Full-frequency speakers are also called broadband speakers. Earlier, the speakers that can cover the frequency range of 200 to 10,000 Hertz were called full-frequency speakers, and in recent years, full-frequency speakers have been able to cover frequencies from 50 to 25,000 Hertz. The full frequency speaker sets bass, midrange and treble in one, and only one speaker can be installed on the speaker to achieve the effect of the full range.
The diaphragm used by the full frequency horn mainly has the following types:
1. Paper, because the paper has a suitable internal damping and basic enough strength, so it has been used in a large number of speaker diaphragm;
2. Plastic, polymer material itself strength is higher than paper, and by adding a variety of fillers or structural strengthening means can continue to improve the effective strength of the diaphragm, but its density is large, so the actual use of strict control of its weight and resulting in its thickness is smaller, so the overall stiffness is less than paper and other materials;
3. Metal, metal material stiffness is higher than other materials, so the design of a suitable metal diaphragm, its segmentation vibration starting frequency is much higher than ordinary materials.
