Embodiment
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment.
The present invention discloses a kind of audio amplifier, comprise loudspeaker, housing, be arranged on the opening that is used to sound on housing and an end is fixed on the horn hood that is used for sealing described opening on housing, as depicted in figs. 1 and 2, described loudspeaker are adhesively fixed on housing by glue, and described housing is provided with the stopping means for spacing fixedly loudspeaker.The present invention more firmly is fixed on housing loudspeaker due to the stopping means that is provided with on housing for spacing fixedly loudspeaker, thereby prevents that loudspeaker are loosening, guarantees its normal operation.
In the present embodiment, described housing comprises upper casing and lower casing, and described stopping means is arranged on upper casing, and loudspeaker are by be adhesively fixed stopping means place between upper casing and lower casing of glue, to guarantee the loudspeaker normal operation.Be illustrated in figure 1 as the structural representation of described housing, concrete is the structural representation of upper casing, described upper casing is provided with through hole 11, it is described that to go out the sound opening be via openings, described through hole 11 is manhole, circular through hole 11 facilitates the propagation of sound, makes the sound that blazes abroad even, and circular convenient production of through hole 11.Be extended with an extension 12 downwards along through hole 11, described extension 12 upper ends are large, the lower end is little, and described stopping means is arranged on extension 12 bottoms.Through hole 11 is circular, and extension 12 is frustum cone structure, reduces gradually from top to bottom, and then is conducive to sound and outwards enlarges gradually spread scope.
As shown in Figure 1, described stopping means comprises retainer plate 13 and spacing collar 14, and is specific as follows.
In the present embodiment, in conjunction with shown in Figure 2, described stopping means comprises a retainer plate 13, described retainer plate 13 forms around extension base plane inwardly protruding, the loudspeaker opening edge along being provided with a circle outside convex edge, is the first convex edge 21, and described the first convex edge 21 is placed on retainer plate 13 places, thereby increase the contact area between loudspeaker and housing, make fixing more firm.Described through hole 11 is manhole, and described extension 12 is frustum cone structure, thereby described retainer plate 13 is circular, arranges like this sound that blazes abroad is evenly propagated to surrounding, and facilitates and loudspeaker are fixed.
Stopping means also comprises a spacing collar 14, described spacing collar 14 convexes to form to downward-extension along extension 12 base plane, the internal diameter of described spacing collar 14 is more than or equal to the external diameter of the first convex edge 21, spacing collar 14 is set with loudspeaker the first convex edge 21 placements within it, thereby the first convex edge 21 is spacing in spacing collar 14, prevent that loudspeaker from rocking, loudspeaker are fixedly played good effect.The height of described spacing collar 14 makes the first convex edge 21 be positioned at spacing collar 14 fully, thereby can strengthen spacing effect more than or equal to the thickness of the first convex edge 21.Described spacing collar 14 is also circular.
In the present embodiment, as depicted in figs. 1 and 2, described loudspeaker are adhesively fixed on retainer plate 13 and spacing collar 14 by glue, before comparing, loudspeaker directly are adhesively fixed on upper casing by glue, increased the fixed-area between loudspeaker and upper casing, glue not only is bonded on retainer plate, also is bonded on spacing collar, thereby greatly increased bond area, strengthened fixed effect.
In the present embodiment, as shown in Figure 2, Fig. 2 shows the structural representation of described loudspeaker, and described loudspeaker opening edge is along a convex edge that makes progress is set, it is the second convex edge 22, the second convex edge 22 extends upward formation along the loudspeaker edges, and along vertical, and the external diameter of the second convex edge 22 is less than the external diameter of the first convex edge 21 with first protruding 21 in the second convex edge 22, in conjunction with Fig. 1, arrange on loudspeaker in the extension 12 that the second convex edge 22 is placed on through hole 11, not only can strengthen the fixed effect of loudspeaker, also facilitate loudspeaker to go out sound.The external diameter of described the second convex edge 22 is equal to or less than the internal diameter of retainer plate 13, arranges like this to guarantee that the second convex edge 22 is placed in the extension 12 of through hole 11.
In the present embodiment, described horn hood is fixed on housing by an end and seals out the opening of sound, gets final product thereby open horn hood when needing to use audio amplifier, and when not using, closed horn hood has just prevented that dust or other foreign material from falling in audio amplifier.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
