Description

【考案の詳細な説明】（産業上の利用分野）この考案は、スピーカの取付角度が任意の設定
しうるスピーカ取付装置に関する。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a speaker mounting device that allows the mounting angle of a speaker to be set arbitrarily.

（従来の技術）従来、スピーカの取付角度を調整した後、この
状態に固定するためにはネジなどを使用するのが
普通であつた。(Prior Art) Conventionally, after adjusting the mounting angle of a speaker, it has been common to use screws or the like to fix the speaker in this state.

になつている。 As shown in FIG. 1, the speaker mounting device includes a support rod 1 bent in an arc shape and having through holes 4 provided at regular intervals perpendicular to the central axis;
a coil spring 2 in a compressed state wound around the support rod 1; a ring-shaped member 3 whose front surface is formed with a corrugated uneven portion 5 pressed by the coil spring 2 fitted to the support rod 1; and a through-hole. A locking pin 6 is inserted into the locking pin 4 and engaged with the uneven portion 5, and a set screw 7 is screwed to the locking pin 6 from the opposite side. The speaker 8 is attached to the tip of an L-shaped member 15 fixed to the ring-shaped member 3 with a screw 9, and the lower end of the support rod 1 is attached to the base 10 with a screw 1.
It is installed in 1. As shown in FIG. 2, the through hole 4 is provided with a screw seat 12 having a larger diameter than the center at both ends, and the head 13 of the locking pin 6 and the body 14 of the set screw 7 are attached to the screw seat 12. are now engaged.

When compressed toward the base 10, the engagement with the locking pin 6 is released, and in this state, the insertion position of the locking pin 6 in the through hole 4 can be changed, or the coupling position with the uneven portion 5 can be changed. or change it. The locking pin 6 and the set screw 7 are always in elastic contact with the uneven portion 5 of the ring-shaped member 3 due to the restoring force of the coil spring 2, and are difficult to loosen due to vibrations of the car or the like.
