Abstract
The utility model discloses a two impedance monotonys circle vibration system loudspeaker, which comprises a bracket, the inside of support is equipped with vibrations portion, the inboard of vibrations portion is equipped with magnetic circuit portion, magnetic circuit portion includes the magnetism cover, the inside of magnetism cover is equipped with the magnet steel, the last fixed surface of magnet steel is connected with the pole piece, vibrations portion includes the voice coil loudspeaker voice coil, the voice coil loudspeaker voice coil includes that first resistance encloses and second resistance circle, and first resistance circle and second resistance circle all are connected with two strip leads. This two impedance monotonys circle vibration system loudspeaker, under the unchangeable condition of monomer loudspeaker mechanisms can SPL do higher, increase power, make the speaker more can embody the effect that sound is loud, improve the quality, it is thin and little to make the magnet in the loudspeaker, two impedance monotony circles alleviate vibration portion weight, reduce its whole volume, in long -time motion process, the amplitude is little, the loudspeaker noise has been reduced, the stability of loudspeaker is improved, thereby reduce the speaker cost, and can use in multiple type loudspeaker.
Description
Technical field
The utility model relates to loudspeaker manufacturing technology field, is specially a kind of two impedance single-tone circle vibrational system loudspeaker.
Background technology
Current consumer is very high to the requirement of loudspeaker, not only require that its structure is not only thin but also narrow, also require higher to SPL, in view of structure and the acoustics restriction of prior art, Microspeaker sound is loud not, manufacturer generally for the requirement of the SPL aspect reaching consumer, can only by the magnet in loudspeaker be increased, the driving force of loudspeaker is increased with this, realize consumer demand, but what Hui Shi loud speaker mechanism not only became like this is not only high but also large, but also add production cost, at present, about some electro-acoustic products on market, consumer compare favor in volume little, super-thin, sound is large, low and the high-power electro-acoustic product of cost.Current mobile phone, panel computer, notebook computer etc., require very high to SPL, cost is low, and power is high, but current horn designs is difficult to satisfy the demands.
At present, loudspeaker on the market adopt two impedance single-tone circle to alleviate the weight of loudspeaker when moving, do not changing in customer facility situation, although can accomplish that SPL is high, but have that sound is little, vibrational system weight, resistance to power is low, and under long vibration, loudspeaker poor stability, magnet are not only high but also large, cause loud speaker to have high, the bulky shortcoming of cost.
Utility model content
The purpose of this utility model is to provide a kind of two impedance single-tone circle vibrational system loudspeaker, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of two impedance single-tone circle vibrational system loudspeaker, comprise support, the inside of described support is provided with vibrations portion, the inner side in described vibrations portion is provided with magnetic circuit part, described magnetic circuit part comprises magnetic cover, the inside of described magnetic cover is provided with magnet steel, the upper surface of described magnet steel is fixedly connected with pole piece, described vibrations portion comprises voice coil loudspeaker voice coil, described voice coil loudspeaker voice coil comprises the first electrical coil resistance and the second electrical coil resistance, and described first electrical coil resistance and the second electrical coil resistance are all connected with two lead-in wires.
Preferably, the described inwall of magnetic cover is connected with the outer surface thread of magnet steel.
Preferably, described voice coil loudspeaker voice coil outside be also provided with vibrating diaphragm, and the outer ledge of described vibrating diaphragm is fixedly connected with the inwall of support.
Preferably, described first electrical coil resistance and the second electrical coil resistance go between in parallel with four respectively.
Preferably, the output of described magnetic circuit part is electrically connected the input in vibrations portion.
Compared with prior art, the beneficial effects of the utility model are: this pair of impedance single-tone circle vibrational system loudspeaker, when monomer horn mechanism is constant can SPL do higher, improve power, make loud speaker more can embody fullmouthed effect, oil recovery enhancement, make the magnet in loudspeaker thin and little, two impedance single-tone circle alleviates vibration section weight, reduces its overall volume, in prolonged exercise process, amplitude is little, decreases loudspeaker noise, improves loudspeaker stability, thus reduce loud speaker cost, and can apply in polytype loudspeaker.
