DESCRIPTION JP2003224897
[0001]
The present invention relates to a conductive hanger plate portion provided on an outer surface
of a microphone case and electrically connected to a circuit board in the microphone case, and
the hanger on the hanger plate portion. It is provided in a state in which conduction by direct
contact with the plate portion is prohibited, and has a conductive hanger knob electrically
connected to the circuit board in the microphone, and the hanger knob is hooked to the
conductive microphone hanger. When it stops, it is related with the hanger switch structure of
the microphone comprised so that conduction ¦ electrical̲connection with the said hanger plate
and the said hanger knob might be made via this microphone hanger.
[0002]
2. Description of the Related Art As shown in FIG. 10, a microphone 3 connected to a
communication apparatus main body via a cord 1 has a hanger knob 5 comprising a shaft 5a and
a flange 5b on its back surface, There is a device in which the shaft 5 a of the knob 5 is inserted
through the slit 7 a of the microphone hanger 7 so that the microphone 3 can be hooked to the
microphone hanger 7.
[0003]
And, in the microphone 3 of such a configuration, there is one having a mechanism called a
hanger switch in order to detect that the microphone 3 is hooked to the microphone hanger 7.
[0004]

A hanger switch structure of a conventional microphone will be described with reference to FIG.
11 which is a cross-sectional view taken along line A-A of FIGS.
As shown in FIG. 10, a hanger plate 9 made of a conductive plate is disposed on the back side of
the microphone 3.
In the vicinity of the four corners of the hanger plate 9, four substantially C-shaped slits 9a are
formed, and therefore, a tongue-like resilient pressing portion 9b is formed inside the slits 9a.
[0005]
As shown in FIG. 11, the resilient pressing portion 9b is formed so as to project in a spherical
shape toward the back side. A circular through hole 9 c is formed at the center of the hanger
plate 9. At a position opposite to the hanger plate 9 in the microphone 3, a cylindrical portion 3c
in which a stepped through hole 3a is formed is formed.
[0006]
An insulating ring 11 made of a flanged cylindrical insulating material is inserted into the
through hole 9 c of the hanger plate 9 and the cylindrical portion 3 c of the microphone 3 so as
to press the hanger plate 9 from the back side of the microphone 3. The shaft 5a of the knob 5 is
inserted into the inner cylindrical surface of the insulating ring 11, and the knob 5 is fixed by a
screw 13 inserted through the through hole 3a. The hanger knob 5 is made of a conductive
material.
[0007]
Accordingly, conduction between the knob 5 and the hanger plate 9 due to direct contact is
prohibited by the insulating ring 11. On the other hand, the microphone hanger 7 is also made of
a conductive material, and as shown in FIG. 10, the base end is attached to the top of the
microphone hanger 7 and the tip end side is a conductive material extending in the direction of
01-05-2019

the slit 7a. A supporting spring 8 is provided.
[0008]
Then, when the microphone 3 is hooked to the microphone hanger 7, as shown in FIG. 11, the
elastic pressing portion 9a of the hanger plate 9 presses the microphone hanger 7, and the
support spring 8 is held in the recess 5c of the flange portion 5b of the hanger knob 5. The
projections 8a of the two are engaged. Therefore, when the hanger knob 5 is hooked to the
microphone hanger 7, conduction between the hanger plate 9 and the hanger knob 5 is made via
the microphone hanger 7.
[0009]
In the above-described conventional structure, the feeling of attachment and holding power when
the hanger knob 5 is hooked to the microphone hanger 7 is determined by attaching the resilient
pressing portion 9b of the hanger plate 9 to the microphone hanger 7. It depends on pressing
force.
[0010]
However, the resilient pressing portion 9 b is formed by projecting the inside of the substantially
C-shaped slit 9 a punched out on the hanger plate 9 into a spherical shape.
Therefore, although the pressing force is substantially determined by the diameter of the
substantially C-shaped slit and the width of the slit, the degree of freedom in design is small due
to the size of the hanger plate 9 and the relationship with the hanger knob 5 There are problems
that are difficult to get.
[0011]
Also, when the microphone 3 is hooked to the microphone hanger 7 and when the microphone 3
is removed from the microphone hanger 7, the impact acting on the microphone 3 is
concentrated on the resilient pressing portion 9b, so fatigue of the resilient pressing portion 9b
is fast. There is also a problem that is not durable.
