Embodiment 1:

Referring to Fig. 5, a kind of open air loudspeaker, including loudspeaker ontology 1, loudspeaker ontology 1 are fixedly connected with earphone cable 2, earphone cable 2 is fixedly connected with headset ontology 3 far from one end of loudspeaker ontology 1, passes through loudspeaker ontology 1, earphone cable 2 and ear Wheat ontology 3 is used cooperatively, and reaches the using effect of outdoor loudspeaker.

Fig. 1-4 is please referred to, the right end of loudspeaker ontology 1 is fixedly connected with a pair of support rods 4, and two support rods 4 are elasticity Shaft 5 provides fixed bracket, is rotatably connected to elastic rotation shaft 5 between two support rods 4, is fixedly connected with card on elastic rotation shaft 5 Buckle 6, the left end of pinch plate 6 is fixedly connected with metal expansion pipe 8, and the position of metal expansion pipe 8 is far from elastic rotation shaft 5, bullet Property shaft 5 allow pinch plate 6 and metal expansion pipe 8 that there is the trend moved downward always, be not easy pinch plate 6 from user It falls off, the compressed spring 7 to match with metal expansion pipe 8, loudspeaker is fixedly connected between pinch plate 6 and metal expansion pipe 8 The right end of ontology 1 dig have with metal expansion pipe 8 match it is anti-be disengaged from the groove 10, by compressed spring 7 and it is anti-be disengaged from the groove 10 cooperation, Even if pinch plate 6 is made to move right a small distance, the compressed spring 7 in compressive state still can be by metal expansion pipe 8 Left end withstand on it is anti-be disengaged from the groove in 10, make loudspeaker ontology 1 be not easy to fall off from the body of staff.

The left end of loudspeaker ontology 1 is fixedly connected with two pairs of limit card slots 11, is connected with and limits in a pair of of limit card slot 11 The deformed spring piece 12 that position card slot 11 matches, deformed spring piece 12 is when loudspeaker ontology 1 is by positive shock, by different Certain deformation occurs itself for shape spring leaf 12, can effectively reduce shock suffered by loudspeaker ontology 1, makes loudspeaker sheet Body 1 is not susceptible to damage, and the upper and lower ends of loudspeaker ontology 1, which are dug, the winding slot 13 being mutually matched, the slot of winding slot 13 Hinge connection has the card line plate 14 to match with winding slot 13 at mouthful, and buckle is connected between card line plate 14 and loudspeaker ontology 1 15, and buckle and 15 be fixedly connected with loudspeaker ontology 1, earphone cable 2 and headset ontology 3 when not in use, winding slot 13 is earphone Line 2 provides the place of winding, is not easy earphone cable 2 at random, knots, and card line plate 14 and buckle 15 then can make earphone cable 2 not Easily fall off out of winding slot 13, metal expansion pipe 8 and it is anti-be disengaged from the groove the silicagel pad 9 for being equipped between 10 and matching with metal expansion pipe 8, And silicagel pad 9 is fixedly connected with metal expansion pipe 8, when silicagel pad 9 can make staff hang over loudspeaker ontology 1 on waistband It is not easy to crush staff.

When needing using loudspeaker ontology 1, earphone cable 2 and headset ontology 3, loudspeaker ontology 1 is hung over into staff Waistband on, only need gently to break pinch plate 6 into two with one's hands at this time, by pinch plate 6 be inserted into staff waistband and waist between, unclamp Pinch plate 6 prevents the insertion of metal expansion pipe 8 to be disengaged from the groove 10 at this point, pinch plate 6 moves downward automatically under the action of elastic rotation shaft 5 It is interior, until compressed spring 7 is equal to the elastic force of elastic rotation shaft 5 itself because of the elastic force that deformation generates, when staff does by a relatively large margin Movement when, pinch plate 6 is pulled out to the right a small distance, is now in the compressed spring 7 of compressive state for metal expansion pipe 8 Push up to the right, be disengaged from the groove the one end of metal expansion pipe 8 far from pinch plate 6 still in 10 also in anti-, make loudspeaker ontology 1 be not easy from Staff falls off with it, after staff replys normality, under the action of elastic rotation shaft 5, and pinch plate 6 and compressed spring 7 It resets, be worn on loudspeaker ontology 1 still can more closely with staff, may be implemented to make hanging loudspeaker It is also not easy to fall off from waistband when staff does biggish movement, is not easy to influence the normal use of loudspeaker.

The preferable specific embodiment of the above, only the utility model；But the protection scope of the utility model is not It is confined to this.Anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its improvement design is subject to equivalent substitution or change, should all cover in the protection scope of the utility model It is interior.
