Abstract:
Provided is a micro speaker, comprising: a basket; and a vibration system and a magnetic circuit system respectively received in the basket. The magnetic circuit system is used to drive the vibration system to vibrate and generate sound. The magnetic circuit system has a magnetic gap. The vibration system comprises a first diaphragm fixed to the basket and a voice coil inserted into the magnetic gap and used to drive the first diaphragm to vibrate. The basket comprises multiple side walls arranged at intervals and a fixing portion connecting two adjacent side walls. The thickness of the fixing portion is greater than the thickness of the side wall. The fixing portion of the basket in the micro speaker has increased thickness, thereby increasing fixing areas thereof at which other elements can be fixed.
