Embodiment

Further specify embodiment below in conjunction with accompanying drawing.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4 Fig. 5, Fig. 6, Fig. 7, Fig. 8,1-housing protecgulum, 2-horn cover, 3-display window, 4-housing bonnet, 5-grid porous plate, 6-MP3 slot, 7-US socket and switch, the outlet of the right sound of 8-, 9-power source charges jack, 10-low pitch knothole, 11-high-pitched tone knothole, 12-signal are gone into socket, 13-steel wire, 14-charging socket, 15-MP3 socket, 16-window, 17-volume regulating block, 18-MP3 switch, the scalable repeating tube of 19-.As shown, housing is made up of protecgulum 1 and bonnet 4, and broadcast receiver and MP3 player socket are installed in the housing, and rechargeable battery, change-over circuit plate, blue tooth circuit plugboard, power amplifier plate, MP3 player and loudspeaker are installed; Also be provided with external power jack, USB jack, signal on the housing and go into jack, R channel output plughole.Innovative point of the present utility model is that the voice coil gap internal magnetic field intensity on the loudspeaker is made for 9000-12000 Gauss, the enlarged diameter of Ru-Fe-Mn magnet steel is to 24-32mm, the enlarged in thickness of magnet steel makes the sound reproduction of loudspeaker reach 80-110db to 6-8mm, and sound equipment integral body is made and can be put in the pocket.For sound equipment is not only given great volume and also tonequality good, the sound airflow path of shaking behind the loudspeaker is made through type, bonnet 4 is provided with grid porous plate 5 or mesh cover.In order to dwindle the volume of sound equipment, change-over circuit plate, blue tooth circuit plugboard and power amplifier plate are all being pasted inner walls installing, be provided with MP3 slot 6 at housing one side lower part, be used for installing the MP3 player.For repeating, the folding repeating tube 19 of equipped with telescopic on sound equipment, repeating tube 19 and the flexible suit of sound equipment housing.For sound equipment can be placed vertically, be provided with the steel wire 13 that can pull out propelling on bonnet 4 bottoms or the top of its housing, be used for supporting.Adopt the mark waterproof material to make to the pronunciation paper disc on the loudspeaker.Realized the purpose of the big volume of little sound equipment, changed people and big sound equipment had been had only the high-power traditional view that just can reach of big audio amplifier in the past.

The utility model mainly is in traditional sound box structure in the past, all there is air-flow to return the shake volume of tone chamber of hole, to strengthen acoustics volume, reach the effect of resonance of the voice, as want to do small size and be easy to carry, must get rid of this structure. but after getting rid of the tone chamber that shakes a following difficult problem can appear: because the front and back sound field can serious short circuit, the loudness of loudspeaker pronunciation can decline to a great extent, the volume because the front and back phase place is cancelled out each other on the contrary, and the tonequality volume can be had a strong impact on, particularly bass; Also to solve the effect that improves sound horn, reduce the power of power amplifier again, and the volume of the electric weight of electricity consumption and sound equipment. solve above these two difficult problems, specific embodiments is one, little for reaching volume, can stop the phase place of pronunciation behind the part loudspeaker the offseting of field phase of ditto pronouncing again, the volume of sound enclosure is done little as far as possible, diameter with loudspeaker is the size of casing rectangular planes, with the height of loudspeaker gauge as casing, with the volume of power-supply battery as casing inside dimension length, the outside dimension of casing is that iron sheet or plastics are made and decided according to material therefor, guard on the casing front panel horn disk face shield, make canopy lattice porous plate on the loudspeaker back shroud face or use the mesh cover, make the air-flow of loudspeaker unimpeded, make sound wave play maximum effect at space reflection. through practical application, prove effectively, the counteracting that has not only stoped a part of phase place is the sound field short circuit, and sound wave around the reinforced effects of space reflection also strengthen greatly. not only reduced the volume of casing through above this set, also improved certain sound equipment efficient simultaneously; Because the loudspeaker air-flow is straight-through shape, do not have the influence of the tone chamber's muddiness of shaking, make tonequality become pure more pleasing to the ear clearly. in order to reduce volume, take the change-over circuit plate, blue tooth circuit plugboard and power amplifier plate are pasting inner walls and are installing, be provided with MP3 or MP4 or MP5 slot or RF radio reception plate at housing one side lower part. two, in order to improve the pronunciation effect, loudspeaker voice coil gap internal magnetic field intensity is made 9000-12000 Gauss, the magnet steel of loudspeaker is adopted the Ru-Fe-Mn magnet steel, its diameter is 24-32mm, the thickness of magnet steel is 6-8mm, arrive 1-3 greatly doubly than traditional loudspeaker magnetic intensity, make the loudspeaker sound reproduction reach 80-110db, pronunciation paper disc on the loudspeaker adopts the mark waterproof material to make. is put in the pocket in order to make sound equipment, then sound equipment is made cigarette case volume of a size. and three, this sound equipment is as occasion use in the open air, because outer sound field conditioned reflex is poor, then need install the repeating cover additional, the repeating cover adopts the plastic telescopic pipe structure, telescopic folding is socketed on the sound equipment housing flexibly, when being put in the pocket at ordinary times, the repeating cover is folded up, and the sound equipment body is placed in the repeating cover; Repeating cover launches the resonant tank that the back becomes casing, and acoustics is significantly improved. and four, can place vertically in order to make sound equipment, be provided with the steel wire that can pull out propelling in sound equipment housing bonnet bottom or top, the strutting piece when placing sound equipment vertically.

The little function of the utility model volume is many, and is in light weight, gives great volume, power-saving, practical, and functional integration is high to be used extensively; In daily use, be convenient for carrying, as the wireless performance Karaoke of middle-size and small-size occasion, NP3 or MP4 music, the morning exercises of physical culture music, general meeting-place amplifies, the use such as multimedia computer notebook sound equipment occasion that amplifies of teaching of teacher classroom.
