Embodiment
For the ease of more fully understanding the utility model, the utility model is carried out below in conjunction with related embodiment accompanying drawingIt is further explained.Give embodiment of the present utility model in accompanying drawing, but the utility model be not limited in it is above-mentioned preferredEmbodiment.Conversely, there is provided the purpose of these embodiments be in order that open face of the present utility model more fully.
Fig. 1 to Fig. 2 is referred to, the utility model first embodiment provides a kind of speaker vibration system 100, including middle patch10th, rectangle knot is used with 10 vibrating diaphragms 20 being connected of the middle patch and the voice coil loudspeaker voice coil 30 being connected with the vibrating diaphragm 20, the middle patch 10Structure, the vibrating diaphragm 20 is using cone vibrating diaphragm, plastics vibrating diaphragm, metal vibration diaphragm or synthetic fibers vibrating diaphragm etc., and the vibrating diaphragm 20 is by adoptingTransfer voice is carried out with the mode of vibration.
Referring to Fig. 4, being the structural representation of voice coil loudspeaker voice coil in Fig. 2 30, the voice coil loudspeaker voice coil 30 includes body 31 and located at describedThe lead 32 of the both sides of body 31, the body 31 use cuboid hollow-core construction, and the lead 32 is made of metal material, describedLead 32 includes kink 33, the connecting portion 34 being connected with the kink 33 and located at the pad end of the end of connecting portion 3435, the kink 33 is connected with the side wall of the body 31, by the design of the kink 33, improves the lead 32The stability of structure between the body 31, and then improve the stability of the structure of voice coil loudspeaker voice coil 30.
Referring to Fig. 3, being the structural representation of vibrating diaphragm in Fig. 1 20, depression forms a depression downwards at the middle part of vibrating diaphragm 20Platform 22, the depression platform 22 use rectangle structure, and the middle patch 10 is in the depression platform 22, and the middle patch 10 and instituteState and be fixed using glue between depression platform 22, depression platform 22 side is provided with ring 23, and the ring 23 is for neutralizingThe lead 32 waves caused stiffness asymmetry, so that the speaker vibration system 100 balanced can vibrate when working, reductionDue to non-linear distortion caused by the lead 32, the performance of the speaker vibration system 100 is improved.
The ring 23 includes the first lug boss 24, the second lug boss 25 and the 3rd lug boss 26 sequentially connected, describedFirst lug boss 24 and the 3rd lug boss 26 are respectively arranged on two sides that the depression platform 22 opposes, the pad end 35Towards first lug boss 24, the kink 33 is towards the 3rd lug boss 26, the width of first lug boss 24More than the width of the 3rd lug boss 26, because the pad end 35 is fixed on by the way of being welded and fixed in the present embodimentOn pad so that the end amplitude of the lead 32 is smaller, the amplitude of the kink 33 when 32 rocking vibration of leadMore than the amplitude at the pad end 35, and then it is more than by the width of first lug boss 24 width of the 3rd lug boss 26Degree design so that the rigidity of first lug boss 24 is less than the rigidity of the 3rd lug boss 26, by by the big institute of amplitudeState kink 33 and rigid big the 3rd lug boss 26 is placed on the same side, the small pad end 35 of amplitude and rigidity are smallFirst lug boss 24 is placed on the same side, in a manner of making using big rigid large amplitude of disinthibiting so that the loudspeaker shakesDynamic system 100 keeps vibration balancing, it is therefore prevented that the asymmetric phenomenon of stiffness occurs in the speaker vibration system 100, reducesNon-linear distortion caused by vibrating difference due to the lead 32, improve the performance of the speaker vibration system 100.
The kink 33 includes fitting section 331 and the changeover portion 332 being connected with the fitting section 331, the fitting section331 use the column construction of strip, and the fitting section 331 is fitted in the side of the body 31, and the changeover portion 332 is using halfCircular configuration, described one end of changeover portion 332 are connected with the fitting section 331, and the other end is connected with the connecting portion 34, passes through instituteThe design for stating changeover portion 332 make it that transition connects between the fitting section 331 and the body 31, and then reduces due to describedBody 31 vibrates the vibration difference of the caused lead 32, it is therefore prevented that it is not right that stiffness occurs in the speaker vibration system 100The phenomenon of title.
The connecting portion 34 is parallel with the side of the body 31, and the distance between two described connecting portions 34 are more than instituteThe width of depression platform 22 is stated, and then when the voice coil loudspeaker voice coil 30 is fitted in depression 22 back side of platform, the connecting portion 34 extendsThe rear surface regions of the depression platform 22, the length of first lug boss 24 are equal to the length of the 3rd lug boss 26 and are less thanThe length of second lug boss 25.
The upper surface of the body 31 is fitted in the back side of the depression platform 22, and the height of projection of the ring 23 is more than instituteThe thickness of middle patch 10 is stated, the thickness of the body 31 is more than the height of projection of the ring 23, the back side drift angle of the middle patch 10Provided with a glue groove, the fitting that the middle patch 10 and the vibrating diaphragm 20 are facilitated by the design of described glue groove operates, to improveThe packaging efficiency of the speaker vibration system 100.
The present embodiment improves structure between the vibrating diaphragm 20 and the middle patch 10 by the design of the depression platform 22Stability, the width design of the 3rd lug boss 26 is more than by the width of first lug boss 24 so that described firstThe rigidity of lug boss 24 is less than the rigidity of the 3rd lug boss 26, by the way that the big kink 33 of amplitude and rigidity is big3rd lug boss 26 is placed on the same side, and the small pad end 35 of amplitude and rigid small first lug boss 24 are placed onThe same side, in a manner of making using big rigid large amplitude of disinthibiting so that the speaker vibration system 100 keeps vibration flatWeighing apparatus, it is therefore prevented that the asymmetric phenomenon of stiffness occurs in the speaker vibration system 100, reduces because the lead 32 vibration is ledThe non-linear distortion of cause, the sounding performance of the speaker vibration system 100 is improved, and pass through the design of the kink 33So that transition connects between the lead 32 and the body 31, and then reduce described caused by the body 31 vibratesThe vibration difference of lead 32, it is therefore prevented that the asymmetric phenomenon of stiffness occurs in the speaker vibration system 100, further increasesThe performance of the speaker vibration system 100.
Referring to Fig. 5, the speaker vibration system 100a provided for the utility model second embodiment structural representation,The structure of the second embodiment and first embodiment is more or less the same, and its difference is, the drift angle of vibrating diaphragm 20a described in the present embodimentPositioning through hole 40 is provided with, the positioning through hole 40 uses circular configuration, and the positioning through hole 40 is used to facilitate the vibrating diaphragm 20aPositioning assembling, to improve the packaging efficiency of the speaker vibration system 100a.
This implementation is by the design of the positioning through hole 40, when carrying out the assembling of the speaker vibration system 100a,By fixation of the external stability post to the positioning through hole 40, so as to prevent the movement of vibrating diaphragm 20a described in assembling process, enterAnd improve the packaging efficiency of the speaker vibration system 100a.
