Abstract

The invention discloses an electromagnetic shielding loudspeaker. The electromagnetic shielding loudspeaker comprises a loudspeaker body; a magnetic part is arranged on the loudspeaker body; sound production paper is further arranged on the loudspeaker body; an electromagnetic shielding case is arranged in the middle of the sound production paper; airflow holes are formed in the electromagnetic shielding case; the electromagnetic shielding case is manufactured by use of a metal sheet; the airflow holes are symmetrically distributed about a center. The shielding case is arranged outside the electromagnetic induction coil of the body of the electromagnetic shielding loudspeaker, and as the shielding case is manufactured by use of a metal to shield external electromagnetic signals, the influence of the external electromagnetic field on the tone quality of the loudspeaker is low in work, and therefore, the electromagnetic interference resistance of the loudspeaker is greatly improved.

Description

technical field [0001] The invention relates to a loudspeaker, more precisely, an electromagnetic shielding loudspeaker. Background technique [0002] Loudspeakers are divided into many kinds of loudspeakers according to the principle of electro-acoustic conversion, among which electromagnetic loudspeakers are widely used. However, for some occasions where the electromagnetic radiation is large, the use of this kind of speaker will be subject to relatively large interference. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing an electromagnetic shielding loudspeaker capable of shielding external electromagnetic interference. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] An electromagnetic shielding loudspeaker, comprising a loudspeaker body, a magnetic component is arranged on the loudspeaker body, a sounding paper...
