Embodiment
Be described in further detail of the present invention below in conjunction with Fig. 1-9.
The mobile phone electroacoustic urheen of the present invention's design, is increase by two annexes removably on the basis of common urheen, is respectively mobile phone urheen connector 2 and adjustable exhaust box 3.Wherein, common urheen often comprises with lower component: qin cylinder 11, qin bar 12, string 13, peg 14, bridge 17, very heavy 15 and bow 16 etc., because urheen main body is prior art, do not repeat at this.Core of the present invention increases mobile phone urheen connector 2 and adjustable exhaust box 3 to adaptability in existing any a urheen main body.Mobile phone urheen connector 2 is located at outside the sound window 111 of qin cylinder 11, it is primarily of compositions such as acoustic pickup 21, mobile phone slot 23, mobile phone pressure pin 24 and audio output ports, wherein, sound window 111 is close to by acoustic pickup 21, be preferably the medium position of sound window 111, it is by the musical sound of catching urheen and sending and output to audio output port after being converted to electric signal.Conveniently be connected with mobile phone and facilitate and play, mobile phone slot 23 is arranged on the opposed side of acoustic pickup 21, and headset plug 231 connects with the earpiece holes of mobile phone.Fig. 9 is shown in by the circuit diagram of mobile phone urheen connector 2, acoustic pickup T picks up the software of urheen sound on mobile phone and carries out audio tuning, and output to audio output port, its audio output port is set to two usually, one is monitoring headpone jack 221, it is connected with monitoring headpone, for player oneself; Another port is external output jack 222, and it is connected with stereo set, can set up potentiometer R2 for the volume of regulation output to sound-box device in this circuit.Monitoring headpone jack 221 and external output jack 222 are two-channel jack.
Volume can be adjusted to very little thus avoid interference surrounding population to realize player when practicing qin, the present invention arranges adjustable exhaust box 3 at qin skin 112 end of qin cylinder 11, it mainly comprises bracing frame 32, the pressing plate 31 vertical with bracing frame, adjusting knob 33, pad 37 and bridge hovering card 36 etc. are stablized in bridge hovering, being realized by the pressure changing bridge 17 pairs of qin skins 112 of volume, it is specially: in the hole of bridge 17 central authorities, through a pulling item 41, the middle part of pulling item is the bridge bridge 17Q of bridge 17, two ends arrange pilot pin 42 respectively, pilot pin 42 is fastened on pulling item hook 35 removably, pulling item 41 after connection is shown as U-shaped, regulate pulling item to link up with 35 by adjusting knob 33 to move up and down, and then control the pressure of bridge 17 pairs of qin skins 112, realize the adjustment to volume, after installing, bridge hovering is stablized pad 37 and is fitted tightly with bridge bridge 17Q, in order to improve tonequality further, reduce the noise that urheen sends, the one side that described pressing plate 31 contacts with qin skin 112 is provided with cushion blocking 311, cushion blocking 311 is symmetrical two pieces, its size and two-stringed piano drum 11 match, edge just with qin cylinder 11 coincident, which reduce the acting force of qin skin 112 pairs of qin cylinders 11, and the shockproofness of equilibrium between qin skin 112 and cushion blocking 311, thus the tonequality sent after making qin skin 112 resonate is better, the material that cushion blocking 311 is generally certain sound absorbing power is made, be preferably the materials such as asbestos, the skin of cushion blocking 311 is donkey hide or cloth.
In addition, stable firmly bridge during in order to make to be in floating state, be provided with cushion pad 44 in pulling item 41 and bridge 17 joint, its material is preferably rubber peel, pulling item 41 is preferably also provided with lasso 43 between two ends, and pulling item 41 and pulling item can be linked up with 35 and firmly be connected by better.Good improvement is had to tonequality when the material of pulling item 41 is the rubber strip accompanying linen thread.The pressing plate lower end of adjustable exhaust box 3 arranges fixing feet 34 respectively, and it is for being more firmly connected with urheen.
When not drawing for a long time, in order to protect qin skin 112, adjusting knob 33 outwards can be lifted the card 36 that simultaneously hovered by bridge and pushing left side to, making bridge 17 be in floating state (now bridge and film are discontiguous); When deployed, right side pushed to by the card 36 that hovered by bridge, and adjusting knob 33 controls volume, when adjusting knob 33 rotates clockwise, pulling item 41 is strained, and the pressure of bridge 17 pairs of qin skins 112 is reduced, the volume that now urheen sends just reduces, otherwise volume increases.Meanwhile, be a kind of process of transfer of pressure when adjusting knob 33 rotates, namely when clockwise direction rotates, pressure is transferred on pressing plate 31 and cushion blocking 311 from bridge 17 gradually.Cushion blocking 311 serves following effect, one is that itself and qin skin 112 contact area are large, more effective to elimination empty sound, wolf sound, two is its adjustabilitys, when adjusting knob 33 rotates clockwise, the pressure of bridge 17 pairs of qin skins 112 reduces, and at this moment the pressure of cushion blocking 311 pairs of qin skins 112 just increases, such urheen sound just more real, more moisten.
During operation, according to the following steps:
1, pull out " mobile phone pressure pin ", " handset port " that " mobile phone urheen connector " is inserted in smart mobile phone (this example uses iPhone4) upper end is buckled " mobile phone pressure pin " again;
2, open cell phone software (as selecting " sounds of nature K sings "), select " K song "-" requesting song "-" mobile phone accompaniment " (to load sample etude) or select " singing opera arias ";
3 if practice qin at ordinary times, as long as by " earphone " insertion " monitoring headpone jack ".If performance, be connected with stereo set by " external output jack " with connecting line, regulate suitable output volume simultaneously;
4, " bridge hovering card " is pushed to right side, can start to practice qin or performance." bridge hovering card " will be pushed to left side (wanting pull-up " adjusting knob " to push away again) when urheen does not temporarily draw, " bridge hovering card " is in order to protect qin skin to design;
If volume and tone color that 5 will adjust the former sound of urheen, " adjusting knob " of rotatable " adjustable exhaust box ".In general, at ordinary times practice qin time volume is adjusted as small as possible, to reach the object of " not disturbing residents ", perform time to be as the criterion with tone color, tone color is transferred to optimum condition;
The state that 6, tone color will be made to reach more desirable, can in the enterprising Row sum-equal matrix of mobile phone and polishing, concrete operations are as follows: click " audio "-" self-defined ", on " balance " page, the lifting of adjustable characteristic frequency or damping capacity, and corresponding Q value (have 4 Frequency points adjustable).On " reverberation " page, adjustable " reverberation ", " psychrometric ratio ", " gain " etc.Adjust rear click " complete " and saved as " self-defined audio " (can store 3 " self-defined audios ");
7, in performance, click " audio " volume of performance and the volume of sound accompaniment (sample is bent) can be regulated at any time;
8, also can carry out recording on mobile phone, make MV, with the operation such as online friend's exchange and interdynamic.
