Description

Multi-function digital violin

Technical field

The present invention relates to a violin, and more particularly to a multi-function digital violin having intelligent tuning, positioning, tuning, and the like. Background technique

The pitch of the violin has always been recognized as a major difficulty in the study of violin. First of all, the violin needs the learner or the performer to perform the operation of four empty strings before each use and during use, and for beginners. In general, the teacher or other professional is usually used to help complete the necessary empty string tuning; in addition, the violin's fingerboard is not marked with a pitch position itself, but by the player's left-handed tip. A device that produces its pitch (position) concept when it is struck to the surface of the fingerboard. The pitch position of each tone is actually present on the fingerboard, and the player presses the fingertips onto the fingerboard while playing. Accurate pitch position requires the player to obtain a high sensitivity from hearing to finger-to-sound response and a precise sense of position of the finger on the fingerboard after a long period of rigorous training, so that the performance can achieve a better pitch state. Everyone who knows music knows that the three fundamental elements of music are pitch, rhythm and music.

For a long time, students who have been practicing the piano for the wrong or inaccurate sounds that they did not realize often have to wait for a week or when they can go to the professional class to be pointed out by the teacher. At this time, the students are used to hearing. In the usual mistakes or inaccurate sounds, it takes a certain amount of time and effort to correct them. As everyone knows: "Any mistake (sound) has been made ten or more times, and it will be farther away from the correct target."

The current general situation is: The problem of the pitch of the beginners is that the teacher uses the strip tape on the violin's fingerboard to fix the sound and locate it, which is mainly based on the eye gaze and the touch of the fingertips. Students are fixed and positioned. This only partially and indirectly helps the concept of training pitch, but some do not. Instead, they develop a bad habit of "using the eyes without ear". This is not good for any string learner of violins. Because of this, a large number of professional teachers are firmly opposed to this common practice. The present invention is an effective way to truly replace this traditional practice, in order to establish a good habit of "using the ear" to train the pitch. Summary of the invention The object of the present invention is to provide a multifunctional digital violin which solves the difficulty of the above-mentioned violin learning process and plays an important role in helping to grasp the three elements of pitch, rhythm and music sense in music. It brings great convenience and fun to the piano and the piano.

In order to achieve the above object, the technical solution of the present invention is as follows:

A multifunctional digital violin comprising a body, a string, a neck, a string pillow, a bridge and a string box, etc., characterized in that: it further comprises a fingerboard, and the fingerboard is provided with the actual presence a plurality of planar phoneme sensing keys corresponding to the phonemes on the board; an electronic device is disposed in the fingerboard, and the electronic device comprises a plurality of sensors (inside) disposed under the plane phoneme sensing button, a control chip, and a a storage module storing standard audio; the sensor is connected to the control chip; when the control chip is in a normal uttered state, a sensing signal input of the planar phoneme sensing key, the sensing signal input by the sensor is in the Processing in the control chip and calling out the standard audio stored in the storage module, and issuing a standard audio sound that should be generated at the position by the control chip; when the control chip is in the tuning state, the natural piano sound of the violin performance is input to the Controlling the chip line processing, converting into an audio signal, and converting the audio signal converted by the control chip to the memory module Compare and quasi audio signal instructs a signal to remind the players.

The control chip includes a plurality of function control buttons connected thereto, the control buttons being mounted on the right side of the fingerboard.

The control chip includes an input module, an output module and a power module, the input module is connected to the sensor, and the output module outputs an indication signal.

The output module includes an interface. The interface is an audio output interface. The output module further includes an indicator light connected thereto, and the indicator light is disposed on both sides of the middle portion of the fingerboard. The output module also includes a pair of small speakers coupled thereto. The speaker is disposed at both ends of the lower edge of the fingerboard (or in the body of the violin).

The storage module includes an interface connected thereto. The interface can be a USB interface. The power module includes a control switch for controlling power on/off. The power module is a rechargeable miniature lithium battery. A USB interface or a power interface is further disposed on the power module.

The MIC of the lower end surface of the fingerboard is further provided with a MIC for recording/sound control input/audio sensing, and is connected with an input module of the electronic device.

Each of the phoneme sensing keys is a groove. The groove is the same size as the left finger At the time of contact with the fingerboard, there is a sensor inside.

The planar phoneme sensing button can also be a thin inductive patch, and the thin inductive patch is attached to the fingerboard, and the thin inductive patch is the same size as the fingerboard.

A film is disposed on the sensor.

The electronic device also includes an MP3 player. - The multifunctional digital violin of the present invention has the following functions:

1. Tuning function: The electronic device can emit standard audio of four empty strings (from coarse to fine) of the continuous violin through small speakers mounted on both sides of the lower end of the fingerboard: G, D, A, E. Its standard A audio and audio has 440-442Hz three audio options (other G, D, E audio automatically adjust accordingly with A audio and audio), and four empty strings are tuned according to the standard audio vocalization; It has the function of monitoring the four empty strings. The indicators are installed on the left and right sides of the middle of the fingerboard. When the control button is adjusted to the inductive monitoring function, the left and right indicators on the left and right sides of the fingerboard indicate that the pair is being proofread. The sound of the string is "low" or "high". When the indicator on the left is on, it indicates that the string is low. When the indicator on the right is on, the pitch is high. When the lights on both sides are off, When the flash alternates frequently, it indicates that the string reaches the standard pitch at this time.

2, fixed, positioning and tuning function: Selectively placed under the four strings on the fingerboard: ^ to G on the G string; # D to D on the D string; # on the A string AA; F to A on the E string and all 53 semi-tone and full-tone 53-sound-sound-sensing keys, and the position of these-sound-sensitive key positions is the pitch position on the actual fingerboard. The planar phoneme sensing key on the surface of the fingerboard is designed to be switched between visible and invisible. When the player is playing, the left hand 1, 2, 3, 4 fingertips touch the string and touch the plane phoneme sensor key on the fingerboard, the sensor under the plane phoneme sensor key is pressed, processed by the electronic device, refers to The speaker on the board is the standard audio that emits the tone (there are two types of pronunciation: one is continuation of standard audio; the other is a short standard audio), when the finger is raised, the flat tone sensor is below the key When the sensor disappears, the audio is turned off. At the same time, it can realize that when a fingertip is pressed to a sound, the sound position sensing key sounds and the sound of the previous sound level sensing key is turned off, so that the "preserving finger principle" when playing the violin is not affected. ; If it is a two-tone, two fingertips simultaneously press two tones, and the corresponding two phoneme sensing buttons sound at the same time. This function helps the learner to react quickly to the difference in the pitch of the performance and the standard sound during the practice - the fingertip is adjusted to the exact position of the sound following the standard audio; Can play a very good auxiliary role, can be easily replaced Practice to master the "position" of the violin's phoneme. The response to "acoustic" is a natural responsiveness inherent in each person's instincts. It is the most effective and fastest way to train people's high sensitivity to the pitch response from the "ear" to the fingertips. This also plays a role in tuning and positioning.

The 53 semitones and full-tone planar phoneme sensing keys on the fingerboard are controlled by control buttons or voice-activated switches to control the generation of each (tone) tonality. There are 13 major/t3 minor tune: C major /a minor, G major/e minor, D major/b minor, A major/liter f minor, E major/liter c minor, B major/liter g minor, F major/liter d minor , F major / d minor, B flat major / g minor, lower E major / c minor, lower A major / f minor, lower D major / lower b minor and lower G major / lower e minor. When the user sets the desired tonality in advance, the key sounds, other flat sounds when the left-hand finger presses the flat phoneme sense key of the tonality under the string (fingerboard) during performance. The bit sensing button is off. When the finger presses the wrong tone and the flat phoneme sensor key of the tonal voice is turned on, the button does not sound; when the user follows the temporary up sign or the down mark note shown in the score. When the correct phoneme is pressed, the tone key is also turned off because it is in the off state, which helps the learner to pull the wrong tone when practicing the piano, or to find the sound in time, so that Quickly grasp the tonal relationship of the tone and the correct position of the finger.

These planar phoneme sensing keys can also be provided with light and shadow invisible marks. When the tonality control keys are turned on and adjusted to the desired tonality, the planar phoneme sensing keys of each tone in the tonality can also be displayed by light and shadow. It allows the learner to have an intuitive visual impression of the position of the tonality within the tonality. These phoneme sensing keys can be used to emit standard audio of each tone through two speakers when the left hand finger is touched by the string, that is, standard audio can be issued without the piano and without the string. The digital violin itself can be used as a "finger keyboard" to practice the pitch and hand shape of the left hand; and to promote relaxation when practicing the shift position; and to use the built-in metronome function described below to view the practice score Playing will also help.

3. Metronome function: The metronome is an auxiliary tool that every piano learner must use during the piano practice. It can help the piano player to master the correct rhythm of the music. The built-in metronome of the multifunctional digital violin of the present invention emits "嘀" and "嘀" through two small speakers mounted on both sides of the lower end of the fingerboard.

The sound of "嘀"... or the beat (sound) is indicated by a silent form of staggered flashing lights on the left and right sides of the middle of the fingerboard. The rhythm of the metronome is adjusted from Lento to Presto by the “plus/minus” controls located on the side of the fingerboard.

4. MP3 function: The digital multi-function violin of the present invention also has MP3 functions: downloading, recording, playing and repeating (recital), recording and downloading the music, accompaniment track being learned, or by installing The recorder MIC in the middle part of the lower part of the fingerboard is self-recorded, and its repeating (playing) function can play a very good role in learning the piano, which makes it easier for the learner to gain the sense of music and improve the interest in learning the piano. schedule. There is also an audio output interface on the left side of the fingerboard, which allows the player to implement the Karaoke function, playing like "with a accompaniment piano or a big band". It is also easy to play with two speakers mounted on the sides of the lower end of the fingerboard.
