Technical field
The present invention relates to a kind of pinned LED of integrated music encapsulation.
Background technology
LED has the advantages such as luminous efficiency is high, long service life, good stability, is widely used in lighting field.In traditional concept, LED only has illumination functions, and loudspeaker only have the function of sounding.If need to carry out acousto-optic instruction in system simultaneously, can only adopt discrete device to carry out acousto-optic operation, in the luminous and sounding type system that existing discrete device forms, exist number of devices many, the problem such as volume is large, need to control respectively, has limited the application of acousto-optical device in the harsher system of volume ratio.For example, Chinese patent CN302613991 is a kind of music LED mini light night, the structural design that its design focal point is product, and wherein emitting led, microphone device still adopts conventional discrete device.Chinese patent CN202470005 is a kind of music Lamp cup, comprises LED, control chip, power supply and loudspeaker on Lamp cup, still adopts discrete device, and whole system volume ratio is larger.
Summary of the invention
Inconvenience while use for existing acoustic luminous device is discrete, the pinned LED that the object of the present invention is to provide a kind of integrated music to encapsulate, has reduced circuit element quantity, improves element integrated level and reliability.
To achieve the above object, design of the present invention is:
That the present invention realizes is emitting led, music integrated circuit, piezoelectric ceramic piece integration packaging together, only have two pins, directly luminous and send curing musical sound after energising.
According to above-mentioned design, the technical solution used in the present invention is:
A kind of pinned LED of integrated music encapsulation, comprise emitting led, music integrated circuit and piezoelectric ceramic piece, described emitting led, music integrated circuit and piezoelectric ceramic piece are packaged together, described music integrated circuit is encapsulated in emitting led bottom, again piezoelectric ceramic piece is encapsulated in to the bottom of music integrated circuit, finally draw two metal pins, direct and power supply joins.
Described be emitting ledly connected with the both positive and negative polarity of metal pins respectively with the both positive and negative polarity of music integrated circuit, the positive pole of piezoelectric ceramic piece is connected to the collector electrode of the inner integrated amplification triode of music integrated circuit, and the negative pole of piezoelectric ceramic piece is connected on the negative pole of metal pins.
Described music integrated circuit is solidified with music.
Compared with prior art, the present invention has following outstanding substantive distinguishing features and significant advantage:
The present invention is made up of prior art luminous, sound-producing device discrete device LED, loudspeaker etc. adopt integrated technology, overall package together, reduce number of elements, reduce circuit volume, improve system reliability, provide a kind of simple in structure, integrated level is high, the pinned LED of the integrated music of good reliability encapsulation.Ensureing on the basis of traditional LED luminous characteristics, this system can be sent the music of various IC inside solidifications, be with a wide range of applications in fields such as signal designation, state-detection, toys, be specially adapted to components and parts overall volume to require harsher system.The wherein encapsulation diameter of system, operating voltage and whether encapsulate current-limiting resistance, can design according to actual needs.

Embodiment
Also describe by reference to the accompanying drawings system feature of the present invention in detail by specific embodiments of the invention below.
A kind of pinned LED of integrated music encapsulation, comprise emitting led 1, music integrated circuit 2 and piezoelectric ceramic piece 3, described emitting led 1, music integrated circuit 2 and piezoelectric ceramic piece 3 are packaged together, described music integrated circuit 2 is encapsulated in emitting led 1 bottom, again piezoelectric ceramic piece 3 is encapsulated in to the bottom of music integrated circuit 2, finally draw two metal pins, direct and power supply joins.
Described emitting led 1 is connected with the both positive and negative polarity of metal pins respectively with the both positive and negative polarity of music integrated circuit 2, the positive pole of piezoelectric ceramic piece 3 is connected to the collector electrode of the inner integrated amplification triode of music integrated circuit 2, and the negative pole of piezoelectric ceramic piece 3 is connected on the negative pole of metal pins.Described music integrated circuit 2 is solidified with music.
As shown in Figure 1, music integrated circuit 2 is a kind of large-scale CMOS integrated circuits, connects simple external circuit, can send the sound of simple melody, voice or various simulations.Music integrated circuit 2 mainly comprises control circuit, cycling circuit, oscillating circuit, memory, tone circuit and transistor amplifying circuit five part compositions.At the integrated transistor of music integrated circuit 2 own, drive piezoelectric ceramic piece 3, in improving voice output volume, further reduce system bulk than traditional circuit, and between the collector electrode of transistor and base stage, an integrated feedback capacity, can effectively suppress self-excitation.The signal that oscillating circuit produces is for each circuit, control circuit is read the code from memory, control metronome and the co-ordination of tone device according to code, produce corresponding music signal, then amplify rear drive piezoelectric ceramic piece through transistor and send out into euphony.The music that music integrated circuit 2 is sent is solidificated in internal storage.Concrete which kind of music signal of output is to have internal control circuit and external trigger circuit to determine.In the present invention, be divided into the happy output of single-tone and two series of the happy output of multitone, and system powers on and power-off signal is outer triggering signal.When the happy output mode of single-tone, only in internal storage, solidify the desired single song of client, after system powers on, export same a piece of music always, after power-off, music stops output.When the happy output mode of multitone, can in internal storage, solidify the desired many songs of client, circulation is broadcasted successively, replays First music after power-off.Music integrated circuit internal structure block diagram.
As shown in Figure 2, wherein the encapsulation diameter of device can encapsulate according to the actual requirements, and as emitting led 1 being ￠ 5mm, music integrated circuit 2 is ￠ 4mm, and piezoelectric ceramic piece 3 is ￠ 4mm.Emitting led 1 both positive and negative polarity is connected with external power source by two pins, and wherein long pin is anodal, and short pin is negative pole.The audio frequency output of music integrated circuit 2 is amplified through inner integrated triode, thereby drives piezoelectric ceramic piece 3, carries out music.Wherein emitting led 1 luminous brightness, the decibels that piezoelectric ceramic piece 3 is play music can be controlled by the current-limiting resistance in external power source loop, and for occupation mode is flexibly provided, the system current-limiting resistance in this example is not encapsulated in the inside of system.In order to adapt to more application scenario, operating voltage of the present invention is set to 3～6V, meets different needs.
