Abstract
The utility model provide a kind of show decibel from tuning square dance playing device, the volume situation that decibel instrument detects surrounding environment is set, and by CPU audio amplifier played sound and controls, to reach the effect of the volume controlling audio amplifier, thus avoid volume too sound disturb residents.Meanwhile, the different buttons comprised in action button unit also make operation more convenient, avoid light bad time the single display screen playing device inconvenience that brings.
Description
Technical field
The utility model belongs to service for life field, be specifically related to a kind of show decibel from tuning square dance playing device.
Background technology
Along with the raising of living standards of the people, pensioner the old men still health are good for bright, hale and hearty, the movable welcome obtaining everybody of square dance, but a lot of squares dance decibel when broadcasting is excessive, becomes noise, has a strong impact on the living environment of nearby residents.
The square dance playing device function of current most of market sale is simple, because the difference of melody audio frequency when making, the melody had during music can be very loud suddenly, and some melodies are relatively lighter again, needs often to start to regulate volume, very inconvenient.In addition, it is not too convenient that current square dance playing device uses when playing and specifying melody, particularly when looking for song, needing next song or upper one bent more than, ground to press and going for song.
In addition, aunts, when dancing square, although jump almost every day, wish that again some changes, and wish that dance music layout can be abundanter.General playing device can only by using multiple u dish to solve simultaneously, frequent dancing inserts a u dish for a moment, operate cumbersome, and due to general light when dancing square be not very good, in the market single display screen playing device can not satisfy the demand.
In view of the foregoing, the utility model provide a kind of show decibel from tuning square dance playing device.
Utility model content
The utility model provide a kind of show decibel from tuning square dance playing device, comprise storage card, USB interface, touch-screen, decibel instrument, audio amplifier, power supply, action button unit and CPU, described storage card, USB interface, touch-screen, decibel instrument, audio amplifier, power supply and action button unit connect described CPU respectively.
Preferably, described USB interface is 2.
Preferably, described CPU is made by embedded chip.
Preferably, described action button unit comprises shift knob, volume adjustment knob, played in order button, shuffle button, order of songs designated button, list of songs button, digital button and OK button.
The display decibel provided by the utility model from tuning square dance playing device, be provided with the volume situation that decibel instrument detects surrounding environment, and by CPU audio amplifier played sound and controls, to reach the effect of the volume controlling audio amplifier, thus avoid volume too sound disturb residents.Meanwhile, the different buttons comprised in action button unit also make operation more convenient, avoid light bad time the single display screen playing device inconvenience that brings.

Embodiment
Hereinafter also describe the utility model in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Fig. 1 be the display decibel that provides of the utility model preferred embodiment from tuning square dance playing device internal structure schematic diagram.As shown in Figure 1, the playing device of waving from tuning square of the display decibel that the utility model preferred embodiment provides comprises storage card 1, USB interface 2, touch-screen 3, decibel instrument 4, audio amplifier 5, power supply 6, action button unit 7 and CPU 8, and described storage card 1, USB interface 2, touch-screen 3, decibel instrument 4, audio amplifier 5, power supply 6 and action button unit 7 connect described CPU 8 respectively.Wherein, described CPU 8 is made by embedded chip.In the present embodiment, described storage card 1 is SD storage card, and touch-screen 3 is touching liquid-crystal display screen.Wherein, described decibel instrument 4 is for gathering environment decibels reportedly to CPU.
Fig. 2 be the display decibel that provides of the utility model preferred embodiment from tuning square dance playing device overall schematic.Fig. 3 be the display decibel that provides of the utility model preferred embodiment from tuning square dance playing device panel schematic diagram.As shown in Figure 3, in the present embodiment, USB interface comprises 11 and 12 totally 2, for accessing USB flash disk.
With reference to Fig. 3, action button unit comprises volume adjustment knob 9, shift knob 10, played in order button, shuffle button 13, order of songs designated button 14, list of songs button 15, digital button and OK button 16.Wherein, order of songs designated button 14 comprises First button, last first button, a rear first button and last first button 4 buttons.In the present embodiment, list of songs button 15 comprises 4 buttons corresponding playlist 1, playlist 2, playlist 3 and playlist 4 pre-seted respectively.In addition, digital button and OK button 16, press the song that OK key plays appointment numbering after pressing song number.
In figure 3, the song list that touch LCD screen displaying contents comprises current environment decibels and plays at present, the operation that touching liquid-crystal display screen can complete comprises: play decibel and arrange, playlist is browsed, playlist is arranged, and imports USB flash disk song to built-in SD storage card.When reality uses, touch LCD screen system is applicable to the configuration carried out in advance of being at ordinary times.
Fig. 4 be the display decibel that provides of the utility model preferred embodiment from tuning square dance playing device from tuning process flow diagram.As shown in Figure 4, when this device works, according to the decibel value that decibel instrument gathers, calculate the average decibel value in 5 seconds, when result of calculation is prescribed a time limit higher than on the decibel range arranged, then CPU turns down broadcast sound volume, and when result of calculation is prescribed a time limit lower than the lower of the decibel range arranged, CPU improves broadcast sound volume.So, both can accomplish to avoid different volume of music fluctuated, and need manual volume of not stopping to adjust, also volume can have been controlled in specified scope not disturb others.
Fig. 5 be the display decibel that provides of the utility model preferred embodiment from tuning square dance playing device two kinds of regulative mode operational flowcharts.As shown in Figure 5, the square dance playing device regulative mode that the utility model preferred embodiment provides is a kind of is by the push-botton operation on device, and another kind is operated by touching liquid-crystal display screen.Wherein, when evening dance on square light bad time, use push-botton operation more simple and convenient.In this, if desired make device have more operating function, can install according to the expanded function of touch LCD screen and built-in SD storage card.
In sum, the display decibel provided by the utility model preferred embodiment from tuning square dance playing device, be provided with the volume situation that decibel instrument detects surrounding environment, and by CPU audio amplifier played sound and control, to reach the effect of volume controlling audio amplifier, thus avoid volume too sound disturb residents.Meanwhile, the different buttons comprised in action button unit also make operation more convenient, avoid light bad time the single display screen playing device inconvenience that brings.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to embodiment illustrated herein, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
