イスコイル製造方法である。<Conventional technology> A voice coil of a speaker is formed by inserting a paper bobbin wound in a cylindrical shape into a winding core, winding the required number of coils through a winding machine, drying the adhesive, and winding the coil electric wire. The lead wires at the beginning and end of the winding are arranged in parallel on the winding core to prepare for the soldering connection with the tinsel wire on the next bobbin. As a prior art, Japanese Patent Application Laid-Open No. Sho 60-237800 or Japanese Patent Publication No. Sho 49-3164
No. 6 discloses a method of manufacturing a voice coil which is the first.
As shown in FIGS. 4 to 16, a tinsel wire (3) is attached to the voice coil thus prepared, and two pieces of the twin coil wire (3) are arranged in parallel at a distance from the center of the tinsel wire (3). Press the blades (39) and (39) and cut at two locations. And
This is a voice coil manufacturing method in which a coil lead wire is wound around both ends of a cut end of a tinsel wire (35) from which intermediate chips have been removed and soldered.

Is cut by pressing against the bobbin (31) from above, so that when the tinsel wire (3) is cut, the paper bobbin (31) located immediately below the tinsel wire also has a cutting edge (39), (3
It is inevitable that 9) cuts into the bobbin (31) and cuts two rows (36) and (36) in the vertical direction. Therefore, the bobbin (31) is mechanically weakened by the cuts (36) and (36), so that it is difficult to handle in the assembling process, it is difficult to keep a perfect circle, and the outer shape is easily distorted. When assembling into a speaker, when assembled into a narrow magnetic gap, there is a defect in that it contacts a wall of the gap and becomes defective, or cannot withstand vibration during use.
本発明は、このような欠点を解消して、真円形を保持

スコイルが完成する。Above the bobbin (1) fitted to the winding core (2),
The tinsel wire (3) cut into unit lengths is clamped and fixed. At this stage, the lead wires (4) and (4) at both ends of the voice coil are placed on the bobbin (1) at regular intervals, and the two-stage wires positioned above the lead wires (4) and (4) The hot plate (8) directly connected to the heating element (7) attached to the air cylinder (16) of Mosion is brought close to the tinsel wire (3). The tinsel wire (3) is sandwiched in the gap (25) between the heat-resistant material guides (9) and (9 ') sliding up and down on both sides of the hot plate (8). Both ends are Kinshi Line (3)
Stop once at the point where it touches. Thus, Guide (9),
The tinsel wire (3) straddling the concave notch (23) formed in the center of the tip of (9 ') is cut by another air nipper (22). At that time, the tinsel wire (3) remains in the gap (25) between the guides (9) and (9 ') while being cut. At this time, the cut end of the tinsel wire (3) has not yet contacted the lead wires (4), 4) at the beginning and end of winding of the voice coil. Next, when the clampers (17) and (18) are lowered by the elevator and the hot plate (8) is further driven and pressed by the air cylinder, the curved surfaces at the tips of the guides (9) and (9 ') become bobbin. The hot plate (8) slides between the guides (9) and (9 ') by pressing against the outer periphery of (1), and when pressed further, overcomes the elasticity of the spring (24) to slide the tinsel wire (3). And presses the bobbin (1). then,
The curved surface at the tip of the hot plate (8) presses the cut ends of the tinsel wire (3) along the outer periphery of the bobbin (1). When appropriate, the cut ends of the tinsel wire (3) are spaced apart, and the lead wires (4), (4) at the end of the winding start and end of the voice coil placed on the bobbin (1) ). At this time, both ends of the tinsel wire (3) are bonded to the thermoplastic adhesive (2) which has been applied to the upper surface of the bobbin (1) in advance.
By 9), it is thermally fused to the bobbin (1). As described above, the guides (9) and (9 ') serve to hold the tinsel wire (3) so as not to come off from the cutting of the tinsel wire (3) to the heat fusion. Then, after the hot plate (8) is removed and the adhesive is solidified, the lead wires (4) and (4) at the beginning and end of winding of the voice coil are bent so as to wrap the tinsel film (3) and soldered. After making the connection, trimming the ends, removing the clampers (17) and (18) and detaching them from the winding core (2), the voice coil is completed.
