Description
Technical field
It the utility model is related to speaker digital display circuit, more particularly to a kind of speaker digital indicator.
Background technology
At present, the loudspeaker working status in existing Horn loudspeaker box does not have numerical monitor, and what is occurred when speaker works is short
Situations such as road, open circuit, wiping circle, peak value, peak valley, can not be very clear, and when more speakers are spoken together, human ear is difficult which is differentiated
Which loudspeaker of a speaker there is a problem, very inconvenient maintenance.Therefore, visual discrimination just seems particularly significant.Therefore research and development one
Kind speaker digital indicator, becomes those skilled in the art's urgent problem to be solved.
Utility model content
The utility model is to solve above-mentioned deficiency, there is provided a kind of speaker digital indicator, for speaker inside trumpet
The numerical monitor of working status.
The above-mentioned purpose of the utility model is realized by following technical solution：A kind of speaker digital indicator, it is special
Sign is：Including loudspeaker group, the loudspeaker string formation joins the resistance for being less than 0.1 ohm, described one numeral of resistor in parallel
Voltmeter, the output terminal of a digital voltmeter regulated power supply in parallel, while a battery in parallel or super capacitor, regulated power supply
Input terminal it is in parallel with loudspeaker group；One manual or electricity is set on the parallel circuit of the battery or super capacitor and digital voltmeter
Control switch.
The loudspeaker string formation joins a frequency divider.
The loudspeaker group includes several loudspeaker in series or in parallel with each other.
A kind of design method of the speaker digital indicator of the utility model：
The design of Part I：One small resistor of string on the binding post of every loudspeaker, generally at 0.1 ohm once, is surveyed
Measure its voltage.Resistance selection is generally in the noninductive resistance of loudspeaker impedances 1% or so.After resistance determines, what is considered is electric current,
Loudspeaker maximum bear electric current 200% be exactly resistance allow maximum current.Digital voltmeter is terminated in resistance two, uses voltmeter
Numeral reflects the current intelligence of speaker.Above-mentioned is the Part I of the instrument；
The design of Part II：Digital voltmeter needs a metastable power supply power supply, therefore designs a voltage stabilizing electricity
Source；
The design of Part III：When loudspeaker Power operation is when compared with low state, regulated power supply cannot work on.At this moment
Require the 3rd power supply power supply.3rd Power Management Design is one piece of fixed battery；
The design of Part IV：It will go wrong when fixed battery does not have electricity；At this moment just one power supply of needs is
It charges, this power supply and regulated power supply are all to obtain source from loudspeaker operating power, can be fixed electricity under working status
Charge in pond；The power supply merges into a single whole with regulated power supply.
The digital voltmeter of the utility model forms digital electronic ammeter together with resistance.
The utility model compared with prior art the advantages of be：The speaker digital indicator of the utility model can make speaker loudspeaker
Short circuit, open circuit, wipe circle, wave crest, trough, input to speaker power situation etc. it is all very clear.When more speakers together
When speaking, it is inconsistent with other loudspeaker numerals intuitively to tell the display numeral of which speaker, judges to be likely to occur and asks
Topic, easy to repair, maintenance.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
The utility model is described in further detail with reference to embodiment.
As shown in Figure 1, a kind of speaker digital indicator, including loudspeaker group 1, the loudspeaker group 1, which is connected one, is less than 0.1 Europe
The resistance 2 of nurse, a digital voltmeter 3 in parallel on the resistance 2, the output of the regulated power supply 4 in parallel of digital voltmeter 3
End, while a battery in parallel or super capacitor 5, the input terminal of regulated power supply 4 are in parallel with loudspeaker group 1；The battery or super electricity
Hold 5 with setting a manual or electric-controlled switch 6 on the parallel circuit of digital voltmeter 3.
One frequency divider 7 of the series connection of loudspeaker group 1.
The loudspeaker group 1 includes several loudspeaker in series or in parallel with each other.
A kind of design method of the speaker digital indicator of the utility model：
The design of Part I：One small resistor of string on the binding post of every loudspeaker, generally at 0.1 ohm once, is surveyed
Measure its voltage.Resistance selection is generally in the noninductive resistance of loudspeaker impedances 1% or so.After resistance determines, what is considered is electric current,
Loudspeaker maximum bear electric current 200% be exactly resistance allow maximum current.Digital voltmeter is terminated in resistance two, uses voltmeter
Numeral reflects the current intelligence of speaker.Above-mentioned is the Part I of the instrument；
The design of Part II：Digital voltmeter needs a metastable power supply power supply, therefore designs a voltage stabilizing electricity
Source；
The design of Part III：When loudspeaker Power operation is when compared with low state, regulated power supply cannot work on.At this moment
Require the 3rd power supply power supply.3rd Power Management Design is one piece of fixed battery；
The design of Part IV：It will go wrong when fixed battery does not have electricity；At this moment just one power supply of needs is
It charges, this power supply and regulated power supply are all to obtain source from loudspeaker operating power, can be fixed electricity under working status
Charge in pond；The power supply merges into a single whole with regulated power supply.
The digital voltmeter of the utility model forms digital electronic ammeter together with resistance.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
