Description
Technical field:
The utility model relates to a kind of learning assistant instrument for stringed instrument, belongs to stringed musical instrument apparatus technical field.
Background technology:
Stringed musical instrument is an important branch in musical instrument family, and in classical music and even modern light music, nearly all lyric melody is all played by string music part.Visible, soft and graceful, interesting to listen to is the common trait of all stringed musical instruments.The tone color of stringed musical instrument is unified, has multi-level expressive force: surge impassioned during (instrumental) ensemble, during solo, tenderness is graceful and restrained; Again because of the changeable bowing of horn of plenty (quiver, broken, dial, jump, etc.) and there is agile color.
Existing stringed musical instrument is sometimes difficult to tell elastic force or the pressure while playing in the process of study, cause the string sound played out interesting to listen to not, this just needs a kind of learning assistant instrument for stringed instrument that can tell string sound, but auxiliary machine in the market does not possess this function.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of learning assistant instrument for stringed instrument.
A kind of learning assistant instrument for stringed instrument of the present utility model, it comprises base, display screen, rotating shaft, acoustic pickup, sucker, single-chip microcomputer, audio-frequency generator, LED audio frequency table driver, loudspeaker, the top of base is connected with display screen by rotating shaft, in base, be separately installed with single-chip microcomputer, audio-frequency generator, LED audio frequency table driver, loudspeaker, acoustic pickup is installed on sucker, acoustic pickup is connected with single-chip microcomputer by wire, single-chip microcomputer is connected with audio-frequency generator, audio-frequency generator respectively with LED audio frequency table driver, loudspeaker connects, LED audio frequency table driver is connected with display screen.
As preferably, the bottom of described base is bonded with skid resistant course.
As preferably, the rear portion of described base is connected with bracing frame by regulating shaft.
The beneficial effects of the utility model are: can make player find out very clearly the size of volume, adjusting elastic force or pressure that can be suitable, can correct a mistake, easy to use, easy and simple to handle.
Accompanying drawing explanation:
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the utility model structural representation;
