Description of the invention: The technical field of the invention belongs to the invention. The invention relates to an electronic keyboard, in particular to a signal generated by cutting and conducting different telecommunication circuits in a key press, and calculating the playing time according to the celebration time. An electronic keyboard with a full button stroke for volume. [Prior Art] A general electronic keyboard is used to make a normal piano, such as the weight and size of the sound, and usually uses the speed at which the player plays the key as a basis for controlling the sound during circuit design. As shown in FIG. 1 and FIG. 2, the electronic keyboard 1 of the prior art comprises a housing u having a base 111 and a plurality of keys 12'. Each of the keys 12 is rotatably coupled to the rear end via a pivotal member 13 (1). The support base is mounted on the base (1) under the front end (playing end) of the key through a top element #15. A circuit board 16 electrically connected to a speaker (not shown) is disposed in front of the top member 15. The circuit board 16 is provided with a plurality of guiding members corresponding to the keys ,2 on the surface of the proximity key 12, each key The two-actuator 17 disposed at the front end of the 12 is disposed downwardly and forwardly, and corresponds to the connecting member 161 on the lower circuit board 16, respectively. When the key 12 is pressed, the contact member 17 will in turn interfere with the corresponding guide member 161 due to the difference in the degree of orientation, so that the telecommunication circuit (not shown) on the circuit board 16 is turned on and generates a signal. When the soft music is played, the time difference between the two touches 17 contacting the corresponding guides 161 is relatively large; on the contrary, the strong emotions will make the time difference between the corners 17 and the guides 161 shorter. By this, the size of the speaker volume is controlled. In other words, the longer the time difference, the smaller the volume of the 1259440 is played and the smaller the volume is, the shorter the time difference is. The hardware of the electronic musical instrument can easily distinguish the volume of the emitted sound from a volume of at least one hundred and eight steps, but is limited by the distance between the free end of the touched member η and the guiding member 161 (ie, the key 12) The pressing stroke) is usually only about 2 to 3 mm (the pressing stroke of the edge of the key 12 is about i2 mm, and the triggering member 17 and the guiding member 161 are generally disposed at an inner T distance from the edge of the key 12, so that the pressing stroke is less than 12 mm. In addition, after deducting the height of the touch member I? and the guide member 161, only about 2 to 3 faces are left in the remaining net stroke, and even if the slow pressing and the quick reduction of the key 12 are different, the gap between the materials is displayed. Still quite limited, it is difficult to accurately cut to hundreds of aliquots, and the resulting volume intensity will produce a significant step-like change in intensity, which is impossible to force = simulate a smooth change in the volume of the piano playing (ie, the car can not be produced in accordance with the human ear) The volume feels curve). In addition, since the stroke of the piano #12 (4) is short, the touch member 17 is in contact with the guide #161, and thus the touch of the piano 12 when the conventional piano is played cannot be expressed, so that the player who plays the piano is inevitably lost. 7 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an electronic keyboard that produces a volume level that is more responsive to human hearing. Another object of the present invention is to provide an electronic keyboard having a full keystroke that produces a key impact sensation. Therefore, the electronic keyboard with complete button stroke of the present invention is electrically connected to a sound source device, and can be sounded through the sound keyboard.

The first switch corresponds to a key, each first switch comprises a corresponding set of first touch members and a first conductive member, and one of the two is disposed on the housing below the key, wherein the other one is On the bottom surface of the rear end of the key, the first switch can be turned into a short-circuit state by the contact state of the first touch member and the first guide member when the corresponding key is moved from the unpressed position to the pressed position, and a first state is generated. Signal. The second switch corresponds to a key, each second switch comprises a corresponding set of second and second guides, and the two are correspondingly disposed on the key and the housing, and the second switch is corresponding to the key When the position is not moved to the pressing position, the short-circuit state of the second and second guiding members is turned into an on state, and a second signal is generated. The processing device is configured to receive the first signal and the second signal and calculate the two The time difference is used to control the size of the corresponding sound of the sound source device at different pressing speeds of the keys. The electronic keyboard with complete button stroke of the invention borrows the first switch and the second switch respectively to generate two signals, and the calculation of the time difference of the mouth to control the volume intensity, because the first switch is pressed to the bow The process of the early play has the largest press-scheduled 'thus, which can produce a better force 4,,, knife strength. In addition, the long press is strong and the weight is combined with the weight of the weight to make the key feel the impact of the key.

Referring to FIG. 8 and FIG. 9 , in the third preferred embodiment of FIG. 9 , after receiving the first and second signals, t 8 is then transmitted to the speaker according to the time difference and the pre-stored sound source corresponding to the key 3 . The electronic keyboard of the complete keystroke is also described by taking the electronic keyboard of the general electronic keyboard with the complete 1259440 electronic keyboard. The difference between this embodiment and the first embodiment and the second embodiment is the aspect and arrangement of the second switch 72. The following 6 statements are only made for this difference, and the rest of the same points can be referred to the description of the first embodiment and the second embodiment, and no more statements will be made. In this embodiment, the bottom plate 21 is further provided with a mount base 42 behind the key 3, and a circuit board 6 is connected above the rear end of the key 3, so that the rear end of the key 3 can be close to the circuit board 6 when pressed. . Each of the second switches 72 includes a second guiding member 722 disposed on the outer surface of the circuit board 6 adjacent to the key 3, and is located below the second guiding member 722 and is supported by an elastic member 723 (here) The second touch member 721 is mounted on the circuit board 6 for a rubber bowl 723). When the key 3 is in the unpressed position, the second touch member 721 and the second guide member 722 are separated into a short-circuit state, and the key 3 is When the unpressed position is moved to the pressing position, the rear end of the key 3 can be pressed to deform the rubber bowl 723, so that the second contact member 721 can be in contact with the second guiding member 722 to form a conductive state, and a second signal is generated. In this embodiment, the circuit board 6, the second driving member 7^, the second guiding member 7 2 2, and the elastic generating member 7 2 3 are disposed at the rear end of the key 3. In other embodiments, the members It can also be placed under the front end of the key 3 (see Fig. 1A). Since the actuation relationship and the result are the same, they will not be described. Moreover, the design pattern in which the second and second guide members 721 and 722 can be contacted and separated by the elastic member 723 can be replaced by other similar mechanisms, not limited to the above. In summary, the electronic keyboard 9 with the complete button stroke of the present invention utilizes the first signal 71 and the second signal generated by the first switch 71 and the second switch 72 between the on state and the short circuit state, and is processed by the first signal and the second signal.
