During moving-coil speaker work, the wire of voice coil loudspeaker voice coil winding has electric current to pass through, and 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 centring disk 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, guarantee voice coil loudspeaker voice coil winding part can be in magnetic gap proper motion and deflection does not occur.
Wall-hanging loud speaker peculiar to vessel is as a kind of concrete application of loud speaker, it generally consists of loud speaker and box body, box body conventionally adopts and is comprised of the front shroud being threaded and bonnet, loud speaker is fixedly installed on box body inside, but because moist on ship, existing wall-hanging loud speaker humidity resistance peculiar to vessel is poor, and adopt screw to connect front and rear covers, processing inconvenience, but also can cause dismounting inconvenience because screw gets rusty.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of facility and good wall hanging loud speaker peculiar to vessel of humidity resistance assembled is provided.
For realizing the technical scheme that the purpose of this utility model adopts, be:
A kind of wall hanging loud speaker peculiar to vessel, comprise the box body being made of plastics and the loud speaker that is fixedly installed box body inside, described loud speaker comprises basin frame, vibrating diaphragm and dust cover, described box body is comprised of front shroud and bonnet, described front shroud comprises front panel and the sidewall being integrally formed with described front panel, in described bonnet, be formed with respectively a plurality of spaced support columns side ring week, a side at described bonnet is inwardly vertically provided with connecting plate highlightedly simultaneously, in described outside, connecting plate end, be formed with hook, on the sidewall of described front shroud, be formed with accordingly the location hole corresponding with described hook.
Described front panel and bonnet are rectangular configuration, and described bonnet surrounding is respectively arranged with support column, and described connecting plate is arranged on Width and is positioned in the middle of two support columns.
On described bonnet, be fixedly installed seal washer with the sidewall corresponding position of described front shroud.
The basin frame front side of described loud speaker is fixedly installed sealing ring.
On described speaker frame, be formed with location hole, described sealing ring one side is formed with the projection mating with described location hole, and described location hole matches that with described projection described sealing ring is fixedly connected with basin frame.
The cone surface of described loud speaker scribbles marine glue, and the coating layer thickness of described marine glue is 0.08-0.12mm.
The cone of described loud speaker and dust cover are MYLAR material.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has improved the mounting means that front shroud is used screw to be connected with bonnet, uses the cooperation of self-locking hook and support column, can quickly and easily front shroud, bonnet be combined, time saving and energy saving, and makes outward appearance more attractive in appearance.
As preferred version, being respectively arranged with hermetically-sealed construction between described bonnet and front shroud and between basin frame and front shroud, after assembling completes, can keep the integral sealing effect of box body, effective anti-sealing enters.
Accompanying drawing explanation
Figure 1 shows that wall hanging loud speaker cross section structure schematic diagram peculiar to vessel of the present utility model;
Figure 2 shows that rear cover structure schematic diagram.
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 is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, 2, wall hanging loud speaker peculiar to vessel of the present utility model comprises box body and the loud speaker being made of plastics, described loud speaker comprises taper basin frame, vibrating diaphragm and dust cover etc., described box body is comprised of front shroud 1 and bonnet 2, described front shroud comprises front panel and the sidewall being integrally formed with described front panel, described front panel and partial sidewall and described corresponding position, loud speaker installation position offer that tipper is done so that sound transmission out, tipper design is unfavorable for that water enters, and has also strengthened attractive in appearance simultaneously.In described bonnet, be formed with respectively a plurality of spaced support columns 3 side ring week, a side at described bonnet is inwardly vertically provided with connecting plate 4 highlightedly, in described outside, connecting plate end, be formed with hook 5, on the sidewall of described front shroud, be formed with accordingly the location hole corresponding with described hook 6, utilize hook and location hole to form self-locking hook, assembling convenience is greatly improved, and has save the use of screw simultaneously, has also avoided corrosion.
