Description
Background technology
The present invention relates to the signal processing unit field, the electric audio signal that described signal processing unit processes and operation are produced by the guitar that amplifies (amplifed guitar).More specifically, the present invention relates to comprise the signal processing unit that touches quick dynamic control unit, describedly touch quick dynamic control unit and be installed on the guitar when playing guitar, to control, to operate and to handle nearly three-dimensional sound effect parameters in real time and easily.
Although by using out-of-date analogue technique, electric guitar only allows variation sound music (for example, the conversion between tone, volume, the pickup) aspect the most basic, the electric guitar player needs to create unconfined a collection of musical sound really.Therefore, in order to improve sound, the guitarist gets used to adding various signal processor accessories between guitar and guitar amplifier, and these signal processor accessories are called as " effect device ", " stomp box effect device ", " pedal " or " multiple effect device ".
Comprise overload, distortion, fuzzy, compression, restriction, expansion, gating, Graphic equalizer in the long list of sound effects, chorus, move swiftly, phase shift, sound, pitch, phase-shifter, rotary loudspeaker, trill, rub sound, vibraphone, talk, carryover effects, Space and various types of simulate effects (it has realized the simulation of different preamplifiers, amplifier, guitar, audio amplifier, sound pick-up and stomp box effect device).These audios are great for the contribution of music industry.These audios and these audios in most modern popular music, have all occurred the style of music has been had tremendous influence.And, guitar audio even can create music style.For example, in the guitar musical sound, do not add distortion effect and just can not play out hard and heavy rock music style.
Signal processor also makes the guitarist imitate the sound (room, hall, operating room, park or the like) of dissimilar environment or the sound that simulation is produced by dissimilar amplifiers.By using the multiple effect device, the guitarist can imitate dissimilar audio amplifiers, guitar and stomp box effect device, and need not buy them, thereby has saved a large amount of money.Possibility in this field is unlimited.By the result of use device, the guitarist can create the more sound of wide region, and it adds dimension (dimension) in music, even therefore dull do not have the sound of inspiration can be dynamic immediately yet.
Give the credit to acoustic processing improvement technology and electronic miniaturization to a great extent, multiple effect device unit becomes modern guitarist's reliable and effective instrument.Modern electric guitar player contacts the technological progress of global music field and is subjected to the influence of this technological progress.Correspondingly, modern electric guitar player not only modesty has accepted new technology, and seeks and the feature that will look for novelty, new effect and more be rich in the sound of quality.
In order to make the electric guitar player can extract various sound and can perform flexibly as the musician in other field, the electric guitar player just need get caught up in the variation that electric guitar can provide or accept all the time.Therefore, carried out a large amount of trials in recent years, with exploitation audio algorithm and sound processing and control element (PCE) and in guitar self instrument of integrated computerization.
Signal processing unit (SPU) is audio or multiple effect signal processor.SPU receives two kinds of dissimilar signals at its input: audio signal and control signal.Audio signal receives from guitar, guitar sound pick-up or temporary location, and control signal receives from control module.The program of the expectation of selecting according to the user is handled by software algorithm or circuit then and is changed audio signal.This algorithm or circuit have variable parameter, and these parameters are according to changing from control signal static and that dynamic control unit receives.
SPU is controlled by a group selector statically, i.e. button and knob, these buttons and knob make the guitarist can edit the program of expectation before playing guitar, visit and are provided with various effect parameter, and select desired effects from effect banks when playing.
Yet, can know that these equipment that are used to change audio signal characteristics have some shortcomings or restriction.
For different effect parameter is set when playing guitar, the string that the musician must remove his hand guitar to be regulating the suitable knob or the dial of signal processing unit, and it is usually located on the bottom surface or in rack mount.Therefore, the musician just can not continue shoegaze in this time interval.The quantity that this has just caused the interruption of tune and the variable element that provides has been provided, thus the restriction guitarist changes and the relevant different parameters of handling of voice signal in real time.By using pedal to address this problem a little.
Device with pedal, for example pedal perhaps is integrated in the signal processing unit (SPU) or as its expansion and uses.Described device is dynamically controlled the guitarist and is changed Processing Algorithm, circuit and the parameter of the sound that produced thus.The guitarist is by with heel or knock pedal with tiptoe and control this parameter, thereby changes the value of parameter.
Yet device with pedal normally is fixedly located in a place, and this just needs the musician also to remain in identical place.In many music performances, the musician prefers strolling about before the lights, during with the change of the feature that realizes the audio signal that they are just producing, has just hindered them and has strolled about before the lights near they have to stay in pedal.Therefore, pedal has just limited his performance of moving and disperseed him by guitarist mobile being restricted to single fixing position when the control audio.
And in the performance, the device with pedal that is positioned on the stage floor can not be seen by spectators at the scene.This restriction has prevented that the guitarist from making up visual sound effect performance (for example " performance " that the guitarist uses the trill handle to carry out when performance) when playing guitar.
In addition, pedal devices restrict the guitarist control effect parameter independently more than one at every turn.This restriction is to controlled number of effects and consequent range of sounds have caused bigger constraint simultaneously.
And device with pedal will utilize complicated hand-foot coordination, therefore just is subjected to lacking the restriction of sensitivity and speed.
In addition, can only make the device with pedal activity by leg.The very big restriction that this has just caused for the guitarist who suffers this health problem hinders it to use leg to activate and the control signal processing unit during playing.
Carried out trial many times in recent years, control to be provided and to operate the signal processing unit of the effect of electric guitar.United States Patent (USP) 6,570,078 has proposed a kind of system that is used to generate control signal.Described system comprises and being used for by using the image processing to comprise the pixel data array that uses Trackpad to extract figure and directional information that it may have been installed and impact and/or pressure sensor.Although the configuration of Trackpad is referred as control module, prior art can not provide portable in the guitar that amplifies and signal processing unit movably, and can not make the guitarist control multiple audio device when playing guitar.

The relative position of three-dimensional Δ X-Δ Y-Δ Z sensor measurement finger of operation Δ X-Δ Y-Δ Z sensor in preset time, and Δ X represents the relative position of horizontal direction finger with respect to given reference point, Δ Y represents the vertical direction finger relative position about given reference point, and Δ Z represents to point on the DCU sensor relative pressure value with respect to reference value.
In case the contact that DCU detects finger with measure the required dimension of the different sound effect parameters of aforesaid control, the control signal that comprises this information just is transferred to SPU.User (passing through SCU) selects SPU audio program in advance.Therefore, according to the program of hope and the control signal that receives from DCU, SPU just handles by software algorithm and change guitar audio signal.
More particularly, SPU can start, stop and handling the sound of guitar generation according to contact and/or pressure and/or position and/or the time value of finger activated DCU.This can handle its finger and the sound of continuously or intermittently change guitar by continuously or intermittently with regard to making the guitarist on DCU.
Compare with existing traditional multitone effect system in the market, the present invention produces following major advantage.The first, system allows the guitarist to change nearly three effect parameter in real time at once, and described effect parameter is in three physical coordinates axle-X, Y, Z+W, and W represents the contact of a plurality of fingers of system responses to DCU.Therefore, the musician can create the more complete new sound of wide region, adds new dimension and tone color in its music, even creates the music style that makes new advances.For example, by using three-dimensional X-Y-Z touch-pad DCU, the guitarist can realize following achievement: vertically move its finger increase distortion gain effect parameter by stride across X-axis on Trackpad, flatly move its finger combination audio fruit by striding across Y-axis in the mobile mode that circulates, and by with its finger by on the Trackpad surface or discharge its finger and increase/reduce total volume.And these characteristics make the guitarist can carry out balance (for example, he can increase the size of distortion gain parameter and reduce the reverberation time delay parameter simultaneously) when playing guitar between at least two effect parameter.These new characteristics are very useful, in particularly performing at the scene.
The second, by using " contact-response mechanism ", this mechanism is to force value and the vibration sensing of finger activated DCU, and the guitarist can be more naturally and more passionately controlled multiple audio.For example, in three-dimensional X-Y-Z Trackpad, the guitarist can increase volume and sound duration by exerting pressure to Trackpad.In this case, the guitarist can be placed on its little finger of toe on the position of wishing on the Trackpad, can be by pushing, discharge or vibrating its little finger of toe and add entertaining in music when fingering a stringed instrument.
In addition, because hand is rapider than leg, the DCU that is activated by hand can control and the operating effect device guitarist with the toggle speed that increases.This ability can produce the controlled response time of SPU algorithm faster,, therefore and cause the better performance of the sound that produced.
And, because DCU and guitar string activate by same hand, so the present invention has avoided the needed hand-foot coordination of guitarist of use device with pedal.Therefore, the learning curve that has greatly shortened the player has also been saved to reaching the required plenty of time of training of identical performance level for it.
These characteristics have produced another advantage, although guitar and effect device all are to be activated by guitarist's hand, but the present invention provides the chance of using dynamic audio in it is played for the guitarist who suffers this health problem, and described physique problem hinders the guitarist to use leg activation effect device.
The present invention has introduced portable system, this system is fixed to makes the guitarist can freedom when playing guitar movable on the guitar anywhere, and dynamically operate multiple sound effect control unit by on the surface of multiple sound effect control unit, controlling hand in real time.These new characteristics are very useful, particularly on the stage of performing at the scene.
The present invention makes the guitarist remove this system from guitar, system is taken to him like Anywhere, and be fixed on another guitar.
And, DCU is fixed to allows the guitarist to perform the performance that visual sound is handled on the front panel of guitar, this is (be similar to guitarist in concert by using the trill handle to change guitar sound, using electrical drilling machine to play guitar, playing guitar after it, manipulating the strings, play solo while backward somersault and many other good " performance " " performance " that technology gave on trampoline with its tooth) by showing that to spectators it is realized by the mode of controlling DCU with hand and changing sound.Therefore, the guitarist can improve its performing quality and increase spectators' enjoyment.
Generally speaking, the present invention provides the chance that improves its music and performance achievement for the guitarist.It allow the guitarist to guitar play with music composition in add new only degree and creativity, this will greatly increase the enjoyment of playing guitar and happy.
Can further be embodied as built-in unit in dismountable unit, the guitar body according to DCU of the present invention.In addition, the parts of the system except DCU can or be placed as separate unit, perhaps are installed on the main body of guitar, perhaps are embodied as the built-in unit in the guitar body.
