Abstract
The utility model relates to a noise detection prompting apparatus. In public places we can often see caution boards with some characters or signs for silently prompting people to follow the public order, for example: no smoking, please keep health, please keep quiet, etc. The passive slogan prompts sometimes can only play a propaganda effect without playing supervising and prevention effects. In the utility model, the noise detection prompting apparatus includes a pickup (1); the pickup is connected with an integrated chip (2); the integrated chip is connected with a loudspeaker (3); and the integrated chip is respectively connected with a total switch (4), a recording switch (5) and an adjusting turn button (6). The noise detection prompting apparatus provided in the utility model is used for prompting people for too high noise in the public places.
Description
Technical field:
the utility model relates to a kind of noise measuring alarm set.
Background technology:
We see
through regular meeting in public places, and the warning sign of some literal or sign is quietly people that reminding observe public order, as no smoking, please keep health, quiet please or the like.The prompting of the poster property of these passive types can only be played tendentious effect sometimes, the effect that can not play supervision and prevent.
Summary of the invention:
The purpose of
the utility model is that the problem that is directed against above-mentioned existence provides a kind of noise measuring alarm set; Sound size that can intellectual monitoring environment of living in; When reach certain branch the time, then trigger the good prompting language of sound circuit played pre-recorded.This device is used in the environment of no supervision, or the environment that makes a racket is prevented in owner's inconvenience.
Above-mentioned purpose realizes through following technical scheme:
noise measuring alarm set, its composition comprises: acoustic pickup, described acoustic pickup connects integrated chip, and described integrated chip connects loudspeaker, and described integrated chip connects master switch, recording switch and adjusting knob respectively.
Beneficial effect:
sound size that 1. the utility model can intellectual monitoring environment of living in, when reach certain branch the time, then trigger the good prompting language of sound circuit played pre-recorded.This device is used in the environment of no supervision, or the environment that makes a racket is prevented in owner's inconvenience.Share the environment such as public visiting hours, waiting room, room for individual study in ward like the many people of hospital.When this installs the predetermined decibel of residing ambient sound general goal, play the voice suggestion people that pre-record, this device volume is little; Can fixedly put, also can carry temporarily, this device becomes digital signal to the analog signal conversion of natural-sounding; Adopt the semiconductor integrated chip as storage unit, this device can be according to actual needs, convenient, flexible records 20 seconds voice; This device is simple to operate; The knob of a master switch, a recording switch and a monitoring of environmental sound size only is set, and this device can also be recorded some advertising slogans or notice language, when the people sends sound of movement nearby, then plays.
2. the automatic acquisition environment sound of this device size whether in allowed limits, the critical value of the sound of environment is adjustable.
Noise identification and prerecording voice double-tone passage is frequently adopted in
3. the utility model, makes the stability of circuit better.
are the ISD1820P digital speech storage chip of the up-to-date production of the utility model employing American I SD company 4.; Single hop voice recording 8-20 second, the endless track sound recording that surpasses 10000 times, and not power consumption information stores 100 years; Be equipped with the supply voltage accommodation of 3V-5V broad; Volume is little, can fixedly put, and also can carry temporarily.
Description of drawings:
accompanying drawing 1 is the structural representation of the utility model.
accompanying drawing 2 is circuit theory diagrams of the utility model.
Embodiment:
Embodiment 1:
are shown in accompanying drawing 1: the noise measuring alarm set; Its composition comprises: acoustic pickup 1; Described acoustic pickup connects integrated chip 2, and described integrated chip connects loudspeaker 3, and described integrated chip connects master switch 4, recording switch 5 and adjusting knob 6 respectively.
Principle of work:
shown in accompanying drawing 2, the utility model is a core with pickup transmitter BM1, RP1 and VT1, has formed the sound signal collecting circuit, and RP1 is used to regulate the critical value of sounds trigger, promptly sends the noise level of phonetic warning; VT2 and C3 give the base stage of switch triode VT3 and do logic determines after the signal of gathering is carried out amplification filtering; 2 pins of IC are the trigger end of voice storage integrated chip, and not playback when 2 pins obtain low level is to trigger sound circuit to play the voice of pre-recording when 2 pins obtain high level; Speech chip 4,5 pins connect recording microphone, and 1 pin is a record button, and 13 pins are record indicator.7,9 pins are the speech play loudspeaker.S2 is a coupled switch, and the collector of people R3 and VT3 is communicated with during normality, and IC integrated circuit 1 pin and Vcc break off, and the collector c of R3 and VT3 breaks off when pressing S2, and IC integrated circuit 1 pin and Vc connect.
Claims (1)
1. noise measuring alarm set, its composition comprises: acoustic pickup is characterized in that: described acoustic pickup connects integrated chip, and described integrated chip connects loudspeaker, and described integrated chip connects master switch, recording switch and adjusting knob respectively.
