Abstract

The invention discloses a loudspeaker, relates to the technical field of terminal devices and solves the problem of a poor loudspeaking effect caused by an insufficient sound pressure level in a light and thin terminal device. The loudspeaker comprises a diaphragm and a magnetic circuit system. The magnetic circuit system comprises a first magnet and a second magnet which are arranged in a sleeving manner, an interval exists between the first magnet and the second magnet, and annular magnetic steel is arranged in the interval. A first sound coil is arranged in a first interval formed between annular magnetic steel and the first magnet, a second sound coil is arranged in a second interval formed between the annular magnetic steel and the second magnet, the first sound coil and the second sound coil generate Ampere forces in the same direction to drive the diaphragm to vibrate. The loudspeaker provided by the invention is used in the technical field of terminal devices.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment, in particular to a loudspeaker. Background technique [0002] With the improvement of people's living standards, people's requirements for mobile phones, tablet computers, TVs, audio and other terminal products are not only reflected in operating performance, but also require thinner and lighter fuselages to reduce the weight of terminal equipment and improve user comfort. [0003] In the speaker of traditional terminal equipment, there is generally a set of magnetic circuit system, which includes a magnet and a voice coil. Under the action of the magnetic field formed by the magnet, the voice coil generates a driving force to drive the diaphragm to vibrate, so that the speaker has sufficient The sound pressure level ensures the normal operation of the speaker. The thickness of the magnet in the magnetic circuit system determines the size of the magnetic field generated by the...
