The quality of the capsule determines the quality of the sound quality of the uhf ktv wireless microphone AY-URX7Ⅱ. There are two types of sound head: moving coil type and capacitive type. The moving coil type uses a coil loaded on the vibrating membrane to convert sound energy into electrical energy signals between high-density magnetic fields. There are certain limits on the voice coil characteristics of this capsule. But the basic structure is simple, the price is cheap, it is the most popular model on the market.

Condenser microphone is a microphone with high technical level in combination with electronics and structure. Its pronunciation is to use the change of inter-pole capacitance to directly convert sound into electrical energy signal with ultra-thin gold-plated diaphragm. The main feature of advanced condenser microphones is that they can show excellent original sound quality, very broad and flat high and low frequency response, very high sensitivity, large directivity and dynamic range, low distortion rate, light weight and resistance to falling, low touch noise, and are widely used. In recording studios, professional stages, test instruments and other professional equipment.
