Abstract
Embodiment of the present utility model provides a kind of audio amplifier, comprise casing, loudspeaker, a bass horn and an air duct, described loudspeaker is adjacent with bass horn, described audio amplifier also comprises the first loudspeaker division board, the center of described first loudspeaker division board is a loudspeaker hole, described loudspeaker is arranged in described loudspeaker hole, and described first loudspeaker division board comprises a bulge-structure.Can make high pitch and bass horn isolation effect better.
Description
Technical field
The utility model relates to electronic technology field, is specifically related to the technology for loudspeaker box in a kind of electronic technology field.
Background technology
Tradition audio amplifier is all a simple casing composition, comprise casing, loudspeaker, bass horn, usually, the shape of general bass horn can be very large, occupy the position that whole casing is general, this just causes the interval of loudspeaker and bass horn adjacent very near, and the casing in usual loudspeaker face is the design of a plane.Loudspeaker and bass horn will be caused like this when sounding, have overlapping situation at adjacent area, so just cause high pitch bass isolation effect bad.
Utility model content
In view of this, the purpose of this utility model is to make up the deficiencies in the prior art, and the utility model embodiment provides a kind of audio amplifier, can make high pitch and bass horn isolation effect better.
The utility model embodiment realizes like this, a kind of audio amplifier, comprise casing, a loudspeaker, a bass horn, an air duct, described loudspeaker is adjacent with bass horn, and described audio amplifier also comprises the first loudspeaker division board, and the center of described first loudspeaker division board is a loudspeaker hole, described loudspeaker is arranged in described loudspeaker hole, and described first loudspeaker division board comprises a bulge-structure.
Further, described audio amplifier also comprises a mediant trumpet, other while adjacent with bass horn at loudspeaker of described mediant trumpet, described audio amplifier also comprises the second loudspeaker division board, the center of described second loudspeaker division board is a mediant trumpet hole, described mediant trumpet is arranged in described mediant trumpet hole, and described second loudspeaker division board comprises a bulge-structure.
Further, described bulge-structure lower edges is protruding relative to vertical plane along casing.
Further, described projection is an arch projection, and the sagitta of described arch is 0.5cm to 2cm, and described span is 15cm to 30cm.
Further, described projection is an arch projection, and the sagitta of described arch is 0.8cm to 1.5cm, and described span is 20cm to 25cm.
Further, described loudspeaker is magnetic head loudspeaker.
Further, on the casing between described loudspeaker and described bass horn, also comprise a horse race lamp.
Adopt technique scheme, because the existence of loudspeaker division board, make between its loudspeaker and bass horn, to define an isolation, make the sounding of loudspeaker and bass horn have certain isolation effect, make high pitch and bass more clear, mutual interference can not be there is.
Accompanying drawing explanation
The loudspeaker box structure figure that Fig. 1 provides for the utility model embodiment;
The first loudspeaker partition plate structure figure that Fig. 2 provides for the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model embodiment is achieved in that a kind of audio amplifier, comprises casing 1, a loudspeaker 2, a bass horn 3, air duct 4, described loudspeaker 2 is adjacent with bass horn 3, described audio amplifier also comprises the first loudspeaker division board 6, the center of described first loudspeaker division board 6 is a loudspeaker hole 8, and described loudspeaker 2 is arranged in described loudspeaker hole 8, and described first loudspeaker division board 6 comprises a bulge-structure 9.Because the existence of loudspeaker division board, make between its loudspeaker 2 and bass horn 3, to define an isolation, make the sounding of loudspeaker 2 and bass horn 3 have certain isolation effect, make high pitch and bass more clear, mutual interference can not be there is.
As shown in Figure 1, described audio amplifier also comprises a mediant trumpet 5, described mediant trumpet 5 the other of loudspeaker 2 while adjacent with bass horn 3, described audio amplifier also comprises the second loudspeaker division board 7, the center of described second loudspeaker division board 7 is a mediant trumpet hole, described mediant trumpet 5 is arranged in described mediant trumpet hole, and described second loudspeaker division board 7 comprises a bulge-structure 9.
In order to better isolate the sound of loudspeaker 2 and bass horn 3, weakening its overlap, a horse race lamp can also be increased between loudspeaker 2 and bass horn 3.Horse race lamp usually height, about 6 to 8cm, can allow and have an extra better isolation between loudspeaker 2 and bass horn 3.
But it will be understood by those skilled in the art that above-mentioned mediant trumpet 5 on casing 1 not necessarily, possible casing 1 only has the existence of a loudspeaker.Equally, loudspeaker and mediant trumpet can be alt loudspeaker.So above-mentioned loudspeaker be not used in and be only defined as loudspeaker, mediant trumpet is also not only defined as mediant trumpet, the loudspeaker/bass horn mentioned by the utility model embodiment can be loudspeaker, bass horn or alt loudspeaker wherein any one.
As shown in Figure 2, be the three-view diagram of the first loudspeaker division board 6 in above-described embodiment, described bulge-structure 9 lower edges is protruding relative to vertical plane along casing 1.Described projection is an arch projection, and in order to there be an effect of isolating, the sagitta of the arch of protrusion is designed to 0.5cm to 2cm, and according to the size of bass horn 3, the span of arch is 15cm to 30cm.Consideration projection in order to outward appearance is too high neither be seen very well, and projection very little isolation effect is also bad, and the sagitta of arch is designed to as 0.8cm to 1.5cm, and arch span is 20cm to 25cm, and the utility model embodiment is designed to sagitta 1cm, span 22cm.Be appreciated that the structure of the structure of the second loudspeaker division board 7 and the first loudspeaker division board 6 is completely the same, just in the design of bellmouth orifice, need to consider according to the size of concrete loudspeaker.
It will be understood by those skilled in the art that only a projection need be had the two to be done one and effectively isolate, above-described embodiment refer to arch design in order to realize isolation, can also be pane design or other irregular profile design equally.
Above-mentioned loudspeaker 2 or mediant trumpet 5 are magnetic head loudspeaker, magnetic head loudspeaker can be installed from casing 1 inside eaily, the rear, loudspeaker hole 8 of division board is Design of Screw Thread, and magnetic head loudspeaker can directly be locked by screw thread rotation, avoids the outmoded mode of adopting and being screwed.
Adopt technique scheme, because the existence of loudspeaker division board, make between its loudspeaker and bass horn, to define an isolation, make the sounding of loudspeaker and bass horn have certain isolation effect, make high pitch and bass more clear, mutual interference can not be there is.
The foregoing is only embodiment of the present utility model, not in order to limit the utility model, all make within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
