Abstract
The invention discloses an anticorrosion loudspeaker which comprises a conical frame, T-shaped iron, a waterproof paper cone, a voice coil, a high-pitch cup and a centering support chip made of MYLAR materials. An epoxy resin layer is arranged on the outer side wall of the voice coil, epoxy resin layers are respectively arranged on the upper surface and the side wall surfaces of a column core of the T-shaped iron, the high-pitch cup is a flared barrel, openings are formed in two ends of the flared barrel, the inner end surface of the high-pitch cup is fixedly connected with the voice coil, and the outer end surface of the high-pitch cup is not higher than the upper surface of the frame. The anticorrosion loudspeaker has the advantages that the anticorrosion loudspeaker is provided with the waterproof paper cone, the centering support chip is made of the MYLAR materials which are high in barrier property, epoxy resin is arranged on exposed components, accordingly, corrosive gas can be effectively prevented from flowing into the anticorrosion loudspeaker, anticorrosion effects for internal devices can be enhanced, and the integral anticorrosion performance can be improved; the high-pitch cup is arranged in the center of the paper cone, accordingly, high-frequency output effects can be improved, and the anticorrosion loudspeaker is particularly suitable to be used during warning.
Description
Technical field
The present invention relates to loudspeaker techniques field, particularly relate to a kind of corrosion-resistant loud speaker.
Background technology
Loud speaker is a kind of very conventional electro-acoustic transducer device, existing coil-moving speaker comprises taper basin frame, be fixedly installed taper basin frame bottom T iron, be arranged on basin frame opening part and the center be fixedly connected with the vibrating diaphragm of cylindrical skeleton, on the cylindrical skeleton at described vibrating diaphragm center, be wound around by a wire voice coil loudspeaker voice coil forming, and be fixedly connected with basin frame and cylindrical skeleton respectively and can be spacing the sheet that moves both vertically up and down of described cylindrical skeleton.
Because basin frame is fixedly connected with a sheet, vibrating diaphragm, propping up the outer end of sheet and the ring of vibrating diaphragm is separately fixed on basin frame, when moving-coil speaker work, the wire of voice coil loudspeaker voice coil winding has electric current to pass through, according to left hand rule, the winding in magnetic gap can produce the power conforming to direction with the current strength of flowing through and promote vibrating diaphragm motion.Because sheet and vibrating diaphragm are movabilities on the direction of vibration of vibrating diaphragm, but have very large rigidity in the direction vertical with direction of vibration, ensure voice coil loudspeaker voice coil winding part can be in magnetic gap proper motion and deflection does not occur.
In the concrete application of loud speaker, as some security protection place, need it to there is very strong corrosion resistance, as U.S. UL1480 standard-required, endure after loud speaker is tested ten days under sulfur dioxide, carbon dioxide environment, and need it to possess high frequency alarm function, how to improve rotproofness and become the technical problem of being badly in need of solution.
Summary of the invention
The object of the invention is for the technological deficiency existing in prior art, and a kind of corrosion-resistant loud speaker is provided.
For realizing the technical scheme that object of the present invention adopts be:
A kind of corrosion-resistant loud speaker, taper basin frame, T iron, waterproof cone, voice coil loudspeaker voice coil, high pitch cup and the centring disk of being made by MYLAR material, wherein, on the lateral wall of described voice coil loudspeaker voice coil, be provided with epoxy resin layer, on the post core upper surface of described T iron and side wall surface, be provided with epoxy resin layer, the tubaeform cylindrical shell that described high pitch cup is both ends open, the inner face of described high pitch cup is fixedly connected with voice coil loudspeaker voice coil, and the outer face of described high pitch cup is not higher than basin frame upper surface.
Described epoxy resin layer thickness is at 3-5 μ m.
On the bottom surface of described T iron, offer screwed hole to be fixedly connected with circuit board.
