筒型ワイヤレスマイクロホン

Cylindrical wireless microphone

Abstract

【課題】電池装填室のカバーを兼ねたグリップが、電池装填室を開放したときベース部材から分離せず、迅速な電池交換が可能で、部品数の少ない筒型ワイヤレスマイクを得る。 【解決手段】一端側にマイクロホン本体1が結合され電池装填室3が設けられたベース部材2と、電池装填室3を開閉するカバーを兼ねた円筒状のグリップ6を備え、ベース部材2には電池装填室3よりも後方に雄ねじ5が、グリップ6の前端側には第1の雌ねじ7が、後端側には第2の雌ねじ8が形成され、第1の雌ねじ7が雄ねじ5に螺合されて雄ねじ5位置を通り越し、第2の雌ねじ8が雄ねじ5に螺合されてグリップ6が電池装填室3を閉塞し、雄ねじ5に対する第2の雌ねじ8の螺合が解除され、雄ねじ5と第1の雌ねじ7が干渉して、グリップ6が電池装填室3を開放した状態でグリップ6がベース部材2から分離することを防止する。 【選択図】図1
PROBLEM TO BE SOLVED: To provide a cylindrical wireless microphone with a small number of parts, of which a grip serving also as a cover of a battery loading chamber does not separate from a base member when the battery loading chamber is opened, and capable of quick battery exchange.SOLUTION: The cylindrical wireless microphone comprises: a base member 2 connected to a microphone body 1 on one end and having a battery loading chamber 3; and a cylindrical grip 6 serving also as a cover for opening/closing the battery loading chamber 3. A male screw 5 is formed behind the battery loading chamber 3 on the base member 2. A first female screw 7 is formed at the front end of the grip 6, and a second female screw 8 is formed at the rear end. The first female screw 7 is screwed onto the male screw 5 to pass over the position of the male screw 5, and the second female screw 8 is screwed onto the male screw 5 to close the battery loading chamber 3 with the grip 6. The male screw 5 and the second female screw 8 are unscrewed, and the male screw 5 and the first female screw 7 interfere with each other. Thus, the separation of the grip 6 from the base member 2 is prevented when the battery loading chamber 3 is opened by the grip 6.
