I believe we will often hear the concept of "big voice coil speaker".
So, what is the definition of "big voice coil" speaker? Compared with ordinary horn speakers, what are the characteristics and advantages of "large voice coil speakers"?
There are many specifications of voice coils that can be applied to speakers. However, why is the "big voice coil" so attractive?
2. Heart of Horn - Working Principle Voice Coil
It can be said that voice coil is the "heart" of PA loudspeaker. Just as if the same person has a "big heart", the blood circulation will be more "surging and powerful", thus making people more "powerful"; If we also add "big heart" to the speaker, then the speaker will naturally play a better role in theory - and this is the motivation for people to design large voice coil speakers.
3. Large voice coil has great advantages
Through practical use, we can find that voice coil has the following advantages:
1. The use of large voice coil means that the speaker can use larger magnetic steel at the same time, and larger magnetic steel also means greater magnetic force, which means that the vibration of the speaker can have greater energy and better control, less distortion, richer "content" of the sound, stronger strength, and more "self-sufficiency" and "relaxation" of the sound
2. If the diameter of the cone remains the same, if the diameter of the voice coil is larger, the length of the cone from the edge to the edge of the voice coil will be shorter, and the area of the "indirect vibration part" (not the direct vibration of the voice coil, but the direct vibration part of the voice coil) in this area will also be reduced.
3. As the voice coil becomes larger, the surface area of the voice coil also increases, which also means that the heat dissipation area of the voice coil increases and the heat dissipation speed is faster, so that the voice coil can bear more power.
