Abstract
The invention discloses a four-drive mega bass automobile loudspeaker. The four-drive mega bass automobile loudspeaker comprises a pre-amplification circuit, an IC control board, four power amplification circuits and a loudspeaker body, wherein the pre-amplification circuit, the IC control board, the four power amplification circuits and the loudspeaker body are connected in sequence. The four power amplification circuits are connected to the IC control board. Four drive coils are arranged in the loudspeaker body. Each power amplification circuit is connected with one drive coil in a corresponding mode. When an audio current is input through the power amplification circuits, the four drive coils generate equal force in the same direction in a magnetic field and move vertically in a reciprocating mode along with change of electric signals, and then the loudspeaker body is driven to motivate air to vibrate so that a sound can be made. According to the four-drive mega bass automobile loudspeaker, the four power amplification circuits are used for driving the four drive coils so that a sound can be made, and the four drive coils generate equal force in the same direction in the magnetic field and move vertically in the reciprocating mode along with change of electric signals; compared with a loudspeaker body with only one drive coil, the loudspeaker body of the four-drive mega bass automobile loudspeaker can generate push-pull force which is four times as large as the push-pull force generated by the loudspeaker body with only one drive coil in the same magnetic field, in this way, the power is increased, the sound pressure is increased, the dynamic response speed is high, and the low frequency recurrence effect is remarkable.
Description
Technical field
The present invention relates to a kind of loud speaker, particularly a kind of powerful mega bass auto loud hailer that adopts a plurality of drive coils.
Background technology
Coil-moving speaker is a kind of loud speaker being most widely used now, existing traditional coil-moving speaker, generally comprise magnetism loop feature and oscillating component, because existing traditional coil-moving speaker is structurally by hanging on single or two voice coil loudspeaker voice coils in the magnetic field in magnetism loop, therefore,, when this voice coil loudspeaker voice coil passes to the tone currents of being exported by power amplifier, voice coil loudspeaker voice coil will be subject to the effect in magnetic field, place and produces motion, voice coil loudspeaker voice coil promotes oscillating plate and drives air to produce vibration, thereby sounds.
Due to the size of acoustic pressure and the vibration area of speaker diaphragm of coil-moving speaker, the stroke of motion of voice coil loudspeaker voice coil, becomes positive correlation with the power bearing, and therefore traditional mega bass loud speaker overall dimension is large and high; Be not suitable for using in little space, especially automobile-used.For mega bass loud speaker can be arranged in kart, use, just with traditional mega bass loudspeaker design thinking, by compression volume and power, achieve the goal, but effect is very limited; Main manifestations is that the little low-frequency effect of acoustic pressure is poor, is difficult to be accepted by most consumers on market; While particularly needing to have good mega bass effect, the volume of coil-moving speaker is generally relatively large, can not meet ultra-thin airtight small space instructions for use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides that a kind of power is large, small volume, mega bass auto loud hailer that low-frequency effect is good.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of 4 wheel driven moves mega bass auto loud hailer, comprise the pre-amplification circuit, IC control board, power amplifier and the loudspeaker that connect successively, on described IC control board, be connected with four road power amplifiers, in described loudspeaker, be provided with four drive coils, a drive coil of the corresponding connection of every road power amplifier, when from power amplifier input tone currents, four drive coils produce equal power in the same way and pump with the variation of the signal of telecommunication in magnetic field, drive loudspeaker to excite air vibration and produce sound.
In above-mentioned mega bass auto loud hailer, described IC control board is CD4558 chip.
In above-mentioned mega bass auto loud hailer, in described loudspeaker, be provided with magnetic conduction subassembly, described magnetic conduction subassembly top is provided with basin frame, on basin frame, be provided with vibration ring, on vibration ring, be bonded with oscillating plate, described basin frame middle part is provided with through hole, through hole is provided with voice coil loudspeaker voice coil, voice coil loudspeaker voice coil is arranged in the magnetism loop that magnetic conduction subassembly surrounds through through hole, has around the home four drive coils on voice coil loudspeaker voice coil, and four drive coils are connected with power amplifier by four binding posts that are arranged in loudspeaker respectively.When four binding posts from basin frame are inputted tone currents, four drive coils produce equal power in the same way and pump with the variation of the signal of telecommunication in magnetic field, drive oscillating plate and vibration ring to pump, excite air vibration and produce sound.
The invention has the beneficial effects as follows:
Thereby in mega bass auto loud hailer of the present invention, adopt four power amplifiers to drive four drive coils to sound, four drive coils produce equal power in the same way and pump with the variation of the signal of telecommunication in magnetic field, than the loudspeaker that only have a drive coil, loudspeaker of the present invention in same magnetic field by the push-pull effort that produces four times, therefore can make the increase of output power, acoustic pressure increases, and dynamic response is rapid, and low frequency reproduction effect is remarkable.
The present invention guarantees that voice coil loudspeaker voice coil has especially instantaneous burst power of enough power in vertical linearity displacement, thereby guarantee that loud speaker inspires excellent mega bass effect and enough acoustic pressures in narrow and small airtight space, met the automobile-used or demand of small space to mega bass.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
Fig. 1 is circuit module block diagram of the present invention;
Fig. 2 is the exploded view of loudspeaker.
