Abstract
The utility model discloses a loudspeaker, which comprises a driver, a paper cone, a basin frame and additional parts thereof, and the driver is arranged at the front end of the paper cone or the paper cone is made into a plane shape. The utility model has the advantages of favorable tone quality effect, display of basetone, small size and long service life.
Description
The utility model relates to a kind of electroacoustic apparatus, especially loud speaker---coil-moving speaker.
Conventional coil-moving speaker, main structure is made up of driver (exciter), vibrating membrane (common name carton), basin frame and annex thereof.Driver is the heart of loud speaker, and it is made of front plate, rear plate (base plate), conducting magnetic column (common and rear plate is an one), magnet and voice coil loudspeaker voice coil.And driver all is mounted in the back of cone cone, promptly all in the bottom.
Because conventional cone work, be to be subjected to voice coil loudspeaker voice coil in the driver under the effect in magnetic field, to promote whole cone by the cone cone base to work, i.e. cone work by after drive forwards.Be not difficult to find out in the course of the work at this, the status that has the initiative, the cone base position of cone, and near being to be in passive state near the cone mouth.This work by the cone part drives whole cone, and be obviously unfavorable to the emission of sound, especially then more unfavorable to bass.Because promptly near near the cone the driver, the acoustic pressure that is produced is better than near the acoustic pressure the cone horn mouth in the bottom, promptly the acoustic pressure in same cone is just uneven.The crowd knows: the bass overwhelming majority is near the cone front end emission, and needs enough power to drive herein again.Yet the position but is the weakest unable herein, so just seriously influences the performance of bass.
Because the cone of conventional loud speaker is cone-shaped, does not outwards launch sound on same plane so sound source with regard to outwardness, the sound wave emission can not guarantee consistency in time like this, and life period is poor, thereby produces phase distortion.
Because the voice coil loudspeaker voice coil in the conventional loudspeaker drive is concentrated below the cone cone, diameter is very little, and not only radiating condition is bad for this, is often burnt, and influence loud speaker useful life, and power can not improve a lot fundamentally.
Because the structure of conventional loud speaker determines, the back that its driver must be installed in the cone cone is the bottom, so the depth size of loud speaker is the thickness of itself is that big reduction impossible fundamentally be arranged, and causes the audio amplifier volume excessive, is unfavorable for making relevant electroacoustic equipment.
Because the structure of conventional speaker determines that circle, the several simple kinds of ellipse are only arranged at present, this does not satisfy the requirement of the needs of growing electroacoustic equipment different levels and people's different aesthetic standards far away.
The utility model purpose is to avoid and overcome the deficiency of above-mentioned conventional coil-moving speaker, and provides one to be that to have an acoustic frequency response good, and tonequality is true to nature, especially to bass, mega bass, efficient height, the life-span is long, volume is little, style is many loud speaker.
The utility model purpose is achieved in that loud speaker comprises driver, vibrating membrane (cone), basin frame and annex thereof, change the drive location of traditional coil-moving speaker: it is the bottom that the driver routine is placed the back of cone cone, and change to cone front end---near coming installation of driver near the cone mouth, the center of driver is hollow shape.That is to say voice coil loudspeaker voice coil in the driver near the cone mouth, but be not on the cone limit, but back on the limit is strengthened the cone front-end driven is reached the purpose of giving full play to bass.
Shape for cone, also can or claim horn-like trend plane (as arc, pateriform, corrugated or the like) or the plane of changing into by traditional cone, so that being in same plane, sound source outwards pronounces, can reach and overcome phase distortion, can reach tonequality again responds, be beneficial to the voice coil loudspeaker voice coil heat radiation, make its life-span long, the purpose that volume is little.
Fig. 1, Fig. 2, Fig. 3 are three example structure sketches of this loud speaker.
Being the further technical characterictic of this loud speaker of statement, is example with the circular loudspeakers, and in order to say something, the cone among the figure all is that the cone with the plane is an example; In order to simplify, in each figure, do not draw in conventional loadspeaker structure intrinsic circle " centre of location is propped up sheet ", and the utility model props up sheet to the centre of location, be to have taked dispensable way: look speaker operation on which kind of audio frequency, the structure of itself only satisfies the actual conditions of certain special requirement and decides.
Referring to Fig. 1, loud speaker is made of basin frame 1, ripple line limit 2, cone 6 and the driver that links to each other with cone 6, the driver center is hollow shape, is that L shaped annulus magnetic conduction iron 3, voice coil loudspeaker voice coil 4, magnet 5 are formed by section, and the taper dotted line is the schematic diagram that cone adopts horn-like shape among the figure.
Referring to Fig. 2, it is spill annulus magnetic conduction iron 7 that magnetic conduction iron is made section, and voice coil loudspeaker voice coil is two groups of voice coil loudspeaker voice coils 8,9.
Referring to Fig. 3, in same concentric circles, be provided with driver 2--3 that work alone separately and at grade, as driver 10,11,12, the cone 2--3 that adapts therewith,, suitable equally to horn-like cone as cone 13,14,15.For taper cone peace facial tissue basin, hollow annular cone can be made in its center, as cone 14,15.
The utility model has changed the drive location in traditional coil-moving speaker, and is placed in the suitable position of front end of cone, has changed the cone shape, therefore transforms, and has then produced following outstanding good effect:
1, as can be seen from Figure 1, sound source is outwards to launch with plane form, has therefore overcome phase distortion.
2, be positioned on the appropriate location of cone front end because of driver, thereby the passive situation that routine is worked herein become initiatively, acoustic pressure that this is not only therefore further balanced, and the more important thing is that herein it is powerful and strong that cone works together, this performance to bass, mega bass plays crucial effects, and this is that conventional loud speaker is incomparable.
3, as shown in Figure 3, the utility model can be installed in same concentric circles and not disturb mutually, the 2--3 that works alone a separately driver is holistic, and sound source can guarantee that 2 drivers of the different audio frequency of synchronized transmissions are one or 3 combination loudspeakers that driver is an one at grade, this can't but be the breakthrough of a germplasm on the development history of conventional coil-moving speaker.This combination loudspeaker, it can not only avoid phase distortion, the performance of favourable bass, mega bass, and the more important thing is and strengthened telepresenc, make sound more true to nature.
4, since present technique to the change structurally of conventional loud speaker, it not only can reduce 40--60% than conventional loud speaker thickness (under identical bore, identical power conditions), and improved widely the radiating condition of voice coil loudspeaker voice coil thereby the useful life of having improved loud speaker.
5, as shown in Figure 2, on the basis that does not increase material, under the situation that original size remains unchanged substantially, only with the L type annulus magnetic conduction iron among Fig. 1, become Fig. 2 drop centre type annulus magnetic conduction iron, then can increase by one group of voice coil loudspeaker voice coil again, this thickness that not only further reduces loud speaker has been created condition, and the more important thing is loud speaker further is provided by the more high-power utmost point advantageous conditions that also provides.
6, the utility model can be by the needs of actual electrical acoustic equipment different levels and the requirement of the different aesthetic standards of people, except that the circle of routine, oval-shaped loud speaker, also can do triangularity, square, rectangle, polygonal loud speaker.
