Abstract
The utility model relates to electroacoustics field, particularly a kind of 2.5 adjusting microinching magnetic speakers.Comprise magnetic conductor bowl, magnet steel, voice coil loudspeaker voice coil, bullet ripple, cone, frame, one end of voice coil loudspeaker voice coil and bullet wavelength-division are not placed in frame and are adhesively fixed with frame, magnet steel one end and magnetic conductor bowl are adhesively fixed, magnetic conductor bowl one end be placed in play ripple mesopore in be adhesively fixed, the magnet steel other end is placed in voice coil loudspeaker voice coil other end internal clearance and coordinates, cone respectively with lead magnetic conductor bowl and frame is adhesively fixed.Beneficial effect is: compared with common 2.5 cun of moving-coil speakers, and 2.5 adjusting microinching magnetic speakers designed by us have stronger low frequency performance, as being assemblied in television set or small-size sound box, effectively can improve the low frequency result of broadcast of Mini-type audio equipment unit; And this dynamic magnetic project organization has certain expansion, can be applicable to other specification loudspeaker unit.
Description
Technical field
The utility model relates to electroacoustics field, particularly a kind of 2.5 adjusting microinching magnetic speakers.
Background technology
The loudspeaker unit majority that electroacoustic series products in the market uses is coil-moving speaker, because dynamic magnetic structure loud speaker process costs is higher, be difficult to be applied in the speaker product of large-size unit, therefore only in the microminiaturized product such as high-end earphone of minority, have employed dynamic magnetic structure loud speaker in recent years.Compared with the coil-moving speaker of same dimensions, the source of sound that dynamic magnetic structure is embodied in more low-frequency range on the electroacoustic performance of loud speaker reproduces, low-frequency effect is stronger, if can by dynamic magnetic structure loudspeaker applications in the use scenes such as television set, small-size sound box, the low frequency audio visual effect that user can be allowed to enjoy more shake.
Summary of the invention
Technical problem to be solved in the utility model is: with 2.5 cun of loud speakers for specification, and a kind of supporting construction reliably of design makes loud speaker magnet steel hang, and drives cone sounding by the magnet steel of loud speaker, reaches the low frequency audio visual effect more shaken.In this scheme, voice coil loudspeaker voice coil adopts fixing design, and magnetic conductor bowl and magnet steel (neodymium iron boron material magnet steel) are inverted and are supported by playing ripple, bonding with cone bottom magnetic conductor bowl, finally drive cone to vibrate by magnetic conductor bowl and magnet steel.
The technical solution adopted in the utility model is: a kind of 2.5 adjusting microinching magnetic speakers, comprise magnetic conductor bowl, magnet steel, voice coil loudspeaker voice coil, bullet ripple, cone, frame, it is characterized in that: one end of described voice coil loudspeaker voice coil and bullet wavelength-division are not placed in frame and are adhesively fixed with frame, described magnet steel one end and magnetic conductor bowl are adhesively fixed, described magnetic conductor bowl one end be placed in play ripple mesopore in be adhesively fixed, the described magnet steel other end is placed in voice coil loudspeaker voice coil other end internal clearance and coordinates, described cone respectively with lead magnetic conductor bowl and frame is adhesively fixed.
The beneficial effects of the utility model are: compared with common 2.5 cun of moving-coil speakers, 2.5 adjusting microinching magnetic speakers designed by us have stronger low frequency performance, as being assemblied in television set or small-size sound box, the low frequency result of broadcast of Mini-type audio equipment unit effectively can be improved; And this dynamic magnetic project organization has certain expansion, can be applicable to other specification loudspeaker unit.
Accompanying drawing explanation
Fig. 1 is the utility model structure cutaway view;
Fig. 2 is frequency response performance chart of the present utility model.
Embodiment
As shown in Figure 1, a kind of 2.5 adjusting microinching magnetic speakers, comprise magnetic conductor bowl 1, magnet steel 2, voice coil loudspeaker voice coil 3, play ripple 4, cone 5, frame 6.
Be adhesively fixed median plane in magnet steel 2 one end and magnetic conductor bowl 1 formation magnetic circuit part, voice coil loudspeaker voice coil 3 and bullet ripple 4 are placed in frame 6 respectively, one end and frame 6 bottom surface of voice coil loudspeaker voice coil 3 are adhesively fixed, play ripple 4 and frame 6 one to enclose boss and rise and be adhesively fixed, magnetic conductor bowl 1 is inverted its one end carry out bonding through playing ripple 4 mesopore and support whole magnetic circuit part by bullet ripple 4, the other end of magnet steel 2 is placed in voice coil loudspeaker voice coil 3 other end internal clearance and coordinates, cone 5 and frame 6 frame mouth end are adhesively fixed, magnetic conductor bowl 1 above and in frame 6 median plane be adhesively fixed.During speaker operation, voice coil loudspeaker voice coil 3 maintains static, and magnetic circuit part vibration drives cone 5 vibration sounding.
As shown in Figure 2, this frequency response curve reads the sensitivity mean value of 100 ~ 4KHz frequency range, and its sensitivity is 71.6dB, compares the ventional loudspeakers of same dimensions, and it is more level and smooth on the low frequency curve of institute's reading frequency, and low frequency extension property is more outstanding.
