The utility model discloses a semitone harmonica with a muffler pressing a slightly noisy sound, including an intermediate lattice, an upper spring plate and an upper cover plate assembled sequentially above the lattice, a lower spring plate and a lower cover plate assembled sequentially below the lattice, and a muffler plate and a blow mouth assembled sequentially on the front side wall. The right end of the muffler plate is protruded with keys, and the right end of the lattice is internally provided with a spring piece connecting the muffler plate and pressing. The keyboard muffler displaces left and right between the piano lattice and the blowing mouth. The piano lattice is a resin or acrylic part. The upper and lower sides of the front side wall extend forward to form a slot along the edge, and the muffler is inserted into the slot. The utility model changes the slot of the inserting muffler board from the mouthpiece to the lattice, which makes the gap between the muffler board and the lattice smaller, has better air tightness, and reduces the difficulty of pronunciation caused by air leakage; and changes the three-sided metal friction between the original muffler board and the mouthpiece, and the sliding contact between the metal muffler board and the lattice made of resin or acrylic force, reduces the murmur caused by friction and makes the harmonica play. The sound quality is more pure.

变音板按压微噪音的半音阶口琴
本技术涉及乐器领域,更具体地说,它涉及一种变音板按压微噪音的半音阶口琴。
技术介绍
半音阶口琴由传统的口琴改良而来,利用一个巧妙的变音板按键可以在一支口琴上面吹奏出升降半音,因为其音域广,且便于移调或转调,近年推广迅速,经常运用于口琴合奏和多重奏中。半音阶口琴在琴格前侧壁依次组装变音板和吹口,其具体连接结构如图4所示,是在吹口后侧边设置卡槽,变音板穿插其中,再通过螺丝将吹口固定在琴格前侧的平口上。变音板与琴格之间气密性差,存有缝隙,导致吹奏时会漏气发音困难;同时由于变音板和吹口均为金属件,按压按键中变音板上边、下边、前侧三面与吹口都产生金属摩擦,产生一定的杂音,严重影响音质。
技术实现思路
针对现有技术存在的不足,本技术的目的在于提供一种解决上述问题的变音板按压微噪音的半音阶口琴,琴格上设置插槽与变音板连接,二者气密性好,不漏气,吹奏轻松,且减少变音板与金属件的摩擦接触面,摩擦噪声微弱,提升口琴吹奏音质。为实现上述目的,本技术提供了如下技术方案:变音板按压微噪音的半音阶口琴,包括位于中间的琴格,琴格上方依次组装的上簧板、上盖板,下方依次组装的下簧板、下盖板,前侧壁依次组装的变音板、吹口,所述变音板右端突出有按键,琴格右端内部设有弹簧件,弹簧件连接变音板,按压按键变音板在琴格与吹口之间左右位移,所述琴格为树脂件或亚克力件,其前侧壁上下边分别向前延伸出沿边形成插槽,变音板穿插在插槽中。变音板与琴格三面接触,气密性好,不漏气吹奏轻松,且仅前侧与金属吹口接触,杂音小,音质大大提升。本技术进一步改进技术方案是,所述琴格前侧壁上下边分别向前延伸出 ...
