Embodiment
Below by specific embodiment, a kind of keyboard signal disposal system that configures high tone quality speech play described in the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of keyboard signal disposal system that configures high tone quality speech play, comprising:
Signal input connector 1, adopt FPC connector, be connected with touch signal treatment circuit 2, for touch signal is inputed to touch signal treatment circuit 2, its signal magnitude and sensitivity are determined by the capacitance of touch keyboard and the size of shunt capacitance, because of the capacitance difference of different touch keyboards, so shunt capacitance parameter is also different;
Touch signal treatment circuit 2, is comprised of integrated chip TS04 and its peripheral component (resistance, electric capacity), and it is connected with change-over circuit 3, and touch signal is converted to control signal.Keyboard in the electronic equipment that touch signal passage number is used by reality determines.TS04 directly exports low and high level signal.
Change-over circuit 3, its output terminal is connected with sound circuit 4 or microprocessor 5, for control signal being transferred to matrix keyboard signal or stand-alone keypad signal, (matrix keyboard signal controlling is enabled voice play function, stand-alone keypad signal controlling volume, the function such as stop, repeating), it is the conducting as switch gating matrix keyboard signal with triode, and be connected with LED light 6 as indication output signal, if while realizing multi-function by one key (i.e. an a plurality of output of input) control, only need organize identical change-over circuit 3 in the input end parallel connection of change-over circuit 3 more;
Common key-press signal input connector 7, adopts FPC connector, is connected, for the push button signalling of common keyboard is inputed to change-over circuit 3 with change-over circuit 3;
Sound circuit 4, adopt integrated chip NXD1004A, from the voice of the control signal of change-over circuit 3 inputs or the steering order control integration chip NXD1004A broadcasting storage inside of microprocessor 5 inputs, chip internal is integrated with power amplifier module can directly drive loudspeaker;
Microprocessor 5, for keyboard signal is converted to output order, and passes through Serial Peripheral Interface (SPI) (SPI) bus transfer to sound circuit 4, sound circuit 4 pronunciations, and output order comprises control volume, plays several inferior instructions.Meanwhile, exportable other control signals of microprocessor 5 (for example: binary control signal) next stage system is controlled, microprocessor 5 also can be connected with LED lamp 8, is used to indicate the output of other control signals.In actual use, if save this part, the MCU in available electron equipment transmits control signal to control sound circuit 4;
Principle of work of the present utility model is: signal input connector 1 inputs to touch signal in touch signal treatment circuit 2, the control signal input change-over circuit 3 (not needing through touch signal treatment circuit 2 if adopt common keyboard can signal be inputted to change-over circuit 3 by common key-press signal input connector 7) of touch signal treatment circuit 2 outputs, change-over circuit 3 is directly inputted sound circuit 4 or microprocessor 5 by keyboard signal, it is (bright while having output that connected LED light 6 will be indicated its output simultaneously, during no-output, go out), microprocessor 5 converts keyboard signal to steering order and inputs to that in sound circuit 4, (microprocessor 5 is exportable other control signals also, the control signal of LED lamp 8 indication outputs), sound circuit 4 receives after keyboard signal or steering order, play the voice of storage inside.
