Abstract

The invention provides a loudspeaker, which includes a pot frame, a vibration system fixed on the pot frame, and a magnetic circuit system with a magnetic gap. The magnetic circuit system includes a yoke and a main magnetic circuit assembly fixed on the yoke. The vibration system includes a The diaphragm of the basin frame, the skeleton fixed on the side of the diaphragm facing the magnetic circuit system, the voice coil inserted into the magnetic gap through the skeleton, the skeleton is ring-shaped, and the diaphragm includes the middle membrane in the middle and the outer membrane surrounding the middle membrane at intervals The sound membrane, the edge of the outer sound membrane away from the media is fixed to the pelvic frame, and the skeleton connects the outer membrane and the media, and the middle membrane includes a first side connected to the skeleton and a second side connected to the main pole core; the main pole core is close to One end of the middle membrane is provided with a boss, and the boss has a second connection surface arranged towards the second side of the middle membrane, and the second side of the middle membrane is fixed on the second connection surface; since the skeleton is connected to the main pole core through the middle membrane, Therefore, the middle membrane can limit the swing of the skeleton and the voice coil, effectively solving the swing problem of the current loudspeaker vibration system.

Description

【Technical field】 [0001] The invention relates to the technical field of electronic components, in particular to a loudspeaker. 【Background technique】 [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals. It is widely used in convenient electronic devices such as mobile phones, laptop computers, and portable music players. With the rapid development of these convenient electronic devices, people's functions The performance requirements are getting higher and higher, especially for the speakers used in mobile phones, and the speakers used in these electronic devices also need corresponding development. [0003] Existing loudspeakers generally include a pot frame and a diaphragm housed in the pot frame, a voice coil and a magnetic element. The voice coil drives the diaphragm to vibrate under the drive of the magnetic element. For some speakers, the vibration amplitude of the diaphragm itself Large, the diaphragm and voice coil...

Problems solved by technology

[0003] Existing loudspeakers generally include a pot frame and a diaphragm housed in the pot frame, a voice coil and a magnetic element. The voice coil drives the diaphragm to vibrate under the drive of the magnetic element. For some speakers, the vibration amplitude of the diaphragm itself Large, the diaphragm and voice coil will swing in the normal direction of the voice coil movement direction, which will affect the stability of the vibration system composed of the diaphragm and voice coil, thereby affecting the sound quality of the speaker
