Abstract
The utility model discloses a speech coil framework prepared from an aluminum foil compound glass fiber material. The speech coil framework comprises a tubular body having a hollow through hole. The tubular body is prepared from the aluminum foil compound glass fiber material which contains an aluminum foil layer for winding and contacting of speech coils and a glass fiber layer coated on the surface of the aluminum foil layer. By coating the aluminum foil layer with the glass fiber layer, the aluminum foil compound glass fiber material is formed. By the utilization of the material for the production of the speech coil framework, defects of separately using a metallic aluminum material or glass fiber in the prior art can be solved effectively. Bone quality of both metallic aluminum and glass fiber is considered. Thus, bone quality of a loudspeaker can be improved greatly, and high pitch can be more mellow and full. The speech coil framework provided by the utility model is worth of wide popularization and application.
Description
Technical field
The utility model relates to speech coil framework art, refers in particular to a kind of speech coil framework that uses aluminium foil composite glass fiber material.
Background technology
Speech coil framework is the bone network of whole voice coil loudspeaker voice coil, undertakes work the source of sound actuating force of voice coil loudspeaker voice coil generation is transferred to the responsibility that becomes radiation diffusion on vibrating diaphragm, requires speech coil framework light, and rigidity is large again, and it is smooth smooth that skeleton inner surface is wanted, after coating processing, also high temperature resistant.
When making speech coil framework, be generally to adopt metallic aluminum material or glass fibre; The rigidity of metallic aluminum material is enough, when but metallic aluminum material is done speech coil framework, because metallic aluminium density is larger, cause the weight of speech coil framework itself to increase, and with metallic aluminum material, do speech coil framework and can make loudspeaker can produce eddy current when operating, cause the eddy current loss of loudspeaker work.And the density of glass fibre only has 1.5*10
3kg/m
3, compare metallic aluminum material density and want little by approximately 45%, adopt this kind of material to do speech coil framework, because glass fibre weight kicks the beam, rigidity is poor, and loudspeaker high frequency performance when work is poor.
Utility model content
In view of this, the utility model is for the disappearance of prior art existence, its main purpose is to provide a kind of speech coil framework that uses aluminium foil composite glass fiber material, and it can effectively solve eddy current loss or the poor problem of high frequency performance that existing speech coil framework can cause loudspeaker work.
For achieving the above object, the utility model adopts following technical scheme:
A kind of speech coil framework that uses aluminium foil composite glass fiber material, include tubular body, this tubular body has hollow via-hole, this tubular body is aluminium foil composite glass fiber material, and this aluminium foil composite glass fiber material includes for voice coil loudspeaker voice coil and is wound around the aluminium foil layer of contact and is covered in the lip-deep glass layer of aluminium foil layer.
Preferably, described glass layer adopts glue to be compound on the surface of aluminium foil layer with hot pressing mode.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, and as shown from the above technical solution:
By cover glass fibrage on aluminium foil layer, with this, form aluminium foil composite glass fiber material, the speech coil framework that utilizes this kind of material to make can effectively solve independent metallic aluminum material or the existing defect of glass fibre of adopting in prior art, the utility model has been taken into account the acoustic feature of metallic aluminium and glass fibre, can significantly improve the tonequality of loudspeaker, make high pitch more mellow and fuller, use should be widely promoted.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the preferred embodiment of the utility model;
Fig. 2 is the sectional view of aluminium foil composite glass fiber material in the preferred embodiment of the utility model.
Accompanying drawing identifier declaration:
10, tubular body 11, aluminium foil layer
12, glass layer 101, hollow via-hole
Embodiment
Please refer to shown in Fig. 1 and Fig. 2, the concrete structure that it has demonstrated the preferred embodiment of the utility model, includes tubular body 10.
This tubular body 10 has hollow via-hole 101, this tubular body 10 is aluminium foil composite glass fiber material, this aluminium foil composite glass fiber material includes for voice coil loudspeaker voice coil (not shown) and is wound around the aluminium foil layer 11 of contact and is covered in the lip-deep glass layer 12 of aluminium foil layer 11, and this glass layer 12 adopts glue to be compound on the surface of aluminium foil layer 11 with hot pressing mode.
During making, first with hot pressing mode, glass layer 12 is compound with glue on the surface of aluminium foil layer 11, thickness selection aspect can by different-thickness surface on glue with hot pressing mode, glass layer 12 is compound, the compound key point of aluminium foil layer 11 and glass layer 12 is that the material after compound needs even, smooth, without foaming, gap, come off, interlayer glue wants to bear the test of-40 ℃～140 ℃, relative humidity RH 95% and 100 hours.Thickness selection aspect can be carried out the aluminium foil layer of different-thickness 11 and glass layer 12 compound, then at aluminium foil layer 11 surface sizing water, to be used for around voice coil loudspeaker voice coil operation.
Design focal point of the present utility model is: by cover glass fibrage on aluminium foil layer, with this, form aluminium foil composite glass fiber material, the speech coil framework that utilizes this kind of material to make can effectively solve independent metallic aluminum material or the existing defect of glass fibre of adopting in prior art, the utility model has been taken into account the acoustic feature of metallic aluminium and glass fibre, can significantly improve the tonequality of loudspeaker, make high pitch more mellow and fuller, use should be widely promoted.
Know-why of the present utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection range.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present utility model, within these modes all will fall into protection range of the present utility model.
