Description
Technical field
The present invention relates to ear phone technology field, more particularly to a kind of rectangular moving-coil loudspeaker.
Background technology
Traditional moving-coil unit loudspeaker, direction of usually pronouncing is, moving-coil loudspeaker, due to entirely sending out identical with the axial direction of diaphragm
Line point is rounded, and pronunciation area is larger, therefore it is usually with positive round, and the pattern of flattening appears in earphone products
Face, simultaneously because circular diaphragm can have sufficiently large area and relatively large Oscillation Amplitude, therefore the performance one of its low frequency
It is straight all more satisfactory, but volume compares larger, cannot be satisfied the market rigors smaller and smaller to In-Ear Headphones volume.
In contrast, move iron loudspeaker has apparent advantage in volume, and dynamic iron loudspeaker are driven by the vibrations of armature
The iron plate at the top of loudspeaker cavity is fixed on to make a sound, and the sound mouth that goes out that sound need to pass through in loudspeaker side is spread out of.Such as Fig. 2
It is shown, since dynamic iron loudspeaker are effectively to reduce the area at pronunciation end, therefore earphone can be made smaller by side sounding.No
It crosses due to dynamic iron loudspeaker, his frequency response is narrow, and low frequency behavior is poor, although overall body volume is effectively reduced, but
The sound performance of full frequency band cannot be individually undertaken, relatively better sound reproduction can just be accomplished by needing multiple units to cooperate jointly.
After being superimposed by multiple-unit, its volume can also become larger, and earphone can not also be allowed to accomplish the requirement of miniaturization.
Therefore, above two loudspeaker cannot all accomplish the good and small idealization requirement of low frequency behavior.
Invention content
Based on the deficiencies of the prior art, the purpose of the present invention is to provide a kind of rectangular moving-coil loudspeaker, moving-coil is effectively reduced
The volume of loudspeaker improves sound quality.
To achieve the above object, the technical scheme is that：
A kind of rectangular moving-coil loudspeaker, including shell, magnet, T iron, washer, diaphragm, voice coil, protecting cover and pcb board, feature
It is：The shell uses the square casing of upper end opening, and side is provided with sound regulating hole in the shell, and the other side is equipped with one and holds
Receive space, the diaphragm is oval racetrack, and the T iron is inverted in the bottom of the accommodation space, setting in the middle part of the magnet
There are via, the magnet to be sheathed on the lower part of the T columns of the T iron by the via in the middle part of itself, the voice coil is set in described
The top of the T columns of T iron, the membrane covered is on the voice coil, and washer is set on the T columns of the T iron on magnet top, institute
It states protecting cover to fasten on the housing, forms shell entirety, shell entirety is additionally provided with sound mouth on side.
Further, the pcb board is arranged on the opposite case panel of sound mouth.
Further, the shell is rectangle shell.
Further, the protecting cover is oval racetrack.
Further, the magnet uses annular magnet.
Beneficial effects of the present invention are：It is small, frequency response is wide, highly reliable and simple in structure, cheap.
Description of the drawings
Fig. 1 is the cross-sectional view of the specific embodiment of the invention；
Fig. 2 is the decomposition texture schematic diagram of the specific embodiment of the invention.
Specific implementation mode
The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to schematic diagram clear, complete
Ground describes, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is the one of the present invention
Section Example, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not paying creativeness
The other embodiment obtained under the premise of labour, belongs to the scope of protection of the invention.
As depicted in figs. 1 and 2, a kind of rectangular moving-coil loudspeaker, including shell 1, magnet 2, washer 9, T iron 3, diaphragm 4, voice coil
5, protecting cover 6 and pcb board 7, the shell 1 use the square casing of upper end opening, 1 side of the shell to be provided with sound regulating hole 11,
The other side is set there are one accommodation space, and the diaphragm 4 is oval racetrack, and the T iron 3 is inverted in the bottom of the accommodation space
Portion, 2 middle part of the magnet are provided with via, and the magnet 2 is sheathed on by the via in the middle part of itself under the T columns of the T iron 3
The magnet in portion, the present embodiment uses annular magnet, the voice coil 5 to be set in the top of the T columns of the T iron 3, and the diaphragm 4 covers
It covers on the sound regulating hole 11 and the voice coil 5, washer 9 is set on the T columns on the top of annular magnet, and washer 9 is located at
Between magnet and diaphragm, play magnetic conduction, the protecting cover 6 is fastened on the shell 1, forms shell entirety, shell unitary side
Sound mouth 8 is additionally provided on side.The pcb board 7 is arranged on the opposite case panel of sound mouth 8.The shell 1 is rectangle
Shell.The protecting cover 6 is oval racetrack.
The shell of the present embodiment compares previous loudspeaker, effectively reduces volume, still, frequency response is wider, and reliability is stronger, valence
Lattice are cheap.Meanwhile crash resistance is significantly better than complicated dynamic iron loudspeaker, the cross-sectional area of shell is less than 7mm, and diaphragm
Diameter is more than 10mm, receives the pronunciation component of bigger in sufficiently small space content, effectively improves sound expressive force and details weight
It is existing.
Since the frequency response of this loudspeaker is wider, the expressive ability that monomer curve can be from 20Hz to 5kHz, in this way
On the basis of, it is only necessary to a upper small dynamic iron unit of arranging in pairs or groups on the basis of him, so that it may effectively to promote the extension of its high frequency
Ability.Especially on customization earphone, it can be closed in small unit group and make outstanding sound performance.
It should be noted that described above is presently preferred embodiments of the present invention, the invention is not limited in above-mentioned
Embodiment should all belong to the scope of protection of the present invention as long as it reaches the technique effect of the present invention with identical means.
