Abstract

The invention relates to the technical field of electro-acoustic transduction, and provides a loudspeaker, a basin frame with a storage space, a vibration system and a magnetic circuit system accommodated in the storage space, the vibration system includes an upper sound film fixed on the basin frame, a set The voice coil on the side of the upper sound film close to the magnetic circuit system, and the centering strut fixed on the side of the voice coil away from the upper sound film, the end of the centering strut away from the voice coil is fixed on the basin frame, and the vibration system also includes support The supporting piece includes a main body that is attached to the voice coil, and a bending portion that bends and extends away from the side of the main body away from the upper sound diaphragm and away from the voice coil. One side is attached and fixed to the fixing part, and the bending part is at least partially attached to and fixed on the fixing part. The technical proposal solves the swinging problem of the loudspeaker vibration system in the prior art, so as to improve the acoustic performance of the loudspeaker.

Description

【Technical field】 [0001] The invention relates to the technical field of electro-acoustic transduction, 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 mobile phones, notebook computers, MP3 / MP4 and other convenient electronic devices. With the rapid development of these convenient electronic devices, people's functional The requirements are getting higher and higher, especially for speakers used in mobile phones, and the speakers used in these electronic devices also need corresponding development. [0003] The loudspeaker in the current related art includes a basin frame, a vibration system housed in the basin frame, and a magnetic circuit system. The vibration system generally includes a diaphragm and a voice coil that drives the diaphragm to vibrate. The problem of swinging, such as the voice coil is prone to swinging during the vibration p...
