Example 1

The microphone head in this embodiment is substantially the same as the microphone head described above, but the difference is that the structure of the buffer magnetic member group 101 is further described in this embodiment, specifically: because the first magnetic member 1011, the second magnetic member 1012 and the third magnetic member 1013 are disc-shaped, the first magnetic member 1011, the second magnetic member 1012 and the third magnetic member 1013 are all provided with 3 openings, the 3 openings are all at the edge of the disc and are equidistant, three fixing columns are arranged in the fixing frame 102, the three fixing columns are parallel to each other and sequentially penetrate through the 3 openings on each magnetic member, and the first magnetic member 1011, the second magnetic member 1012 and the third magnetic member 1013 can only move in the fixing columns.

By such a design, it can be avoided that the first magnetic member 1011, the second magnetic member 1012 and the third magnetic member 1013 are in a disc shape due to an excessively large distance therebetween, and are easily turned over in the fixing member 102 during the oscillation process, so that the first magnetic member 1011, the second magnetic member 1012 and the third magnetic member 1013 are repelled to be attracted.

Example 2

The microphone head in this embodiment is basically the same as the microphone head described above, but the difference is that the structure of the head fixing silicone frame 1032 is further described in this embodiment, specifically: the sound head fixing silica gel frame 1032 does not adopt a column-shaped design, but adopts a hourglass-bucket-shaped design, namely, the shape of the sound head fixing silica gel frame 1032 is wide at two ends and narrow in the middle, so that the wide parts at the two ends are respectively connected with the sound head fixing silica gel frame 1032 and the second magnetic part 1012, and the narrow part in the middle is positioned in the opening of the first magnetic part 1011.

With such a design, the probability of contact friction between the connecting member 1033 and the inner side of the opening of the first magnetic member 1011 can be reduced, so that the wear of the connecting member 1033 is reduced, and meanwhile, the friction generated sound during the vibration process is also reduced, which results in sound reception by the sound head 1031.
