Abstract
The utility model discloses a double-wire parallel wound voice coil, comprising a skeleton (1) and a coil (2) which winds the skeleton. The coil (2) is formed by two enamel covered wires winding side by side. The two enamel covered wires are welded together side by side at a wire end (3). When the cross section area of the two wires and the cross section area of a single wire are identical, the surface area of the two wires is larger than the surface area of a single wire, the effective resistance to the current with higher frequency is decreased, and therefore, some enamel covered wires can be adopted. When the circle number and the width of the coil are identical, the thickness and the weight of the coil are reduced, therefore, the weight of the voice coil can be decreased, and the sensibility of the voice coil is improved. The thickness of the voice coil is decreased, the magnetic interval can be decreased, and the output power is enlarged.
Description
Technical field
The utility model relates to a kind of structure of loudspeaker voice coil, a kind of two-wire and around voice coil loudspeaker voice coil.
Background technology
Voice coil loudspeaker voice coil is the driving element of loud speaker, comprises skeleton and the coil two parts on the skeleton.Skeleton adopts the metal material of paper, engineering plastics or non-magnetic conduction to make, and coil adopts enamelled wire, outside skeleton, generally is all the multilayer lap wound.Voice coil loudspeaker voice coil when work, in the coil by tone currents, the effect that voice coil loudspeaker voice coil is magnetic field force induced and vibrating.The voice coil loudspeaker voice coil of supersound projector particularly, the line footpath of its coil is thicker, and the weight of coil is also bigger, and inertia is bigger, thereby sensitivity is influenced.
Summary of the invention
The utility model is intended to propose the structure of the higher voice coil loudspeaker voice coil of a kind of sensitivity, a kind of two-wire and around voice coil loudspeaker voice coil.
This two-wire and around voice coil loudspeaker voice coil comprises skeleton and the coil on the skeleton.Described coil is to be formed by the coiling arranged side by side mutually of two enamelled wires, and two enamelled wires weld together mutually side by side at the end of a thread place.
This two-wire and around voice coil loudspeaker voice coil because its coil is to form with the coiling arranged side by side mutually of two enamelled wires, the sectional area of two-wire when identical with the sectional area of solid wire, the surface area of two-wire is bigger than single line, the effective resistance of higher frequency current response is reduced, thereby can select thinner enamelled wire for use.Identical at wire circle, when width is identical, the thickness and the weight of coil all reduce, thereby can reduce the weight of voice coil loudspeaker voice coil, improve the sensitivity of voice coil loudspeaker voice coil.And the thickness of voice coil loudspeaker voice coil reduces, and can reduce magnetic gap, increases power output.
Description of drawings
Accompanying drawing 1 is a this two-wire and around the structural representation of voice coil loudspeaker voice coil.
Embodiment
As shown in Figure 1, this two-wire and comprise skeleton 1 and the coil 2 on the skeleton around voice coil loudspeaker voice coil.Described coil 2 is to be formed by the coiling arranged side by side mutually of two enamelled wires.Two enamelled wires weld together mutually side by side at the end of a thread 3 places.
Claims (1)
1, a kind of two-wire and around voice coil loudspeaker voice coil comprises skeleton (1) and the coil (2) on the skeleton, it is characterized in that described coil be by two enamelled wires mutually side by side coiling form, two enamelled wires are located to weld together side by side mutually at the end of a thread (3).
