Abstract

The utility model discloses an extendable and bendable sound box, comprising a sound box body (1), an operation control box (2), and an extendable folding part (3) arranged between the sound box body (1) and the operation control box (2). The utility model is characterized in that the extendable folding part (3) comprises an upper flanging (4) and a lower flanging (5), which are connected to form folded wrinkles; the section of the upper flanging (4) is shaped like an arc line, and the section of the lower flanging (5) is shaped like a straight line; and the arc line length (L1) of the section of the upper flanging (4) is greater than the direct line length (L2) of the section of the lower flanging (5). No matter the container is in an unfolded state, folded state, or a bent state, the utility model completely overcomes the rebounding effect caused by the natural tension of the material due to the function of the upper line shaped upper flanging. Therefore, the arc line shape of the upper flanging of the container keeps the extended, folded or bent state unchangeable. The utility model has the advantages of convenient use, non-deformed shape, good application effect, etc, and folding of the utility model does not cause rebounding.

Description

A kind of retractable curved audio amplifier

Technical field:

The utility model relates to a kind of retractable curved audio amplifier, belongs to the audio amplifier technical field.

Background technology:

Audio amplifier in the market is a lot, and the connected mode between these audio amplifiers all is the not flexible bending fixed usually, and is not too convenient sometimes when making the user use audio amplifier.

Summary of the invention:

The purpose of this utility model is: provide a kind of flexible audio amplifier easy to use, can be arbitrarily crooked, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: it comprises sound box bodies (1), middle control case (2), and between sound box bodies (1) and middle control case (2), be provided with telescopic folded part (3), it is characterized in that: telescopic folded part (3) is interconnected to folding pattern by upper hem (4) and lower hem (5) and forms, the cross sectional shape of its upper hem (4) is the circular arc line shape, the cross sectional shape of lower hem (5) is a rectilinear form, and the cross sectional shape of upper hem (4) is that the arc length L1 of circular arc line is the straight length L2 of straight line greater than the cross sectional shape of lower hem (5).

The cross sectional shape of upper hem (4) is that the cross sectional shape of the arc length L1 of circular arc line and lower hem (5) is that the ratio of the straight length L2 of straight line is: L1: L2=1.15～1.30.

Folded part (3) is circular or oval.

The folding pattern that is interconnected to the telescopic folded part 3 that folding pattern forms by upper hem (4) and lower hem (5) has 3～20 roads.

Folded part (3) adopts plastic material making such as polypropylene plastics.

Can set up functional devices as required on the middle control case (2).

Because the motion of folded part (3) needs to contact with air, therefore can be placed on folding required pore (6) on sound box bodies (1) or middle control case (2) or the folded part (3) as required.

Its power supply can adopt at middle control case (2) mode that battery case uses battery is set, and also can adopt the USB output socket that sets up standard to utilize the mode of computer USB power supply.

Owing to adopted technique scheme, the utility model is made as the circular arc line shape to the cross sectional shape of the upper hem of telescopic folded part (3), the cross sectional shape of its lower hem is made as rectilinear form, and the cross sectional shape that makes upper hem is that the arc length of circular arc line is the straight length of straight line greater than the cross sectional shape of lower hem, adopt this structure, when holding audio amplifier with this folded part (3) when drawing back, because the effect of the circular arc line arcuate in shape of its upper hem, overcome the rebound effect that natural tension force produced of material fully, therefore, in the effect of the circular arc line arcuate in shape of upper hem state to be drawn back in maintenance constant for container; When the pushing audio amplifier folds contraction with this folded part (3), its lower hem shrinks in the circular arc line arch of upper hem into, the upper hem of this circular arc line arch can overcome the rebound effect that natural tension force produced of its material effectively, and therefore, folded part (3) will keep folding contraction state constant.In addition, can crooked this folded part (3), because flecition, a side that makes lower hem be bent collapses in the circular arc line arch of upper hem and does not rebound, and opposite side still remains unchanged, and makes this folded part (3) keep case of bending like this.When compression, the whole or corresponding folding pattern of compression section makes the counterpart that has only of folded part (3) compress as required.Also can only compress a side of folded part (3), make folded part (3) bending.Therefore, the utility model can arbitrarily compress and twist as required.So, advantage such as the utility model compared with prior art has and can not rebound, can arbitrarily fold after easy to use, folding and crooked, and result of use is good.

Embodiment:

Embodiment of the present utility model: the built-in loudspeaker of sound box bodies (1), middle control case (2) built-in speaker circuit board and relevant components and parts, its shell all can adopt plastics or metal material mold pressing to make.Can set up switch, electronic clock, broadcast receiver, volume knob functional devices as required on the middle control case (2).Between sound box bodies (1) and middle control case (2), be provided with telescopic folded part (3).Its power supply can adopt at middle control case (2) mode that battery case uses battery is set, and also can adopt the USB output socket that sets up standard to utilize the mode of computer USB power supply.

Folded part (3) can be made into circle or ellipse during making, and both sides keep being connected respectively with sound box bodies (1) and middle control case (2).When making folded part (3), telescopic folded part (3) is interconnected to folding pattern by upper hem (4) and lower hem (5) to be formed, and the cross sectional shape of its upper hem (4) is made as the circular arc line shape, the cross sectional shape of lower hem (5) is made as rectilinear form, and the cross sectional shape that makes upper hem (4) is that the arc length L1 of circular arc line is the straight length L2 of straight line greater than the cross sectional shape of lower hem (5); During making, the cross sectional shape that preferably with the cross sectional shape of upper hem (4) is the arc length L1 of circular arc line and lower hem (5) is that the ratio of the straight length L2 of straight line is controlled in the scope of L1: L2=1.15～1.30; The quantity that is interconnected to the folding track of the telescopic folded part (3) that folding pattern forms by upper hem (4) and lower hem (5) can control according to the length that will use, degree is big more, its road number is just many more, under the regular situation quantity of the folding pattern of folded part (2) is controlled in the scope in 3～20 roads to get final product; Because the motion of folded part (3) needs to contact with air, therefore can be placed on folding required pore (6) on sound box bodies (1) or middle control case (2) or the folded part (3) as required.Folded part (3) can adopt traditional material, or the plastic material with certain elasticity and plasticity is made, but, preferably adopt polypropylene plastics material (being the Polypropylene plastics, just usually said PP plastics) and polyethylene English material (the PE plastics that Polythylene or polythene are just usually said) to make the folded part on entire container 1 and the container body thereof (2).
