Embodiment Construction

[0035] As mentioned in the background section, the magnetic shielding structure in the prior art is not conducive to the development of thinner and lighter electronic equipment.

[0036] The reason that inventor finds that above-mentioned phenomenon occurs is, as figure 1 as shown, figure 1 It is a schematic diagram of the horn magnetic shielding structure provided in the prior art; in the prior art, in order to place the front of the horn to absorb iron filings, block the sound hole of the horn, and affect the horn, therefore, it is usually installed on the side of the sound radiation surface of the horn body 11 The magnetic shield 12 is provided with several sound-through holes 120 on the magnetic shield 12; the magnetic shield 12 is a ferromagnetic material, and the magnetic shield 12 is used for at least part of the magnetic flux on the side of the sound radiation surface of the speaker body 11 not to exceed The magnetic shield 12 is guided back into the internal magnetic...

Abstract

The invention provides a magnetic shielding structure and electronic equipment, and the magnetic shielding structure comprises a base body and soft magnet powder uniformly distributed in the base body, so the magnetic shielding effect is achieved, wherein the base body is a structure located on the sound production side of an electromagnetic conversion type loudspeaker in the electronic equipment, and the base body can be a shell, a key, a circuit board and the like of the electronic equipment located on the sound production side of the electromagnetic conversion type loudspeaker; the soft magnet powder is directly arranged in the base body, and the base body is a layer structure of the electronic equipment, so a magnetic shielding structure does not need to be additionally arranged on the back surface or the sound production side of the loudspeaker. The magnetic shielding structure provided by the invention is more beneficial to the light and thin development trend of the whole machine.

Description

technical field [0001] The invention relates to the field of electromagnetic technology, in particular to a magnetic shielding structure and electronic equipment. Background technique [0002] Traditional speakers, mobile phones with buttons, walkie-talkies, etc. use electromagnetic conversion horn generating devices (hereinafter referred to as sounding mechanisms). , The position where the horn is usually attracts a lot of iron filings, which interferes with the horn signal. [0003] For this situation, in the prior art, the magnetic shielding structure is added to the back and the sounding side of the speaker to achieve the magnetic shielding problem. However, the magnetic shielding structure in the prior art is not conducive to the development of thinner and lighter electronic equipment. Contents of the invention [0004] In view of this, the present invention provides a magnetic shielding structure and electronic equipment to solve the problem in the prior art that ad...
