Flat plate type bass loudspeaker

Abstract

The invention provides a flat plate type bass loudspeaker, which comprises a vibration diaphragm, at least six independent driving units and an outer casing, wherein the vibration diaphragm is of a rectangular structure and comprises a rigid ball top part and a corrugated rim part, the ball top part is positioned at the center of the vibration diaphragm, the corrugated rim part is positioned at the edge of the vibration diaphragm, each driving unit comprises a voice coil unit and a magnetic circuit unit corresponding to the voice coil unit, the four voice coil units are respectively combined at the four corners of the ball top part of the vibration diaphragm, the other voice coil units are respectively arranged at one group or two groups of opposite edges of the rectangular ball top part, and are arranged in one straight line together with the two voice coils at the edge corners in an equidistant way, the outer casing is provided with mounting holes or voice outlet holes, and the corrugated rim part of the vibration diaphragm is fixedly connected with the peripheral part on the side surface of the outer casing. The flat plate type bass loudspeaker can solve the problems of the heavy voice coils, excessive magnet performance and insufficient driving force.

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 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. [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 electronic devices. . [0004] The woofer with the traditional structure usually adopts a cone-shap...

AI Technical Summary

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

And because the voice coil of this structure is relatively heavy, the sensitivity of the product is not high, and the vibration of the voice coil is easy to be unbalanced

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
