When the audio signal is collected, the head of the subject is rested on a pillow formed by the pillow-shaped blocks 9, a part of the pillow-shaped blocks 9 contacted with the head of the subject is subjected to pressure given by the head, the height of the part of the pillow-shaped blocks 9 is lowered under the action of the pressure, the height of a connecting rod 305 connected with the part of the pillow-shaped blocks 9 is synchronously lowered, the connecting rod 305 is lowered to drive a part of the connecting rope 8 to be lowered, the connecting rope 8 is changed into a bent V shape from a straight line state, the lowest point of the V shape is positioned under the head, at the moment, the balancing weight 7 slides to the lowest point of the V shape along the connecting rope 8 under the action of gravity, and the balancing weight 7 drives the microphone 602 to move above the head of the subject through the mounting block 5 in the sliding process.

That is, through the above structure, when the head of the subject moves on the pillow, the microphone 602 can also move along with the head of the subject, so as to ensure that the distance between the microphone 602 and the head of the subject is kept constant, so as to reduce the fluctuation of the audio signal caused by the change of the sleeping gesture, and the audio signal collected by the microphone 602 is sent to the sleep monitoring instrument through the wireless signal.

the pillow 9 contacting with the head of the subject descends, and the first compression spring 304 and the second spring 901 are compressed simultaneously in the descending process, the pillow 9 descends to drive the first guide rod 302 to descend, and the first guide rod 302 drives the connecting rod 305, so that the connecting rod 305 drives the connecting rope 8 to descend.

Example 3

As shown in fig. 5 to 9, the rotating structure comprises a magnetic block 6, the magnetic block 6 is rotatably mounted on the mounting block 5, a bracket 601 is fixedly connected on the magnetic block 6, and a microphone 602 is mounted on the bracket 601. The pillow-shaped block 9 is provided with an air bag 902, the base 1 is fixedly connected with a guide pipe 904, the guide pipes 904 are in one-to-one correspondence with the pillow-shaped block 9, a permanent magnet 905 is slidably matched in the guide pipe 904, the air bag 902 is connected with the guide pipe 904 through a hose 903, and the magnetic block 6 and the permanent magnet 905 generate repulsive magnetic force.

The neck support part is arranged on the higher side of the pillow-shaped block 9, and can support the neck when the subject sleeps so as to improve the sleeping comfort of the subject, and the air bag 902 is arranged on the neck support part.

When the neck of the subject applies pressure to the bladder 902, the bladder 902 is forced to increase the pressure inside the guide tube 904, which increases the pressure inside the guide tube 904 to move up with the permanent magnet 905, close to the magnetic block 6.

When the subject lies down, as shown in fig. 11, the center line of the neck, the center line of the head and the center line of the microphone 602 are coincident, the compressed air bags 902 are uniformly distributed on both sides of the microphone 602, the permanent magnets 905 on both sides of the microphone 602 are lifted, and the magnetic forces on both sides of the magnetic block 6 are balanced although they are increased, so that the magnetic block 6 will not rotate at this time.

When the subject lies on his side, as shown in fig. 12, the center line of the head and the center line of the microphone 602 coincide, but the center line of the neck is shifted, at this time, the air bag 902 pressed by the neck is located at only one side of the microphone 602, the permanent magnet 905 corresponding to the pressed air bag 902 will move upward under the pressure, increasing the repulsive force to the magnetic block 6, and the increased repulsive force is located at only one side of the magnetic block 6, but the repulsive force at the other side of the magnetic block 6 will not change, at this time, the equilibrium state of the magnetic block 6 will be broken, the magnetic block 6 will rotate under the repulsive force, and because the increased repulsive force is located at the side of the neck, the magnetic block 6 rotates to drive the microphone 602 to deflect toward the side of the face, so as to ensure the distance between the microphone 602 and the mouth and nose, thereby ensuring the stability of audio acquisition.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
