Description
Technical field
The present invention relates to a kind of circuit, specifically a kind of music integrated circuit, belongs to music integrated circuit technical field.
Background technology
Along with the development of modern science and technology technology, the requirement of the quality of people to life is also more and more, how can live more comfortable be the common topic of current mankind society, just imagine, having lunch, whether very comfortable listen the life of music, the electronic product of playing at present music has a lot, for example MP3, mobile phone, sound equipment, computer etc., these electronic products have individual common ground, its inner too complexity of circuit design of playing music, and price is high, be unfavorable for generally applying.Some circuit has the control such as single-chip microcomputer or PLC to realize, and these circuit theory complexity are difficult to design, therefore extremely urgent to the design of simple broadcasting music circuit.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of music integrated circuit, and design principle is simple, and cost is low, easily realizes, and is conducive to generally apply.
To achieve these goals, the technical solution used in the present invention is: a kind of music integrated circuit, comprise integrated chip HY-100, switch S, light-emitting diode VD, transistor VT, 3V power supply and loud speaker B, the pin one of integrated chip HY-100 is in one end of switch S, the positive pole of light-emitting diode VD, one end of loud speaker B, the positive pole of 3V power supply connects, the pin two of integrated chip HY-100 is connected with the other end of switch S, the pin 3 of integrated chip HY-100 is connected with the base stage of transistor VT, the collector electrode of transistor VT is connected with the negative pole of light-emitting diode VD, the pin 5 of integrated chip HY-100 is connected with the other end of loud speaker B, the pin 6 of integrated chip HY-100 and the emitter of transistor VT, the negative pole of 3V power supply connects.
Further, described loud speaker B is crystal formula loud speaker.
Further, described switch S is double control switch.
The invention has the beneficial effects as follows: adopt integrated chip HY-100, switch S, light-emitting diode VD, transistor VT, 3V power supply and loud speaker B to form a simple music playing circuit, design principle is simple, cost is low, easily realizes, and is conducive to generally apply.
Brief description of the drawings
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of music integrated circuit, comprise integrated chip HY-100, switch S, light-emitting diode VD, transistor VT, 3V power supply and loud speaker B, the pin one of integrated chip HY-100 is in one end of switch S, the positive pole of light-emitting diode VD, one end of loud speaker B, the positive pole of 3V power supply connects, the pin two of integrated chip HY-100 is connected with the other end of switch S, the pin 3 of integrated chip HY-100 is connected with the base stage of transistor VT, the collector electrode of transistor VT is connected with the negative pole of light-emitting diode VD, the pin 5 of integrated chip HY-100 is connected with the other end of loud speaker B, the pin 6 of integrated chip HY-100 and the emitter of transistor VT, the negative pole of 3V power supply connects.
Described loud speaker B is crystal formula loud speaker.
Described switch S is double control switch.
The course of work: the circuit being made up of integrated chip HY-1OO is a kind of extensive CMOS integrated circuit.This circuit is integrated in all circuit including preamplifier and power amplifier on the printed circuit board of a 25mm * 15mm by CMOS technology, on chip, be welded with the resistance of a 68k, the music integrated circuit being made up of integrated chip HY-100 has driving force greatly and output uses feature flexibly, wherein the pin 5 of integrated chip HY-100 is power take-off, can directly drive loud speaker.The pin 3 of integrated chip HY-100 is preamplifier outputs, can be used for promoting piezoelectric buzzer work or promotes transistor VT.HY-100 series music integrated circuit is one can be used as the circuit of playing music, and when trigger the trigger end of pin two pin of integrated chip HY-100 by positive pulse, it just can be about melody by automatic Playing.The S that closes a switch can drive the music playing circuit of loud speaker B and light-emitting diode VD simultaneously, and light-emitting diode VD can be luminous with melody.
