Headphone structure of interphone:

Headphones and headphones can be divided into earplug type, ear hanging type, headband type and rear hanging type.

Can also be divided into closed, open and semi-open. Closure is to wrap the user's ear through the soft sound pad brought by the worker, so that it is completely covered. This kind of earphone is relatively large because of its large sound pad, but it will not be affected when used in noisy environment.

Open earphone is a popular earphone style at present. This machine is characterized by using sponge-like microcellular foam plastic to make sound-transmitting ear pads. Small, comfortable to wear, and without a heavy pad, there will be no feeling of isolation from the outside world, but the low frequency loss is large. In terms of hearing, this earphone is still good.

Semi-open headphones combine the advantages of the above two kinds of headphones. This kind of earphone adopts multi-diaphragm structure, besides an active diaphragm, there are many passive driving diaphragms. It not only has the richness of low-frequency description, but also has many characteristics such as bright and natural high-frequency description, clear hierarchy and so on. Nowadays, this structure is widely used in many high-end headphones.
