Except for a connection line between the circuit board 500 and the encoder 400, the closed space formed between the surface 600, the waterproof inner shell 130 and the bottom shell 110 is not in contact with the outside, thus reducing the entry of external air moisture and increasing the waterproof performance of the electronic device.
