A headphone is an audio device used to place it on the ear for listening to music or answering calls. Typically, headphones consist of the following main components:
1. Driver unit: The driver unit of the earphone consists of two parts, namely a magnet and a coil. When current passes through the coil, it interacts with the magnet, causing the drive unit to produce sound.
2. Shell: Battery shells are usually made of plastic or metal materials, one of which is to make headphones more sturdy. It also has good sound insulation effect, which can reduce the impact of external noise.
3. Adjuster: An audio regulator is a device used to control volume and sound quality. Through it, audio can be adjusted to make the volume and sound changes more natural, while ensuring the quality of the sound remains unchanged.
4. Lead: The lead of the earphone connects the driver unit and audio device. The lead wire is made of copper wire to provide connectivity and can be adjusted in length.
5. Plug: A plug is a metal connector used to connect headphones and audio devices. Its main purpose is to ensure smooth current transmission and better audio performance.
Overall, all parts of the headphones are designed to provide a better audio experience. Each part plays an important role, and good coordination can enable headphones to leverage their advantages. At present, headphones not only have good sound quality, but more importantly, they incorporate biometric sensing technology to ensure longer wearing time without discomfort.
