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, comprises housing and loudspeaker, as the embodiment of the invention one, as shown in Figure 1 to Figure 3, described housing is provided with a groove 2, and described loudspeaker are arranged in the described groove 2, and described audio amplifier also comprises an openable horn hood 1 be used to sealing described groove 2; Thereby when not using audio amplifier, horn hood 1 closure is with regard to closed pockets 2, prevent that dust or other foreign material from falling in the groove 2, the loudspeaker impact that just can not be affected or be subject to greatly reduces like this, and then less or make it unaffected on the impact that goes out sound, tonequality or audio of loudspeaker; Open horn hood 1 when needing to use audio amplifier and get final product, convenient, simple, fast.
In the present embodiment, be illustrated in figure 1 as described audio amplifier overall structure schematic diagram, be illustrated in figure 2 as the structural representation of horn hood 1 of described audio amplifier and the structural representation that is illustrated in figure 3 as the housing of described audio amplifier, described horn hood 1 one ends are fixed on the housing, described horn hood 1 and housing are fixing by link, and link makes things convenient for that horn hood 1 is opened, closure; Concrete, fixing by bearing pin 11 between described horn hood 1 and the housing, bearing pin 11 fixations, convenience; More specifically, described bearing pin 11 is arranged on the horn hood 1, and described bearing pin 11 two ends are provided with projection 111, and housing is provided with for the axle sleeve 3 of placing projection 111; Thereby make things convenient for horn hood to rotate by projection 111, and then be convenient to the folding of horn hood 1.Described protruding 111 cooperate with axle sleeve 3, and the cross section of described bearing pin 11 is greater than the opening of axle sleeve 3; Bearing pin 11 is set so just is limited in axle sleeve 3 outsides, avoid bearing pin 11 to enter in the axle sleeve 3 and affect the fixing of horn hood 1, thereby guarantee projection 111 and axle sleeve 3 cooperations.
The described bearing pin of present embodiment also can be arranged on the housing, and described bearing pin two ends are provided with projection, and horn hood is provided with for the axle sleeve of placing projection.Setting can be played approximate effect like this.Yet present embodiment also can be fixed by pin or other structures, is not limited to by bearing pin to be fixed.
In the present embodiment, as shown in Figure 2, described protruding 111 is cylindrical structure, and projection 111 convenient productions of cylindrical structure are convenient to insert in the axle sleeve, and are cooperated firmly; Certainly projection 111 also can be arranged to frustum cone structure or other structures, also can play approximate effect.
As shown in Figure 3, the opening that groove 2 is set on the housing is positioned at the top of housing, described groove 2 ends at loudspeaker bearing downwards from opening part and reduces gradually, loudspeaker are fixed in the groove 2, loudspeaker respective slot 2 arranges, because groove 2 reduces gradually from opening part, and ends at loudspeaker bearing downwards, thereby the propagation that groove 2 facilitates speaker sound is set like this, will be gradually to diffusion all around when sound is upwards propagated.The opening of the described groove 2 of present embodiment is circular, because groove 2 reduces downwards gradually from opening part, and end at loudspeaker bearing, thereby groove 2 also is circular in loudspeaker bearing, then groove 2 is the truncated cone-shaped structure from its opening part to loudspeaker bearing, thereby just make things convenient for the propagation of sound, and make the sound that blazes abroad even.Yet present embodiment originally is not limited to the opening of groove 2 is arranged to circle, rectangle or other shapes also can be set.
In the present embodiment, described housing bottom is provided with the slipmat (not shown), and slipmat prevents that audio amplifier is impaired because of slip, and prevents the voice box casing bottom abrasion.Concrete, described slipmat is two, is separately positioned on the housing two ends, the length of described slipmat cooperates the width setting of housing, and it is convenient that slipmat is set like this, and effective, the width setting of the cooperation housing that slipmat length arranges, thus it is stable that audio amplifier is placed; Described slipmat is bonded in housing bottom by glue, glue fixation, convenience.
Present embodiment can also arrange respectively at the housing bottom two ends circle convex edge, slipmat is fit to the convex edge and arranges and be placed in the convex edge, and the thick height greater than the convex edge of slipmat, bonding or hot melt is fixed in the convex edge slipmat by glue, setting just can increase the bonding area of glue like this, makes fixing more firm.Present embodiment also can arrange the slipmat of other numbers, is not limited to and arranges two.
The described housing of present embodiment is one-body molded up and down, and the housing upper end is large, the lower end is little, arranges like this and can save material, and good looking appearance, gives the visual enjoyment of people.The logical screw of described circuit board is fixed on the housing bottom rear end, thus convenient the placement, and can increase the stability of audio amplifier integral body; In addition, the screw fixation, for convenience detach.
As the embodiment two of audio amplifier of the present invention, be that with the difference of embodiment one described horn hood one end is fixed on the housing, described horn hood and housing are by connecting and fixing; This is horn hood and the fixing another kind of mode of housing, and concrete, described horn hood is provided with the flexible elastic wall of having of two symmetries, and the elastic wall top is respectively equipped with to the salient point of both sides projection, and housing is provided be used to the slot of placing described salient point.Because elastic wall has elasticity, thereby by the elastic deformation of elastic wall is just convenient salient point is placed in the slot, and conveniently salient point is taken out in slot; Horn hood is just convenient like this is connected with housing, also makes things convenient for and takes off horn hood from housing.
In the present embodiment, described housing is provided with the projection that raises up, and described slot is arranged on the projection, slot is arranged the outer just convenient and salient point of outstanding housing to be fixed, because salient point is two, then projection also is two, and the structure of corresponding salient point and position setting.Present embodiment also can arrange inside depression at housing, slot is arranged on the two ends of depression, thereby salient point is placed in the depression first, and then and slot cooperate, same horn hood can rotate by salient point.
The described slot of present embodiment also can replace with through hole, can play approximate effect.
Above content is the further description of the present invention being done in conjunction with concrete preferred implementation, can not assert that implementation 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.
