Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.
[0020] see Figure 1a and Figure 1b , Figure 1a is a structural schematic diagram of an embodiment of the horn assembly of the present invention, Figure 1b yes Figure 1a Schematic diagram of the cross-sectional structure of the speaker assembly. The horn assembly of the present embodiment comprises: a horn body 12; a magnetic shield 14, the magnetic shield 14 is arranged on one side of the sound radiation surface of the horn body 12, and several sound transmission holes 140 are arranged on the magnetic shield 14; the magnetic shield 14 14 is a ferromagnetic material, and the magnetic shield 14 is used to guide at least part of the magnetic flux on one side of the sound radiation surface of the horn body 12 not beyond the magnetic shield 14 and lead back into the internal magnetic field of the horn body 12; wherein, on the magnetic shield 14 ...

The invention discloses a loudspeaker assembly and electronic equipment. The loudspeaker assembly comprises a loudspeaker body and a magnetic shielding cover, wherein the magnetic shielding cover is arranged on a sound radiation surface side of the loudspeaker body; sound penetration holes are formed in the magnetic shielding cover; the magnetic shielding cover is made of a ferromagnetic material,and is used for ensuring that at least part of the magnetic flux on the sound radiation surface side of the loudspeaker body is limited within the magnetic shielding cover and is guided back to an internal magnetic field of the loudspeaker body; and the magnetic induction intensity of the magnetic shielding cover far from the periphery of the sound penetration holes is larger than the magnetic induction intensity of the magnetic shielding cover close to the periphery of the sound penetration holes. The loudspeaker assembly and the electronic equipment adopting the technical scheme have the advantages that the problem that iron scraps or permeable materials are absorbed and interference on other magnetically sensitive equipment is caused due to the magnetic flux on a sound radiation surface of a loudspeaker is alleviated, and the iron scraps or the permeable materials can be prevented from entering the loudspeaker assembly through the sound penetration holes.
Description
technical field [0001] The invention relates to the field of horns, in particular to a horn assembly and electronic equipment. Background technique [0002] At present, traditional speakers, small Bluetooth speakers, mobile phones, walkie-talkies, navigators, etc. on the market use electromagnetic conversion horn sounding devices (referred to as sounding mechanisms). Since the existing speakers include antimagnetic speakers, they only work on the sound radiation surface facing away Anti-magnetic treatment, due to the requirements of sound radiation, the magnetic flux leakage on the front of the sound radiation surface is not treated, resulting in magnetic leakage that will cause harm to the sound-generating mechanism itself and the surrounding magnetically sensitive devices. [0003] Take the walkie-talkie as an example. The walkie-talkie has been used for a long time in an environment with a lot of iron filings, such as a steel factory. A large amount of iron filings will b...
