Description

The voice answer-back time signal clock

The utility model relates to a kind of voice answer-back time signal clock, and this time signal clock is the electronic timekeeping clock that adopts speech recognition circuit.

The speaking clock of Chu Shouing in the market, it is the function that realizes speech chronopher by speech chronopher integrated circuit of a button control, this time signal clock needs user's action button, just can give the correct time, when this clock when using night, or the user can not find the putting position of this clock for the moment when being the blind person, just can't realize the function of its speech chronopher.

The purpose of this utility model is to propose a kind of voice answer-back time signal clock, and this time signal clock can be discerned user's voice command automatically by user's voice remote control, and provides the speech chronopher service according to its order.

The purpose of this utility model is achieved in that a kind of voice answer-back time signal clock, its recording keyboard is electrically connected with the keyboard input end of speech recognition circuit, two input ends of Sheffer stroke gate respectively with the WD4 of speech recognition circuit, WD3 is electrically connected, the output terminal of Sheffer stroke gate is electrically connected with d type flip flop 6 input end D, the input end of clock CLK of d type flip flop 6 is electrically connected with the EOR of speech recognition circuit end, the Q end of the input end of clock of d type flip flop 7 and d type flip flop 6 joins, the output Q end of d type flip flop 7 links to each other with microphone M by resistance R 2, this microphone is by capacitor C 1, resistance R 1 is electrically connected with the MIC end of speech recognition circuit, the input end of circuit of three-terminal voltage-stabilizing integrated is electrically connected with supply socket, its output terminal connects the vdd terminal of described sound circuit plate by stabilivolt WD, the output Q end of d type flip flop 6 is electrically connected with the trigger end T of sound circuit plate by resistance R 4, the described loudspeaker of its output termination.When using the utility model, press recording any one key (except the CL key) in the keyboard, aim at that microphone is said " what time? " then these voice are just as the voice typing speech recognition circuit that is identified, after, as long as microphone is asked " some? " when speech recognition is effective, WD4, WD3 are low level, or wherein an end is a low level, and then the output terminal of Sheffer stroke gate is a high level just, d type flip flop 6 will overturn, its Q end output high level, the speech chronopher circuit is triggered, and sends the voice that give the correct time.The utility model can be stored 10 voice for identification, and can change easily.

The utility model compared with the prior art, no matter have in the daytime or can both control its speech chronopher by sound night, advantage easy to use, especially to the blind person, handicapped the elderly, or the disabled person is more convenient.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1, electrical schematic diagram of the present utility model

Fig. 2, housing outside drawing of the present utility model

Referring to accompanying drawing, voice answer-back time signal clock of the present utility model has the recording keyboard 1 of one 11 key, this keyboard is electrically connected with the keyboard input end of speech recognition circuit 2, speech recognition circuit is selected the TC8860F integrated circuit for use, two input ends of Sheffer stroke gate 5 respectively with the WD4 of speech recognition circuit, WD3 is electrically connected, the output terminal of Sheffer stroke gate is electrically connected with d type flip flop 6 input end D, its effect is WD4 when speech recognition is invalid, WD3 is a high level, the output terminal of Sheffer stroke gate is a low level, like this during rising edge clock, d type flip flop 6 just can not overturn, its Q end keeps low level, the speech chronopher circuit can not be triggered, the input end of clock CLK of d type flip flop 6 is electrically connected with the EOR of speech recognition circuit end, when the EOR rising edge, be triggered, the input end of clock CLK of d type flip flop 7 and the Q of d type flip flop 6 end join, the output Q end of d type flip flop 7 links to each other with microphone M by resistance R 2, its effect is to turn-off microphone during speech chronopher, prevent that the sound that gives the correct time from producing interference to speech recognition circuit, cause the speech chronopher circuit by continuous trigger, d type flip flop 7 and d type flip flop 6 models are 4013, d type flip flop 7 is by peripheral cell capacitor C 5, resistance R 5, diode D1 constitutes monostable circuit, d type flip flop 6 is by peripheral cell capacitor C 3, resistance R 3 constitutes monostable circuit, microphone is selected the electret capacitor microphone for use, by capacitor C 1, resistance R 1 is electrically connected with the MIC end of speech recognition circuit, the input end of circuit of three-terminal voltage-stabilizing integrated 8 (model is 78L06) is electrically connected with 9 volts of supply sockets 3, its output terminal connects the vdd terminal of described sound circuit plate 4 by stabilivolt WD, the output Q end of d type flip flop 6 is electrically connected with the trigger end T of sound circuit plate by resistance R 4, the speaking clock chip that the described loudspeaker 9 of its output termination, sound circuit plate select for use China Shenzhen electricity day Electronics Co., Ltd. to produce.Can also add a standby power supply circuit that constitutes by diode D2, D3, D4, battery B in the circuit of the present utility model, the negative electrode of stabilivolt WD connects the negative electrode of D2, D3, the anode of WD connects the D4 negative electrode, and be electrically connected with the vdd terminal of sound circuit plate, the anode of D3, D4 connects anode, and the anode of D2 is electrically connected with the output terminal of circuit of three-terminal voltage-stabilizing integrated.Its effect is when external power has a power failure, and keeps the phonetic feature model of speech recognition and the sequential of clock not to lose.Foregoing circuit is installed in the housing 10 of plastics, and the top panel of this housing is installed loudspeaker, and front panel is installed button and microphone, and supply socket is installed in the side.
