Wherein the elastic wave sensor is in close contact with the inner wall of the touch area. The elastic wave sensor may be in the shape of an elongated strip, a ring, a circle, a square, or other shapes. The touch area may be provided on a handle housing of the headset.

When the touch area slides from a position with small roughness to a position with large roughness, the trend of the change of the energy value of each frequency band in the frequency spectrum is as follows: the change trend of the low-frequency band energy value is ascending, and the change trend of the high-frequency band energy value is descending.
As shown in fig. 2, the roughness of the touch area decreases from top to bottom. In other embodiments, the roughness of the touch area may also increase from top to bottom.
