The free end of the first rotating wing is pivoted with the second rotating wing. When the portable sound box is used, the second rotating wing can be spread to reflect sound sent from the loudspeaker for improving the stereophonic effect of sound field; when the portable sound box isn't used, the second rotating wing can rotatablely cover the first rotating wing for protecting the loudspeaker.
Description
[affiliated technical field]
The utility model relates to a kind of audio amplifier, particularly a kind of portable loudspeaker box that can fold.
[background technology]
Along with improving constantly of people's quality of life, the consumer wishes can both enjoy interesting to listen to music whenever and wherever possible.So walkman, the music player of miniaturizations such as MP3 arises at the historic moment, and uses earphone to listen to but this music player mainly is adapted to the individual.If in small-sized open air party, share music, just must use external portable loudspeaker box.Existing portable loudspeaker box mainly is that two sound channels are reduced music about dividing by two independently little audio amplifiers, and its advantage is opening very much of can separating of left and right acoustic channels, can produce sound field effect preferably; But it is too big that weak point is a volume, and independently audio amplifier is inconvenient to load and transport or carry.Therefore portable loudspeaker box that two independent audio amplifiers are combined has appearred in industry, and it mainly utilizes Telescopic handle to connect two audio amplifiers, changes the distance of two audio amplifiers by the length of adjusting pull bar, and relevant patent is as No. 92212092.7 patent of China.But this loudspeaker box structure more complicated, and volume benevolence so seems big slightly; So a kind of Foldable cellular audio amplifier has further appearred again in industry, its main feature be about two sound equipments can be fastened on main frame behind, to reduce volume, be convenient for carrying, but these foldable audio amplifiers can not produce good sound field effect, its main cause is because the audio amplifier volume is less, so the distance between the loud speaker of left and right acoustic channels is closer, sound field separating degree to left and right acoustic channels is not very high like this, can not produce good stereophonic effect, relevant patent is as No. 96237746.5 patent of China.
[summary of the invention]
The purpose of this utility model is to provide a kind of portable loudspeaker box, and not only volume is small and exquisite for it, and can produce good stereophonic effect.
The technical scheme that its technical problem that solves the utility model adopts is: this portable loudspeaker box has a power supply holding part, a pair of first rotation wing and a pair of second rotation wing.This power supply holding part top is provided with a lid, can hold 2 joints or 4 joint alkaline dry batteries under it.The dead astern of power supply holding part is provided with a pair of protruding button portion.These power supply holding part both sides are respectively equipped with a pivoted hole, articulate the one first rotation wing on this pivoted hole, and it is one tabular that this first rotation wing roughly is, and its outer end is respectively equipped with one first casing.This first casing front is provided with an opening and a voice guide hole.First box house at this opening part is equipped with a miniature loudspeaker; This inboard, first casing back is respectively equipped with a recessed button portion.This first rotation wing free end articulates the one second rotation wing.When using this portable loudspeaker box, the deployable sound that sends from loud speaker that reflects of its second rotation wing is to increase the stereophonic effect of sound sound field; When not using this portable loudspeaker box, this first rotation wing is fastened on power supply holding part both sides collapsibly, and this second rotation wing rotatably covers on the first rotation wing, with the protection loud speaker.When these two the first rotation wings when combining, it can be surrounded the power supply holding part, and the protruding button portion of the recessed button portion that utilizes first casing and the rear end of power supply holding part matches audio amplifier is folded.
The beneficial effects of the utility model are, this portable loudspeaker box not only volume is small and exquisite, collapsible being easy to carry, and can produce better sound field effect, and good looking appearance.

[embodiment]
Please together consult Fig. 1 and Fig. 2, the utility model portable loudspeaker box 10 has a power supply holding part 20, a pair of first rotation wing 30 and a pair of second rotation wing 40.
This power supply holding part 20 roughly is cube, and its top is provided with a lid 22, and this lid 22 can being fastened on the power supply holding part 20 by a pair of first buckle, 23 raising types.These lid 22 belows have 4 spaces 25, can hold an alkaline dry battery (figure does not show) in it respectively.The front panel 24 of this power supply holding part 20 is provided with a mains switch 26, one power supply indicators 27 and a volume switch 28, and the control circuit board of device (figure does not show) links so that portable loudspeaker box 10 is controlled in these switches and the power supply holding part 20.Front panel 24 both sides of this power supply holding part 20 are respectively equipped with a pair of pivot joint mouthful (figure does not show).The dead astern of this power supply holding part 20 is provided with a pair of protruding button portion 29, and these protruding button portion 29 belows pick out an audio signal wire 50 from power supply holding part 20 inside.
This first rotation wing 30 roughly is one tabular, the one side is provided with a relative pin clamp (figure does not show) and a drive-connecting shaft (figure does not show), drive-connecting shaft can be inserted into one and articulate in the mouth, utilize a latch (figure do not show) again thereby from pin clamp, insert and articulate mouth and cooperatively interact the first rotation wing 30 is articulated on the power supply holding part 20 with another, synchronous signal line 52 passes from this pin clamp and pivot joint mouth, and this first rotation wing 30 can and articulate the mouth cooperation place along this drive-connecting shaft and rotate 0 °～180 °; The free end of its another side is provided with one first casing 34, and the front surface of this first casing 34 is provided with a speaker openings 36, and its below is provided with a voice guide hole 37.A miniature loudspeaker 35 is installed in inside at first casing 34 at these speaker openings 36 places.The inboard, back of this first casing 34 is respectively equipped with a recessed button portion 39, and it can cooperatively interact with the protruding button portion 29 that power supply holding part 20 dead asterns are provided with.
