As shown in fig. 1, a casing 10 of the wireless sound box 1 is provided with an inductive input module 11. In the wireless sound box 1 shown in fig. 1, 2 and 7, one sensing input module 11 is provided. However, it will be understood by those skilled in the art that more sensing input modules 11 may be provided as the industrial design space of the housing 10 allows. Referring to fig. 3, the sensing input module 11 is mainly composed of a top cover 12, a sensing unit 14 and a substrate 15. Wherein the top cover 12 is preferably embedded in the housing 10 and flush with the outer surface of the housing 10, the top cover 12 being configured to carry touch input operations. The touch input operation may be generated by a hand of a user or may be generated by a stylus.

In this design, the pixel areas at other positions except the first pixel area ring maintain a standard uniform rectangular shape, and since the touch input operation guidance icon (as shown in fig. 2) is usually disposed at a relatively close center position and has a certain distance from the boundary, the standard uniform rectangular pixel area at the inner side can ensure accurate sampling detection of the touch input operation. During processing, preferably, a rectangular pixel area with 8 rows and 8 columns is used as a base, and a four-corner-removing circular layout design is performed to reduce the processing difficulty. In a scene in which a greater variety of touch input operations need to be detected, a greater number of pixel area rings may also be provided, or a greater number of pixel areas may be provided in each pixel area ring.
