Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to fig. 2, it is a schematic structural diagram of an elliptical voice coil according to the present invention. The voice coil oval includes a bobbin 10, a coil assembly 20 wound around the bobbin 10, and a reinforcing paper 30 wrapped around the outer side wall of the bobbin 10, and further includes other functional modules, such as adhesive, etc., which should be known to those skilled in the art, and will not be described in detail herein.

The skeleton 10 is a tubular structure, and the outer contour is an ellipse. The frame 10 may be made of a light metal material such as aluminum or aluminum alloy, so that its own weight is reduced and it is applicable to a small-sized speaker. The thickness of the framework 10 is 0.05 mm-0.1 mm. The oval design of skeleton 10 makes it can be applicable to various small-size electrical apparatus, and space utilization is higher, and can not influence the power size of speaker.

The coil assembly 20 includes at least one layer of coil 21 wound on the frame 10, and two lead wires 22 led out from the head and tail ends of the coil 21. The height of the coil 21 is less than that of the framework 10, so that the framework 10 has a larger heat dissipation area after the coil 21 is wound on the framework 10. The two lead wires 22 are led out from the head end and the tail end of the coil 21, respectively. The specific structure of the lead 22 and the frame 10 will be described in detail in conjunction with the reinforcing paper 30, in which the lead 22 is attached and fixed to the reinforcing paper 30, and the reinforcing paper 30 passes through the lead 22. It is contemplated that the two leads 22 are always positioned on opposite outer sidewalls of the bobbin 10 for connection to an external device cone (not shown) for conducting current to the coil assembly 20. The leads 22 may be axially parallel or perpendicular to the frame 10, enabling it to be adapted to different horn needs. In the present embodiment, the lead 22 is perpendicular to the axial direction of the bobbin 10.

The reinforcing paper 30 is wrapped on the outer side wall of the framework 10 and comprises two lead ports 31 which are respectively positioned on two opposite outer side walls of the framework 10. The reinforcing paper 30 is a rectangular structure, and the length of the reinforcing paper is greater than or equal to the perimeter of the outer side wall of the framework 10, so that the reinforcing paper can be wound for at least one circle when wound on the outer side wall of the framework 10. The reinforcing paper 30 wraps the lead 22 between the reinforcing paper 30 and the outer side wall of the framework 10, so that the stability of the lead 22 is improved, and meanwhile, the insulation between the lead 22 and the framework 10 is also provided. The lead wire port 31 is located inside the reinforcing wire 30, that is, the lead wire port 31 and two sides of the reinforcing paper 30 are arranged at intervals, and the extending direction of the lead wire port 31 is perpendicular to or parallel to the axial direction of the framework 11, so that the lead wire 22 can have two different wire outlet modes. The lead port 31 is used for extending the two leads 22 from the lead ports 31 at two different positions, respectively. It is conceivable that the extending direction of the opening of the lead port 31 is the extending direction of the lead 22, the number of the lead ports 31 is the same as the number of the lead 22, and the length of the opening of the lead port 31 can be designed according to actual requirements.

Compared with the prior art, the utility model provides an oval voice coil loudspeaker voice coil passes through skeleton 10 designs into oval, makes oval voice coil loudspeaker voice coil can satisfy the constrictive electrical apparatus speaker demand in various positions on the market. The reinforcing paper 30 is wound on the outer side wall of the framework 10, and a lead port 31 is formed in the reinforcing paper, so that the position of the lead 22 can be positioned, and insulation between the lead 22 and the framework 10 can be provided. In addition, the lead 22 may have two different wire outgoing manners as required to facilitate connection with the braided wire of the cone, and to make the elliptical voice coil more versatile.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
