Abstract
The utility model discloses an improvement type voice coil loudspeaker voice coil, it includes: a flexible skeleton and around locating the coil on the skeleton, this coil closely comprises on locating the skeleton the copper line, copper line, copper -clad aluminum wire constitute by copper line two strands at least, copper -clad aluminum wire intertwine obvolvent. The utility model discloses simple structure, manufacturing convenience, the skeleton adopts paper, plastics or aluminum sheet to make, can cross and produce certain deformation, makes things convenient for the equipment of voice coil loudspeaker voice coil, in addition, the adoption constitutes the coil on locating the skeleton by the copper wire -wound of stranded copper wire obvolvent formation, makes its high frequency efficiency of voice coil loudspeaker voice coil of making better, more powerful than adopting simple strand copper wire to cross, the utility model provides an adopt the mutual obvolvent of stranded copper wire to make the wire rod to make the coil by this copper line, copper -clad aluminum wire, make voice coil loudspeaker voice coil weight lighter, improve its power and be difficult to the broken string, thereby promoted efficiency, the resources are saved cost.
Description
Technical field:
The utility model relates to voice coil loudspeaker voice coil technical field, refers in particular to a kind of modified form voice coil loudspeaker voice coil.
Background technology:
Voice coil loudspeaker voice coil is one of significant components of loud speaker, and when alternation tone currents is by voice coil loudspeaker voice coil, make voice coil loudspeaker voice coil produce the alternating current changed with audio frequency, cutting magnetic line produces mechanical oscillation, drives cone vibration to sound.Voice coil loudspeaker voice coil is the critical component determining loud speaker useful life, and its operation principle is: when alternation tone currents is by voice coil loudspeaker voice coil, and make voice coil loudspeaker voice coil produce the alternating current changed with audio frequency, cutting magnetic line manufacturing machine vibrates, and drives basin vibration of shaking to sound.The quality of voice coil loudspeaker voice coil is with making the material, coil winding, shape etc. of voice coil loudspeaker voice coil by relation.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of modified form voice coil loudspeaker voice coil.
In order to solve the problems of the technologies described above, the utility model have employed following technical proposals: modified form voice coil loudspeaker voice coil, it comprises: the skeleton of a flexibility and the coil be set around on skeleton, this coil is closely set around on skeleton by copper cash and forms, and described copper cash is mutually wound around obvolvent by the copper wire of at least two strands and forms.
Furthermore, in technique scheme, described skeleton is hollow cylindrical, adopts plastic cement integrated injection molding.
Furthermore, in technique scheme, described skeleton is hollow cylindrical, and adopts aluminium flake to make.
Furthermore, in technique scheme, its outer surface of described skeleton is smooth shape, and described copper cash is evenly set around skeleton outer surface, and is arranged with 15-300 circle.
Furthermore, in technique scheme, its outer surface of described skeleton is arranged with 1-30 layer copper cash.
Furthermore, in technique scheme, its outer surface of described skeleton forms the spacing preiection preventing coil to be shifted up and down.
Furthermore, in technique scheme, described copper cash is made up of 4 bursts of tight obvolvents of copper wire.
After adopting technique scheme, the utility model has following beneficial effect compared with prior art:
1, the utility model structure is simple, easily manufactured, and skeleton adopts paper, plastics or aluminium flake to make, and can cross the deformation producing certain Chengdu, facilitate the assembling of voice coil loudspeaker voice coil; In addition, adopt the copper cash formed by stranded copper wire obvolvent to be set around on skeleton and form coil, better, more powerful than adopting the copper wire of sub-thread can cross its high frequency efficiency of voice coil loudspeaker voice coil making to make;
2, copper cash is made in the mutual obvolvent of employing stranded copper wire in the utility model, and makes coil by this copper cash, make voice coil loudspeaker voice coil weight lighter, improve its power and be not easy broken string, thus improve efficiency, economize on resources cost.
Accompanying drawing illustrates:
Fig. 1 is stereogram of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is the structural representation of copper cash in the utility model.
Embodiment:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
See shown in Fig. 1-3, modified form voice coil loudspeaker voice coil, it comprises: the skeleton 1 of a flexibility and the coil 2 be set around on skeleton 1, and this coil 2 is closely set around on skeleton 1 by copper cash 21 and forms, and described copper cash 21 is mutually wound around obvolvent by the copper wire 211 of at least two strands and forms.
Described skeleton 1 is hollow cylindrical, and paper, plastic cement, aluminium flake etc. can be adopted to be made into integration, and skeleton 1 can the trickle elastic deformation of product, facilitates it to be assembled in loud speaker.
Described its outer surface of skeleton 1 is smooth shape, described copper cash 21 is evenly set around skeleton 1 outer surface, and be arranged with 15-300 circle, its outer surface of skeleton 1 is arranged with 1-30 layer copper cash 21, copper cash 21 is made up of the mutual obvolvent of at least two strands of copper wires 211, and the copper cash 21 in the present embodiment is made up of the mutual obvolvent of 4 strands of copper wires 211.In addition, its outer surface of skeleton 1 forms the spacing preiection 21 preventing coil about 2 to be shifted.
Copper cash is made in the mutual obvolvent of employing stranded copper wire in the utility model, and makes coil by this copper cash, make voice coil loudspeaker voice coil weight lighter, improve its power and be not easy broken string, thus improve efficiency, economize on resources cost.
Certainly, the foregoing is only specific embodiment of the utility model, be not limit the utility model practical range, all equivalences done according to structure, feature and principle described in the utility model claim change or modify, and all should be included in the utility model claim.
