The keyboard includes a plurality of control keys and a blank key and the keyboard includes at least one control module arranged therein. The touchpad is directly arranged on the keyboard with one of control keys of the keyboard being converted into the touchpad. The touchpad is electrically connected to the control module. A relative position of the touchpad with respect to the blank key is such that the touchpad is located immediately leftward or rightward or both leftward and rightward of the blank key and the touchpad has a surface area that is smaller than or substantially equal to 2×2 cm2. Further, the touchpad has touch sensitivity and speed that are controlled by predetermined software. ## Claims ### Claim 1 A miniaturized touch keyboard structure, comprising: a keyboard, which comprises a plurality of control keys and a blank key, the keyboard comprising at least one control module arranged therein, the control module comprising a touch controller to correspond to a the touchpad for conducting a touch operation and to use a high signal-to-ratio (SNR) thereof to provide relatively high recognition speed and sensitivity for allowing the touchpad to achieve relatively high preciseness of touch operation within a limited area; and at least one touchpad, which is arranged in the keyboard and is electrically connected to the control module, the touchpad being located immediately rightward or leftward of the blank key or both rightward and leftward of the blank key, the touchpad having a surface area that is smaller than or substantially equal to 2×2 cm2. ### Claim 2 (depends on 1) The miniaturized touch keyboard structure according to claim 1, wherein the touchpad has a surface that is planar, convex curved, or recessed. ### Claim 3 (depends on 1) The miniaturized touch keyboard structure according to claim 1, wherein the touchpad has sensitivity and moving speed of a touch operation that are controlled by predetermined software. ### Claim 4 (depends on 1) The miniaturized touch keyboard structure according to claim 1, wherein the touchpad is formed of a Mylar material of PET polyester film or the touchpad has a surface that is formed of a Mylar material of PET polyester film ### Claim 5 (depends on 1) The miniaturized touch keyboard structure according to claim 1, wherein the control module comprises a wireless transmission unit and a power supply unit, the wireless transmission unit being electrically connected to the control keys, the blank key, and the touchpad, a signal from the control keys, the blank key, and the touchpad being transmitted wirelessly through the wireless transmission unit; and the power supply unit supplies electrical power to the control module. ### Claim 6 (depends on 5) The miniaturized touch keyboard structure according to claim 5, wherein the power supply unit is electrically connected to the wireless transmission unit and the touchpad to supply electrical power to the wireless transmission unit and the touchpad. ### Claim 7 (depends on 1) The miniaturized touch keyboard structure according to claim 1, wherein the keyboard is connectable, through wired transmission, to an electronic device. ### Claim 8 A miniaturized touch keyboard structure, comprising: a keyboard, which comprises a plurality of control keys and a blank key, the keyboard comprising at least one control module arranged therein, the control module comprising a touch controller; and at least one touchpad, which is arranged in the keyboard and is electrically connected to the control module, the touchpad being located immediately rightward or leftward of the blank key or both rightward and leftward of the blank key, the touchpad having a surface area that is smaller than or substantially equal to 2×2 cm2; wherein the touch controller is operable to conduct a touch operation with the touchpad and the touch controller provides a high signal-to-noise ratio (SNR) to achieve relatively high recognition speed and sensitivity for allowing the touchpad to achieve relatively high preciseness of touch operation within a limited area, so that the touchpad is matched with a high image quality display to allow the touchpad to precisely control a cursor displayed on the high image quality display. ### Claim 9 (depends on 8) The miniaturized touch keyboard structure according to claim 8, wherein the touchpad has a surface that is planar, convex curved, or recessed. ### Claim 10 (depends on 8) The miniaturized touch keyboard structure according to claim 8, wherein the touchpad has sensitivity and moving speed of a touch operation that are controlled by predetermined software. ### Claim 11 (depends on 8) The miniaturized touch keyboard structure according to claim 8, wherein the touchpad is formed of a Mylar material of PET polyester film or the touchpad has a surface that is formed of a Mylar material of PET polyester film ### Claim 12 (depends on 8) The miniaturized touch keyboard structure according to claim 8, wherein the control module comprises a wireless transmission unit and a power supply unit, the wireless transmission unit being electrically connected to the control keys, the blank key, and the touchpad, a signal from the control keys, the blank key, and the touchpad being transmitted wirelessly through the wireless transmission unit; and the power supply unit supplies electrical power to the control module. ### Claim 13 (depends on 12) The miniaturized touch keyboard structure according to claim 12, wherein the power supply unit is electrically connected to the wireless transmission unit and the touchpad to supply electrical power to the wireless transmission unit and the touchpad. ### Claim 14 (depends on 8) The miniaturized touch keyboard structure according to claim 8, wherein the keyboard is connectable, through wired transmission, to an electronic device.
