Problems solved by technology

If a flat diaphragm is used, combined with a voice coil structure (the voice coil needs to be located close to the edge), the large-area diaphragm requires a relatively large voice coil size, which is difficult to wind and easy to deform
In addition, the magnet size of the existing woofer is relatively large, and the thickness of the washer and the basin frame are small when the thinning is applied, the magnetic circuit system is easily saturated, the magnet performance is excessive, resulting in waste, and the cost is high

Embodiment Construction

[0041] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details. Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] The woofer requires a larger diaphragm area. In order to provide sufficient drive for the large-area diaphragm on the basis of limiting the size of the voice coil and magnet, the present invention starts from the perspective of dispersing and arranging multiple independent drive units, so that the diaphragm The diaphragm is driven by multiple independent voice coils, and each voice coil corresponds to an independent magnetic circuit unit, so as to achieve a thinner woofer with a more reasonable and effective drive unit layout structure.

Abstract

The invention provides a flat-panel woofer, comprising a diaphragm, at least four mutually independent drive units and a casing; the diaphragm is a rectangular structure, including a ball top at the center and a ring portion at the edge; the drive unit includes The voice coil unit and the magnetic circuit unit corresponding to the voice coil unit; the voice coil unit is fitted and fixed on the dome top of the diaphragm; the housing includes a mounting plane and a ring-shaped side wall around the mounting plane. The mounting hole of the magnetic circuit unit and the sound hole passing through the mounting plane, the upper side of the annular side wall is fixedly connected with the ring part of the diaphragm; the number and position of the mounting holes are the same as those of the voice coil attached to the top of the ball of the diaphragm Quantity corresponds to location. The flat-panel woofer provided by the invention can solve the problems of thick voice coil and excessive magnet performance.

Description

technical field [0001] The present invention relates to the technical field of acoustics and electricity, and more specifically, relates to a flat-panel woofer. Background technique [0002] With the advancement of society and the development of technology, in recent years, the volume of electronic products such as televisions has been continuously reduced and thinner. The volume is continuously reduced and the thickness is also reduced, and the performance and consistency are continuously improved. [0003] The woofer with the traditional structure usually adopts a cone-shaped cone-shaped diaphragm. The center of the cone-shaped diaphragm contains a voice coil, and the magnetic circuit system is relatively large and thick. The woofer with this structure has a relatively large thickness, which cannot meet the increasingly thinner demands of current electronic products, and is not very practical. [0004] Moreover, in order to ensure its low-frequency sound effect, the woof...
