Embodiment
In graphic, loudspeaker assembly 10 comprises that one has the case 11 of a header board 12.This case can comprise the shell of loud speaker, its can merge to the vehicular meter panel the inside or above.
What be associated with plate 12 is a circulator 13, and it is mounted to rotation in one or more path of the sound wave that is produced by a loudspeaker vibrating diaphragm 15 (seeing arrow 14).The circuit that is used to drive this vibrating membrane is shown in 16, and actuating mechanism is shown in 17.
One rotary driver (for example motor 20) is positioned between vibrating membrane and the circulator to rotate this circulator.Drive enclosure 20a is carried by strutting piece 21 usually, and this strutting piece 21 is the form of retainer ring 21a, and its installation by plate 12 is carried along periphery at 22 places with annular section 12a.The outside annular extension 15a of vibrating membrane 15 also can be carried by 12a.Annular section 12a also carry one by this circulator along the upright installing ring 24 of periphery around (promptly circulator wheel rim 13a outer edge).
Between each alternate arm 13b of this circulator, be formed with opening 26, so that produced and guide the sound wave that passes substantially across the circulator in one or more path 14 of these ripples to pass through by vibrating membrane 15.As shown in Figure 2, arm 13b is preferable has radially a width that outwards increases.For safety, narrow tie rod 29 outside circulator rotating shaft 13d at each these arm in succession of extension 13c place interconnection of the narrower width of arm in succession.Other sees non-rotating arm 133, and it is generally along radially protrusion and also formation opening 26a outside anchor hub 134.The bearing 135 and cover 137 of anchor hub 134 carrying motor reels 136 overlap 137 these circulators of carrying.Arm 133 provides stationary grizzly 133a.
Fig. 1 display driver axle 136 upwards stretches in the circulator cover.Annular bearing 135 is positioned between rotatable rotary device hub sleeve 137 and the hub 134 by strutting piece 21 carryings.
In operation, driver is preferable makes and can rotate this circulator to the speed that the described sound wave that passes the described opening between these arms carries out the sound equipment modulation by copped wave with one.This kind modulation is enhanced by described variable-width circulator arm is set.It shall yet further be noted that vibrating membrane 15 (being preferably a bass horn) generally caves in towards circulator.Driver generally is positioned at the center of the axis that is defined by circulator, and supports the circulator rotation, and driver is between circulator and vibrating membrane.
Another feature of the present invention provides the LED of one or more non-rotating structural bearings by the circulator device.In Fig. 5-7, LED 210 is by anchor hub 134 carryings, and the narrower extension 13c in inside that rotates hub 211 and arm 13b with the center aligns.These LED can protrude towards the direction away from this circulator, so that the bright involving vibrations film 15 of its illumination is in the interior internal structure that can see by the opening between each turning arm 13b, the one effect is to produce the effect of a similar reverberation stroboscopic when turning arm 13b intersection is crossed arm 133, and receives from the light of vibrating membrane reflection.Controller 100 comprises that one is used to increase or reduce the hand controller 100a of illuminance; And these LED can produce the light of different colours to strengthen visual effect.All arms all can be high reflection (as by applying chrome plating), with the indirect inside reverberation of reflection by these arm copped waves.
Can for example, hub sleeve 137 pull down circulator 13 on motor driven shaft 136 by being separated; Can on axle 136, use one and substitute circulator, to produce different visions and auditory effect.Grid 133a is also detachable, replaces to use a grid with different arm designs.Therefore, can provide the various combination that can realize different-effect like a cork, for example:
Grid A+ circulator C
Grid A+ circulator D
Grid B+ circulator C
Grid B+ circulator D, or the like.
Circulator is changed can face automobile instrument panel by automobile passenger, pull out and change circulator as required easily realizes.
