Embodiment
Below in conjunction with accompanying drawing, summary of the invention is described further:
Shown in Fig. 1, can generate the audio frequency apparatus of surround sound, comprise hollow housing 1, the top of described hollow housing 1 is provided with the poroid through hole 2 of waist, on the antetheca of described hollow housing 1, have more than one manhole 3, on the poroid through hole 2 of described waist, be coated with the top membrane 4 of sheet, and on described each manhole 3, be coated with the equipment 5 for pronouncing.The outside of the top membrane 4 of described sheet is the poroid outside projection 6 of waist, the outer wall of the poroid outside projection 6 of described waist is connected with the inwall of the poroid through hole 2 of waist, the inwall of the poroid outside projection 6 of described waist is connected with the bottom of the poroid arch projection 7 of waist, the inwall of the poroid arch projection 7 of described waist is connected with the outer wall of the poroid plate 8 of waist, and the joint portion that the inwall of the poroid arch projection 7 of waist is connected with the outer wall of the poroid plate 8 of waist is groove shape structure 9.The described equipment 5 for pronouncing comprises the electromagnet 21 of bottom for column, the top of described electromagnet 21 is connected with the bottom of the cup-shaped pallet 10 of metal material, on outer wall around described cup-shaped pallet 10, evenly offer plural perforate 11, on the outer wall of described cup-shaped pallet 10, be provided with two metal electrodes 12, rod member 13 inserts in electromagnet 21 through the inside of cup-shaped pallet 10, the portion of external that described rod member 13 inserts electromagnet 21 is wound with wire coil 14, described wire coil 14 is connected with two metal electrodes 12 respectively by two metal lead wires 22, the top of rod member 13 is connected with the bottom of columned the first flexible sheet 15, the bottom inward flange of the round table-like hood-like body 16 of the outer wall of the first flexible sheet 15 is connected, the outer wall of described hood-like body 16 is connected with the inwall of the first annulus arch 17 of elastomeric material, the outer wall of the first annulus arch 17 is connected with the inwall of the first torus 18 of plastic material, the outer wall of the first torus 18 is connected with the inwall of the second annulus arch 19 of elastomeric material, the outer wall of the second annulus arch 19 of elastomeric material is connected with the 3rd annulus arch 20 of elastomeric material, the top of described cup-shaped pallet 10 is connected with the bottom of the first annulus arch 17.
