5. YAMAHA company was founded in Japan in 1887 by Torakusu Yamaha. It is an old manufacturer with a history of more than 100 years. In the early days of its establishment, the company was mainly engaged in the manufacturing of musical instrument products. To this day, musical instrument products are still the company's strength. It was more than twenty years ago that we officially entered the audio industry on a large scale. However, the company is very successful in the audio industry with its many years of experience in musical instrument manufacturing and its unique understanding of music. For example, the world's first DSP digital sound field processing system was launched by this company. Nowadays, the company has become the authority on DSP technology in the industry. Its sound card chip, wavetable synthesis and DSP technology are also well-known in the computer industry. In addition, the company is also unique in speakers, such as YST- which uses active servo technology. 1. The NS-10 speaker, which uses near-sound field technology, also has a good reputation in the audio industry. Many of the company's proprietary technologies will naturally be reflected in multimedia speakers.

6． Everyone may be unfamiliar with ALTECLANSING. If you mention "AT", a giant in the American communications industry, many people know it. In the 1930s, talkies began to become popular in the United States. At that time, AT&T's subsidiary company "Western Electric" almost monopolized the film audio equipment manufacturing industry, and ALTECServoce, a subsidiary of Western Electric, acquired a Lansing company and changed its name to ALTECLAXSING. Specializing in the design and manufacturing of speakers and speakers, the company continues to this day. ALTECLAXSING's name was once well-known in the high-end audio industry. The company became almost synonymous with high-end audio in the 1940s and 1950s. The horn-type speaker "Altec7" they produced can be described as a "famous device of a generation". Until now, many people are pursuing the "Altec7". After the 1970s, the company began to manufacture some products closer to the public. The company now It is one of the most influential manufacturers in the American multimedia speaker manufacturing industry. The earliest popular USB speakers were launched by this company.

7. The history of JBL is connected with ALTECLANSING. The founder of JBL is James Bullough Lansing. Lansing established Lansing in the 1920s (the company mentioned above that was acquired by AitecService). Lansing Company). Lansing led the Lansing Company, which was mainly engaged in the manufacture of speaker units in the 1930s. After the Lansing company was acquired by Bullough Lansing in 1941, it was still engaged in speaker manufacturing. In 1946 Lansing left ALTECLANSING and established JBL. JBL is mainly engaged in the manufacturing of professional speakers and high-end (audiophile-grade) speakers, and has a high status in the audio industry. The company's multimedia speaker design is very unique, for example, in order to prevent the active part of the amplifier from occupying the limited space of the speaker and thus affecting the sound quality. Therefore, the amplifier part and the speaker part in the company's multimedia speakers are basically separate.

8. BOSE was founded in 1964. BOSE is located in Femincheng, Massachusetts, the United States, together with the famous MIT. The company was founded by Dr. Amar G. Bose, a professor in the Department of Electrical Engineering at MIT. Since its establishment, the company has been engaged in research, development and manufacturing of speakers, loudspeakers and electroacoustic theory. The company has made great achievements in the manufacturing of speaker units and the practical application of electroacoustic theory. Especially in the research and manufacturing of high-power, small-size, full-band speakers, it is the first of its kind in the industry and has created a brand-new concept. The company's main products are professional audio, home audio and multimedia speaker products. Because the company uses its high-quality speakers for multimedia speakers, the company's multimedia speakers are known for their compact size and excellent sound quality.

9． POLKAUDIO Company is a well-known audio product manufacturing company in the United States. It has a history of producing audio products for more than 20 years since its establishment. The company's products are very famous in the home high-end audio and car audio industries, and also have a certain influence in professional audio. The company is also one of the brands with a high market share of multimedia speakers in the US market.

10. SoundWorks is a small-scale electrical appliance manufacturing company located in Cambridge, Massachusetts, with a history of only ten years. However, since it was acquired by Singapore Innovation Company two years ago, the company's products have only become known to computer users. The company's main products are multimedia speakers and NV audio products, and it has an OEV factory in mainland China. (CambridgeSoundWords' products are of better quality, and the price is relatively easy to accept. General-purpose multimedia speakers are mainly used in general multimedia computer systems, and their prices have certain requirements. About 100 yuan is the ideal price. At this price , there are many plastic boxes to choose from on the market, and there are also some wooden boxes, so the range of choices is quite large.

However, for a product at this price point, you should not have too high expectations for its sound quality. As long as its quality is reliable, its after-sales service is good, and its electroacoustic performance requires a high signal-to-noise ratio.

Here I have the following suggestions: First, try to use the domestic brands mentioned above; second, choose models that are commonly used by everyone (such as large quantities, low prices, and stable performance) such as Edifier , HiVi, Arlanshi, Maibo and other brands; third, look at the signal-to-noise ratio (S/N) on the manual. The S/N requirement of this level is >70dB. Be sure to turn on the power and listen. When there is no music signal, turn the volume to the maximum (if it has a treble and bass boost function, increase the treble and bass boost to the maximum at the same time). Put your ear against the speaker mouth and there should be no obvious noise. If The noise is not too loud, so play some music and listen to it. When the volume knob is placed in the middle position, the music you hear should have no obvious distortion (it will sound unnatural). In addition, the appearance and craftsmanship of the speaker should be durable, and the weight of the cabinet should not be too light. There should be no noise inside when shaking. Instructions, warranty cards and accessories must be complete. Finally, check the antimagnetic performance of the speaker. Low-end and brand-name multimedia speakers often do very poorly in this regard. Brand speakers generally do not have too many problems in this regard. In addition to meeting general usage requirements, multimedia speakers for gaming and AV purposes (home theater) must also have characteristics suitable for gaming and home theater. The characteristics of multimedia speakers used for games and home theaters are: first, they require a wide frequency response, especially the bass, which needs to dive deeper and have weight; second, they require a certain dynamic range, which has a certain impact on the electroacoustic power. The requirements should generally be greater than 15W; the third is to have a sound field simulation playback function so that you can feel "in a game or movie environment."

I would also like to point out here that when playing games on a computer, the role of the sound card is also very important. Only with a good sound card can multimedia speakers play their role. Therefore, for gaming purposes, I strongly recommend using a sound card with EAX or A3D function, and preferably also supports four-channel mode. Of course, you can play games and use it for home theater with ordinary speakers, but you won’t experience the desired effect. After choosing a good sound card and multimedia speakers, you will definitely feel how wonderful the game world and home theater are.

For multimedia speakers for gaming purposes and home theater, I recommend the innovative Pcorks4.1 (recommended for gaming), DTT5.1 (home theater) and JS’s J-9902 (with AC-3) for entry-level use. ; To upgrade, I recommend the innovative FPS2000D; of course, advanced users have to choose and match by themselves. The principle of selection is an amplifier with DolbyAC-3 (DolbyDigital) and a 5.1-channel speaker. Using a multimedia computer for music appreciation is a wonderful experience and enjoyment. While working on the computer, use the computer multimedia speakers to play beautiful music. When you are concentrating, turn down the volume of the music as background music. When taking a break, turn up the volume of the music to express your emotions. Therefore, using a multimedia computer to enjoy music is not only a way to improve efficiency, but also a kind of beautiful enjoyment. It really kills two birds with one stone.

Using a multimedia computer to enjoy music naturally has certain requirements for multimedia speakers. It requires speakers with good sound quality, a certain degree of fidelity, and a certain degree of artistic appeal. Of course, the signal-to-noise ratio requirements are also relatively high, generally greater than 80dB, preferably greater than 85dB. The principle is that in the dead of night, no noise can be heard from the speakers. In addition, you must choose a sound card with better quality. Here I recommend the innovative SBLivelValue. The simpler the function of the speaker for listening to music, the better. Do not have any SRS function, and it is best not to have a treble and bass boost function. Among the domestically produced boxes, you can choose brand wooden boxes priced around 600 yuan or some of the better-quality 2.1-style speakers introduced above. If you are a DIY enthusiast, you may wish to transform your original multimedia speakers yourself (how to transform will be introduced in a separate article in the main issue of Microcomputer magazine in the future).

Among imported products, you can choose a 2.1-type plastic box. If the requirements are higher, you can choose an independent speaker-specific amplifier (domestic Hi-F1 transistor amplifier that costs about 1,000 yuan. For example, "Jidian" brand PA-60, PA-80s ) and audio speakers (such as domestic "Boliang", "Masterpiece", "Huiwei", etc.)

I personally believe that to maximize the performance of the sound card, the investment budget for multimedia speakers should be:

●Ordinary users: 1-2 times the price of the sound card

●Game and AV users: 1-5 times the price of the sound card

●Audio users: 2 times the price of the sound card -10 times

Buying speakers with this budget will be worthy of the sound card you choose. At present, most computer enthusiasts in China only pay attention to sound cards and despise speakers. This is completely wrong. In addition, when listening to music with multimedia speakers, the placement of the speakers has a greater impact on the sound playback effect. We will talk about this issue specifically in the following article. The most important thing for audiophiles is their personality. They believe that only their own choice is the best. Everything in it is infiltrated into their personality and culture (in fact, our DIY is the most important thing about personality and culture). He will consider many aspects such as technology, art, psychology and culture.

Some principles to consider:

●First, there must be a systematic concept. That is, for a system to have good effects, every part of the system must be balanced, that is, no link can become a bottleneck. For example, starting from CD-ROM, to the selection of sound card, and then from amplifier to speakers, as well as the selection of connection methods and connection materials of the above parts, all must be carefully selected and considered.

●Second, we must consider the characteristics of the computer system, such as digital interference problems, digital sound problems, near sound problems, antimagnetic problems, etc.

●Third, you must consider the main purpose and use of the system you build. In fact, no system is the best in all aspects.

●Fourth, in such a system, you cannot find a multimedia speaker that is completely suitable for you on the market. In fact, you need to choose your ideal match in the high-end audio market. . However, there is a view in the audiophile circle that it is impossible to enjoy high-fidelity music with a computer, let alone HI-End.
