Abstract
The present invention relates to a temperament standard generator for piano, belongting to a domestic electronic instrument. When making temperament for piano, said invented temperament standard generator is used for detecting and indicating sound frequency corresponding to every key of piano tuned, and at the same time indicating standard sound frequency,and comparing the detected sound frequency with the standard sound frequency to make judgement of higher temperament or lower temperament and make presentation of that said string must be tensed or slackened. Said invention also can be used for tuning other music instruments.
Description
Temperament standard generator for piano of the present invention is a kind of electronic device, also is a kind of household electrical appliance.
When temperament standard generator for piano is used for piano tuning, the display standard voice frequency, detect simultaneously and show by the sound frequency of each key correspondence of the piano of adjustment musical note, compare with the standard pronunciation frequency, make musical note judgement higher or on the low side, and make and regulate the nervous or lax prompting of string.Temperament standard generator for piano can also send and standard pronunciation frequency corresponding simulating piano voice.
Temperament standard generator for piano of the present invention can be used as piano tuner's aid.The tuner mainly relied on the physiology sense of hearing and the sensitivity of musical note was regulated the musical note of calibrating piano in the past, made it the standard that is close to.Outstanding tuner has special ability in the physiology sense of hearing with aspect two of the sensitivities of musical note.Even but classic tuner also is difficult to accomplish to make the pairing musical note of each key of piano " absolute standard ".Temperament standard generator for piano of the present invention but can be easy to accomplish this point as precision electronic device.Because its " sense of hearing " and be only really classic to the resolution characteristic of musical note (audio frequency).
Rely on the auxiliary of temperament standard generator for piano of the present invention, the ordinary people also can carry out piano tuning work, and can meet or exceed " outstanding tuner " level by means of the physiology sense of hearing and musical note sensitivity.
Temperament standard generator for piano of the present invention can be used for other musical instrument of verification as being used for adjustment piano musical note, adopts corresponding sounding module, also can send the simulated sound of other musical instrument standard musical note.
The function of above-mentioned temperament standard generator for piano can permutation and combination be applied.For example, can only detect the frequency of each sound of musical instrument sounding, and compare with standard audio; Perhaps only detect the frequency number of each sound of musical instrument and the frequency number of display standard sound, the person compares voluntarily by the adjustment musical note.
The use object of estimating temperament standard generator for piano has: theatre troupes such as the sellers of the consumer of piano, piano fabricator, piano and other musical instrument, theater arenas, troupe have individual, family and other group of piano and other musical instrument.
Piano tuning calibrated generator of the present invention can with other piano tuning instrument, as special spanner etc., supportingly provide the consumer.Also can provide the consumer with the special-purpose tuning instrument of other musical instrument is supporting.
The principle of work of temperament standard generator for piano of the present invention is: use electronic technology such as existing electronic component of modern society and circuit, the sound that musical instruments such as piano are sent carries out pickup, then audio frequency is analyzed, calculated to each musical note, and compare with the standard frequency of the corresponding musical note of each key.Calibrated generator stores the standard frequency of each scale of music, musical note.Although the kind of musical instrument varies, the sound that is sent also has nothing in common with each other.The tonequality that various musical instrument is sounded depends on the waveform of its audio frequency and sound wave.But during their playing musics, the standard frequency of musical note is all determined.For example: 120 shaped steel qins have 88 keys, and the frequency of the pairing standard musical note of each key is fixed.
Temperament standard generator for piano is when sending the standard pronunciation of simulation piano, can adopt the principle of mellotron simulation piano sounding, promptly adopt the waveform of simulation of integrated circuit piano sound wave, send the frequency that certain determines musical note by frequency generator, both are combined into the electric wave electroacoustic source of certain waveform and certain frequency, send the sound of simulation piano by loudspeaker.
The another kind of method that temperament standard generator for piano sends the standard pronunciation of simulation piano is the frequency of regulating the corresponding musical note of each key of piano, make it identical with standard frequency, then that this frequency is identical with standard frequency qin sound is recorded, and stores in the temperament standard generator for piano.When needing sounding, the recording of determining is broadcasted with loudspeaker.
When temperament standard generator for piano is simulated the standard pronunciation of other musical instrument, can adopt above-mentioned two kinds of principles that method is identical.
The primary structure of temperament standard generator for piano of the present invention is: input-output device, memory device, comparator circuit, operation control circuit etc.
Input equipment has: acoustic pickup is transformed into electric signal with voice signal.Key sequence input equipment has two kinds, and a kind of is the enter key of simulation piano key; Another kind is a figure key, uses the sequence code name of figure key input piano key correspondence.Function selecting key etc.
Output device has: number and literal display, loudspeaker etc.
