The Effect of Box Material on the Quality of Soundbox

At present, the materials used for speakers are mainly plastic box and wooden box. Material thickness and quality are directly related to the cost of speakers, and also affect the performance of speakers. The greater the material density of the speaker shell, the smaller the vibration generated by the speaker when it makes sound, especially the active speaker with high power amplifier. The thickness of the plate is a strong guarantee for the realization of the ultra-bass effect to a certain extent. Therefore, the bass effect of the plastic speaker is not complimentary. Obviously, low-end audio products must be plastic. But is the medium-range speaker definitely made of wood? The answer is No. This class of speakers is made of both wood and plastic shells, but some of the imitations have completely reached the level of falsehood. Medium and high-grade products are definitely made of wood, but the use of medium-density board, or multi-layer board, also has different effects on sound quality. Even with the same board and the same output power, different design structures and different box sizes, the sound quality may vary greatly. However, although some speakers use plastic boxes, but also outstanding, such as CREATIVE Soundworks speakers, not only use plastic shell, but also the volume is not large, the first impression is nothing special, but after listening and comparing, I feel really extraordinary, whether it is timbre or timbre has reached professional level, bass also has a strong shock. Power, of course, is not cheap.
What should I pay attention to when choosing speakers?
First, we should pay attention to whether the timbre output of the speaker is uniform. Because the sound source of multimedia music is mainly game and general music, the proportion of tenor is larger, and the proportion of bass is smaller.
Secondly, attention should be paid to the localization ability of sound field. The positioning ability of speakers is directly related to the effect of playing games and watching DVD movies.
Thirdly, we should pay attention to the dynamic amplification limit of the speaker frequency domain, that is, whether the speaker can maintain uniform and clear source signal amplification ability in the whole sound domain when the user turns the speaker volume on and exceeds a certain limit.
Fourth, special attention should be paid to the resonance of the speaker box. Generally speaking, when the speaker with thin box or plastic shell is output at low frequency and large volume below 200 Hz, resonance will occur. Cabinet resonance will seriously affect the quality of the output sound, so users should try to choose wooden enclosure speakers when choosing speakers.
Fifth, we should pay attention to whether the chassis is anti-magnetic. Because the display is very sensitive to the surrounding magnetic field, if the magnetic field of the speaker is larger than that, it will affect the image on the screen, and even lead to a decline in the lifetime of the display, so special attention should be paid to the selection.
Sixth, we should pay attention to the tightness of the speaker box. Because the better the closeness of the speaker, the better the quality of the output sound. The airproof check method is very simple. Users can put their hands outside the inverted hole of the speaker. If there is obvious phenomenon of air rushing out or sucking in, the airproof performance of the speaker is good.
Having said so much, the topic about the speaker is far from finished. It is limited to the length of the article, so I want to talk with you about important topics. There have always been different opinions about voice. We just hope to convey to you the idea that voice is an important part of computer. We must not despise it.
