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
The present invention relates to a kind of loud speaker, or rather, is a kind of electromagnetic shielding loud speaker.
Background technology
The principle difference that loud speaker is changed according to device electroacoustic is divided into multiple loud speaker, and wherein magnetic speaker uses more extensive.But, use this loud speaker can be subject to larger interference for the occasion that some electromagnetic radiation are larger.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of electromagnetic shielding loud speaker that can shield outside electromagnetic interference.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of electromagnetic shielding loud speaker, comprise a loud speaker body, described loud speaker body is provided with a magnetic part, described loud speaker body is also provided with a sounding paper, be provided with an electro-magnetic shielding cover at the middle part of described sounding paper, described electro-magnetic shielding cover is provided with an airflow hole.
As preferred embodiment of the present invention, described electro-magnetic shielding cover is made up of sheet metal.
As preferred embodiment of the present invention, described airflow hole is centrosymmetric distribution.
Because electromagnetic shielding loud speaker of the present invention is at outer setting radome of the electromagnetic induction coil of body, because it is that metal is made and can be shielded external electromagnetic signal, when speaker operation, the tonequality impact of external electromagnetic on loud speaker is less, thus substantially increases the electromagnetism interference performance of loud speaker.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of electromagnetic shielding loud speaker of the present invention;
Fig. 2 is the perspective view of the electromagnetic shielding loud speaker in Fig. 1, is now another visual angle.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides a kind of electromagnetic shielding loud speaker that can shield outside electromagnetic interference.
As shown in Figure 1 and Figure 2, a kind of electromagnetic shielding loud speaker 1, comprise a loud speaker body 2, described loud speaker body 2 is provided with a magnetic part 3, described loud speaker body 2 is also provided with a sounding paper 4, be provided with an electro-magnetic shielding cover 5 at the middle part of described sounding paper 4, described electro-magnetic shielding cover 5 is provided with an airflow hole 6.
As shown in Figure 1 and Figure 2, described electro-magnetic shielding cover 5 is made up of sheet metal.
As shown in Figure 1 and Figure 2, described airflow hole 6 is centrosymmetric distribution.
The electromagnetic shielding loud speaker of this invention is at an outer setting radome of the electromagnetic induction coil of body, because it is that metal is made and can be shielded external electromagnetic signal, when speaker operation, the tonequality impact of external electromagnetic on loud speaker is less, thus substantially increases the electromagnetism interference performance of loud speaker.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more functional module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection range that protection scope of the present invention should limit with claims is as the criterion.
