Problems solved by technology

The magnetic circuit system is in contact with the metal rear panel, and the heat transfer between the two is fast. When the speaker is working, the heat generated by the voice coil is diffused from the magnetic circuit system to the large-area rear panel and radiated out, which solves the problem of the speaker module. Heat dissipation problem, which also solves the problem that the power cannot be increased due to heat dissipation problem

Abstract

The invention provides a loudspeaker module which comprises an inner magnetic loudspeaker unit, a shell body and a metal back face plate, wherein the inner magnetic loudspeaker unit is connected with the shell body, the metal back face plate is connected with the plastic shell body to form a sealed cavity, the inner magnetic loudspeaker unit comprises a magnetic circuit system, and the magnetic circuit system is contacted with the metal back face plate. The loudspeaker module promotes low sound, and resolves a radiating problem of a small-field-core high-power inner magnetic loudspeaker module.

Description

technical field [0001] The invention relates to an electroacoustic device, in particular to a loudspeaker module. Background technique [0002] As the size of LCD flat-panel TVs becomes larger, the thickness becomes thinner and the frame becomes narrower, the appearance structure of the supporting speakers and modules also requires lengthening, width narrowing, and height reduction, and the requirements for electroacoustic performance indicators It is also higher; after the LCD flat-panel TV becomes larger, the required power can also be matched with the large size. Usually, the power of this type of speaker module is 3-5W, and the maximum power is 10W. [0003] Problems with previous technologies: [0004] High-temperature demagnetization caused by heat dissipation: Due to the limitation of the LCD TV structure, the design of the magnetic circuit system in the speaker module will be affected after the short axis is narrowed, especially the selection of magnetic materials, ...
