Sound generating devices and electronic equipment

Abstract

The invention discloses a sounding device and electronic equipment. The sounding device includes a magnetic circuit system, a vibration system and a metal casing. The magnetic circuit system includes a magnetic yoke, a side magnet arranged on the magnetic yoke, and The side magnetic guide plate at the upper end of the side magnet, a magnetic gap is formed inside the side magnet. The vibration system includes a diaphragm and a voice coil arranged on the diaphragm, and the voice coil at least partially extends into the magnetic gap. The metal shell is arranged in a ring shape, the diaphragm is installed on the upper end of the metal shell, the side magnetic guide plate is connected to the lower end of the metal shell, and the metal shell and the side magnetic guide plate are integrally drawn deep molding. The technical solution of the invention can increase the vibration space of the diaphragm and improve the acoustic performance of the sound generating device.

Description

technical field [0001] The invention relates to the technical field of sound energy conversion, in particular to a sound generating device and electronic equipment. Background technique [0002] At present, the casing of loudspeaker products is generally formed by integral injection molding of annular washer and plastic. In this structure, due to the limitation of injection molding conditions and in order to ensure the structural strength of the plastic casing, it is usually necessary to set the size of the plastic casing to be large, which will make the coating The tape width and wall thickness are thicker, which will reduce the vibration space of the diaphragm. When the diaphragm vibrates, the diaphragm ring is easy to touch the inner wall of the housing, resulting in poor sound output from the sound generator. Contents of the invention [0003] The main purpose of the present invention is to provide a sounding device, which aims to increase the vibration space of the di...
