At present, there are more and more audio brands on the market, and the sizes of speakers are also different, and the application scenarios are various. Although the size of the speakers are different, there is one thing that all speakers are uniform, that is, the woofer on the speaker will be larger than the mid-tweeter. Why should the size of the woofer in the audio system be so large?
sound woofer
woofer, in the sound is mainly responsible for the low frequency part of the sound, the band range is 20-200Hz, the sound produced makes the ears feel warm, and makes people excited and excited. Since the low-frequency wavelength is longer than the mid-range and high-frequency wavelength, large energy is needed to generate resonance . The larger the speaker size, the greater the energy, so the size of the woofer is larger than the size of the mid-tweeter. If the surrounding air resonance is not obvious, then the bass effect is also poor. In addition, the low-frequency sound wave of the sound has poor directivity, wide radiation surface, and energy dispersion. When propagating in the air, the unit energy at a certain distance is attenuated faster than high-frequency sound waves. Therefore, under the same transmission distance as the high-frequency sound , The woofer must increase the radiated energy of the bass; and to increase the radiated energy, it is necessary to increase the power and increase the vibration area. Therefore, the size of the woofer will be larger than the size of the mid-tweeter. This is also a way of intuitively distinguishing the woofer.
There is another obvious difference in the woofer-the magnetic steel is relatively larger. Like the woofer of the Meirui speaker factory, the Y35 Aerospace Magnet is used as the speaker magnet, which has strong power, good bass effect, and deep bass. Some customers require stronger bass, so there are dual-magnet subwoofer speakers.
