Description
Technical field
The utility model belongs to electronic metronome, especially a kind of microcomputerized control metronome that has scrambler.
Background technology
Metronome is that the music-lover carries out the main rhythm marking tools in the music training, and traditional metronome mostly is physical construction, its structure more complicated, and volume is big, function singleness.Along with the progress of science and technology, advanced electronic technology has substituted original technology, and the electronic metronome that utilizes electronic technology to design has substituted mechanical metronome more and more.Existing computer control metronome is made up of singlechip controller, display, key input unit, voice IC and power amplifier output unit usually.Yet people feel in actual use, though existing electronic structure metronome has strong functions more than traditional physical construction metronome, promote the setting speed value up and down because traditional mechanical metronome is a scale, upwards or down promote the setting that scale can be finished speed.And existing electronic metronome is the setting of finishing speed by key input unit, changing to 180 such as velocity amplitude from 80 will be by speed added value 100 times, or the speed of always pinning increases key, observation display changes to 180 by 80 and just can realize, the speed of electronic metronome is regulated accomplish convenient, fast, be the problem that manufacturer transforms existing electronic metronome always.
Summary of the invention
The purpose of this utility model is the deficiency that exists at existing electronic metronome, a kind of microcomputerized control metronome that has scrambler is provided, it has avoided existing electronic metronome to adopt the loaded down with trivial details of button input setting speed, adopts scrambler can finish the setting of metronome velocity amplitude quickly and easily.
The microcomputerized control metronome that has scrambler that the utility model proposes, comprise single-chip microcomputer, the display that is connected with the single-chip microcomputer respective terminal, key input unit and voice IC, the digital volume switch of voice IC output terminal and power amplifier output unit, and casing, it is characterized in that: be provided with a scrambler, the output A of scrambler, the B end passes through R1 respectively, R2 is connected to power Vcc, the output A of scrambler, the B end is connected to two input ends of single-chip microcomputer, its A of rotary encoder or B hold output pulse signal forward or backwards, and single-chip microcomputer is finished the setting of corresponding speed value according to described pulse signal.
Originally the microcomputerized control metronome technical conceive novelty that has scrambler, reasonable in design, simple, the easy to operate advantage of the multi-functional and mechanical metronome of the sub-metronome of current collection is.It is provided with scrambler, and rotary encoder has avoided existing electronic metronome to adopt the loaded down with trivial details of button input setting speed by Single Chip Microcomputer (SCM) program setting speed value, can finish the setting of metronome velocity amplitude quickly and easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a schematic diagram of the present utility model;
Embodiment
As shown in Figure 1, 2, originally have the microcomputerized control metronome of scrambler, comprise single-chip microcomputer, display, key input unit, voice IC, digital volume switch, power amplifier output unit, scrambler and casing.Casing 1 is provided with display 2, key-press input unit 3, loudspeaker generation hole 4 and scrambler knob 5.Circuit parts such as its single-chip microcomputer, display, sound circuit and scrambler all are located on the interior circuit board of casing.
Fig. 2 as seen, and is the same with traditional product, and its display, key input unit, voice IC and digital volume switch are connected with the single-chip microcomputer respective terminal respectively, and voice IC output terminal is received the power amplifier output unit by digital volume switch.The utility model has increased a scrambler, and output A, the B end of scrambler is connected to power Vcc by R1, R2 respectively, and output A, the B end of scrambler is connected to two input ends of single-chip microcomputer, the C end ground connection of scrambler.Its A of rotary encoder or B end output forward or backwards just or the reverse impulse signal, single-chip microcomputer is finished the setting of corresponding speed value according to described pulse signal, the setting speed value exports display unit to and shows.
Described scrambler is made up of two switches, an end ground connection of its two switches.See that from the outside scrambler has A, B, three terminals of C, C holds ground connection, and the A end is the direct impulse output terminal, and the B end is the reverse impulse output terminal, and A, B end is connected to power Vcc by R1, R2 respectively during use.
Its speed setting principle is: scrambler is provided with switchgear, and in the process of rotary encoder, through this switchgear, switch motion, a scrambler wherein pin has pulse to produce, and single-chip microcomputer counts this pulse, and velocity amplitude increases.This scrambler of backward rotation, another switchgear of scrambler have pulse to produce equally, and single-chip microcomputer counts this pulse, and velocity amplitude reduces.Because of scrambler can evenly produce several as above-mentioned pulse in 360 degree scopes, single-chip microcomputer can calculate the time interval that 2 pulses count equally, and when rotation was very fast, the time interval that counts was short, and velocity amplitude is geometric series to be increased or reduce.When rotating slowly, the time interval that counts is long, and velocity amplitude increases or reduce also slow, makes velocity amplitude set only need rotate and just can finish.
The utility model course of work is as follows: the order of single-chip microcomputer accept key input block, after finishing the corresponding speed value and set according to the pulse signal of scrambler, the control sound circuit signal of sounding is selected volume by digital volume switch, sends into the power amplifier output unit then.
