sides.
As a kind of available execution mode, said balanced armature both sides are symmetrical coiling one coil respectively, and these two coils connect with series system.
Compared with prior art, the invention has the advantages that:
(1) adopted twin coil to drive same " U " shape balanced armature, and can through number of turns and the impedance ratio that changes these two coils respectively, realize that segmentation drives, separately-driven effect according to the requirement of concrete use;
(2) adopted unique vibrating diaphragm Drive Structure design; Reciprocation by magnet, coil and balanced armature can drive two vibrating diaphragms sounding simultaneously simultaneously; And two vibrating diaphragms can have independently Machine Design, compare traditional a slice vibrating diaphragm; Promote the conversion efficiency of product, enriched the frequency response curve of moving iron unit;
(3) adopted two magnet to be combined in the structural design on " worker " font iron core, effectively optimized magnetic circuit, improved its utilization ratio, and structure is more compact firmly.
Description of drawings
Fig. 1 is the cross-sectional view of the motor-driven iron of the present invention's one preferred embodiment middle ear unit;
Each Reference numeral and indicated assembly thereof are respectively among the figure: 1-balanced armature, 2, the 3-coil, 4-shielding case, 5,6-magnet, 7-iron core, 8, the 9-vibrating diaphragm, 10, the 11-conductive bar.
Embodiment
Below in conjunction with an accompanying drawing and a preferred embodiment technical scheme of the present invention is further described.
Consult Fig. 1, this preferred embodiment relates to the moving iron unit of a kind of earphone through improvement design, and it comprises the balanced armature 1 that is arranged in the irony shielding case 4; Two vibrating diaphragms 8,9 and magnet mechanism; Said balanced armature 1 is horseshoe clamp weighing apparatus armature, and its both sides are coiling one coil 2,3 respectively, and these two coils connect with series system; Said magnet mechanism and the corresponding setting of balanced armature 1 peristome, and said balanced armature 1 is in transmission connection with vibrating diaphragm.
Particularly, said vibrating diaphragm 8,9 is symmetricly set in balanced armature 1 both sides, and the upper/lower terminal portion of these two vibrating diaphragms is fixedly connected with shielding case 4 inwalls respectively, and simultaneously, these two vibrating diaphragms are in transmission connection through the both sides of conductive bar 10,11 and balanced armature 1 respectively.
As preferred scheme, the regional area of aforementioned magnet mechanism is inserted in the peristome of said balanced armature 1.
More preferred, aforementioned magnet mechanism comprises I-shaped iron core 7 and symmetry absorption or is fixed in the magnet 5,6 of iron core 7 both sides.
When this moving iron cell operation; The signal of telecommunication can be through the coil 2,3 that connects with series system; According to electromagnetic induction effect, balanced armature 1 can be magnetized in the magnetic field that alternating current in the coil 2,3 produces, and balanced armature 1 can push away, draw effect with the magnet 5,6 that is fixed on the iron core 7 according to the same sex is repelled each other, there is a natural attraction between the sexes principle; Because of vibrating diaphragm 8,9 is in transmission connection by conductive bar 10,11 and balanced armature 1; Drive and be extruded or when stretching, can drive conductive bar 10,11 motions when balanced armature 1 receives coil 2,3, conductive bar 10,11 can drive vibrating diaphragm 8,9 vibrations again; And spread out of in the opening of vibration meeting blow air by screen iron cover 4 of this vibrating diaphragm 8,9, thereby sound.
