Abstract
The utility model discloses a kind of audio amplifier, comprise audio amplifier fore shell (1), audio amplifier back cover (2) and loudspeaker, the outstanding limit of Loudspeaker diaphragm (31) is arranged at the front frame end face of horn bracket (32), by described horn bracket (32) by described loudspeaker be placed in described audio amplifier fore shell (1) front, center through hole along on limit, in described audio amplifier back cover (2), middle part arranges fore-set (21), on the yoke of described loudspeaker (33), post elastic cushion (34), after the assembling of described audio amplifier fore shell (1) and described audio amplifier back cover (2), described fore-set (21) holds out against described loudspeaker yoke (33) and compresses described loudspeaker and be fixed on described audio amplifier fore shell (1), the outstanding limit pressurized of described Loudspeaker diaphragm (31) is about to described loudspeaker and described audio amplifier fore shell (1) sealing simultaneously.Compared with prior art, thereby the utility model assembling time does not need a large amount of glue that cost is reduced significantly, and easy to assembly, efficiency is high.
Description
Technical field
The utility model relates to a kind of audio amplifier.
Background technology
Audio amplifier generally comprises audio amplifier fore shell, audio amplifier back cover and loudspeaker.How as shown in Figure 1 current common loudspeaker box structure, audio amplifier fore shell 1a front, center arranges to be with along through hole in order to loudspeaker to be installed, horn bracket 32a is placed in this through hole along on limit, then at horn bracket 32a and audio amplifier fore shell 1a contact position, add glue bonding, after glue layer 4 solidifies, again audio amplifier fore shell 1a and audio amplifier back cover 2a are assembled, finally complete the assembling of audio amplifier.Due to needs glue bonding, for fear of glue, hang contacting of limit with Loudspeaker diaphragm 31a, before horn bracket 32a, frame need arrange rib.The defect of prior art is: 1) horn assembled is used a large amount of glue operations, and gluing operating efficiency is not high; 2) number of glue amount, employee's operation gimmick directly affects the sealing effectiveness of audio amplifier; 3) glue assembling operation, needs four hours above curing times, and the audio amplifier production cycle is long.
Summary of the invention
Problem to be solved in the utility model is the defect that overcomes above-mentioned prior art, and a kind of novel structure is provided, and during the assembling of this audio amplifier, does not need glue can make cost be reduced significantly, and easy to assembly, efficiency is high.
The technical solution of the utility model is: the utility model comprises audio amplifier fore shell, audio amplifier back cover and loudspeaker, the outstanding limit of Loudspeaker diaphragm is arranged at the front frame end face of horn bracket, by described horn bracket by described loudspeaker be placed in described audio amplifier fore shell front, center through hole along on limit, in described audio amplifier back cover, middle part arranges fore-set, on the yoke of described loudspeaker, post elastic cushion, after the assembling of described audio amplifier fore shell and described audio amplifier back cover, described fore-set holds out against described loudspeaker yoke and compresses described loudspeaker and be fixed on described audio amplifier fore shell, the outstanding limit pressurized of described Loudspeaker diaphragm is about to described loudspeaker and the sealing of described audio amplifier fore shell simultaneously.
Described fore-set is cross fore-set.
Described elastic cushion is sponge.
Described audio amplifier fore shell and described audio amplifier back cover adopt ultrasonic fusing assembling.
The beneficial effects of the utility model are: of the present utility model in audio amplifier back cover middle part fore-set is set, on the yoke of loudspeaker, post elastic cushion, before horn bracket, frame is cancelled rib simultaneously, the outstanding limit of Loudspeaker diaphragm is arranged at the front frame end face of horn bracket, by horn bracket by loudspeaker be installed on audio amplifier fore shell center through hole along on limit, then assemble audio amplifier back cover, the fore-set of audio amplifier back cover holds out against loudspeaker yoke and compresses loudspeaker and be fixed on audio amplifier fore shell, simultaneously, the outstanding limit of Loudspeaker diaphragm is about to loudspeaker and the sealing of audio amplifier fore shell by compression, elastic cushion also plays shock absorbing effect.Horn assembled technique is simple, easy to operate, thereby has improved efficiency, and has shortened widely the production cycle of audio amplifier; Compared with prior art, save glue cost, reduced gluing station, reduced cost of labor.
Accompanying drawing explanation
Fig. 1 is the loudspeaker box structure schematic diagram of currently available technology;
Fig. 2 is loudspeaker box structure schematic diagram of the present utility model;
Fig. 3 is the structural representation of the utility model audio amplifier back cover.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made to concrete detailed description.
As Fig. 2, shown in Fig. 3, audio amplifier described in the utility model comprises audio amplifier fore shell 1, audio amplifier back cover 2 and loudspeaker, the outstanding limit of Loudspeaker diaphragm 31 is arranged at the front frame end face of horn bracket 32, by horn bracket 32 by loudspeaker be placed in audio amplifier fore shell 1 front, center through hole along on limit, the interior middle part of audio amplifier back cover 2 arranges cross fore-set 21, on the yoke 33 of loudspeaker, post elastic cushion 34, the utility model elastic cushion 34 is sponge, audio amplifier fore shell 1 and audio amplifier back cover 2 adopt ultrasonic fusing assembling, after assembling, fore-set 21 holds out against loudspeaker yoke 33 and compresses loudspeaker and be fixed on audio amplifier fore shell 1, the outstanding limit of Loudspeaker diaphragm 31 is about to loudspeaker and 1 sealing of audio amplifier fore shell by compression simultaneously, sponge also plays shock absorbing effect.
Compared with prior art, audio amplifier of the present utility model has the glue of needs, has saved glue cost, reduces gluing station, reduces cost of labor; Simple for assembly process, easy to operate, thus efficiency improved, and shortened widely the production cycle of audio amplifier.
