Problems solved by technology

The quality of the panel of the violin plays a key role in the sound and volume of the violin. During the production process of the violin, the violin cannot be pronounced before the panel of the violin is installed. The evaluation of its quality can only rely on the feeling of the technician. chance of mistakes, and once a panel with poor pronunciation is installed on the body, it will cause irreparable quality defects. Therefore, it is very critical for the staff to select a good panel. In addition, the violin panel will gradually deteriorate over time. How can a violin made of new materials have the sound of an old violin without being aged?

Embodiment Construction

[0019] The invention provides a method for detecting and debugging a violin panel, which comprises the following steps:

[0020] (1) Place the front panel and the back panel of the violin panel in groups, place the concave surface upwards respectively, and place 80-100 mesh fine wood inspection powder in the concave surface (it is best to evenly spread one-third of the panel area).

[0021] (2) Place the front panel and the back panel sprinkled with fine wood detection powder in the first vibration area. The vibration detection method of the front panel is: first adjust the frequency to 78Hz, and then gradually increase the frequency until 95Hz to observe and record the fine wood detection Powder distribution; the back panel vibration detection method is: first adjust the frequency to 110Hz, and then gradually increase the frequency until 120Hz to observe and record the fine wood detection powder distribution.

[0022] (3) Place the front panel and back panel sprinkled with fi...

Abstract

The invention provides a method and a device for detecting and debugging a violin panel, wherein a low-frequency generator and an oscillation test box are used to detect the resonance of the violin panel before installation, and the sound production effect of the violin panel is regulated based on the distribution condition of nodal lines of resonance waves. The device comprises the low-frequency generator and the oscillation test box, wherein the oscillation test box comprises a box body, a subregion detection board located above the box body, a control board located at the lateral side of the box body, and an amplifier located below the subregion detection board, a loudspeaker is arranged in the middle of the subregion detection board, and a resonance transmission rod is arranged above the subregion detection board. According to the invention, the sound production effect of the violin panel is detected accurately before installation, and the resonance of the violin panel can be regulated, so that the merit factor of violin products is improved greatly.

Description

technical field [0001] The invention relates to the manufacturing technology of musical instruments, in particular to a method and device for detecting and debugging a violin panel. Background technique [0002] The quality of a violin mainly depends on its volume and timbre. It is relatively simple to judge the volume. As for the timbre, the first thing is to have a harmonious resonance sound, which makes it beautiful, loud and mellow; the second is to have strength and penetration. Feeling, which makes it sound exciting, strong and tense. With the advantages of these two aspects at the same time, the violin has a good tone. The quality of the panel of the violin plays a key role in the sound and volume of the violin. During the production process of the violin, the violin cannot be pronounced before the panel of the violin is installed. The evaluation of its quality can only rely on the feeling of the technician. chance of mistakes, and once a panel with poor pronunciati...
