Abstract

The invention provides an inner core, a loudspeaker module and electronic equipment, relates to the technical field of electronic equipment, and can give consideration to equipment thinning and audio performance at the same time. The inner core comprises a diaphragm group, a first voice coil group, a second voice coil group and a magnetic circuit system. The first voice coil group and the second voice coil group are fixed on the diaphragm group. The magnetic circuit system comprises a magnet assembly. The magnet assembly includes a first center magnet, a second center magnet, and a side magnet. The magnetizing direction of the second center magnet is the same as that of the first center magnet, the magnetizing direction of the side magnet is opposite to that of the first center magnet, an inner magnetic conductive part is arranged in a gap between the first center magnet and the second center magnet, and the first voice coil group and the second voice coil group are matched with the magnetic circuit system to synchronously drive the vibrating diaphragm group to vibrate. The kernel provided by the embodiment of the invention is used for converting an audio electric signal into sound.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202110723281.3 and the title of the invention "a core, speaker module and electronic equipment" submitted to the State Intellectual Property Office on June 29, 2021, the entire contents of which are incorporated by reference in this application. technical field [0002] The present application relates to the technical field of electronic equipment, in particular to a core, a loudspeaker module and electronic equipment. Background technique [0003] Currently, electronic devices such as personal computers (PCs), tablets, and mobile phones need to be designed to be thinner and thinner due to consumer demand. At the same time, with the improvement of consumer demand, these electronic devices are also required to achieve a better sound experience. In the electronic equipment of the prior art, in order to achieve a light and thin design, a thinner speaker module needs to be ...
