AI Technical Summary
Existing speakers are prone to sound distortion when playing at high power, and the cost of using a single magnet is relatively high, especially for speakers with 120 magnets or more, where the cost difference is significant.
It adopts a dual-magnet structure, in which the first magnet is sleeved on the iron core and the second magnet is sleeved on the first magnet, with copper foil placed between the two to prevent sound distortion and reduce production costs.
It effectively reduces sound distortion and significantly lowers the production cost of speakers.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of loudspeaker technology, specifically to an anti-distortion loudspeaker. Background Technology
[0002] Speakers are common and used items in our daily lives. They are used to project sound and are an important component of speaker systems.
[0003] Existing loudspeakers consist of a single magnet mounted on an iron core. This can easily lead to sound distortion during high-power playback. Furthermore, the cost of a single magnet that is compatible with the iron core is far higher than that of two magnets joined together, especially for loudspeakers with a magnet capacity of 120 or higher, where the cost difference is even more pronounced. Utility Model Content
[0004] This invention provides an anti-distortion speaker that effectively prevents sound distortion and minimizes the cost of speaker manufacturing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An anti-distortion loudspeaker includes a loudspeaker body, an iron core and a magnet at the rear end of the loudspeaker body, characterized in that the magnet includes a first magnet and a second magnet, the first magnet is sleeved on the iron core, the second magnet is sleeved on the first magnet, and a copper foil is disposed between the first magnet and the second magnet, the copper foil being adhered to the outer edge surface of the first magnet to prevent sound distortion.
[0007] Preferably, the first magnet and the second magnet have the same thickness.
[0008] Compared with the existing technology, the beneficial effects of this utility model are that it can effectively reduce the sound distortion rate and greatly reduce the production cost. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0013] It should be noted that when a component / part is referred to as being "set on" another component / part, it can be directly set on the other component / part or there may be an intervening component / part. When a component / part is referred to as being "connected / linked" to another component / part, it can be directly connected / linked to the other component / part or there may be an intervening component / part. The term "connected / linked" as used herein can include electrical and / or mechanical physical connections / links. The term "including / comprises" as used herein means the presence of a feature, step, or component / part, but does not exclude the presence or addition of one or more other features, steps, or components / parts. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.
[0015] Furthermore, in the description of this application, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Additionally, in the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0016] Please see Figures 1 to 3 As shown, an anti-distortion speaker includes a speaker body 1, which includes the components of an existing speaker. Since this is prior art, it will not be described in detail. At the rear end of the speaker body 1, there is an iron core 2 and a magnet 3. The iron core 2 is a conventional T-shaped iron core. The magnet 3 includes a first magnet 31 and a second magnet 32. The first magnet 31 is sleeved on the iron core 2. The first magnet 31 has a through hole in the middle that matches the iron core 2. The protruding end of the iron core 2 can be inserted into the through hole to achieve assembly with the first magnet 31.
[0017] There is a mounting hole in the middle of the second magnet 32 with a diameter slightly larger than that of the first magnet 31. The second magnet 32 is fitted onto the first magnet 31 through the mounting hole. A copper foil 4 is provided between the first magnet 31 and the second magnet 32. The copper foil 4 is attached to the outer edge surface of the first magnet 31 to prevent sound distortion and improve sound quality.
[0018] In some embodiments, in addition to copper foil 4, other metal foils may be used, and the first magnet 31 and the second magnet 32 have the same thickness.
[0019] This invention can effectively reduce sound distortion and significantly reduce production costs.
[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
