Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, if there are descriptions involving "first", "second"...

Abstract

The invention discloses a loudspeaker and electronic equipment. The loudspeaker comprises a magnetic circuit system and a vibration system, and the magnetic circuit system comprises a first magnet part and a second magnet part which are spaced to form a magnetic gap; the vibration system comprises a vibrating diaphragm and a voice coil for driving the vibrating diaphragm to vibrate, and at least part of the voice coil is located in the magnetic gap; the voice coil comprises a skeleton, a voice coil wire and a magnetic conductive sheet; the voice coil wire is wound on the skeleton so as to form at least one coil layer on the outer side wall of the skeleton in the radial direction of the skeleton; and the magnetic conductive sheet is arranged around the skeleton and is embedded in one or more coil layers. According to the invention, the probability of occurrence of undesirable phenomena such as ring rubbing caused by inclination of the voice coil is reduced, and the reliability of the loudspeaker is improved.

Description

technical field [0001] The invention relates to the technical field of acoustic technology, in particular to a loudspeaker and electronic equipment. Background technique [0002] Speakers, as common devices that can convert audio signals into sounds, are widely used in various electronic devices. At present, in the composition of the speaker, the voice coil is generally composed of a voice coil wire and a skeleton. The voice coil wire is wound on the skeleton. When the voice coil wire is energized, the magnetic field generated by the voice coil interacts with the magnetic field generated by the magnetic circuit system, making The voice coil is displaced relative to the magnetic circuit system, thereby driving the diaphragm to vibrate and produce sound. However, in the actual assembly process, due to insufficient assembly process precision and other reasons, the voice coil will be deflected and defects such as "rubbing ring" will occur during operation, which will affect the...
