Telephone sound card information verification device

Abstract

The invention discloses a telephone sound card information verification device. The telephone sound card information verification device comprises a setter which is used for recording verification card information and a dialer which is used for receiving the verification card information recorded by the setter and sending verification card sound verification information sound. The dialer is provided with a storage unit, a control unit, a dual tone multiple signal frequency generator and a loudspeaker, wherein the storage unit stores the verification card information transmitted by the setter, the control unit reads and outputs the verification card information stored in the storage unit, dual tone multiple frequency signal generator receives the verification card information output by the control unit and generates dual tone multiple frequency signals, and the loudspeaker receives the dual tone multiple frequency signals and transforms the dual tone multiple frequency signals to sounds. By adding the dual tone multiple frequency signal generator and corresponding sound settings, tedious and repeated input of traditional telephone sound card information is avoided, relative information just needs to be input one time in advance, repeated input of the same information afterwards is avoided, and the trouble that all the information needs to be input again due to the fact that just one wrong information is input is also avoided.
