Abstract

PURPOSE:To improve the bonding strength between a voice coil bobbin and a wire and to improve the space factor of a voice coil conductor in a magnetic air gap by applying an insulation film to a conductor peripheral and using the wire whose conductor cross section is a square so as to form the voice coil. CONSTITUTION:The cross section of the conductor 11 applied with the insulation film 12 at the peripheral is circular, a round wire used as a wire for a speaker voice coil more prevailing than a conventional coil is pressed in the direction of A to form the cross section of the conductor 11 to be nearly proper elliptic shape and pressed in a major axis direction (direction B), thereby forming a wire 13 the cross section of the conductor 11 of which is square. The wire 13 is wound on the voice coil bobbin 14 by a prescribed number of layers via an adhesive layer.

2. Description of the Related Art Conventionally, this type of speaker voice coil has had a structure as shown in FIG. 3, for example. In FIG. 3(a), reference numeral 1 denotes a conductor wire having a circular cross-section with an insulating coating 2 applied to the outer periphery, and is wound around a voice coil bobbin 3 in a desired number of layers to form a voice coil. Also, with the recent demand for higher efficiency speakers, in order to increase their efficiency, 1. The Edge Quiz wire, which has a high-density voice coil conductor wire, was used. That is, as shown in FIGS. 3(b) and 3(c), a conductor wire 5 having a rectangular cross section and an insulating coating 4 on the outer periphery is connected to the voice coil bobbin 3, and the long side or short side of the cross section is connected to the coil IB bin. The winding of 3 is surface 3a
The structure was formed by winding the desired number of layers parallel to the .

Problem to be Solved by the Invention In order to improve the efficiency of fish speakers, edgewise wires are required, but when wound as shown in FIG. is the conventional round wire insulation layer 2
Since the thickness of the conductor is considerably larger than that of the conductor, the occupancy rate of the conductor in the magnetic gap does not increase very much, and the effect of making the speaker highly efficient cannot be obtained. Also, Figure 3 (C)
If the coil is wound as shown in the figure, there is a problem that the adhesive strength between the coil bobbin 3 and the wire 6 is weakened because there are few adhesive parts of the wire 6 to the voice coil bobbin 3, and the wire winding process requires a considerable number of man-hours. There is a problem that workability deteriorates.

Effect In the above configuration, by making the cross-sectional shape of the conductor with an insulating coating on the outer periphery of the conductor square, the thickness of the insulating layer in the winding direction becomes the same as that of a conventional round wire, and the occupation of the conductor in the magnetic gap is reduced. You can increase the rate. Moreover, the bonding area of the wire to the voice coil bobbin becomes wider, and the bonding strength between the voice coil bobbin and the wire can be improved. Furthermore, when winding around the voice coil bobbin, since the cross section is square, it is possible to wind it with the same workability as round wire.
