Loudspeaker and electronic equipment

Abstract

The invention discloses a loudspeaker and electronic equipment, and the loudspeaker comprises a magnetic circuit system which comprises a first magnet part and a second magnet part which are arranged at an interval to form a magnetic gap, a first magnetic gap is formed between two opposite opposite magnetic poles at the upper parts of the first magnet part and the second magnet part, a second magnetic gap is formed between two opposite opposite magnetic poles at the lower parts of the first magnet part and the second magnet part, and the magnetic pole distribution directions of the two opposite opposite magnetic poles at the upper parts and the two opposite opposite magnetic poles at the lower parts are opposite. The loudspeaker also comprises a vibration system, and the vibration system comprises a vibration diaphragm and a flat voice coil; the flat voice coil is located in the magnetic gap, the axial direction of the flat voice coil is perpendicular to the vibration direction of the vibration diaphragm, the flat voice coil is provided with two first wire sections distributed in the vibration direction at intervals, and the two first wire sections are located in the first magnetic gap and the second magnetic gap respectively; and the vibration diaphragm is in a bent shape and protrudes towards the direction far away from the flat voice coil. The loudspeaker also comprises a first bracket which is connected with the vibrating diaphragm and the flat voice coil; and a second bracket, wherein the second bracket and the first bracket are arranged at an interval and are respectively connected with the vibration diaphragm and the flat voice coil.

Description

technical field [0001] The invention relates to the technical field of sound energy conversion, in particular to a loudspeaker and electronic equipment. Background technique [0002] Due to the consideration of portability, comfort, and aesthetics, electronic devices, such as mobile phones or wearable smart terminals, have relatively strict size requirements, and the size and thickness tend to be miniaturized. Therefore, after removing various main components such as chips, batteries, motherboards, and motors, the space left for the built-in speaker is very small, that is, the size of the speaker is generally smaller, and its thickness is getting thinner and thinner. [0003] However, the performance of the speaker is usually positively correlated with its size. The large size means that the magnetic circuit system and the diaphragm of the speaker can be larger, and the vibration effect of the diaphragm is better. However, it is difficult for traditional loudspeakers to coo...
