The invention will be further described below in conjunction with accompanying drawing and preferred embodiment.
The present invention discloses a kind of audio amplifier, the horn hood that comprises housing, is arranged on the opening that is used to sound on housing and is used for sealing described opening, embodiment one as audio amplifier of the present invention, as shown in figures 1 and 3, horn hood 2 is fixed on housing one end by bearing pin 21, housing is provided with the axle sleeve 15 that coordinates with bearing pin 21, and described housing is provided with the block piece 11 that raises up at axle sleeve 15 ends, and described horn hood 2 rests on block piece 11 places when opening.
The present invention is provided with the block piece 11 that raises up at axle sleeve 15 ends due to housing, horn hood 2 is fixed on housing by bearing pin 21 and axle sleeve 15, horn hood 2 can rotate by bearing pin 21, horn hood 2 can rely on block piece 11 places when opening horn hood 2, prevent that horn hood 2 from toppling over backward, horn hood 2 just in time is positioned at the center of gravity place, thereby can keep the stability of audio amplifier integral body; And horn hood 2 rests on block piece 11 places when opening and also can reduce horn hood 2 and bearing pin 21 pressurizeds, and then can reduce that it is impaired.
The loudspeaker of audio amplifier of the present invention are arranged in housing, on housing, corresponding loudspeaker position arranges described opening 16 and is used to sound, described opening 16 is circular open, described horn hood 2 can seal described opening 16, and horn hood 2 coordinates opening 16 to arrange, thereby prevent that dust or other booty from falling in audio amplifier or the loudspeaker places, and then prevent that loudspeaker are impaired, guaranteed tonequality, the audio of audio amplifier; Open horn hood 2 when using audio amplifier and get final product, because horn hood 2 is fixed by the axle sleeve 15 on bearing pin 21 and housing, thereby horn hood 2 can rotate by bearing pin 21, is easy to open.
In the present embodiment, be illustrated in figure 1 as the structural representation of described voice box casing, the housing of the described audio amplifier of the present embodiment comprises upper casing and lower casing, Fig. 1 is depicted as the structural representation of the upper casing of described voice box casing, and in conjunction with Fig. 3, Fig. 3 shows the structural representation of described horn hood, wherein, described be used to going out sound opening 16 and be used for being connected with horn hood the axle sleeve 15 that connects cooperation and all be positioned at upper casing, described block piece 11 is perpendicular to housing, block piece 11 is arranged on upper casing and perpendicular to upper casing; Convenient production is set like this, and vertically setting can keep the center of gravity of horn hood 2 not move, and then make the audio amplifier monolithic stability; Certainly, do not move in center of gravity, under the prerequisite of audio amplifier monolithic stability, block piece 11 can be obliquely installed yet.
In the present embodiment, as shown in Figure 1, described housing comprises upper casing and lower casing, upper casing is provided with through hole, and the opening of through hole is described opening 16 be used to going out sound, and described opening 16 is circular, through hole is also circular, thereby be convenient to sound, described axle sleeve 15 is arranged on an end of through hole, in conjunction with Fig. 3, block piece 11 is arranged on axle sleeve 15 ends, axle sleeve 15 between through hole and block piece 11, thereby will rest on block piece 11 when horn hood 2 is opened, so just prevent that horn hood 2 from toppling over backward.
In the present embodiment, as shown in Figure 1, upper casing and lower casing are detachably fixing, and be concrete for being screwed, the screw fixation, and be convenient to dismantle; Described block piece 11 is arranged on the rear end of upper casing; Described block piece 11 tops are provided with screw hole 14, and described lower casing is provided with the screw hole post (not shown) that coordinates with described screw hole 14; 11 places arrange screw hole 14 by screw and the fixing fix tightly solidity that just can strengthen between upper casing and lower casing of lower casing at block piece.Upper casing and lower casing just are screwed and conveniently dismantle, thereby just upper casing and lower casing can be taken apart when the device in voice box casing need to check or keep in repair.The present embodiment upper casing and lower casing also can be fixed by alternate manner, such as connecting and fixing.
The housing of the described audio amplifier of the present embodiment also can be wholely set, and directly block piece is arranged on the axle sleeve place of housing one end.Setting can be saved assembling procedure like this, convenient production.
In the present embodiment, be provided with cavity in housing, concrete is upper casing and lower casing forms fixedly the time, is provided with the cavity that is connected with cavity in housing in described block piece; So just increased the cavity of housing, thereby increased the resonator of loudspeaker, so can increase audio amplifier volume, improve the audio of audio amplifier.
In the present embodiment, as shown in Figure 1, described screw hole 14 is two, is separately positioned on block piece 11 both sides, top; In block piece 11 both sides, screw hole 14 is set and makes good fixing effect.The present embodiment also can arrange the screw hole of other number or screw hole is arranged on other position.
In the present embodiment, as shown in figures 1 and 3, described block piece 11 is used for leaning on the width of horn hood 2 ends greater than the width of the other end; The contact area that increases block piece 11 and horn hood 2 is set like this, makes that to lean on effect better, and small end is set saves material.What described block piece 11 was used for dependence horn hood 2 ends is plane 12, and the other end is the arcwall face 13 that is connected with described plane 12; Block piece 11 rear end faces have certain radian, and block piece 11 rear ends are set does not so just have corner angle, thereby is user-friendly for taking and placing; And good looking appearance, give the visual enjoyment of people.
In the present embodiment, as shown in figures 1 and 3, the height of described horn hood 2 is less than the height of block piece 11; Because the described opening 16 that is used to sound is circle, horn hood coordinates circular open 16 to arrange, thereby the width on horn hood 2 tops is less than the width at middle part, and like this horn hood 2 medium positions being rested on block piece 11 places just increases contact area, and then has increased the stability that leans on.
In the present embodiment, as shown in figures 1 and 3, between described axle sleeve 15 and block piece 11, spacing is arranged, described horn hood 2 tilts to rest on block piece 11; The dependence of tilting prevents that horn hood 2 from dumping forward, thereby has increased the stability that leans on.As can see from Figure 1, certain described spacing is arranged between axle sleeve 15 and block piece 11, this spacing can arrange as required.
Embodiment two as audio amplifier of the present invention, as shown in Figure 2, be that with the difference of embodiment one described audio amplifier lower casing is provided with screw hole, described block piece 11 tops are provided with the screw hole post that coordinates with described screw hole, when the upper casing of audio amplifier and lower casing are screwed, block piece and lower casing also are screwed, and so just can strengthen the fixing fastness between upper casing and lower casing.Arrange so just that screw is exposedly in the bottom of lower casing, and block piece 11 tops do not appear place's screw, thereby just prevent that screw is impaired, and setting can make the voice box casing upper surface smooth like this, and are just more attractive in appearance.Other setting of the present embodiment is identical with embodiment one, tells about no longer one by one here.
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.
