Loudspeaker and electronic equipment

Abstract

The invention discloses a loudspeaker and electronic equipment. The loudspeaker comprises a vibration system and a magnetic circuit system; the magnetic circuit system comprises a first magnetic group, a second magnetic group and a third magnetic group which are sequentially arranged in the vibration direction of the vibration system, and the first magnetic group comprises two first magnets which have opposite magnetic poles and are arranged at intervals; the second magnetic group comprises two second magnets which are arranged at an interval, two magnetic poles of the second magnets are distributed along the vibration direction, and the distribution directions of the magnetic poles of the two second magnets are opposite; the third magnetic group comprises two third magnets with opposite magnetic poles and arranged at an interval; the first magnet, the second magnet and the third magnet which are located on the same side form a Halbach array, and the opposite sides of the two Halbach arrays are magnetic field enhancement sides; a first magnetic gap and a second magnetic gap are respectively formed by a gap between the two first magnets and a gap between the two third magnets; the vibration system comprises a vibration diaphragm and a flat voice coil, and the axial direction of the flat voice coil is perpendicular to the vibration direction.

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] For dynamic speakers, their acoustic performance is directly related to their size. The larger the size, the better the acoustic effect, and the smaller the size, the worse the acoustic effect. [0003] 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 speakers is very small, and it is difficult to improve the performance of the speakers. [0004] For example, for an electronic device with a circular shell, since conventional speakers have a straight-edge structure, when they are inst...

Problems solved by technology

Therefore, after removing various main components such as chips, batteries, motherboards, and motors, there is very little space left for the built-in speakers, and it is difficult to improve the performance of the speakers.

[0004] For example, for an electronic device with a circular shell, since conventional speakers have a straight-edge structure, when they are installed into a circular dial, they cannot be well covered and compatible, and the space is wasted, which is not conducive to improving the performance of the speaker.
