ULTRA-THIN TELEPHONE RECEIVER

摘要

Disclosed is an ultra-thin telephone receiver. A driving mechanism of the ultra-thin telephone receiver comprises an armature section and a coil section. The armature section is E-shaped and comprises a base portion, two wing portions, and a middle portion, the base portion, the two wing portions, and the middle portion being formed in an integrated mode. The middle portion comprises a root portion located on the base portion, and the root portion extends forward to form a vibration diaphragm portion. The coil section is arranged on the root portion at intervals in a sleeved mode. A shell of the ultra-thin telephone receiver comprises an upper shell and a lower shell. The upper shell is arranged at the top of the driving mechanism in a covered mode, and comprises a cover plate and cover edges that are formed by extending downward from the periphery of the cover plate, a first magnet is fixedly connected to an inner wall of a section of the cover plate covering the top of the vibration diaphragm portion, and the upper shell is made of magnetically soft alloy. The lower shell is arranged at the bottom of the driving mechanism in a covered mode relative to the upper shell, a second magnet is fixedly connected to an inner wall of the lower shell relative to the first magnet, and the lower shell is made of magnetically soft alloy. A sounding hole is formed in the upper shell or the lower shell. In the present invention, the thickness of an existing telephone receiver is reduced to the largest extent, and the ultra-thin telephone receiver is more suitable for the structure of a mobile phone with a narrow frame or a mobile phone which is nearly frameless.
