Abstract

An earphone driver includes an annular diaphragm having an inner peripheral edge and an outer peripheral edge, and an annular frame unit having an outer circular edge portion and an inner circular wall portion concentrically disposed, wherein the inner peripheral edge of the annular diaphragm is attached to the inner circular wall portion of the annular frame unit and the outer peripheral edge of the annular diaphragm is attached to the outer circular edge portion of the annular frame unit so as to close an annular space therebetween. The earphone driver further includes a magnetic means installed to surround the inner cylindrical wall portion, and a voice coil provided to a surface of the annular diaphragm facing the annular frame unit, wherein the voice coil cooperates with the magnetic means to vibrate the diaphragm when a current is passed through the voice coil.

Description

Earphone driver Technical Field Various embodiments relate generally to a headset driver. Background Conventional headphones mostly include dynamic coil speaker drivers and are classified as either closed headphones or open headphones. However, the sound quality produced by these conventional headphones suffers from drawbacks. For example, the footfall sound produced by conventional headphones is often unclear during play. In addition, the sound of a gun, the sound of a game player communication, or the sound of a person may be unclear, or low, or soft, as compared to other sounds produced by the game process. Accordingly, there is a need for an improved earphone driver capable of improving the sound quality of the earphone. Disclosure of Invention According to various embodiments, a headset driver is provided. The earphone driver includes an annular diaphragm having an inner peripheral edge and an outer peripheral edge. The earphone driver further includes a ring-shaped frame unit having an outer circular edge portion and an inner circular wall portion concentrically disposed with respect to a central axis of the ring-shaped frame unit. The inner cylindrical wall surrounds the central axis of the ring frame unit to define a hollow passage through the ring frame unit. The annular diaphragm is coaxially aligned with the annular frame unit, an inner peripheral edge of the annular diaphragm is attached to an inner cylindrical wall portion of the annular frame unit, and an outer peripheral edge of the annular diaphragm is attached to an outer circular edge portion of the annular frame unit so as to close an annular space therebetween. The earphone driver further comprises a magnetic means mounted to the ring frame unit to surround an inner cylindrical wall portion of the ring frame unit. The earphone driver further includes a voice coil disposed on a surface of the annular diaphragm facing the annular frame unit.
