Problems solved by technology

[0012] A common disadvantage in some known solutions is that the movement of the diaphragm controlled by the audio driver is limited by the elements connected to the diaphragm
A common disadvantage of another part of the known solutions is that their radiating properties guarantee a controlled but not so perfect omnidirectional sound emission
Furthermore, most of the known solutions have the disadvantage that they are only able to generate sound waves with uniform efficiency in a relatively restricted frequency range

Embodiment Construction

[0030] All embodiments of the loudspeaker of the invention contain: a support structure; a magnetic arrangement fixed to said support structure and defining an air gap; and a diaphragm sheet connected to said support structure. In the case of the loudspeaker of the invention, sheet means that, with the membrane unfolded, it is made of flat material, advantageously by folding and gluing.

[0031] In the loudspeaker of the invention, the diaphragm has the shape of a cylindrical jacket made up of segments. The membrane is constructed from one or more sheet blocks. Advantageously, all segments of the membrane are made from a single piece of sheet material. The individual segments are interconnected such that together they form a cylindrical sleeve-like shape.

[0032] In the context of the present invention, a cylindrical sleeve-like shape means that the surface is defined by generating lines arranged along a traceline connected end to end at right angles to the plane of the tra...

Abstract

The invention relates to a loudspeaker comprising: a support structure; magnetic means (12) fixed to said support structure, defining an air gap (13); and a diaphragm connected to said support structure, made of sheet material. Said membrane has the shape of a cylindrical sleeve consisting of segments (10) connected to each other along demarcation lines running in the direction of the generation line , and the segment has a surface with a curvature greater than that of the overall radius belonging to the cylindrical sleeve-like shape, at least along two demarcation lines with a tongue (11), of which tongue (11) Each extends radially into an air gap (13) and the diaphragm is connected to the support structure by a flexible support unit that engages and allows the flaps (11) (11) moves radially within said air gap (13).

Description

technical field [0001] The invention relates to a loudspeaker. The subject of the invention is in particular a broadband loudspeaker suitable for omnidirectional sound reproduction. Background technique [0002] Loudspeakers of many different configurations are known from the prior art. For example, loudspeakers with so-called strip diaphragms are widely used, which have less distortion and greater loading capacity than other known types. [0003] A loudspeaker with a striped diaphragm is described, for example, in document WO 2000 / 041492 A2. In the solution according to this document, the membrane is shaped like a strip and divided into several segments. The diaphragm is moved where the individual segments meet each other. The segments in both end positions are fixed along their longitudinal direction to the support structure of the loudspeaker. This known loudspeaker is not suitable for omnidirectional sound reproduction, and the fixed segments in the end positions li...
