The design feature of moving-iron type earbud headphone determines it and has better performance in medium-high frequency section, and then moving-coil type earbud headphone is more weak relatively in low-frequency range performance.
Even but moving-coil type earbud headphone, also because the loudspeaker bore of loud speaker in earplug is little, voice coil loudspeaker voice coil bore is little, voice coil loudspeaker voice coil wire diameter is thin and diaphragm is gently thin, cause its sound in low-frequency range to show still not ideal enough.Consumer cannot strong low frequency atmosphere and profound low frequency dive in profound lesson to musical works, causes the music of consumer to listen to impression and declines to a great extent.
How to design a kind of consumer of allowing and experience strong low-frequency vibration and powerful low frequency behavior, thus the appeal can realizing musical works fast becomes the problem needing solution badly.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of low frequency vibrator that outwards can give off the low frequency sound signals with preferred amount of sense and texture.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of low frequency vibrator, comprise frame, voice coil loudspeaker voice coil, magnetic circuit assembly and vibrating diaphragm, described magnetic circuit assembly is by U iron, be stacked in the magnet in described U iron and washer sheet formation successively, the magnetic gap of annular is formed between the madial wall of described U iron and magnet and washer sheet, the bottom of described voice coil loudspeaker voice coil is glued to the bottom surface center of described frame, described vibrating diaphragm is plane diaphragm, described plane diaphragm is connected to the top open part of described frame, the bottom of described U iron is bonded in described plane diaphragm for the side surface middle part towards described frame inside, described magnetic circuit assembly back-off is suspended at above described voice coil loudspeaker voice coil, the end of described voice coil loudspeaker voice coil is inserted in described magnetic gap.
Further, bore for the ease of voice coil loudspeaker voice coil strengthens, the increasing of loudspeaker wire diameter, described frame is that the lower cover being located at described annular brace framework under shed face place by the annular brace framework and lid with upper and lower opening face is formed, the middle part of described lower cover offers bleeder port, and the edge conjunction of described plane diaphragm is on the sidewall at described annular brace framework upper shed face place.
Further, described plane diaphragm comprises in plane central part and is connected to the ring portion of described central part edge, and the edge conjunction in described ring portion is on the sidewall at described annular brace framework upper shed face place.
Further, described lower cover is provided with the circular groove, the diameter of circular groove and the diameter compatible of described voice coil loudspeaker voice coil that glued joint for described voice coil loudspeaker voice coil in the middle part of the medial surface in annular brace framework direction.
Further, the bore of described voice coil loudspeaker voice coil is 8mm-20mm.
Further, the wire diameter on described voice coil loudspeaker voice coil is 0.06mm-0.16mm.
Further, described lower cover is made up of carbon fine sheet, copper sheet or sheet.
The beneficial effects of the utility model are:
The voice coil loudspeaker voice coil of the low frequency vibrator in the utility model is fixed and magnetic circuit assembly is fixed on plane diaphragm.Operationally, when voice signal access after, under the promotion of magnetic force magnetic circuit assembly can relatively voice coil loudspeaker voice coil motion, magnetic circuit assembly take plane diaphragm vibrate.Relative conventional loudspeakers, the utility model is increased in diaphragm of loudspeaker quality total when vibration sounding by utilizing magnetic circuit assembly, to promote amount sense and the texture of low frequency sound signals, the sensation of the person of enhancing listening when music low frequency signal, makes auditor experience more low-frequency effect.
Low frequency vibrator in the utility model can coordinate conventional speakers to use in earplug, can adopt the mode of frequency division, targetedly in the low-frequency range work of regulation.
In addition, can also in conjunction with the changes of aspect such as the material to ring, hardness, thickness and shape and the quality matches of magnetic circuit vibrates system to reach the LF-response wanted.
