The external knob is fixedly connected to the central shaft 21. Turning the external knob drives the central shaft 21 and the turntable 2 to rotate in turn.

[0040] When the user turns the external knob and the turntable 2 rotates to a certain angle, the spring 112 pushes the positioning post 111 into one of the limiting holes 212.

[0042] When the user wants to adjust the sound quality of the speaker more accurately, he turns the external knob, and the positioning post 111 disengages from the limiting hole 212 in the larger installation area, and the positioning post 111 pushes away the spring 112; the turntable 2 rotates a certain angle, so that the smaller installation area on the turntable 2 moves to the top of the positioning post 111, so that the limiting hole 212 in the installation area is locked by the positioning post 111; the external circuit board guides the current to the smaller inductor coil 3, so that the sound emitted by the speaker is more accurate; and, there are three inductor coils 3 of different sizes on the amorphous magnetic core inductor. When the user wants to adjust the sound of the speaker, he only needs to switch the connection between the three inductor coils 3 and the external circuit board to change the sound quality of the speaker and achieve multi-level adjustment.

[0043] The utility model provides an amorphous core inductor for car audio, wherein the positive pole and the negative pole of the base are electrically connected to the positive pole and the negative pole of the external circuit board. The user can rotate the central axis to drive the turntable to rotate, and one of the positive contacts approaches and contacts the positive pole, and one of the negative contacts approaches and contacts the negative pole, so that the current of the external circuit board is conducted to one of the inductor coils; when the user wants to enhance the breadth and fullness of the audio sound, the user rotates the central axis to conduct the inductor coil with a larger size to the external circuit board; when the user wants to enhance the accuracy of the audio sound, the user rotates the central axis to conduct the inductor coil with a smaller size to the external circuit board, thereby achieving the sound effect of adjusting the audio; because the sizes of the multiple inductor coils are successively reduced, the amorphous core inductor can achieve multi-level adjustment of the audio sound effect.
