Consult Fig. 2 A and Fig. 2 B, be respectively the top view of prior art bullet ripple, and the enlarged side view in A-A ' cross section among Fig. 2 A, all directions cross section of its ripple of being hit by a bullet is all identical with A-A ' cross section, is example with A-A ' cross section only.Shown in Fig. 2 A and Fig. 2 B, the material of the bullet ripple 40 of prior art is generally the cloth that contains resin pickup, is generally a similar round body, makes the cross section form the wavy shape of class to add the hot padding mode.
Yet, the bullet ripple diaphragm of prior art, whole hardness all is identical, and dried resin is hard, elasticity is relatively poor, thereby has that noise is more, low-frequency channel is difficult for manifesting, the loading resilience is not good shortcoming and not good shortcoming of tonequality.
The utility model content
The utility model provides a kind of loudspeaker bullet ripple with different hardness at the drawback of prior art.
Described loudspeaker bullet ripple with different hardness, comprise body and at least one gel coating, body is a similar round body, formed with the fabric that contains resin pickup, has a central through hole to connect voice coil loudspeaker voice coil, the cross section of this body has the wavy shape of class, gel coating is made up of a high resiliency glue material, be arranged on a presumptive area of body surface, this high resiliency glue material is the glue material, silica gel or foam etc. can make the hardness that plays ripple reduce, elasticity increases, thereby makes loudspeaker bullet ripple comprise at least two kinds of different hardness, thereby improve the shortcoming of prior art, more can be customized and adjust according to user's hobby.
By the loudspeaker bullet ripple with different hardness described in the utility model, on bullet ripple diaphragm, gel coating is set, make and play each hardness, weight, elasticity difference partly on the ripple diaphragm, thereby reduce the noise of loudspeaker, the resilience of lifting diaphragm, promote the output effect of loudspeaker low frequency, and the tonequality of loudspeaker can obviously be improved by this has the loudspeaker bullet ripple of different hardness, further can adjust according to customized demand.

Embodiment
Those skilled in the art below cooperate Figure of description that execution mode of the present utility model is done more detailed description, so that can implement after studying this specification carefully according to this.
Consult Fig. 3 A and Fig. 3 B, be respectively the top view of first embodiment of the loudspeaker bullet ripple that the utlity model has different hardness, and first embodiment that the utlity model has the loudspeaker bullet ripple of different hardness, enlarged side view with B-B ' cross section among Fig. 3 A, the all directions cross section of loudspeaker bullet ripple is all identical with B-B ' cross section, is example with B-B ' cross section only.Shown in Fig. 3 A and Fig. 3 B, the loudspeaker bullet ripple 50 that the utlity model has different hardness comprises body 60 and gel coating 71, and body 60 is a similar round body, is formed with the fabric that contains resin pickup, have a central through hole 65 to connect voice coil loudspeaker voice coil, the cross section has the wavy shape of class.Gel coating 71, formed by a high resiliency glue material, be arranged on a presumptive area on body 60 surfaces, this high resiliency glue material is glue material, silica gel or foam etc., the hardness minimizing, the elasticity that play ripple are increased, thereby make loudspeaker bullet ripple 50 ectonexines have different hardness, and improve the shortcoming of prior art, further can be according to the customized adjustment of user's hobby.
Consult Fig. 3 C to Fig. 3 E, be the end view in the B-B ' cross section of loudspeaker bullet ripple second embodiment to the four embodiment that the utlity model has different hardness.Shown in Fig. 3 C to Fig. 3 E, the loudspeaker bullet ripple 52,54,56 of second embodiment to the, four embodiment is to get according to loudspeaker bullet ripple 50 improvement of first embodiment.Shown in Fig. 3 C, the loudspeaker bullet ripple 52 of second embodiment comprises body 60 and glue figure layer 73, and gel coating 73 is arranged on the entire upper surface of body 60, and wherein the thickness of the gel coating 73 of peripheral edge portion and interior layer segment is inequality.Shown in Fig. 3 D, the loudspeaker bullet ripple 54 of the 3rd embodiment comprises body 60, first gel coating 75 and second gel coating 77, wherein first gel coating 75 is arranged at the part zone of body 60 upper surfaces, and second gel coating 77 is arranged at the zone that first gel coating 75 and body 60 upper surfaces are not provided with first gel coating 77, and first gel coating can have different thickness, hardness and coefficient of elasticity with second gel coating.Shown in Fig. 3 E, the loudspeaker bullet ripple 56 of the 4th embodiment comprises body 60, first gel coating 75 and second gel coating 77, wherein first gel coating 65 is arranged at the part zone of body 60 lower surfaces, and the second glue figure layer 77 is arranged at the entire upper surface of body 60, and first gel coating can have different thickness, weight, hardness and coefficient of elasticity with second gel coating.
First embodiment to the, four embodiment that the utlity model has the loudspeaker bullet ripple of different hardness are the examples for clear performance, the utility model is not limited thereto, and this field has prior art person and all belongs to category of the present utility model according to the combination of this embodiment, change or improvement.The various gel coatings of the utility model first embodiment to the four embodiment can be by screen painting, shielding coating, spraying, manually be coated with and mode such as attaching is arranged at body 60.
