Abstract

The utility model relates to a paper-honeycomb-paper sandwich multiple layer type sound basin structure, mainly comprising a first layer paper basin, a second layer paper basin, and a middle interlayer which is a Nomex or aluminum honeycomb structure. The Nomex or aluminum honeycomb structure of the middle interlayer and the paper basins are glued together, forming the paper-honeycomb-paper sandwich multiple layer type sound basin structure by the resin adhering coated and applied on the interface of the first layer paper basin, the second layer paper basin, and the Nomex or aluminum honeycomb structure of the middle interlayer. The application of the material composition and the structure improvement of the multiple layer type loudspeaker can make the sound basin combined have the advantages of light quality and good loss property of the paper internal, the rigidity of the oscillation plate of the sound basin combined also can be largely increased, and the efficiency of the sound basin combined is improved.

Description

Paper-honeycomb-paper sandwich multi-layer sound basin structure

Technical field

The utility model is to improve on the relevant paper cone for loudspeaker structure, refers to that especially a kind of upper strata and lower floor are the Paper bowl cone, and the intermediate layer is the paper-honeycomb-paper sandwich multi-layer sound basin structure of the high rigidity honeycomb structure of tool.

Background technology

Press known traditional loudspeaker cone, the mostly cone shape of making by paper pulp or high molecule plastic.Can hear 20 hertz to the audiorange of 20 KHz at people's ear, in the range scope of low frequency, the sound basin of cone shape, the mode of rigid body is vibrated relatively, therefore has lower distortion.But the inertia strength that is produced when high frequency is bigger, makes that general sonic vibrator sound basin can't be in when vibration, rigidity that still is consistent thereby the distortion when causing sound reproduction.

Be that one of design effort direction with many sound basins is all in the rigidity that increases the sound basin and alleviate quality.As material Consideration aspect, be high less, the suitable internally-damped and lighter overall weight of modulus of direct elasticity, density from design.

In having the material of these characteristics, as boron nitride or graphite etc.The shortcoming that price is relatively costly makes to become unactual in the manufacture process of shiploads of merchandiseization.And known used sound cone material has moulding after impregnation such as glass fibre, ballistic fiber (Kevlar) and cloth, but the cost that this material spent is higher, quality is heavier, thereby efficient is relatively poor relatively.

In view of this, this creator makes a search and improves at above-mentioned shortcoming, through behind the experimental reconstruction generation of the present utility model being arranged eventually in many ways.

The utility model content

Main purpose of the present utility model, a kind of multi-layer design of low cost of manufacture is being provided, it is made levels with cone and is binded, the papery sound basin of its composition more can increase the high rigid structure of the rigidity of sound basin and the paper-honeycomb of raising the efficiency-paper Sanming City smelting multi-layer sound basin significantly except that having the good characteristic of light weight and papery internal losses.

For reaching aforementioned purpose, a kind of paper-honeycomb-paper sandwich multi-layer sound basin structure that the utility model is set is characterized in that it mainly comprises:

One first cone is the bowl taper of two ends perforate, and the inboard of sound basin is located in the position;

One second cone is the bowl taper of two ends perforate, and the outside of sound basin is located in the position;

One intermediate course is all bowl taper mutually but is honeycomb, is folded in the middle of first and second cone;

One first glue-line is located between first cone and the intermediate course; And

One second glue-line is located between second cone and the intermediate course;

Wherein this vertebra degree of three to group be second cone greater than intermediate course more again greater than first cone, make three's mat gluing closely be one.

Description of drawings

After constitution content of the present utility model and other characteristics can describe in detail in the embodiment of the following conjunction with figs. of reading, and be tending towards clear, wherein:

Fig. 1 is the utility model sound basin structural upright exploded view.

Fig. 2 is the utility model sound basin structural upright constitutional diagram.

Fig. 3 is the utility model part section enlarged drawing.

Fig. 4 is that the utility model is made schematic diagram.

Embodiment

Shown in Fig. 1～4, the set a kind of paper-honeycomb of the utility model-paper sandwich multi-layer sound basin structure, it mainly comprises:

One first cone 1 is the bowl taper of two ends perforate, and the inboard of sound basin is located in the position;

One second cone 2 is the bowl taper of two ends perforate, and the outside of sound basin is located in the position;

One intermediate course 3 is all bowl taper mutually but is honeycomb, is folded in the middle of first and second cone 1,2;

One first glue-line 41 is located between first cone 1 and the intermediate course 3 for cohering; And

One second glue-line 42 is located between second cone 2 and the intermediate course 3 for cohering;

Please join shown in Fig. 1,4, during enforcement this tapering of three to group be second cone 2 greater than intermediate course 3 more again greater than the folded mutually gluing of first cone, 1 three again side repair and constitute together.

When wherein making, behind first cone 1 and second cone, the 2 difference gluing thermocompression formings, gluing together in mould with middle honeycomb interlayer 3 becomes multi-layer sound basin structure again.

Thus, make three's gluing closely form the sound basin of one, not only have outside the good characteristic of light weight and papery internal losses, while can increase the rigidity of sound basin significantly again and raise the efficiency, what more value was carried is to utilize the unlikely too high should cost of cost, can make this sound basin when sound reproduction, the situation of the general distortion of formula sheet-fed goods is practised in unlikely generation.

In sum, the certain available should cost of the utility model solves the shortcoming that known individual sound basin made of paper uses, and function far wins habit formula tool progressive and industrial utilization, so propose novel patent application in accordance with the law.

Above-mentioned specific embodiment is to be used for describing in detail the purpose of this utility model, feature and effect, for people's bodyguard of being familiar with this type of skill, according to the above description, may do partly change and modification to this specific embodiment, its essence does not detach spiritual category person of the present utility model, all should be included in the claim of this case.
