Description
Technical field
The utility model is related to a kind of physics teaching demonstrating instrument device, especially a kind of sound three elements demonstrator.
Background technology
Sound related content is the content run at first of junior middle school student's learning physicses, in the relevant knowledge system of sound
In, the three elements of sound are the emphasis of study, but not only price is high because of old-fashioned oscillography instrument, and are difficult to accomplish same
Shi Rangquan classes of student can see the image on oscillography instrument, therefore teacher is rarely employed oscillography instrument to be imparted knowledge to students, and makes
Teacher it is all more abstract when saying sound-content, it is difficult to student show sound three elements for sound specific influence,
Therefore student is difficult the understanding for producing image to these contents, causes understanding to be got up relatively difficult.At present also can not be in class
One's parents carry out on-the-spot demonstration using multimedia and are available for full class classmate while watching the experiment of phenomenon.
The content of the invention
For above-mentioned problem, the purpose of this utility model is to provide a kind of sound three elements demonstrator, the demonstration
The multimedia large-size screen monitors that instrument small volume, the waveform for being easy to carry and can producing sound are equipped with by now basic each classroom
Curtain is shown, it is adaptable to classroom instruction or activity to popularize scientific knowledge, is easy to full class student and all spectators to watch simultaneously, improves teaching effect
Really.
The technical solution of the utility model is to provide a kind of sound three elements demonstrator, wherein：The demonstrator includes phase
The microphone that connects, main frame, USB data line, and supporting software；The main frame includes input interface, circuit module, output
Interface, shell, the pin of the input interface and output interface are connected with circuit module, the input interface and output interface
Expose shell in interface one end；The microphone connects input interface, and USB data line is connected with circuit module and enters data into meter
Calculation machine, software installation receives the signal from USB data line in computer；The circuit module includes the sound being connected with each other
Signal acquisition and amplification module, AD conversion module, logic module, MCU control module, power supply and USB output modules, voice signal
Collection with amplification module collected sound signal, by AD conversion module, logic module, MCU control module processing after through power supply and
USB output modules are transferred to computer, pass through software display waveform.
The beneficial effects of the utility model are：
(1) the utility model directly can gather various voice signals by microphone, be shown with image, numerical value two ways
Input the three elements of sound：Tone (i.e. frequency), loudness (i.e. amplitude) and tone color.
(2) the utility model can by collection in worksite to sound be shown in real time by computer on projection screen for complete
Class student or theater watch simultaneously.
(3) software of the present utility model can intercept certain flashy static waveform at any time and carry out static observations and research.
