Description

A kind of soft pedal with gear aperture member

Technical field

The utility model belongs to Piano Fittings technical field, and in particular to a kind of soft pedal with gear aperture member.

Background technique

The utilization of soft pedal is very extensive, and can the step on pianist of pedal of any one foot must use it. Generally there are three pedals for piano.

The pedal on the right is " Sustain ", and for extending the time of string vibration, being exactly in fact will be originally tight with lever One layer of felt being attached on string is got out, to extend the time of string vibration.It can be said that this is in Sustain technology Origin, all technologies related with tenuto are all to dissolve to come from " cutting pedal ".

Middle pedal being referred to as most often " extends sound pedal ".In most of advanced grand pianos and some best in quality Upright piano on, middle pedal be referred to as selection Sustain, pedal is specially designed for pianist in this, it can make to hit One piece of heavy fleece lowers above string machine, keeps off between hammer and string, the sound that such pop-up is come with regard to it is small must only have oneself listen See, the people outside room does not hear then, this is in order to not influence others.

Left-hand tread plate is off beat pedal on general Household vertical piano, steps on left-hand tread plate, and hammer entirely moves forward, from The distance of string just shortens, and sound is accordingly just weak.So " string " is indicated on music score sometimes or " three strings " are exactly table Show with left-hand tread plate formula it is to decontrol left-hand tread plate.

And usually require setting at soft pedal and step on hole accordingly, especially in upright piano, piano procurement price is very Valuableness, the qin room in music school, due to usually unoccupied, especially in summer, the plague of rats takes place frequently, when mouse enters qin room Later, be easy to enter inside piano from the hole by soft pedal, piano mostly uses greatly wooden structures again, it is easy stung by mouse it is bad, The pedal holes of especially upright piano are larger and straight-through qin case, and mouse, which is easy to enter in qin body from pedal holes, does nest, stings bad steel Qin interior fittings, and qin master removes and does not facilitate method preferably with other hard object blockings with hole size.

Currently, piano pedal hole is primarily present following problems:

1, since the position for stepping on hole is lower, mouse is easy to damage piano from stepping on inside the drilling piano of hole.

2, since piano is inconvenient to dismount, mouse bad processing after entering.

3, it is partially blocked using hard object to stepping on hole, to stepping on after hole blocks, can loosen fall frequent occurrence, so that not It can prevent the destruction of mouse from causing well airtight inside piano, and hard object blocks so that being easy inside piano mouldy.

Utility model content
