Embodiment Construction

[0058] The present invention applies the plastic magnet to the design of the loudspeaker. On the one hand, the plastic magnet can be used as a support to increase the strength of the magnetic field and achieve the effect of raising the sound pressure; on the other hand, the integrated design of the speaker and the antenna of the present invention can be used to prevent magnetic flux leakage and reduce the electromagnetic interference between the antenna and the speaker.

[0059] The following description will describe the loudspeaker of the embodiment of the present invention in detail with reference to the accompanying drawings.

[0060] The invention can reinforce the problem of magnetic field leakage caused by discontinuous placement of speaker magnets at present. Place a plastic magnet around the speaker magnet section such as Figure 4 As an example, a plastic magnet bracket is mainly used for a traditional single magnetic system; the single magnetic system includes a ma...

Abstract

The invention relates to a magnetic system. The magnetic system comprises a magnet set, one or more magnetic conductive carriers and one or more plastic magnets, wherein the magnet set is provided with one or more magnets, the magnetic conductive carriers are arranged at two polar ends of all the magnets in the magnet set, and the plastic magnets are arranged on the surface not provided with the magnetic conductive carriers or the outer side of the surface. In addition, the invention provides a loudspeaker monomer and loudspeaker module applying the magnetic system. The magnetic system can further enhance the magnetic field intensity and increase the sound pressure of a loudspeaker in limited space.

Description

technical field [0001] The invention relates to a magnetic system, a loudspeaker unit and a loudspeaker module using the magnetic system. Background technique [0002] Micro speakers are commonly used in thin 3C communication products, such as smart phones, tablet computers or other mobile devices. The main principle of dynamic speakers on the market is to use the voice coil to pass current and place the voice coil in the area where the magnetic field is distributed (magnetic gap). The voice coil is thus forced to drive the diaphragm and push the air. Micro-speakers used in mobile devices are limited in size and height. In order to increase the strength of the magnetic field, a single magnetic (such as figure 1 ) is designed to increase the size of the magnet as much as possible; however, due to the limitations of the voice coil and other mechanical components, the range of increase is limited. [0003] The polarity of magnets or other magnetic substances can be divided in...
