Multimedia speakers features-Alice factory

October 22, 2021

1. Active speakers

The so-called active speakers, in simple terms, seem to be understood as speakers that require power input. But in fact, the strict definition of active speakers refers to speakers that contain power amplifier circuits in the audio system. Some special speakers do not have a power amplifier circuit, but still need power input, such speakers can not be called active speakers.

2. Antimagnetic speaker

Because multimedia speakers need to be placed next to the computer monitor, they have special antimagnetic requirements. The speakers must use antimagnetic speakers (the so-called magnetic enclosed speakers or "permanent magnet" speakers), and the power amplifier circuit cannot use electromagnetic waves to leak out. Larger design.

3. Near sound field

Compared with the above two concepts, this concept is more complicated to understand. The so-called near-field speaker means that it is very close to the listener during playback, generally less than one meter. And semi-free, it means that it has more relaxed requirements on the position and posture of the listener. For speakers such as HI-FI, you may have heard of a term "emperor position". The audience can only hear the best sound when they are in this position. However, for multimedia speakers, it is obvious that users cannot be required to sit still in the "emperor's seat" like enjoying HI-FI. For "semi-free near-field" speakers, it is necessary to make a special design for its acoustic structure, which is completely different from ordinary HI-FI or home theater speakers, so multimedia speakers are by no means a reduction of HI-FI speakers (while domestic Many manufacturers have made serious mistakes on this issue).

4. Low power

Due to the limitation of the power supply equipment of the computer system, the multimedia speaker itself is a near sound field system, so the multimedia speaker is a low-power system, generally only a few tens of watts, such as HI-FI or home theater, the situation is hundreds of watts. If it does not exist, it requires the design of its power amplifier circuit to have a good sound quality performance at the smallest possible power, which is also different from home audio.

5. Positioning requirements

Anyone with a little knowledge of speakers should know that the placement design of speakers has a huge impact on sound quality. But for multimedia speaker design, this must be relaxed. Because it is impossible for a computer desk to provide a good placement environment, let alone a large placement space, the stability of a computer desk is never comparable to that of a dedicated speaker stand. Therefore, in the design of multimedia speakers, it must be designed into a structure that requires very loose positioning (this is also one of the current blind spots in the design of domestic manufacturers).

6. Sound correction

The ideal sound box should minimize the "sound stain" of the sound, that is, the influence of its own characteristics on the source sound, but multimedia speakers cannot require this because the sound source of the multimedia speaker, that is, the sound quality of the sound card or CDROM drive is not high , In this way, the multimedia speakers must have a certain sound correction effect to ensure that the final sound effect that the user hears is the best. A typical example here is the innovative speaker design. Over the years, many users have felt that the effect of innovative speakers when paired with innovative sound cards is significantly better than that of other brands of sound cards or speakers combined with innovative products. The main reason is that the innovative sound card is designed to deal with the defects of the innovative sound card's poor treble and extreme bass, and the strong digital sense, which makes up for the source sound defects of the innovative sound card.

7. High cost performance

The speaker is reasonably priced, and you can hear high-quality music or sound at a low price.
