Technical field
The utility model is related to a kind of dual drive racetrack loudspeaker, belongs to loudspeaker techniques field.
Background technology
Vibrating type horn volume traditional at present is big, and very wide, and voice coil loudspeaker voice coil is circle.Generally for the width for meeting client
Narrow requirement can only meet client by reducing magnetic circuit system and reducing vibrational system, and this means acoustic pressure can substantially become
Small, power is subjected to weaken significantly.If power is slightly larger to easily cause bad burning machine；Though simultaneously flat board Microspeaker volume it is small and
It is thin, but flat board Microspeaker can not bear too significant power demand, can only be by handle generally for the power requirement for meeting client
FO, which is drawn high, to be reduced the amplitude of loudspeaker to meet the demand of client, but it is strong thus to produce speakers low frequencies sense, loudspeaker
The work of excess load, also can bring hidden danger to quality.And this means power is subjected to greatly reduce, FO can substantially be drawn high, and be made
The amplitude of loudspeaker reduces, and is so difficult to meet existing market.
Or existing market demand electro-acoustic product super-thin, or width is narrow, low frequency is good, and power is big, such as current liquid
Brilliant TV, portable type mini audio etc., good low frequency sense will be had by requiring, power requirement is 6W-12W, so traditional at present
The dynamic speaker width of formula is larger, and volume is big, and the problem of meeting thin client and FO low is, it is necessary to which to sacrifice vibrational system wide
Degree and magnetic circuit system, it means that voice coil loudspeaker voice coil diminishes, and magnetic circuit diminishes, but diaphragm oscillations area diminishes and is difficult to bear high-power, this
Sample easily causes the bad problem of burning machine；Current plate speaker bears that power is small, no centring disk is supported simultaneously, significantly
Loudspeaker easily produce linear distortion, draw high monomer FO to meet guest's power demand under the vibration of degree, cause speakers low frequencies
Sense is bad to cause inside loudspeakers temperature to raise, and quality hidden danger occur.

Brief description of the drawings
Fig. 1 shows the structural representation of dual drive racetrack loudspeaker in embodiment.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the present embodiment is a kind of dual drive racetrack loudspeaker, including plastic rubber bracket 1, be arranged on it is described
The PCB 2 at the back side of plastic rubber bracket 1, it is arranged on the positive vibrating diaphragm 3 of the plastic rubber bracket 1, is arranged on the plastic rubber bracket 1
On two magnetic circuit systems and two vibrational systems, wherein each magnetic circuit system includes secondary magnetic 4, pole piece 5, main magnetic 6 and magnetic cover 7,
Each vibrational system includes paper cap 8, voice coil loudspeaker voice coil 9 and locating branch slice 10, and magnetic cover 7 is arranged on the plastic rubber bracket 1, magnetic cover 7 it is interior
Portion is provided with main magnetic 6, and the top of main magnetic 6 is fixedly connected with pole piece 5, and the top of pole piece 5 is be bonded with secondary magnetic 4, magnetic cover 7 and main magnetic 6
Voice coil loudspeaker voice coil 9 is provided with gap between pole piece 5, the middle part of voice coil loudspeaker voice coil 9 is provided with locating branch slice 10, the middle part of voice coil loudspeaker voice coil 9 and positioning
The top of branch piece 10 is connected with vibrating diaphragm 3, and the top of voice coil loudspeaker voice coil 9 is be bonded with paper cap 8.
Preferably, the section of the voice coil loudspeaker voice coil 9 is racetrack, and the section of the magnetic cover 7 is racetrack.
Compared with prior art, the beneficial effects of the utility model are：The dual drive racetrack loudspeaker, by being arranged on
Vibrating diaphragm more than 3 increases a magnetic circuit system and vibrational system, make loudspeaker lengthened in the case where the width of vibrating diaphragm 3 is constant vibrating diaphragm 3 with
Increase vibration plane, double magnetic circuit allows whole system magnetic behavior to strengthen, improve acoustic pressure increase vibration intensity；Increase simultaneously has one to determine
Position branch piece 10 makes the Oscillation Amplitude distance of effective decay loudspeaker and effectively control vibration in the case where inputting big voltage uniform
Stability, so as to reach the effective stroke of reduction linear distortion and reduction loudspeaker, allow loudspeaker FO does is lower；Simultaneously will be former circular
Magnetic circuit is changed to racetrack magnetic circuit, in finite width space, increases magnetic and returns system, allows the core number of voice coil loudspeaker voice coil 9 to become the big and face of magnetic cover 7
Become big, so as to reach that the effect of voltage and increase acoustic pressure is born in increase；Power may be significantly lifting, and increase by a positioning
