Description
Technical field
The utility model relates to loudspeaker techniques field, particularly relates 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 frame, be fixedly installed T iron bottom taper frame, be arranged on frame opening part and the center is fixedly connected with the vibrating diaphragm of cylindrical framework, the cylindrical framework at described vibrating diaphragm center is wound around by a wire voice coil loudspeaker voice coil formed, and is fixedly connected with frame and cylindrical framework respectively and can the sheet that moves both vertically up and down of spacing described cylindrical framework.
Because frame is fixedly connected with a sheet, vibrating diaphragm, the outer end of sheet and the ring of vibrating diaphragm are separately fixed in frame, during 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 and move with flowing through power that current strength conforms to direction and promote vibrating diaphragm.Because sheet and vibrating diaphragm are movabilities on the direction of vibration of vibrating diaphragm, but then have very large rigidity on the direction vertical with direction of vibration, ensure voice coil loudspeaker voice coil windings section can in magnetic gap proper motion and deflection does not occur.
In the embody rule of loud speaker, as some security protection place, it is needed to have very strong corrosion resistance, as U.S. UL1480 standard-required, loud speaker tests endure after 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 being badly in need of solving.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of corrosion-resistant loud speaker.
The technical scheme adopted for realizing the purpose of this utility model is:
A kind of corrosion-resistant loud speaker, taper frame, T iron, waterproof cone, voice coil loudspeaker voice coil, high pitch cup and the centring disk be made up of MYLAR material, wherein, the lateral wall of described voice coil loudspeaker voice coil is provided with epoxy resin layer, the post core upper surface of described T iron and side wall surface are provided with epoxy resin layer, described high pitch cup is the tubaeform cylindrical shell of both ends open, and 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 frame upper surface.
Described epoxy resin layer thickness is at 3-5 μm.
The bottom surface of described T iron offers screwed hole to be fixedly connected with circuit board.
The outer peripheral edges of described frame offer equally distributed installing hole, described outer peripheral edges upper surface is provided with sealing gasket, described sealing gasket is become multistage by even partition, and hop count is identical with installing hole number, and Qie Meiduan center is provided with the breach corresponding with described installing hole.
Every section of described sealing gasket end is provided with corresponding ladder platform.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts waterproof cone, and utilize the MYLAR material of high obstructing performance to prepare centring disk, epoxide-resin glue is set in exposed component simultaneously, can corrosive gas be effectively avoided to enter, strengthen the anti-corrosion effects of internal components simultaneously, improve overall corrosion resistance, high pitch cup is set at cone center simultaneously, improve high frequency output effect, use when being especially applicable to report to the police.
Accompanying drawing explanation
Figure 1 shows that the structural representation of corrosion-resistant loud speaker of the present utility model;
Figure 2 shows that the cross section structure schematic diagram of corrosion-resistant loud speaker of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As illustrated in fig. 1 and 2, corrosion-resistant loud speaker of the present utility model comprises taper frame 1, T iron 2, waterproof cone 3, voice coil loudspeaker voice coil 4, high pitch cup 5 and the centring disk 6 be made up of MYLAR material, wherein, the outer side surface of described voice coil loudspeaker voice coil is provided with 3-5 μm of epoxy resin layer, on the post core upper surface of described T iron and side wall surface, distribution is provided with 3-5 μm of epoxy resin layer, described high pitch cup is the tubaeform cylindrical shell of both ends open, the inner face of described high pitch cup is fixedly connected with waterproof cone with voice coil loudspeaker voice coil simultaneously, be preferably bonding connection, the height of high pitch cup is as far as possible higher, barrel adopts curve shape as far as possible, but pure tone can not be caused bad or beat the problems such as face shield higher than cone.
The utility model adopts waterproof cone, and utilize the MYLAR material of high obstructing performance to prepare centring disk, epoxide-resin glue is set in exposed component simultaneously, can corrosive gas be effectively avoided to enter, strengthen the anti-corrosion effects of internal components simultaneously, improve overall corrosion resistance, high pitch cup is set at cone center simultaneously, improve high frequency output effect, use when being especially applicable to report to the police.
Further, for improving installation capability, the bottom surface of described T iron offers screwed hole so that circuit board is fixedly connected with.
Preferably, for promoting overall sealing, prevent corrosive gas from entering, the outer peripheral edges of described frame offer equally distributed three installing holes, the back-up ring vertically arranged is had in described outer peripheral edges arranged outside, on outer peripheral edges upper surface and inner retainer is provided with sealing gasket 7, described sealing gasket is become three sections by even partition, and Qie Meiduan center is provided with the breach corresponding with described installing hole.Every section of described sealing gasket end is provided with corresponding ladder platform, multistage designs, the convenience that when improve installation, breach is corresponding with installing hole, reduces required precision when processing and installation, adopt faulting of slab ends formula to overlap between two sections simultaneously, improve sealing effectiveness during two sections of connections.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
