Abstract
The utility model discloses and belong to a kind of of daily living article there is the pendant device utilizing the whistle of people to look for object.Pendant device is made up of lanyard unit, outer cover unit and circuit unit.Wherein circuit unit comprises power circuit, sound collector, frequency matching circuit, hummer, LED lamp circuit.First the whistle sound of oneself is carried out Sound Match by frequency matching module by user, and then the scope of determining device receive frequency; Then when user looks for object, blow whistle, when the whistle frequency that device receives drops in this device receive frequency range, trigger hummer and to sound warnings, while LED send light warning, and then auxiliary user looks for object.The utility model simplicity of design is reasonable, convenient to use.
Description
Technical field
The utility model belongs to daily living article, is specifically related to a kind of pendant device with whistle positioning function.
Background technology
Because some people such as key, mobile phone, wallet commonly use the small volume of object, user often places it in somewhere conveniently and causes forgeing in daily life.In addition, also also exist because the reasons such as light is poor, shelter blocks cannot find the situation of article fast.For looking for the small articles such as key, mobile phone, wallet, people lose time, and affect mood, bring unnecessary trouble to daily life.For avoiding above-mentioned trouble, people usually hang some eye-catching jewelrys on the small articles such as key, mobile phone, wallet, but the method effect of this auxiliary searching object is not so good.Especially when object and jewelry are covered by other object or cover, or when dark, relying on eye-catching jewelry to find object, is infeasible substantially.In addition, although there is the auxiliary product looking for object such as key finder based on wireless communication principle, but this dependence wireless communication principle assists the method finding object to there is following deficiency: complex structure on the one hand, need to launch, receive two covering devices; There is electromagnetic radiation on the other hand, be unfavorable for carrying with for a long time.
Summary of the invention
The technical matters that the utility model solves there is provided one to be had and hangs on object, can judge the sound that people whistles, and sounds and report to the police and pendant device that light is reported to the police.
For realizing above-mentioned target, the utility model adopts following technical scheme:
There is a pendant device for whistle positioning function, comprise lanyard unit, outer cover unit and circuit unit.Lanyard unit comprises the metallic bond that the becket, the becket that combine small articles is in succession connected with said apparatus; Outer cover unit comprises the hummer loudspeaker of sounding outside housing main body that plastics make, housing main body, the luminant LED outside housing main body, the button for whistle frequency matching outside housing main body, the power switch button outside housing main body; Circuit unit comprises power circuit, sound collector, frequency matching circuit, hummer, LED lamp circuit, wherein power circuit comprises 3v button cell, Voltage stabilizing module and shift knob, 3v button cell is connected with Voltage stabilizing module with switch key successively, and Voltage stabilizing module is sound collector, frequency matching circuit, hummer, LED lamp circuit provide burning voltage; Frequency matching circuit comprises switching push button, frequency matching module, controls to prolong hummer and the out-of-work delay circuit of LED; LED lamp circuit comprises red LED lamp and a current-limiting resistance; Sound collector rate of connections match circuit, frequency matching module and delay circuit are connected with hummer, LED lamp circuit respectively.
Major function of the present utility model is:
A kind of pendant device with whistle positioning function is hung on firmware, to be covered by other object when object or cover, or dark is when being difficult to look for object, blow whistle, a kind of pendant device with whistle positioning function just can sound chimes of doom and light report to the police, help the person of looking for find required object fast.In addition, a kind of pendant device with whistle positioning function only identifies the sound frequency close with whistle voice frequency, avoids the interference of other sound frequency in daily life.
Compared with similar products comparatively, this product has the following advantages:
1. the utility model has the advantage that structure is simple, volume is little, lightweight, easy to carry;
2. the utility model uses simple, only needs to blow whistle and just can help to look for object according to the sound of reporting to the police and light;
3. the utility model only identifies the sound frequency close with whistle voice frequency, avoids the interference of other sound frequency in daily life;
4. the utility model assists compared to relying on wireless communication principle the method finding object, and radiation is low, is more conducive to user's health.
Accompanying drawing explanation
Fig. 1 is enforcement front view of the present utility model;
Fig. 2 is the utility model circuit diagram.
The implication that accompanying drawing 1 marks:
1 lanyard unit, 101 beckets, 102 metallic bonds, 2 outer cover units, 201LED lamp, 202 hummer loudspeaker, 203 frequency matching buttons, 204 power switch buttons.
Embodiment
Describe embodiment in detail by reference to the accompanying drawings.There is a pendant device for whistle positioning function, form primarily of lanyard unit, outer cover unit and circuit unit.
Lanyard unit comprises the becket connecting combination small articles, the metallic bond connecting said apparatus; Described outer cover unit is connected with lanyard unit; Described circuit unit is placed in outer cover unit, comprise power circuit, sound collector, frequency matching module and delay circuit, hummer, LED lamp circuit, wherein power circuit comprises 3V button cell, Voltage stabilizing module and shift knob, 3v button cell is connected with Voltage stabilizing module with shift knob successively, and Voltage stabilizing module is sound collector, frequency matching module and delay circuit, hummer, LED lamp circuit provide burning voltage; Frequency matching circuit comprises mode switch button, frequency matching module and time delay module, wherein the delay time of time delay module is set as 15 seconds, LE) circuit for lamp comprises red LED lamp and a current-limiting resistance, sound collector rate of connections match circuit, frequency matching circuit is connected with hummer, LED lamp circuit respectively; Described sound collector, frequency matching circuit, hummer, LED lamp circuit all adopt 3V DC-voltage supply.
Principle of work of the present utility model is: in the whistle frequency collection stage, mode switch button is switched to " setting " pattern, now, is sent the whistle tone signal of characteristic frequency by user; After described sound collector receives voice signal, the sound of collection is converted into electric signal, then frequency matching module is extracted, is analyzed and record the scope of main frequency information; In operational phase, mode switch button is switched to " use " pattern, when user looks for object, blow whistle, after described sound collector receives voice signal, the sound of collection is converted into electric signal, then frequency matching module extracts frequency information and carries out frequency matching, if frequency matching with the frequency range that prestores, frequency matching module triggers hummer and LED lamp circuit through time delay module, performs sounding alarm and the luminous alarm of 15 seconds.
What describe in above-described embodiment and instructions just illustrates principle of the present utility model, principal character and advantage; under the scope not departing from the utility model principle; the utility model also has various changes and modifications, and these changes and improvements all fall in the scope of the utility model protection.
