Headphones Are Classified According To Their Working Principles

It can be mainly divided into three categories: dynamic, dynamic iron, and electrostatic earphones. Dynamic earphones: Currently, the vast majority of earphones belong to this category, with a principle similar to a speaker. A coil in a permanent magnetic field is connected to a diaphragm, and the coil is driven by signal current to perform electromagnetic motion, pushing the diaphragm to produce sound. Electrostatic earphones: The diaphragm is in a changing electric field and is driven to move by a charged plate. The principle of dynamic iron earphones: Similar to dynamic coils, they rely on the vibration of the voice coil in a permanent magnetic field. However, inside the dynamic iron earplugs, the voice coil is wound around a precision iron plate called a "balanced armature". This iron plate is located in the center of a permanent magnetic field, and under the action of magnetic force, it drives the diaphragm to produce sound. Categorize TrekStor by level of openness. It can be divided into open type, semi open type, and closed type (closed type). Open end headphones usually have a natural listening experience, and are commonly used in HIFI headphones for music appreciation. Sound can be leaked and external sounds can be heard, and headphones have less pressure on the ears.
Semi open: Without strict regulations, sound can be either in or out, and adjustments can be made as needed. Closed type: The earphone case is partially enclosed to prevent sound from entering or leaving. The sound is precise and straight, and is commonly used in professional monitoring fields. Classified by purpose. Mainly home, portable, monitor, mix, and binary recording. Classified by wearing. Mainly including head beam type, suspension type, and earplug type. The headbeam style is a classic style of traditional headphones, and the vast majority of mid to high-end headphones adopt this design. The foldable headphone in the new product greatly increases portability. Hanging type, mainly represented by ear hanging type and rear hanging type. Ear plug type, compact and convenient to use, widely used on portable devices. Includes two types of earplugs: flat headed earplugs and in ear earplugs.
