The utility model proposes a kind of sounding devices.
In the utility model embodiment, as shown in Figures 1 to 4, the sounding device include vibrational system, magnetic circuit system and Auxiliary system, vibrational system include voice coil 700, and magnetic circuit system includes side magnetic conductive board 210, and auxiliary system includes conduct piece 500, are led Electric part 500 includes the corresponding segment 510 being oppositely arranged with about 210 side magnetic conductive board.
It is understood that sounding device can also include shell 100, magnetic circuit system further includes conductive magnetic yoke 400 and is set to Center magnetic path portion and side magnetic circuit part in conductive magnetic yoke 400, conductive magnetic yoke 400 are fixedly connected with shell 100, magnetic circuit system and vibration Dynamic system is contained in the shell 100.Center magnetic path portion includes center magnet steel and center magnetic conductive board 220, side magnetic circuit part subpackage Enclosed tool magnet steel 300 and above-mentioned side magnetic conductive board 210, sub- magnet steel 300 is oppositely arranged with about 210 side magnetic conductive board, so that side magnetic conduction Plate 210 is covered on sub- magnet steel 300.Wherein, magnetic gap is formed between center magnetic path portion and side magnetic circuit part.Vibrational system It further include vibrating diaphragm 800, voice coil 700 is fixed on vibrating diaphragm 800 towards magnetic circuit system side, and voice coil 700 is hanged and set and above-mentioned center In the magnetic gap formed between magnetic circuit part and side magnetic circuit part.Voice coil 700 is electrically connected with conduct piece 500, and then passes through conduction The realization of part 500 is electrically connected effect with external circuit.When thering is electric current to pass through in the voice coil 700 in the magnetic field, voice coil 700 by It is moved to magnetic fields, and then the vibrating diaphragm 800 being firmly connected with it is driven to move, so that vibrating diaphragm 800 is agitated air and realized The effect of sounding.It is understood that sounding device further includes going out acoustic aperture for what is spoken;In addition, in order to guarantee magnetic circuit system With the stability of vibrational system entirety, the sounding device in technical solutions of the utility model can also include front housing 900, front housing 900 positioned at the side close to vibrational system and fixation is covered on shell 100.
Since side magnetic conductive board 210, sub- magnet steel 300 and conductive magnetic yoke 400 are conduct piece, and for Electrical Safety, it will usually right Conductive magnetic yoke 400 is grounded.And in the peculiar structure of some sounding devices, the corresponding segment 510 and side magnetic conductive board 210 of conduct piece 500 It is oppositely arranged up and down, is also correspondingly arranged up and down based on above-mentioned sub- magnet steel 300 with side magnetic conductive board 210, can be understood as conduction herein The corresponding segment 510 of part 500 is set to the side that side magnetic conductive board 210 deviates from sub- magnet steel 300.In order to pursue the compact of product structure Type, the spacing between the corresponding segment 510 and side magnetic conductive board 210 of conduct piece 500 is smaller, and may result in the two part and paste Phenomenon is closed, in the case where magnetic circuit system ground connection, so that conduct piece 500 passes sequentially through side magnetic conductive board 210, sub- magnet steel 300 and leads Magnetic yoke 400 is realized with the earth conducting as a result, the voice coil 700 being electrically connected with conduct piece 500 and external circuit is caused to occur in turn Open circuit conditions.In the unearthed situation of magnetic circuit system, conduct piece 500 is electrically connected with side magnetic conductive board 210, also results in magnetic circuit system Regiment commander's electricity, voice coil electricity shortage, power do not reach requirement and influence acoustical behavior.
In technical solutions of the utility model, being provided between the corresponding segment 510 and side magnetic conductive board 210 of conduct piece 500 is prevented The insulating layer that the two electrically conducts, so that no matter how small spacing is between side magnetic conductive board 210 and corresponding segment 510 can realize insulation Effect, to avoid the case where being connected between conduct piece 500 and side magnetic conductive board 210.
Specifically, the insulating layer between corresponding segment 510 and side magnetic conductive board 210, which is arranged in, can fix stickup or coated on leading Electric part 500 is perhaps on side magnetic conductive board 210 or insulating layer can be directly located between conduct piece 500 and side magnetic conductive board 210 Insulating barrier etc..
Technical solutions of the utility model between the corresponding segment 510 and side magnetic conductive board 210 of conduct piece 500 by being provided with absolutely Edge layer, can be avoided conduct piece 500 be powered after with side magnetic conductive board 210 conducting, and then can to avoid 700 electricity shortage of voice coil shadow The case where ringing acoustical behavior, or can be to avoid in the case where magnetic circuit system is grounded, external circuit passes through conduct piece 500 and side Magnetic conductive board 210 and the earth are connected and the route in sounding device are caused the situation of open circuit occur.
As shown in Fig. 2, this is practical for the ease of voice coil 700 by the circuit communication outside conduct piece 500 and sounding device Conduct piece 500 in new technique scheme includes the first pad 520 and the second pad for being connected to 510 both ends of corresponding segment 530, the first pad 520 is used to be electrically connected the circuit outside sounding device for being electrically connected voice coil 700, the second pad 530.
The both ends of corresponding segment 510 are connected separately with the first pad 520 and the second pad 530, then it is understood that conductive First pad 520 and the second pad 530 at 500 both ends of part have same polarity, and voice coil 700 has two leads, wherein one Lead can be connect with the first pad 520, and the second pad 530 can connect (such as can connect with client) with external circuit, The effect being electrically connected is realized with external circuit to realize voice coil 700 by conduct piece 500.
As shown in Figure 1, Figure 2, shown in Fig. 3 or Fig. 4, for the stability for guaranteeing vibrational system and magnetic circuit system installation, the present embodiment Middle auxiliary system includes the shell 100 for accommodating the vibrational system and magnetic circuit system, and side magnetic conductive board 210 and conduct piece 500 are molded In the inner wall of shell 100.It just can so be further ensured that the stabilization installation effect of conduct piece 500 and side magnetic conductive board 210, simultaneously The bonding strength of conduct piece 500 and shell 100 and side magnetic conductive board 210 and shell 100 is also enhanced, is further ensured that sounding fills Integrally-built stability is set, preferable acoustical behavior is made it have.
