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 siz

Example Embodiment

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

[0042] The woofer needs a large diaphragm area. In order to provide sufficient driving for the large area diaphragm on the basis of limiting the size of the voice coil and the magnet, the present invention starts from the perspective of dispersing and arranging a plurality of mutually independent driving units, so that the The membrane is driven by a plurality of independent voice coils, and each voice coil corresponds to an independent magnetic circuit unit, so as to realize the miniaturization of the woofer with a more reasonable and effective driving unit layout struc...

Abstract

The invention provides a flat-plate-type woofer speaker which comprises a vibrating diaphragm, at least six driving units which are mutually independent and an outer shell. The vibrating diaphragm is of a rectangular structure and comprises a ball top portion and a folded ring portion. Each driving unit comprises a voice coil unit and a magnetic circuit unit which corresponds to the voice coil unit. Four voice coil units are combined with four angle portions of the ball top portion of the vibrating diaphragm respectively, the other voice coil units are arranged on one set of opposite edges of the ball top portion or two sets of opposite edges of the ball top portion respectively, and the four voice coil units are not in the same line with the two voice coils on the edges. Mounting holes used for containing the driving units and voice-making holes which penetrate through a mounting plane are formed in the outer shell, and the folded ring portion of the vibrating diaphragm is fixedly connected with the peripheral region of the upper lateral face of the outer shell. The flat-plate-type woofer speaker is capable of solving the problems that an existing woofer speaker is heavy in voice coil, magnet performance is surplus and driving force is insufficient.

Description

technical field [0001] The present invention relates to the technical field of sound and electricity, and more specifically, relates to a flat subwoofer and an electronic device using the subwoofer. Background technique [0002] With the progress of society and the development of technology, in recent years, electronic products such as televisions have become thinner and thinner, and people have higher and higher performance requirements for these electronic products, which also requires the thickness of electronic components that are matched with them to be reduced. Small, performance and consistency improvements. -- and cannot be applied to thin electronic devices. [0003] The woofer is an important electronic component widely used in the above-mentioned electronic products. In thin electronic devices such as LCD TVs and notebook computers, it is required to minimize its thickness on the basis of ensuring the performance of the speaker to meet the needs of thin electroni...
