Be that the magnetic circuit system of prior art is applied in the embodiment schematic diagram in the loud speaker such as Fig. 4, this magnetic circuit system comprises rear magnetic conductor 1 and front magnetic conductor 2, be the cavity 11 that is provided with opening in the middle of the magnetic conductor 1 wherein, magnet 3 is holistic block structure and the bottom that places cavity 11, front magnetic conductor 2 is installed in the cavity 11 and conflicts and is arranged on the magnet 3, the bottom of cavity 11 also is provided with magnet centring ring 4, magnet centring ring 4 is set in the outer surface of magnet 3, makes magnet 3 and is connected integral body that connects compactness of magnetic conductor 1 formation.
Because magnet 3 is holistic bulk, the magnetic field of generation a little less than; Magnet 3 places cavity 11 inside, and the top of magnet 3 is provided with again front magnetic conductor 2, and with after the shell of loud speaker is connected, whole magnetic circuit system is under the environment of a sealing, the heat dispersion extreme difference, and this will cause shorten the useful life of whole loud speaker; The magnetic field that magnet 3 produces is subjected to the impact of front magnetic conductor 2, can't concentrate on to greatest extent voice coil loudspeaker voice coil around so that the magnetic field effect is relatively poor.
The utility model content
For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of can Effective Raise magnetic field performance and the magnetic circuit system of magnetic field effect.
For achieving the above object, the utility model provides following technical scheme: a kind of magnetic circuit system, comprise rear magnetic conductor and front magnetic conductor, described rear magnetic conductor comprises base and the newel that is wholely set, front magnetic conductor is set in the other end of the relative base of newel, the lateral surface of described newel is covered with some magnets that closely link to each other, and magnet all places between base and the front magnetic conductor, and respectively with base be connected magnetic conductor and conflict and be connected.
By adopting technique scheme, the lateral surface of newel is covered with some magnets that closely link to each other, and has greatly improved the magnetic field performance; Magnet all places between base and the front magnetic conductor, and this has improved the magnetic energy effect greatly so that magnetic concentrates on around the newel.
The utility model further is set to: described base, newel and magnet are cylindrical-shaped structure, base diameter is greater than the newel diameter, magnet evenly distributes along the circumferencial direction of newel, and the axial length sum of the axial length of magnet and front magnetic conductor equals the axial length of newel.
By adopting technique scheme, base, newel and magnet are cylindric, magnet evenly and closely distributes, this is so that the structure of whole magnetic circuit system is more attractive in appearance, and magnet and the magnet place of being close to all make things convenient for the magnet heat radiation, relatively traditional set-up mode, whole magnetic circuit system has larger area of dissipation, excellent in heat dissipation effect; The axial length sum of the axial length of magnet and front magnetic conductor equals the axial length of newel, so that the connection between rear magnetic conductor, front magnetic conductor and the magnet is compacter, and reliable in structure.
The utility model further is set to: a side of the relative newel of described base is provided with the magnet centring ring, the magnet centring ring be set on the newel and centering post and magnet between, described magnet centring ring and magnet are conflicted and are connected.
By adopting technique scheme, the magnet that is arranged so that of magnet centring ring can more reliablely and stablely place on the base.
