DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microphone mounting device mainly used in a conference room or the like in which a microphone unit is mounted on the tip of a flexible support pipe, and more particularly, to a quick man-out type microphone. The present invention relates to a microphone mounting device that can be mounted on a screw mount type.

[0002]

2. Description of the Related Art For example, in an international conference hall or a lecture hall, a so-called gooseneck microphone using a flexible pipe is often used so that a microphone unit can be freely brought close to a speaker's mouth.

A gooseneck microphone of this kind is
A permanent installation that is integrally attached to a base such as a table is generally used, and the installation method is roughly classified into the following two methods.

The first method is called a quick mount method (or a connector mount method).
FIG. 5 is a cross-sectional view of the mounting portion. According to this method, an output male connector 13 is provided at the lower end of the support pipe 12 of the microphone 1. Although not shown for convenience of drawing, a microphone unit is attached to the upper end of the support pipe 12.

On the other hand, a base member 5 having a female connector 51 connectable to the terminal pins 14 of the male connector 13 is fixed to a base 9 such as a table with screws 52. The cable C for the microphone 1 is drawn from the female connector 51 to the back surface 92 side through an opening 91 provided in the base 9.

According to this method, by inserting the male connector 13 of the microphone 1 into the female connector 51 of the base member 5, the microphone 1 can be fixed to the base 9 such as a table by a so-called one-touch operation. it can. This is why it is called a quick mount.

Another method is called a screw mounting method, and FIG. 6 shows a main part of the mounting portion. In this method, a 5 / 8-inch 27-thread male screw 41, which is standard in the United States for mounting a microphone, is used as the microphone receiver 4.

The male screw 41 is first screwed into the opening 91 of the base 9, and is temporarily fixed so that the tip of the male screw 41 projects a predetermined length from the surface 93 of the base 9. And male screw 4
1 is securely fixed to the base 9 by screwing the fixing ring 42 from the back surface 92 side of the base 9 until it comes into contact with the back surface 92 of the base 9.

On the other hand, at the lower end of the support pipe 12 of the microphone 1, a flange 15 having substantially the same shape as the male screw 41 and a lock ring 16 which is prevented from falling off from the support pipe 12 by the flange 15. Provided. The lock ring 16 is formed with a female screw 16 a screwed with the male screw 41.

Accordingly, the microphone 1 is mounted on the base 9 by placing the lower end of the support pipe 12 on the male screw 41 and screwing the lock ring 16 to the male screw 41.
It is erected and fixed on top. In this screw mount system, an opening (not shown) for drawing out a cable is provided at a predetermined position of the support pipe 12, and the cable line of the microphone 1 is drawn out of the support pipe 12 through the opening.

[0011]

In the case of the screw mount system, since the support pipe 12 is connected to the male screw 41 via the lock ring 16 as described above, a microphone is attached to the lower end of the support pipe 12. It is difficult to incorporate a power module (electronic circuit) to be operated.

Therefore, the power module is installed at a position different from the microphone main body, and a connection is made between them by a cable, which requires a special microphone cable having a dedicated connector for the power module. The cost is higher than the quick mount method.

[0013] This is a disadvantage of the screw mount system, but as an advantage, the screw mount system can be operated with both a battery and a phantom power supply because a structure incorporating a battery is easily realized.

On the other hand, in the quick mount system, since an electronic circuit of the power module can be attached to the output male connector 13, a special microphone cable is not required as compared with the screw mount system. Although advantageous in cost, it is difficult to incorporate a battery, so that it can operate only with a phantom power supply alone.

[0015] Since which method is to be selected depends on the customer's choice, it is necessary for the manufacturer to prepare a quick mount method and a screw mount method.
There was a problem that it was troublesome in product management.

If the customer wants to change the currently used screw mount type to the quick mount type, the work must be started by removing the microphone receiver, which is a serious work. Will be.

By the way, at present, almost all devices such as a mixer that receives the output of a microphone are provided with a phantom power supply, so that even a battery which is cited as one of the advantages of the screw mount system can be operated. The advantage of gaining is becoming less relevant.

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional situation, and has as its object to provide a quick mount system even if a microphone receiver provided on a base such as a desk is a screw mount system. It is an object of the present invention to provide a microphone mounting device capable of mounting a microphone.
