Abstract
The utility model provides a moving coil type loudspeaker which adopts a large voice coil. The utility model is characterized in that the edge of a paper cone in a loudspeaker is provided with a large voice coil and is arranged in a magnetic circuit which is composed of a magnetic-conductive frame plate, a magnet, a T-shaped magnetic-conductive hollow column. When an audio current passes through the large voice coil, magnetic fields interact and drive the paper cone to vibrate. Because of enlarging the diameter of the voice coil, the work efficiency of the loudspeaker is enhanced effectively. The T-shaped magnetic-conductive hollow column can make the air circulate and not influence the paper cone to sound.
Description
The utility model relates to that a kind of variation tone currents converts mechanical oscillation to and the loud speaker of sounding is particularly a kind of simple in structure, conversion efficiency height, the big voice coil loudspeaker voice coil coil-moving speaker that audio distortions is little.Being suitable for that various tone currentss are converted to mechanical oscillation promotion air sounds.
Existing coil-moving speaker is made up of voice coil loudspeaker voice coil, cone, magnet, soft iron, the magnetic field interaction that magnetic field that tone currents produces during by voice coil loudspeaker voice coil and magnet, soft iron form, and drive the cone vibration sounding.The voice coil loudspeaker voice coil of existing loud speaker is installed in the cone center, and the effective sounding area of the size of voice coil diameter and cone is inversely proportional to, and directly influences sounding effect.Therefore strengthening voice coil diameter is subjected to certain placing restrictions on.The magnetic flux that produces when less voice coil loudspeaker voice coil is worked is low, and heat-sinking capability is poor, and is few with the contact-making surface of cone, reduced the Oscillation Amplitude of cone.Therefore to improving the conversion efficiency of loud speaker, reduce distortion, increase power and all can't effectively be implemented.
Task of the present utility model provides a kind of coil-moving speaker that adopts big voice coil loudspeaker voice coil, and it can improve conversion efficiency effectively, reduces audio distortions, and has increased the power of loud speaker.
Task of the present utility model is finished as follows: the cone outer ring in the loud speaker is bonded in basin frame front portion.The cone edge has ring, and the ring inner ring is installed big voice coil loudspeaker voice coil.T shape magnetic conduction open tubular column, annular magnet, magnetic conduction deckle board constitute the soft iron circuit system and are installed in basin frame middle part.Big voice coil loudspeaker voice coil is in the soft iron circuit, and the connected set at cone center and elastic support center join.Elastic support is installed in basin frame afterbody.When magnetic field that tone currents produces during by big voice coil loudspeaker voice coil and the magnetic field interaction in the soft iron circuit, and drive cone and do mechanical oscillation.Hollow T shape conducting magnetic column ventilates and does not influence the cone sounding.Increase the voice coil loudspeaker voice coil magnetic flux height of diameter, heat-sinking capability is strong, and is many with the contact-making surface of cone, improved the operating efficiency of loud speaker significantly.When the exemplary construction that will describe in detail below adopting, the coil-moving speaker of voice coil loudspeaker voice coil is simple in structure greatly, and the conversion efficiency height has certain economic benefit.
Below with reference to accompanying drawing the utility model is described in further detail.
Accompanying drawing is a kind of concrete structure figure of the present utility model.
With reference to accompanying drawing: the outer ring of cone (1) is bonded on the anterior edge of basin frame (7), and the cone edge has ring (2).Install by copper cash (12) and be wound on big voice coil loudspeaker voice coil (3) on the skeleton (11) at ring inner ring place, and the cross section of skeleton is identical with the cross sectional shape at ring inner ring place.Skeleton (11) surface has several holes (10), ventilates and reduces voice coil loudspeaker voice coil weight.Middle the heart channel of Hang-Shaoyin connected set (8) of cone (1) is connected with the center of elastic support (9), and elastic support is the crimp ring shape, has certain elasticity, is installed in the afterbody of basin frame (7).The magnetic conduction deckle board (4) of soft iron magnetic material, the annular magnet (5) of hollow conducting magnetic column of T shape (6) and hard iron magnetic material constitutes the soft iron circuit system, is installed in the middle part of basin frame (7).Copper coil (12) on the big voice coil loudspeaker voice coil (3) is in the soft iron circuit, and the magnetic gap of magnetic circuit is 0.5mm to 2.5mm.When tone currents during by the copper coil (12) on the big voice coil loudspeaker voice coil (3) loud speaker start working.The voice coil loudspeaker voice coil (3) that increases diameter is more with the contact-making surface of cone (1), and heat-sinking capability is strengthened, and magnetic flux improves, and the interaction force between magnetic field is also big, and makes cone (1) amplitude broadening, has improved the conversion efficiency of loud speaker effectively, has reduced audio distortions.Because to be in cone (1) back is hollow T shape conducting magnetic column (6), air can be circulated and does not influence the cone sounding.
