Fig. 1-8 is please referred to, the utility model provides a kind of technical solution: a kind of low noise urheen sound pick-up, including urheen Barrel 1, surface 2, rubber layer 3, pickup housing 4, groove 5, the first connecting plate 6, connecting rod 7, sound pick-up fixed block 8, limit Bar 9, the first fixed block 11, convex block 12, fixed rope 13, round bar 1301, the second connecting plate 1302, resilient strip 1303, picks up spring 10 Paste connection in the top of sound head 14, hose 15, microphone amplifier 16, microphone link block 17 and microphone fixed block 18, two-stringed piano drum 1 There is surface 2, and the top of surface 2 is placed with rubber layer 3, rubber layer 3, which is pasted, to be connected in the middle part of the lower surface of pickup housing 4, And the upper surface of pickup housing 4 reserves fluted 5, pastes at left and right sides of the lower surface of rubber layer 3 and is connected with the first connection Plate 6, and the underside of the first connecting plate 6 is connected with connecting rod 7, connecting rod 7, which runs through, to be connected on sound pick-up fixed block 8, and The upper surface outer of sound pick-up fixed block 8 is fixedly connected with gag lever post 9, and gag lever post 9 is through being connected to the first connecting plate 6 On, sound pick-up fixed block 8 is fixedly connected with the first fixed block 11 by spring 10 close to the side of two-stringed piano drum 1, and first is solid Determine block 11 to fit closely with two-stringed piano drum 1, and the lower section of the first fixed block 11 is fixedly connected with convex block 12, two-stringed piano drum 1 is left The rear side of the sound pick-up fixed block 8 of side is fixedly connected with fixed rope 13, and sound pick-up fixed block 8 of the fixed rope 13 far from left side Side be movably connected on the sound pick-up fixed block 8 on right side, the front side of the sound pick-up fixed block 8 on the right side of two-stringed piano drum 1 is fixed It is connected with fixed rope 13, and the side of sound pick-up fixed block 8 of the fixed rope 13 far from right side is movably connected in the pickup in left side On device fixed block 8, the inside center position of pickup housing 4 is equipped with pick-up head 14, and the left side of pickup housing 4 pass through it is soft Pipe 15 is fixedly connected with microphone amplifier 16, and microphone amplifier 16 and pick-up head 14 are electrically connected, and the outside of hose 15 is living It is dynamic to be connected with microphone link block 17, and the right side of microphone link block 17 is fixedly connected with microphone fixed block 18, and microphone is fixed Block 18 is fitted closely with two-stringed piano drum 1, and the rear side of microphone link block 17 is fixedly connected with fixed rope 13, and the fixed rope 13 is another Side is movably connected in the front end of microphone link block 17.

As the first connecting plate 6 constitutes rotational structure in connecting rod 7 in Fig. 5, and connecting rod 7 is adopted with sound pick-up fixed block 8 The mode being threadedly coupled is connected, then can be adjusted by rotation connection bar 7 sound pick-up fixed block 8 and the first connecting plate 6 it Between position, thus have the function that control rubber layer 3 whether be connected with surface 2；

If the cross section of the first fixed block 11 in Fig. 3 and Fig. 6 is in arc line shaped close to the side of two-stringed piano drum 1, and first is solid Determine block 11 and be symmetrically arranged with 2 about the vertical central axes of two-stringed piano drum 1, then can increase the first fixed block 11 and two-stringed piano drum 1 Contact area, to keep connection more firm；

As fixed rope 13 includes round bar 1301, the second connecting plate 1302 and resilient strip 1303, the rear side of round bar 1301 in Fig. 7 It is fixedly connected with the second connecting plate 1302, the rear side stickup of the second connecting plate 1302 is connected with resilient strip 1303, such as round bar in Fig. 7 1301 cross-sectional shape is rounded, and the diameter dimension of round bar 1301 is greater than the thickness of the second connecting plate 1302, then may be used So that the connection of round bar 1301 and microphone link block 17 and sound pick-up fixed block 8 is more convenient, it can also be with round bar 1301 due to bullet The elastic reaction of power item 1303 is fallen from microphone link block 17 and sound pick-up fixed block 8, as microphone connects in Fig. 1, Fig. 4 and Fig. 6 It connects block 17 and constitutes slide construction on hose 15, and microphone link block 17 and sound pick-up fixed block 8 are with round bar 1301 using card The mode of slot connection is connected, then can increase stability when microphone link block 17 and the installation of sound pick-up fixed block 8.

Working principle: when using the low noise urheen sound pick-up, first will by convex block 12 by the first fixed block 11 to The pressing of 8 direction of sound pick-up fixed block, the left and right sides that 2 sound pick-up fixed blocks 8 are then individually positioned in two-stringed piano drum 1 are backward Lower movement, fits closely rubber layer 3 with surface 2, then decontrols convex block 12, and the first fixed block 11 will pass through the elasticity of spring 10 It acts on mobile to 1 direction of two-stringed piano drum, fits closely the first fixed block 11 with two-stringed piano drum 1, it can will be at the beginning of pickup housing 4 Step is fixed on two-stringed piano drum 1, and rubber layer 3 keeps the placement of pickup housing 4 more stable, and plays protection surface 2 2 round bars 1301, are then inserted into 2 sound pick-up fixed blocks 8 by effect respectively, then decontrol round bar 1301, and round bar 1301 will It, can be firmly by sound pick-up since the first fixed block 11 is securely connect by the elastic reaction of resilient strip 1303 with two-stringed piano drum 1 Shell 4 is fixedly secured on two-stringed piano drum 1, and then string is placed in groove 5, then will be due to rubber layer 3 and sound pick-up outside The sum of height dimension of shell 4 is equal to the height of bridge, and pickup housing 4 has propped up string separation surface 2, reduced vibration, greatly Width, which reduces, plays volume, is then adjusted microphone amplifier 16 to the lower section of two-stringed piano drum 1 by hose 15 and is suitble to position, then After microphone link block 17 is slid into proper site on hose 15, microphone fixed block 18 and two-stringed piano drum 1 are fitted closely, so The round bar 1301 on microphone fixed block 18 is connect with 17 front side card slot of microphone link block afterwards, it can be by 16 position of microphone amplifier It is fixed, and since the diameter dimension of round bar 1301 is greater than the thickness of the second connecting plate 1302, and resilient strip 1303 has Elastic reaction then increases stability when round bar 1301 is connect with microphone link block 17, and do not use or when practice when not When wanting to have an impact others, can rotate and be threadedly coupled connecting rod 7 with sound pick-up fixed block 8, when the first connecting plate 6 limiting It is slided on bar 9, props up string far from bridge, then surface 2 will not shake sounding, and pick-up head 14 electrically connects with microphone amplifier 16 It connects, and pick-up head 14 is located at the inside of pickup housing 4, and pickup housing 4 is wood quality, then can almost ignore External any noise effect, reaches high signal-to-noise ratio, here it is the whole process that low noise urheen sound pick-up uses.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
