  FIG. 2 shows the microphone shown in FIG. 7 in Patent Document 1 again. The microphone 1 has a flexible support pipe 3 having a slim appearance with a microphone unit 2 attached to the tip side thereof. And a power module section (not shown) installed in another place that is not conspicuous.

  In this case, the microphone 1 is installed on a podium using, for example, a microphone mounting unit shown in FIG. That is, in the microphone 1, the receiving screw 6 with a male screw is protruded toward the surface 52 side with respect to the through hole 54 provided in advance in the base 51 including a top board such as a podium or a desk. The position is fixed by tightening and screwing a fixing nut 7 with a washer 8 interposed in the other end portion 6b protruding through the back surface 53 side of the base 51. Next, after a washer 9 is interposed in one end portion 6a of the receiver 6, the support pipe 3 of the microphone 1 is fastened and screwed to the lock ring 5 that holds the base end flange portion 4 provided in the base end portion 3a. Thereby, the position of the microphone 1 is fixed on the base 51.

  That is, in the case of the microphone mounting unit shown in FIG. 3, the microphone 1 is supported by the support pipe 3 by tightening the fixing nut 7 and the lock ring 5 to the receiving member 6 disposed on the base 51. Thus, the position can be fixed to the base 51 side.

  However, in the case of the microphone mounting unit shown in FIG. 3, repeated tightening and shock are applied to the base 51 side, so that the tightly screwed state of the lock ring 5 and the fixing nut 7 to the holder 6 can be maintained. There was a problem that the microphone 1 gradually became loose and the microphone 1 side wobbled.

  Further, since the support pipe 3 of the microphone 1 is directly connected to the base 51 side via the support 6, vibration noise transmitted from the base 51 side is easily propagated to the microphone 1 side via the support pipe 3. There was also a bug that would end up.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems encountered in conventional microphone mounting units, and it is an object of the present invention to provide a microphone mounting unit that can securely mount a microphone to a base side with a shock mount effect. And

  The present invention has been made to achieve the above-mentioned object, and is a cylindrical holder with a male screw that is loosely arranged by projecting an upper end and a lower end of a through hole provided in a base, A small-diameter ring portion interposed between the cylindrical holder and the through hole is provided on the lower surface side, and a built-in nut screwed with the upper end portion is held and elastically arranged on the upper end portion side.

  According to the present invention, the fixing nut is tightened and screwed to the cylindrical holder side via the lower rubber ring, and the lock ring is screwed to the cylindrical holder side via the upper rubber ring with friction. As a result, even if vibrations or impacts are repeatedly applied to the base side, the respective tightening screwing states can be stably maintained without loosening.

  Further, since the support pipe in the microphone can be fixed to the base side via a cylindrical holder in which an upper rubber ring and a lower rubber ring are interposed between the base rubber and the base, Vibration noise that tends to be transmitted from the base side can be effectively reduced by the shock mount effect produced by the lower rubber ring.

  FIG. 1 is an explanatory view showing an attachment state of an example of the present invention by enlarging a main part. According to FIG. 2, the mounting unit 11 of the microphone 1 shown in FIG. 2 includes a cylindrical holder 12 with a male screw 13, an upper rubber ring 22 elastically arranged on the upper end portion 14 of the cylindrical holder 12, and a cylinder. A lower rubber ring 32 elastically arranged on the lower end 15 of the support 12, a fixing nut 42 screwed to the lower end 15 of the cylindrical receiver 12, and a screw on the upper end 14 of the cylindrical support 12. The lock ring 52 arranged together constitutes the whole.

  Among these, the cylindrical holder 12 with the external thread 13 engraved on the outer peripheral surface thereof has an upper end portion 14 and a lower end portion 15 through a through hole 64 provided in advance in a base 61 including a top plate such as a podium or a desk. Is formed so that it can be loosely inserted into the through hole 64 with a length that protrudes from the outer periphery and an outer diameter that is smaller than the inner diameter of the through hole 64.

  The upper rubber ring 22 has, on the lower surface 23 side, a small-diameter ring portion 24 disposed with elasticity in a gap 18 formed between the outer peripheral surface of the cylindrical holder 12 and the inner peripheral surface of the through hole 64. And it is formed so that the built-in nut 25 screwed with the upper end part 14 of the cylindrical holder 12 can be held and elastically arranged on the upper end part 14.

  The lower rubber ring 32 has, on the upper surface 33 side, a small-diameter ring portion 34 that is disposed in contact with the gap 18 formed between the outer peripheral surface of the cylindrical holder 12 and the inner peripheral surface of the through hole 64 with elasticity. And has a built-in washer 35 inserted into the lower end 15 of the cylindrical holder 12 so as to be elastically arranged on the lower end 15.

  The fixing nut 42 is formed so as to be screwed to the lower end portion 15 of the cylindrical holder 12 with the lower rubber ring 32 and the washer 43 interposed therebetween.

  The lock ring 52 is formed so as to hold the proximal end flange portion 4 of the support pipe 3 in the microphone 1 and to be screwed to the upper end portion 14 of the cylindrical holder 12 with the upper rubber ring 22 interposed. .

  More specifically, as shown in FIG. 2, the microphone 1 has a slim appearance and has a microphone unit 2 attached to the distal end side of a support pipe 3 that is formed flexibly, and the proximal end side in FIG. As shown, the base end flange portion 4 provided with an outer diameter substantially matching the outer diameter of the cylindrical holder 22 is formed.

  The lock ring 52 includes a top plate portion 52 having a circular hole 53 having a diameter that allows insertion of the base end portion 3a of the support pipe 3 at the center position, and a peripheral wall portion 54 capable of accommodating the base end flange portion 4. Are formed in a cylindrical shape having a substantially U-shaped cross section, and a female screw 55 that is screwed into the male screw 13 of the cylindrical holder 12 is cut into the inner peripheral surface of the peripheral wall portion 54.

  Next, the operation and effect of the present invention having the above configuration will be described. A lock ring 52 is provided in advance on the proximal end flange portion 4 of the support pipe 3 in the microphone 1.

  Further, the lower rubber ring 32 is fed into the lower end portion 15 of the cylindrical holder 12, and a fixing nut 42 is screwed on with a washer 43 interposed.

  The cylindrical holder 12 to which the fixing nut 42 is screwed is loosely inserted into the through hole 64 of the base 61 from the back surface 63 side, and the upper end portion 14 thereof is protruded to the front surface 62 side. At this time, the small-diameter ring portion 34 of the lower rubber ring 32 is disposed with elasticity in the gap 18 formed between the outer peripheral surface of the cylindrical holder 12 and the inner peripheral surface of the through hole 64, and is cylindrical. The support 12 is also temporarily fixed without falling off.

  Next, the upper rubber ring 22 is screwed through the built-in nut 25 to the upper end portion 14 of the cylindrical holder 12 protruding on the surface 62 of the base 61. At this time, the small-diameter ring portion 24 of the upper rubber ring 22 is disposed with elasticity in a gap 18 formed between the outer peripheral surface of the cylindrical holder 12 and the inner peripheral surface of the through hole 64. become.

  After the cylindrical holder 12 is disposed on the base 61, the fixing nut 42 is further tightened so that the lower end 15 side of the cylindrical holder 12 is interposed via the upper rubber ring 22 having the small diameter ring portion 24. The cylindrical holder 12 can be fixed in position while being elastically contacted to the side.

  At this time, the fixing nut 42 can maintain its screwed state without being loosened by the frictional force generated when it is pressed against the upper rubber ring 22, so that it may be repeatedly vibrated or shocked on the base 61 side. Even if it is added, the tightened screwed state can be stably maintained without loosening.

  After the cylindrical holder 12 is disposed on the base 61, the microphone cord C with the dedicated connector J included in the microphone 1 is fed into the cylindrical holder 12 from above and pulled out below the back surface 63 of the base 61.

  After the microphone cord C with the dedicated connector J is pulled out from the cylindrical holder 12, the microphone is placed on the protruding end side of the upper end portion 14 of the cylindrical holder 12 to which the upper rubber ring 22 side is screwed via the built-in nut 25. The lock ring 52 in a state of holding the proximal end flange portion 4 is tightened and screwed.

  At this time, the corresponding portion of the upper rubber ring 22 that comes into pressure contact when the lock ring 52 is tightened is pushed into the lock ring 52 and elastically deformed to form the recessed portion 26.

  That is, the tightened lock ring 52 is securely screwed in without loosening due to the frictional force generated by the recessed portion 26 of the upper rubber ring 22 while securely holding the proximal end flange portion 4 of the support pipe 3 in the microphone 1. Since the state can be maintained, even if a vibration or impact is repeatedly applied to the base 61 side, the tightening screwing state can be stably maintained without loosening.

  Therefore, the support pipe 3 in the microphone 1 is a cylindrical holder in which an upper rubber ring 22 having a small diameter ring portion 24 and a lower rubber ring 32 having a small diameter ring portion 34 are interposed between the support pipe 3 and the base 61. 12, the position can be fixed to the base 61 side.

  Therefore, the microphone 1 including the microphone unit 2 generates vibration noise that tends to be transmitted from the base 61 side via the support pipe 3 due to the shock mount effect produced by the interposed upper rubber ring 22 and lower rubber ring 32. The position can be fixed to the base 61 while being effectively reduced.
