−気抜穴6が設けられでいるものが多いものである。15 is a voice coil bobbin formed by winding this voice coil 14, and this bobbin 15 is attached to a spider 17 with respect to the front frame 16 of the speaker fixed to the magnetic plate 13 etc. that constitute the magnetic circuit 10. and is supported by the IIT rift through the honeycomb diaphragm 1, and its voice coil 14 is positioned in the gap between the protrusion 11a of the pole piece 11 and the magnetic block L/-413. Insert is placed. In addition, 18 in Figure 1 is an edge for connecting the outer peripheral edge of the honeycomb diaphragm 1 to the )1/-m 16 side, and 19 is a dust bonded and fixed with adhesive so as to cover the center part of the honeycomb diaphragm 1. The cap is configured such that the air vent hole 6 is located at a position corresponding to the dust cap 19. This is because, without the air vent hole 6, the air flow inside the dust cap 19 would be poor, and a force that would make it difficult to vibrate would be applied to the honeycomb diaphragm 1, increasing the distortion of the vibration system. In particular, the speaker diaphragm for the low range with a large amplitude is
-Many of them are provided with air vent holes 6.

The protrusion 11a of the pole piece 11! l: As is well known, a magnetic field is generated by a magnetic circuit in the air gap with the magnetic plate 13, and by passing a current through the voice coil 14 inserted in this magnetic air gap, it is driven according to Fleming's left-hand rule. A force is generated which causes the voice coil 14 to
vibrates, and this vibration is transmitted to the honeycomb diaphragm 1 side via the pobbin 15, and as the honeycomb diaphragm 1 vibrates, sound is radiated to the outside.

Chips or the like may occur in the inner skin materials 3 and 4, or chips from the core 2 or skin materials 3.4 may remain in the air vent hole 6, requiring troublesome work to remove them. In particular, if these chips get into the cells of the honeycomb core 2, it is practically impossible to completely remove them, so when this honeycomb diaphragm 1 is incorporated into a speaker device to generate sound. In addition, there were problems such as causing chatter phenomena.

た種々優れた効果がある。As explained below, according to the method for manufacturing a honeycomb diaphragm according to the present invention, the honeycomb diaphragm is formed of a honeycomb core and front and back skin materials laminated and attached to the front and back surfaces of the honeycomb core, and air is injected into predetermined portions of the honeycomb core. A honeycomb diaphragm with punched holes,
Air vent holes are drilled in the front and back skin materials as a pre-processing process, and then these front and back skin materials are used as the front and back skins of the honeycomb core.
Since it is formed by adhering it to the back side, there is no chipping of the core or skin material near the air vent hole, which is the case with conventional methods, even though it is inside the cylinder and is an inexpensive method. There is no problem of air remaining in the hole or the need to remove it, and as a result, when this is incorporated into a speaker device, for example, there is no problem of chatter occurring due to the air vent hole. It has various excellent effects such as being able to easily form a stable honeycomb and diaphragm.
