Detailed Description

The following embodiments are exemplary. Although the specification may refer to "an", "one", or "some" embodiment(s) in various places, this does not necessarily mean that each such reference refers to the same embodiment, or that the feature only applies to a single embodiment. Individual features of different embodiments may also be combined to provide other embodiments. Furthermore, the terms "comprise" and "include" should be understood as not limiting the described embodiments to consist of only those features which have been mentioned, and such embodiments may also comprise features/structures which are not specifically mentioned.

Referring to fig. 1A, in an embodiment, a speaker apparatus 100 includes: the loudspeaker device 100 further comprises a surface 102, at least one support member 104 coupled to the surface 102, a frame 106 coupled to the at least one support member 104, a first magnet 108 coupled to the surface 102, a second magnet 110 coupled to the frame 106, wherein the frame 106 is solid in the area of the second magnet 108, and the means for guiding 112 guides the first magnet 108 and the second magnet 110 to face each other such that a gap exists between the first magnet 108 and the second magnet 110.

In the embodiments, the structure of the speaker apparatus is described such that the surface is on the top, as shown in the drawings. For example, if the first magnet is said to be below the surface, it may mean that the first magnet is between the surface and the frame. For another example, if the second magnet is said to be below the frame, it may mean that the second magnet is on another side of the frame than the surface. In other words, the second magnet is then located on the opposite side of the frame compared to the surface. In addition, fig. 1A, 1B, 3, 4, and 5 are sectional views of the apparatus.

In one embodiment, the device is a speaker for producing sound. The loudspeaker may be used as a conventional loudspeaker, for example a computer loudspeaker, a loudspeaker or a television loudspeaker, or as an integrated loudspeaker. An integrated speaker may refer to a speaker integrated in, for example, a wall structure, an electronic device, or a floor panel, and the above-described structure and device are used as part of the speaker.

In one embodiment, the frame is coupled with the support member by a first end and a second end, wherein the second magnet may be placed between the first end and the second end. A solid frame may mean that the frame is an integral body extending from the first end to the second end, without holes in the area of the second magnet. In other words, the frame may be made of a single piece covering the second magnet.

In one embodiment, there is a hole in the frame between the first magnet and the second magnet. The aperture may only partially cover the first magnet and/or the second magnet. The aperture may also completely cover the first magnet and/or the second magnet such that the frame is open adjacent the first magnet and/or the second magnet. This embodiment is not shown in the drawings.

In one embodiment, the apparatus comprises two support members. Referring to fig. 1A, wherein a first end of surface 102 and a first end of frame 106 are coupled together with first support member 104A, respectively, and a second end of surface 102 and a second end of frame 106 are coupled with second support member 104B.
