Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordi...

Abstract

The invention relates to the technical field of flat-panel loudspeakers, in particular to a loudspeaker structure. The shell is provided with a cavity matched with the substrate, the vibrating diaphragm is arranged at the open end of the shell, the magnetic loop assembly is fixed in the cavity, and the voice coil assembly is located in the magnetic loop assembly and fixedly connected with the vibrating diaphragm; a coil is wound on the substrate of the voice coil assembly; the magnetic loop assembly comprises magnetic steel on the two sides of the substrate, an upper pole piece and a lower pole piece are arranged on the upper side and the lower side of the magnetic steel respectively, and the two magnetic steel located on the two sides of the substrate are magnetized in the opposite directions in the vertical direction. The substrate can be set into various curve plate types, and the appearances of the magnetic loop assembly and the shell are adaptively changed, so that the loudspeaker can be suitable for different spaces, the space is saved, and the attractive design of an application product of the loudspeaker is facilitated; the upper portion and the lower portion of a coil in the voice coil assembly correspond to an upper pole piece and a lower pole piece respectively, the magnetic field directions of the two adjacent pole pieces are opposite, and the overall stress directions of the coil are consistent by introducing reverse current into the upper portion and the lower portion of the coil.

Description

technical field [0001] The invention relates to the technical field of flat panel loudspeakers, in particular to a loudspeaker structure. Background technique [0002] At present, most of the speakers used in electronic equipment are circular, mainly due to the constraints of the shape of the receiving coil. It is necessary to ensure that the coil is evenly stressed in the magnetic field, so as to ensure the directivity and distortion of the transmission while ensuring the sound pressure. The design of the speaker is affected by the light and thin size of mobile phones, pad audio, etc. The speaker is designed to be rectangular, and the three-magnet / five-magnet method is used to increase the sound pressure, which invisibly increases the cost. [0003] And whether it is a circular design or a rectangular design, its length and width dimensions require a certain size, and it is necessary to reserve a certain space in the product for the speaker or add a BOX structure to the spe...
