Background

The microphone, known as a microphone, is translated from an english microphone (microphone), and is also called a microphone or a microphone. A microphone is an energy conversion device that converts a sound signal into an electrical signal. There are classes of moving coil, capacitor, electret and recently emerging silicon micro-microphones, but also liquid microphones and laser microphones. Most microphones are electret condenser microphones which operate on the principle of using a diaphragm of polymeric material with permanent charge isolation, and are widely used in headphone products.

Most of microphones adopted by existing earphones in the market at present do not have a telescopic function, and the microphones are placed in the air when not used, so that unnecessary loss can be caused if the microphones are damaged carelessly. The microphone is not flexible, so that the microphone cannot be over against the mouth during speaking, and the sound production effect is poor. To this end, we propose a headset that is retractable.
