The invention discloses an EWR (Early-Warning Radar) control structure and a sound device. The EWR control structure comprises a EWR shell and a circuit board, wherein an EWR switch button, a volume reducing button and a volume increasing button are respectively arranged on different positions of the circuit board; a first pressing part corresponding to the EWR switch button, a second pressing part corresponding to the volume reducing button and a third pressing part corresponding to the volume increasing button are arranged on an inner wall of the EWR shell; when the EWR shell is pressed and deformed, the present pressing part, namely, the first pressing part/second pressing part/third pressing part is resisted against the corresponding button, so that the corresponding button operation is realized. According to the embodiment of the invention, three common buttons are arranged in the EWR shell; an upper cover and a lower cover of the EWR shell both have complete overall appearance structures; a user can operate the EWR switch and regulate the volume by pressing the corresponding position of the EWR shell; the inner structure is simple; the operation is easy; the production cost is lowered; the aesthetic degree of the overall structure is promoted; the use experience of the user is promoted.
