Description
Technical field
The utility model relates to toy technique field, specifically a kind of combinable decibel instrument.
Background technology
Decibel instrument is the most basic noise-measuring instrument, is again sound meter or noisemeter.The principle of work of decibel instrument is: convert tones into electric signal by microphone, then by prime amplifier transforming impedance, microphone is mated with attenuator.Output signal is added to weighting network by amplifier, spectrum overlapping (or external filters) is carried out to signal, and then through attenuator and amplifier, signal is amplified to certain amplitude, deliver to rms detector (or outward by level recorder), provide the numerical value of noise level over the display.
The decibel instrument sold in the market is all fixing, complete shaping, user can direct control for detecting noise, but these decibel of instrument interest is low, is unfavorable for that children for learning understands the principle of work of decibel instrument, and improves children's manipulative ability.Therefore, need a kind of combinable decibel instrument of exploitation badly, decibel instrument is changed into modules, is connected by wire, allow children in the circuit theory of the process learning decibel instrument played.
Utility model content
The utility model for above-mentioned Problems existing, provide a kind of interest strong, teach through lively activities can assembled decibel instrument.
The utility model for achieving the above object, takes following technical scheme to be achieved:
A kind of combinable decibel instrument, comprises power module, switch module, micro treatment module, sound source receiver module, horn module and wire transmitting module; Described power module, switch module and micro treatment module are connected to form loop by wire transmitting module; Described micro treatment module connects sound source receiver module and horn module respectively, and the other end of described sound source receiver module connects the negative pole of power module, and the other end of described horn module connects the positive pole of power module.
More directly perceived and possess interest in order to make decibel instrument detect noise intensity, preferably, also comprise and extremely run lamp module, the both positive and negative polarity of described cruel race lamp module connects the both positive and negative polarity of power module respectively, and described micro treatment module runs lamp module be connected with cruel.
Preferably, described sound source receiver module is microphone.Microphone can be crystal formula, electret-type, moving-coil type or condenser type.
Preferably, described micro treatment module surface is provided with the display screen of display noise level numerical value.
Preferably, the link of described each module is equipped with the metal primary and secondary hasp of circuit connection, and described metal primary and secondary hasp comprises metal sub-buckle and metal box.

Compared with prior art, the beneficial effects of the utility model are as follows: the utility model forms a combinable decibel instrument by power module, switch module, micro treatment module, sound source receiver module, horn module and wire transmitting module, in addition, in order to make decibel instrument detection noise intensity more directly perceived and possess interest, set up and extremely run lamp module, the size of noise volume is represented intuitively by the number that lamp is bright, be conducive to improving children's interest, allow children in the circuit theory of the process learning decibel instrument played, improve manipulative ability, reach the object of teaching through lively activities.
Accompanying drawing explanation
Fig. 1 is the structural representation of the combinable decibel instrument of the utility model;
Fig. 2 is another structural representation of the combinable decibel instrument of the utility model;
Fig. 3 is wire transmitting module structural blast figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
See Fig. 1 ~ 3, a kind of combinable decibel instrument, comprises power module 1, switch module 2, micro treatment module 3, sound source receiver module 4, horn module 5 and wire transmitting module 6; Power module 1, switch module 2 and micro treatment module 3 are connected to form loop by wire transmitting module 6; Micro treatment module 3 connects sound source receiver module 4 and horn module 5 respectively, and the other end of sound source receiver module 4 connects the negative pole of power module 1, and the other end of horn module 5 connects the positive pole of power module 1.
Sound source receiver module 4 is preferably microphone.Microphone can be crystal formula, electret-type, moving-coil type or condenser type.
Micro treatment module 3 surface is provided with the display screen 8 of display noise level numerical value.
See Fig. 2, more directly perceived and possess interest in order to make decibel instrument detect noise intensity, preferably, also comprise and extremely run lamp module 7, the cruel both positive and negative polarity running lamp module 7 connects the both positive and negative polarity of power module 1 respectively, and micro treatment module 3 runs lamp module 7 be connected with cruel.Cruel race lamp module 7 is equivalent to a noise volume intensity indicator, when ambient sound changes, not only display screen 8 can show decibel value, cruel race lamp module 7 can also show current volume simultaneously, sound is larger, and cruel LED of running on lamp module is bright must be more, and sound is less, LED on cruel race lamp module is bright must be fewer, and this display is a kind of directly perceived, general instruction.And display screen 8 display is detailed, concrete noise level numerical value.
See Fig. 3, conveniently operate, the link of each module is equipped with the metal primary and secondary hasp of circuit connection, and metal primary and secondary hasp comprises metal sub-buckle 9 and metal box 10.Decibel instrument is provided with insulating base 11 supporting with it, insulating base 11 is equidistantly provided with some protruding 12, and metal box 10 fastens 12 with protruding.
Principle of work of the present utility model is as follows: microphone converts tones into electric signal, and the prime amplifier being input to micro treatment module after sampling by certain sampling rate amplifies.Output signal is delivered to the analog-to-digital conversion circuit of micro treatment module by amplifier, simulating signal is converted to digital signal, digital signal is delivered on display screen 8 and is shown decibel value after computing and process, simultaneously, again digital signal is converted into the cruel intensity of sound digital signal of running lamp and can identify, outputted to by connection wire and extremely run lamp module, cruel race lamp module simultaneous display volume.
Compared with prior art, the beneficial effects of the utility model are as follows: the utility model forms a combinable decibel instrument by power module, switch module, micro treatment module, sound source receiver module, horn module and wire transmitting module, in addition, in order to make decibel instrument detection noise intensity more directly perceived and possess interest, set up and extremely run lamp module, the size of noise volume is represented intuitively by the number that lamp is bright, be conducive to improving children's interest, allow children in the circuit theory of the process learning decibel instrument played, improve manipulative ability, reach the object of teaching through lively activities.
Only as described above, be only the preferred embodiment of the utility model, when can not limit the scope of the utility model enforcement with this, namely generally according to equivalence change simple done by the content described in the utility model claim and utility model instructions and modification, all still belong within the utility model claim scope.In addition, summary part and title are only used to the use of auxiliary patent document search, are not used for the interest field of restriction the utility model.
