Abstract
The utility model discloses a kind of small mouse shape sounding musical instrument based on SCM program, it is made up of mouse-like shell, single-chip microcomputer, battery, socket, note button and pitch button, sounding carrier is designed to mouse-like, as mouse-like shell, its indoor design has neck to fix the position of single-chip microcomputer, and equipped with battery, it can be charged by outside socket.It is in double note button that seven are designed with above mouse-like shell, and this seven buttons correspond to the pronunciation of 1,2,3,4,5,6,7 seven notes of music respectively；There are three pitch buttons the side of mouse-like shell to control pronunciation high, normal, basic.When note button and pitch button are pressed, input port is pulled low, and single-chip microcomputer produces the square wave of respective frequencies using internal clocking, and the sound of respective frequencies is sent by external circuit drive the speaker.The utility model breaches the characteristics of traditional instrument volume is big expensive, realizes the purpose played on small container, and significantly reduce cost.
Description
Technical field
The present invention relates to a kind of sounding musical instrument, especially a kind of small container sounding musical instrument based on SCM program.
Background technology
Musical instrument is greatly enriched the free life of the mankind, but musical instrument prevailing price in the market is costly,
Part musical instrument volume ratio is huger, and its not easy to operate, therefore really popularization is relatively limited.In order to overcome disadvantage mentioned above, if
Counted it is this sounding can be realized on small mouse shape carrier based on singlechip technology, realizing cost greatly reduces,
Mouse-like carrier, makes its extremely simple of operating；It is programmed additionally by single-chip microcomputer, it is possible to achieve different tone colors
So as to form different sounding musical instruments, have broad application prospects.
Chinese patent discloses a kind of " music box " design based on AT89S52 single-chip microcomputers, and system is realized using Independent keys
All kinds of controls conversion of system.But this kind of invention is only applicable to the switching between existed system, and subjective initiative is removed without people
Operate to realize sounding that oneself is desired.
Therefore the mouse-like musical instrument this simple to operation and low cost based on single chip application is required, and is
It is not reached so far.
The content of the invention
The invention aims to overcome the shortcoming of the above, have devised one kind based on SCM program to be played
The small mouse shape musical instrument of function, the invention provides a kind of simplicity is portable, cost is relatively low, a kind of feature-rich musical instrument.
Realize that above-mentioned purpose can be achieved through the following technical solutions：
A kind of small mouse shape sounding musical instrument based on SCM program, by mouse-like shell, single-chip microcomputer, battery, socket,
Note button and pitch button composition, sounding carrier are designed to mouse-like, as mouse-like shell, and its indoor design has neck
The position of fixed single-chip microcomputer, and equipped with battery, it can be charged by outside socket.It is designed with above mouse-like shell
Seven are in double note button, and a row has three note buttons, and another row has four note buttons, hand-held mouse shape shell
When, three note buttons of forefinger, middle finger and nameless three note buttons being responsible for by first row or second row, little finger is only
It is responsible for the 4th note button by another row；This seven buttons correspond to 1,2,3,4,5,6,7 seven sounds of music respectively
The pronunciation of symbol；There are three pitch buttons the side of mouse-like shell to control pronunciation high, normal, basic, and pitch button can be by thumb control
System.
A kind of small mouse shape sounding musical instrument based on SCM program of the present invention, described mouse-like shell is by polymerizeing
Thing material is made.
In a kind of small mouse shape sounding musical instrument based on SCM program of the present invention, the shell of described mouse-like shell
Shape is designed as being adapted to the mouse-shaped of palm held.
In a kind of small mouse shape sounding musical instrument based on SCM program of the present invention, described outlet can be used
USB interface, charges to internal cell.
In a kind of small mouse shape sounding musical instrument based on SCM program of the present invention, described sounding carrier inside neck
Structure can fix the position of single-chip microcomputer.
In a kind of small mouse shape sounding musical instrument based on SCM program of the present invention, the internal processes of described single-chip microcomputer
It is the input port connection microswitch of single-chip microcomputer, and sets input port to be inputted for pull-up, whether inquiry is low per 20ms
Level.When microswitch is pressed, input port is pulled low, and single-chip microcomputer produces the square wave of respective frequencies using internal clocking, is led to
Cross the sound that external circuit drive the speaker sends respective frequencies.
In a kind of small mouse shape sounding musical instrument based on SCM program of the present invention, described single-chip microcomputer and loudspeaker it
Between be that the port of single-chip microcomputer is connected and current-limiting resistance and then connects loudspeaker, the other end of loudspeaker is connected to VCC (power supply electricity
Pressure).
The present invention effect be：The characteristics of traditional instrument volume is big expensive is breached, realizes and is played on small container
Purpose, and significantly reduce cost.
