The sound adjusted, gives user and preferably experiences.
For achieving the above object, this utility model be employed technical scheme comprise that:
One kind small-sized touch pianotron that this utility model provides, including body, this body has top cover and base, top
Lid can be divided into eight parts, center circle and surrounding remainder to be divided into 7 parts, and around 7 parts are embedded with an electric capacity respectively
Button with the YF015 chip of connect base, central circular portion be embedded with three electric capacity buttons with and a microphone with connect base
ISD1820 chip.
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.
