Plastics-not all toys
Plastic is one of the new speaker materials. Most plastic speakers are gorgeously dressed, even though most of them are of modest value. Their light weight and strong plasticity make them even a fashion endorsement. And the low price makes them firmly occupy the market of mini speakers, multimedia active speakers and even many outdoor audio. Also attracted the love of many young people.
However, most ordinary plastic speakers are of ordinary materials, and the box is thin and unable to overcome resonance. Therefore, the sound is generally dry, not round, and lacks smoothness. There are only a few top products (most of which are original from Europe and America). Due to the application of specially processed high-density plastics, very perfect results can be achieved. Most plastic speakers are more suitable for low-end entertainment options.
Therefore, if it is only matched with a few thousand yuan of audio-visual combination, it is enough to choose a plastic speaker; but those who have certain requirements on the sound itself, it is best not to choose such products if there is not enough budget.
Metal-Noble Storm
The metal speaker is a product with higher technical content that has only appeared in recent years. The ever-changing material characteristics allow the speaker manufacturers to integrate various industrial design concepts as they wish, which enhances the cost performance of metal speakers from an aesthetic point of view. In addition, the performance of the metal speaker in the high-frequency part is very good, and the sense of transparency is excellent.
However, like plastic speakers, this type of product also has very strong requirements for manufacturers' metal processing capabilities and design capabilities; moreover, the sound-dyeing part is more difficult to control for metal speakers. Therefore, the number of manufacturers is very limited, and the prices of intermediate products are relatively expensive. However, there are already many Japanese and Korean brands, such as Panasonic, Pioneer, etc., who have applied products of this material to suite home theaters, and have achieved good market performance.
In short, if it is not a sound combination purchased as a set, it is best not to choose metal products. Moreover, it is not easy to match the gloss of the metal with other homes.
Wood-based on primary colors
Wood is the oldest speaker material. It is also the most widely used material for making speaker cabinets. Among them, speakers made of solid wood are top grade. However, solid wood is very sensitive to humidity and can only be used when it is relatively dry.
The most wooden speakers on the market use high-density fiberboard. The overall performance of this material for sound is okay, and the processing cost is relatively low. Ordinary mid-range wooden speakers belong to this type of product.
In addition, there are speakers made of particle board, plywood, medium density particle board and other materials, which are also wooden speakers.
In short, the performance of mid-range wooden speakers for sound is generally better than similar products of plastic and metal textures, and home theaters of 10,000 yuan or more can choose to match. If it's not too much trouble, and there is this surplus money, it is also a good choice to get a solid wood speaker worth hundreds of thousands of dollars.
Phonology
Pure tone: It has two meanings: (1) refers to a sound wave whose instantaneous sound pressure changes sinusoidally with time; (2) refers to a sound with a clear single tone.
Pitch: refers to the lowest frequency component of a composite sound.
