Abstract
The utility model discloses a loudspeaker cone which comprises a vibrating body and a cone rim connected with the vibrating body, wherein the cross section of the main body of the cone rim is arc-shaped, and the cone rim consists of a fabric base and an adhesive layer arranged on the fabric base. The fabric base is made of non-woven fabrics or mixture of non-woven fabrics and long fiber paper, and the resin as adhesive layer is stuck to the fabric base. The cone rim is made of non-woven fabrics or mixture of non-woven fabrics and long fiber paper and the resin as adhesive layer is stuck to the fabric base, so that the loudspeaker cone has low manufacturing cost, bears the stress uniformly at 360-degree full angle, reduces the distortion of tone quality, ensures good sound quality, and is beneficial for environment.
Description
Technical field
The utility model relates to the loudspeaker techniques field, relates in particular to the improvement of the basin limit structure of shaking of speaker cones.
Background technology
Speaker cones is mainly used in and promotes air to send the sound of different frequency, and the improvement of existing speaker cones changes in material therefor and shape moulding thereof mostly obtains better acoustical quality.
Speaker cones mainly is made of with the basin limit that shakes that is connected the vibrating body periphery the vibrating body at middle part.The effect of vibrating body is in admission of air vibration and transfer of vibration, the fixedly connected vibrating body of acting on of basin limit that shakes, and by the basin limit that shakes of arch the Vibrant buffer of vibrating body, basin integral body can be transmitted sound vibration signal to guarantee to shake.
The material that the existing basin vibrating body that shakes adopts roughly has following several: paper pulp, light metal paper tinsel, fibrous braid and plastic foam material etc., and with regard to the loudspeaker vibration body structure that material therefor is formed, have coated mica on the vibrating body or on the vibration base material in conjunction with the double-layer structure form of layer of metal cloth, as the disclosed structure of Chinese CN200420074057.8 patent " loudspeaker drum paper structure ", three-decker forms such as adopting paper fiber, hardware cloth and mica are arranged also.And for shaking the basin limit, in order to satisfy good toughness and lightweight requirement, the basin limit that shakes at present mainly is made by spinning, rubber, sponge, the TPU of individual layer, but the basin limit that shakes of existing this class formation, all directions discontinuity can influence the basin tonequality of shaking.
The utility model content
Problem to be solved in the utility model provides that a kind of tonequality is good, distortion circlet guarantor type speaker cones.
The utility model is achieved through the following technical solutions:
Design a kind of speaker cones, involving vibrations body and the basin limit that shakes that links to each other with vibrating body, the described basin limit main body section that shakes is arch, and the described basin limit that shakes is made of cloth matter base material and the adhesive-layer that is arranged on the cloth matter base material.
As the improvement of such scheme, cloth matter base material is made by nonwoven fabrics, or is mixed and made into by nonwoven fabrics and long fibered paper, is bonded with resin as adhesive-layer on this cloth matter base material.
The utility model compared with prior art has following remarkable result:
The basin that shakes provided by the utility model, the basin limit base material that shakes are made by nonwoven fabrics or are mixed and made into by nonwoven fabrics and with long fibered paper, are bonded with resin as adhesive-layer on its cloth matter base material.Basin 360 degree that shake of this structure are comprehensive stressed even, can reduce quality distortion, and acoustical quality is good, and environmental protection, low cost of manufacture.And the existing basin limit that shakes of adopting similar spinning cloth to make because spinning cloth forms through, weft yarn braiding, causes the basin limit each side of shaking stressed inequality easily, can influence the basin acoustical quality that shakes.
Description of drawings
Fig. 1 is a plan structure schematic diagram of the present utility model;
Fig. 2 is the partial schematic sectional view of Fig. 1.
Fig. 3 is the enlarged diagram of A portion among Fig. 2.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Referring to Fig. 1,2, a kind of speaker cones, the basin main body of shaking is made up of with the basin limit 2 that shakes that links to each other with vibrating body vibrating body 1, plays better cushioning effect in order better to make the basin limit that shakes, and the basin limit main body section that shakes is for being arch.
The vibrating body of the tapered body in the present embodiment adopts the paper fiber to make and forms, the basin limit that shakes that connects on its outer periphery is made by double-layer structure, its substrate layer is a cloth matter base material 21, it can be nonwoven fabrics, also can be the mixture of nonwoven fabrics and fibrous paper that wherein fibrous paper is preferably selected long fibered paper for use.Select for use long fibered paper or nonwoven fabrics as base material, can be stressed evenly feasible basin limit 360 full angles that shake, the also feasible basin transmission effect of shaking is better, can reduce quality distortion, and acoustical quality is good.
Basin limit hardness is strong, good integrity in order to make made shaking, and the cloth matter base material 21 on the basin limit that shakes also is provided with adhesive-layer 22, and adhesive-layer can be selected the resin material with viscosity environmental protection for use.The not only low-cost but also environmental protection of the basin that shakes with this basin limit that shakes.
The basin that shakes provided by the utility model, the basin limit base material that shakes are made by nonwoven fabrics or are mixed and made into by nonwoven fabrics and with long fibered paper, are bonded with resin as adhesive-layer on its cloth matter base material.The basin low cost of manufacture of shaking of this structure, 360 full angles are stressed evenly can to reduce quality distortion, and acoustical quality is good, and environmental protection.
The foregoing description is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement also should fall within the protection range of the present utility model.
Claims (3)
1, a kind of speaker cones, involving vibrations body (1) and the basin limit (2) that shakes that links to each other with vibrating body, the described basin limit main body section that shakes is arch, it is characterized in that: the described basin limit that shakes is made of cloth matter base material (21) and the adhesive-layer (22) that is arranged on the cloth matter base material.
