Description

Novel electronic percussion instrument

Technical Field

The utility model belongs to an electronic percussion instrument, in particular to an electronic percussion instrument which can be flexibly moved for performing.

Background

At present, percussion music is divided into two categories of traditional percussion instruments and electronic percussion instruments according to the sounding principle. The traditional percussion instrument uses hands or drumsticks to hit a certain part of the instrument itself, so that the relevant part of the instrument itself produces physical vibration to produce sound, or uses a resonance cavity with a certain shape and size to produce sound. The electronic percussion instrument is characterized in that sound generated by external force striking of the traditional percussion instrument is electronically sampled or recorded, and then is subjected to post-synthesis processing and then is stored in a specific sound source chip. When the striking surface of the electronic percussion instrument is also called as a drum disc, the sensor on the drum disc generates a force electric signal and a tone triggering signal corresponding to the striking force by sensing the striking force, the force electric signal is transmitted to a sound source through a wire, and simultaneously, the corresponding sampling tone in the sound source is triggered, then the corresponding transmission interface outputs the percussion music sound signal with the volume corresponding to the force, and the sound which can be heard by human ears is played from the sound box after the signal is amplified by the amplifier.

In the case of the percussion instruments known at present, whether traditional percussion instruments or electronic percussion instruments, the majority of the performance forms are performed by a musician sitting on a fixed seat with a drumstick, and there are also individual forms of percussion instruments where the musician stands on a fixed position to perform. Few percussion instruments capable of moving to perform are in the form of moving performance during performance, even percussion instruments capable of moving to perform are in the form of moving performance during performance, and combined percussion instruments such as the drum stand cannot be moved to perform at all. Especially, the percussion performance of modern electroacoustic bands is limited by the great potential of drummers because most of the drummers can only sit at fixed positions to perform due to complex musical instrument structure and can not freely move on stages to perform like playing a guitar, and the drummers can play in the foreground completely as the leading guitar and can play as the core of the whole band as the leading guitar player plays as the leading guitar.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to fig. 1 to 10 of the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The utility model provides a novel electron percussion instrument, the utility model discloses a drum disc of two kinds of sizes, the adoption small area conducting resin 67 drum disc of two contact carbon films, the adoption large tracts of land drum disc of multicontact carbon film, its used sound source is the same with the electronic organ sound source, only the memory tone quality is for percussion instrument entirely, general condition all can have dozens of sets of acquiescence settings, also reserve simultaneously and have panel memory function, can let the player oneself set up the back storage in the panel function memory button of sound source function box 02, can a key during the use be called out, in addition, can also store some classic rhythms in the sound source and supply beginner's exercise and appreciation as demonstration song, also can regard as MIDI equipment according to the function of sound source, through MIDI or other music equipment that have the MIDI function of USB interface control or carry out computer MIDI recording. The above-mentioned function has all generally adopted to present sound source programmer, at this moment the utility model discloses only can match with any suitable percussion instrument sound source as the input instrument of an electron percussion instrument, just like the standard keyboard of electron musical instrument, the sound source mainboard is direct mount in the cavity in the middle of headstock wooden body 08 under the general condition, or installs on the pole top, or two position cooperations installation.

The drum disc adopts two ways of acquiring force signals, one is a piezoelectric ceramic piece, and the other is conductive adhesive 67 with force. The application of the piezoelectric ceramic piece to the electronic percussion instrument is the most popular and mature now, and the force conductive adhesive 67 is rarely used. The force conductive adhesive 67 is divided into two types, one type is the conductive adhesive 67 with only one height difference of carbon film contacts, namely the conductive adhesive 67 with two contact carbon films, when a finger strikes the drum, a force signal is obtained through the time difference of the contact of the two carbon film contacts with the two corresponding plane carbon film contacts on the circuit board 63, the other type is the main body of the drum made of soft rubber, then a plurality of carbon film contacts with height differences are pasted on the lower surface of the inner part, one carbon film contact is positioned at the center of the circle of the drum, the lowest position is also called a low-point carbon film, the carbon film contact is finally contacted with the corresponding plane carbon film contact on the circuit board 63 to be conducted when playing, the rest carbon film contacts are distributed around the center of the circle and are higher than the center of the circle by a certain height difference, the carbon film contacts are contacted with the plane carbon film on the circuit board 63 before the center of the low-point carbon film contacts are played, so that the required force signal is obtained, because evenly distributed is the carbon film of another height of a plurality of or a plurality of height around the low point carbon film contact of centre of a circle, when the player beats the different positions of drum dish, the circuit board 63 plane carbon film contact that switches on is also different to can acquire several dynamics signals and trigger a plurality of tone quality signals simultaneously under once beating, this has just provided the structural foundation for the position simulation of percussion instrument tone quality, the utility model discloses a right hand drum dish all uses this kind of multicontact carbon film basically, because the contact is so that the drum dish area is also a little bigger. The aim of this is to take into account that the synthesis of timbre becomes more and more elaborate with the development of modern digital sound source technology, which provides a good solution for simulating traditional percussion music.

The utility model discloses because first drum dish group mainly is right-hand drum dish, the area can be done bigger than big, this just provides the physical space of reality for setting up of multicontact carbon film. For example, the drum tone can be subjected to multi-layer sampling of the strength through the strength change during sampling and synthesis, the position sampling can be performed through knocking different positions of a musical instrument, and then the tone obtained through sampling corresponds to the contacts at the corresponding positions of the drum disc through programming, so that the tone can be changed like the traditional musical instrument when fingers knock different positions of the drum disc, a new synthesized tone can be generated if a plurality of contacts are simultaneously conducted, the maximum simultaneous tone generation number of the existing sound source is basically more than 32, and some sound sources reach 512 maximum simultaneous tone generation numbers, so that a reliable sound source technical guarantee is provided for the application of the multi-contact conductive adhesive 67, and the sound source is closer to the traditional percussion instrument. The advantage of the multi-contact carbon film drum is that the piezoelectric ceramic drum is difficult to have, and the structure is also suitable for a drum which uses piezoelectric ceramic pieces to pick up force signals, but the piezoelectric ceramic piece drum is not suitable for being arranged in a too dense piezoelectric ceramic manner due to the driving effect caused by adjacent pressure.
