Specific embodiment

The utility model portable telescopic Bluetooth audio device is made further specifically with reference to the accompanying drawings and detailed description It is bright:

As shown in Figure 1, Figure 2 and Figure 3, in this embodiment, the utility model portable telescopic Bluetooth audio device, including Pedestal 30, box body 20, lower sound cylinder 12, upper sound cylinder 11 and loudspeaker 19.Pedestal 30 is for Nian Jie with the mobile phone shell back side, by two-sided Bonding can be realized in glue；Equipped with iron plate 32 on the surface that pedestal 30 and mobile phone shell fit, on the surface not being bonded with mobile phone shell Equipped with groove 33；Box body 20 is provided with bluetooth module and the battery for powering to loudspeaker 19, these at present for all For the conventional prior art, application is highly developed, therefore details are not described herein；20 lower part of box body is in groove 33, box body 20 Intracavity bottom be fixedly installed with four the first magnet 24 for being attracted iron plate 32, week of four the first magnet 24 along iron plate 32 Circle is uniformly distributed, and by the suction between the first magnet 24 and iron plate 32, realization box body 20 is reliably connected with pedestal 30；Lower sound 12 bottoms of cylinder are fixedly mounted on the top surface of box body 20；11 sets of upper sound cylinder outside lower sound cylinder 12, the bottom edge of upper sound cylinder 11 Place is equipped with the lower annular convex edge 14 of inside bending, and the top edge of lower sound cylinder 12 is equipped with the upper annular convex edge 13 of outside bending, By the mutual overlap joint of upper annular convex edge 13 and lower annular convex edge 14, to block lower annular convex edge 14 from lower 12 top of sound cylinder Abjection；Loudspeaker 19 is fixedly mounted on sound cylinder 11 by mask 10, equipped with flexible fixed between upper sound cylinder 11 and lower sound cylinder 12 Position mechanism, to realize upper sound cylinder 11 along the axial stretching of lower sound cylinder 12.

Referring to fig. 2, Fig. 3 and Fig. 4, above-mentioned Telescopic positioning device are specifically used such as flowering structure: the fixed peace in the top of box body 20 It is used for second magnet 25 attracted with 19 bottom magnet of loudspeaker equipped with one, the inner wall of upper sound cylinder 11 to be equipped with vertical cutting 17, the top surface of upper annular convex edge 13 is equipped with left block 16 and right block 18, and for the guiding for vertical cutting 17 insertion Hole 131, left block 16 and right block 18 are located at the left and right sides of pilot hole 131, and left block 16 sticks on pilot hole 131 Place.

When playing audio, by pulling up upper sound cylinder 11 with hand, it is axially moved it along lower sound cylinder 12, thus Sound chamber is surrounded between upper and lower sound cylinder and mask；Instantly when annular convex edge 14 and upper annular convex edge 13 fit, vertical cutting 17 is just Good to deviate from out of pilot hole 131, the edge of pilot hole 131 is equipped with guiding slope 132, is oriented to slope 132 close to right block 18 Guiding is played the role of in side；The sound cylinder 11 in own axes fine rotation, vertical 17 bottom of cutting is on guiding slope 132 Under effect, 13 top surface of annular convex edge is slided in fitting, when right block 18 is touched in vertical cutting 17 (state shown in Figure 4), It is rotated in place；Between vertical cutting 17 and upper annular convex edge 13 under the action of pretightning force, upper sound cylinder 11 will not be retracted voluntarily.This When, mobile phone is placed on desk, audio is played by loudspeaker 19, and the upper sound cylinder 11 stretched out can be used as mobile phone branch at this time Frame come using.When not playing audio, opposite direction slightly rotates sound cylinder 11, when left block 16 is touched in vertical cutting 17, erects It is located just at the surface of pilot hole 131 to cutting 17, pushes down on sound cylinder 11, sound chamber starts zooming out, when 19 bottom of loudspeaker When the magnet in portion is attracted the second magnet 25, the contraction (state shown in Figure 5) of sound cylinder 11 in completion, in the effect of magnet suction Under, upper sound cylinder 11 will not be skidded off voluntarily from lower sound cylinder 12；The diminution of volume so that the utility model carry it is very convenient.

In order to play buffer function, when preventing sound cylinder 11 in drawing, lower annular convex edge 14 is directly hit with upper annular convex edge 13 It hits, the utility model is equipped with sealing ring 15 between upper annular convex edge 13 and lower annular convex edge 14；In addition to this, the sealing ring 15 also act as the effect of sealing, prevent steam from entering sound intracavitary.

When being not necessarily to the utility model Bluetooth audio device, directly box body 20 can be extracted from groove 33, to only be left pedestal 30 is Nian Jie with mobile phone shell, at this point, carrying for the convenience of the users to mobile phone, the utility model is right on the top surface of pedestal 30 Claim hingedly there are two U-shaped pull rings 31 to insert a finger into pull ring and carry to mobile phone by cocked two U-shaped pull rings 31.

Compared with prior art, the utility model has the advantages that

1, it is designed by the structure for the sound chamber that stretches, so that the person of being convenient to use is to this reality while guaranteeing acoustical quality With novel carrying；

2, after upper sound cylinder 11 stretches out, other than it can play audio, can also come as handset bracket using realization is blue The combination of tooth sound equipment and handset bracket；

3, in this embodiment, both more than two upper sounds can also be used using a upper sound cylinder 11 Cylinder 11 (attached drawing shows the connection structures of two upper sound cylinders 11), by the flexible of upper sound cylinder 11, thus realize different length and The not variation of unisonance chamber volume；As for how many upper sound cylinders 11 are used, can specifically determine according to actual needs；Under normal circumstances, Sound cylinder 11 on one or two, along with the sound chamber that a lower sound cylinder 12 is surrounded can meet the requirement of actual use.In increase When sound cylinder 11, used stretching structure is identical as the structure of above-mentioned Telescopic positioning device, and those skilled in the art are in conjunction with attached drawing And the description of this specification word segment can easily be implemented, therefore do not repeat excessively herein.

Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this The various changes and improvements that the technical solution of utility model is made should all be fallen into the protection scope of the utility model.
