Harmonica reed connection method

Abstract

The invention relates to a method for connecting harmonica reeds, which belongs to the technical field of musical instruments. It is characterized in that: the seat plate is made of stainless steel, and the spring cap of the reed and the seat plate are fixed by welding. The specific process steps are as follows: Punch the sound hole longitudinally on the seat plate; spread a long strip of kapok paper horizontally on the surface of the sound hole on the seat plate to cover or partially cover the sound hole on the seat plate, and leave the welding position for Lay the kapok paper; insert the reeds one by one into the sound hole on the kapok paper; paste a long strip of adhesive tape on the surface of the kapok paper embedded with the reeds; place the seat plate with the reeds directly on the point Weld at spring cap on welder; remove tape and kapok paper. The invention can not only ensure firm positioning between the reed and the seat plate, reduce the gap between the bottom sound hole and the reed, enable the sound to be pronounced by light blowing, but also reduce the material cost of the seat plate.

Description

Technical field: [0001] The invention relates to a harmonica, in particular to a method for connecting harmonica reeds. It belongs to the technical field of musical instruments. Background technique: [0002] A harmonica is a musical instrument with multiple reeds that vibrate to produce different tones as air passes over the various reed surfaces. There are 48 reeds on a harmonica, and 48 sound holes corresponding to the 48 reeds are opened on the seat plate, and each reed is located above or below the corresponding sound hole on the seat plate. The spring caps are all fixed to the seat plate by a rivet, and the other end is free to rest. This riveting mode of reed mainly has following deficiencies: [0003] 1. The positioning of the reed is not accurate. There is only a 6μm gap between the edge of the reed and the sound hole on the seat plate. The position of the reed is easy to move during the riveting process. After the reed moves, the pronunciation will be inaccurat...

AI Technical Summary

Problems solved by technology

There is only a 6μm gap between the edge of the reed and the sound hole on the seat plate. The position of the reed is easy to move during the riveting process. After the reed moves, the pronunciation will be inaccurate or produce strange sounds;

[0004] 2. There are many riveting processes

[0005] 3. Applicable materials are limited

If stainless steel is used as the seat plate in order to reduce costs, if the same riveting process is used, because the diameter of the riveting hole is only about 1mm, it is difficult to punch and form such a small hole on the stainless steel plate

For example, it is difficult to correct after the reed moves during riveting

But the pronunciation of the aluminum seat plate is not good
