[0002] The walkie-talkie may be used in different environments. In a normal environment, the capacitive touch screen is easy to operate and sensitive to touch, but in harsh environments such as underwater, oil pollution or strong interference, the capacitive touch screen cannot be used; and Resistive touch screens are not afraid of oil, dust or strong interference, etc., so it is necessary to develop intercom devices that are compatible with capacitive touch screens and resistive touch screens

[0003] The inventors of the present application have discovered in long-term research and development that in order to realize dual touch in the prior art, the resistive touch screen and the capacitive touch screen are respectively placed on the front and back of the electronic device, and the two different touch screens are Touch operation, but because two screens are required for touch display, the thickness and cost of the product are increased, and the structure is complex and the integration level is poor; or the surface capacitive touch screen and the resistive touch screen are directly superimposed, through software To determine whether it is a capacitive touch or a resistive touch, apply a voltage to the second conductive layer in the composite touch panel. If the voltage detected by the first conductive layer is greater than the critical voltage, it is judged as a resistive touch, otherwise a capacitive touch is used. The control can judge whether there is contact and the contact position, but it cannot realize real multi-touch. The software algorithm is complicated, which increases the difficulty of judgment and is prone to errors. After a long time of use, resistive touch is prone to press offset problems.
