Embodiment 2

[0037] Embodiment 2 The magnetic circuit system of the loudspeaker with the dual magnetic circuit structure includes a ring magnet 10 , a T-shaped iron 11 and a washer 4 . The ring magnet 10, the T-shaped iron 11 and the washer 4 are embedded in the 7 holes of the basin frame. The T-shaped iron 11 includes a central cylinder 1101 and a flange 1102, the ring magnet 10 is arranged above the flange 1102, the washer 4 is arranged above the ring magnet 10, and the central cylinder 1101 is arranged inside the ring magnet 10 and the washer 4 In the hole, the gap between the ring magnet 10 and the washer 4 and the central cylinder is a magnetic gap 1102 .

[0038] There is a tuning hole 1101 in the center of the T-shaped iron 11, and the tuning paper 9 is pasted on the outside of the tuning hole 1101, on the bottom surface of the T-shaped iron 11.

[0039] The structure and principle of the present invention have been described above with the loudspeaker of the dual magnetic circuit ...

Abstract

The invention discloses a loudspeaker with a multipath magnetic circuit structure. The loudspeaker comprises a basin stand, a voice diaphragm and a plurality of driving units, wherein the driving units all comprise magnetic circuit systems and voice coils; the magnetic circuit systems are fixed in the basin stand, the edge of the voice diaphragm is fixed to the edge of the opening of the basin stand, one end of the voice coil is located in the magnetic gap of the magnetic circuit system while the other end of the voice coil is fixed to the voice diaphragm; a plurality of voice coils are connected in series. A plurality of subsidiary voice coils connected in series increase impedance and enable finer alt and richer details, meanwhile strong power generated by a plurality of magnetic loops enables the loudspeaker to have better dynamic and transient, sensitivity is remarkably improved, sounds of low and high pitch and alto can be perfectly shown under equivalent volume of sound making, and the sound is clearer and richer in sense of depth.

Description

[0001] [technical field] [0002] The invention relates to a loudspeaker, in particular to a loudspeaker with a multi-magnetic circuit structure. [0003] [Background technique] [0004] For speakers used in flat-panel video equipment such as LCD and PDP, in order to make the entire speaker unit structure narrower and thinner, relatively flat and narrow speaker frame and sound cone are generally used. However, the narrow and elongated shape of the sound cone makes the force on the two ends of the long axis of the sound cone driven by the traditional single magnetic circuit unbalanced, resulting in the increase of nonlinear distortion of the sound cone and the deterioration of sound quality. [0005] The utility model with the patent number CN200820185070.9 discloses a thin loudspeaker with a dual magnetic circuit structure. There are two bottoms of a pot frame, and each bottom of the pot frame is equipped with a main magnet, a magnetic pole core and a secondary magnet. The voi...
