According to the keyboard 1 of the embodiment of the second aspect of the present invention, the keyboard 1 includes any one of the key structures 10, as shown in fig. 8, the keyboard 1 includes a plurality of key structures 10, and further includes a controller 11, an N row first-order scanning lead 111, an N row second-order scanning lead 112, and an M column vertical scanning lead 113 are led out from one end of the controller 11, where N and M are positive integers, specifically, the first-order scanning lead 111 is connected to each first circuit element 310, the second-order scanning lead 112 is connected to each second circuit element, the vertical scanning lead 113 is connected to each conducting assembly 400, the controller 11 of the keyboard 1 of the present solution is connected to the first circuit element 310, the second circuit element 320, and the conducting assembly 400 through each first-order scanning lead 111, the second-order scanning lead 112, and the vertical scanning lead 113, and by detecting the voltage values of the first circuit element 310, the second circuit element 320, and the conducting assembly 400, it is determined that the input signal is a first-order key signal or a second-order key signal, thereby realizing the first-order or second-order control of the keyboard 1, and enriching the input instruction of a single key.

It should be noted that the keyboard 1 may be used instead of a combination key when implementing a second-order input, and it is understood that the combination key is used as a combination of two conventional first-order keys, for example, ctrl + C, shift + = and the like, therefore, when implementing a second-order input, an input of a single key is equivalent to an input using a combination key, for example, an effect of Ctrl + C can be output when the key C is pressed again, at this time, it is implemented that a single key is used instead of a combination key, and at this time, the single key has two different input functions, and, when each key uses a second-order input, a combination of a plurality of second-order input key functions may be performed, for example, two keys are simultaneously pressed to implement a second-order input, at this time, it is equivalent to implementing two combination keys simultaneously operating, when each combination key is a 2-order combination, at this time, a combination input of 4-key non-conflict input may be implemented, it may be understood that a combination key of a second-order input may also be defined as more than 2-order combinations, for example, when each combination key is a combination of a Shift + X key, a number of a single key reaches at least a number of a first-order input that is increased by a conventional input control method, and thus, a conventional keyboard may implement a control method that at least one-order input by a conventional first-order input by at this time, and a conventional keyboard 1 input method, such as a conventional keyboard.

It should be noted that the keyboard 1 may be used together with a combination key when a single key realizes second-order input, and it can be understood that the combination key is used by combining two conventional first-order keys, for example, ctrl + C, shift + = and the like, so that when the keyboard 1 is used for second-order input and then is used together with a combination key, the same input effect can be achieved while reducing the number of keys pressed at a single time, and therefore, the number of functions of the keyboard 1 can be greatly increased on the premise of not increasing the total number of keys, and the input efficiency is greatly increased.

It should be noted that the second-order input instruction of a single key may be defined by the controller 11, and a specific second-order input instruction is given to each key, and a combination of the second-order input instructions may be customized, for example, the second-order input instruction of the key X may be defined as a function of implementing a Ctrl + X combination key, or a function of implementing a Shift + Ctrl + X combination key, it is understood that the definition of the second-order input instruction may be a function of at least one key, or a combination of two or more keys, and is not limited herein.

It can be seen that, when it is determined that the key mode of the keyboard 1 is the first-order key mode or the second-order key mode, the controller 11 of the keyboard 1 outputs a corresponding first-order or second-order key instruction, so as to perform instruction control on the electronic device connected to the keyboard 1, thereby completing the input and output operations of the keyboard 1 once.
