摘要：
PROBLEM TO BE SOLVED: To provide a condenser headphone unit having a diaphragm
with a conductive coating and an insulation coating formed thereon in which an electrode
is surely led out from the diaphragm.
SOLUTION: The condenser headphone unit includes: a diaphragm 12 provided in
tension on a support ring 11; and fixed pole plates 20 disposed oppositely on at least
one surface of the diaphragm 12 via a spacer member 240, wherein a conductive coating
and an insulation coating are formed like a laminate on the diaphragm 12. In this unit, a
circuit board is used as each of the fixed pole plates 20, a fixed electrode part 210 is
formed on a surface of the fixed pole plate 20 which opposes an effective vibration part
of the diaphragm 12, peripheral electrode parts 220 are circularly formed around the
fixed electrode parts 210 via an electric insulating region 230, pile materials 241 having
conductivity are hair-transplanted on the peripheral electrode parts 220 via a conductive
adhesive, the diaphragm 12 and the fixed pole plates 20 are oppositely disposed while
using the pile materials 241 as a spacer member 240, and the conductive coating of the
diaphragm 12 is electrically connected to the peripheral electrode parts 220 via the pile
materials 241.
