Abstract
PURPOSE:To increase greatly the volume content factor at the coil part and thus to enhance the acoustic conversion efficiency of the speaker by cutting the thickness of the voice coil down to half or less in case the impedance of the voice coil is set identical. CONSTITUTION:Photo resist 2 functioning as the photosensitive material is coated on cylindrical bobbin substrate 1 which is formed with Al of a fixed thickness. Then the light is exposed to substrate 1 coated with resist 2 in the spiral form and with a fixed space in the longer direction of the substrate, thus forming exposure photo resist 3. Then exposed substrate 1 is soaked into the developer for the photo resist in order to remove resist 2 at the end area of resist 3. After this, resist 2 is dissolved away, and the anode oxidation is applied to exposed substrate 1. Then Al layer 4 reaching up to the inner circumference surface of the Al of substrate 1 is formed into a spiral form. And the Al of substrate 1 is divided into round forms to from coil part 5, and then resist 2 remaining on the outer circumference surface of substrate 1 is removed.
