As shown in fig. 1 to 3, the invention discloses a rotationally controlled earphone, which includes a shell body 1, a middle frame 2, a circuit board 3, a mounting shell 5 and a second shell 7, wherein one end of the shell body 1 is arranged in an open manner, the shell of the earphone includes the shell body 1, the middle frame 2 and the second shell 7, the middle frame 2 is matched with the open end of the shell body 1, the middle frame 2 is provided with a sound outlet 21, the circuit board 3 is arranged between the middle frame 2 and the shell body 1, the circuit board 3 is provided with a hall sensor 4, the mounting shell 5 is rotationally matched on the middle frame 2, the mounting shell 5 is provided with a yielding hole 52 and an assembling groove 51, a magnet 6 is arranged in the assembling groove 51, the yielding hole 52 is arranged corresponding to the sound outlet 21, and the second shell 7 is buckled on the yielding hole 52 and connected with the middle frame 2; when the mounting case 5 drives the magnet 6 to rotate, the hall sensor 4 can detect the rotation angle of the magnet 6.

It can be understood that, in the actual use process, the control chip of the earphone configures the hall sensor 4 to be in the measurement mode, and at this time, the hall sensor 4 can monitor the magnetic field intensity in real time. When rotatory installation shell 5, magnet 6 also follows the rotation, and the magnetic field intensity of hall sensor 4 position also can follow the change, and hall sensor 4 can real-time detection magnetic field intensity, then passes to the circuit board 3 of earphone with the magnetic field intensity that detects. The control chip converts the magnetic field intensity value detected by the Hall sensor 4 into the corresponding rotating direction and rotating angle through operation, thereby realizing the measurement of the rotating angle and the rotating direction of the magnetic knob. When the rotation angle of the magnetic knob reaches a set threshold value, the control chip can make corresponding operations (volume increase/decrease, noise reduction depth adjustment, up-down curve switching and the like) according to condition judgment. That is to say, the earphone of this embodiment can realize increasing/reducing the volume, adjust and fall the depth of making an uproar, switch over regulating function such as song from top to bottom through rotatory magnetic knob, and it is very convenient to use.
