ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a connection seat for mounting a microphone which is exclusively used in conjunction with a musical instrument.
BACKGROUND OF THE INVENTION
The microphones are often used in the concert to amplify the sounds produced by various musical instruments, such as tom-toms, cymbals, etc. As shown in
FIG. 1
, a microphone connection seat
1
of the prior art is provided with a threaded hole
2
and a plug receptacle
3
contiguous to the threaded hole
2
. The microphone is mounted on a stand
4
such that the threaded hole
2
of the microphone connection seat
1
is engaged with a threaded rod of the stand
4
. In view of the plug receptacle
3
being contiguous to the threaded hole
2
, the plug can not be inserted into the receptacle
3
after the microphone is mounted on the stand
4
. Now referring to
FIG. 2
, the microphone connection seat
1
of the prior art is shown comprising an extension rod
5
, which is provided at the top end thereof with a threaded projection
6
engageable with the threaded hole
2
of the microphone connection seat
1
, and is further provided at the bottom end thereof with a threaded hole
7
engageable with the threaded rod of the stand
4
. In view of the extension rod
5
, the stand
4
is prevented from interfering the plug, thereby enabling the plug to be inserted into the receptacle
3
of the microphone connection seat
1
.
Such a microphone connection seat
1
of the prior art as described above is defective in design in that the addition of the extension rod
5
results in an increase in the cost as well as the time that is required for mounting the microphone on the extension rod
5
, the deficiency of the microphone connection seat
1
may be overcome by increasing the distance between the threaded hole
2
and the receptacle
3
.However, an increase in the distance between the threaded hole
2
and the receptacle
3
results in an increase in volume of the microphone connection seat
1
. It is conceivable that a large microphone connection seat looks awkward.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a microphone connection seat which is free from the drawbacks of the microphone connection seats of the prior art described above.
It is another objective of the present invention to provide a microphone connection seat with a plug receptacle which can be swiveled and located.
In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by a microphone connection seat comprising a main body, a receptacle mount, and a receptacle body. The main body is provided with a threaded hole engageable with a microphone stand. The receptacle body is fastened with the receptacle mount such that the receptacle body can be swiveled and located, thereby preventing the plug form being interfered by the microphone stand.
