When the elastic section 20 laps, in the axial direction, the expansion body 1 is compressed in the axial direction.
During the conversion of the expansion body 1 in the compressive state and the expanding state, the volume of the inner space changes, so the air inside has to be adjusted for pressure balance inside and outside. This embodiment is applied with a lockable air valve 2. When the expansion body 1 is conversed between the compressive and expanding state, the air valve 2 is opened to allow the air inlet and outlet.
It's clear that with the expansion body 1 of the expansion section and the elastic section, a sound box with a compressible volume is provided. The sound box with enough volume can be compressed. And the elastic section 20 is made of flexible material to connect the expansion section one by one. So that in the expanding state, the size of the resonance space inside the expansion body is stable when the speaker 30 works, and it provides with well anti-deformation capacity. The sound box has well portable performance,
Refer to the fig.3 and fig.4 of the first embodiment applied in the portable equipment 40. the external diameters of the expansion sections of the expansion body 1 from the top expansion section I I to the bottom expansion section 13 are gradually decreased in the axial direction, making the expansion body 1 with a large end and a small end. In the compressive state, start from the small end, each expansion section is sleeved in its later one, making the expansion body 1 with well strength in the compressive state.

The expansion body I of this embodiment has a small middle and two large ends in the axial direction. The expansion section is situated in the middle in the axial direction. That is to say, the external diameter of the expansion section 12 is smallest. Other expansion sections are gradually enlarged toward the two ends in the axial direction. In the two large ends of the expansion body 1, the two top expansion bodies 11 are separately disposed with a speaker 30 and a passive diaphragm 50 of resonance with the speaker 30 on the bottom surface.
It is clear that the expansion body 1 of this embodiment is of symmetry. When in the compressive state in the fig.8, the top expansion section 11 and the bottom expansion section 13 are formed to be a container to contain the other expansion sections and elastic sections with small size. In the other hand, the length of the speaker 30 is larger in the axial direction.

A semitransparent material with a gentle glow is better. The expansion body 1 can be served as a night light of luminescence with lighting function.
The forth embodiment:
Refer to the fig.10 and fig.l 1 of the forth embodiment of the present invention.
Similar to the third embodiment, the expansion body 1 is shaped with a small middle and two large ends in the axial direction. The expansion section 12 is disposed in the middle in the axial direction with the smallest external diameter. The external diameters of other expansion sections are gradually increased toward the two ends of the expansion body 1 in the axial direction, in the two large ends of the expansion body 1, the two top expansion bodies 11 are separately disposed with a speaker 30 and a passive diaphragm 50 of resonance with the speaker 30 on the bottom surface. Similarly, the expansion body 1 of this embodiment is of symmetry. When in the compressive state, the top expansion section 11 and the bottom expansion section 13 are formed to be a container to contain the other expansion sections and elastic sections with small size.
In this embodiment, the expansion body 1 is disposed with an illumination source 60, which is placed in a special position. A light window 51 of illumination is disposed on the passive diaphragm 50. When the bottom expansion section 13 and the middle expansion section 12 are relatively compressed, light is transmitted through the light window 51 without stopped by the inner wall of the expansion body 1. The expansion body 1 is made of a diffused transmission material, so this embodiment can be served as an appliance with double illumination functions. When the expansion body 1 is situated in the expanding state, light of the illumination source 60 casts inside the expansion body 1 and diffused out to make the expansion body a night light of luminescence. When the expansion body 1 is situated in the compressive state, light of the illumination source 60 casts without adjust, making the expansion body 1 a spotlighting.
