Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to Fig. 2 to Fig. 6, be the rotatable portable audio amplifier that the utility model provides, be provided with a rotary connection structure in this portable loudspeaker box.Below take this portable loudspeaker box as example, describe rotary connection structure provided by the utility model in detail.
Portable loudspeaker box provided by the utility model, comprise left voice box and right voice box, comprise that also the left shell 1 that can rotate around the pivot 3 in the middle of being positioned at is connected with right shell body and connects left shell 1 and right shell body 2 and make left shell 1 and right shell body 2 can be along the elastic support sheet 4 of the radial rotating of pivot 3, the link of left shell 1 and right shell body 2 is equipped with a spacing breach 11(21), and left voice box is provided with in left shell 1, and right voice box is located in right shell body 2.This portable loudspeaker box can rotate to an angle around the pivot 3 of centre, and this angle is by the spacing breach 11(21 between two audio amplifiers) determine.After audio amplifier was rotated to an angle, the sounding of audio amplifier changed, and sound is as shown in Fig. 3 direction of arrow.Sound conduction direction after change is fit to the demand of the human body sense of hearing more, can access the impression of better tonequality.
Particularly, the left shell 1 of portable loudspeaker box provided by the utility model and the rotatable maximum angle of right shell body 2 and this spacing breach 11(21) relevant, form an angle when the spacing breach 21 of the spacing breach 11 of left shell link and right shell body link joins, this angle is 0 ~ 160 °.When the angle that namely forms between two breach was 160 ° to the maximum, left shell 1 can relatively rotate 160 ° with right shell body 2, and namely between left voice box and right voice box, maximum can be rotated 160 ° relatively.As preferably, in the present embodiment, angle between the spacing breach of left shell 1 and right shell body 2 is 90 °, therefore left shell 1 can relatively rotate 90 ° with right shell body 2, make vertical 90 ° of the voice directions of left voice box 1 and right voice box 2, the sounding track as shown in the direction of arrow of Fig. 3, the sense of hearing of the human body of more fitting.And rotary connection structure provided by the utility model is not only applicable to portable loudspeaker box mentioned in the present embodiment, can also be used for various some products of the anglec of rotation that may need and use.
Particularly, shown in Figure 5, the portable loudspeaker box that provides in the utility model embodiment, left shell 1 and right shell body 2 are cylindrical structural, and both initial conditions are the yi word pattern structure and connect, and take in and carry to facilitate it.And the inside between left shell 1 and right shell body 2 be provided with one can be around the pivot 3 of its rotation.And be provided with the first storage tank 13 in the middle of the link of left shell 1, and be provided with the second storage tank 23 in the middle of the link of right shell body 2, when left shell 1 linked together with right shell body 2, the first storage tank 13 and the second storage tank 23 joined and form a hollow groove.Pivot 3 in the utility model is a cylinder, and pivot 3 is located in described hollow groove.Pivot 3 is not fixedly connected with left shell 1 or right shell body 2 by any connector, be only simply to embed in the hollow groove that forms when the left and right audio amplifier connects, and pivot 3 plays the effect that guides left shell 1 and right shell body 2 to rotate around it.Therefore should be simple in structure, be convenient to also easily realization of processing, be suitable for being widely used.
And left shell 1 and right shell body 2 both can link together, fully fixing by elastic support sheet 4.See also shown in Fig. 4 and Fig. 5-1, this elastic support sheet 4 is provided with an arc spring lamination 41, has respectively the card 42 with left shell 1 or right shell body 2 fasteners in arc spring lamination 41 two ends, the link of left shell 1 is provided with can be for the first cavity 12 of elasticity support chip 4 embeddings, the link of described right shell body 2 is provided with can be for the second cavity 22 of elasticity support chip 4 embeddings, the inwall of the first cavity 12 is provided with can be for the first draw-in groove of card 42 fasteners, and the inwall of the second cavity 22 is provided with can be for the second draw-in groove 221 of card 42 fasteners.Both elastic support sheet 4 be clamped together with left shell 1 and right shell body 2, the card 42 by both sides respectively fasteners in the second draw-in groove 221 of the first draw-in groove of left shell 1 and right shell body 2.In the time of audio amplifier need to being opened, only need left shell 1 with right shell body 2 towards limited location breach 11(21) a side rotate, elastic deformation occurs in the shell fragment 41 of elastic support sheet 4, but still haul left shell 1 and the right shell body 2 of both sides, and this elastic support sheet 4 makes the housing of both sides only can namely rotate around the pivot 3 of centre along the both sides extension of this arc.And this elastic support sheet 4 can guarantee can link together at postrotational left shell 1 and right shell body 2, but is unlikely to and can turns round.In the time of audio amplifier need to being closed, only need left shell 1 with right shell body 2 along the direction reverse rotation of rotation before, this spacing breach 11(21) to open again, this moment, audio amplifier set back.Preferably, angle between this card 42 and shell fragment 41 is between 70 ° ~ 90 °, thereby guarantee after rotating to an angle between left shell 1 and right shell body 2, card 42 still can grab on the draw-in groove of housing, be unlikely to that card 42 comes off in the draw-in groove or housing that elastic support sheet 4 limits both sides can't rotate it.And in the elastic support sheet 4 that provides in the utility model, the angle between card 42 and shell fragment 41 is 80 °.
These are only preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
