Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a composite speaker, more specifically known as a tinsel wire. This invention relates to a composite speaker with improved lead wire forming work.

[Conventional technology]

For conventional well-known composite speakers, such as cone-shaped bass speakers, A composite speaker configured by coaxially arranging cone-shaped mid-high frequency speakers is shown in Figure 5. , as shown in Figure 6, there is a lead that supplies the drive signal to the voice coil of the bass speaker. One end of the lead wire 1 is connected to the input terminal board 2, and the other end is connected to the bass speaker. It is inserted into the hole 3a drilled in the diaphragm 3 from the rear side of the diaphragm 3, and tied at the front side. The hook part 1a such as the eye is fixed to the diaphragm 3 with adhesive, and the vibration is transmitted again from the hole 3a. It is led out to the rear side of the plate 3 and led out again to the front side through a hole 3b drilled near the edge 4. and is fixed to the input terminal board 5 of the medium and high frequency speaker.

0003 Then, one of the power supply lines 8 to the voice coil 7 is connected to the lead wire 1 fixed to the diaphragm 3. One end is fixed with solder, and the other end extends to the voice coil 7 to drive the diaphragm 3. A path is formed.

0004 Further, as shown in FIG. 7 and FIG. 8, the hole 3a of the diaphragm 3 is divided into two parts. A disc-shaped stopper 8 is provided, and the lead wire 1 is folded back by this stopper 8. Also known is a structure in which the diaphragm 3 extends from another hole 3b to the front side of the diaphragm 3. As a concrete precedent example of these, Utility Model Application Publication No. 59-99599 can be mentioned. Wear.

[0005] Furthermore, as shown in FIGS. 9 and 10, the lead wire 1 is 3a, is guided to the rear side of the diaphragm 3 from another hole 3b, and is then guided through another hole 3c. After being led out to the front side of the diaphragm 3 and fixed with adhesive, a mid-high frequency speaker is attached. The lead wire connected to the input terminal board 5 of the input terminal board 5 using the so-called sewing method It is also known that the characters are rotated.

[0006]

[Problem that the idea aims to solve]

Composite type speakers according to the conventional examples shown in FIGS. 5, 6, 7, and 8 as described above In this case, a locking device or a knob-like knot on the lead wire is required. Therefore, if the output of the speaker is high, it is natural that the lead wire is It is also thick, so in this case, the part with the anti-slip measures becomes large and heavy. Even if it is fixed with solder, the amount of solder increases and the weight of the diaphragm 3 increases due to the weight variation. This may cause the vibration to be disturbed, causing abnormal resonance due to rolling, or causing large inputs. When there is force, the voice coil 7 and the top plate of the magnetic circuit come into contact. It is also the cause.

[0007] In addition, in order to reinsert the lead wire 1 into the hole 3a of the diaphragm 3 after bending it, a hole is inserted. It takes time and effort to do this work, and additionally, it is necessary to use adhesive after drilling the hole. Since the adhesive fixation is not completely fixed, the voice coil and lead Failures such as disconnections often occurred after connecting to the cable.

[0008] Generally, lead wires have a uniform thickness, so there is a possibility of wire breakage or problems with forming. If a conflict occurs, change the thickness of the other lead wires so that all lead wires have the same thickness. The need to unify the system also causes costs to rise.

[0009] Due to the use of adhesive, aging is required until the adhesive hardens. There is a problem that requires a lot of work time to complete.

0010 Furthermore, in the conventional composite type speaker shown in FIGS. 9 and 10, the lead wire 1 is The sewing work is complicated, and the lead wires are fixed with adhesive, so it is not completely It is difficult to fix the voice coil 7 and the lead wire 1 with solder, and the wire may break after fixing the voice coil 7 and lead wire 1. The problem was that accidents were likely to occur.

[0011] Therefore, this idea improves the weight balance of the diaphragm and eliminates the need for complicated lead wires. To provide a composite speaker that does not require drilling work or fixing work using adhesives. The purpose is to
