Description
Technical field
The utility model relates to a kind of horn trumpet.
Background technology
Horn trumpet comprises housing and base, in the cavity of housing and base, be provided with sound-generating element, described sound-generating element comprises coil, static iron core, dynamic iron core and vibrating reed, has certain interval between static iron core and dynamic iron core, under exchange current effect, dynamic iron core drives vibrating reed to vibrate and sounding.Existing horn trumpet has the following disadvantages: one be loudspeaker in use, iron core surface can produce black powder, and the surface that two iron cores are relative is etched gradually, affects the service life of loudspeaker; Two when being the sputterings being subject to water in rainy day environment, and water may enter trumpet from housing, thus affects the sounding of loudspeaker.
Utility model content
The purpose of this utility model is exactly the horn trumpet providing a kind of long service life for above-mentioned situation.The purpose of this utility model realizes by following scheme: a kind of horn trumpet, comprise housing and base, described base is connected by screw with housing, sound-generating element is provided with in the cavity of base and housing, described sound-generating element comprises the coil be located at inside base and the vibrating reed be located on housing, dynamic iron core and static iron core is provided with in coil, one end of described static iron core is connected with base, one end of described dynamic iron core is connected with vibrating reed, gap is had between described static iron core and dynamic iron core, it is characterized in that being provided with the first pourable resin chock on the surface that dynamic iron core is relative with static iron core, the surface that static iron core is relative with dynamic iron core is provided with the second pourable resin chock, owing to being equipped with pourable resin chock on the surface of dynamic iron core and static iron core, iron core surface can be effectively avoided to produce black powder, improve the service life of loudspeaker, water retaining cover is provided with in the front end of housing, described water retaining cover is connected with housing by four pillar stiffeners, the two ends of described four pillar stiffeners are respectively by the edge conjunction of plastic cement and water retaining cover and housing, due to the effect of water retaining cover, rainwater can not enter sound-generating element by housing, thus the sounding of loudspeaker can not be affected.It is simple that the utility model has structure, the features such as long service life.
Accompanying drawing explanation
Fig. 1, the utility model structural representation.
Detailed description of the invention
Fig. 1 is known in contrast, a kind of horn trumpet, comprise housing 1 and base 2, described base is connected by screw with housing, sound-generating element is provided with in the cavity of base and housing, described sound-generating element comprises the coil 3 be located at inside base and the vibrating reed 4 be located on housing, dynamic iron core 5 and static iron core 6 is provided with in coil, one end of described static iron core is connected with base, one end of described dynamic iron core is connected with vibrating reed, gap is had between described static iron core and dynamic iron core, it is characterized in that being provided with the first pourable resin chock 7 on the surface that dynamic iron core is relative with static iron core, the surface that static iron core is relative with dynamic iron core is provided with the second pourable resin chock 8, water retaining cover 9 is provided with in the front end of housing, described water retaining cover is connected with housing by four pillar stiffeners 10, the two ends of described four pillar stiffeners are respectively by the edge conjunction of plastic cement and water retaining cover and housing.
