Embodiment Construction

[0017] Various embodiments of the present invention will be disclosed in the drawings below, and for the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the invention, these practical details are unnecessary. In addition, for the purpose of simplifying the drawings, some well-known structures and components will be shown in a simple schematic manner in the drawings.

[0018] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes acc...

Abstract

The invention discloses a concentric coordinate radiation magnetic path loudspeaker which comprises a support column, cylindrical magnetic steel, a voice coil and a voice production part, wherein a step is arranged at the top end of the support column in an annular manner; the magnetic steel is arranged on the step; a gap is formed between the support column and the magnetic steel; the magnetic steel has radiation magnetic fields after radiation magnetization; the radiation magnetic fields are uniformly distributed close to the inner wall and the outer wall of the magnetic steel; the voice coil comprises a first voice coil and a second voice coil; the first voice coil is arranged inside the gap and is close to the inner wall of the magnetic steel; the second voice coil is arranged outside the magnetic steel and is adhered to the outer wall of the magnetic steel; the centers of the first voice coil and the second voice coil are overlapped; the voice production part is connected with the first voice coil and the second voice coil respectively. By adopting the concentric coordinate radiation magnetic path loudspeaker disclosed by the invention, the number of components for forming magnetic fields in a conventional loudspeaker is reduced, and the manufacturing cost of the loudspeaker is reduced.

Description

technical field [0001] The present invention relates to the technical field of loudspeakers, in particular to a concentric radiating magnetic circuit loudspeaker. Background technique [0002] At present, loudspeakers are widely used. The existing loudspeaker structure generally uses a magnetic circuit structure composed of multiple components such as T-iron, magnets, and Wass to form a magnetic field. The large number of components makes the production cost of the loudspeaker high. SUMMARY OF THE INVENTION [0003] In view of the deficiencies of the prior art, the present invention provides a concentric radiating magnetic circuit loudspeaker. [0004] The concentric radiation magnetic circuit loudspeaker disclosed by the invention comprises: a pillar, a cylindrical magnetic steel, a voice coil and a sounding part; [0005] The top ring of the pillar is provided with a step, the magnetic steel ring is arranged on the step, and there is a gap between the magnetic steel and...
