A mouse using sound frequency transmission is disclosed. By pressing a key or rolling a wheel in the mouse, a plurality of sound-sending elements with different sound frequencies is knocked to produce a plurality of sound frequency signals. These sound frequency signals are received and transformed by a receiver connected with a computer. Therefore, the moving signals produced by the mouse are able to be transferred to the computer to achieve the purpose of controlling the cursor in the computer or executing computer functions. Therefore, the inconvenience of using batteries to supply power in a conventional mouse can be improved.
