Abstract

The invention provides a loudspeaker, comprising a pot frame, a vibration system and a magnetic circuit system accommodated in the pot frame, the vibration system includes a diaphragm fixed on the pot frame, a voice coil for driving the diaphragm to vibrate and produce sound, and the magnetic circuit system includes The yoke of the pot frame, the main magnet fixed to the yoke, the secondary magnet forming a magnetic gap with the main magnet, and the upper splint stacked on the secondary magnet, the upper splint includes the body part stacked on the secondary magnet 1. The extension part bent and extended from the opposite ends of the body part toward the diaphragm and the connection part connected between the extension parts. The connection part is fixed to the basin frame. The metal insert on the side is located between the main body and the diaphragm; the diaphragm includes a vibrating part and a fixing part extending from the edge of the vibrating part, and the fixing part is fixed to the metal insert. By increasing the width of the diaphragm ring, the vibration space of the diaphragm is increased, the audio performance of the product is improved, and the product has high resistance to falling and extrusion.

Description

【Technical field】 [0001] The invention relates to the technical field of electroacoustic transducers, in particular to a loudspeaker. 【Background technique】 [0002] Speakers are widely used in portable electronic devices such as mobile phones, notebook computers, and hearing aids. With the rapid development of these convenient electronic devices, people have stronger and stronger functional requirements for them, and the loudspeaker components applied to them also develop rapidly accordingly. [0003] At present, a loudspeaker with a related structure includes a pot frame, a vibration system and a magnetic circuit system accommodated in the pot frame. Usually, the pot frame adopts an integrated structure and is made of plastic injection molding or metal materials. The pot frame made of plastic is too thin and the strength is not enough. Under the premise of ensuring enough strength, the thickness of the pot frame needs to be guaranteed within a certain range, so that the ...
