Abstract
The utility model discloses a horn for magic sound of desired frequencies or directional characteristics. The utility model is characterized in that both ends of a coil winding of the utility model are respectively provided with a positioning threaded rod which is provided with a pressure spring; the end of the positioning threaded rod is fixed to a large pronunciation plate or a small pronunciation plate; the outer margin and the back of the pronunciation plate is provided with an acoustic material layer; the horn is fixed to the bottom or the table board of a sound box by a support; coil winding wires are connected with an audio power supply by a plug. The utility model has the advantages of simple structure, light weight, easy adjustment of tone, long service life and low cost, which is a novel horn.
Description
The utility model relates to a kind of pickoff, particularly a kind of Horn for obtg. sound of desired frequency or directional characteristics.
Loudspeaker kind commercially available at present and that use is more, but its structure is basic identical, loudspeaker are provided with the magnet of a generation permanent-magnetic field outward, its magnetic field intensity is constant, and is provided with coil windings in the corresponding loudspeaker of magnet, and coil windings also produces a magnetic field after by tone currents, this magnetic field intensity changes with the tone currents size, because permanent-magnetic field and audio frequency magnetic field interaction, and through the frequency dividing circuit frequency division, and then promotion audio frequency sheet produces the vibration of different frequency and produces various sound equipments.There is following defective in the loudspeaker of this structure, and the one, complex structure, weight is big, lower tone, the price height, the 2nd, tonequality can't be adjusted, and the 3rd, easy broken string, useful life is short.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, in light weight, and tonequality can be adjusted, the Horn for obtg. sound of desired frequency or directional characteristics of long service life.
The purpose of this utility model realizes by following technical proposals:
Respectively establish a location screw rod at the coil windings two ends, screw rod one end is direct or affixed by magnetic conductor and coil windings end, the screw rod other end is affixed with big pronunciation sheet or little pronunciation sheet, and screw rod is provided with stage clip between pronunciation sheet and coil windings, and it is affixed that horn body passes through a support and audio amplifier bottom or table top.The coil windings lead passes through plug or directly links to each other with the audio frequency power supply, and the pronunciation sheet outer rim and the back side are provided with sound-absorbing material layer.
Said big pronunciation sheet is pieced together the planar sheet structure that embedding or stickup form mutually successively by five tablets, is that sheet, sound intermediate frequency pronunciation sheet, sound intermediate frequency are filtered sheet, low frequency pronunciation sheet frequently frequently in high frequency pronunciation sheet, the high audio filter of being with centre bore from inside to outside successively.
Little pronunciation sheet is a high frequency pronunciation sheet.
The utility model mainly is after utilizing the connection tone currents, under the effect of magnetic force that coil windings produces and stage clip elastic force, make pronunciation sheet vibration pronunciation, when being high frequency, vibration frequency have only close magnetic property good, do not possess the high frequency pronunciation sheet vibration pronunciation that elastomeric material is made, also at first the vibration of high frequency pronunciation sheet when vibration frequency is intermediate frequency, and by high audio filter disc conduction drive intermediate frequency pronunciation sheet vibration pronunciation, also at first the vibration of high audio sheet when the vibration pronouncing frequency is low frequency, by the high audio filter disc, sound intermediate frequency pronunciation sheet, the conduction of sound intermediate frequency filter disc, drive low frequency pronunciation sheet vibration pronunciation, and make low, in, high frequency pronunciation sheet all vibrates pronunciation.
From above-mentioned situation as can be known, the purpose of this utility model can realize, it need not produce the magnet of wanting permanent-magnetic field, volume is lighter, do not need frequency dividing circuit to avoid the broken string situation to take place, prolonged useful life, simplify the structure greatly, reduced cost, it is easier to adjust tonequality by the size of adjusting the pronunciation sheet simultaneously.To set up a speaker effect outward better for loudspeaker during actual the use.
Accompanying drawing and drawing are described as follows:
Fig. 1 is the whole diagrammatic sketch of the utility model;
Fig. 2 is the utility model configuration diagram;
Fig. 3 is big pronunciation chip architecture diagrammatic sketch.
The utility model is described in further detail in conjunction with the embodiments with reference to the accompanying drawings below, as shown in Figure 1, 2, respectively establish a location screw rod 1,8 at the two ends of coil groups 5, an end of positioning screw 1 and an end of coil windings 5 are affixed, and the other end passes little pronunciation sheet 2 centre bores and connects by fixed by nut.On the screw rod between coil windings and little pronunciation sheet, be provided with stage clip 3, stage clip intensity and coil windings power adapt, little pronunciation sheet is the high frequency pronunciation sheet that close magnetic, non-elastic material are made, and sound-absorbing material layer 4 is posted at the little pronunciation sheet edge and the back side thereof, and present embodiment is selected the rubber layer for use.Magnetic conductor 6 ends of the other end of coil windings and an end of positioning screw 8 are affixed, and the other end of screw rod 8 passes big pronunciation sheet 7 centre bores and connects by fixed by nut.
Be provided with stage clip 9 on the screw rod between the magnetic conductor of coil windings and big pronunciation sheet, for increasing the stability of big pronunciation sheet, stage clip can be designed to radial, and promptly port footpath is big, and port footpath is little, and the heavy caliber end places big pronunciation sheet end.Big pronunciation sheet edge posts sound-absorbing material layer 10 with the back, and present embodiment is selected the rubber layer for use, horn body by a support 11 with at the bottom of the audio amplifier or table top affixed, coil windings is passed through plug 12 and is linked to each other with the audio frequency power supply.As shown in Figure 3, said big pronunciation sheet 7 is pieced together the plane structure that embedding or stickup form successively by five tablets, from inside to outside for being with the high frequency pronunciation sheet A of centre bore, it is identical with little pronunciation sheet, high frequency pronunciation sheet is high audio filter frequency sheet D outward, high audio filter sheet frequently is outward intermediate frequency pronunciation sheet B, and intermediate frequency pronunciation sheet B filters sheet E frequently for sound intermediate frequency outward, and sound intermediate frequency filter sheet frequently is outward low frequency pronunciation sheet C.
Claims (3)
1, a kind of Horn for obtg. sound of desired frequency or directional characteristics, comprise coil windings, support, attaching plug, audio frequency sheet, it is characterized in that the coil windings two ends respectively establish one the location screw rod, screw rod one end is direct or affixed by magnetic conductor and coil windings end, the screw rod other end is affixed with big pronunciation sheet or little pronunciation sheet, screw rod between pronunciation sheet and coil windings is provided with stage clip, the pronunciation sheet outer rim and the back side are provided with sound-absorbing rubber layer, horn body is affixed by support and audio amplifier bottom or table top, and the coil windings lead directly or by plug links to each other with the audio frequency power supply.
