Problems solved by technology

[0002] Traditional sound-generating devices are affected by water pressure, which will cause the diaphragm of the sound-generating device to continuously move inward. When the water pressure is too high, it is easy to cause the diaphragm to be overstretched and unable to recover effectively, causing the diaphragm to be damaged and affecting the product. Performance and waterproof effect

Abstract

The invention discloses a sound production device which comprises a vibration system and a magnetic circuit system. The vibration system comprises a vibrating diaphragm and a voice coil which are connected together. The magnetic circuit system comprises a central magnet and side magnets arranged on the outer side of the central magnet. A central magnetic conductive plate is arranged on the centralmagnet, and side magnetic conductive plates are correspondingly arranged on the side magnets, wherein the vibrating diaphragm comprises a middle part, an edge part arranged around the middle part anda reinforcing part arranged in the middle part; in the height direction of the sounding device, the side magnetic conductive plate is correspondingly located below the vibrating diaphragm, the reinforcing part is provided with an extending part extending towards the side part, and the extending part crosses the inner side edge of the side magnetic conductive plate. The technical scheme has the advantage of high water pressure resistance, and the waterproof reliability of the acoustic device is improved.

Description

technical field [0001] The invention relates to the field of sound generation, in particular to a sound generation device. Background technique [0002] Traditional sound-generating devices are affected by water pressure, which will cause the diaphragm of the sound-generating device to continuously move inward. When the water pressure is too high, it is easy to cause the diaphragm to be overstretched and unable to recover effectively, causing the diaphragm to be damaged and affecting the product. performance and waterproof effect. Contents of the invention [0003] The main purpose of the present invention is to provide a sound-generating device, aiming at improving the waterproof reliability of the sound-generating device. [0004] In order to achieve the above object, the sounding device proposed by the present invention includes: [0005] A sounding device, characterized in that it includes a vibration system and a magnetic circuit system; the vibration system include...
