Abstract

The invention relates to a portable piezo-ceramic instrument tone recognition system and solves the problem that the existing equipment is inconvenient to carry. The portable piezo-ceramic instrument tone recognition system comprises a piezo-ceramic tone recognizer and a smart phone with installed tone recognition software. The output end of the piezo-ceramic tone recognizer is connected with the smart phone through a wire or in a wireless transmission manner. The tone recognition software mainly comprises a communication module, a fast Fourier transform module, a tone recognition module, a common instrumental tone standard frequency library, a tone evaluation module and a user interface. Built-in instrumental tones are stored in the common instrumental tone standard frequency library in the smart phone. The tone recognition software is used for analyzing electrical signals collected by the piezo-ceramic tone recognizer, matching the electrical signals with the built-in instrumental tones, and evaluating precision of the instrumental tones. The piezo-ceramic tone recognizer comprises piezo-ceramic, a trigger circuit, a power amplifier module, a noise elimination module, an analog-to-digital conversion module, a data transmission module and a power module. The portable piezo-ceramic instrument tone recognition system has the advantages of convenience of carrying and capability of auto-judging musical tones of common instruments. With the system, people can precisely, conveniently and quickly adjust basic tones of instruments before a performance.

Description

technical field [0001] The invention relates to a sound recognition device, in particular to a portable piezoelectric ceramic musical instrument sound recognition system. Background technique [0002] In today's human life, the popularity of musical instruments is getting wider and wider, people's demand for musical instruments is getting higher and higher, and there are more and more new occupations and science and technology derived from it. In order to meet people's needs for identifying the pitch and timbre of musical instruments, tuning fork tools have appeared in history. With the improvement of the level of science and technology, various electronic tone discrimination technologies are also developing day by day. For example, the guitar pickups and record players sold on the market use electromagnetic technology to distinguish the tone, timbre, etc. of the tone. express accurately. But, the ubiquitous problem of inconvenient portable of existing sound recognition eq...
