How should the speaker panel solid wood be treated to achieve the best results?

If you want to achieve a better effect of speaker board (solid wood), you can follow the following method:

1. The volume of the speaker must be done in accordance with the size requirements of the speaker, and the volume is selected as a plate, and the dense and uniform material is selected, which is hard.

2. Add alkali, formaldehyde, etc. for cooking.

3. Fully dried, shaded, not dried.

4. There are many kinds of wood with tung oil, and the quality is very different.

5. If there is too little paint, there will be no good bass effect.

The material of the speaker is generally divided into three categories:

1. Logs.

Logs refer to the boards that are untreated and are virgin wood. Due to the non-uniform density, we can judge by striking different parts of the plate according to its different sounds. When using such a cabinet, the sound quality of each speaker will be different, and the quality will not be well controlled.

Except in the initial processing of the logs, very precise corrections can be obtained. But it also increases its cost. At present, the common practice is to use the wood grain of the log as a decoration.

2. Synthesis.

This type of material requires the wood to be chemically treated to make the wood products waterproof and mothproof, and then pressed. The synthetic sheet material is uniform, and the quality of the speaker can be well controlled. So most of the speakers we see so far are made of synthetic sheets.

3. Plastics.

The main feature of plastic speakers is that they are easy to process, and the shape can be designed to be more beautiful, getting rid of the rigid brick-shaped appearance of wooden speakers.

1. The volume of the speaker must be done in accordance with the size requirements of the speaker, and the volume is selected as a plate, and the dense and uniform material is selected, which is hard.

2. Add alkali, formaldehyde, etc. for cooking.

3. Fully dried, shaded, not dried.

4. There are many kinds of wood with tung oil, and the quality is very different.

5. If there is too little paint, there will be no good bass effect.

The plate used to make the speaker should have a good fiber density, so that it has a strong ability to suppress vibration. At the same time, the plate should have the characteristics of moisture-proof and not easy to deform. At present, the widely used boards are mainly medium fiberboard and particleboard; This is followed by log boards, such as ash, riverwood, rosewood, birch, walnut, maple and sour branches.

High-grade speakers can be made of sandalwood. Choose hard, fine-grained wood, which is also an excellent wood for speakers.

High-grade logs generally have high fiber density, high hardness and low shrinkage. Its wood needs to be evaporated, dried or naturally dried and aged for more than 1 2 years before it can be used to make speakers. Only in this way can the speaker not be easy to deform and crack.

The use of high-grade wood to make speakers is costly, and the use of narrow-sided log boards requires splicing, which will increase the difficulty of production, so it is rare to use log boards.

Splint is a kind of large-area flat plate of mechanism plate. Its board surface is large, easy to cut, easy to process, suitable for large and small speakers. However, because the board is laminated into a plate with adhesive, it is easy to be damp and degummed, deformed, and even eaten by insects.

Particleboard is a board made of wood chips that are processed into particles of varying thicknesses, glued with adhesives, and mechanically hot-pressed. There are two types of particleboard: single-layer and multi-layer. The wood chips inside the single-layer board are evenly distributed, with high hardness and smooth surface; The inside of the multi-layer board is arranged in layers according to the size of the wood pellets, with small surface particles and high density, and large intermediate particles and small density (or made by layering and crossing according to the size of the density).

Due to the large particles, the pressed board is looser, has low strength, is afraid of moisture, and is easy to break. Its cross-section is rough and difficult to process flat, so it is only suitable for making undemanding loudspeakers and small loudspeakers.

MDF is a new high-tech product that has risen in recent years. It is made of roots, branches, stems, etc. in trees, processed into fine fibers, and then mechanically heated into various specifications of density sheets (MDF) with filler binders. The internal material structure of fiberboard is uniform and fine, with good toughness, moderate strength, moisture resistance, not easy to deform, smooth surface and strong damping characteristics.
