ADDASOUND TELLS YOU HOW TELEPHONE HEADSET WORKS
Currently, most telephone headsets have the working principle of moving coil type electro-acoustic conversion. As the earliest electro-acoustic conversion method used on headsets, the moving coil type is similar to the conventional speaker system. The diaphragm is structurally connected to a cylindrical coil in a permanent magnetic field, and the coil drives the diaphragm to sound under the signal current. The working efficiency of the moving coil headset is higher than others. Theoretically, the larger the size of the drive unit, the better the performance. 1. The principle of moving coil telephone headset There are differences in the diaphragm structure between a moving coil corded phone headset and a common soundbox. The edges of the diaphragm of the soundbox are generally fixed on the elastic medium, which is mostly conical in shape. And the vibration power is provided by elastic media. For moving coil corded phone headset, the diaphragm edges are d...
