The invention provides an audio control device for VTM equipment, and the device is characterized in that the device comprises a power supply, a control unit, a power amplification unit, a first integrated interface processing unit, a second integrated interface processing unit, a microphone, and a reset switch. The control unit is connected with the power amplification unit, the first integrated interface processing unit, the second integrated interface processing unit, the microphone, and the reset switch. The first integrated interface processing unit is also connected with external computer equipment. The first integrated interface processing unit is used for transmitting a switching control instruction between the control unit and computer equipment, and transmitting audio signals corresponding to the second integrated interface processing unit and the microphone. The second integrated interface processing unit is used for collecting or playing the audio signals, and carrying out the switching between the collection of the audio signals and the playing of the audio signals according to a received pressure signal. The device can effectively achieve the control of the audio signals of VTM equipment.
