What material is used for the shell of the smart speaker?

What material is used for the shell of the smart speaker? Smart speaker enclosureGenerally, stainless steel, aluminum alloy and plastic are used. The stainless steel shell has the advantages of dirt resistance, strong metal texture, good sealing, better sound quality, strong plasticity, oxidation resistance, low processing difficulty, short construction period, and cost saving; However, the long mold opening time and slow processing speed of aluminum alloy lead to increased production costs; Plastics are not resistant to dirt, low texture, low strength, thermal expansion and contraction due to temperature influence, and poor sealing.

So, in comparison, it's still stainless steelSmart speaker enclosureIt would be better.

If you're talking about electrical equipment such as power amplifiers, then it's best to use copper-plated steel plates for housings. Good electromagnetic shielding performance.

Generally speaking, wood materials are better, but it also depends on your special preference for tone. The most important thing is the "sound path" design inside the speaker and the selection and design of sound-absorbing materials.

To put it simply: it is best to use pure wooden planks! The second is MDF. The most recent is ABS engineering plastics. Recently, in the domestic copycats, the audio that costs more than 1,000 is actually a paper board!

How to say it. It depends on what price you want. The general texture itself is good, its weight quality should be heavy, the heavier, the better, the sound quality effect is better and fresher, the second depends on the structure of the sound itself, which depends on your own hobbies.

Generally woody sandalwood, the highest density is the best. Thirdly, it depends on whether it is loud or not, the crisper the better.

Of course, it's pure wood, well, the general speaker seller says that his speaker is wooden, but it's actually a high-density board.

If the horn is best made of solid wood, the density is better.

Of course, the speaker is solid wood, and the sound is mainly tweeter, subwoofer, and power amplifier, and most of them now do power amplifier and subwoofer together. The sound of independent power amplifiers is generally relatively powerful. Nowadays, most of the power amplifiers are single-chip microcomputers.

The wooden material is better. And if you don't ask for good looks. Put the speaker directly into the jar, and the bass effect is quite good.

The wooden ones are better, but this is a high-end audio, and it doesn't matter if the general computer is used.

The housing of the amplifier is good with metal and shielded.

The enclosure of the speaker is made of wood. (If possible, please find a large piece of wood, open the bell mouth first after the shape is finished, and hollow out the inside from the bell mouth and the inverted hole.) One on the left and one on the left. This kind of speaker is delicious enough to be stylish. ）

You can also try the cement speaker, sonorous and powerful. ......

If you have an active speaker, it is recommended to use MDF, if you don't have it, then you like it.

Are you talking about speakers? It is best to use dense wood, such as mahogany or various mahogany.

For personal preference, I think the wooden ones are better!

The sound of the big speaker professional wood is good. mini small speaker plastic will do.

Sound quality and speaker source. The crossover also has a lot to do with it.

If you use a dense wood, the better the resonance will be.

Mahogany, not bad, but to find or need to put a mind, and then I think fine cement, the finest cement, and then the inner layer of the mud clear.

Copper and stainless steel are used for high-grade points, and aluminum alloy is used for low-level points.

The speaker cabinet is thick with oak wood!

What are the processing processes of smart speaker shells? The processing technology generally includes polishing, frosting, spraying, painting, baking, electroplating and so on. Among them, the baking paint process is the most widely used.

Its process makes the smart speaker shell have good color rendering, bright color, good finish, and strong visual impact! At the same time, the repair is strong, if the traditional paint surface is damaged, the surrounding paint surface will fall off, and there must be spot marks when repairing the paint, while the baking paint is not easy to fall off, and can be repaired without traces.

1. Welding forming: The first step is to distinguish the stainless steel calendering strip through the concave mold, U-shaped mold, and O-shaped mold, and extrude the cross-section of the steel strip into a circular process; The mold is generally composed of 4 8 groups, and the more the number of molds, the more precise and rounded the molding. When the steel strip is extruded into a circle, it is welded, and there are many kinds of welding processes, Gangzheng adopts tungsten argon arc welding, and adds mixed gas for weld protection; After the welding is completed, the stainless steel pipe blank is formed.

2. Straightening: After the pipe is formed, it is necessary to go through the straightening process to eliminate the defects such as the deformation of the diameter of the pipe and the bending of the pipe body under the action of external force, and this process is to ensure the roundness and verticality of the stainless steel pipe fittings; Gangzheng stainless steel bluetooth speaker shell inner and outer diameter error of 10mm, vertical deviation.

3. Laser cutting: laser cutting according to the size of customer needs, which is a fully automated digital cutting method, using a high power density laser beam to cut the pipe, which is characterized by very accurate size control; The completion of this step forms the preliminary pipe fittings of the Bluetooth speaker nesting.

4. Punching: The stainless steel pipe fittings are installed on the punching machine, and under the drive of power, the punching die acts on the pipe fittings for punching; The punching process has the characteristics of high precision and accurate positioning, which greatly improves the yield rate; This makes it easier for the Bluetooth speaker enclosure to be assembled at a later stage.

5. Precision polishing: After the modeling and manufacturing of Bluetooth speaker nesting is completed, it will be polished; Generally, mirror polishing, wire drawing, frosting and so on are carried out according to the needs of customers; It is completed by combining a variety of accessories such as polishing wax, slurry, hemp wheel, cloth wheel, and thousand impeller wheel.

6. Coloring treatment: the last is the coloring process, which is common in electroplating, baking paint, spraying, powder spraying and other processes; There are many color choices, among which rose gold, champagne gold, flash black, and black titanium are all very popular colors for Bluetooth speaker shells in recent years; After the coloring is completed, the coating will be strictly inspected, and wiped 30 times with a soft cloth soaked in 95% alcohol, and the substrate can not fade without fading, so as to ensure that the coating is strong enough and has a long service life.

At present, plastic is the most used, but it is not resistant to dirt and has a poor texture; There is also an aluminum alloy shell, but its metal texture is poor, the mold opening time is long, and the size is not accurate. The stainless steel material is better, the material is more tough, and the material is cost-effective; Good sound quality, high strength, good corrosion resistance, more durable than ordinary materials, the surface of the stainless steel shell can be treated with high-temperature baking paint, cost-effective, the color has been professionally matched, and there will be no color difference; This is Gangzheng stainless steel for your answer.

Special material requirements for smart speaker shells: light weight, strong plasticity in appearance, and easy processing and molding. It has excellent hardness, weather resistance, noise reduction, dimensional stability, creep resistance, low moisture absorption, heat resistance and high flame retardancy, which can provide stable support and protection for products.

Compared with plastic speakers, the advantages of wooden speakers are high density and good playback effect, cabinet material affects the performance of the speaker, the greater the material density of the speaker shell, the smaller the vibration generated by the cabinet when the sound is emitted, especially the active speaker with a high-power amplifier, so that the sound can be more realistically restored. Wood is much denser than plastic, so wooden speakers work better than plastic speakers.
