Abstract
The utility model discloses a ware is raced to be first to answer a question to pronunciation button, race to be the first to answer a question the button including a plurality of, race to be the first to answer a question a button termination power, the other end passes through grounding, each race to be the first to answer a question and press a key -type connection NAND gate, each all the other NAND gate inputs are connected respectively to the NAND gate output, a NOR gate input is connected to the NAND gate output, another input of NOR gate is connected pronunciation and is raced to be the first to answer a question the circuit, indicating device is raced to be the first to answer a question in the connection of NOR gate output. The utility model discloses a ware is raced to be first to answer a question to pronunciation button changes present button and races to be the first to answer a question the mode, races to be the first to answer a question through pronunciation and races to be the first to answer a question the simultaneous working with the button, can temper creative thinking well, and when once racing to be the first to answer a question when unsuccessful, it is not same individual possibly to be pronunciation and button simultaneously, and the person of racing to be the first to answer a question can continue to race to be the first to answer a question, can help to break fixed thoughtcast.
Description
Technical field
The utility model relates to a kind of question-and-answer game apparatus, and particularly a kind of voice button question-and-answer game apparatus, belongs to riddle equipment technical field.
Background technology
The central configuration of question-and-answer game apparatus is generally all made up of single-chip microcomputer and peripheral circuit, and accessory difference of its collocation is divided into again non-voice non-score question-and-answer game apparatus and voice to score question-and-answer game apparatus; Tradition question-and-answer game apparatus just probably judges to race to be the first to answer a question successfully or break the rules player's platform number, and what cannot demonstrate each player races to be the first to answer a question the time; Now question-and-answer game apparatus can illustrate accuracy, the fairness of ruling result by data; Make match considerably increase recreational while, also more fair, just; But its interesting deficiency of existing question-and-answer game apparatus, can not cultivate people well and break fixing thinking, be unfavorable for the creativity of cultivating participant.
Utility model content
(1) technical matters that will solve
For solving the problem, the utility model proposes a kind of voice button question-and-answer game apparatus, interesting foot, can temper participant's creative thinking well.
(2) technical scheme
Voice button question-and-answer game apparatus of the present utility model, comprises several and races to be the first to answer a question button, described in race to be the first to answer a question button one termination power, the other end passes through resistance eutral grounding; Race to be the first to answer a question button described in each and connect a Sheffer stroke gate, Sheffer stroke gate output terminal described in each connects all the other Sheffer stroke gate input ends respectively; Described Sheffer stroke gate output terminal connects a rejection gate input end; Another input end of described rejection gate connects voice and races to be the first to answer a question circuit; Described rejection gate output terminal connects races to be the first to answer a question indicating device.
Further, described voice are raced to be the first to answer a question circuit and are formed comparer by electret and amplifier and form; Described electret connects the in-phase end of amplifier by triode amplifier; The end of oppisite phase of described amplifier connects the reference voltage end of two electric resistance partial pressures.
Again further, described amplifier output terminal connects rejection gate input end.
Further, described triode amplifier is bias pressure formula total radio amplifier, and the base biasing resistor of institute's triode amplifier is adjustable resistance.
beneficial effect
Compared with prior art, voice button question-and-answer game apparatus of the present utility model, change existing button and race to be the first to answer a question pattern, race to be the first to answer a question to race to be the first to answer a question with button by voice and work simultaneously, creative thinking can be tempered well, simultaneously when once racing to be the first to answer a question unsuccessful, be likely pronunciation and button be not same person, the person of racing to be the first to answer a question can continue to race to be the first to answer a question, and can help to break fixing thoughtcast.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is that circuit theory diagrams raced to be the first to answer a question in voice of the present utility model.
Embodiment
Voice button question-and-answer game apparatus as depicted in figs. 1 and 2, comprises several and races to be the first to answer a question button K, described in race to be the first to answer a question button K mono-termination power, the other end is by resistance R ground connection; Race to be the first to answer a question button described in each and connect a Sheffer stroke gate B, Sheffer stroke gate B output terminal described in each connects all the other Sheffer stroke gate B input ends respectively; Described Sheffer stroke gate B output terminal connects a rejection gate C input end; Described another input end of rejection gate C connects voice and races to be the first to answer a question circuit A; Described rejection gate A output terminal connects races to be the first to answer a question indicating device L.
Described voice are raced to be the first to answer a question circuit A and are formed comparer by electret MIC1 and amplifier U1 and form; Described electret MIC1 connects the in-phase end of amplifier U1 by triode amplifier; The end of oppisite phase of described amplifier U1 connects the reference voltage end of two resistance R3, R4 dividing potential drops.
Described amplifier U1 output terminal connects rejection gate C input end.
Described triode amplifier is bias pressure formula total radio amplifier, and the base biasing resistor Rb1 of institute's triode amplifier is adjustable resistance.
Voice button question-and-answer game apparatus of the present utility model, when not racing to be the first to answer a question the soonest person's button and pressing, Sheffer stroke gate output low level, simultaneously, if voice are raced to be the first to answer a question circuit and are not raced to be the first to answer a question person the soonest, the same output low level of its output terminal, only have when pushing button the soonest and pronunciation is for same person the soonest, it can be raced to be the first to answer a question successfully, when push button the soonest and the soonest pronounce be not same person time, rejection gate output low level, does not race to be the first to answer a question successfully, then can continue to race to be the first to answer a question.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
