Embodiment

What the invention is intended to partly or entirely embodies in the following description, or acquistion in implementing process of the present invention.

Disclosed for audio frequency apparatus is gathered in the structural approach of rotatable magic cube inside, mainly be to be applied to rotatable magic cube type electronic product, be embodied in a kind of fixing and rotational structure, the following elaboration of carrying out the structural approach of a magic square audio amplifier.

Profile of the present invention is the magic square series products, and following is example (consulting Fig. 1) with three rank magic squares.The agent structure of the regular cube of magic square is divided into four parts, be respectively angle monomer 110, rib monomer 101, center monomer 102 and center spheroid 202, see also Fig. 2 and Fig. 3, center monomer 102 among Fig. 2 immobilizes with the relative position of center spheroid 202, and the relative position of each center monomer 102 is fixed.Center monomer 102 is enclosed within on the duct end 310 of center spheroid, can serve as that axle carries out the plane axial rotation with pipeline 401.Fig. 3 has shown in the three rank magic squares relative position schematic diagram of four array speakers 501 and segment angle monomer 110 and rib monomer 101, the cooperation cambered surface 810 of angle monomer 110 is attached to center spheroid 202 surfaces as shown in FIG., can slide on center spheroid 202 surfaces.

Wherein angle monomer 101 namely is positioned at the monomer on four angles of magic square; Rib monomer 101 namely is positioned on every limit of magic square appearance, the monomer that closes on angle monomer 110; Center monomer 102 namely on six appearance of magic square, is positioned at the monomer at face center; Center spheroid 202 is namely in magic square inside, in order to support peripheral ridge units 101, angle monomer 110 and center monomer 102.And the external structure of magic square, the i.e. profile of regular hexahedron have been constituted by angle monomer 110, rib monomer 101 and center monomer 102.The realization main points of this structure are based on center spheroid 202, and to be profile constitute according to the structure of interior round foreign side for angle monomer 110, rib monomer 101 and center spheroid 202.Arranging of they is as follows:

1) center monomer 102 and center spheroid 202

Center monomer 102 is enclosed within four duct end 310 outsides of center spheroid 202, and is constant with center spheroid 202 relative positions, distance, and namely when magic square is rotated, the relative position of center monomer 102 is fixed on six faces.But the rotatability based on magic square, for cooperating other angle monomers 110, rib monomer 101 is rotated, center monomer 102 needs and can axially rotate around pipeline 401 on duct end 310, so part is to be enclosed within duct end 310 by center monomer 102, and with 310 fixing can not disengagings of duct end (see also Fig. 4, as shown in the figure, center monomer 102 is fixed with the relative position of center spheroid 202).It is middle with pipeline 310 to adopt spring 301 to be compressed in center monomer 102 among the present invention, in order to increase the rotatability of center monomer 102.

And at the changeless advantage of relative position of center monomer and center spheroid, loud speaker, button and the coffret of audio amplifier can be located in the center monomer, electric wire is connected with circuit part in the spheroid of center by pipeline.Four array speakers 501 of present case, five namely are positioned at the center monomer 102 of six faces to key 201 and Mini USB coffret 410, all be to be fixed on the duct end 310, can not move (seeing also Fig. 5), they are separately fixed on the duct end 310 of center spheroid 202, the electric wire part is then smoothed out with the fingers line by the pipeline 401 at center and is guided in the center spheroid 202, and circuit board and battery part 710 can be fixed in the space of center spheroid 202.And the enclosure space of center spheroid 202 can form the back cavity of loud speaker 501, shown in Fig. 6 a, b, center monomer 102 and duct end 310 are fitted together difficult drop-off again when guaranteeing that center monomer 102 can rotate freely by spring 301 and some fixed structures.Permanent circuit part and battery are in the inner chamber of center spheroid, and the cooperation cambered surface 810 of monomer is attached to the surface of center spheroid 202, and the cooperation cambered surface 810 of all monomers can form the spheroid of a hollow, satisfies the acoustics requirement of loud speaker, reaches certain audio.

2) rib monomer 101 and angle monomer 110

Rib monomer 101 and angle monomer 110 are centered around center monomer 102 and center spheroid 202 outsides, form the profile of magic square.And rib monomer 101 and angle monomer 110 are constant with the relative distance of center spheroid 102, and relative position is variable.Each rib monomer 101 slides also at spherome surface respectively with angle monomer 110, and relative spheroid is rotated, between monomer and the monomer then by the outstanding cambered surface 810 engaged (cooperation cambered surface 810 shown in Figure 7 namely is the fixed structure of monomer) that cooperates on the monomer angle, it then is a hollow ball that surrounds the center spheroid that cooperation cambered surface 810 on the monomer angle combines, so can realize the rotation of any free angle of angle monomer 110 and rib monomer 101.And in this three rank magic square, the standing part of the cooperation cambered surface 810 of rib monomer angle monomer after engaged all concentrates on center monomer 102 places of each face of magic square in each rank, fixed structure by the center monomer place is snapped at center spheroid 202 outer surfaces with rib monomer 101 and angle monomer 110, makes it can not break away from spherome surface in rotary course.
