Example Embodiment

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain that it is in a specific posture (as shown in the drawings). If the specific posture changes, the relative positional relationship, movement, etc. of the components below will also change the directional indication accordingly.

Abstract

The invention discloses a sound production device and electronic equipment, the sound production device comprises a magnetic circuit system, a vibration system and a metal shell, the magnetic circuitsystem comprises a magnetic conductive yoke, a side magnet arranged on the magnetic conductive yoke and a side magnetic conductive plate arranged at the upper end of the side magnet, and a magnetic gap is formed on the inner side of the side magnet. The vibration system comprises a vibrating diaphragm and a voice coil arranged on the vibrating diaphragm, and at least part of the voice coil extendsinto the magnetic gap. The metal shell is arranged in an annular shape, the vibrating diaphragm is installed at the upper end of the metal shell, the side concentrating flux plate is connected to thelower end of the metal shell, and the metal shell and the side concentrating flux plate are integrally formed in a deep drawing mode. According to the technical scheme, the vibration space of the diaphragm can be increased, and the acoustic performance of the sound production device is improved.

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...
