Abstract
The utility model relates to a loudspeaker, a centering piece is mounted at the rear end of voice-coil frame of the loudspeaker. The loudspeaker consists of: a cone (1), a dust-proof cap (2), a centering piece (3), a voice coil (4), a yoke (5, 5a), a magnet (6, 6a), a ring-type magnetic conducting yoke (7), a button stem (8) and a voice-coil frame. No centering piece (3a) is available at the rear end of the voice-coil frame, the centering piece (3a) is installed between the rear end of voice-coil frame (9) and the ring-type magnetic inducting yoke (7); the ring-type magnetic inducting yoke (7) is connected to splint (10) of T iron. The utility model can overcome the radial vibration of the loudspeaker during operation by deploying the centering piece at the rear end of the voice-coil frame to support the voice-coil frame, and in addition, friction between the voice-coil and the yoke is avoided.
Description
One, technical field:
The utility model relates to loud speaker, particularly be the loud speaker that centering piece is installed in the speech coil framework rear end.
Two, background technology:
Coil-moving speaker mainly is made of centering piece, voice coil loudspeaker voice coil, speech coil framework, cone, magnetic conductive board, magnet, annular conductive magnetic yoke, dust cap, and the speech coil framework front end is near cone, and the speech coil framework rear end is away from cone; Voice coil loudspeaker voice coil is positioned at magnetic gap, and very near with the distance of conductive magnetic yoke, the space of speech coil framework rear end is narrow and small, and centering piece can't be installed, and making the speech coil framework rear end be in does not have the vacant state of support.During work, the radially vibration that voice coil loudspeaker voice coil produces can make the audio distortions that loud speaker sends, and has promptly reduced the really degree of loudspeaker reproduction sound, and when serious, voice coil loudspeaker voice coil and conductive magnetic yoke mutual friction mutually are commonly called as " rubbing circle ", can cause the loud speaker damage.For avoiding above-mentioned phenomenon the loud speaker of two-layer centering piece to occur being provided with, consult Fig. 3.This structure is still continued to use by some speaker design now, though this structure has been installed two centering pieces, but only two centering pieces are installed in the front end of speech coil framework, the rear end of speech coil framework still is in does not have holding state, as the D6 series of products in the HI-VI favour prestige board loud speaker of Zhuhai City, Guangdong Province production.
Three, summary of the invention:
The purpose of this utility model is to carry a kind of loud speaker that centering piece is installed in the speech coil framework rear end of arch at the problems referred to above, this loud speaker is provided with centering piece by the rear end at speech coil framework, in order to overcome voice coil loudspeaker voice coil radially trembles in the coil-moving speaker phenomenon, to solve voice coil loudspeaker voice coil and magnetic conductive board or the annular conductive magnetic yoke problem of mutual friction mutually.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of loud speaker that centering piece is installed in the speech coil framework rear end is made of cone, dust cap, centering piece, voice coil loudspeaker voice coil, magnetic conductive board, magnet, annular conductive magnetic yoke, speech coil framework, T iron, rear end at speech coil framework is provided with centering piece, centering piece is contained between the rear end and annular conductive magnetic yoke of speech coil framework, and annular conductive magnetic yoke is connected with the T iron splint.
The beneficial effects of the utility model are: the utility model is in the rear end of speech coil framework centering piece to be installed, centering piece is played a supporting role to speech coil framework in the rear end of speech coil framework, the phenomenon that voice coil loudspeaker voice coil radially trembles when having overcome speaker operation has effectively been avoided the friction that produces between voice coil loudspeaker voice coil and magnetic conductive board ring or the shape conductive magnetic yoke.
Four, description of drawings:
Fig. 1 is the utility model section of structure;
Fig. 2 is the section of structure of another embodiment of the utility model;
Fig. 3 is former section of structure with loud speaker.
Among the figure: 1 cone, 2 dust caps 3,3a centering piece 4 voice coil loudspeaker voice coil 4a compensation voice coil loudspeaker voice coil 5,5a magnetic conductive board 6,6a magnet 7 annular conductive magnetic yoke 8 stem stems 9 speech coil framework 10T iron splints
Five, embodiment:
Below in conjunction with embodiment and specific embodiment will the utility model is described in further detail:
Figure 1 shows that it is the utility model section of structure, as shown in the figure, the loud speaker that centering piece is installed in the speech coil framework rear end is made of cone 1, dust cap 2, centering piece 3, voice coil loudspeaker voice coil 4, magnetic conductive board 5,5a, magnet 6,6a, annular conductive magnetic yoke 7, stem stem 8, speech coil framework 9, T iron, dust cap 2 is installed in the center of cone 1, speech coil framework 9 front ends are near cone 1, and the outside of speech coil framework 9 is tied with voice coil loudspeaker voice coil 4 and sensitivity compensation voice coil loudspeaker voice coil 4a.Speech coil framework 9 front ends have centering piece 3, between rear end annular conductive magnetic yoke 7 and the speech coil framework 9 centering piece 3a are installed, and the center of centering piece 3a is connected with speech coil framework 9 rear ends, and the excircle of 3a connects annular conductive magnetic yoke 7.Magnet 6a and magnetic conductive board 5a are contained in the inside of annular conductive magnetic yoke 7, and annular conductive magnetic yoke 7 is bonding with the clamping plate 10 of T iron.The stem stem 8 of T iron transmits magnetic field by annular conductive magnetic yoke 7, makes the rear end of speech coil framework 9 form enough big space, is used to hold centering piece 3a.Centering piece 3a is contained between annular conductive magnetic yoke 7 and the speech coil framework 9, and centering piece 3a has supporting role in the rear end of speech coil framework 9 to speech coil framework 9, has effectively solved the problem that voice coil loudspeaker voice coil radially trembles.Because two centering pieces 3,3a are set the resistance of speech coil framework 9 activities to be increased in order remedying, may to cause sensitivity decline and voice coil loudspeaker voice coil 4a is set, voice coil loudspeaker voice coil 4 is two coils of the different number of turns with 4a, and voice coil loudspeaker voice coil 4 is used for the keynote circle, and 4a is used for sensitivity compensation.Voice coil loudspeaker voice coil 4 and 4a can be the coils of two same number of turns also, are all the keynote circle.Annular conductive magnetic yoke 7 among the figure is connected with the clamping plate 10 of T iron, can bonding or riveted joint.
Fig. 2 is for being another embodiment of the present utility model, shown in structure on the basis of Fig. 2, the clamping plate 10 of T iron are contained in the inside of speech coil framework 9, centering piece 3 is contained in speech coil framework 9 front ends, be connected with speech coil framework 9, centering piece 3a is contained between the rear end and stem stem stem stem 8 of speech coil framework, and annular conductive magnetic yoke 7 is connected with stem stem 8.The center of centering piece 3a connects stem stem 8, and the excircle of centering piece 3a connects speech coil framework 9.The front end of speech coil framework 9 is wound with voice coil loudspeaker voice coil 4, and the rear end of speech coil framework 9 is wound with voice coil loudspeaker voice coil 4a.Annular conductive magnetic yoke 7 and stem stem 8 riveted joints, this internal magnetization structure are because voice coil loudspeaker voice coil 4,4a and speech coil framework 9 diameters are bigger, and cone 1 is stressed even.
Related voice coil loudspeaker voice coil 4,4a in the scheme, speech coil framework 9 provides concrete specification, parameter customized to producer, and other loudspeaker accessory is commercially available finished product.
