Abstract
The invention discloses a virtual piano which comprises a plurality of groups of keys. The virtual piano is characterized in that a pressure sensor is arranged below each key, and is connected with a single-chip microcomputer module, wherein a sound production equipment module is connected to the single-chip microcomputer module; when the virtual piano works, pressure sensor modules 3 of each group correspond to the eight sounds Do, re, mi, fa, so, la, ci and do. When the keys are played, the pressure sensor modules transmit signals to the single-chip microcomputer module after detecting percussion force, and the single-chip microcomputer module controls the sound production equipment module to produce corresponding sounds when receiving the signals from the pressure sensor modules, and stops working when pressure is eliminated.
Description
Technical field
The present invention relates to a kind of piano, particularly a kind of virtual piano.
Background technology
Current piano is complicated and expensive, so devise a kind of virtual piano.
Summary of the invention
Object of the present invention is exactly to solve the problem mentioned in above-mentioned background technology, provides a kind of virtual piano.
The technical solution used in the present invention is: a kind of virtual piano, comprise some groups of keys, it is characterized in that: under each key, lay a pressure transducer, each pressure transducer is connected with an one-chip computer module, described one-chip computer module connects an audible device module, often organizes pressure sensor module 3 corresponding Do, re, mi, fa, so, la, ci, do8 sound during work.When playing key, sensor assembly sends signal to described one-chip computer module after hitting power being detected, described one-chip computer module receives signal that described pressure sensor module sends and just controls audible device module and send corresponding sound, when pressure is eliminated, one-chip computer module just quits work.
Preferably, described key can be 4 groups and arrange from the top down, also can from left to right arrange.
Preferably, described key can be wooden also can be transparent membrane.
Embodiment
A kind of virtual piano, comprise some groups of keys, it is characterized in that: under each key, lay a pressure transducer, each pressure transducer is connected with an one-chip computer module, described one-chip computer module connects an audible device module, often organizes pressure sensor module 3 corresponding Do, re, mi, fa, so, la, ci, do8 sound during work.When playing key, sensor assembly sends signal to described one-chip computer module after hitting power being detected, described one-chip computer module receives signal that described pressure sensor module sends and just controls audible device module and send corresponding sound, when pressure is eliminated, one-chip computer module just quits work.Described key can be 4 groups and arrange from the top down, also can from left to right arrange.Described key can be wooden also can be transparent membrane.
