ABSTRACT:
TECHNICAL FIELD
The present invention relates to a microphone holder. In particular, the present invention relates to a microphone holder in which the microphone is held inside a microphone casing so as to be able to electrically connect to an outer component via a connecting terminal.
BACKGROUND ART
Conventionally, for example, a microphone is provided in a casing of a mobile phone and a transceiver, and a microphone holder is used for holding the microphone in a predetermined position. From the viewpoint of required functions, the microphone holder must maintain electrical contact between the microphone and the outer component such as a printed circuit board and must hold the microphone tightly. For that purpose, a microphone holder
50
, as shown in
FIG. 4
showing a conventional microphone holder, which can contain the microphone inside the microphone holder and can electrically connect the microphone and the outer section is proposed in, for example, Japanese Application No. Hei 10-178285.
The microphone holder
50
as shown in
FIG. 4
comprises a rubber holder having approximately the same internal circumferential shape as the external circumferential shape of the microphone
51
, a circumferential section
54
able to accept the rubber holder
52
, a plurality of supporting plate section
55
provided on the bottom end of the circumferential section
54
, a pair of foot sections
57
extending downward from the bottom end of the circumferential section
54
and which can be engaged with the outer section
56
. On the bottom end of the rubber holder
52
, an engaging projection part
59
is provided so as to be able to be engaged with a hole
55
A provided on each supporting plate
55
. An operation of attaching a microphone
51
to the microphone holder
50
is performed such that a microphone
51
is contained in a rubber holder
52
, each engaging projection part
59
is engaged in a hole
55
A, and a rib
61
of a front casing
60
pushes the top surface of the rubber holder
52
.
However, in such a microphone holder
50
, the structure of the microphone holder
50
not only becomes complicated, but there is also an disadvantage in that a plurality of components must be assembled so as to hold the microphone
51
tightly. Also, in order to achieve the electrical connectivity between the microphone
51
and the outer section
56
, connecting operations such as soldering are inevitably required, and this connecting operation is disadvantageously burdensome. Furthermore, the rubber holder
52
and the circumferential section
54
have a space penetrating along the axial direction; thus, there is a disadvantage, called sound-leakage in which the sound input from the top surface of the microphone
51
leaks downward.
DISCLOSURE OF INVENTION
This invention was made in consideration of solving the above problems, and an object of the invention is to provide a microphone holder which can tightly hold a microphone located inside the holder casing while maintaining the electrical contact between the microphone and the predetermined outer section favorably so as to be able to attach the microphone to the holder casing easily.
In order to achieve above the object, a microphone holder of the present invention comprises a holder casing having an opening section in one end of which holder casing a microphone can be inserted and a microphone fall-off prevention section for holding the microphone, a connecting terminal supported by the holder casing so as to electrically connect the microphone inside the holder casing and a predetermined outer section. By this structure, it is possible to tightly hold the microphone inserted in the holder casing while maintaining the electrical connectivity between the microphone and the external section; thus, the disadvantages, such as a fall-off of a microphone from the holder casing, can be avoided effectively.
