Description
Technical field
The utility model relates to a kind of thin speaker.
Background technology
Market conventional thin loud speaker, because limitation in height, with respect to conventional loudspeakers, the acoustics performance has following shortcoming:
1. the stroke of loud speaker (peak swing X
Max) little, be difficult to the following bass of effective radiation 200Hz.
2. the degree of depth of the diaphragm of loudspeaker little (or saying that the bus slope is little), " geometry intensity " is low, has in the medium-high frequency section and obviously cuts apart vibration, and the frequency response curve peak valley is more, is difficult to the sound of effective radiation medium-high frequency section; Though and the plate diaphragm loud speaker passes through to use the high material of rigidity, suppress to cut apart vibration, effectively the above high pitch of radiation 15kHz.
3. the fit dimension between each parts of loud speaker is less than normal, is difficult to improve the production operability and produces the line qualification rate.Carry out many-sided innovation transformation by organization plan, above shortcoming can be dropped to bottom line thin speaker (especially small-bore thin speaker).
The utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides the thin speaker that a kind of low frequency performance is good, the medium-high frequency response is smooth, the production operability is good.
To achieve these goals, the utility model adopts following technical scheme: a kind of thin speaker, comprise basin frame, cone, voice coil loudspeaker voice coil and magnetic circuit system, it is characterized in that: described magnetic circuit system comprises U iron, magnet, magnetic conductive board, and is in the high saturation and magnetic intensity in the bigger magnetic slit of this three, low viscous magnetic liquid; The top of described voice coil loudspeaker voice coil is connected with cone, its lower end stretch between U iron and the magnetic conductive board the space in.
Described cone be shaped as cambered outwards taper, cone is provided with the ring that outwards arches upward, the centre of cone is provided with incorporate dust cap.
The dust cap of described cone is for caving inward.
The radius of curvature on described cone ring top is littler than the radius of curvature of bottom.
The ring inboard of described cone is thicker than the outside.
Described cone is provided with radial reinforcement.
Described U iron top edge is big chamfering, and the magnetic conductive board middle part is provided with groove.
Described U iron inwall is provided with deep-slotted chip breaker.
The utility model compared with prior art has following beneficial effect:
1, saved the bullet ripple, under the situation of equal height, provide more strokes (peak swing X for vibrational system (cone, voice coil loudspeaker voice coil)
Max), promptly the low frequency performance of loud speaker has obtained optimization, though lose the centering effect that plays ripple, but in magnetic circuit system, suitably strengthened the magnetic slit, in the magnetic slit, inject high saturation and magnetic intensity, low viscous magnetic liquid, assisted the voice coil loudspeaker voice coil location, make loud speaker can not have the risk of rubbing circle.
2, process big chamfering in U iron top edge, magnetic conductive board middle part machined grooves has been avoided the cone (comprising dust cap) of large amplitude, allows bigger stroke (peak swing X
Max).
3, cone ring top is higher, sees that from section ring is non-semicircle, allows bigger stroke (peak swing X
Max).
4, U iron inwall is processed with deep-slotted chip breaker, has improved magnet accumulating cap, has overcome the deficiency that has reduced magnetic flux density because of the magnetic gap that has increased magnetic circuit system; And inject magnetic liquid in the magnetic gap and can also reduce leakage field, further improve the magnetic induction in the magnetic gap.Magnetic liquid can also improve loud speaker machinery resistance R
MS, and then reduce Q
MSAnd Q
TS, also can improve the radiating effect of magnetic circuit.
5, the inverted cone structure of employing and traditional cone, the whole height of cone obviously obtain compression; The ring inboard is thicker than the outside, has effectively alleviated because highly limited, and the cone slope is less than normal, and causes the peak valley problem of frequency response curve in the medium-high frequency section, even loud speaker has been obtained on the medium-high frequency section and responded smooth effect; Cone is provided with radial reinforcement, has improved the piston vibration frequency range, has prevented to cut apart in lower frequency range the problem of vibration.

Embodiment
As Figure 1-3, a kind of thin speaker, comprise basin frame 1, cone 9, voice coil loudspeaker voice coil 3 and magnetic circuit system, described magnetic circuit system comprises U iron 6, magnet 5, magnetic conductive board 4, and the high saturation and magnetic intensity that charges in the bigger magnetic slit of this three, low viscous magnetic liquid; Described cone 9 be shaped as cambered outwards taper, cone 9 is provided with the ring 2 that outwards arches upward, the centre of cone 9 is provided with incorporate dust cap 10, the dust cap 10 of described cone 9 also is provided with radial reinforcement 16 for caving inward on the cone 9; The top of described voice coil loudspeaker voice coil 3 is connected with cone 9, its lower end stretch between U iron 6 and the magnetic conductive board 11 the space in.
Described U iron 6 top edge are made as big chamfering 13, and U iron 6 inwalls also offer deep-slotted chip breaker 12, and magnetic conductive board 4 middle parts are provided with groove 11.
The radius of curvature on described ring 2 tops is littler than the radius of curvature of bottom, promptly is seen as the higher non-semicircle in middle part from section, and is made into the inboard 14 of ring 2 thicker than the outside 15.
In order to solve the fit dimension problem less than normal between each parts of loud speaker, improve the production operability and produce the line qualification rate, the technology of making present embodiment is as follows:
The first step as shown in Figure 4, cooperates special tool 17 with basin frame 1 and voice coil loudspeaker voice coil 3, the lead of voice coil loudspeaker voice coil 3 is stuck in the groove of the lead-in wire 7 on tool 17 ad-hoc locations, and with terminal 8 welding, for cooperating this special construction, with terminal 8 position optimizations to basin frame 1 bottom.
