Summary of the invention

It is large, simple and honest that the purpose of this utility model is to provide a kind of whistling, and tone is accurate, is applicable to the flute with echo effect that various crowd uses.

The technical scheme that the utility model adopts is: a kind of flute with echo effect, be divided into three joints, flute head to flute brain is first segment, flute brain to middle interconnecting piece is second section, middle interconnecting piece to flute tail is Section three, it is characterized in that: described first segment is changed to diameter, the echo cylinder that length is identical with it, wherein, echo cylinder is metal-coating, built-in by loudspeaker, sound card wiring board, switch, microphone, the talk-back circuit of rechargeable battery composition, the metal-coating at microphone place has recording aperture, echo cylinder and second section are for being threaded, second section is bamboo trunk, section three, change hard north pipe into.

The utility model echo cylinder is also provided with charge port, convenient charging.

For thousands of years, people are by countless practice, and discovery only has the vibration of bamboo trunk well, and whistling tone color is clear and melodious, bright, so think that whole Zhi Zhudi uses bamboo trunk by mistake.The application is by understanding bamboo flute principle of sound, and whistling energy all derives from the vibration of air-flow in aperture blowing, the vibrating effect that one's intention as revealed in what one says air-flow and aperture blowing inner tubal wall, inside pipe wall collide, and determines whistling tone color.So the utility model is when second section still selects bamboo trunk, Section three changes hard north pipe into, at all can not affect whistling tone color, and strictly can press customization simultaneously in batch and produce, perforate is easy, not easily breaking, without the need to twining silk, and effectively can ensure accuracy in pitch.

The application is cork absorbing material for the flute plug of existing bamboo flute, when Seasonal Temperature Difference is larger, affects accuracy in pitch, significantly need move flute plug tuning standard, easily produce noise.Di Sai is generally suitable with 5mm apart from aperture blowing edge, and the application inlays upper metal interface cork flute plug one side, and like this in summer, whistling tone is higher, flute plug metal interface; In winter, whistling tone is on the low side, and cork interface used by flute plug, and the impact of change on bamboo flute frequency of natural vibration of can regulating the climate, avoids significantly moving flute plug.

The problem that the application brings for the aperture blowing of existing bamboo flute: as whistling not quite, not simple and honest, and the little difficulty of spray angle tolerance band is grasped, the difficulty to flute subband.Both sides tube wall in aperture blowing is inwardly repaiied tiltedly by the application, and the angle that slopes inwardly is about 45 degree, converges with inside pipe wall radian.The benefit brought like this has: on the one hand, and the whistling of acquisition is large and simple and honest, owes sufficient people bring very large benefit to tolerance; On the other hand, the tolerance band of spray angle expands, and when playing the flute, spray angle is easy to grasp.Aperture blowing should not be opened too much simultaneously, avoid the energy of Gas Vibration in aperture blowing too much to aperture blowing external diffusion, avoid aperture blowing outwards to propagate excessive airflow noise, avoid therefore and the whistling that causes reduces, facts have proved that the flute unification of the not people having the same aspiration and interest is the most suitable with diameter 8.5 × 9.5mm.

The application for existing bamboo flute over-blowing high pitch to 2 (), 3 () two sound time, bamboo membrane just starts not vibrated, and causes high pitch unclarity simple and honest, very dull; And the sound that sound hole sends is large not, the whistling that such tolerance owes sufficient people's blowout is little.The application inwardly repaiies tiltedly about 45 degree both sides tube wall in fenestra, sound hole, bamboo membrane can be allowed to vibrate, make high pitch bright simple and honest during over-blowing high pitch, not dull; Sound hole can be allowed to increase gas of dishing out, increase whistling.

Fundamental tone hole for existing bamboo flute is the same with sound hole large, causes the first hole, the pronunciation in fundamental tone hole easily occurs audio mixing, modify tone spoiled.The application opens large 1mm the diameter in fundamental tone hole than the diameter of sound hole, and repaiies tiltedly by both sides tube wall in fundamental tone hole to inner height, and degree of tilt is greater than 45 degree and is less than 60 degree, can effectively ensure the first hole, fundamental tone hole pronunciation invariable tone spoiled.

The sound hole that helps for existing bamboo flute only has two, causes whistling bass not bery simple and honest, easily occurs audio mixing, modify tone spoiled time pronunciation in fundamental tone hole.The sound hole that helps of the application is three holes, and whistling bass can be made to become simpler and more honest, fundamental tone hole can be helped to pronounce smoothly simultaneously, not occur audio mixing.

Because the flute inside pipe wall of existing bamboo flute is more smooth, what have has even also brushed smooth paint, causes fundamental tone line length to lengthen, and is difficult to blowout 5 () 6 () two high pitchs, and it is an indignant thought for mistake that visible flute pipe wants smooth.The application allows flute pipe inside keep to a certain degree degree of roughness, such as can to polish inside pipe wall, or at inside pipe wall brushing sand paint etc., allow degree of roughness as the surface of common whetstone, whistling tone color can not be affected, can shorten the length of fundamental tone line, shorten the length of each sound hole air column, over-blowing high pitch is not hard simultaneously.

First segment is changed to diameter, length echo cylinder identical with it by the utility model, and Section three changes hard north pipe into, thus it is large, simple and honest to have the whistling sent, and tone is advantage accurately, and has echo effect, is applicable to various crowd and uses.
