These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
Referring to fig. 1 to 4, the utility model provides a magnetic suspension damping microphone device, which includes a base 1 for placing on a work table and a wireless microphone 2 capable of suspending above the base 1, so as to greatly inhibit the vibration transmission between the wireless microphone 2 and the work table, and to facilitate the improvement of the sound quality of the wireless microphone 2 and the reduction of the working noise of the wireless microphone 2.
Optionally, a sound pickup is disposed inside the wireless microphone 2.
In this embodiment, the wireless microphone 2 is further provided with an upper magnet 202, an upper circuit board 203, a storage battery 204 electrically connected to the upper circuit board 203, and an induction coil 205 electrically connected to the upper circuit board 203.
The base 1 includes an upper case 101 having an opening facing downward and a bottom cover 102 for covering the opening of the upper case 101. The upper shell 101 is internally provided with a lower magnet 103 with the same polarity as the upper magnet 202 and a lifting assembly 104 connected with the lower magnet 103.
It can be understood that, in the non-operating state, the lifting assembly 104 drives the lower magnet 103 to move downward to the lower limit position, and at this time, the whole wireless microphone 2 is attached to the top of the base 1. In the working state, the lifting assembly 104 drives the lower magnet 103 to move upward to the upper limit position, and at this time, the repulsive force between the upper magnet 202 and the lower magnet 103 is enough to lift the whole wireless microphone 2, so that the wireless microphone 2 is suspended above the base 1. Therefore, the wireless microphone 2 does not directly contact with the working table, so that the vibration transmission between the wireless microphone 2 and the working table is effectively inhibited, the pickup tone quality and the broadcast tone quality are improved, and the noise caused by the vibration of the wireless microphone 2 on the working table can be reduced.
The middle position of the upper shell 101 protrudes upwards, an accommodating space 1011 is formed inside, a hall circuit board 105 is fixedly arranged in the accommodating space 1011, and a switch hall sensor 1051 and a magnetic control hall sensor 1052 are arranged on the hall circuit board 105.
The switch hall sensor 1051 is used for sensing the position distance of the upper magnet 202, when the magnetic field strength sensed by the switch hall sensor 1051 is too small, it indicates that the upper magnet 202 is too far away from the switch hall sensor 1051, and at this time, it should be that the user takes away the wireless microphone 2, and then the base 1 may enter a standby state, and further, before standby, the lower magnet 103 may be reset to a lower limit position. The wireless microphone 2 needs to be replaced on the upper case 101 before the next use.
Furthermore, a positioning bump 1012 is further fixedly arranged on the upper shell 101, a positioning groove 206 corresponding to the positioning bump 1012 is arranged at the bottom of the wireless microphone 2, and only when the positioning groove 206 is inserted into the positioning bump 1012, the standby state of the base 1 can be released, so as to avoid mistaken awakening.
The magnetically controlled hall sensor 1052 is used to sense changes in the magnetic field due to changes in the position of the upper magnet 202. A plurality of balance coils 106 are arranged in the base 1, and the balance coils 106 are used for generating an adjusting magnetic field for keeping the position of the wireless microphone 2 stable according to the sensing result of the magnetic control hall sensor 1052.
It can be understood that the upper magnet 202 and the lower magnet 103 are both permanent magnets, the repulsive force between the two is not adjustable, and it is difficult to keep the wireless microphone 2 stable during operation by simply relying on the lower magnet 103. After the magnetic control hall sensor 1052 is arranged, the magnetic control hall sensor 1052 can detect a magnetic field formed by the upper magnet 202 and the lower magnet 103 together, and when the magnetic field intensity detected by the magnetic control hall sensor 1052 is in a preset range, the upper magnet 202 and the lower magnet 103 are parallel to each other; when the magnetic field intensity detected by the magnetic hall sensor 1052 exceeds a preset range, it indicates that the upper magnet 202 is inclined, and then the balance coil 106 at the corresponding position can be controlled to operate according to the sensing result, so as to generate an adjusting magnetic field, and finally the upper magnet 202 is kept in a horizontal state.
It should be noted that the number of the balance coils 106 is at least three, and the three balance coils 106 are not arranged along the same straight direction, that is, the position connecting line of each balance coil 106 can form a plane. If all the balance coils 106 are arranged in the same straight direction, for example, from left to right, the magnetic fields generated by all the balance coils 106 are symmetrical in the front-rear direction, and if the upper magnet 202 is inclined in the front-rear direction, it is difficult to perform effective adjustment. Therefore, in the present embodiment, the arrangement position of each balance coil 106 can constitute a plane, so that the upper magnet 202 can be adjusted in four directions, i.e., front, rear, left, and right, in a horizontal plane.
In this embodiment, the number of the balance coils 106 is four, the four balance coils 106 are arranged in a square, and each balance coil 106 is located at one vertex angle of the square.

Optionally, the upper magnet 202 and the lower magnet 103 are both ring-shaped structures. Further, each of the balance coils 106 is located in the lower magnet 103, so as to improve the compactness of the base 1 and reduce the volume of the base 1.

The bottom of lifter plate 1041 is equipped with the internal thread hole, the border position of lifter plate 1041 is equipped with the slip breach, be equipped with in the base 1 and insert vertical guide arm 1013 in the slip breach. The rotating plate 1042 is positioned in the internal threaded hole and is in threaded connection with the internal threaded hole. The driving end of the driving motor 1043 is connected to the rotating plate 1042 and is configured to drive the rotating plate 1042 to rotate, so that the lifting plate 1041 moves up and down.
Specifically, when the driving motor 1043 drives the rotating plate 1042 to rotate forward, the vertical guide rods 1013 limit the rotating motion of the lifting plate 1041, and the lifting plate 1041 can only slide upward along the vertical guide rods 1013, so as to drive the lower magnet 103 to move upward; when the driving motor 1043 drives the rotating plate 1042 to rotate reversely, the vertical guide rods 1013 limit the rotation of the lifting plate 1041, and the lifting plate 1041 can only slide downwards along the vertical guide rods 1013, so as to drive the lower magnet 103 to move downwards.

secondly, the wireless microphone 2 is controlled to enter a suspension state through keys or voice, at the moment, the driving motor 1043 drives the lifting plate 1041 to drive the lower magnet 103 to move upwards, the wireless microphone 2 gradually rises under the action of repulsive force between the upper magnet 202 and the lower magnet 103 until the lower magnet 103 reaches an upper limit position, and the wireless microphone 2 is suspended above the base 1, so that recording or broadcasting can be carried out;
during the suspension:
if the wireless microphone 2 is taken away, the lifting plate 1041 automatically resets to the lower limit position, and then the base 1 enters a standby state;
if the magnetic control hall sensor 1052 senses that the upper magnet 202 deviates, the corresponding balance coil 106 is started to adjust, so that the wireless microphone 2 is always in a stable state;
