This piano also includes：Controller.

Controller is made up of YF015 chip and ISD1820 chip two chips.

The PC0-PC3 pin of YF015 chip is connected with PA0-PA3, PB0-PB3 pin the sound being output as without tone respectively Electric capacity button is used to connect as switch between sound, and two pins.Not same tone will be exported when pressing different electric capacity button Sound.

ISD1820 chip is connected to three electric capacity buttons, a microphone and two loudspeaker, and three electric capacity buttons are respectively Start recording, single pass is play and electronic broadcasting.Loudspeaker are placed in base bilateral wall and give symmetrical, are divided into left and right acoustic channels.

Further, switch adopts electric capacity button, gives user and preferably experiences.

Further, described loudspeaker lay with base side wall on, symmetrically put.

Further, described microphone is placed on the center of top cover.

Further, its control chip is YF015 chip and ISD1820 chip.

As can be seen from the above technical solutions, this utility model embodiment has advantages below：

One kind small-sized touch pianotron that this utility model provides, this qin has recording broadcast using ISD1820 chip Function, also can send the sound of not same tone using YF015 chip, and use electric capacity button touch, eliminate biography The mechanical key of system, gives user and preferably experiences.Ben Qin does not need to adopt Single-chip Controlling, and circuit is simple, low cost.And This qin is light, is suitable to child and carries, plays with.Child can be excited well to learn the interest of piano, applied range, energy is very well Ground lifting Consumer's Experience, is the bigger practical value of social creativity.

Specific embodiment

This utility model provides a kind of multifunctional portable and touches upright piano, and can open record by touching electric capacity button Sound, the function such as broadcast, thus this piano has function many, highly reliable, entertaining and other effects.

In order that those skilled in the art more fully understand this utility model scheme, 1 to accompanying drawing 5 is simultaneously below in conjunction with the accompanying drawings In conjunction with specific embodiment, the utility model is described in further detail.

A kind of Multifunctional touching upright piano below this utility model being provided illustrates, the piano in this utility model Embodiment specifically includes：

In figure：1st, top cover；2nd, base；3rd, electric capacity button；4th, microphone；5th, power module 6, ISD1820 chip；7、YF015 Chip

In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and tool Body embodiment is described in further detail to this utility model, it should be noted that in the case of not conflicting, the application's Feature in embodiment and embodiment can be mutually combined.

As shown in figure 1, small-sized touch pianotron, including top cover 1 and base 2, wherein top cover includes electric capacity button 3 He Microphone 4, base includes the loudspeaker 8 of side wall and the power module 5 of bottom, ISD1820 chip 6, YF015 chip 7.Touching top cover Electric capacity button, will closure connect YF015 chip two pins, output signal sends sound from loudspeaker 8.In the same manner, touch The electric capacity button of top cover, it will promote recording or the broadcast of ISD1820 chip.
