Abstract

The invention discloses a loudspeaker and electronic equipment, and belongs to the technical field of acoustic equipment. The loudspeaker comprises a shell, a magnet assembly, a vibrating diaphragm, a voice coil and a first auxiliary magnet. The shell is provided with an accommodating cavity; the magnet assembly is arranged in the containing cavity and comprises a center magnet and side magnets, the side magnets are arranged on the outer side of the center magnet, and gaps are formed between the side magnets and the center magnet; the vibrating diaphragm is arranged between the magnet assembly and the shell; the voice coil is arranged on one side, close to the magnet assembly, of the vibrating diaphragm and is opposite to the gap; the first auxiliary magnet is arranged between the vibrating diaphragm and the shell; a first groove is formed in the side, facing the shell, of the vibrating diaphragm, and the first auxiliary magnet is opposite to a notch of the first groove.

Description

technical field [0001] The application belongs to the field of acoustic equipment, and specifically relates to a speaker and electronic equipment. Background technique [0002] There are speakers in the electronic equipment, which convert the electrical signals of the electronic equipment into sound signals to emit sound. The device's music, video, games, and calls all require speakers with better sound performance to improve user experience. Therefore, the requirements for the sound performance of speakers are also increasing. [0003] In the loudspeaker, a magnetic field is formed by the center magnet and the side magnets, and the voice coil is located in the magnetic field. When an alternating current is passed to the voice coil, the voice coil reciprocates in the magnetic field, thereby driving the diaphragm to move, thereby pushing the air to make sound. The magnetic field formed by the center magnet and the side magnets is stronger in the area close to the center magn...
