Projection device for generating simulation piano and work method of projection device

Abstract

The invention provides a projection device for generating a simulation piano and a work method of the projection device. The projection device for generating the simulation piano comprises a projection module for carrying out projection to generate a piano keyboard image, tracking contact position between a user and the piano keyboard image and enabling the contact position to be generated into data information; an information processing module connected with the projection module and used for carrying out processing on the data information to generate audio data, wherein the audio data is used for driving an audio device to product sound; and an audio signal transmitter connected with the information processing module and used for transmitting the audio data. The projection device for generating the simulation piano is small in occupation space and low in cost; effect and form of the generated simulation piano are much closer to those of a real piano; and the device brings more fun to the users.

Description

technical field [0001] The invention relates to the field of projection, in particular to a projection device for generating simulated pianos and a working method of the projection device. Background technique [0002] Nowadays, the popularity of pianos is not high, and families with pianos only account for a small part of the social group. One is that pianos are expensive, and the other is that pianos are relatively large and take up a lot of space. In today’s mobile phone software, Although the existing piano application can simulate the keys and sounds of the piano, it is limited due to the size of the mobile phone screen. The piano application cannot allow users to enjoy the beauty of the piano as if they were on the scene, which prevents some music lovers from being themselves. favorite music. For example, please refer to figure 1 , is a piano application in the prior art. Due to the limitation of the mobile phone screen, there are only 6 white keys and 4 black keys i...

[0002] Nowadays, the popularity of pianos is not high, and families with pianos only account for a small part of the social group. One is that pianos are expensive, and the other is that pianos are relatively large and take up a lot of space. In today’s mobile phone software, Although the existing piano application can simulate the keys and sounds of the piano, it is limited due to the size of the mobile phone screen. The piano application cannot allow users to enjoy the beauty of the piano as if they were on the scene, which prevents some music lovers from being themselves. favorite music

For example, please refer to figure 1 , is a piano application in the prior art. Due to the limitation of the mobile phone screen, there are only 6 white keys and 4 black keys in the piano application, while a general physical piano has 88 keys. The keys in the piano application The number of keys is far from the number of keys of a physical piano, which means that the piano application cannot provide users with a realistic piano playing experience, nor can it provide all the tones of the piano, so the performance effect will certainly not be comparable to that of a physical piano
