Description
Technical field
The utility model relates to audio amplifier, particularly relates to a kind of slim type portable audio amplifier.
Background technology
Portable loudspeaker box, also claims portable audio, and mainly comprise for generation of the signal source (CD/MP3) of audio signal and the loud speaker for sending sound wave, signal source and loud speaker are contained with in housing.Along with the development of technology, the functional of portable loudspeaker box strengthens gradually, and as accepted Bluetooth signal broadcast, receive data etc. by USB port, volume is also more and more less along with the needs be convenient for carrying.
Particularly, the housing that general portable loudspeaker box comprises fore shell, back cover consists of screw fastening, is provided with loudspeaker, pcb board, airduct in housing, fore shell has the opening exported for loudspeaker, and fore shell is coated with iron net for dust-proof, iron will install nameplate by the clubfoot design that bathes one's feet in hot water on the net; For providing shockproof properties, the back cover of hard will be set with flexible glue, and cross section is that circular airduct adopts the mode of fastened by screw to be fixed on fore shell.This structure will cause assembling loaded down with trivial details, and production efficiency is low, and cost of labor is high, and audio amplifier finished product is thicker, is unfavorable for carrying also attractive in appearance not.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of slim type portable audio amplifier, and energy improving production efficiency, reduces costs, and forms overall thinner structure simultaneously.
The purpose of this utility model realizes by the following technical solutions:
A kind of slim type portable audio amplifier, comprise fore shell, back cover, loudspeaker, pcb board, iron net and airduct, back cover comprises the ebonite shell that double-shot moulding is formed and the soft gel coat be coated on outside this ebonite shell, fore shell is fastened on ebonite shell, pcb board and loudspeaker are all placed in fore shell and ebonite shell encloses in the accommodation space of formation, and iron net is covered in fore shell; Airduct is cross section is semicircular barrel, and the notch of this airduct is covered in the back side of fore shell.
Preferably, described slim type portable audio amplifier also comprises nameplate, and iron has the opening penetrated for nameplate on the net, and nameplate is pasted on before fore shell through after opening.
Preferably, the back side evagination of fore shell is formed with two raised lines, each raised line has the slot that the notch edges for airduct is inserted.
Preferably, fore shell has the first installing port penetrated for loudspeaker, and pcb board is fixed in the ebonite shell of back cover, this pcb board has for forming the second spacing installing port to loudspeaker.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model is by the mode of double-shot moulding, soft gel coat and ebonite shell are made same back cover, to save the operation of extra suit flexible glue, in combination with the manner of the ebonite shell of fore shell and back cover, greatly improve production efficiency, save cost of labor, material cost; In addition, by being pasted onto the mode of fore shell with nameplate, also saving operation further, improve production efficiency further; More crucial, cross section is the thickness that semicircular airduct can reduce accommodation space greatly, the integral thickness of this audio amplifier is minimized, is beneficial to carry, simultaneously also more attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the cutaway view of a kind of slim type portable audio amplifier of the utility model;
Fig. 2 is the exploded view of a kind of slim type portable audio amplifier of the utility model.
In figure: 1, fore shell; 11, raised line; 111, slot; 12, the first installing port; 2, back cover; 21, ebonite shell; 22, soft gel coat; 3, loudspeaker; 4, pcb board; 41, the second installing port; 5, iron net; 51, opening; 6, airduct; 61, notch; 7, nameplate.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
A kind of slim type portable audio amplifier as shown in Fig. 1 ~ 2, comprise fore shell 1, back cover 2, loudspeaker 3, pcb board 4, iron net 5 and airduct 6, back cover 2 comprises the ebonite shell 21 that double-shot moulding is formed and the soft gel coat 22 be coated on outside this ebonite shell 21, fore shell 1 is fastened on ebonite shell 21, pcb board 4 and loudspeaker 3 are all placed in fore shell 1 and ebonite shell 21 encloses in the accommodation space of formation, and iron net 5 is covered in fore shell 1; Airduct 6 for cross section be semicircular barrel, the notch 61 of this airduct 6 is covered in the back side of fore shell 1.
By the mode of double-shot moulding, soft gel coat 22 and ebonite shell 21 are made same back cover 2, to save the operation of extra suit flexible glue, in combination with the manner of fore shell 1 with the ebonite shell 21 of back cover 2, greatly improve production efficiency, save cost of labor, material cost.Wherein, pcb board 4 as the signal source of audio signal, by the audio signal that sends through loudspeaker 3 playing sound.Fore shell 1 and ebonite shell 21 enclose the accommodation space of formation for the protection of pcb board 4, arm-tie and airduct 6.Cross section is the thickness that semicircular airduct 6 can reduce accommodation space greatly, the integral thickness of this audio amplifier is minimized, is beneficial to carry, simultaneously also more attractive in appearance.
As preferred embodiment, this slim type portable audio amplifier also comprises nameplate 7, iron net 5 has the opening 51 penetrated for nameplate 7, and nameplate 7 is pasted on before fore shell 1 through after opening 51.Opening 51 pairs of nameplates 7 form certain position-limiting action, nameplate 7 are able to after being pasted onto fore shell 1 more firm, realize stickup effect by 3M glue.
More stable fixing for being formed airduct 6, the back side evagination of fore shell 1 is formed with two raised lines 11, each raised line 11 has the slot 111 that notch 61 edge for airduct 6 inserts.Specifically carry out erection & lift stability by ultrasonic fusing.After notch 61 edge of airduct 6 inserts slot 111, will the cavity sealing and enclose be formed, both can obtain being the effect that circular airduct 6 is identical with common cross section, and play inverting function, can acoustic short circuit be prevented, the thickness of accommodation space can be reduced again.
