Abstract
A conjoined key structure and an electronic device is described. The conjoined key structure includes a support frame with an accommodating groove, a first and second piezoelectric transducers fixedly accommodated in the accommodating groove and spaced from each other, pressure sensors fixedly accommodated in the accommodating groove and located between the first and second piezoelectric transducers, and a key covering the support frame and the accommodating groove. The key and the support frame are elastically connected. Two opposite sides of the first piezoelectric transducer respectively abut against the support frame and the key. Two opposite sides of the second piezoelectric transducer respectively abut against the support frame and the key. Two opposite sides of the pressure sensors respectively abut against the support frame and the key. The conjoined key structure can accurately determine touch actions of fingers, improving the recognition accuracy and consistency of the conjoined key structure.
