Abstract

The utility model discloses a sound calibrating device, which comprises a singlechip control unit, a display unit, a functional-key operating circuit and an operational amplification/processing circuit and also comprises a memory, a sound recording circuit, a power amplification circuit and a loudspeaker, wherein the memory, the sound recording circuit, the power amplification circuit and the loudspeaker are sequentially connected, and the sound recording circuit is respectively connected with the singlechip control unit and the operational amplification/processing circuit. The sound recording circuit is additionally arranged on the structural basis of a traditional sound calibrating device, thereby the utility model realizes the function of sound recording, facilitates a user to record the played music while play or learn a musical instrument for later-stage arrangement and analysis, provides a greater help for rapidly enhancing the own playing level of the user and also can help the user to record the extemporaneously played beautiful music.

Description

A kind of CALIBRATION

Technical field

The utility model relates to the electro-acoustic device, relates in particular to a kind of CALIBRATION.

Background technology

In the musical instrument learning process, the accuracy in pitch of musical instrument is very important, if the sound of musical instrument is inaccurate, can influences the music-learner to the judgement of pitch and influence hearing, and can influence playing effect, destroy the music musicality, thereby the destruction music-learner is to the learning interest of music.So before playing an instrument, the user must carry out tuner to the musical instrument of learning or play with CALIBRATION.CALIBRATION function ratio in the market is more single, only has the tuner function, does not possess sound-recording function; Yet, the user is when shoegaze, may need to judge the accuracy of playing by the melody of playing before the audition repeatedly, perhaps in tuner, hope can be recorded some impromptu beautiful music score of playing, thereby be necessary to propose a kind of multi-functional CALIBRATION, satisfy user's user demand.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of CALIBRATION with sound-recording function, make things convenient for the music-learner play or the process of study in carry out melody and record, for finishing analysis in the future.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of CALIBRATION, comprise Single-chip Controlling unit and coupled display unit, function button function circuit, computing amplification/treatment circuit, also comprise the storer, recording circuit, power amplification circuit and the loudspeaker that connect successively, and described recording circuit is connected respectively with computing amplification/treatment circuit with the Single-chip Controlling unit.

Wherein, described storer is the flash memory module.

Wherein, also comprise power circuit, this power circuit is connected respectively with described Single-chip Controlling unit, display unit, function button function circuit, computing amplification/treatment circuit, recording circuit.

Wherein, also comprising microphone or circuit input block, this microphone or circuit input block amplify with described computing/and treatment circuit is connected.

The beneficial effects of the utility model are:

The utility model has been set up recording circuit on the architecture basics of existing CALIBRATION, realized sound-recording function, make things convenient for the user playing or recording during learning instrument the melody of being played, for the later stage finishing analysis, for the level of playing of user's fast lifting oneself provides bigger help, also can help the impromptu beautiful melody of playing under the user record.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the theory diagram of CALIBRATION among the utility model embodiment.

Embodiment

See also Fig. 1, the utility model CALIBRATION comprises following ingredient: Single-chip Controlling unit, display unit, function button function circuit, computing amplification/treatment circuit, microphone or circuit input block, also comprise the storer, recording circuit, power amplification circuit and the loudspeaker that connect successively, and recording circuit is connected respectively with computing amplification/treatment circuit with the Single-chip Controlling unit.Wherein, storer is the flash memory module.

The course of work of this CALIBRATION is: at first, open the sound-recording function of CALIBRATION by the function button operation; Then, play in the process the user, the musical instrument sound that play the outside is picked up by microphone or inputs to CALIBRATION by the circuit input block, voice signal is earlier after microphone or circuit input block change electric signal into, after computing amplification/processing circuit processes, be sent to recording circuit and Single-chip Controlling unit more respectively, by storing after the recording circuit encoding process, carry out tuner by the single-chip microcomputer processing unit and handle; After playing end, the user can operate by function button and select to play the musical instrument sound of being stored, and Single-chip Controlling unit controls recording circuit carries out the playback of sound by power amplification circuit and loudspeaker after extracting digital signal corresponding and it is reduced into voice signal from storer.

Because the utility model possesses sound-recording function, the user can carry out following application:

In the shoegaze process, can record and store playing melody, after playing repeatedly audition to judge whether to play accurately; Like this, the music-learner can identify the place of playing error rapidly and accurately and in time correct, and then improve apace and play level, avoided present beginner to suffer from and learnt shoegaze and do not know to play whether accurately puzzlement, improved beginner's learning interest;

In tuner, can record some impromptu melodies of playing, write down these beautiful moments; Like this, make the user can inerrably note the inspiration of oneself, so that the arrangement of playback in the future.

Above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, only with reference to preferred embodiment the utility model is had been described in detail.Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical solution of the utility model, and do not break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
