Abstract
The utility model discloses a whistle with a timing apparatus and a luminous device. The whistle comprises a shell. A sound control timer is embedded in the shell. The sound control timer comprises a microphone and a power supply module. An output terminal of the microphone is connected with an input terminal of an amplifying and shaping circuit. The output terminal of the amplifying and shaping circuit is connected with an input terminal of a monostable trigger. A first output terminal of the monostable trigger is connected with the input terminal of a light emitting diode through a collector electrode of a triode. A second output terminal of the monostable trigger is connected with a first input terminal of a strobing gate circuit. A second input terminal of the strobing gate circuit is connected with the output terminal of a multivibrator. The output terminal of the strobing gate circuit is connected with the input terminal of a counter. The output terminal of the counter is connected with the input terminal of a decoder. The output terminal of the decoder is connected with the input terminal of a display screen. By using the whistle of the utility model, the whistle is sounded, and simultaneously timekeeping is started and light emitted so as to prompt an athlete so that an error caused by reaction time of a coach is avoided.
Description
Technical field
The utility model relates to a kind of whistle, particularly relates to a kind of whistle with time set and light-emitting device.
Background technology
in daily life study, whistle is the instrument of often using, for example when athletic training, the trainer blows whistle and sends instruction, in sports tournament, the judge also adopts whistle and instruction gun that the sportsman is illustrated usually, in the time of timing, the judge presses stopwatch usually when blowing whistle, because people's reflex action is different, reaction also has speed, the time of therefore adopting this mode to calculate is usually a little less than actual conditions, strict to time requirement in high level race, take the excessive games results that make of error of traditional approach inaccurate, simultaneously, in distance runway slightly far away, because the light velocity is faster than velocity of sound, therefore the sportsman is many sends the smog setting in motion according to instruction gun, because people's reaction is different, therefore can not guarantee that whistle and instruction gun work simultaneously, easily miscue is appearred in the sportsman.
The utility model content
Because the defects of prior art, technical problem to be solved in the utility model is to provide a kind of accurate timing and whistle that can be luminous when blowing whistle.
For achieving the above object, the utility model provides a kind of whistle with time set and light-emitting device, comprises housing, is embedded with the acoustic control timer on described housing; Described acoustic control timer comprises microphone and power module; The output terminal of described microphone connects the input end of amplification and rectification circuit, the output terminal of described amplification and rectification circuit connects the input end of monostalbe trigger, the first output terminal of described monostalbe trigger connects the base stage of NPN type triode, the grounded emitter of described NPN type triode, the input end of the collector connecting luminous diode of described NPN type triode, described light emitting diode are embedded on described housing; The second output terminal of described monostalbe trigger connects the first input end of gated circuit, the second input end of described gated circuit connects the output terminal of multivibrator, the input end of the output terminal linkage counter of described gated circuit, the output terminal of described counter connects the input end of code translator, the output terminal of described code translator connects the input end of display screen, and described power module is to described microphone, amplification and rectification circuit, monostalbe trigger, gated circuit, multivibrator, counter, code translator, display screen and light emitting diode power supply.
during use, blow whistle, after microphone receives voice signal, signal is amplified and Shape correction by amplification and rectification circuit, then signal is sent into monostalbe trigger and produced a broad-adjustable pulse signal, multivibrator produces continuous square wave as clock signal, the pulse signal that monostalbe trigger produces drives light emitting diode and sends light, simultaneously, the pulse signal that monostalbe trigger produces makes counter begin counting as gating signal, counter output signal is to code translator, code translator converts binary data decimal data to and sends to display screen to show data.
Better, described microphone is electret microphone, the electret microphone volume is little and cheap, can reduce costs.
Better, described power module is button cell, and the air cavity side opening of described housing is fluted, and described power module is stuck in described groove.
The beneficial effects of the utility model are: the utility model can begin timing and send light prompting sportsman when blowing whistle, avoided the error that caused in the reaction time by the trainer, improved efficient, it is small and exquisite that while the utility model also has structure, be easy to carry, advantage with low cost.
