Abstract
The utility model discloses a speaker which comprises a magnetic circuit system, a vibrating system and an auxiliary system, wherein the magnetic system comprises a yoke, magnets and pole pieces; the vibrating system comprises a voice coil; two magnets and two pole pieces are respectively provided; opposite magnetic poles of the two magnets are homopolar; two closed magnetic circuits at different heights are formed among the two magnets, the two pole pieces and the yoke; the voice coil comprises a voice coil skeleton and two sections of voice coil wires which are wound on the voice coil skeleton and respectively correspond to the two closed magnetic circuits; and the winding directions of the two sections of voice coil wires are opposite. According to the utility model, the voice coil is set into the two sections of voice coil wires wound on the skeleton, and corresponding to the two sections of voice coil wires, the closed magnetic circuits are respectively arranged, and thus, the length L of the voice coil and the magnetic induction density B of a magnetic field are increased, so that compared with the prior art, the stress of the voice coil is greatly increased, the problems of low sensitivity and reduced voice of the current product are solved and a speaker unit with higher quality can be provided to meet different requirements.
Description
Technical field
the utility model relates to a kind of loud speaker.
Background technology
loud speaker is claimed " loudspeaker " again, is a kind of ten minutes electro-acoustic transducer device commonly used, is widely used in fields such as TV, multimedias.Loud speaker generally comprises vibrational system, magnetic circuit system and three parts of auxiliary system, and wherein magnetic circuit system comprises permanent magnet, magnetic conductive board; Vibrational system comprises taper cone, voice coil loudspeaker voice coil and decides core and prop up sheet; Auxiliary system comprises framework, basin frame, terminal block and dust cap.As shown in Figure 1, the magnetic circuit system of existing loud speaker is by a yoke (1 '), a magnet (2 ') and be arranged on the pole piece (3 ') on the magnet, and vibrational system only contains a voice coil loudspeaker voice coil (4 ') usually.Yoke (1 '), magnet (2 '), magnet (2 '), pole piece (3 ') form closed magnetic circuit (5 '); The extraneous then alternating current of passing to certain intensity for voice coil loudspeaker voice coil (4 '); Just cutting magnetic induction line produces the power (F=BIL) of both direction up and down to voice coil loudspeaker voice coil (4 ') in closed magnetic circuit (5 ') lining, and then the stressed motion of voice coil loudspeaker voice coil (4 ') drives whole loudspeaker vibrational system and moves and sound.The loud speaker of this structure, the stressed F size of voice coil loudspeaker voice coil (4 ') receives certain limitation, thereby shows sound pressure level, the tonequality of loudspeaker, and the sound size has all received restriction to a certain degree, has influenced the effect of loudspeaker greatly.
Summary of the invention
the utility model technical problem to be solved is the deficiency that overcomes prior art, and a kind of improved loud speaker is provided.
For solving the problems of the technologies described above, the utility model is taked following technical scheme:
a kind of loud speaker, it comprises magnetic circuit system, vibrational system and auxiliary system, magnetic circuit system wherein comprises yoke, magnet and the pole piece on the magnet is set; Vibrational system comprises voice coil loudspeaker voice coil; Magnet, pole piece have two respectively, and one of them magnet is arranged on the yoke, on this magnet, are provided with a pole piece; This pole piece is provided with another magnet; Another pole piece is arranged on another magnet, and the relative magnetic pole of two magnet is a homopolarity, forms two closed magnetic circuits that are in differing heights between two magnet, two pole pieces and the yoke; Voice coil loudspeaker voice coil comprises a speech coil framework and is wound on the speech coil framework respectively and two two sections voice coil loudspeaker voice coil leads that closed magnetic circuit is corresponding, and the direction of winding of two sections voice coil loudspeaker voice coil leads is opposite.
according to a concrete aspect, the relative magnetic pole of two magnet is the S utmost point.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
the utility model is made as two sections voice coil loudspeaker voice coil leads that are wrapped on the skeleton with voice coil loudspeaker voice coil, and to being respectively arranged with closed magnetic circuit by two sections voice coil loudspeaker voice coil leads, therefore; The L of voice coil loudspeaker voice coil and the magnetic induction density B in magnetic field increase; Thereby compared with prior art, voice coil loudspeaker voice coil is stressed to be increased greatly, thereby it is low to have solved present product sensitivity; The problem that sound diminishes, and then can provide more that the loudspeaker unit of high-quality meets the different needs.
Description of drawings
are done further detailed explanation below in conjunction with accompanying drawing and concrete embodiment to the utility model.
Fig. 1 is the part-structure sketch map of loud speaker in the prior art
Fig. 2 is the part-structure sketch map of the utility model loud speaker;
wherein: 1,1 ', yoke; 2,2 ', 2a, 2b, magnet; 3,3a, 3b, pole piece; 4,4 ', voice coil loudspeaker voice coil; 40, speech coil framework; 41a, 41b, voice coil loudspeaker voice coil lead; 5 ', 5a, 5b, closed magnetic circuit.
Embodiment
are as shown in Figure 2, and according to the loud speaker of present embodiment, it comprises magnetic circuit system, vibrational system and auxiliary system, and magnetic circuit system wherein comprises yoke 1, magnet 2 and the pole piece on the magnet 2 is set that vibrational system comprises voice coil loudspeaker voice coil 4.Magnet 2, pole piece have two respectively, and one of them magnet 2a is arranged on the yoke 1, on this magnet 2a, are provided with a pole piece 3a; This pole piece 3a is provided with another magnet 2b; Another pole piece 3b is arranged on another magnet 2b, and the relative magnetic pole of two magnet 2a, 2b is a homopolarity, and relative magnetic pole is the S utmost point; Form two closed magnetic circuit 5a that are in differing heights, 5b between two magnet 2a, 2b, two pole piece 3a, 3b and yokes 1; Voice coil loudspeaker voice coil 4 comprises a speech coil framework 40 and is wound on the speech coil framework 40 respectively and two closed magnetic circuit 5a, two sections voice coil loudspeaker voice coil lead 41a that 5b is corresponding, and 41b, and two sections voice coil loudspeaker voice coil lead 41a, the direction of winding of 41b is opposite.
The loud speaker of
the utility model changes the conventional loudspeakers magnetic structure, and two magnet pole orientation of this magnetic circuit are opposite; Simultaneously the direction of two groups of voice coil loudspeaker voice coils coilings is also opposite, like this according to left hand rule (F=BIL), can guarantee that then new magnetic structure voice coil loudspeaker voice coil receives force direction identical in two closed magnetic circuits; Like this, become big because the B in the new magnetic circuit has, L has elongated; So the stressed F of voice coil loudspeaker voice coil increases greatly; It is low that this has just solved present product sensitivity, the problem that sound diminishes, and then can provide more that the loudspeaker unit of high-quality meets the different needs.
More than the utility model has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand the content of the utility model and implements; Can not limit the protection range of the utility model with this; All equivalences of doing according to the spirit of the utility model change or modify, and all should be encompassed in the protection range of the utility model
